Taylor HoandGitHub f7a01bda7b fix(workflows): preserve multi-channel listing semantics (#6009)
**Category:** fix
**User Impact:** Workflow listings reliably include every accessible
channel, including for users with more than 128 memberships and when
connected to older relays.
**Problem:** Multi-value `#h` filters could lose live delivery, apply
channel scoping after SQL limits, mishandle partial authorization or
revocation, and permit unbounded membership work. Desktop also submitted
every channel in one request, exceeding the relay's new 128-value safety
bound.
**Solution:** Preserve NIP-01 OR semantics across relay query, count,
and live-subscription paths while enforcing authorization and bounded
explicit-channel work before database or Redis operations. Desktop keeps
the older-relay-compatible one-channel-per-filter shape, sends filters
in bounded batches, combines responses, and deduplicates signed events
by event ID.

<details>
<summary>File changes</summary>

**crates/buzz-db/src/event.rs**
Distinguishes authorization channel scopes from explicit `#h` scopes in
list and count SQL so requested channels are applied before limits
without implicitly including global rows.

**crates/buzz-relay/src/handlers/req.rs**
Shares explicit-channel scope extraction and limits, preserves valid OR
siblings when malformed branches cannot match, repairs request-local
membership misses, and registers authorized live subscriptions per
channel.

**crates/buzz-relay/src/handlers/count.rs**
Applies the same bounded explicit-channel authorization to COUNT and
preserves channel scope when a multi-channel request narrows to one
authorized channel.

**crates/buzz-relay/src/api/bridge.rs**
Brings HTTP query and count behavior in line with WebSocket semantics
before SQL execution and rejects over-limit explicit-channel requests
before membership I/O.

**crates/buzz-relay/src/subscription.rs**
Indexes multi-channel subscriptions by every authorized channel and
shrinks, rather than destroys, their scope when one channel is revoked.

**crates/buzz-relay/src/handlers/side_effects.rs**
Releases only revoked channel topics and sends terminal closure only
when no authorized channel remains.

**crates/buzz-test-client/tests/e2e_relay.rs**
Adds ignored relay integration coverage for multi-channel delivery and
valid historical/live behavior with malformed or empty OR siblings.

**desktop/src-tauri/src/commands/workflows.rs**
Builds one single-channel filter per membership, submits at most 128 per
relay request, combines batches, and deduplicates by immutable signed
event ID.

**desktop/src-tauri/src/commands/workflows_tests.rs**
Covers filter compatibility, malformed input, 129-channel batching, and
cross-batch event-ID deduplication.

</details>

## Reproduction steps

1. Join multiple channels containing workflows, open **Workflows**, and
confirm workflows from every accessible channel appear.
2. Repeat with more than 128 memberships and confirm the listing remains
complete rather than failing the relay request.
3. Send a multi-value `#h` query/count and confirm only requested
authorized channels affect SQL limits and counts.
4. Subscribe to channels A and B, revoke A, and confirm B continues
delivering live events.
5. Subscribe with a valid channel branch plus a malformed or empty `#h`
sibling and confirm valid history, EOSE, and post-EOSE live delivery
still occur.

## Validation

At pushed head `c419a923f05e483ab26c006a0b3a80cfb3c73844`:

- Relay request tests: 53 passed.
- Desktop full Rust unit suite: 2,468 passed, 17 ignored.

54f11219ef fix(acp): gate relay-signed workflow messages on their attributed author (#6129)
## Problem

Scheduled workflow `send_message` actions fire and land in the channel
with correct `p` tags for the mentioned agents — but the agents never
wake. The wake-up is silently dropped.

**Root cause:** workflow messages are signed by the **relay keypair**
(`workflow_sink.rs` signs with `state.relay_keypair`), so `event.pubkey`
is the relay's pubkey, not the workflow owner. In `buzz-acp`, the
inbound author gate (`author_allowed`) runs **before** the `p`-tag
mention check. Under the default `respond_to = owner-only`, the relay
pubkey is neither the owner nor a sibling, so every workflow wake-up
dies at the gate with a debug-level `"inbound author gate — dropping
event"`.

The relay-side comment even says the mention `p` tags exist *"so
mentioned agents are woken (wake is p-tag gated)"* — but wake is also
author-gated, and that path was missed.

## Fix

Gate relay-signed workflow messages on their **attributed author** — the
pubkey that created the workflow — instead of the relay pubkey:

- **Relay:** `workflow_sink.rs` now emits an explicit
`buzz:workflow-owner` tag carrying `workflow.owner_pubkey` (the workflow
creator, which the executor already passes as `author_pubkey` and whose
channel access the relay verifies before emitting). Ownership is never
inferred from `p`-tag order; mention `p` tags play no role in
attribution.
- **Harness:** at startup, `buzz-acp` fetches the relay's NIP-11 `self`
pubkey (new `RestClient::fetch_relay_self`, public `/info` endpoint).
Best-effort: fetch failure just logs a warning and preserves pre-fix
behavior.
- **Gate:** an event that is (a) authored by the relay `self` key, (b)
tagged `buzz:workflow`, and (c) carries a well-formed
`buzz:workflow-owner` pubkey is gated on that owner, through the exact
same owner/sibling/allowlist policy as a direct author.

## Security notes (all fail closed)

- No NIP-11 `self` pubkey → no exemption.
- `buzz:workflow` / `buzz:workflow-owner` tags on a non-relay-signed
event → ignored (a member cannot forge the exemption; the relay verifies
signatures on submission and only the relay holds its key).
- Relay-signed event without the tags, or with a malformed owner value
(not 64-hex) → plain author gate.
- Who is @mentioned in the message has no bearing on whose authority is
evaluated.
- A workflow owned by a random channel member still cannot wake an
owner-only agent — the owner's pubkey must pass the same policy.

## Testing

- 7 unit tests (`workflow_attributed_author_tests`) covering
attribution, fail-closed paths, p-tag independence, malformed owner
values, and the forgery case.
- Extended the PG-gated `workflow_send_message_p_tags_mentioned_member`
integration test to assert the `buzz:workflow-owner` tag.
- `cargo test -p buzz-acp`: 785 passed, 0 failed. `cargo test -p
buzz-relay --lib workflow_sink`: 17 passed. Clippy + fmt clean. (9
pre-existing `buzz-relay` failures in unrelated
`api::media`/`api::admin` tests fail identically on the base commit
without this change.)

Found while debugging scheduled automations in a Buzz review-pipeline
channel: two cron workflows fired daily @mentions at agents that never
responded, while direct human @mentions woke them instantly.

Taylor HoandGitHub edc4a09aaa feat(workflows): add responsive library card actions (#6008)
**Category:** improvement
**User Impact:** Users can scan what each workflow does and trigger,
edit, duplicate, enable, disable, or delete it directly from the
library.
**Problem:** The workflow list buried common actions and did not expose
each automation's trigger-to-action shape at a glance.
**Solution:** Add a responsive workflow library with a persistent create
tile, compact trigger/action diagrams, prominent workflow titles with
supporting descriptions, and shared card actions while preserving
existing detail, editor, and run-history entry points. Card toggles
refresh both list and open-detail caches so status and definition stay
consistent.

<details>
<summary>File changes</summary>

**desktop/src/features/workflows/ui/WorkflowActionsMenu.tsx**
Adds a shared card menu for trigger, edit, duplicate, enable/disable,
and delete actions.

**desktop/src/features/workflows/ui/WorkflowCard.tsx**
Reworks cards around the prototype's visual hierarchy: color-coded
trigger, action flow, sentence-case eyebrow, prominent title, supporting
description, status, channel, and update date without a footer clock
icon.

**desktop/src/features/workflows/ui/WorkflowsView.tsx**
Adds the responsive grid, create tile, mutation wiring, and list/detail
cache invalidation. Container breakpoints keep cards two-across at
medium widths and three-across in the 1280px desktop layout.

**desktop/src/features/workflows/ui/workflowDefinition.ts**
Adds immutable enabled-state updates plus narrow trigger and
first-action readers used only to select card icons.

**desktop/src/features/workflows/ui/workflowDefinition.test.mjs**
Covers neutral icon selection, enabled-state immutability, and status
presentation.

**desktop/tests/e2e/workflows.spec.ts**
Covers the create tile, title/description hierarchy, selected-card
enable/disable consistency, and deterministic narrow/medium/wide
captures while retaining existing action coverage.

</details>

## Reproduction steps

1. Open **Workflows** and confirm the create tile stays first as cards
flow from one to three columns with available width.
2. Confirm each card shows a sentence-case trigger eyebrow, prominent
workflow title, supporting description when present, status, channel,
and update date without a clock icon.
3. Open a card's overflow menu and trigger, edit, duplicate,
enable/disable, or delete the workflow.
4. Leave the detail panel open while toggling and confirm its badge and
JSON definition update with the card.

## Screenshots

Real built E2E UI with representative workflow data at three viewport
sizes.

e0940927ff fix(channels): return complete member rosters (#5765)
## Summary

- return complete channel rosters instead of truncating at 1,000 members
- chunk `event_mentions` inserts inside one transaction so large kind
`39002` snapshots remain discoverable by every `p` tag
- add a targeted `buzz-admin reconcile-channels --channel <uuid>`
force-republish path for stale discovery snapshots
- cover a 1,501-member roster, 11,000-tag mention index, and kind
`39002` tag construction past member 1,000

## Why

The relay builds NIP-29 discovery and several authorization decisions
from `get_members()`, but that helper silently returned only the first
1,000 active members. Desktop then counted the truncated kind `39002`
event, while late members could be rejected by roster-scanning member
actions.

Removing the roster cap exposes PostgreSQL's 65,535 bind-parameter
ceiling in mention indexing, so the insert is chunked transactionally to
preserve all-or-nothing indexing.

The existing reconcilers only fill missing discovery events. The
targeted admin option bypasses the separately known 1,000-channel
reconciliation-list ceiling and replaces an existing channel snapshot
using the configured production relay key.

## Attribution

This supersedes and builds on #3166 by @LordMelkor. Thank you for
identifying the roster boundary and contributing the original
complete-roster and mention-index patch. The production roster/query
changes and the two PostgreSQL regressions retain that work's shape;
this PR rebases it onto current `main`, adds relay coverage, and adds
the targeted repair operation requested for rollout.

## Validation

- mandatory pre-push hook: branch-skew, desktop checks/typecheck/tests,

## Rollout

1. Deploy the relay/backend build.
2. Run `buzz-admin reconcile-channels --channel <general-channel-uuid>`
with `BUZZ_RELAY_PRIVATE_KEY` configured.
3. Verify the replacement kind `39002` roster count matches the active
database membership count.

No schema migration or desktop release is required.

2693e0db1f Make workflow run history authoritative in Desktop (#5780)
## Summary

- persist stable workflow run `error_code` values separately from human
diagnostics
- expose NIP-98 authenticated, channel-authorized run history and
approval reads with stable keyset pagination
- connect Desktop to those authoritative reads and return the
relay-created run ID on trigger
- show truthful loading, failure, and pending-trace states, and do not
render approval actions from non-actionable stored hashes

## Validation

- pre-push `branch-skew`, `desktop-typecheck`, `desktop-test`,
`rust-tests`, `desktop-tauri-checks`, and `desktop-check` all passed on
`a097dbe5f`
- Desktop tests: 4,761 passed, 0 failed
- `cargo check -p buzz-relay`
- `git diff --check`

## Remaining gate

This does not claim a relay-backed Playwright workflow journey. The
browser relay bridge still routes workflow invokes through in-memory
handlers; that production-shaped acceptance gate remains follow-up work
before Workflows can leave preview.

8a2c9af2db feat(deletion): add durable whole-community deletion (#4425)
## Summary

Adds a durable, operator-controlled V1 for deleting an entire Buzz
community without deleting another tenant's data.

The workflow is exposed through `buzz-admin deletions`:

- `sweep` records independent fleet storage-taxonomy observations
- `submit`, `list`, `inspect`, and `approve` manage a deletion request
- `unblock` resumes a fail-closed request after an operator records
remediation identity and reason
- `run` and `drain` execute bounded work

Requests advance through a PostgreSQL-backed state machine and stop at
`retention_pending` after logical deletion has been independently
verified across PostgreSQL, object storage, and Redis.

This PR ships the engine and CLI, not a continuously running worker or
Kubernetes packaging. For V1, a cluster/VM administrator invokes
`/usr/local/bin/buzz-admin` from the existing relay image, for example
with `kubectl exec` or an equivalent container/VM exec path.

## What whole-community V1 removes

For the target community, V1 removes:

- rows from the allowlisted community-scoped PostgreSQL catalog,
including members, profiles, authored events and bodies, DMs, reactions,
mentions, memberships, tokens, workflows, moderation, audit, feedback,
and rate-limit state
- media sidecars and upload-attribution records under
`_meta/<community>/` and `_uploads/<community>/`
- Git repository pointers under `repos/<community>/`
- Redis keys under `buzz:<community>:*`

The community row survives as a permanent tombstone, and deletion
control-plane records remain as evidence of the request, approval,
execution, and result.

## Safety model

Deletion is not a broad `DELETE CASCADE` followed by optimistic cleanup.
The destructive boundaries are durable and fail closed.

### 1. Inventory and approval

- `submit` resolves the target and freezes the schema plus summary-only
storage inventory.
- Approval is bound to the exact request, community, and frozen
inventory digest.
- Unsupported manifest versions, malformed keys inside the target's
owned prefixes, live scoped-table/write-fence coverage drift,
frozen-inventory mismatch, and approval mismatch block execution rather
than guessing. Migration and catalog revision numbers are not
authorization gates; the executor validates the live safety shape
instead.
- Storage inventory is server-side prefix scoped to exactly:
  - `_meta/<community>/`
  - `_uploads/<community>/`
  - `repos/<community>/`
- The deletion path never lists the whole shared bucket and has no
arbitrary per-community object cap. Its listing work is proportional to
the target community's bindings, not total fleet storage.
- Fleet-wide taxonomy sweeps remain independent observability. They
report unknown writer shapes but do not gate deletion submission,
fencing, or destructive progress. Maintainers must add deletion taxonomy
coverage whenever a new community-owned object-key class is introduced;
writer-coverage tests bind the current media and Git writers to that
contract.

### 2. Quiesce, fence, and destructive freeze

- Writes continue through submission, inventory, and approval. They stop
when execution moves the target into `quiescing` and then establishes
the durable fence.
- Already-admitted external effects finish under heartbeated
serving-write leases; the exact admitted lease may renew while the
community is quiescing, but new lease acquisition is rejected. The
executor drains admitted leases before destructive work.
- Invite minting after quiescing begins fails as typed `AccessDenied`
(HTTP 503 at the relay boundary) before an invite can be persisted.
- Database triggers enforce the community write fence across the
complete catalog of community-scoped tables. Startup/readiness and
destructive execution validate that catalog so a newly added but
unfenced table cannot silently escape.
- **Named isolation assumption — fresh write snapshot.** Every writer
transaction that can reach a community-fenced relation must use
PostgreSQL `READ COMMITTED`; each guarded write therefore observes a
statement snapshot no older than acquisition of the community deletion
lock. `REPEATABLE READ` and `SERIALIZABLE` can retain a pre-fence
snapshot and are unsupported for writers. The writer pool refuses
non-`READ COMMITTED` sessions at connection setup, and both SQL fence
functions reject an explicit per-transaction isolation override with
SQLSTATE `25000`. Configuration-delivered bad isolation can surface
through SQLx as a pool-acquire timeout because every `after_connect`
attempt is rejected; the precise `community writes require READ
COMMITTED isolation` reason remains observable when the SQL guard is
reached. Read-only replica transactions are outside this assumption.
- Holding the shared advisory lock until the guarded write executes is a
separate liveness condition: under `READ COMMITTED`, releasing it early
does not permit resurrection because the trigger rechecks the fence, but
it can turn a fleet sweep into a statement-wide SQLSTATE `55000` abort.
- After the fence closes writers, storage is re-enumerated into chunked
side-table rows. Per-prefix counts and digests bind those concrete keys
to the destructive manifest.
- Manifest chunk insertion, update, and deletion are protected after
freeze. This closes the race where an unbound key could otherwise appear
after the manifest was committed.

### 3. Checkpointed destruction

- Target-owned object bindings are deleted from the frozen destructive
manifest in bounded batches with durable progress.
- The concrete key list lives in chunked side-table rows rather than one
request-row JSON value. It supports large communities, resumable
execution, and terminal cleanup.
- Missing objects are accepted as idempotent crash-window outcomes;
malformed ownership, changed evidence, and unexplained target-prefix
drift fail closed.
- PostgreSQL purging remains scoped by `community_id`, including the
guarded NIP-RS hard-delete path discovered with real Desktop kind
`30078` read-state data.
- Redis cleanup explicitly scans and `UNLINK`s only
`buzz:<community_id>:*`. Natural expiry is insufficient because some
keys, including tunnel generation counters used as fencing state, are
deliberately persistent.

### 4. Independent verification

- PostgreSQL logical absence is checked after purge.
- The three target-owned storage prefixes are freshly inventoried again
and must be empty.
- Redis requires two complete empty namespace scans.
- Only after all three stores pass does the request advance through
`logically_verified` to `retention_pending`.

## What V1 deliberately does not erase

### Shared content-addressed storage

Per-community deletion removes bindings, metadata, attribution records,
and Git pointers. It does **not** physically delete fleet-shared CAS
bytes that another community may still reference:

- media blobs and thumbnails
- Git manifests, packs, and indexes (`manifests/`, `packs/`, and `idx/`)

Safe reclamation requires a separate fleet-wide reachability and
retention GC. Unknown keys elsewhere in the shared bucket do not block
one community's deletion; malformed or unrecognized keys inside that
community's three owned prefixes still fail closed.

### External retained copies

The online logical-deletion proof does not erase object
versions/replicas, database backups/WAL, CDN copies, provider retention
copies, or observability exports. Those require their own retention and
purge controls.

### Member-only erasure

This PR erases a whole community. It does not implement the different
operation "erase one npub while preserving the community."

Removing membership or accepting NIP-09 is not member erasure. A
member-only workflow would need to find and selectively remove or redact
authored event content and pubkeys, profile data, DMs, reactions,
mentions, memberships/roles, tokens, workflows/subscriptions, upload
attribution, moderation/audit history, repository attribution, and
identity embedded in tags or JSON. It would also need explicit rules for
ownership transfer, surviving replies and thread metadata, audit-chain
integrity, immutable Git history, and shared-CAS reachability. That
requires a pubkey-level fence and selective graph rewrite; it is a
separate deletion product, not a safe extension of this whole-tenant
worker.

## In scope

- migration `0029_community_deletion.sql`: requests, approvals, leases,
manifest chunks, checkpoints, tombstones, and the universal write-fence
catalog
- durable executor leases, generations, heartbeats, retry/block state,
and resumable stage transitions
- operator-driven `sweep`, `submit`, `list`, `inspect`, `approve`,
`unblock`, `run`, and `drain` commands
- serving-path fences for database writes and external effects across
event ingest, media, Git, workflow, push, invites, mesh/tunnel, and
related paths
- target-prefix-only storage inventory, summary manifests, post-fence
destructive chunks, and bounded batch deletion
- exact community Redis namespace purge and two-pass absence
verification
- cross-community isolation, crash/resume, manifest-integrity,
writer-taxonomy, and schema/migration regressions
- desired-state `schema/schema.sql` support without requiring a SQLx
migration ledger

## Deferred / not covered

- dedicated Helm/chart worker Deployment, service account, secrets,
probes, resources, and network policy
- autonomous `buzz-admin deletions worker` poll loop and worker-only
health server
- least-privilege separation among migration, relay-serving, and
destructive execution roles
- fleet-wide shared-CAS physical GC
- backup/provider/CDN/observability retention completion
- member-only erasure
- provider-native conditional-delete improvements
- a general force-continue escape hatch; permanent safety failures
remain fail closed unless an operator remediates the cause and records
an audited `unblock`

The removed continuous-worker implementation remains deferred; no remote
follow-up branch is claimed by this PR.

## Validation

### Current PR head and repository state

Current pushed head: `359d8402ee15f049768f54156f67b953c7a7e2ed`, rebased
onto `cc9a2f783375e51a6e8d1f2f9d01d5f7e22813d1` (`origin/main` at push
time). The complete PR diff is now 47 files, 9,834 additions, and 517
deletions.

The bespoke source-scanner stack was removed to keep this PR scoped to
community deletion. Tyler/team requested the underlying fenced-write
safety behavior, not `ast-grep`,
`crates/buzz-db/tests/community_fenced_writes.rs`, its 27 fixtures, or
the new `scripts/lints/community_*.yml` rules. Those scanner-specific
files, dependencies, Hermit links, and runner wiring are absent from the
current tree. The production database write fence, startup/destructive
live-catalog validation, and deletion behavior remain.

Source validation on this exact SHA passed:

- `cargo fmt --all -- --check`
- `bash -n scripts/run-tests.sh`
- `cargo nextest run -p buzz-db --all-targets`: 102 passed, 173 skipped,
0 failed
- `cargo nextest run -p buzz-deletion --all-targets`: 10 passed, 9
skipped, 0 failed
- `cargo nextest run -p buzz-admin --all-targets`: 1 passed, 0 failed
- affected-package/all-target Clippy with warnings denied
- lockfile consistency
- Helm 3.16.4 lint and all 44 chart unit tests
- Helm region controls using that fixture: default
`BUZZ_S3_REGION=us-east-1`, explicit `eu-west-2` override, and
blank-region schema rejection

The prior Kubernetes battery below was run against
`928992237358a3294621ac0280830b77155abc04`. It remains useful evidence
for the patch-equivalent production deletion implementation, but it is
**not** claimed as exact-SHA evidence for current head
`359d8402ee15f049768f54156f67b953c7a7e2ed`; the current cleanup removes
only scanner/test/tooling infrastructure. CI restarted for the new head
after the rebase and is pending. Human review remains
`CHANGES_REQUESTED`.

### Prior-head live Kubernetes deletion and safety gates

The full program used one immutable image, real PostgreSQL, Redis,
MinIO, and a three-relay Kubernetes release:

- source: `928992237358a3294621ac0280830b77155abc04` (**prior head**)

Passed gates at that prior head:

- **Chart/operator region:** default `us-east-1`, explicit nondefault
propagation, blank-region schema rejection, live in-pod environment, and
an in-pod taxonomy sweep over 18 objects with zero unknown.
- **Fenced writers and lifecycle:** open-write/fence ordering;
100-attempt anti-starvation; invite, push matcher, and exhausted-reaper
bystander isolation; non-`READ-COMMITTED` rejection; manifest/tombstone
contracts; eight-failure stage block and audited `unblock`.
- **Destructive lifecycle:** submit → approve → run →
`retention_pending`; PostgreSQL tombstone and Redis/S3 verification
true; zero retries/errors; terminal reruns rejected with exit 5.
- **Fresh 10,001-object crash boundary:** exactly two chunks (10,000 +
1). The executor deleted chunk 0 from MinIO while its PostgreSQL stamp
was row-lock-blocked, was killed with `SIGKILL`, left one object and
both stamps absent, then resumed the same request under generation 2 to
zero objects and terminal state.
- **Independent dead-owner recovery:** a dedicated executor claimed
generation 1, blocked before effects, and was killed through containerd
with `SIGKILL` (no TERM cleanup). The request remained owned and
unreclaimable before lease expiry; a successor claimed generation 2
after 60 seconds and completed with two attempts and zero retries.
- **Three-pod socket isolation:** ordinary NIP-42 and joined
huddle-audio target witnesses on every replica received exact `1008 /
community deleted`; healthy-tenant witnesses on those pods remained
live; deleted-host reconnect returned HTTP 404.
- **Health/provenance:** all replicas independently returned ready and
retained the exact image digest before/after destructive runs and an
audio-enabled rolling restart; PostgreSQL, Redis, and MinIO were healthy
at close.

Instrument corrections were retained as evidence rather than counted as
product failures: a foreground PostgreSQL forward caused an initial
`PoolTimedOut`; Kubernetes pod deletion exercised graceful TERM rather
than dead-owner recovery; shell-background socket witnesses died with
their parent; and the first image build hit the corporate TLS proxy.
Detached forwarding/witnesses, containerd `SIGKILL`, and the configured
internal CA/Artifactory mirror produced the discriminating runs without
weakening product security.

### Prior-head cleanup

For the prior-head Kubernetes run, the Helm release was removed,
namespace absence was verified, run-owned Screen sessions were absent,
and that source worktree remained clean. The evidence manifest was
independently recomputed and every indexed artifact passed `shasum -a
256 -c`. The current `359d8402` source worktree is also clean after the
scanner-only cleanup and push.

Taksh KothariandGitHub 16b7ae7ce6 fix(relay): stop panicking the ingest worker on reactions to project events (#5294)
A NIP-25 reaction whose target is a project root or project comment
(kind
1621 issue, 1618 PR, or a kind-1 comment on one) carries no h tag, so
channel_id is None on the reaction write path. The conformance-trace
emission asserted a channel was always present:

channel: channel_label(channel_id.expect("reaction path has channel")),

so the worker panicked at ingest.rs:2824. The row was inserted before
the
panic, so the client saw a failed request for a persisted event and
retried,
and the duplicate branch carried the same expect, head-of-line blocking
a
durable publish queue forever.

Mirror the message write's three-way split at the same seam:
(Some, true) -> WriteInsert, (Some, false) -> WriteDuplicate, (None, _)
-> WriteInsertGlobal. The conformance vocabulary already models
channel-less
writes; only the reaction path was missing it.

Closes #4936

Taksh KothariandGitHub e8153f8f27 fix(relay): log event kind on the HTTP bridge /events line (#5291)
The HTTP bridge request log recorded route, status, and accepted but not
the event kind, so typing indicators (kind 7) and their deletions (kind
5)
were indistinguishable from real messages (kind 9). Every agent turn
produced
accepted:true lines whether or not a message was actually sent, which
twice
led debuggers to conclude a silent agent had published successfully.

Add kind to the Ok outcome and the tracing::info line so the publish
path is
self-describing without a database query.

Closes #4676

397796c5f3 feat(tracing): add PostgreSQL tracing spans (#3678)
## Why
Expose PostgreSQL datastore latency within existing request traces so
slow logical database operations can be identified without recording
tenant data or query arguments.

## What
- Add client spans around logical PostgreSQL operations across the
database facade, search, audit, replica fencing, and command persistence
- Use a dedicated `buzz_datastore` target and `db.system.name =
"postgresql"` for filtering and backend classification
- Exclude health-check database calls and scrub raw identifiers and
errors from newly traced paths

## Risk Assessment
Medium — this instruments frequently used datastore paths and increases
trace volume when enabled, but does not change SQL execution or
datastore behavior. Existing OpenTelemetry filtering controls export.

## References
- Pre-push clippy and fast unit-test hooks passed

240cdd3ea1 chore: mesh upgrade, clean up legacy special case code, simplify model selection for mesh (#5289)
Shared compute now has exactly two model choices: MeshLLM's virtual
`mesh`
model, or a model you name. Buzz picks between them in one place, and
buzz-agent no longer knows meshes exist.

## What changed

- **MeshLLM v0.74.0 → v0.75.1.** v0.75.0 added
`degrade_to_single_model`, so a
  `model=mesh` request is answered by one served model when there is no
committee to form, instead of failing. v0.75.1 adds Mesh-LLM#1196, which
skips stale pre-0.75 runtime cache entries rather than aborting startup
on
them — without it, anyone who had run mesh on 0.73/0.74 could not start.
- **Deleted the client-side mesh catalog probe.** buzz-agent used to
poll
`/v1/models` (5s TTL, 30s cooldown, two-observation debounce) to decide
whether `mesh` was safe to send. MeshLLM now decides per request, so the
  polling, its hysteresis, and its 503 fallback are gone.
- **One mapping point.** `relay_mesh_wire_model()` turns the stored
value into
a wire name: `auto` becomes `mesh`, a named model passes through. The
spawn
env, the ACP harness, and the readiness probe all use it, so they cannot
disagree — previously `BUZZ_ACP_MODEL` and the probe both said `auto`, a
name
  the mesh does not advertise.
- **Removed the `nostr-relay-pool` advisory exception.** #5404 allowed
RUSTSEC-2026-0243 "after mesh-llm migrates to nostr-sdk >= 0.45".
v0.75.1
does, so the retired crate is gone from both lockfiles and the exception
  would only mask a future advisory for it.
- **Deleted `scripts/ensure-mesh-native-runtime.sh`** and its six
justfile call
sites. It built llama.cpp from source into the runtime cache; the app
already
  downloads the signed release runtime itself, and CI never called it.

## Why it is better

**−639 lines of Rust.** Availability is decided by the node that knows
the
answer, per request, instead of by a client cache that could be stale
for up to
30 seconds. A second worker joining now takes effect on the next request
rather
than after two confirming probes.

## Behaviour change

A 503 on an explicit `mesh` request takes the ordinary transport retry
under
the same model instead of failing over to a second one — there is no
second
model to fail over to now. MoA repairs partial committee results
internally
before it reaches that point.

## Validation

`crates/buzz-relay/examples/mesh_agent_e2e.rs` now sends `mesh` where it
previously sent `auto` or the physical model id, so no leg was covering
what
Buzz actually puts on the wire. 4/4 on gemma-4-E4B, gemma-4-26B-A4B, and
Qwen3-8B — including a real ACP tool call through `mesh` into
buzz-dev-mcp,
asserted by reading the written file back off disk.

Hand-tested in the desktop app on both gemma-4 sizes: picked Auto, agent
logged
`model_id=mesh`, replied in channel.

## Not covered

A committee that forms and then loses a worker returns 502, and that
needs two
workers to reproduce — not testable on one machine.

2777189d96 fix(channels): restore member invitations to private channels (#5493)
## Summary

- restore private-channel invitations for every active member
- keep owner/admin-only enforcement for elevated role grants, active
role changes, and removals
- preserve #4612's unrelated Desktop/mobile failure handling and
hardening
- add relay coverage for the ordinary actor/target role matrix
(`member`, `guest`, `bot`)

## Validation

- pre-push hook passed on `7de700e17642ad7e10155f9537033168d9249268`:
branch skew, Desktop checks/typecheck/tests/Tauri checks, mobile tests,
and Rust tests
- `cargo test -p buzz-test-client --test e2e_relay --no-run`
- `cargo fmt --all -- --check`
- `git diff --check`
- Donut and Mongo independently reviewed the cross-layer authorization
behavior; Donut's role-matrix coverage finding is addressed in this
revision

Taylor HoandGitHub 1922d49cb2 feat(desktop): adding rich link previews to messages (#3818)
## Overview

**Category:** improvement  
**User impact:** Link previews appear in the composer and travel as
privacy-safe sender-authored snapshots, so recipients never contact the
linked site merely by opening a conversation.
**Problem:** Cold-cache link paste could freeze the composer before the
URL painted; recipient-side unfurling leaked visits; invalid or
unresolved preview work could interfere with sending or leave dead cards
behind.
**Solution:** Paint pasted links before starting cold resolver work,
resolve only in the sender's composer, attach only complete validated
snapshots at Send, and render authored snapshots without recipient
fallback fetching.

## Behavior

- **Cold paste stays responsive:** bare and angle-bracket URL paste
paths commit the visible link before resolver work begins.
- **Sender-only fetching:** metadata is resolved while composing;
recipients render only the sender-authored snapshot.
- **Send never waits:** pending, failed, invalid, and unsendable
previews are omitted. They do not block or cancel the message.
- **Terminal misses disappear:** failed, timed-out, or 404 resolver
results remove the composer card while preserving visible link text.
- **Display-text links work:** Markdown links such as `[review the pull
request](…)` produce and send the same snapshots as bare URLs.
- **Compact and Rich presentation:** Compact remains the default; Rich
preserves source description line breaks and paragraphs.
- **Immediate draft-wide dismissal:** clicking × immediately hides all
previews for the draft, suppresses links pasted later, and emits only
`["link-preview", "none"]`. No confirmation detour. Suppression resets
after send or clearing the draft.
- **Zero recipient fallback:** missing, stale, malformed, off-relay,
unsupported, or suppressed snapshots remain ordinary visible links;
recipients never regenerate them.

## Implementation

- Resolve previews from deferred composer URL state so paste can paint
first.
- Upload finished preview media to the active community relay and
snapshot only valid, sendable media references.
- Atomically capture ready snapshots at submit time; never append a late
preview after send.
- Validate snapshot and suppression tags in desktop/native and relay
ingestion, rejecting duplicate or mixed forms.
- Render composer previews as stable 55px attachment cards at desktop
and narrow widths.
- Add deterministic E2E coverage for cold paste,
ready/pending/failed/invalid previews, display-text links, multiline
Rich descriptions, immediate dismissal, later-pasted links, and
suppression reset.

## Validation

Validated head: `9807ba8952f190e76153834abf8ab61dd40be5e2`

- Push hooks passed: `check-push-org`, branch skew, desktop check,
mobile tests, desktop tests, Rust tests, and desktop Tauri checks.
- Focused screenshot E2E at the validated head: 5/5 passed across
Compact/Rich composer and recipient states, 800px/420px geometry,
display-text links, multiline descriptions, and immediate dismissal.
- PR CI was triggered for this exact head and is currently running;
completed checks are green at the time of this update.
- Worktree is clean and both PR head and validated branch resolve to
`9807ba895…`.

ad923353a2 feat(relay): accept kind:30179 private managed-agent events at ingest (#5133)
## What

Relay-only carve-out of the ingest half of #4999: generic EVENT ingest
now accepts kind:30179 (NIP-PMA private managed-agent config). One file,
`crates/buzz-relay/src/handlers/ingest.rs`, 16 insertions / 15
deletions; **two semantic lines**, byte-identical to the ingest hunk of
#4999 at `6f486e88`:

1. `required_scope_for_kind`: 30179 requires `Scope::UsersWrite` — same
arm as its public sibling 30177 and the other owner-authored NIP-AP
kinds.
2. `is_global_only_kind`: 30179 is owner-global, keyed `(pubkey, kind,
d-tag)`; a stray `h` tag must not channel-scope it.

The rest is import reflow plus replacing the guard test with a positive
one (`private_managed_agent_kind_is_owner_scoped_global_user_data`:
asserts UsersWrite scope, global-only, no h-channel scope).

## Why the guard test can be retired

The removed test
(`private_managed_agent_kind_remains_rejected_until_atomic_ingest_exists`)
pinned a stated precondition: *"must not enter generic EVENT ingest
before privacy and aggregate CAS deploy."* Both halves are resolved:

- **Privacy** — the author-only read gates for 30179 shipped to main
with #4593: `AUTHOR_ONLY_KINDS` membership, `req.rs` pre-filter + result
gates, `count.rs`, `event.rs` fanout, and the bridge pre-filter
(`bridge.rs:999-1000` returns `restricted: author-only kinds require
authors=[self]` / 403). Only the author can read the event back.
- **Aggregate CAS** — #4999 settled generation as **advisory**: the `g`
tag is shape-validated, never relay-enforced. Last-write-wins per
coordinate is the contract of record (see the kind:30179 contract blurb
in #4999), so no CAS mechanism is pending on the relay side.

## Why this is inert to existing relays and clients

- No production desktop code on main authors kind:30179 — the codec
(`private_managed_agent.rs`) has zero non-test callers. This PR accepts
a kind nobody can produce yet.
- Content is opaque NIP-44 ciphertext to the relay; the relay never
decrypts it.
- Reads remain author-only via the already-shipped gates above.
- Storage is the standard parameterized-replaceable path already
exercised by kinds 30175–30178. No schema, config, or migration changes.

## Testing

- Full `buzz-relay` package suite at this commit: 859 passed, 1 failed —
`api::mesh_demo::tests::demo_join_forwarded_arm_round_trips_echo` (504
vs 200), which **reproduces identically on clean main `769ac70b`** with
this change stashed; pre-existing/environmental, not introduced here.
- New positive ingest test passes.
- Pre-push hooks green (branch-skew, rust-tests, desktop-tauri-checks).

## Relationship to #4999

#4999 (relay-primary agent config, desktop half) stays DO-NOT-MERGE
pending live relay receipts + real CI; once this lands and deploys, its
live test simplifies to plain `desktop-standalone` against the real
relay, and #4999 rebases to drop its now-duplicate ingest hunk
(identical bytes → trivial rebase).

## Brownfield FTS note (review findings, operator-ruled non-blocking for
this PR)

Max and Sami independently identified that the FTS privacy skip-set is
regime-dependent: migration 0008 installs the positive allowlist (`kind
IN (0, 9, 40002, 45001, 45003)`) **only on an empty events table**; an
already-populated database keeps the 0001/0005 negative skip-list
(wrapped by 0014 to add 30350), which omits 30179 — so on such an
installation this PR admits 30179 rows whose NIP-44 ciphertext gets
indexed by `to_tsvector`. Sami measured both regimes against real
Postgres (brownfield: 30179 INDEXED; fresh: NULL) and demonstrated the
existing drift test only exercises the fresh regime.
`schema/schema.sql:222`'s canonical literal is also the negative list
and omits 30179. Migration dates put any relay deployed with data before
0008 landed (2026-07-13) in the brownfield class.

**Scope of exposure (Sami's trace):** not a content leak —
`event_visible_to_reader` / `is_author_only_event` gates hold on both
search surfaces (`req.rs:725`, `bridge.rs:1770`), so foreign readers
receive nothing. Lost is the storage-level NULL-tsv backstop plus FTS
page budget burned on post-filtered hits.

**Operator ruling (Tyler, events `1472e5b6`, `cbd368ed`):** ship this PR
without an exclusion migration. Safety argument that makes this sound
rather than merely accepted: main has **zero non-test 30179 writers**
until #4999's desktop half deploys — no 30179 rows can exist, so nothing
can be indexed in any regime while this PR is the only half live.



**Additional review characterizations (Sami, non-blocking, on the
record):**
- *Behavioral delta enumerated:* routing triple
(`required_scope_for_kind` / `is_global_only_kind` /
`requires_h_channel_scope`) compared for all 65,536 kinds at base
`769ac70b` vs head `77eeba6e` — exactly one row differs (30179). No
other kind or client changes behavior.
- *"SQL visibility before LIMIT" (NIP-PMA step 2):* no
`AUTHOR_ONLY_KINDS` pushdown clause exists in `buzz-db` (only
`SHARED_GATED_KINDS` has one). Author-only kinds are protected by the
pre-filter (`author_only_filters_authorized`) plus post-filter omission;
mixed-kind filters can burn candidate-page budget on discarded rows.
Pre-existing and identical for 30300/30350 — not introduced here; noted
so the NIP's step-2 checkbox is not read as fully ticked.
- *Envelope validation gap:* 30179 is the only parameterized-replaceable
kind at ingest with no per-kind envelope validator (codec grammar checks
run in the desktop writer, not the relay). Generic limits only (256 KiB,
±15 min, pubkey==identity, d-tag bound). Self-inflicted footgun bounded
to the author's own coordinate — candidate companion to the exclusion
migration in the #4999 rebase, deliberately not added here.

**Bound follow-up (required before/with the #4999 desktop half):** a
0014-shape additive migration (`pg_get_expr` capture + `CASE WHEN kind =
30179 THEN NULL ELSE (<existing>) END` wrap), add 30179 to the
`schema/schema.sql:221` literal, and a brownfield-regime variant of the
FTS drift test, per Sami's finding. Deploy-time spot check if ever
wanted: `SELECT pg_get_expr(d.adbin, d.adrelid) FROM pg_attrdef d JOIN
pg_attribute a ON a.attrelid = d.adrelid AND a.attnum = d.adnum WHERE
d.adrelid = 'events'::regclass AND a.attname = 'search_tsv';`

769ac70b74 fix(media): require authenticated reads (#4610)
This change requires a valid signed Blossom authorization request and
current relay membership for every media GET and HEAD request. It
removes the unauthenticated compatibility path and updates desktop reads
to send the required authorization.

This blocks anonymous retrieval and access after relay-membership
revocation. It does not yet bind a blob to its originating channel, so
someone removed from a private channel can still read a known blob while
remaining a relay member. That channel-ACL follow-up remains required
before closing the full finding.

## Testing

- `git diff --check origin/main...codex/security-media-read-auth`
- Rebased onto `origin/main` at `5c98932`
- Full CI pending

Michael NealeandGitHub 38bf642fcf ci: prove the relay-driven mesh lifecycle — discover, join, infer, deny — with real nodes (#3862)
## Summary

CI now proves the full Buzz shared-compute join story end to end: a
member can discover another member's served model **through the Buzz
relay alone** and run inference over the mesh, while a non-member gets
nothing — the relay rejects its auth, and the mesh refuses to route for
it even holding a leaked endpoint address.

This is deliberately different from mesh-llm's own CI smokes (which
bootstrap two nodes with a hand-carried invite token / mdns): here the
**relay is the control plane**, exactly like the desktop app:

1. **Membership** — identities A and B are added via `buzz-admin`
(kind:13534 NIP-43 roster); C is not.
2. **Advertise** — each member publishes a client-signed kind:30003
discovery note carrying its MeshLLM owner binding and (for the serve
node) `serveTargets[].endpointAddr`, covered by an endpoint-binding
signature — the exact payload shape the desktop coordinator publishes.
3. **Trust** — the serve node derives its admission allowlist from the
relay (statuses ∩ roster) and requires the **exact expected {A, B}
owner-id set** before starting with `TrustPolicy::Allowlist`.
4. **Join** — the client verifies owner + endpoint bindings and
membership, then dials the relay-discovered endpoint (the desktop
join-watcher's `dial_endpoint_addr` step). No out-of-band token.
5. **Infer** — a chat completion against the client's local OpenAI
endpoint routes over QUIC to the serve node's model (CPU, SmolLM2-135M,
~105MB).
6. **Deny (differential)** — the stranger's NIP-42 auth must fail with
the relay's own membership rejection (`restricted: not a relay member` —
successful auth or any unrelated connect error fails the run), and
dialing the leaked endpoint must not produce a routed inference —
**while the trusted client re-proves inference immediately afterwards**,
so a dead serve node can't masquerade as an admission denial.

## What's in the PR

- `crates/buzz-relay/examples/mesh_relay_lifecycle_smoke.rs` — the
harness. One process per node (mesh-llm keeps process-global state under
`~/.mesh-llm`), orchestrator + serve/client/stranger roles,
byte-identical binding payloads to
`desktop/src-tauri/src/mesh_llm/identity.rs` (called out with
keep-in-sync comments). Child stdout is pumped through a reader thread
so every wait has a hard deadline; timed-out children are killed; exit
statuses are checked.
- `scripts/ci-mesh-lifecycle-smoke.sh` — provisions a membership-gated
relay (throwaway owner + signing identities via `buzz-admin
generate-key`), runs the harness, cleans up. Fails fast if :3000 is
already occupied (a stale open relay would mask gating).
- `scripts/start-relay-for-tests.sh` — gains opt-in NIP-43 membership
env passthrough (`BUZZ_REQUIRE_RELAY_MEMBERSHIP` + `RELAY_OWNER_PUBKEY`
+ `BUZZ_RELAY_PRIVATE_KEY`). Default behavior unchanged.
- `.github/workflows/mesh-lifecycle.yml` — separate, path-filtered,
non-required workflow (mesh paths, the harness's dependency crates,
`Cargo.lock`, dispatch), pinned to `ubuntu-24.04`. Caches the mesh
native runtime + HF model keyed on the lockfile hash, so a mesh pin bump
rolls the runtime cache. Uploads relay + harness logs on failure.

## Scope

This is an **independent protocol harness**: it speaks the same wire
protocol and payload shapes as the desktop but re-implements the
binding/verification logic (the desktop crate is outside the workspace).
Regressions inside the desktop's own discovery filtering are the desktop
unit tests' job; what this smoke proves is that the relay + mesh-llm SDK
+ admission stack support the lifecycle end to end.

## Relationship to mesh-llm's CI

Follows the shape mesh-llm's own CI proved stable (tiny CPU model, one
runner, multiple real mesh-llm processes over real QUIC — cf. their
`ci-two-node-client-serving-smoke.sh`), but swaps the token bootstrap
for the relay-driven lifecycle, which is the part only Buzz can test.

## Validation

Green on GitHub Actions (ubuntu-24.04) across three runs, including
after rebases onto the mesh v0.74 upgrade (#3467) and latest main:

```
PASS 1/6: relay-derived allowlist is exactly {A, B}
PASS 2/6: serve member ready + advertised model: jc-builds/SmolLM2-135M-Instruct-Q4_K_M-GGUF:Q4_K_M
PASS 3/6: client member discovered + joined via relay
PASS 4/6: inference routed over the mesh: "PONG"
PASS 5/6: relay rejected the stranger's NIP-42 auth (membership gate)
PASS 6/6: stranger denied (gossip visible, inference rejected: 503 all tunnels failed) while trusted inference still routes
PASS: full relay-driven mesh lifecycle verified
```

Also validated locally on macOS. `cargo fmt --all --check` and `cargo
clippy -p buzz-relay --all-targets -- -D warnings` pass.

## Notes

- The harness follows the repo's mesh `[dev-dependencies]` pin
automatically, so it doubles as a canary for future mesh upgrades (it
already caught the v0.73.1 → v0.74.0 bump during development).
- The stranger "deny" accepts either shape mesh-llm exhibits: no model
visibility at all, or gossip visibility with inference refused —
mesh-llm applies the receiving node's owner policy after the gossip
handshake, so admission gates *routing*, not gossip. The differential
trusted-inference re-check (PASS 6/6) is what makes that a real denial
rather than a dead server.
- Model-visibility windows are tunable via `MESH_CLIENT_WINDOW_SECS` /
`MESH_STRANGER_WINDOW_SECS` if shared runners prove slow — pin a longer
window in the workflow env rather than re-running the job.

e14fff74d0 relay: fuzz WebSocket 1012 restart-close timing on graceful drain (BUZZ_DRAIN_JITTER_MS) (#4542)
## Problem

On SIGTERM the relay sends every live WebSocket a **1012 Service
Restart** close frame via `ConnectionManager::drain_all()` — all in the
same instant (`main.rs` shutdown task → `state.rs::drain_all`). On a pod
holding thousands of sessions, that makes every client reconnect
simultaneously: the thundering-herd reconnect behind the DB pool-timeout
bursts observed on each rolling deploy. Client-side jitter can't fix
this — the desktop client *resets* its backoff to base on a 1012 and
reconnects with only ±25% jitter (`relayClientSession.ts`), so the
spread has to come from the server.

## Change

Add `BUZZ_DRAIN_JITTER_MS` (default `0` = unchanged behavior). The two
paths are kept **deliberately separate** so the default is byte-for-byte
the previously shipped shutdown:

- **Jitter off (`0`/unset, the default):** the original synchronous,
all-at-once `drain_all()` runs unchanged — queue the 1012 on each
connection's control channel, cancel, return. No new machinery on the
default path.
- **Jitter on (`> 0`):** a separate async
`drain_all_jittered(jitter_ms)` spreads each connection's restart close
over an independent uniform delay in **`[1, jitter_ms]`**. Each delayed
close travels a dedicated `RestartClose` channel; the writer flushes the
1012 frame and **acknowledges the flush over a oneshot**, so drain waits
for confirmed delivery (up to `RESTART_CLOSE_ACK_TIMEOUT` = 5s) rather
than assuming it, falling back to cancellation if the channel is
full/closed or the ack times out. The drain future is **owned and
awaited** by the shutdown task, and the 30s hard-drain backstop is
aborted only after a clean drain — so a clean roll exits `0`.

The two methods can be unified and the old one dropped later once the
jittered path is proven for all cases.

- **`config.rs`** — `drain_jitter_ms`: non-negative parse, clamped to
`MAX_DRAIN_JITTER_MS` = **20s** (leaving 10s of the 30s budget for
flush). Junk fails loudly at startup; **empty/whitespace-only is treated
as unset (jitter off)** so a `BUZZ_DRAIN_JITTER_MS=""` kill switch does
not crashloop the relay (matches the sibling env vars in this file).
- **`state.rs`** — `drain_all()` (unchanged synchronous default) +
`drain_all_jittered()` (jittered + flush-ack). Both set the sticky
`draining` flag before the first await. A registration that lands
mid-shutdown always self-signals via the **immediate** control-frame +
cancel path — jitter smears already-established sockets, not late
arrivals.
- **`main.rs`** — shutdown task dispatches: `drain_jitter_ms == 0` →
`drain_all()`, else `drain_all_jittered(...).await`.

## Safety

- **Default off is the currently-committed path.** With jitter unset/0
the shutdown runs the original synchronous `drain_all()` — no restart
channel, no ack wait. Safe to deploy dark and dial up.
- **Shutdown-boundary race preserved.** Sticky flag set before any
await; a late registration self-signals its close with no jitter.
- **Owned + backstopped.** The jittered drain future is awaited; the 30s
hard-drain `process::exit(1)` remains the ceiling. `MAX_DRAIN_JITTER_MS`
(20s) + `RESTART_CLOSE_ACK_TIMEOUT` (5s) = 25s, inside the 30s budget;
5s pre-sleep + 25s = 30s against `terminationGracePeriodSeconds: 60`.

## Known behavior to note (not a blocker, flagged from review)

On a **successful** flush the jittered path deliberately does not cancel
the connection token — teardown then depends on the client echoing our
Close, or on process exit. Compliant clients echo; a silent client rides
to the 30s hard exit. The default (jitter-off) path cancels
deterministically as before.

## Tests

- `config::tests::drain_jitter_defaults_off_and_rejects_junk` — default
off, `20000`, clamp `60000`→`20000`, explicit `0`, junk `"soon"` fails,
**empty `""` and whitespace-only treated as off**.
- `state::tests::drain_all_is_immediate` — default path queues frame +
cancels synchronously.
- `state::tests::drain_all_sends_restart_close_and_cancels_every_conn`,
`drain_all_full_control_buffer_still_cancels`,
`register_after_drain_self_signals_restart_close_and_cancel`.
-
`state::tests::drain_all_jittered_defers_close_until_within_jitter_window`
(paused time).
-
`state::tests::drain_all_jittered_waits_for_writer_acknowledgement_without_cancelling`.
-
`state::tests::drain_all_jittered_cancels_when_restart_channel_is_full_or_closed`.
- `state::tests::drain_all_jittered_cancels_when_flush_ack_times_out`
(paused time — the 5s ack-timeout fallback).

Validation at `46c690940`: `cargo fmt -p buzz-relay --check`, `cargo
clippy -p buzz-relay --all-targets -- -D warnings`, and the drain/config
unit suite all clean. Local live SIGTERM test with a real relay process
+ 200 NIP-42-authenticated sockets — see the PR comment for the
before/after distribution and exit codes.

## Rollout

Ship with default `0`, then set `BUZZ_DRAIN_JITTER_MS` (e.g.
10000–20000) on bb-block first, watch the roll-window pool-timeout
metric, then bb-public. `""` is a safe kill switch. Complements the
preStop `sleep` (stops routing before close).

2ea9385015 fix(reactions): support max-length custom emoji (#3833)
**Category:** fix
**User Impact:** Custom emoji with valid 64-character names can now be
used as reactions without errors.

**Problem:** Buzz accepted 64-character custom emoji names during
registration, but rejected them as reactions after the required
surrounding colons made the payload 66 characters. Validation also
differed between desktop, SDK, relay, and storage boundaries.

<img width="554" height="47" alt="image"
src="https://github.com/user-attachments/assets/4013452f-210e-4dd3-9003-f45ff3b28dc8"
/>

**Solution:** Keep the product limit at 64 ASCII characters for custom
emoji names, enforce it consistently when emoji sets are registered, and
allow only valid matching custom reaction payloads up to 66 characters.
Widen the reaction projection to preserve the wrapped payload while
retaining the existing 64-character limit for ordinary reactions.

<details>
<summary>File changes</summary>

**crates/buzz-sdk/src/builders.rs**
Defines the shared custom emoji boundaries and covers accepted
64-character and rejected 65-character shortcodes.

**crates/buzz-relay/src/handlers/ingest.rs**
Validates emoji-set shortcodes and permits 66-character reactions only
when they are valid colon-wrapped custom emoji with a matching tag.

**crates/buzz-db/src/event.rs**
Adds storage regression coverage for maximum-length custom emoji
reactions.

**crates/buzz-db/src/migration.rs**
Verifies the reaction column migration is applied correctly.

**desktop/src/shared/api/customEmoji.ts**
Enforces the existing 64-character shortcode maximum during desktop
normalization and registration/import.

**desktop/src/shared/api/customEmoji.test.mjs**
Covers the desktop shortcode boundary.

**migrations/0027_long_reaction_payloads.sql**
Widens stored reaction payloads to 66 characters for the two required
surrounding colons.

**schema/schema.sql**
Keeps the desired schema aligned with the migration.

</details>

## Reproduction Steps

1. Register or import a custom emoji whose ASCII shortcode is exactly 64
characters.
2. Select that emoji as a reaction to a message.
3. Confirm the reaction publishes, persists, and renders without an
error.
4. Attempt to register a 65-character shortcode and confirm it is
rejected.
5. Publish an ordinary or malformed reaction over 64 characters and
confirm the relay rejects it.

## Verification

- `cargo test -p buzz-sdk`: 243 passed
- `cargo test -p buzz-db`: 94 passed, 152 Postgres-required tests
ignored
- `pnpm test` in `desktop`: 3,859 passed
- `cargo test -p buzz-relay`: 795 passed, 9 existing
Postgres-unavailable failures, 35 ignored; new reaction boundary tests
pass directly
- `cargo fmt --all -- --check`
- `git diff --check`

efe1893dd3 fix(channels): restrict private-channel invitations (#4612)
This change requires an active owner or administrator for third-party
additions to private channels. The relay validator and transactional
database authority enforce the same rule, including removed-member
reactivation and role-change paths.

Idempotent self-target behavior remains available, while ordinary
members can no longer extend private-channel access to another identity.

997b8caaa4 fix(git): revoke access for banned relay members (#4608)
This change rechecks the durable community ban in the shared Git HTTP
authentication path for advertise, fetch, and push requests. A banned
member is denied even if repository-channel membership still exists, and
restriction lookup errors fail closed.

The additional database lookup happens on every Git HTTP request so
access revocation does not depend on stale session state.

The check also cascades to the NIP-OA owner. Git accepts NIP-OA
attestations on the NIP-98 token, so an agent key can act for its owner
— without the cascade, a banned human would keep clone and push access
through any agent key. This mirrors the NIP-42 gate in `handlers::auth`:
either principal's ban denies the request.

The check runs inside the `GitAuth` extractor, so all three Git routes
inherit it.

## Testing

- `git diff --check origin/main...codex/security-ban-revokes-git`
- Rebased onto `origin/main` at `5c98932`
- `cargo test -p buzz-relay --lib sec005_read_gate_tests`: 8 passed, 7
ignored (Postgres)
- `cargo clippy -p buzz-relay --all-targets -- -D warnings` and `cargo
fmt --check`: clean

Pure tests cover the decision table (agent ban, inherited owner ban, no
attestation). Postgres-gated tests cover the wiring: the real ban row, a
live `compute_auth_tag` attestation, and the 503 fail-closed path.

**Not yet verified:** the three Postgres-gated tests compile and skip
but have not been run — no local Postgres, and CI does not run
`--ignored`. They need `cargo test -p buzz-relay --lib
sec005_read_gate_tests -- --ignored` against a migrated dev database.

067c085f37 Define private managed agent wire protocol (#4593)
## Summary

- reserve kind `30179` for owner-private managed-agent aggregates
- define the fail-closed owner-self NIP-44 v2 envelope and versioned
payload codec
- bind runnable identity/configuration to complete signed
`30175`/`30177` recovery projections
- validate NIP-OA owner→agent attestations and reject self-attestation
- document NIP-PMA authority, migration prerequisites, privacy, and
deployment order
- keep generic relay ingest closed until private storage and atomic
aggregate CAS exist

## Safety boundary

This is the inert protocol/codec slice only. It does not publish
secrets, change agent authority, migrate local records, or enable kind
`30179` ingestion. The relay regression test proves generic EVENT ingest
still rejects the kind.

The finalized migration plan adds later prerequisites for relay-private
storage/CAS, runtime lease/fencing, Desktop cutover, and harness
authentication. Those belong in staged follow-up PRs rather than
expanding this inert foundation.

## Validation

At commit `67f0ea4ebb8d3ccba3a3eb9374e89a7178913f74`:

- `cargo test -p buzz-core` — 246 unit + 2 doc tests passed
- `cargo test -p buzz-relay
private_managed_agent_kind_remains_rejected_until_atomic_ingest_exists`
— passed
- push hooks: Rust tests and desktop checks passed (`2145` desktop tests
passed, `14` ignored)
- `cargo fmt --all -- --check`
- `git diff --check`

## Review

Princess Donut cleared security/data integrity with no remaining
high/medium findings. Mongo cleared migration compatibility and wire
grammar. The later runtime lease/fencing protocol was also adversarially
cleared as a plan; implementation slices still require independent
evidence before activation.

Deterministic plaintext/signed-projection/auth-tag interoperability
vectors remain a valuable follow-up, not an S0 merge gate; random NIP-44
ciphertext is intentionally not snapshotted.

Jemiah WestermanandGitHub bc9e6528a7 perf(relay): index channel-id lookups and skip trace-only reads (#4647)
## Problem

`SELECT id, community_id FROM channels WHERE id = ANY($1) AND deleted_at
IS NULL` is the top **Load by waits (AAS)** on the Buzz Postgres writer.
Two independent causes compound, and both are fixed here.

### 1. No index can serve it

`channels` is `PRIMARY KEY (community_id, id)`, and every secondary
index leads with `community_id`:

| Index | Columns |
|---|---|
| *(primary key)* | `(community_id, id)` |
| `idx_channels_nip29_group` | `(community_id, nip29_group_id)` |
| `idx_channels_dm_hash` | `(community_id, participant_hash)` |
| `idx_channels_community_type` | `(community_id, channel_type)` |
| `idx_channels_community_visibility` | `(community_id, visibility)` |
| `idx_channels_created_by` | `(community_id, created_by)` |
| `idx_channels_ttl_expiry` | `(ttl_deadline)` *(partial)* |

The two tenant-independent lookups carry **no `community_id` predicate**
— deliberately:

- `Db::communities_of_channels` — `WHERE id = ANY($1) AND deleted_at IS
NULL`
- `Db::community_of_channel` — `WHERE id = $1 AND deleted_at IS NULL`

That independence is load-bearing, not an oversight: projecting a row's
*true* owning community regardless of the fetch query's `WHERE` clause
is what makes `Inv_NonInterference` non-vacuous. If the fetch ever
dropped its tenant scoping, this lookup would still report the real
label and the checker would catch the mismatch.

But a composite btree is only usable when its leading column is
constrained, so neither query can use the primary key, and nothing else
leads with `id`. **Both sequentially scan `channels` on every call.**

### 2. In production the result is discarded

Both call sites feed `record_read_message_rows` /
`record_read_by_id_rows`, which call `tracer.record(...)`. Production
binds `NoopTracer` (`crates/buzz-relay/src/state.rs`), whose `record`
body is empty.

The existing guard tests `trace_state`, which is `Some` for every
well-formed request — it only goes `None` on malformed pubkey bytes. So
the scan ran on the hot read path and its output was dropped. This is
the classic eager-argument bug: `log.debug("..." + expensiveCall())`
with no `isDebugEnabled()` check.

### 3. Multiplied per filter

The non-search call site sits **inside the phase-3 per-filter loop**, so
a `REQ` carrying N filters performed N sequential scans of `channels`
before responding.

## Changes

**`Tracer::enabled()`** — a capability check on the trait (the
`isDebugEnabled()` of this seam), defaulting to `true`. `NoopTracer`
overrides it to `false`, and both emitters in `req.rs` now gate on it,
skipping the trace-only DB read entirely in production.

**`migrations/0027_channels_id_lookup_index.sql`**

```sql
CREATE INDEX IF NOT EXISTS idx_channels_id_live
    ON channels (id) INCLUDE (community_id)
    WHERE deleted_at IS NULL;
```

- `INCLUDE (community_id)` — both queries select exactly `(id,
community_id)`, so this is covering and can be served index-only.
- Partial on `deleted_at IS NULL` — matches both predicates exactly,
excludes soft-deleted history, and lets Postgres skip the recheck.
- **Not `UNIQUE`.** `id` alone is *not* unique in this table —
`command_executor.rs` documents that `community_of_channel(channel_id)`
is ambiguous because the same channel id can appear under more than one
community. A unique index would encode a false constraint and fail to
build on any database already holding such a pair.

Worth keeping the index even though fix #1 removes the production
caller: it still runs under conformance, and `community_of_channel` has
the same problem on its own paths.

**`schema/schema.sql`** — mirrored, since a test asserts desired-state
parity.

## Conformance is unchanged

This is the part worth reviewing closely. Under a real tracer
`enabled()` returns `true` and **every emit happens exactly as before**
— the gate only skips *building* emit inputs when nothing observes them,
never an emit that would otherwise have been made. The coverage-breach
guard stays non-vacuous.

`CountingTracer` forwards `enabled()` to its inner tracer rather than
inheriting the `true` default. Both directions matter and both fail
silently:

- inheriting `true` over a `NoopTracer` would keep the overhead this PR
removes;
- hardcoding `false` over a live tracer would suppress the emits whose
absence `EmitGuard` reports as `ImplBug` — masking real breaches behind
expected ones.

Covered by a new regression test,
`counting_tracer_delegates_enabled_to_inner`, which asserts delegation
in both directions.

## Verification

- `cargo check -p buzz-conformance -p buzz-relay` — clean
- `cargo clippy --all-targets` — clean, zero warnings
- `cargo test -p buzz-conformance` — 6/6
- `cargo test -p buzz-relay --lib conformance` — 11/11
- `cargo test -p buzz-db --lib migration` — 7/7
- `just test-unit` (pre-push) — green

Migration-count assertions in `crates/buzz-db/src/migration.rs` were
bumped 26 → 27, with content assertions for 0027 following the existing
per-migration pattern (including a guard that it never becomes
`UNIQUE`).

## Open questions for reviewers

1. **Lock strategy.** Built *without* `CONCURRENTLY`, following
migration 0004's precedent, because sqlx runs each migration inside a
transaction and `CREATE INDEX CONCURRENTLY` cannot run in one. This
takes a brief `SHARE` lock on `channels` (blocks writes, not reads) —
small relative to `events`, but an operator preferring zero
write-blocking can pre-build it by hand and `IF NOT EXISTS` makes the
migration a no-op. I could not confirm whether sqlx 0.9 supports a `--
no-transaction` directive; if it does, that may be preferable.

2. **Diagnosis is static.** This comes from reading the source, not from
`EXPLAIN` against the live database. Worth confirming with `EXPLAIN
(ANALYZE, BUFFERS)` on the writer before/after — that also sizes the win
by revealing the real table size and row counts.

3. **Expected impact** scales with average filters-per-`REQ`, which I
did not measure. `pg_stat_statements` ordered by `total_exec_time` would
confirm this query drops off the top and show whether anything else is
scanning the same way.

Tal WeissandGitHub fc598f5f8d fix(git): allow deleting the default branch (#4297)
Tal here, human. Trying to help. This bug bugged me...

## Summary

A repository's first branch becomes its symbolic `HEAD`, and Git's
bare-repository default rejects deleting that branch even when another
branch survives.

This change:

- sets `receive.denyDeleteCurrent=ignore` only for the ephemeral `git
receive-pack` process
- preserves the existing server-side `core.hooksPath` override and
authorization hook
- lets the existing CAS publication logic select a surviving branch as
the next manifest `HEAD`
- adds regression coverage using a real stateless `git receive-pack`
request and a manifest HEAD-selection test

This lets users replace an accidental default branch without deleting
the object-storage manifest pointer.

### Related issue

Fixes #3572

### Testing

- `cargo test -p buzz-relay api::git::` (128 passed, 5 ignored)
- `just ci`
- live E2E roundtrip against a release relay with PostgreSQL, Redis, and
MinIO:
  - created a repository through signed Nostr events
  - verified authorized pushes and rejected unauthorized clone/push
  - pushed a surviving `master` branch
  - deleted the active `main` branch over authenticated Smart HTTP
- freshly cloned the repository and verified `master` became HEAD,
`origin/main` was absent, and repository content remained intact

5765fc74b7 fix(relay): allow open relays to set their NIP-11 workspace icon (kind:9033) (#3998)
## Problem

The desktop deliberately shows the workspace icon editor on open relays
(#2640, gate: `canEditIcon` in
`desktop/src/features/communities/ui/EditCommunityDialog.tsx`) and
defers to the relay-side kind:9033 check — which required an admin/owner
row in `relay_members`. For a community with **no admin/owner row at
all** (the `ensure_configured_community` path, which never writes an
owner), every 9033 was refused and the icon was permanently unsettable.

**Correction from review (thanks @Dawn):** the original version of this
PR claimed nobody holds a role on an open relay. That's false —
`main.rs` bootstraps `RELAY_OWNER_PUBKEY` as owner regardless of
`BUZZ_REQUIRE_RELAY_MEMBERSHIP`, so a production open relay like
bb-block *does* have an owner row, and the old gate was refusing
everyone except that owner. The first revision of this diff would have
silently widened that owner-only control to any NIP-42-authenticated
sender.

## Fix — steward-wins

`may_set_workspace_profile(sender_role, membership_enforced,
community_has_steward)`:

| Relay mode | Community has admin/owner row? | Who may set the icon |
|---|---|---|
| Closed (`require_relay_membership=true`) | any | admin or owner
(unchanged) |
| Open | yes (e.g. bb-block) | admin or owner (unchanged posture) |
| Open | no (genuinely rosterless) | any NIP-42-authenticated sender |

- New DB helper `has_admin_or_owner(community)`
(`crates/buzz-db/src/relay_members.rs`); the call site only queries it
on open relays.
- The rosterless admit logs a `warn!` with the sender pubkey — 9033
writes no audit row and publishes no announcement event (unlike
9030/9031), so this is the only durable attribution.
- Kinds 9030–9032, NIP-42 auth, `AdminUsers` scope, ban gate, and icon
validation are all untouched.
- Doc comment fixed: cited nonexistent `canEditCommunityProfile`; real
symbol is `canEditIcon`.

## Test coverage — closing the mutation gap

Dawn's mutation testing showed the original unit tests pinned only the
helper's truth table: inverting the flag at the call site or deleting
the gate entirely survived the full suite.

- Unit tests now cover the 3-arg truth table (closed
steward-independent, open-with-steward stays steward-only,
rosterless-open admits).
- Two `#[ignore]`d Postgres integration tests drive
`handle_relay_admin_event` with a real `AppState` (open rosterless admit
→ steward appears → roleless refused again; closed relay member
refused). Wired into the Backend Integration CI job as a dedicated
nextest step.
- **Both of Dawn's mutants verified killed** at this head: flag
inversion fails 1 unit test; gate deletion fails both integration tests
(`Ok(())` where `Rejected` expected).

## CI wrinkle found and fixed: pre-existing schema drift

The first Backend Integration run of the new 9033 tests failed with
`column "icon" of relation "communities" does not exist` — migration
`0003_community_icon.sql` added the column, but `schema/schema.sql` (the
desired-state file that CI job applies via pgschema) was never updated.
Pre-existing drift, invisible until a test in that job actually wrote
the column. Fixed in `297148f62` (3-line addition to
`schema/schema.sql`).

## Receipts (at `1b4b52db8` code / `297148f62` head)

- `cargo test -p buzz-relay`: 835 pass, 1 fail —
`api::mesh_demo::tests::demo_join_forwarded_arm_round_trips_echo`,
pre-existing (fails identically at the old base and on clean main);
`telemetry::trace_context_lookup_does_not_enable_callsites` is a known
order-dependent flake, passes in isolation.
- `cargo test -p buzz-db`: 94 pass.
- Both ignored integration tests pass live against local Postgres.
- `cargo fmt --all -- --check`: clean.
- Live-local pass per TESTING.md at this head (release build, relay on
:3199, real WS + NIP-42 via nak):
- open rosterless: roleless key sets icon → NIP-11 serves it; `warn!`
with sender pubkey in the relay log
- open + owner row inserted: fresh roleless key refused ("must be admin
or owner"); owner sets icon
- closed relay (owner bootstrapped, `BUZZ_RELAY_PRIVATE_KEY` set): plain
member refused, owner sets icon, `javascript:` URL rejected, empty icon
clears (NIP-11 → null)

cb9701cd30 feat(relay): accept kind:30621 multi-repo projects at ingest (#3171)
Buzz renders one card per `kind:30617`, so a project spanning several
repositories has no representation.
[NIP-MP](https://github.com/block/buzz/pull/3163) defines `kind:30621`
as an addressable container holding a group's name, description, channel
binding, and member coordinates. This adds the kind to `buzz-core` and
its structural validation to the relay ingest path.

## Event shape

```json
{
  "kind": 30621,
  "tags": [
    ["d", "platform"],
    ["name", "Platform"],
    ["description", "Relay, desktop, and mobile."],
    ["a", "30617:<owner-a-hex>:buzz"],
    ["a", "30617:<owner-b-hex>:buzz-infra"],
    ["buzz-channel", "<channel-uuid>"],
    ["buzz-visibility", "listed"]
  ]
}
```

## Validation at ingest

| Rule | Behavior |
|------|----------|
| `d` tag | exactly one, non-empty (length already bounded by the
generic `D_TAG_MAX_LEN` check) |
| member `a` tag arity | exactly 2 or 3 elements per NIP-01's `a` tag
grammar; a 4th element has no defined meaning and is rejected |
| member `a` tag coordinate | must parse as
`30617:<lowercase-64-hex-owner>:<non-empty-d>` |
| duplicate members | rejected on exact string match of the canonical
coordinate |
| member cap | 64, counted over raw `a` tags |
| metadata cardinality | at most one each of `name`, `description`,
`buzz-channel`, `buzz-visibility` |
| metadata length | `name` ≤ 256 bytes, `description` ≤ 2048 bytes,
`buzz-channel` ≤ 256 bytes, `buzz-visibility` ≤ 256 bytes |
| zero members | valid |
| unknown tags | ignored |

Rejection order is normative so a client can predict which rule fires:
`d`-cardinality → `d`-empty → member-cap → member-arity → coordinate
parse → member-duplicate → metadata cardinality → metadata length.

## Design notes

**No membership authorization.** Members are `a` tags, so one project
may name repositories owned by different pubkeys — the entire point of
the kind. That is safe because membership grants nothing: push policy
reads a repository's own `kind:30617` (`api/git/policy.rs`) and never a
project. `buzz-channel` is a metadata reference, not a routing
directive, so projects are classified global-only.

**Owner-only editing is free.** NIP-33 addressing keys replacement on
`(pubkey, kind, d)`, so one signer can never overwrite another's
project. No relay-side permission check exists or is needed, and
`test_project_same_d_under_two_authors_are_independent` pins it.

**Duplicates are rejected, not deduped.** A relay cannot rewrite tags
inside a signed event without invalidating its id and signature, so the
alternative to rejection is a stored duplicate-member head that every
consumer must apply a first-wins rule to.

**The cap is checked before the duplicate set is built.** Counting raw
`a` tags rather than distinct coordinates means an event naming one
coordinate thousands of times is refused on count, instead of being
bounded only by the relay frame limit.

**No side-effect handler.** Generic NIP-33 replacement and generic
NIP-09 coordinate soft-delete already cover replacement and deletion;
`kind:30621` needs no entry in `is_side_effect_kind`.

## Generic NIP-09 fix carried along

`soft_delete_by_coordinate` (`crates/buzz-db/src/event.rs`) previously
deleted the live coordinate head regardless of the tombstone's own
`created_at`, so a delayed or replayed `a`-tag deletion signed between
two versions destroyed the newer replacement. NIP-09 scopes an `a`-tag
deletion to versions at or before the deletion request, so the `UPDATE`
now carries `created_at <= $5` and `handle_a_tag_deletion` threads the
deletion event's `created_at` through.

The bug predates `kind:30621` and affected every
parameterized-replaceable kind on the generic path — `kind:30617`
repository announcements included — so the fix lands there rather than
as a project special case. `events.created_at` is immutable per row, so
the predicate guarantees a tombstone can never erase a version newer
than itself; the UPDATE re-evaluates its WHERE clause after any lock
wait. Under READ COMMITTED, a same-coordinate replacement racing the
deletion may cause the deletion to evaluate before the new head lands,
returning `Ok(false)` — but that outcome is state-identical to the
deletion having arrived first, a valid Nostr ordering Nostr never fixes.
The return value feeds only a debug log. No coordinate-level lock is
needed.

## Coverage

32 unit tests in `crates/buzz-relay/src/handlers/ingest.rs` pin the
envelope contract (accept: minimal, cross-owner, zero-member, same repo
`d` under two owners, colon-bearing repo `d`, cap boundary, unknown
tags, relay hint on member `a` tag, max-length metadata, stranger-owned
member, uninterpreted metadata values, non-empty content; reject: every
rule above plus valueless `d`/`a` tags). A fixture-driven test
(`project_envelope_validates_all_shared_fixtures`) runs every case in
the shared `NIP-MP.fixtures.json` oracle (11 accept + 20 reject) against
`validate_project_envelope`, so any future change that breaks a case
turns the test suite red.

6 `#[ignore]`d e2e tests in
`crates/buzz-test-client/tests/e2e_project.rs` cover behavior that only
exists past storage — coordinate round-trip, newer-wins replacement, two
authors sharing a `d`, an `a`-tag tombstone that removes the project
while leaving referenced `kind:30617`s intact, and a tombstone
timestamped between V1 and V2 that must leave V2 live. The negative e2e
case asserts on the rejection message so a refusal for an unrelated
reason cannot satisfy it; that is what proves the validator is reachable
from the live write path rather than merely correct in isolation. The
new e2e binary is wired into the Relay E2E job.

The timestamp predicate is additionally pinned at the storage layer by
`coordinate_delete_spares_head_newer_than_the_deletion` in
`crates/buzz-db/src/lib.rs`, which asserts both directions: a stale
tombstone deletes nothing and leaves the newer head readable, and a
tombstone at the head's own timestamp still deletes it. This test is
wired into the Backend Integration job.

23f0c26b1c fix(relay): align NIP-11 max_limit with REQ ceiling (#3635)
Buzz's NIP-11 document advertised `limitation.max_limit: 10_000`, but
the effective websocket REQ page ceiling was `1_000` — a 10x lie.

The websocket REQ path never sets `EventQuery::max_limit`, so
`query_events` applied its own `unwrap_or(1000)` clamp to every
historical query. Only the COUNT fallback (`apply_count_fallback_limit`)
ever raises that clamp. A client that trusts the advertised value asks
for 10,000 events, silently receives 1,000, and — with no error and no
continuation signal — reads that short page as exhaustion. Up to 9,000
events are dropped without anyone noticing.

`MAX_HISTORICAL_LIMIT = 2_000` in `handlers/req.rs` was dead weight for
the same reason: nothing clamped to 2,000 could survive the DB's 1,000
clamp one layer down.

## Change

`buzz_db::DEFAULT_MAX_PAGE_LIMIT` (`1_000`) is now the single source of
truth. It is the `query_events` clamp default, the value both REQ clamp
sites use, and the value advertised as NIP-11 `max_limit`.
`MAX_HISTORICAL_LIMIT` is removed rather than re-pointed — an alias for
a constant used four lines away adds a name without adding meaning.

The NIP-50 search path carries a second, independent bound. It clamps
its emission target to the shared ceiling like any other REQ, but how
many FTS candidates it will scan was bounded separately, by a bare
10-page loop over 100-hit pages. That product only coincidentally
equalled the ceiling, so raising the ceiling — or shrinking a page —
would shrink the scan relative to what clients may now request,
degrading search quality while nothing in the code registered the
change. The page count is now ceiling-divided from
`DEFAULT_MAX_PAGE_LIMIT` over a named `SEARCH_PAGE_SIZE`, so the scan
budget tracks the advertised ceiling by construction.

That budget is a resource policy, not a delivery promise. It bounds
candidates *scanned*, not events *emitted*: post-filtering (NIP-01
match, channel access, reader visibility, dedup) discards an
unpredictable share of every page, so a search result smaller than the
requested limit remains possible. This is not a NIP-11 violation —
`max_limit` is defined as a clamp the relay applies to a requested
`limit`, not a guaranteed count in the response.

Two guards hold the pair together:

- `req_filter_limit_clamps_to_advertised_nip11_max_limit` reads
`max_limit` back out of a built `RelayInfo` and asserts the REQ path
clamps to exactly that number.
- `search_scan_capacity_covers_advertised_nip11_max_limit` asserts the
scan budget covers exactly one advertised ceiling's worth of candidates
— no less, and with no spare page of slack, so the derivation can't be
quietly replaced by a hand-tuned constant that happens to pass today.

## Behavior

Websocket behavior is unchanged: 1,000 was already the real ceiling on
every path, including NIP-50. The advertisement now tells the truth
about it. Raising the effective limit is a capacity decision and is
deliberately not made here.

The generic HTTP bridge's page-2+ offsets do change, as a consequence of
the corrected clamp. `extract_page_offset` sizes a page from
`query.limit` *before* the DB clamp applies, so an absent limit
previously produced an offset of 2,000 and a requested 1,500 produced
1,500 — while the page actually returned held at most 1,000 rows. Both
now produce 1,000. This corrects paging that had been skipping rows the
previous page never returned;
`extract_page_offset_sizes_pages_from_clamped_limit` locks it down.

## Scope note

The bridge's per-endpoint ceilings — `BRIDGE_WINDOW_MAX_LIMIT` (200) for
channel windows and `BRIDGE_THREAD_MAX_LIMIT` (500) for thread reads —
are endpoint contracts on a non-NIP-01 transport, not values NIP-11
speaks for, and are unchanged.

Will PflegerandGitHub 114d40d9d3 feat(relay): gate kind 30178 team-catalog reads behind the shared tag (#3358)
Team catalog projections (`kind:30178`) embed every member's system
prompt, so they need the same read gate personas already have: only the
author sees an unshared event. The gate was hardcoded to `kind:30175` at
six read surfaces plus the SQL pushdown, so rather than adding a second
special case it becomes kind-generic over `SHARED_GATED_KINDS = {30175,
30178}`.

## Kind 30178

New parameterized-replaceable kind, addressed by `(pubkey_o, 30178,
team_id)`. It embeds sanitized member projections instead of referencing
`kind:30175` heads — a foreign reader of a shared team could not
otherwise hydrate members whose own persona events are unshared or, for
built-ins, absent entirely. `kind:30176`'s wire body is untouched, so
device sync keeps its contract.

## Kind-generic shared gate

`buzz_core::kind` replaces `is_persona_shared_kind` /
`is_unshared_persona_event` / `persona_event_is_shared` with
`SHARED_GATED_KINDS` and the kind-agnostic `is_shared_gated_kind` /
`is_unshared_gated_event` / `event_is_shared`. Every read surface
consults the set:

| Surface | File |
|---|---|
| REQ historical delivery + `ids` lookup |
`crates/buzz-relay/src/handlers/req.rs` |
| Live fan-out | `crates/buzz-relay/src/handlers/event.rs` |
| COUNT fallback | `crates/buzz-relay/src/handlers/count.rs` |
| NIP-98 HTTP `/query`, `/count`, `/search` |
`crates/buzz-relay/src/api/bridge.rs` |
| Pre-`LIMIT` SQL pushdown | `crates/buzz-db/src/event.rs` |

The SQL clause generalizes from `kind != 30175` to `kind NOT IN (...)`
bound from `SHARED_GATED_KINDS`, still applied before `ORDER BY … LIMIT`
so a page of newer private events cannot starve an older shared one off
the candidate set. `EventQuery::persona_reader` is renamed
`shared_gated_reader` and `needs_persona_filtering` to
`needs_shared_gate_filtering` to match.

Because the `buzz-core` rename has consumers outside the relay, the four
desktop call sites of `persona_event_is_shared` travel with it:
`desktop/src-tauri/src/commands/personas/pending.rs`,
`desktop/src-tauri/src/event_sync.rs`, and two in
`desktop/src-tauri/src/managed_agents/persona_events.rs`. Each call is
unchanged apart from the name — the persona `shared` projection behaves
exactly as before.

## Ingest validation

`validate_persona_envelope` splits into two reusable pieces —
`validate_shared_tag` (exactly-two-element `["shared","true"]`, at most
one occurrence) and `single_bounded_d_tag` (exactly one `d` tag,
non-empty, `<=64` chars, no ASCII control characters or whitespace).
`validate_team_catalog_envelope` composes both; personas additionally
keep the slug grammar `^[a-z0-9][a-z0-9_-]{0,63}$`.

`kind:30178` deliberately does **not** get the slug grammar. Team ids
are UUIDs or built-in identifiers such as `builtin-team:welcome`, and
the colon is not slug-legal; rewriting ids to fit would break NIP-33
addressing against the team's own `kind:30176` head. The non-empty and
exactly-one checks are load-bearing regardless — without them generic
NIP-33 storage maps a missing `d` onto `(pubkey_o, 30178, "")` and every
team overwrites its predecessor.

The exact two-element `shared` shape is enforced because the SQL
visibility clause is JSONB containment (`tags @>
'[["shared","true"]]'`), which would match a three-element superset such
as `["shared","true","extra"]`.

`kind:30178` is also added to the `Scope::UsersWrite` allowlist and to
`is_global_only_kind`, so a stray `h` tag cannot channel-scope an
owner-authored definition.

## Deferred

`kind:30176` is deliberately not a gate member. Its writers never emit
`shared`, so catalog opt-in semantics do not describe it — it needs
owner-private reads driven by an authenticated principal set, tracked as
a separate follow-up.

## Tests

- 19 new `ingest.rs` unit tests covering the 30178 envelope (UUID and
colon `d` tags, 64-char boundary, non-ASCII bound,
empty/valueless/duplicate/missing `d`, embedded newline, `shared`
false/three-element/duplicate, scope and global-only membership).
- Persona regressions for the valueless `["d"]` shapes, since the
`d`-tag helper is shared by both validators.
- Existing `kind.rs` gate tests generalized and extended to assert the
gate applies to 30178 as it does to 30175.
- New `crates/buzz-test-client/tests/e2e_team_catalog.rs`: 9 WS-level
tests over a live relay covering author reads of unshared heads, foreign
omission from REQ, `ids`-lookup denial, COUNT existence-leak, share and
unshare transitions, and the mixed-kind filter case.
- `.github/workflows/ci.yml` adds `--test e2e_team_catalog` to the Relay
E2E job so the new suite runs.

## Docs

`docs/nips/NIP-AP.md` gains a "Team catalog projection: kind:30178"
section and an "Ingest validation: kind:30178" subsection, records the
gate as kind-generic, documents 30178 deletion vs. unshare semantics,
and adds a security note that sharing a team exposes every member's
instructions even when that member's own `kind:30175` head is unshared.

4933672eb4 feat(mesh): upgrade embedded mesh to v0.74 and harden shared compute (split 1/2 of #3467) (#3741)
## Summary

This is **part 1 of 2** split out from #3467 (per Tyler's request),
carrying only the mesh-scoped changes. The agent/ACP response-behavior
changes and the new `send_message` tool stay in #3467 as part 2. All
commits are @michaelneale's work, cherry-picked with authorship
preserved.

- Upgrade embedded Mesh to v0.74.0 (tag-pinned instead of commit rev)
and use canonical Gemma model IDs.
- Keep shared compute serving through member joins, roster changes, app
recovery, and community switching.
- Wait for actual model readiness and avoid resuming incomplete
downloads after quit.
- Leave `BUZZ_AGENT_THINKING_EFFORT` unset by default so each model's
chat template picks its own thinking default (`none` suppressed Gemma
tool-calling entirely; pinning `low` made Qwen3 burn ~4x output budget).
Explicit agent/persona/global values still win.

## Relationship to #3467

Contains the mesh commits from #3467 (`2cd640b23`, `0ad81c341`,
`ad13ed841`) rebased onto current main, with one deliberate exclusion:
the `crates/buzz-agent/src/llm.rs` reasoning→text parser change from
`2cd640b23` is **not** here. That change unconditionally affects every
OpenAI-compat/Responses provider, so it belongs with the reply-behavior
work in part 2, where it can be reviewed as what it is.

Not included (remaining in #3467 / part 2):
- typed `send_message` tool in dev-mcp + `BUZZ_ACP_SEND_MESSAGE_TOOL`
gating
- plain-reply delivery fallback in buzz-acp
(`BUZZ_ACP_DELIVER_PLAIN_REPLIES`)
- the mesh_agent_e2e P5/P6 rewrite (exists to prove the reply path)
- the two `env.insert` preset opt-ins in `relay_mesh.rs` for the flags
above
- the llm.rs parser change

This PR is independently mergeable; part 2's flags are all off by
default so it can land before or after.

## Testing

- `cargo test -p buzz-relay --locked` — 780 passed (one telemetry test
is order-sensitive under parallel default settings; passes in the
pre-push suite and standalone, unrelated to this diff — files untouched
here).
- `just desktop-tauri-test` (default features) — 1877 passed.
- `cargo test --locked --features mesh-llm` in `desktop/src-tauri` —
1961 passed, including the new relay-mesh preset and
coordinator/recovery tests.
- Both `Cargo.lock`s resolve with `--locked` against the v0.74.0 tag.
- Full pre-push hook suite green (rust-tests, desktop-check/test, tauri
checks).

Live validation of the mesh v0.74 upgrade itself is documented on #3467
(two-Mac cross-version test).

63496cc1d4 feat(replica): portable heartbeat-token fence with snapshot-local reader routing (#3268)
## Summary

Expands read-replica usage on the relay per the Rev 2 design (thread
39d1e174 in #buzz-read-only-replica-usage): replaces the
Aurora-incompatible WAL-LSN read-side fence observation with a portable
**heartbeat token**, makes the freshness proof **snapshot-local to the
serving reader session**, and adds a default-off bounded-staleness gate
for head fetches.

### Probe (writer side, unchanged ordering)
The ordered writer scan is kept verbatim — `S = clock_timestamp()` →
masked-visibility `pg_stat_activity` oldest-xact scan — and now ends by
committing a heartbeat token **last** on the same pinned connection
(single-row `UPDATE replica_heartbeat ... RETURNING token, epoch`,
migration `0026`). The single-row update serializes all pods' probes, so
tokens are globally commit-ordered; the three-bucket completeness
argument carries over unchanged. Ring retains `(token, committed_at,
fence_wall)`; epoch change resets the ring; a same-epoch token
regression (restore adversary) clears the ring **and rotates the epoch
on the writer** so pre-rewind readers fail the epoch check. Cadence 1s.

### Routing (snapshot-local proof)
Every routed read opens `BEGIN ISOLATION LEVEL REPEATABLE READ, READ
ONLY` on a reader session and observes the heartbeat as the
transaction's **first statement** — the proof's snapshot is exactly the
snapshot the page, participants batch, and bridge aux closure read from
(`ReadSession` carries the open transaction; drop = rollback).
Fail-closed everywhere: begin failure, missing heartbeat row, epoch
mismatch, token below the ring, over-budget entry → writer.

- **Predicate B (cursor pages, default-on):** same completeness math as
the existing fence — cursor timestamp must be ≤ the proved wall; thread
candidate-terminal and above-wall pages re-run on the writer.
- **Predicate A (head fetches, default-OFF):** gated by
`BUZZ_REPLICA_HEAD_MAX_AGE_SECS` (0 = off, clamped to fence staleness).
Bounded-stale head semantics are an explicit product decision — **do not
enable anywhere without Tyler's backdated-event-semantics acceptance.**

### Observability
`buzz_db_route_decision{path, decision, reason}` across all five paths,
`buzz_db_replica_heartbeat_age_seconds` gauge, and per-decision debug
logs carrying the proved token plus backend identity: `addr:port pid=N`,
prefixed with `aurora_db_instance_identifier()` when the endpoint
supports it (probed once per process on an autocommit checkout; SQLSTATE
42883 caches a definitive false; identity is evidence, never a routing
gate).

## Review & verification

- **Wren:** full review 9/9/9 at `5f81b10e5`; identity delta re-review
approved at exact head `fedb46368` (90/90 unit, clippy `-D warnings`,
fmt independently reproduced).
- **Max:** local E2E **PASS** at `5f81b10e5` — isolated PG17 writer +
two streaming standbys behind HAProxy; paused-reader legs split exactly
as designed (6 replica/fresh + 6 writer/stale), recovery clean, RR
snapshot hardening observed in runtime logs. Evidence:
`WORK_LOGS/2026-07-28_REPLICA_HEARTBEAT_REPLACEMENT_SHA_E2E.md`.
- **My gates at head (same shell):** buzz-db 90 unit + 143
Postgres-gated green (scratch DBs); buzz-relay 767/768 — lone red is the
pre-existing `mesh_demo` flake, red on base; clippy `-D warnings` + fmt
clean.
- Key regression tests:
`routed_request_holds_one_snapshot_across_page_and_aux`
(mutation-verified both directions), same-epoch rotation,
capability-probe negative, head-gate truth table, divergent-fixture
routing suite.

## Post-merge plan

Merge publishes the immutable `sha-*` main image → bb-public PR pins it
→ ArgoCD sync → Max runs the production cursor-routing canary on Aurora
(positive identity branch proven live). Head gate stays off. Client
`since`-widening ships separately.

## Update — full read routing (Rev 6, commit `9fa3c9c0b`)

Extends routing to the remaining read seams per
`PLANS/REPLICA_FULL_READ_ROUTING_DESIGN.md` Rev 6 (thread cf5deba4 in
#buzz-read-only-replica-usage).

### New routed seams — ALL deploy-default dark
The new seams (`query_events_routed`, `query_events_routed_bounded`,
`count_events_routed`, `get_events_by_ids_routed`,
`query_feed_{mentions,needs_action,activity}_routed`) are
**Bounded-only** and gated on `BUZZ_REPLICA_READ_MAX_AGE_MS`: unset ⇒
every new seam records `writer/disabled` and merging is a no-op. COUNT
and feed/by-ids never take the covered arm (deletion visibility: covered
bounds insert-completeness only). **Note:** the pre-existing cursor
paths (channel windows, thread pages) are *not* gated by this env var —
they route at B=0 today and that status quo is unchanged.

### Reader pool (D4/D5)
- Lazy pool (`connect_lazy`, `min_connections(0)`): reader-down at boot
can't crash the relay; a warn-only boot ping is the only boot-time
visibility, and it primes the Aurora identity capability cache. Priming
is an optimization only — the routed path itself spends a single acquire
budget regardless (see the single-checkout fix below), because a boot
ping that *fails* is correlated with exactly the reader-unavailable case
the budget bound exists for.
- `READER_ACQUIRE_TIMEOUT` = 150ms; a miss fails closed to the writer
with reason **`reader_acquire_timeout`** — named for the mechanism, not
a diagnosis. The budget includes cold connects and sqlx's `size` counts
in-flight dials, so this metric alone does not distinguish contention
from slow connection establishment (see `proved_reader` doc-comment for
the runbook guidance; the pool gauges are 10s samples and are for
capacity planning).
- `BUZZ_DB_READ_POOL_SIZE` sizes the reader independently (invalid/0
inherits writer sizing); `read_pool_stats().max` reports the reader's
own ceiling.

### Community isolation (formal-model question)
Isolation is structural — an explicit `community_id = $n` predicate
compiled into every query builder; no RLS, no session-GUC tenant state
(zero `CREATE POLICY` across migrations). The `_on` variants reuse the
exact same builders with only the executor swapped. Proven by a
seven-seam two-community divergent-fixture test
(`routed_reads_are_confined_to_the_requested_community`),
mutation-tested by Dawn: all four single-predicate stubs killed; the
mention-join feeds are defended in depth (three independent predicates)
so only complete removal leaks there.

### Accepted limitation
D6: client-side staleness on bounded reads (up to `_MS`) is accepted
product behavior when the gate is enabled; gate stays off at merge.

## Update — single acquire budget per routed read (commit `dd26caa9f`)

Max found (and Dawn independently reproduced, 302–330ms measured) that
the boot-unavailable cold path spent **two** stacked
`READER_ACQUIRE_TIMEOUT` budgets: the Aurora capability probe did its
own `pool.acquire()` before `begin_with` acquired again. Fixed by
acquiring **once** per routed read — the capability probe runs on the
held connection (`reader_aurora_capability_on`) and the read-only
`REPEATABLE READ` transaction begins on that same connection
(`Transaction::begin` accepts a `PoolConnection` at `'static` via sqlx's
`MaybePoolConnection`). Reason codes unchanged; capability still never
negatively cached. Measured routed fallback: ~150ms (one budget).

Ships with a PG-gated regression fixture
(`routed_fallback_spends_one_acquire_budget_when_aurora_cache_is_cold`,
authored by Dawn): size-1 reader saturated, capability cache asserted
cold, routes through `count_events_routed`, asserts writer answer +
one-budget elapsed + `writer/reader_acquire_timeout` label
(mutation-tested: `pool_busy` and `reader_validation_error` mutants both
killed). It fails at 330ms on the previous commit and passes on this
one.

### Verification at `dd26caa9f` (pinned toolchain rustc 1.95.0 via repo
`bin/`; ambient rustc 1.89 fails sqlx resolution — always prepend
`bin/`)
- buzz-db: 94 unit + **150/151** PG-gated serial (`--test-threads=1`;
suite is not parallel-safe against one Postgres). The 1 red is
`test_usage_metrics_lock_has_single_owner_and_releases_on_drop` — a
**pre-existing** same-key-same-database advisory-lock collision with any
live relay pointed at the shared `buzz` DB (the relay re-arms
`USAGE_METRICS_LOCK_KEY` on a 300s tick). It passes on a private scratch
DB with the relay still running — verified this run. Remedy is a scratch
`TEST_DATABASE_URL`, **not** terminating lock holders: inspect
`pg_locks`/`pg_stat_activity` and resolve the owning process first; an
idle advisory holder may be a live dev relay. Pre-existing, not a #3268
blocker — filed as #3619.
- buzz-relay: 773/773; clippy `-D warnings` + fmt clean. (`mesh_demo`
echo test is a known pre-existing Redis-dependent flake — Dawn confirmed
it fails identically on the base commit, untouched by this PR.)
- Dawn: independent re-verification at `dd26caa9f` — byte-identical diff
application confirmed, suite reproduced, and fixture proven to still
discriminate (fails at 320ms with only the production fix reverted).
Gate clear. Max: independent rig pass at `dd26caa9f` — 94/94 unit,
**15/15 routing/fallback matrix** (cursor behavior, default-dark seams,
seven-seam confinement, one-snapshot, dead-reader/no-URL fallback,
hard-delete fail-closed, reader max), 773/773 relay, private-DB lock
control. Gate clear; recommends merge + staged bb-block rollout
(no-reader-URL no-op → cursor-only → observe `buzz_db_route_decision` →
conservative nonzero `BUZZ_REPLICA_READ_MAX_AGE_MS`; rollback is
config-only).

## Known gap — CI does not run the PG-backed fixtures (#3622)

Dawn found post-sign-off (confirmed by Max and Eva at `dd26caa9f`):
**every Postgres-backed fixture in this PR is `#[ignore]`d and no CI job
selects it.** `Unit Tests` runs `cargo nextest run -p buzz-db --lib`
(`Justfile:279-285`, ignored tests excluded); the only `--run-ignored
ignored-only` invocations (`ci.yml:690`, `:702`) filter to
`relay_invite::tests`. So the one-budget regression, the seven-seam
isolation fixture, and the fence/floor-guard/fallback tests have zero
automated execution — the verification record above is exhaustive but
manual, at this exact SHA.

Not introduced by this PR (the `#[ignore]` + narrow-filter pattern
predates it; 34 ignored tests total) and not a merge blocker: all new
seams are dark until `BUZZ_REPLICA_READ_MAX_AGE_MS` is set. But it
changes the rollout gate — **do not set a nonzero
`BUZZ_REPLICA_READ_MAX_AGE_MS` in bb-block until CI enforces these
fixtures.** Filed as #3622 (explicit CI selection against the existing
backend-integration Postgres archive; ordering note: #3619 must land
first or be excluded, since widening the filter would select the
colliding usage-metrics lock test).
## Live redteam results (Max, real Helm + PG17 streaming replication at
`dd26caa9f`) — #3643, #3644

Max deployed this exact SHA via the repo chart against a physical
writer/standby pair and attacked it. **The PR's fenced routing passed
every fault**: healthy baseline routes proven on the real standby;
paused WAL replay moved head/cursor reads to `writer/stale`; B=0 moved
routed reads to `writer/disabled`; reader-URL removal rolled back
cleanly.

The redteam also found a **pre-existing** production risk this PR does
not create and does not fix: NIP-50 search builds its own eager,
unfenced pool straight from `READ_DATABASE_URL` (`main.rs:389-402`,
introduced by #2084, present in the deployed bb-block `sha-dd222a5` and
bb-public `sha-22be8bb` images, and both production ESOs already
template `READ_DATABASE_URL`). Measured: ~30s search stall on reader
loss, acknowledged-but-unsearchable writes under replica lag (unaffected
by `BUZZ_REPLICA_READ_MAX_AGE_MS`), fatal eager connect blocking pod
startup when the reader is down, and `replica=true` FTS even at B=0.
Filed as **#3643** (fix: pin FTS to the writer, or fence it like the
routed seams) with **#3644** for the writer-pointing-reader-URL
telemetry gap. Aurora's cluster-ro writer-fallback DNS softens the
outage modes in prod but not the lag mode.

**Revised ladder consequence:** step 2 ("add `READ_DATABASE_URL`, budget
unset") is NOT a no-op with today's binary — it hands FTS an unfenced
replica pool. Rollout order is now: merge (still a true no-op —
bb-block/bb-public already run the unfenced-FTS code and this PR only
adds dark seams) → fix #3643 → CI enforcement #3622 → then reader URL +
budget per the original ladder, re-running Max's three deployment tests
(reader-down latency, reader-down cold boot, paused-replay
read-your-own-write search).
## Activation gate (consolidated) — merge is clear; ALL of the below
precede any nonzero `BUZZ_REPLICA_READ_MAX_AGE_MS`

Six independent verification passes at `dd26caa9f` (Dawn ×2 incl.
byte-level + defang check, Max matrix + live Helm redteam, Wren full
CRUD regression + greenfield 0026 + 151/151 PG, Eva). Every induced
fault was either handled correctly by this PR's machinery or traced to
pre-existing main code. Remaining work gates **activation, not merge**:

1. **#3643** — unfenced NIP-50 FTS pool (pre-existing #2084; live in
prod today; also explains the blackhole search hang Wren observed — the
routed path was measured bounded at 151-152ms against a silent endpoint,
sqlx `inner.rs:252-255`).
2. **#3651** — reader `statement_timeout`: statements after acquire are
unbounded; mid-transaction blackhole reproduced hanging ≥15s (Dawn).
Small fix via `.after_connect` on the reader pool.
3. **#3622** — CI enforcement of the PG fixtures (with #3619 ordering).
4. **Recovery-conflict cancellation live test** — standby cancels a
routed read mid-snapshot → complete writer page, never partial (#3651's
fix also bounds the cancellation-never-arrives shape).
5. **DDL replication lag test** — migration on writer + paused replay +
budget on → fallback, not client-visible SQL errors.
6. **Reader-tx soak** — 30-60min mixed load; no idle-in-tx accumulation
on the standby.

Then Max's three deployment tests (reader-down latency, reader-down cold
boot, paused-replay read-your-own-write search) re-run on the fixed
binary before the first nonzero budget on bb-block.

788b3c002b fix(git): channel binding tooling + author remediation for unbound repos (#3626)
Closes #3527.

Repos announced via vanilla NIP-34 (kind:30617 without a `buzz-channel`
tag) 404 forever: the SEC-005 read gate requires a channel-membership
ACL, and nothing tells the author why or how to fix it. Per the ruling
in the originating thread, this ships **bind/rebind tooling plus a
narrow author-only remediation carve-out** — the shelved owner-circle
approach is intentionally absent.

## Relay
- **`api/git/binding.rs` (new):** shared tri-state binding resolver —
`Bound(uuid)` / `NotBound` / `Broken`. First-tag, fail-closed: a
malformed `buzz-channel` tag is `Broken`, never conflated with "no tag".
Both gates use it.
- **Read gate (`transport.rs`):** a **never-bound** repo read by **its
own announcement author** still returns 404 (status byte-identical to
the generic denial) but the body carries remediation: `run: buzz repos
bind --id <repo> --channel <channel-uuid> — …`. This leaks nothing — the
author announced the repo, and only the author can rebind (30617 is
keyed by `(author, d)`). `Broken` bindings stay generic-denial for
everyone, including the author (revocation shape).
Bound-to-nonexistent-channel stays generic (phase 1; ingest validation
is phase 2).
- **Push gate (`policy.rs`):** unbound denial now returns
`GIT_NO_CHANNEL_BINDING_BODY`. A deploy-skew test pins that the body
carries both the new token (`no_channel_binding`) and the legacy phrase
(`"no channel binding"`) so already-shipped desktops keep matching.
**(Review r1, blocker 2)** `Broken` no longer collapses into "unbound":
it denies 403 `invalid channel binding` for *everyone — including the
announcement owner —* **before** the owner short-circuit, matching the
read gate's fail-closed posture. The remediation token stays
NotBound-only.
- **`ingest.rs`:** side-effect failure `warn!` → `error!` — prod runs
`RUST_LOG=error`, so these failures were invisible during triage.

## Contract
- **`buzz-core/git_perms.rs`:** `GIT_NO_CHANNEL_BINDING_TOKEN` /
`GIT_NO_CHANNEL_BINDING_BODY` consts as the declared cross-component
contract; relay tests and desktop matcher both build on them.

## CLI
- **`buzz repos bind --id <repo> --channel <uuid>`** — rebinds an
existing announcement, preserving other tags.
- **(Review r1, blocker 1)** **`--channel` on `buzz repos create`** —
optional; injects exactly one shape-validated `buzz-channel` tag at
creation via a pure `build_create_announcement` builder, so the primary
create command stops producing repos the relay 404s. UUID
existence/membership stays the relay's authority at git-access time
(same TOCTOU posture as `repos bind`). Overlaps with #3594 (open, head
6bbe38459) — happy to reconcile whichever lands first; this branch also
carries the bind path and tag preservation.

## Desktop
- **Rust:** new `commands/project_git_merge_error.rs` (extracted from
`project_git_workflow.rs` to respect the 1000-line ratchet); maps the
token to a structured `no_channel_binding` error carrying the bind
command.
- **TS:** new `features/projects/lib/projectBranchErrors.ts` + tests —
dual matcher (new token AND legacy spaced phrase);
`ProjectBranchDialogs.tsx` uses it.

## Tests / verification (at head f914c7066, base 581baa625)
- Workspace `cargo test` green; `clippy -D warnings` clean; desktop Rust
1859 pass; TS 3780 pass; tsc/biome/file-size checks pass. Pre-push hooks
re-ran all suites at the pushed head.
- Postgres-gated `sec005_read_gate_tests`: all 6 pass, including
`read_gate_gives_author_of_unbound_repo_remediation_body` — asserts 404
status, `text/plain` content-type, and exact body bytes, distinguishing
remediation from generic denial (a blind `is_err()` can't).
- **New (review r1):** `buzz-cli` emitted-event tests —
`create_with_channel_emits_exactly_one_binding_tag`,
`create_without_channel_emits_no_binding_tag`,
`create_rejects_malformed_channel_uuid` (266/266 pass). Postgres-gated
`push_gate_denies_owner_through_broken_binding` — owner +
malformed-first/valid-second binding → 403 generic body without the
remediation token; never-bound control stays 200, pinning the denial to
`Broken` specifically.
- e2e git tests now bind announcements to a real channel via a
`create_test_channel` helper.

7012d86d52 feat: configure S3 URL addressing style (#3400)
## Summary

- add one strict `BUZZ_S3_ADDRESSING_STYLE=path|virtual` setting shared
by media and Git/CAS storage
- preserve path-style defaults for bundled Compose/Helm MinIO while
supporting Railway's virtual-hosted bucket contract
- fail startup on invalid or non-Unicode values before dependency
connection, and validate the Helm value with the same two choices
- document operator mappings and why endpoint and bucket remain separate
for routing and SigV4 signing

## Best-practice rationale

AWS documents both URL forms and favors virtual-hosted addressing for
S3, while compatibility endpoints such as the bundled MinIO deployment
can require path style. `rust-s3` defaults to virtual/subdomain
addressing and provides `with_path_style()` for the explicit
compatibility case.

Some providers buckets only support as virtual-hosted bucket styles.
This PR therefore uses one explicit, provider-neutral switch rather than
endpoint heuristics or fallback behavior, while retaining `path` as
Buzz's backward-compatible default.

- https://docs.railway.com/storage-buckets#url-style
-
https://github.com/minio/minio/blob/master/docs/config/README.md#domain

## Validation

- `cargo fmt --all`
- `cargo check --workspace --all-targets`
- targeted `buzz-media` and `buzz-relay` parsing/client-construction
tests for defaults, strict errors, and both URL styles
- Helm unittest: 45/45 passed
- Compose config/render validation passed
- local MinIO path-mode relay startup passed the Git A3 conformance
probe and became ready
- unreachable object storage failed startup and readiness never opened
- push hooks completed the broader Rust and desktop suites successfully

22be8bb351 fix(relay): avoid subscription lock inversion (#3413)
## Summary
- drop the `subs` DashMap guard before mutating subscription indexes
- snapshot fan-out candidate vectors so index guards are dropped before
looking up `subs`
- add concurrent fan-out/replacement regression coverage

## Why
`fan_out_scoped` previously held an index guard while `push_match`
acquired `subs`, while CLOSE and same-ID replacement held `subs` while
removing from an index. The reverse ordering made an AB/BA deadlock
reachable and could synchronously park all Tokio workers.

## Validation
- `rustup run 1.95.0 cargo test -p buzz-relay` — 769 library tests
passed, 33 ignored; 11 binary tests passed; doc tests passed
- push hooks with pinned Rust 1.95 — branch-skew, repository Rust
suites, and desktop Tauri suite passed
- `git diff --check`

## Residual risk
Fan-out now clones bounded candidate vectors before matching. This adds
allocation/copy cost proportional to the indexed candidate set, in
exchange for eliminating nested DashMap guards. This fixes the concrete
lock cycle but does not prove every observed production wedge had this
cause.

2ce2d71cc3 feat(relay): make Postgres pool size configurable, default 50 (#3191)
## Summary

- Raise the relay's Postgres pool cap from the `buzz-db` default of 20
to 50 per pool, and expose `BUZZ_DB_POOL_SIZE` for per-deploy tuning
- Applies to the writer pool and, when `READ_DATABASE_URL` is set, the
reader pool; zero/unparsable values fall back to the default
- The `buzz-db` library default is unchanged — only the relay opts into
the larger cap

## Why

During the 2026-07-27 18:40–19:05Z traffic burst on bb-public, per-pod
PG pools pinned at 20 fleet-wide and ~380 requests failed on the 3s
acquire timeout — membership checks, channel access lookups, and
historical queries returning errors to users. The database was nowhere
near a limit: Aurora (db.r8g.8xlarge, ~5,000 max connections) sat at 19%
CPU, 201 connections (~4% of capacity), commit latency flat at 0.01ms.

The 20-connection default was sized for "four relay pods against PG
max_connections=100" (the comment in `buzz-db` says exactly that).
Production now runs 12–15 pods against Aurora — the per-pod cap is the
binding constraint, not the DB.

Budget at the new default: 15 pods × (50 writer + 50 reader + 5 audit) ≈
1,575 potential connections, ~30% of Aurora's ceiling — and actual usage
stays demand-driven (`min_connections` stays 2, connections only open
under load).

Same shape as #2521 (`BUZZ_REDIS_POOL_SIZE`), which fixed the identical
class of ceiling on the Redis side.

## Testing

- `cargo test -p buzz-relay`: 762 passed, 1 failed — the lone red is
`api::mesh_demo::tests::demo_join_forwarded_arm_round_trips_echo`, the
known pre-existing flake; it fails identically on clean `main` at the
same SHA (verified via `git stash` / rerun)
- New test `db_pool_size_env_override_and_invalid_fallback` covers
override, zero, and unparsable fallback
- `defaults_are_valid` extended to pin the new default
- `cargo clippy -p buzz-relay --all-targets -- -D warnings` and `cargo
fmt --check` clean

e94b9aeda0 feat(tracing): add datastore tracing plumbing (#2760)
Configure a dedicated datastore tracing target on the OTLP layer while
preserving explicit logging filters and avoiding span overhead when OTLP
is disabled.

This is in preparation for adding trace spans for datastores used in
Buzz

## Update — 2026-07-27

- Export HTTP requests as `INFO` server spans under `buzz_relay`,
preserving request parentage for datastore spans.
- Configure OTEL span filtering independently with `BUZZ_OTEL_FILTER`,
so `RUST_LOG` changes cannot break trace topology.
- Verify exported HTTP and datastore spans share a trace ID and have the
expected parent/child relationship.

f069a85503 feat(admin): show reported message content in report detail (#3149)
## Summary

- include the reported event's complete stored content, author, creation
time, and deletion state in the admin report detail response
- resolve the event through a community-scoped join so an event ID
collision cannot cross tenant boundaries
- render the message only on report detail, with an explicit unavailable
state when retention has removed it
- preserve the existing report list contract so message bodies are not
returned during queue browsing

## Security

- the existing admin host/origin authorization runs before the detail
database read; a route test pins that ordering
- the target event is selected using both `events.community_id =
moderation_reports.community_id` and `events.id =
moderation_reports.target_event_id`
- the client supplies only the report UUID; it cannot choose a community
or arbitrary event ID
- soft-deleted content is visible only through this restricted admin
detail route and is labeled deleted
- responses retain the admin API's `no-store`, CSP, `nosniff`, frame
denial, and referrer policy middleware

## Testing

- `pnpm -C admin-web check`
- `pnpm -C admin-web test:e2e` (10 passed)
- `cargo test -p buzz-db` (84 passed, 130 ignored)
- `cargo clippy -p buzz-db -p buzz-relay --all-targets -- -D warnings`
- focused admin authorization tests
- pre-push Rust and desktop/Tauri suites passed

The new Postgres integration test is ignored under the repository
convention and will run when explicitly enabled against migrated
Postgres. Local Postgres and Redis were unavailable, so the full
`buzz-relay --lib` run had 8 existing infrastructure-dependent failures
after 749 tests passed.

Fixes all six HIGH findings from the buzz security report, one commit
per finding. Independently reviewed to approval by Max at `0158ae542`,
plus a deep isolated live pass (clean-room compose stack, weird ports,
full product matrix) at the same head — see the buzz-security thread for
evidence. `fe65c07c3` merges current `origin/main` on top (new commit,
no rebase), inheriting the nostr 0.44.6 bump (#3135) and relay-admin ban
gate (#3128).

## Findings and fixes

| Finding | Commit | Fix |
|---|---|---|
| 003 — quinn-proto RUSTSEC-2026-0185 | `e5dcdec72` | Bump quinn-proto
0.11.14 → 0.11.16 (lockfile-only) |
| 002/004 — linkify-it quadratic-parse DoS (GHSA-22p9-wv53-3rq4,
GHSA-v245-v573-v5vm) | `923b3c20f` | pnpm override `linkify-it: ^5.0.2`;
`pnpm why` confirms a single 5.0.2 copy |
| 001 — media reads served unauthenticated by default | `0f277e3e2` |
Helm `requireMediaGetAuth` defaults to `true` + rendered-chart test
pinning the default |
| 006 — removed workflow owners retain webhook-exfiltration authority |
`4749bd56c` | Fail-closed per-fire authority gate (current owner/admin
membership) on **all four** trigger doors (on_event, scheduler
pre-claim, manual trigger, webhook — masked as generic 404), save-time
gate for `call_webhook` defs, durable disable-on-removal wired to kinds
9001 + 9022 |
| 005 — git Smart-HTTP reads ignore channel membership | `e648f2dba` +
`0158ae542` | `authorize_git_read`: caller's **current active
membership** in the repo's bound channel, checked before any
hydration/subprocess on all three read doors (`info_refs` for both
services + `upload_pack` POST). Uniform generic 404 denials (no
membership probing), no repo-owner bypass, first-`buzz-channel`-tag
binding semantics fail closed on ambiguous duplicates (mutation-verified
test). Resolution follows the live kind:30617 announcement, so
deleted/replaced announcements deny immediately. The committed
`e2e-git-perms.sh` guest scenario previously asserted the vulnerability
— now asserts denial. |

## Behavior changes to be aware of

1. **Unbound repos fail closed for git reads.** `buzz repos create`
emits no `buzz-channel` tag, so CLI-created repos without a binding are
unreadable via git HTTP. Correct per finding 005's fail-closed posture;
a follow-up could bind CLI-created repos at creation time.
2. **006 is conservative:** a workflow disabled on owner removal does
not auto-re-enable if the owner is re-added — explicit re-enable
required.
3. Merge conflict resolution in `fe65c07c3`: kept main's
`@radix-ui/react-dismissable-layer` 1.1.19 bump alongside the linkify-it
security override (`pnpm-workspace.yaml` + lockfile).

## Verification at the merge head `fe65c07c3` (same shell)

- buzz-relay `--lib`: 761 passed / 1 failed — the lone red is the known
pre-existing `mesh_demo::demo_join_forwarded_arm_round_trips_echo` 504
flake, present on main
- SEC-005 module incl. PG behavioral matrix: 8/8 (removed-member,
never-member, owner-no-bypass, deleted-30617, malformed/ambiguous
binding, owner-mismatch all denied)
- buzz-workflow 153/0, buzz-db 84/0; `clippy --all-targets -D warnings`
+ `fmt --check` clean
- Desktop JS 3637/3637, tsc clean, biome clean,
file-size/px-text/pubkey-truncation gates clean
- `helm lint` + `helm unittest` (40/40) on `deploy/charts/buzz`
- All five pre-push hooks green (desktop-check, desktop-test,
rust-tests, desktop-tauri-test, branch-skew)

Prior review evidence at `0158ae542` (pre-merge): Max's independent
exact-head approval + clean-room live regression pass
(`WORK_LOGS/2026-07-27_SECURITY_HIGH_LIVE_TEST.md` in his workspace).
Max will re-run the deep local pass at this post-merge head before
merge.

c3084b36d9 fix(cli,relay): resolve agents by verified owner (#2615)
## Context

`buzz users get --name Honey` searches relay-wide profiles and returns
up to 100 identically named results without verified ownership metadata.
An agent resolving “my Honey” cannot distinguish the requesting human's
agent from another owner's agent, and the owned match can be excluded by
the result limit. This caused the wrong Honey and Bumble pubkeys to be
added to a channel.

## Summary

This bug fix makes personal-agent resolution owner-aware. Callers can
filter profiles by a verified owner identity before result limits are
applied, and all profile results expose enough ownership context to
diagnose duplicate names.

## Changes

- Adds `buzz users get --owner me|<hex>|<npub>` for name and pubkey
lookups.
- Resolves `me` to the NIP-OA owner identity when the CLI runs as an
agent.
- Filters profiles by the relay's verified `agent_owner_pubkey`
relationship before applying the result limit.
- Returns `owner_pubkey`, `owner_display_name`, and client-relative
`owned_by_me` in compact and JSON output.
- Returns an empty result when no owned profile matches instead of
removing the ownership constraint.
- Rejects malformed owner values instead of silently running an unscoped
query; explicit `null` remains equivalent to no owner filter for
ordinary CLI lookups.
- Rejects owner constraints on specialized channel-window, feed, and
thread filters that cannot enforce author filtering.
- Scopes owner filtering and enrichment to the active community.
- Adds a partial `(community_id, agent_owner_pubkey)` index for owner
lookups.
- Documents the safe `users get --name Honey --owner me` lookup.

## Reviewer-reproducible examples

The relay-backed test creates two same-name agents with different
verified owners, queries through the HTTP `/query` route, verifies only
the selected owner's agent is returned with verified owner metadata, and
verifies a missing owner returns `[]`.

```bash
cargo test -p buzz-relay query_agent_owner_returns_only_verified_owner_matches --lib -- --ignored
```

The owner/author intersection and unsupported-specialized-filter
contracts also have infrastructure-free relay tests:

```bash
cargo test -p buzz-relay agent_owner --lib
```

The CLI surface is visible in command help:

```bash
cargo run -q -p buzz-cli -- users get --help | grep -- --owner
```

```text
      --owner <OWNER>     Filter agents by verified owner (`me`, 64-char hex, or npub)
```

## Validation

- `cargo test -p buzz-cli` (252 passed)
- `cargo test -p buzz-db` (84 passed, 122 infrastructure tests ignored)
- `cargo test -p buzz-relay --lib` (owner-filter tests pass; the full
local suite is blocked by unrelated Postgres pool timeouts in
media/admin tests)
- `cargo test -p buzz-relay
query_agent_owner_returns_only_verified_owner_matches --lib --
--ignored` (passed)
- `cargo check --workspace --all-targets`
- `cargo fmt --all -- --check`
- Pre-push Rust, Desktop, and Desktop Tauri suites passed
- Pre-push mobile suite could not start because `flutter` is not
installed
- `pnpm check:file-sizes` (passed after rebasing onto current `main`)

relay-admin kinds **9030–9033**, so that a *timed-out* admin keeps
administrative capability. That exemption was ban-blind, and
`handle_relay_admin_event` performed no restriction check of its own. A
**banned** admin or owner could still add members, remove members,
change member roles, and set the workspace icon by posting a signed
NIP-98 request to `POST /events`. No open WebSocket required.

Reported externally by **Bilal Syed** (also filed publicly as #3020
before he read `SECURITY.md`). Verified true, reproduced live, and found
slightly worse than reported.

Same class as BUZZ-SEC-007, which PR #1915 closed for moderation command
kinds 9040–9044. That fix was never extended to the 9030 range.

## Why it worked

- `handlers/ingest.rs:1639` skipped the restriction check when
`is_relay_admin_kind(kind)` was true.
- `handlers/relay_admin.rs` did a freshness check and a role lookup only
— zero restriction reads in the file.
- A ban does not remove the role: `ban_member`
(`buzz-db/src/moderation.rs:314`) writes only `community_bans`, so the
`relay_members` admin row survives.
- The HTTP path never consulted ban state — `enforce_relay_membership`
is a bare `SELECT 1 FROM relay_members`.
- The ban was enforced only at the NIP-42 auth seam, which an HTTP
request never crosses.

**Worse than reported:** the report covered remove (9031) and icon
(9033). Add (**9030**) works too, so a banned admin can *plant* new
members. That matters because `moderation_authz.rs:163-170` derives "an
admin cannot ban an owner or fellow admin" from `relay_members` — the
very table 9030/9031 mutate. A banned admin could seed accomplices into
the roster the ban was meant to stop them touching.

Also of note: `moderation_authz.rs:158-165` already asserts in a comment
that *"The command handler separately rejects a banned actor on every
transport."* `relay_admin.rs` was the one command handler not holding
that invariant.

## The fix

Enforce the durable ban **inside `handle_relay_admin_event`** — the
reporter's own suggested shape, and the `moderation_commands.rs:99-108`
precedent.

Deliberately **not** the one-token alternative of dropping `&&
!is_relay_admin_kind(kind_u32)` at `ingest.rs:1639`: that would also
start blocking *timed-out* admins, silently changing policy. Bans are
refused; timeouts still administer, which is the entire reason the
exemption exists.

`handle_relay_admin_event` becomes a thin admission wrapper around an
unchanged `execute_relay_admin_command` body, so no future early return
inside that body can precede the check. The check therefore also
necessarily precedes the freshness check.

**The refusal category is part of the security contract**, so this
returns a typed `RelayAdminError` rather than a string. A `blocked:`
string would have kept the right wire text but returned **400** instead
of **403** (`api/bridge.rs:845` vs `:858`), and would have reported a
restriction-DB outage as a client error:

| Variant | Ingest | Wire | HTTP |
|---|---|---|---|
| `Banned` | `AuthFailed` | `blocked: you are banned from this
community` | **403** |
| `Rejected(..)` | `Rejected` | `invalid: …` | 400 (unchanged) |
| `Internal(..)` | `Internal` | `error: …` (sanitized) | **500** |

## Verification

Live over real HTTP against an isolated relay, all four exempt kinds
refused, DB checked after each for non-mutation:

```
[banned] 9031 remove      -> 403 blocked: you are banned from this community
[banned] 9030 add         -> 403 blocked: you are banned from this community
[banned] 9032 change role -> 403 blocked: you are banned from this community
[banned] 9033 set icon    -> 403 blocked: you are banned from this community
```

Victim still `member`, planted key absent, role target unchanged, icon
still NULL. 9032 required a banned **owner** to be a real test, since it
is owner-only.

- **Mutation-tested.** The admission decision is the pure
`admits_relay_admin_command(&RestrictionState)`, covered by the
*default* suite. Neutering it fails
`banned_actor_is_not_admitted_to_a_relay_admin_command`. The first
version of this patch would have stayed green if someone deleted the
check — that gap is closed. The unit test does not prove handler
*wiring*; the `#[ignore]`d live E2E is what checks linkage.
- **Fail-closed proven empirically**, by manual fault injection rather
than assertion: renaming `community_bans.banned` out from under the
running relay yields 500, no mutation, and no schema detail leaked to
the client.
- Negative/positive controls: timed-out admin still administers *and* is
still content-write-blocked; clean admin unaffected with mutation
confirmed; non-admin still gets `invalid:`/400.
- Reviewed iteratively by **@Mari** over three rounds; final approval at
9/10+ on minimalness, elegance, and correctness. She also ran an
independent deep regression pass on an isolated stack (odd port 44391)
covering channel lifecycle, membership,
messages/replies/search/edit/delete, reactions, canvas, DMs, and
moderation transitions — no regressions.
- `cargo fmt --all --check`, `cargo clippy -p buzz-relay --all-targets
-D warnings`, `buzz-core` 229/229, `buzz-cli` 250/250, `run-tests.sh
unit` all five packages green.
- `buzz-relay --lib`: **756 passed / 1 failed**. The sole failure
`api::mesh_demo::tests::demo_join_forwarded_arm_round_trips_echo` (504
vs 200) is **pre-existing** — reproduced identically in a detached
worktree at merge base `00ecf2c`.

## Notes for the reviewer

- Merged `origin/main` in as a merge commit rather than rebasing, per
instruction. No conflicts; the eight incoming commits touch none of the
three files here. Closest neighbour is `00ecf2c` (kind:9000 NIP-29
*channel* role authz) — disjoint from this NIP-43 *relay-admin* fix.
- **This does not close the class.** Two separate items remain open,
deliberately excluded to keep an externally-known security fix
reviewable:
1. **Command kinds dispatch before the gate.** `is_command_kind` fires
at `ingest.rs:1561`, ~80 lines *before* the restriction gate, and
`command_executor.rs` has no restriction read. Measured live: a banned
member can still open a DM (41010 → 200). 41011/41012/30620/46030/46031
unprobed. Needs per-kind semantics enumerated first (reports allowed
while banned; moderation commands allow timeouts but reject bans;
ordinary writes reject both).
2. **`moderation_commands.rs` maps its own restriction-DB failure to
400, not 500**, and leaks the raw Postgres message to the client.
- One correction for the public issue: its repro step 1 says
`kind:9041`, which is **unban**. The ban is **9040**
(`KIND_MODERATION_BAN`, `buzz-core/src/kind.rs:298`). Following the
steps verbatim yields a false negative.

00ecf2cac7 fix(security): authorize kind:9000 role changes in both directions (#3017)
## Summary

NIP-29 `kind:9000` (PUT_USER) role changes were only authorized when the
**new** role was elevated. Demotions were unauthorized, so any
authenticated user could strip a channel owner to `member` with a single
event — and the demotion was unrecoverable, since the ex-owner then
lacked the privilege to restore themselves.

Reported by @Tyler in `#buzz-security`. Verified true, plus two adjacent
defects the report flagged and one it did not.

## The defects

1. **Demotion unauthorized.** The actor check only fired when the
*requested* role was elevated. Lowering someone's role skipped it
entirely.
2. **Open channels skipped the actor check.** It was nested under
`visibility == "private"`.
3. **`add_member` had no last-owner guard** while `remove_member` did —
so a channel could be left with zero owners.
4. **(Not in the report.)** An absent `role` tag defaulted to `Member`,
so a bare self-targeted PUT_USER silently demoted the sender. No
attacker required.

## The fix

**`crates/buzz-db/src/channel.rs`** — the authority, because it also
covers the desktop/admin callers that bypass the relay validator:

- Changing an **active** member's role requires an elevated actor **in
both directions**. Re-adding at the same role stays unguarded and
idempotent (the huddle bot-add and `kind:9021` join paths depend on
this).
- Last-owner guard in `add_member`, mirroring `remove_member`.
- Keyed on the **active** role (`removed_at IS NULL`). A soft-removed
row's role is history, not live authority — otherwise soft-deleted
ownership becomes a resurrection token: a kicked owner self-rejoins via
`9021` and silently regains ownership.
- New `pg_advisory_xact_lock` on a channel-membership namespace, taken
as the first statement in both `add_member` and `remove_member`. Both
read an owner `COUNT` and then write a *different* row, so READ
COMMITTED alone lets two concurrent demotions each observe 2 owners and
together leave 0.
- `remove_member`'s `is_agent_owner` lookup moved before the transaction
opens — it borrows a second pool connection, and issuing it while
holding the lock could self-deadlock on a small pool. Safe because
`agent_owner_pubkey` is immutable (first-mint-wins).

**`crates/buzz-relay/src/handlers/side_effects.rs`**:

- Role tag is now `Option` — absent means "no role change requested"
rather than defaulting to `Member`.
- Actor-role lookup hoisted out of the `visibility == "private"` block,
so open channels are covered.
- Role-change and last-owner guards on every visibility. Rejecting here
*as well as* in the DB means clients get a real error instead of an `OK`
whose side effect then fails silently.

## Verification

**Mutation tested — every guard stubbed individually to confirm a test
actually dies.** Three of eight guards were originally uncovered and
survived being disabled with the suite fully green:

| Guard | Dying test |
|---|---|
| DB actor-auth | *survived* → **new**
`unprivileged_member_cannot_demote_a_co_owner` |
| DB last-owner | `owner_can_still_manage_roles_after_demotion_guard` |
| DB active-role (soft-remove) |
`kicked_owner_rejoins_as_member_not_owner` + 3 |
| `add_member` advisory lock |
`membership_writes_serialize_on_the_shared_channel_lock` |
| `remove_member` advisory lock | +
`remove_member_rejects_an_actor_demoted_while_it_waited` |
| relay no-role-tag preservation |
`test_nip29_put_user_without_role_tag_preserves_role` |
| relay actor-auth | *survived* → **new**
`test_nip29_relay_rejects_role_change_by_unprivileged_actor` |
| relay last-owner | *survived* → **new**
`test_nip29_relay_rejects_last_owner_self_demotion` |

The three gaps shared one cause: every existing test asserts resulting
**state** ("the role did not change"), and the DB guards enforce that
state, masking every layer above them. With a relay guard stubbed the
relay answers `accepted:true` and logs `Side effect failed: access
denied: ...` while the state assertion still passes — the entire relay
validator could be deleted unnoticed. The new relay tests assert
`accepted == false` instead, the one observable only the validator
controls. Each new test is verified in both directions: green against
the real fix, failing with its intended message when its guard alone is
stubbed.

**Test runs** (at `9461eedb`):

- `buzz-db`, serial: **210 passed / 3 failed** — the same 3 failures as
clean `main` (202/3), which are pre-existing and unrelated
(`concurrent_same_owner_create…`,
`create_community_with_owner_is_atomic…`,
`test_usage_metrics_lock_has_single_owner…`). +8 = the new tests.
- `e2e_relay --ignored`: **40 passed / 3 failed**. Clean `main` on the
same relay is 35/6 — the same 3 infra failures
(`test_invite_mint_and_claim…`, `test_subscription_limit_enforced`,
`test_unarchive_emits_member_added_notification`) plus the 3 security
tests that fail unpatched and pass here.
- `cargo fmt`, `clippy`, `git diff --check` all clean.

**Live manual drive** against a locally running relay, using raw
`nak`-signed events (the `buzz` CLI refuses malformed `kind:9000`, so
the guards have to be exercised directly):

- *Rejected:* member demotes owner; member demotes admin; self-promote
to owner; self-promote to admin; admin demotes the last owner; sole
owner self-demote; demoted ex-owner demotes last owner; private-channel
member demotes owner; non-member demotes owner in private.
- *Allowed:* bare PUT_USER with no role tag (owner keeps role);
idempotent re-add at same role; owner promotes admin→owner, then owner2
legitimately demotes owner1.
- *Resurrection defeated:* owner promotes attacker to admin → kicks them
(`9001`) → attacker self-rejoins (`9021`) → returns as **member**, not
admin, and cannot demote the owner.
- Normal ops unaffected throughout: channel creation, messaging, member
listing, and legitimate governance all work.

## Behavior change to be aware of

Huddle bot-add sends `role="bot"`. If the target is **already an active
member at a different role**, that is now a role change and requires an
elevated actor. Previously it silently re-roled them — the same privesc
primitive through a different door, so narrowing it is intended.

This does not break the huddle flow in the path that matters: the
ephemeral channel add (the one that fails hard) is performed by the
host, who *created* that channel and is therefore its owner — verified
live. The parent-channel add is already explicitly best-effort,
capturing the error into `parent_error` with a comment anticipating "may
already be member"; adding a non-member agent there still works.
Flagging it rather than burying it.

## Notes

- Commit is **signoff-only, not cryptographically signed** — `-S` fails
in this environment (git tries to load the agent npub as an SSH key
file). DCO trailers are present and correct.
- Branch was merged with `origin/main` via `--no-ff` (not rebased).
Upstream had 17 commits, none touching these files, no migration
changes.

ab3af82871 feat(relay): add author-only-unless-shared read gate for kind 30175 (#2768)
Kind 30175 persona sync events carry plaintext `system_prompt` and
`respond_to_allowlist`. This PR adds **author-only-unless-shared read
semantics**: events without `["shared","true"]` are visible only to the
author; events with that tag are community-readable.

## What changed

### New read class (kind 30175)
Kind 30175 gets per-event gating at every relay read surface. The
`shared` marker is a **tag**, not a content field, so content bytes
(which double as the `source_version` drift basis) are not affected when
toggling share state.

### `event_visible_to_reader` helper (`handlers/req.rs`)
Centralizes the three per-event access predicates —
`is_author_only_event`, `is_unshared_persona_event`,
`reader_authorized_for_event` — into one `pub(crate)` fn callable from
both WS and HTTP adapters. All result-visibility sites now call this
single helper.

### NIP-98 HTTP bridge (`api/bridge.rs`)
- `POST /query` catchall: replaced the two-step author-only +
result-gated checks with `event_visible_to_reader` (now also covers the
persona shared-gate).
- `POST /count`: added `needs_persona_filtering` to the fast-path guard
(forces per-event fallback when filter can match `kind:30175`) and
replaced both fallback loops' individual checks with
`event_visible_to_reader`.
- FTS `/search` bridge helper: replaced `is_author_only_event` with
`event_visible_to_reader` as defense-in-depth (30175 is not in the FTS
allowlist today; comment at site explains the future-proofing intent).

### Ingest validation (`handlers/ingest.rs`)
`validate_persona_envelope` rejects malformed `shared` tags: wrong
value, missing value, duplicates. Accepts exactly `["shared","true"]`
and tag-absent.

### Kind helpers (`buzz-core/src/kind.rs`)
`is_persona_shared_kind`, `is_unshared_persona_event`,
`filter_can_match_persona_shared_kinds`.

### Tests (`e2e_persona.rs`)
8 unit tests in `kind.rs`, 6 in `ingest.rs`, 8 e2e tests total:
- AC-1–6 covering the gated surfaces
- `test_persona_live_fanout_shared_gate`: reworked with explicit
monotonic `created_at` timestamps (t0 < t1 < t2) and per-step head
assertions, eliminating the NIP-33 event-id tie-break race. Also asserts
foreign live subscription receives nothing on shared→unshared
transition.
- `test_persona_ingest_shared_tag_validation`: added `shared=x` and
missing-value wire-level rejection cases.
- `test_persona_mixed_kind_filter_does_not_leak`: publishes a kind-9
event and asserts it IS returned; absence-only assertion no longer
sufficient.
- `test_persona_http_query_cross_author_gate`: NIP-98 `/query`
cross-author gate (authors filter, kindless `ids` — both blocked; shared
`ids` — passes).
- `test_persona_http_count_cross_author_gate`: NIP-98 `/count`
cross-author gate (foreign sees 1/shared, author sees all, wildcard
checked).

### NIP-AP.md
Replaced aspirational "every relay read chokepoint" wording with an
enumerated list of gated surfaces including NIP-98 `/query`, `/count`,
and FTS/search with their enforcement mechanism named. Added
**Non-goal** note for side-band existence oracles
(reaction/report/deletion target resolution).

## Existing tests
All pre-existing `e2e_persona` tests use `{ids:[event_id]}` or
`{authors:[self]}` filters — author self-reads bypass the gate and are
unaffected.

## Gates
`just check`  | `just test-unit`  | `cargo test -p buzz-relay`  (749
passed, 1 pre-existing failure in
`demo_join_forwarded_arm_round_trips_echo` — flaky on `main`, unrelated
to this PR, verified red at `origin/main` before this branch)
