53771c8f54 fix(acp): preserve truncated thread context (#3340)
## Why
Long Buzz threads were rendered as `[Thread Context (13 of 13
messages)]` because the harness counted only the already-limited query
result. That hid older context and could also hide the agent's own prior
reply in busy threads.

## What
- Fetch one extra thread reply as a sentinel so truncated context is
labeled correctly.
- Use a best-effort `/count` call for improved truncated totals when
available, clamped to the sentinel-proven minimum so racy counts cannot
render impossible labels.
- Keep the `/count` path single-attempt with a short timeout and only
add the root to exact totals when the root was actually fetched.
- Fetch and preserve the agent's newest prior reply when it falls
outside the recent window, with exact event-id matching for the
pin/dedup boundary.
- Add parser and fetch-boundary tests for truncation, exact count,
missing root, count-below-minimum clamping, count failure fallback,
distinct fetched-reply lower bounds, agent-reply dedup/pinning, and
serialized query/count filter semantics.

## Risk Assessment
Low-to-medium — limited to buzz-acp prompt context fetching and a small
RestClient helper. If `/count` fails or times out, the code falls back
to the sentinel-derived minimum total rather than failing the prompt.
The synchronous `/count` happens only for truncated thread contexts and
is bounded to one short best-effort attempt.

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).

262f2392e3 fix(cli): resolve agents from owner records (#3178)
## Context

`buzz users get --name Honey` searches relay-wide profiles and can
return an identically named agent owned by someone else. This caused
agents from the wrong owner to be added to a channel.

## Summary

This bug fix scopes exact-name agent lookup to owner-authored
managed-agent records, then cryptographically verifies each returned
profile's NIP-OA `auth` tag before asserting ownership. The relay and
database contracts remain unchanged.

### Related issue

None found.

## Changes

- Adds `buzz users get --name Honey --owner me|<hex>|<npub>`.
- Resolves `me` to the NIP-OA owner when the CLI runs as an agent,
otherwise to the CLI identity.
- Matches kind `30177` managed-agent record names exactly and
case-insensitively under the requested owner.
- Requires exactly one valid NIP-OA `auth` tag whose verified owner
equals the requested owner and whose `kind` and `created_at` conditions
apply to the profile event before returning `owner_pubkey` or
`owned_by_me: true`.
- Keeps missing, malformed, stale, condition-mismatched, or unverifiable
owner-record candidates visible with `owned_by_me: false` and an
explicit `verification` value.
- Returns every same-name record for the owner so callers can require
explicit selection when duplicates remain.
- Preserves the existing output shape and client-side name filter for
unscoped searches.
- Documents the distinct owner-scoped managed-agent lookup and unscoped
NIP-50 lookup modes.

### Testing

The reviewer-reproducible red and green commands below exercise the
ownership bug against the target branch and this branch.

## Screenshots

Not applicable. This is a CLI-only change.

## Reviewer-reproducible examples

The lookups below were run against the live relay from `main` and this
branch.

### Red: unscoped lookup returns the 100-profile relay-wide cap and
excludes John's agents

On `main`:

```bash
cargo run -q -p buzz-cli -- users get --name Honey \
  | jq '{count: length, first_three: .[:3] | map(.pubkey), johns_agents: map(select(.pubkey == "31b29bcbe69d6716fbb7ba33602b89200bfc9ddfdabcfd1ea6fbfa70b816dfc7" or .pubkey == "4597ac725bba33fc7dd0454c1e2316a5ed770426acf667837d46f6553b3fcf54"))}'
```

Observed output:

```json
{
  "count": 100,
  "first_three": [
    "20d27fc6c0ab4f50b66d1a32a64c5ca1fb985254143ce911f61ab7733333c3d7",
    "00644478cdd9032c563ddc712b3687d8345d948945aab3c18bab95afbf6f519a",
    "93c16697d0e58007bc11fb953208bc6b1cff387b2dee094abc10bf82dfee5424"
  ],
  "johns_agents": []
}
```

`main` also rejects the owner-scoped command:

```bash
cargo run -q -p buzz-cli -- users get --name Honey --owner me
```

```text
error: unexpected argument '--owner' found
Usage: buzz users get --name <NAME>
```

### Green: owner-scoped lookup distinguishes verified and unresolved
records

On this branch:

```bash
cargo run -q -p buzz-cli -- users get --name Honey --owner me \
  | jq 'map({pubkey,display_name,owner_pubkey,owned_by_me,verification})'
```

Observed output:

```json
[
  {
    "pubkey": "0ca77314d7ac8b3fcf6c647cc8cb9c3afd840db3b2a8ff2079f09a168de1827e",
    "display_name": null,
    "owner_pubkey": null,
    "owned_by_me": false,
    "verification": "missing_profile"
  },
  {
    "pubkey": "31b29bcbe69d6716fbb7ba33602b89200bfc9ddfdabcfd1ea6fbfa70b816dfc7",
    "display_name": "Honey",
    "owner_pubkey": "67252b09c31a995daa63aada26569fbc6a3d12f573113f001ce7432f870da820",
    "owned_by_me": true,
    "verification": "verified"
  },
  {
    "pubkey": "4597ac725bba33fc7dd0454c1e2316a5ed770426acf667837d46f6553b3fcf54",
    "display_name": "Honey",
    "owner_pubkey": "67252b09c31a995daa63aada26569fbc6a3d12f573113f001ce7432f870da820",
    "owned_by_me": true,
    "verification": "verified"
  }
]
```

Only the two profiles with valid NIP-OA proofs assert ownership. The
owner-authored record whose profile is absent remains visible but cannot
be selected as verified ownership.

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.aws.amazon.com/AmazonS3/latest/userguide/VirtualHosting.html
- https://docs.rs/rust-s3/0.37.0/s3/bucket/struct.Bucket.html
- 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

ab55fee818 feat: add first-class OpenRouter provider support (#1975)
## Summary

First-class `Provider::OpenRouter` support joining the existing
anthropic/openai/databricks providers. Reuses the Chat Completions path
with targeted mutations for OpenRouter's routing contract.

**Core (`crates/buzz-agent`):**
- `Provider::OpenRouter` enum variant with `OPENROUTER_API_KEY`,
`BUZZ_AGENT_MODEL` → `OPENROUTER_MODEL` fallback, `OPENROUTER_BASE_URL`
env convention
- Body mutator: `reasoning: {effort}` when effort is configured, and
`max_completion_tokens` translated to OpenRouter's `max_tokens`
spelling; no `provider.require_parameters` filter (it routes only to
endpoints advertising every parameter in the body, which hard-404s a
valid model id); summaries get neither. `openai_body` is always called
with `effort=None` on the OpenRouter path — the `reasoning` object is
added by the mutator directly, so `reasoning_effort` is structurally
absent.
- Attribution headers: `HTTP-Referer: https://github.com/block/buzz`,
`X-OpenRouter-Title: Buzz`
- Error-inside-200 check in shared `parse_openai` (`finish_reason ==
"error"`)
- 401 auth handling: static API keys (`refresh_now` returns the same
token) fail terminal immediately with one wire request; PKCE/minting
sources get one retry with the fresh token.
- Status+`error_type` retry matrix (4-arm collapsed form): 429 (honor
`Retry-After`), 502 (retry), 503/`provider_overloaded` (honor
`Retry-After`), everything else including untyped 503 (bounded retries →
actionable routing message). 499 included matching shared `post()`
(#2175) for turn-timeout stall surfacing. Terminal failures wrapped in
`terminal_llm_error` for duration+attempt-count context.
- `anthropic/*` `cache_control` injection (model-gated, mixed-content
safe)
- Provider-agnostic `reasoning_details` opaque round-trip on
`HistoryItem::Assistant` for tool-call continuations — captured verbatim
in `parse_openai_with_reasoning_details`, replayed verbatim in
`openai_body`, byte-accounting charged. `provider_extra` passthrough
from `make_tool_call` composes independently.

**Desktop:**
- Readiness arms checking `OPENROUTER_API_KEY` + `OPENROUTER_MODEL`
- Model discovery via `{OPENROUTER_BASE_URL}/models` filtered on
`supported_parameters` contains `tools`
- Picker entry, credential config, effort table 3-file sync

**`desktop/src/features/agents/AGENTS.md`: no rules changed** — the
scoped rule requiring an explicit note is satisfied here.

Implements the gate-cleared plan from
`PLANS/OPENROUTER_PROVIDER_PLAN.md` (rev 3).

f95fdc1a10 feat(agent,acp): wire provider total_tokens through NIP-AM publish chain (#3593)
## What

Wires genuine provider-reported `total_tokens` through the full
buzz-agent → buzz-acp publish chain so kind-44200 events carry real
per-turn and cumulative totals for OpenAI-backed models, while
preserving all existing behaviour for Anthropic and external harnesses
(goose, claude-code).

## Why

Live prod data showed 0 of 1,934 archived reports carry `totalTokens`.
Both hardcoded `total_tokens: None` in `pool.rs` and the absent field in
`buzz-agent`'s parser are root causes. This is the backend half of a
two-track fix; the display-fallback half lands in
[#2035](https://github.com/block/buzz/pull/2035).

## Changes

**`crates/buzz-agent/src/types.rs`**
- Added `total_tokens: Option<u64>` to `LlmResponse` with an explicit
doc comment that NIP-AM forbids deriving it.
- Added `TurnTotalState` enum (`Unseen | Exact(u64) | Unknown`) with
`fold()` and `exact_value()` — the tri-state accumulator that
distinguishes not-yet-observed from permanently poisoned.

**`crates/buzz-agent/src/llm.rs`**
- `parse_responses` and `parse_openai`: read `usage.total_tokens` from
OpenAI Chat Completions (including Databricks routes) and the Responses
API via `sum_usage`.
- Anthropic: explicit `total_tokens: None` — no genuine total available;
NIP-AM forbids summing categories.

**`crates/buzz-agent/src/agent.rs`**
- Added `turn_total_state: &'a mut TurnTotalState` to `RunCtx`.
- Fold `response.total_tokens` into the accumulator after each
usage-bearing response; non-usage-bearing responses (keepalive/stream
frames) do not poison.

**`crates/buzz-agent/src/lib.rs`**
- Added `accumulated_total_state: TurnTotalState` to `Session` (default
`Unseen`).
- Per-turn state passed to `RunCtx`, folded into session cumulative
after each turn.
- Emits `accumulatedTotalTokens` in `usage_update` only when cumulative
is `Exact(n)`.

**`crates/buzz-acp/src/usage.rs`**
- Added `accumulated_total_tokens: Option<u64>` (serde default) to
`UsageUpdatePayload` — optional for goose compat.
- Added `last_total: Option<u64>` to `SessionState`.
- Added `turn_total_tokens` and `cumulative_total_tokens` to `TurnUsage`
(field-local — never affect `delta_reliable`).
- Derive turn-total delta only when prev and current are both `Some` and
monotonic; absence, decrease, or no baseline leaves only the total delta
null without touching input/output reliability.

**`crates/buzz-acp/src/pool.rs`**
- Replaced both hardcoded `total_tokens: None` in
`publish_agent_turn_metric` with `usage.turn_total_tokens` and
`usage.cumulative_total_tokens`.

## Tests

20 new tests across the four touched files:

| File | Tests |
|------|-------|
| `types.rs` | `TurnTotalState` fold, accumulation, exact_value, default
(7 tests) |
| `llm.rs` | Chat present/absent, Responses present/absent, Anthropic
always-None (5 tests) |
| `usage.rs` | First turn no baseline, second-turn delta, cumulative
decrease (field-local), current absent, goose-shaped deserialization,
baseline absent (6 tests) |
| `pool.rs` | Exact turn+cumulative mapping, null totals never derived
(2 tests) |

`cargo test -p buzz-acp -p buzz-agent` — all passing, 0 failures.

## Scope

Boundary: `crates/buzz-agent/**` + `crates/buzz-acp/**` only. Desktop
unchanged.
`costUsd` explicitly out of scope.

7adc46268d feat(cli): mirror Desktop mention delivery (#3330)
🤖
## Summary

Agent-authored mentions currently depend on matching visible `@Name`
text to channel profiles. That makes notification delivery ambiguous
when names collide or profiles change, and it encourages an extra
post-send lookup just to confirm that the intended `p` tags were
emitted.

This change makes `buzz messages send` mirror Desktop's existing model:
the message keeps a readable name in its content while the recipient
pubkey is supplied separately.

```bash
buzz messages send \
  --channel <UUID> \
  --content '@Alice could you review this?' \
  --mention <alice-hex-or-npub>
```

`--mention` is repeatable. The CLI normalizes and deduplicates explicit
pubkeys, merges them with any names it can resolve from the channel, and
gives explicit identities priority under the existing 50-mention limit.

Before uploading attachments, signing, or publishing, the command checks
every resulting pubkey against the channel's current membership:

- Members are mentioned normally.
- Non-members stop the send and produce an actionable error.
- `--allow-non-member-mentions` deliberately sends notifying `p` tags
without adding anyone to the channel.

Sending a message never changes membership. On success,
`mention_pubkeys` is read from the exact signed event and returned with
the relay response, so callers can verify the emitted recipients without
another query.

Managed-agent guidance teaches this single-command mention flow. Desktop
mention behavior and the Nostr event schema are unchanged. Forum
guidance is intentionally handled separately in #3596.

### Related issue

None found. This replaces the earlier guidance-only approach in this PR
with the underlying CLI behavior it required.

### Testing

- `cargo test -p buzz-sdk`
- `cargo test -p buzz-cli`
- `cargo test -p buzz-acp`
- `cargo test --manifest-path desktop/src-tauri/Cargo.toml`

Will PflegerandGitHub ddd468723a revert(acp): remove dead GOOSE_ACP_SCHEDULER_DISABLED env injection (#3576)
## Summary

[block/buzz#3144](https://github.com/block/buzz/pull/3144) injected
`GOOSE_ACP_SCHEDULER_DISABLED=true` into every `AcpClient::spawn` call
as a forward-compatible no-op, intended to suppress the cron scheduler
in goose ACP children once the matching reader landed in goose. That
reader only ever existed in
[aaif-goose/goose#10738](https://github.com/aaif-goose/goose/pull/10738),
which was closed unmerged.

[goose#10781](https://github.com/aaif-goose/goose/pull/10781) (Lifei
Zhou, merged 2026-07-29) disables the ACP scheduler by default at the
source: `goose acp` now requires `--enable-scheduler` to start a
scheduler. Buzz-spawned children therefore get no scheduler with zero
configuration — making the `GOOSE_ACP_SCHEDULER_DISABLED` injection
permanently dead code.

## What changes

Removes from `crates/buzz-acp/src/acp.rs`:

- `GOOSE_SCHEDULER_DISABLED_ENV` constant
- `cmd.env(GOOSE_SCHEDULER_DISABLED_ENV, "true")` injection in
`AcpClient::spawn`
- `spawn_injects_scheduler_disabled_env_by_default` test
- `spawn_scheduler_disabled_env_overrides_conflicting_extra_env` test
- `spawn_and_read_child_env` helper (unreferenced once the two tests
above are gone)

No other files are affected.

## Why now

Leaving dead code that references an env var no reader will ever consume
misleads future maintainers about the actual scheduler-isolation
mechanism. The isolation is now an upstream default, not a Buzz
injection.

4a1ebf25c7 feat(agent): make Gemini and MLflow-route models usable through databricks_v2 (#3569)
## Summary

Makes Gemini — and every other non-Claude, non-GPT-5 model on the
Databricks MLflow route (`databricks_v2`) — usable in an agent loop.
These are the non-`benchmarks/` changes from
`benchmark/harness-accounting-and-solo`, lifted onto a clean base off
`main` so they can land independently while the harness work continues.

Two defects made these models unusable, one fatal and one silent. Both
live only in `openai_body` / `parse_openai`, which is the
least-exercised of the three `databricks_v2` sub-routes — the
`luna`/`sol` conditions run the Responses route and the `opus`
conditions run the Anthropic route, so **this change is inert for every
model already in use** and only lights up the MLflow path.

## Why a third route at all

`databricks_v2_route_for_model` buckets by model family: `claude*` →
Anthropic Messages, `gpt-5`/code-names → OpenAI Responses, **everything
else → MLflow chat-completions**. Gemini, Qwen, gpt-oss, and friends all
fall through to that third pair — and both bugs below live only there.

## D1 — dropped thought signatures (fatal)

Gemini returns a `thoughtSignature` on every tool call and **requires it
echoed back**. `openai_body` reserialized each call as `{id, type,
function}` only, dropping the field, so the next request 400'd:

```
HTTP 400  Function call is missing a thought_signature in functionCall parts.
```

For a coding agent this fires on the **first** tool call, so the model
never completes a single turn.

**Position is load-bearing.** A four-shape replay probe against the live
gateway established that the signature must sit as a *sibling* of
`function` — nesting it inside `function{}` fails with the *same* 400 as
omitting it. A fix that "preserves the field" without preserving its
position passes a unit test and still 400s.

The fix: `ToolCall` gains `provider_extra: Map<String, Value>`.
`parse_openai` captures every top-level wire key except the three we
model (`id`, `type`, `function`); `openai_body` re-emits them beside
`function`. Keeping *whatever we did not model*, rather than naming
`thoughtSignature`, means the next provider with an opaque per-call
token needs no change here. The Responses and Anthropic replay shapes
are fully modelled, so they pass `Default::default()` and stay
**byte-identical** to before.

### D1b — duplicate tool-call ids (same root cause)

Gemini returns the **function name** as the id, so two parallel calls to
one function arrive sharing an id — and that id is what pairs a
`role:"tool"` result back to its call, making two results
indistinguishable. `dedupe_provider_ids` suffixes collisions
(`get_weather`, `get_weather-2`). Safe because both halves of the
pairing (the assistant `tool_calls[].id` and the result's
`tool_call_id`) are re-emitted from this same value; the provider never
sees its original id again.

## D2 — block-array content discarded (silent, worse than a crash)

`parse_openai` read `content` with `as_str()`, which returns `""` for
anything that isn't a JSON string. Gemini (and Qwen35, gpt-oss) send an
array of typed blocks:

```json
"content": [
  {"type": "reasoning", "summary": [{"type": "summary_text", "text": "…"}]},
  {"type": "text", "text": "391"}
]
```

So the model answered and the answer was thrown away — no error, no
warning, just a turn that looked like the model had said nothing. On a
benchmark this reads as "Gemini is bad at the task" rather than "buzz
dropped the reply."

`openai_content_parts` now accepts either shape — string as before, or a
block array where `text` blocks concatenate into text and `reasoning`
blocks into reasoning (Gemini nests the prose one level down under
`summary`). Message-level `reasoning_content` / `reasoning` still win
when present, so DeepSeek and vLLM-style hosts are unchanged; block
reasoning is the last fallback.

## Also: a turn-start log line (`buzz-acp` `pool.rs`)

Small, independent observability change that also rides in the
non-benchmark delta: `run_prompt_task` now emits a `pool::prompt` "turn
starting" line, labelled by the same `prompt_label` helper as
`log_stop_reason`, so a log reads as start/stop pairs. An unpaired start
is the only durable evidence that a turn was entered and never returned
— without it, a stalled agent and an agent nobody woke leave identical
(zero-completion) logs.

## Interaction with #3538

#3538 (already merged) rewrote `databricks_v2_route_for_model` to route
by boundary-aware model-family segments. That change and this one touch
**different functions** in `llm.rs` — routing vs. body/parse — and
compose cleanly; the family routing decides *which* pair runs, and this
fixes the MLflow pair it can now select.

## Testing

- `cargo fmt --all -- --check`, `cargo clippy -p buzz-agent -p buzz-acp
--all-targets -- -D warnings` — clean.
- `cargo test -p buzz-agent -p buzz-acp` — all green (304 + 632 lib
tests plus integration suites, 0 failures). Five new tests cover:
block-array text extraction, plain-string regression, passthrough
capture (and non-duplication of the modelled keys), replay position
(`thoughtSignature` beside `function`, not inside it), and id
de-duplication.
- Wire evidence: the four-shape replay table and the reasoning-effort
probe were run against `block-lakehouse-staging` (recorded in the design
doc).

## Relationship to the benchmark branch

The full design write-up (four-shape replay table, position-matters
analysis, effort verification, and open pricing item) lives in
`docs/08-gemini-provider-fixes.md` on
`benchmark/harness-accounting-and-solo`. The benchmark manifests and
endpoint-config entries that exercise these models are separable and
stay on that branch.

9beb3b8c6e fix(cli): mask credential env values in --help output (#3570)
clap renders live env var values in help text by default. Three args
carrying credentials were exposed this way:

- `BUZZ_PRIVATE_KEY` in `buzz-cli` (`crates/buzz-cli/src/lib.rs`)
- `BUZZ_AUTH_TAG` in `buzz-cli`
- `BUZZ_PRIVATE_KEY` in `buzz-acp` (`crates/buzz-acp/src/config.rs`)

Add `hide_env_values = true` to each. Env var names remain visible for
discoverability; only their runtime values are withheld from `--help`
output.

Also adds a regression guard in each crate's test module that walks the
clap command tree (recursing into subcommands for `buzz-cli`) and
asserts every arg whose env var name contains `KEY`, `SECRET`, `TOKEN`,
`PASSWORD`, `CRED`, or `AUTH` has `hide_env_values` set. This prevents
future credential-bearing args from being added without the masking in
place.

6438dedf83 feat(agent): route Claude/GPT model families to their native gateway wire (#3538)
## Summary

Databricks v2 chooses the gateway wire format — OpenAI Responses,
Anthropic Messages, or MLflow chat — purely from substrings in the
endpoint name. There is no family field on the endpoint to key off, so
the substring set *is* the routing contract. The matcher only recognised
`gpt-5`/`gpt5` and `claude`, which makes correct billing depend on every
Claude endpoint happening to be named with the literal string "claude".

## Why this matters

Getting a Claude model onto the Anthropic Messages route is exactly what
lets buzz attach the `cache_control` breakpoint (the fix in #3463). If a
Claude endpoint's catalog name omits "claude" — an alias, a bare
`opus-5`, a `goose-opus-5` — it silently falls through to the MLflow
(OpenAI-wire) path, where Anthropic prompt caching is **structurally
impossible**. The result is the same failure #3463 fixed: 0% cache
reads, the full ~10x read discount lost, and no error — a naming
convention quietly holding up a billing-correctness invariant.

## What changed

`databricks_v2_route_for_model` (`crates/buzz-agent/src/llm.rs`) now
matches broader, case-insensitive marker sets:

- **Claude → Anthropic Messages:** `claude`, `opus`, `sonnet`, `haiku`,
`mythos`, `fable` — the Claude family names and release code names, so a
Claude endpoint reaches the cache-capable route regardless of how it's
named.
- **GPT → OpenAI Responses:** the `gpt` family (now `gpt` on its own,
not just `gpt-5`) plus the GPT-5 launch code names `sol`, `luna`,
`terra`.

OpenAI markers are evaluated first, preserving the prior `gpt-5`-first
precedence for any name that could carry both. Names matching neither
set still fall through to the MLflow chat route.

## Testing

- `cargo fmt`, `cargo clippy -p buzz-agent --all-targets -- -D warnings`
— clean.
- `cargo test -p buzz-agent` — all green (299 lib + integration suites,
0 failures). The `databricks_v2_routes_by_model_family` test was
expanded to cover each new marker, the GPT-5 code names,
case-insensitivity, and the unchanged MLflow fallback (including
`gemini`).

## Relationship to #3463

#3463 taught the Anthropic path to request caching; this makes sure
Claude models actually land on that path. Follow-up still open:
surfacing `cache_creation_input_tokens` end-to-end so a persistent
`reads == 0 && writes == 0` reveals a disabled cache regardless of which
wire a model takes — happy to do that next.

c405ad1d4b feat(agent): fix Anthropic prompt caching with Databricks (+ MCP proxy/TLS passthrough) (#3463)
> On 8 tasks matched by name across the two runs, cost fell $8.36 →
$1.77 (4.71×) and wall-clock 12,423 s → 1,085 s (11.45×).

## Summary

Two independent, self-contained fixes to `buzz-agent`/`buzz-acp`, split
out of the benchmark branch so they can land while the harness work
continues:

1. **Request and surface Anthropic prompt caching.** buzz never sent a
`cache_control` breakpoint, so on the Databricks Anthropic route
`cache_read_input_tokens` was **structurally always 0** and the ~10×
cache-read discount was never claimed. This teaches `anthropic_body()`
to mark the cacheable prefix, and plumbs the cache split end-to-end so
accounting can price it.
2. **Pass proxy + TLS-trust env into MCP tool subprocesses**, so agent
tools on a proxy-only host stop reporting a live network as offline.

## Why the caching gap matters

The Anthropic Messages API does **not** cache unless the request carries
a `cache_control` breakpoint, and the Databricks AI Gateway — a
third-party proxy in front of the model, in the same category as
Bedrock/Vertex — does **not** auto-cache (only the first-party Anthropic
API and Claude-on-AWS do zero-config caching). So every request was
billed cold.

Measured live against the Databricks gateway
(`databricks-claude-opus-5`, 2026-07-28), the same call with and without
a single `cache_control` marker:

| Run | `input_tokens` | `cache_creation` | `cache_read` | latency |
|---|---|---|---|---|
| No `cache_control`, two byte-identical calls | 121,625 | 0 | **0** |
~9.3 s |
| With one marker — cold (write) | 4 | 121,625 | 0 | 9.3 s |
| With one marker — warm (read) | 4 | 0 | **121,625** | **4.5 s** |

One marker moved 121,625 tokens from full-price input to a 0.1× cache
read and roughly halved latency (a clean, isolated ~2.07× prefill
speedup on this single-threaded microbenchmark). The gateway honours
`cache_control`; buzz simply never sent it.

At fleet scale this was a real budget item. Across matched
Terminal-Bench solo sweeps (89 tasks, `-n 20`, before the fix), the two
OpenAI-route models independently landed at ~86–87% cache reads — the
expected shape for an agentic loop, where system + tools + append-only
history repeat every turn — while the Anthropic route returned a hard 0%
on every receipt:

| Condition | Route | Input tokens | Cache reads | Cost | Cost if
uncached | Discount |
|---|---|---|---|---|---|---|
| luna (`gpt-5-6`) | OpenAI | 20,320,818 | **17.7M (87.0%)** | $6.96 |
$22.87 | **3.28×** |
| sol (`gpt-5-6`) | OpenAI | 22,312,290 | **19.2M (85.9%)** | $37.07 |
$123.35 | **3.33×** |
| opus (`claude-opus-5`) | Anthropic | 12,459,822 | **0 (0.0%)** |
$81.31 | $81.31 | **1.00×** |

Applying luna's measured 87% read rate to the opus token counts at list
prices (`input $5/M`, `cached_input $0.5/M`, `output $25/M`) puts the
opus run at **~$32.53 vs the $81.31 actually paid — a ~60% overspend on
those 49 trials (~$89 on a full sweep)**. That is an upper bound (it
prices every cached token at the 0.1× read rate and ignores the 1.25×
write premium), and the opus discount is structurally smaller than
luna/sol's because opus emits ~3.5× more uncacheable output per trial,
which sets a floor on what caching can recover.

There is also a plausible **second-order effect**: Databricks appears to
meter its per-minute rate limit on *uncached* input tokens, so the
missing cache also cost rate-limit headroom — the opus endpoint lost 63%
of its trials to fatal 429s while running alone at one-third of a GPT
endpoint's raw throughput. This is a hypothesis, not a proven mechanism
(the only zero-cache condition is also the only Anthropic endpoint), but
it is the reading that explains the throttling with one rule instead of
two.

## Post-fix results (provisional — first trials of an in-flight re-run)

On 8 tasks matched by name across the two runs, cost fell **$8.36 →
$1.77 (4.71×)** and wall-clock **12,423 s → 1,085 s (11.45×)**.

| Metric | before (`4a955a858`) | after (`3bef1f6a`) |
|---|---|---|
| Cache reads as % of input | **0.0%** | **78.7%** (still climbing
toward the ~86% steady state) |
| `cost_usd_no_cache_discount / cost_usd` | **1.00×** | **2.18×**
(tracking the projected ~2.5×) |
| Trials with a fatal 429 (same `-n 20`) | **63%** | **15–19%** |

To be clear about attribution: **~2× of that is the clean prefill saving
from caching itself**; the rest is second-order — cached requests burn
far less rate-limit budget, so they stall less and redo less destroyed
work. The 11.45× is a system-level result specific to this throttled
workspace, not a caching benchmark. Quality held (7/8 solved in each
run). A controlled low-`-n` A/B (neither arm hitting a 429), which the
`BUZZ_AGENT_PROMPT_CACHING` opt-out exists to enable, is still owed
before this becomes a published claim.

## What changed

### 1. Request caching (`llm.rs`, `config.rs`)

`anthropic_body()` emits ephemeral `cache_control` breakpoints, gated by
`BUZZ_AGENT_PROMPT_CACHING` (**default on**, `=0` to opt out):

- **Static prefix** — marker on the `system` block. Prefix order is
`tools → system → messages`, so this single marker caches **tools +
system** together. Byte-identical on every turn of a run, and survives a
context handoff (system/tools come from cfg/mcp, not `self.history`).
- **Rolling tail + leapfrog** — marker on the last block of the last
**two** messages. The append-only history re-reads the prior turn's
prefix from cache; marking two messages (not one) keeps consecutive
breakpoints inside Anthropic's **20-block lookback window** even as tool
parallelism rises, avoiding a silent full-price miss.

An empty system prompt stays a bare string (Anthropic rejects empty text
blocks), and below-threshold prefixes are silently not cached, so the
flag is safe on by default.

### 2. Surface the cache split end-to-end — the plumbing (`types.rs`,
`llm.rs`, `agent.rs`, `lib.rs`, `usage.rs`, `acp.rs`)

This is the part that makes gaps like the one above **visible** instead
of silent. A consumer that prices all of `input_tokens` at the full rate
can't tell a route that's caching from one that isn't — the total looks
right either way. So:

- `LlmResponse` gains `cached_input_tokens` (a **subset** of
`input_tokens`, never an addition); `parse_anthropic` / `parse_openai` /
`parse_responses` each populate it.
- A `usage_first()` helper reads the cache count wherever a provider
hides it — flat `cache_read_input_tokens` (Anthropic),
`prompt_tokens_details.cached_tokens` (OpenAI chat),
`input_tokens_details.cached_tokens` (Responses) — taking the **first
present value, never a sum**. Reading only flat keys is exactly why the
OpenAI route's nested `cached_tokens` had *also* been going unclaimed:
`prompt_tokens` is already inclusive, so the total looked correct while
the discount silently went unreported.
- The per-turn/per-session accumulators and the goose `usage_update`
payload now carry `accumulatedCachedInputTokens`; `buzz-acp`
deserializes it (`serde` default `0` for goose, which doesn't send it)
and logs `cached=<n>`.

### 3. Fix a Databricks MLflow-route double-count (`llm.rs`)

The Databricks MLflow route reports the flat Anthropic-spelled
`cache_read_input_tokens` *alongside* an already-inclusive
`prompt_tokens`, so the old code summed them and nearly doubled the
count — inflating both the context-budget gate and cost.
`openai_chat_input_tokens()` now reads `prompt_tokens` alone. Verified
on a live `databricks-glm-5-2` response where `prompt_tokens +
completion == total` proves inclusivity. (Anthropic's native route
genuinely *excludes* the cache fields and is still summed — the two
never collide, because `claude*` models route to the Anthropic path.)

### 4. Proxy + TLS-trust passthrough into MCP tools (`mcp.rs`) —
independent fix

`buzz-agent` `env_clear()`s each MCP child, and the allowlist carried no
proxy/TLS vars. On a proxy-only host that doesn't degrade the tools, it
**blinds** them: apt, curl, pip, git connect directly, the egress
firewall resets the socket, and the agent reports "Connection reset by
peer" — indistinguishable from a genuinely offline task. Adds both
spellings of `HTTP(S)_PROXY`/`NO_PROXY`/`ALL_PROXY` (curl/git read
lowercase; Go/Python read uppercase; libcurl ignores uppercase
`HTTP_PROXY`) plus `SSL_CERT_FILE`/`SSL_CERT_DIR` for TLS-terminating
proxies that present their own CA.

## Testing

- `cargo fmt --all -- --check`, `cargo clippy -p buzz-agent -p buzz-acp
--all-targets -- -D warnings` — clean.
- `cargo test -p buzz-agent -p buzz-acp` — **all green** (632 + 299 lib
tests plus integration suites, 0 failures). New tests cover: the three
breakpoints and the disabled/empty-system/single-message edge cases;
nested-vs-flat cache parsing for all three routes; the Databricks
inclusive-`prompt_tokens` fix; wire deserialization of
`accumulatedCachedInputTokens`; and the proxy/TLS passthrough allowlist.
- Pre-push lefthook suite green (branch-skew, rust-tests, test,
desktop-check/test/tauri).

## Relationship to the benchmark branch

These are the non-`benchmarks/` changes from
`benchmark/harness-accounting-and-solo`, lifted onto a clean base off
`main` so they can merge independently.

6300a6b1d0 fix(acp): per-runtime env defaults at spawn — isolate Hermes from configured MCP startup (#3420)
## Summary

- add a generic per-runtime env-defaults table,
`config::default_agent_env()`, mirroring the existing
`default_agent_args()` / `codex_network_env()` precedent, and merge it
once in `AcpClient::spawn` with the established precedence: **runtime
defaults < persona `extra_env` < inherited parent env**
- first (and only) row: Buzz-owned Hermes processes get
`HERMES_ACP_SKIP_CONFIGURED_MCP=1`, so Hermes does not preload unrelated
profile-configured MCP servers before answering ACP `initialize` (fixes
the 10s model-discovery timeout in #3355 — Buzz supplies session MCP
servers explicitly through `session/new`, per Hermes's documented
host-integration contract for this variable)
- normalize Windows `.cmd`/`.bat` shims alongside `.exe` in
`normalize_agent_command_identity` (npm installs resolve to those
wrappers)
- switch the `extra_env` parent-presence check from `var()` to
`var_os()` so non-UTF-8 parent values are honored

Replaces the runtime-specific approach in #3386: same behavior, but the
mechanism is generic runtime spawn metadata in `config.rs` rather than a
Hermes/ACP special case in `acp.rs`, and the seam covers every launch
path (Desktop spawn, `buzz-acp models`, CLI) because they all funnel
through `AcpClient::spawn`. ~15 lines of production code.

Fixes #3355

## Testing

- `cargo test -p buzz-acp` — **639 passed, 0 failed** (full package,
includes the new `default_agent_env_recognizes_hermes_identities` unit
test and `spawn_applies_runtime_env_defaults_with_extra_env_precedence`
integration test covering default injection, extra_env override, and
non-Hermes exclusion)
- `cargo fmt --all -- --check`, `cargo clippy -p buzz-acp --all-targets
-- -D warnings` — clean
- live-local with real Hermes v0.19.0 (`hermes-acp`): `buzz-acp models`
returned **13 models / currentModelId in 2.6–3.0s** (was a 10.0s timeout
on the first cold run without isolation); a wrapper probe confirmed the
child received `HERMES_ACP_SKIP_CONFIGURED_MCP=1` by default and `0`
when the parent env set it explicitly (operator wins)
- lefthook pre-push suite green: rust-tests, desktop-check,
desktop-test, desktop-tauri-test, mobile-test, branch-skew

No UI changes; subprocess environment behavior only.

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.

f25e6dd6aa feat(acp): steer claude-code and codex agents via _session/steering (#3007)
Mid-turn steering was reachable only through goose's
`_goose/unstable/session/steer`, which requires an `expectedRunId`
sourced from `_meta.goose.activeRunId`. claude-agent-acp and codex-acp
never emit a run id, so every mid-turn mention to those harnesses bailed
at the run-id guard before writing a byte and degraded to cancel +
merge, destroying in-flight tool calls.

Both adapters ship `_session/steering` (params `{sessionId, prompt}`,
result `{outcome}`) and advertise it as `_meta.steering.supported` on
the `initialize` response. This adds it as a second steer transport
selected at write time, reusing the existing withhold/release, ack
routing, and cancel+merge fallback machinery unchanged.

## Transport selection

| `active_run_id` | `steering_supported` | Transport |
|---|---|---|
| `Some(run_id)` | any | `_goose/unstable/session/steer` +
`expectedRunId` (unchanged) |
| `None` | `true` | `_session/steering` with `{sessionId, prompt}` |
| `None` | `false` | ack `ExpectedRunIdMissing`, write nothing
(unchanged) |

goose keeps priority when both are present — `expectedRunId` is strictly
more precise about *which* run is being steered.

## Two load-bearing safety properties

**The advertised capability is the only gate — never error-code
probing.** codex-acp's `extMethod` answers unrecognized extension
methods with a bare `{}`, which is a JSON-RPC *success* rather than
`-32601`. Buzz maps a steer success to `queue.remove_event`, so probing
an unknown method would silently delete the user's message with no
error, no fallback, and no log line.

**An `outcome` must be positively recognized.** Only `injected` and
`startedNewTurn` count as delivery. Anything else — codex's `failed`, an
unknown value, or a missing `outcome` entirely — is
`SteerError::OutcomeRejected`, which releases the withheld event and
fires the cancel+merge fallback. This makes the silent-loss path above
unreachable even if an adapter mis-advertises.

`startedNewTurn` acks `Success`, because the message really was
delivered and must not be redelivered, but deliberately does **not**
renew the read loop's hard deadline: the turn Buzz was awaiting had
already settled, and renewing would extend the clock on a finished turn.

## Notes for reviewers

- `SteerError::OutcomeRejected` needs no new arm in the
`PoolEvent::SteerAck` match — the existing catch-all
`Ok(SteerAck::Err(_)) => (true, false, true)` already gives release +
fallback, and the two `AgentError` arms above it match that variant
specifically, so they do not shadow it.
- Comments that described the old goose-only "try-and-tolerate" `-32601`
behavior are corrected; that assumption was never valid for codex-acp.
- No CI job runs `buzz-acp` tests. The full package suite was run
locally: **617 passing, 0 failing**.

Will PflegerandGitHub 1d4f97b959 fix(acp): disable goose cron scheduler in managed agent children (#3144)
A Buzz install with a scheduled goose recipe fires each cron entry once
per `goose acp` child instead of once, because every child
unconditionally starts its own cron scheduler over the shared
`~/.local/share/goose/schedule.json`. With a pool of N children per
harness and multiple harnesses, one scheduled recipe fans out to N ×
harness_count executions — each running under the managed agent's
identity rather than the operator's, and racing the operator's own
standalone goose over the same schedule file.

This injects `GOOSE_ACP_SCHEDULER_DISABLED=true` into every child
spawned by `AcpClient::spawn`, so a managed agent never owns the
operator's cron schedule.

## Placement

The `cmd.env` call is set last — after the `extra_env` operator-wins
loop and after the `CODEX_CONFIG` merge — deliberately with no escape
hatch. Managed children not running the operator's schedule is a
correctness invariant rather than an operator-tunable default, so the
injection must beat both a conflicting persona `extra_env` entry and any
value inherited from the parent process.

It is injected for all agents, not just goose. Agent builds that don't
recognize the variable ignore it.

## Sequencing

The goose-side flag that reads this variable and skips scheduler startup
lands separately (repo TBD). Until it does, this change is a
forward-compatible no-op: it sets an environment variable nothing
currently reads. Merging it first means no coordinated release is needed
— the fix takes effect as soon as the goose side ships.

60158fce3e feat(cli): add users set-status command for NIP-38 profile status (#3253)
## Summary

The desktop client renders a persistent user status (NIP-38 kind:30315,
`d:general`) as the status line on profiles, but the CLI had no way to
set it — only ephemeral presence (`set-presence`, kind:20001).
Integrations that want a scriptable, durable status line (for example a
now-playing music bridge that shows the current TIDAL track on a
profile) had no entry point.

This adds:

```bash
buzz users set-status --text "Working on the relay" --emoji "🔧"
buzz users set-status --text "" --emoji "🎶"   # intentional emoji-only status
buzz users set-status --clear                  # removes the status
```

- Signs and submits the replaceable kind:30315 event via the HTTP bridge
(no WS needed — unlike presence, user status is a stored event).
- Uses the `d:general` coordinate the desktop client already reads for
the profile status line, and the same `emoji` tag shape
`SetStatusDialog` publishes.
- Event construction lives in `buzz_sdk::build_user_status()`, keyed off
`buzz_core::kind::KIND_USER_STATUS`, so the CLI command is a thin
sign/submit wrapper. Text and emoji are trimmed; a blank emoji is
omitted rather than emitted as an empty tag.
- Clearing is the explicit `--clear` flag, mutually exclusive with
`--text`/`--emoji`. It publishes an empty-content event carrying only
`d:general`, which the desktop treats as no status. `--text ""` with an
`--emoji` is an emoji-only status, not a clear.

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.

925a9a7bf2 fix(buzz-acp): accept id-keyed config options when resolving model switch (#2795)
## Summary

Fixes #2794. Related: #2692.

`resolve_model_switch_method()` reads the `configId` key from each
`session/new` `configOptions` entry and skips entries that lack it.
`claude-agent-acp` (v0.61.0) keys its entries with `id`, so every
model-category entry was skipped, the desired model never matched, and
Claude Code sessions fell back to the CLI default from the user's
`~/.claude/settings.json`. The only trace was a `pool::model` WARN that
never reaches the per-agent log files.

This is the ACP-side half of the symptom reported in #2692. The open
desktop-side PRs (#2695, #2701, #2696) inject `ANTHROPIC_MODEL` at
spawn, which masks the problem for spawn-time selection but leaves the
config-option switch path broken.

## Changes

- `resolve_model_switch_method()` accepts either `configId` or `id` when
extracting the config id. The set request is unchanged: the ACP SDK
schema takes `configId` as the request param and the adapter resolves it
against its `id`-keyed entries, so only the read side needed fixing.
- Regression test with an `id`-keyed `configOptions` payload mirroring
the real adapter response (including `models: null`, so the unstable
fallback path cannot rescue the match).
- Doc comment on `extract_model_config_options()` notes the key drift.

## Testing

`cargo test -p buzz-acp --lib`: 599 passed, 0 failed. The new test fails
on main and passes with this change.

Verified against the real adapter: a stdio JSON-RPC probe of the bundled
`claude-agent-acp` 0.61.0 confirms `session/new` returns `id`-keyed
config options with `opus[1m]` present as a value, and the SDK's
`SetSessionConfigOptionRequest` schema accepts `{sessionId, configId,
value}` as sent by `session_set_config_option()`.

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.

9b0f744804 resolve findings (#3150)
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.

2026-07-27 14:10:16 -04:00
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`)

Will PflegerandGitHub f2fe3b63c2 feat(acp): title agent sessions from the agent and channel name (#3028)
ACP harnesses that name a session from the first text they receive all
land in the same place: every managed Buzz agent opens with the
identical `[Base] You are operating inside the Buzz platform…` framing,
so the harness session list shows a wall of indistinguishable rows.
Because sessions are keyed per channel, one agent active in several
channels produces several of them.

This sends the name out of band instead. `session/new` carries
`_meta.sessionTitle` with `Agent · #channel`, composed from the agent's
`display_name` (or its unique `name` handle) and the channel it is
serving. The prompt is untouched — no tokens spent, no perturbation of
the prompt contract, and nothing new for the desktop observer's section
parsing to handle.

The mechanism is harness-agnostic: Buzz sends the field on every ACP
`session/new` regardless of which harness is behind it, and adapters
that don't read it ignore it per spec.

## Inert until a consuming adapter ships

ACP adapters ignore `_meta` members they do not recognize, so against an
adapter with no reader a Buzz session gets no title and nothing else
changes. Three adapter halves consume it — Codex, Goose, and Claude Code
(linked below); this half and each reader are only useful together, and
each reader lands independently.

No version floor is added. `codex_adapter_is_outdated_with_path` already
gates codex-acp on major version `>= 1`
(`desktop/src-tauri/src/managed_agents/discovery.rs:1276-1284`) and this
feature needs nothing above that — an older adapter is not broken by the
extra member, it simply ignores it.

## What changes

**`crates/buzz-acp`** owns sanitization and composition.
`sanitize_session_title` collapses whitespace, drops control characters,
and caps at `SESSION_TITLE_MAX_CHARS` (80) by character, not byte, so a
multi-byte character cannot be split. `compose_session_title` truncates
only the channel part against that cap, so the agent name always
survives; when the agent name alone fills the cap the channel is dropped
rather than the name. `session_new_full` sets `_meta.sessionTitle` when
a title exists and omits `_meta` entirely when it does not, since an
adapter may distinguish an absent member from a null one.

**`desktop/src-tauri`** only resolves and exports.
`resolve_session_title` picks `display_name` or falls back to `name`,
and `spawn_agent_child` writes it to `BUZZ_ACP_SESSION_TITLE` — or
removes the variable when neither candidate yields anything printable.

DMs, unresolved channels, and heartbeat sessions get the bare agent name
with no channel suffix.

## Four properties that are easy to remove by accident

**Control characters are stripped at the desktop boundary, not in the
harness.** An interior NUL cannot cross the environment boundary at all
— `Command::env` fails the entire spawn rather than passing it through.
Deferring the strip to `buzz-acp` would let a corrupted display name
turn display chrome into a spawn failure. A display name that is *only*
control characters falls back to `name`.

**The title is hashed into `spawn_config_hash`.** Without it, renaming
an agent left the running process with a stale title and no restart
badge. The hash runs the same `resolve_session_title` the spawn writes,
and skips it when a user env override shadows `BUZZ_ACP_SESSION_TITLE` —
spawn writes the title *before* the layered user env, so the override is
what actually runs, and it already reaches the hash through
`descriptor.env`. Hashing the record-derived value under an override
would badge a rename that changes nothing.

**One channel resolve serves both consumers.**
`resolve_new_session_channel_context` returns `(is_dm, title_channel)`
from a single metadata lookup, feeding both the canvas block's DM check
and the title. `ChannelInfoResolver` caches only `Some`, so two
independent calls against an unresolvable channel pay the full
`fetch_channel_info` retry sequence twice — two timeouts plus a retry
delay each — directly in front of `session/new`, precisely when the
relay is already degraded.

**The `"unknown"` channel name is treated as absent.**
`fetch_channel_info` substitutes the literal `"unknown"` for a metadata
event with no `name` tag. Composing that sentinel would title every
unnamed channel `Agent · #unknown`, reintroducing the exact collision
the suffix exists to remove while naming a channel something it isn't.
The startup cache already refuses `channel_type == "unknown"` for the
same reason.

Closes #2334

18eef633d8 feat(git): use agent display name as git author name (#3040)
Agent commits were authored by a raw 63-character npub, which makes `git
log`, `git blame`, and GitHub's author column effectively unreadable.
This uses the agent's display name for `user.name` instead, while
leaving the pubkey where it does real work.

## What changes

`build_git_env` in `crates/buzz-dev-mcp/src/shim.rs` now reads
`BUZZ_ACP_DISPLAY_NAME`, sanitizes it, and uses the result as
`user.name`. When the variable is absent or unusable it falls back to
`info.npub` — byte-identical to today's behavior.

`user.email`, `user.signingkey`, and the whole credential/signing block
are untouched. The pubkey is what NIP-98 auth, NIP-GS signing, and
contributor matching key on, and it stays in the email verbatim.

`crates/buzz-acp/src/lib.rs` forwards the variable into the dev-mcp
server's declared env, mirroring the existing `BUZZ_AUTH_TAG` block. It
reads `std::env::var` directly rather than going through `Config`, so
the variable is picked up whenever the process has it.
`crates/buzz-agent/src/mcp.rs` adds one `PASSTHROUGH_ENV` entry so ACP
clients that spawn `buzz-agent` without declaring the variable on the
wire still propagate it.

## Why a dedicated variable

`BUZZ_ACP_DISPLAY_NAME` is its own contract rather than a reuse of the
ACP session title. Commits outlive sessions: a session title is
per-session UI chrome and may be composed downstream into `Agent ·
#channel`, and if that composed form ever reached the env var, git
attribution would change silently with no test able to catch it. Git
identity gets a variable whose contract is "bare agent display name,
never channel-qualified."

Nothing writes it yet — a one-line Desktop write lands as a follow-up.
Until then `std::env::var` returns `Err`, the npub fallback fires, and
behavior is byte-for-byte current `main`.

## Sanitizing

Strip control characters, Unicode format characters, and angle brackets;
collapse whitespace runs, trim, cap at 80 characters (by `chars()`, so a
multi-byte name is never split mid-UTF-8).

Angle brackets go because git drops them silently rather than erroring:
`Duncan <evil@x.com>` renders as `Duncan evil@x.com <hex@relay>`. It
forges nothing, but it reads as though it might.

The empty result also has to cover more than literal emptiness. git's
`ident.c` treats a set of characters as "crud" — stripped from both
ends, and fatal when a name is *nothing but* those characters:

```
$ git -c user.name=';;' commit -m t
fatal: name consists only of disallowed characters: ;;
```

Verified against git 2.54.0 by committing with each ASCII byte 32..=126
as the entire `user.name`: exactly space, `"`, `'`, `,`, `:`, `;`, `<`,
`>`, `\` abort, plus all control characters (the predicate is `c <=
32`). `.` is not crud in this version, despite older lore. Names that
merely *contain* crud are fine — `O'Brien` and `Smith, Jr.` both commit
cleanly — so the check is "at least one non-crud character survives,"
not "no crud present." Without it, a display name of `;;` or `""` would
abort every commit that agent makes.

## Unicode format characters

`char::is_control` covers only category `Cc`. Category `Cf` — zero-width
spaces and joiners, bidi embedding and override marks, invisible math
operators, tag characters — is neither control, nor whitespace, nor git
crud, so those characters survived every one of the checks above. A
display name of nothing but U+200B ZERO WIDTH SPACE therefore satisfied
"at least one non-crud character survives" and git accepted the commit
with a visually blank author:

```
# pre-fix, BUZZ_ACP_DISPLAY_NAME set to two U+200B
$ git log -1 --format='%an' | xxd -p
e2808be2808b0a
```

Embedded marks were the other half: a trailing U+202E RIGHT-TO-LEFT
OVERRIDE reorders everything after it, so a stored author line renders
as something other than what it stores — the same confusion class the
angle-bracket filtering exists to prevent.

`is_unicode_format` rejects the whole `Cf` category rather than the
known-bad marks, because the boundary that matters is "invisible or
reorders text", not "the codepoint someone thought of". The 21 ranges
come from the UCD's `DerivedGeneralCategory.txt` (17.0.0), cross-checked
against Python's `unicodedata` (16.0.0); both yield exactly the same
set. They are inlined as a `matches!` rather than pulling in a
Unicode-tables crate for one predicate, and a test asserts both
endpoints of every range plus the codepoints immediately outside them —
including U+2065, which sits inside the U+2060 block but is unassigned
rather than `Cf`.

Filtering happens inside the existing per-word filter, so a format-only
name collapses to empty and falls out through the same `None` → npub
path as a crud-only name. No new fallback logic. And because filtering
precedes truncation, invisible padding cannot eat the 80-character
budget.

## NUL is handled one layer up

An interior NUL is a sibling constraint that cannot be fixed here: it
makes `Command::env` fail the entire spawn before this code runs, so it
has to die at the writer. #3028 establishes that pattern for the session
title in `resolve_session_title` via `filter(|c| !c.is_control())`, and
the Desktop follow-up that writes `BUZZ_ACP_DISPLAY_NAME` inherits it.
The shim sanitizer is a second line of defense for values that arrive
from somewhere other than Desktop.

## Verified end to end

Driving the real `buzz-dev-mcp` binary over stdio MCP and committing
inside its shimmed environment:

```
# BUZZ_ACP_DISPLAY_NAME="Duncan Idaho"
Duncan Idaho <dcfd242e...0f95@buzz.block.builderlab.xyz>
verify_exit=0

# BUZZ_ACP_DISPLAY_NAME unset
npub1mn7jgtj4w2pd0g0zeuhxsa6jy6p0rewxz4kujt98my82ahfmp72sxjexk7 <dcfd242e...0f95@buzz.block.builderlab.xyz>
verify_exit=0

# BUZZ_ACP_DISPLAY_NAME=";;"  (crud-only; would otherwise be fatal)
npub1mn7jgtj4w2pd0g0zeuhxsa6jy6p0rewxz4kujt98my82ahfmp72sxjexk7 <dcfd242e...0f95@buzz.block.builderlab.xyz>
verify_exit=0

# BUZZ_ACP_DISPLAY_NAME=U+200B U+200B  (format-only; would otherwise be blank)
npub1mn7jgtj4w2pd0g0zeuhxsa6jy6p0rewxz4kujt98my82ahfmp72sxjexk7 <dcfd242e...0f95@buzz.block.builderlab.xyz>
verify_exit=0

# BUZZ_ACP_DISPLAY_NAME="Duncan" + U+202E  (bidi override stripped)
Duncan <dcfd242e...0f95@buzz.block.builderlab.xyz>
verify_exit=0

# BUZZ_ACP_DISPLAY_NAME="Dun" + U+200B + "can"  (zero-width removed, word not split)
Duncan <dcfd242e...0f95@buzz.block.builderlab.xyz>
verify_exit=0
```

Signature verification passes in every case — the signing identity is
unchanged.

`Related: #3028` — it establishes the Desktop-side env plumbing this
builds beside; the one-line Desktop follow-up that writes
`BUZZ_ACP_DISPLAY_NAME` alongside the session title ships after it
merges. Not a dependency: with the variable absent, `std::env::var`
returns `Err` and the npub fallback keeps current behavior exactly.

e2e0079101 fix(security): enforce durable community ban on NIP-43 relay-admin kinds 9030-9033 (#3128)
## Summary

`ingest_event`'s durable write-path restriction gate exempts NIP-43
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.

thomaspblockandGitHub c5c4f390b6 feat(desktop): handle project work from Inbox (#3117)
## Summary

Pull requests and issues that mention you now appear as
repository-scoped Inbox conversations, so project work can be reviewed
without first navigating to Projects.

Opening a project item resolves its current canonical state and reuses
the existing review, comment, merge, and issue actions. Repository-aware
grouping keeps identical event IDs from different repositories separate,
while loading, missing-data, and partial-query states avoid exposing
stale actions.

### Related issue

None found.

### Testing

- `node --import ./test-loader.mjs --experimental-strip-types --test
src/features/home/lib/projectInbox.test.mjs` — 6 tests passed
- `CI=1 pnpm exec playwright test tests/e2e/project-inbox.spec.ts
--project=smoke` — passed
- Pre-push desktop, mobile, Tauri, and Rust checks — passed

95fdf97880 feat(acp): bring your own harness (BYOH) — generic ACP runtime seam + settings gallery (#2773)
## What

Implements a "bring your own harness" (BYOH) generic ACP mechanism —
replacing per-harness backend code with a data-driven 3-tier system:

- **Tier 1 (compiled-in builtins):** goose, claude, codex, buzz-agent —
unchanged behavior
- **Tier 2 (bundled presets):** cursor, omp, grok, opencode, kimi, amp,
hermes, openclaw, and any future additions — defined in
`PRESET_HARNESSES`, no code duplication, icons stay
TerminalSquare/bundled-asset-only
- **Tier 3 (user-defined custom):** JSON definitions saved to
`custom_harnesses/` under app data; managed via Settings → Agents UI

## Changes

### Core data model
- `HarnessDefinition` — id, label, command, args, env, install URL/hint
- `PRESET_HARNESSES` static table — single source of truth for all
presets; `preset_harness_ids()` derives reserved IDs (D-11: no
hand-maintained copy)
- `source: "builtin" | "preset" | "custom"` tagging on every catalog
entry

### Persistence (B-4, B-6)
- `save_custom_harness_to_dir(dir, definition, rename_old_id)` —
backup-swap atomic write (backs up target → .bak, commits temp → target,
restores .bak on failure, removes .bak on success); safe on Windows
where `fs::rename` over an existing file is "access denied"
- `save_and_warm` / `delete_and_warm` — hold `PERSIST_MUTEX` for the
write + registry-warm pair, eliminating the lost-update race (B-6) where
two concurrent saves could interleave their warm calls and leave a stale
registry snapshot
- Validate-before-mutate: both IDs and env validated before any
filesystem mutation

### Env validation boundary (B-3)
- `validate_harness_definition_pub` calls `validate_user_env_keys` on
definition env at save AND load
- Rejects malformed keys (BUZZ_AUTH_TAG=x forgery shape), reserved keys
(BUZZ_MANAGED_AGENT etc.), NUL bytes, oversized values

### TypeScript boundary (B-2 / Thufir CRITICAL)
- `RawAcpRuntimeCatalogEntry` now declares `definition_env?:
Record<string,string>` and `source: "builtin" | "preset" | "custom"`
- `fromRawAcpRuntimeCatalogEntry` maps `definition_env → definitionEnv`
(camelCase); absent field defaults to `{}`
- Edit form reads `entry.definitionEnv` — env no longer erased on
save-then-edit cycle

### Unified descriptor (Phase A / Thufir F4)
- `EffectiveHarnessDescriptor { command, args, env }` in `readiness.rs`
- `resolve_effective_harness_descriptor()` — single resolver used by
spawn, spawn_hash, summary, get_agent_models (both saved and unsaved),
and readiness
- No competing arg-resolution forms

### Other fixes
- B-5: stop freezing `runtime.defaultArgs` into `record.agent_args` on
normal create paths
- B-7: readiness exec-check — `MissingBinary` variant for custom
commands not found on PATH
- B-8: onboarding transition — `setTimeout(0)` removed, parent-owned
route intent via `navigateAfterComplete` prop
- C-9: collector-discriminating sweep tests with injectable filters
- C-10: `HarnessManagementCard` uses `harnessGalleryLogic` helpers
(killed duplicate filter/sort)
- D-11: `BUILTIN_IDS` derived from `PRESET_HARNESSES` (no
hand-maintained copy)
- D-12: `mobile/pubspec.lock` churn reverted
- D-13: false ownership fast-path comment fixed
- D-14: URL scheme validation for `installInstructionsUrl`
- D-15: OpenClaw Gateway env-locus README line

### Tests added
**B-4 persistence (6 tests):**
`save_to_dir_create_writes_file_and_loads_back`,

`validate_rejects_value_over_per_value_size_limit`,
`validate_accepts_well_formed_env`

**B-2 API boundary (4 TS tests in tauri.test.mjs):**
`fromRawAcpRuntimeCatalogEntry maps definition_env to definitionEnv`,
`defaults definitionEnv to {} when absent`, `preserves source preset`,
`env round-trips through edit payload shape`

## Review-fix pass (2026-07-26, Eva)

Fixes from the three-way review (Wren / Dawn / Eva) in the
buzz-generic-acp-harnesses thread, pushed as new commits (no rewrite):

1. **installHint edit round-trip** — form seeding extracted to
`formValuesFromCatalogEntry` (single source of truth), input rendered,
full-definition lossless round-trip regression.
2. **Dangling-delete coherence** — delete allowed; confirm counts
referencing agents (direct pin + persona-inherited); summary rows render
`harness (deleted): <id>`; spawn errors become actionable sentences
(`user_facing_harness_error`); composed delete→summary→start test.
3. **Comma-in-args** — rejected at `validate_harness_definition` (shared
by save AND disk load), mirrored inline in the form.
4. **Registry publish race** — collision/dup filtering moved into
`load_custom_harnesses` (both loaders inherit shadowing rules);
discovery publishes by re-reading the dir under `persist_mutex` (lock
scoped to publish only); deterministic interleaving regressions for
save-during-discovery and delete-during-discovery.
5. **Mechanical** — discarded `belongs_to_us` sweep arg deleted,
`load_global_agent_config` hoisted out of the per-record summary loop,
duplicated doc paragraph + stray SAFETY comment removed.
6. **PGID test de-flaked** — leader kept alive through the assertion.

Known follow-up (filed in review, not blocking): file-size split-outs
queued in `check-file-sizes.mjs` entries.

16d4ec335e feat(desktop): use collective mesh routing for Auto (#2825)
Uses MeshLLM built-in `mesh` collective intelligence / Mixture of Agents
when Buzz Auto sees two or more distinct physical models. With zero or
one model, Auto remains ordinary `auto`. This is an alternative way to
improve tool responses, accuracy, and resistance to hallucination when a
high-latency distributed mesh contains diverse models.

Models and members may come and go: collective routing enables only
after stable capacity, drops on confirmed contraction, and can recover
later. Mesh-specific failures retry once through ordinary Auto.

This update also pins MeshLLM to a v0.73.1-compatible backport of
[MeshLLM #1074](https://github.com/Mesh-LLM/mesh-llm/pull/1074), so
client-only Buzz nodes cannot enter model election or download a remote
provider model. Buzz preserves the selected local sharing model and
switches an existing client to sharing across a controlled app restart,
retaining one runtime and one `:9337` / `:3131` pair per machine.

Validation:
- Full local `just ci` passes on the cleaned branch.
- MeshLLM host-runtime suite: 1,568 passed, 0 failed; strict Clippy
passes.
- Buzz desktop Tauri suite with `mesh-llm`: 1,721 passed, 0 failed;
strict feature Clippy passes.
- Playwright covers client-to-share using the saved local model and no
destructive stop.
- Packaged two-machine testing proved single-model routing, dual-model
collective routing, tool-markup fallback, and runtime reuse.
- Packaged client-only recheck routed a real Mini Buzz turn through M5
while Mini stayed `is_client=true`, `is_host=false`, hosted no models,
and created no Gemma cache.

Builds on the recovery work merged in #2823; this PR does not duplicate
it.

8eb6e3eb60 fix(agents): run live Databricks discovery instead of the fallback list (#2890)
## Problem

The Databricks model dropdown offers a handful of stale models — and
there's no way to tell that list apart from the real one. The AI Gateway
exposes **66** chat/embedding endpoints on `block-lakehouse-production`,
but the picker was showing a short list that includes models the gateway
no longer serves and embedding endpoints that can't chat at all.

Three independent defects, all on the discovery path:

**1. Live discovery never ran for agents with no saved provider.**
`get_agent_models` gates every in-process discovery attempt on the
provider (`is_openai_compatible_provider` / `is_anthropic_provider` /
`is_databricks_provider`), reading it straight from `record.provider`.
That field is `null` for every agent record created before provider
persistence — and for any agent that inherits its provider from the
build. So all three gates saw `None`, no HTTP discovery ran, and the
request fell through to the `buzz-acp models` subprocess. On the
Databricks path that subprocess returns `discovery_failure_fallback` —
the small hardcoded `DATABRICKS_V2_KNOWN_MODELS` catalog — which the
frontend renders exactly like a live catalog. An internal DMG that bakes
`BUZZ_AGENT_PROVIDER=databricks_v2` and a `DATABRICKS_HOST` still got
the fallback.

**2. The fallback list couldn't represent the running model.**
When discovery genuinely fails, the picker should at minimum be able to
show what the agent is actually configured with. For `DatabricksV2` it
couldn't: the fallback returned only the hardcoded slate, so a model
like `databricks-gpt-5-5` wasn't selectable in its own picker.

**3. Embedding endpoints were offered as chat models.**
`databricks-bge-large-en` was selectable (visible in the dialog today).
The v2 endpoints payload carries no `task` or `state` field, so there is
nothing to filter on but the name.

## Changes

- **`effective_discovery_provider`** (new,
`desktop/src-tauri/src/commands/agent_models_env.rs`) — an explicit
provider (saved record value, or the create/edit dialog's current form
value) still always wins; when there is none, discovery falls back to
the runtime's own provider env var (`GOOSE_PROVIDER`,
`BUZZ_AGENT_PROVIDER`, …) read off the merged env, which by that point
already carries the baked build floor and the process env. Wired into
both `get_agent_models` and `discover_agent_models`.
`SavedAgentModelDiscoveryConfig` now carries `provider_env_var` from
`known_acp_runtime`, so each runtime reads *its own* key rather than a
shared guess.
- The relay-mesh branches in `discover_agent_models` deliberately keep
using `input.provider`: those key off a deliberate provider selection,
never a baked default.
- **Asserted vs inferred matters for missing credentials.** The OpenAI
and Anthropic gates error on a missing API key, while the Databricks
gate falls through; an inferred provider hitting the first two would
have replaced a working subprocess catalog with `config:
ANTHROPIC_API_KEY required` (`export GOOSE_PROVIDER=anthropic` is
goose's documented way to pick a provider, and it keeps the key in its
own keyring). So `effective_discovery_provider` returns a
`DiscoveryProvider` that remembers how the value was resolved, and
`required_env` only reports a missing credential for an asserted
provider. A wrong guess declines and lets the subprocess answer.
- **`is_chat_capable_endpoint`** (new,
`crates/buzz-agent/src/catalog.rs`) — applied in
`parse_v2_endpoints_page`. Drops `*embedding*` and segment-matched `bge`
/ `gte` endpoints; keeps everything unrecognised (fail-open, so a new
model family is never hidden). Segment matching is why it's `split('-')`
and not `contains`: a substring check would swallow legitimate names.
- **`discovery_failure_fallback`** for `Provider::DatabricksV2` now
leads with the configured model (deduped against the known slate,
blank-tolerant), so a failed discovery still yields a picker that can
show the running model. The configured model is trimmed once up front —
`resolve_model` doesn't trim, so a padded `DATABRICKS_MODEL` used to
slip past the dedupe and appear twice.
- **`sort_v2_endpoints_newest_first`** (new, second commit) — the
catalog is now ordered newest-first on each endpoint's
`created_timestamp`, ties broken by name. Previously Buzz sorted
nothing, so the gateway's own order reached the picker: it pages in two
phases (Databricks-managed, then workspace-created — the page token
decodes to `{"phase":"user"}`), each alphabetical, which buried
`databricks-claude-opus-5` 8th behind five older Claude endpoints and
`goose-claude-opus-5` — the newest endpoint in the catalog — 55th of 63.
Sorting in `fetch_v2_models` means both discovery paths inherit it with
no wire or type changes, and the combobox filter preserves incoming
order. Endpoints with an absent or unparseable timestamp sort last
rather than first, so a wire-shape change degrades to "unordered at the
bottom" instead of "shuffled to the top".
- The name tiebreak is load-bearing: eleven managed endpoints share one
placeholder timestamp (`1699610000000`), so without it their relative
order would vary between runs. That placeholder is also not always
accurate — a few genuinely recent endpoints
(`databricks-kimi-k2-7-code`, `databricks-llama-4-maverick`) land at the
bottom with the 2023 batch. The gateway offers nothing better to sort
on.
- Env/provider lookup helpers moved out of `agent_models.rs` into
`agent_models_env.rs`. This keeps the command module under the file-size
limit **without ratcheting the override up** — the existing 1079 entry
is untouched (file is now 1066 lines).

## Verification

Live against `block-lakehouse-production`, release build:

```
BUZZ_ACP_AGENT_COMMAND=$PWD/target/release/buzz-agent \
BUZZ_AGENT_PROVIDER=databricks_v2 \
DATABRICKS_HOST=https://block-lakehouse-production.cloud.databricks.com \
DATABRICKS_MODEL=databricks-gpt-5-5 \
./target/release/buzz-acp models --json
```

- before: 66 endpoints, including `databricks-bge-large-en`,
`databricks-gte-large-en`, `databricks-qwen3-embedding-0-6b`
- after: **63** endpoints, `[.models[] | select(.id |
test("embedding|-bge-|-gte-"))]` → `[]`

Top of the list after the sort commit:

```
goose-claude-opus-5                2026-07-24
databricks-claude-opus-5           2026-07-23
databricks-gemini-3-6-flash        2026-07-20
databricks-gemini-3-5-flash-lite   2026-07-20
databricks-inkling                 2026-07-14
```

Tests: 15 new (8 in `catalog.rs` — including the two-wire-shape
timestamp parse, the sort's tiebreak/no-timestamp cases, and the
padded-model dedupe — and 7 plus one assertion in
`agent_models_tests.rs`, 3 of them covering the asserted/inferred
credential split), two existing tests updated. `just check`, `just
test-unit`, and `just desktop-tauri-test` all pass (1636 desktop-tauri
tests, 274 buzz-agent lib tests).

Not run locally: the Docker-backed integration suite (`just test`) —
this diff touches neither `buzz-relay`, `buzz-db`, nor `buzz-auth`.

## Follow-ups (deliberately out of scope)

Two inference-path defects found while investigating, both reproduced
live against the gateway and both independent of discovery:

1. **Gemini thought signatures are dropped.** The gateway returns a bare
`thoughtSignature` on tool calls; the external-model serving endpoints
return it nested as `extra_content.google.thought_signature`. Neither
shape is round-tripped, so multi-turn tool use on `databricks-gemini-*`
fails with a 400 on the second turn.
2. **Array-shaped `content` is silently discarded.** Some models return
OpenAI `content` as a block array rather than a string; `parse_openai`'s
`str_field` returns `None` and the text is dropped.

The legacy `serving-endpoints` path does not work around either one, and
costs reasoning support on the GPT-5 family.

Lee SalminenandGitHub 2a051a404d feat(relay): make per-owner community limit configurable via BUZZ_MAX_COMMUNITIES_PER_OWNER (#2599)
Closes #2600

## Summary

Self-hosted multi-tenant deployments (one relay serving many communities
via host-based tenancy) routinely need more than three communities owned
by the same operator identity. `MAX_COMMUNITIES_PER_OWNER` is currently
a hardcoded const, and hitting it surfaces as a `limit_reached` 409 from
`POST /operator/communities` — which provisioning UIs tend to mislabel
(mine reported it as "subdomain already taken").

This makes the limit configurable per deployment:

- New env var `BUZZ_MAX_COMMUNITIES_PER_OWNER` — read once per process,
must parse as a positive integer; missing/invalid/non-positive values
fall back to the existing default of **3**, so current deployments are
unaffected.
- Enforcement locations are unchanged and stay in the authoritative
relay-layer checks: community provisioning
(`create_community_with_owner`) and ownership transfer (inside the
advisory-lock transaction).
- Parse/fallback rules are extracted into a pure helper
(`effective_owner_limit`) with unit tests, keeping the cached getter
trivial.

## Test plan

- `cargo test -p buzz-db --lib` — new `owner_limit_*` tests cover
default, invalid, non-positive, and positive-override cases.
(Pre-existing unrelated failure on clean main:
`replica_fence::tests::fence_starts_closed_and_opens_on_advance`,
tracked in #2369.)
- `cargo clippy -p buzz-db --all-targets` and `cargo fmt` clean.
- Deployed on my multi-tenant relay (vibecode.casa) with
`BUZZ_MAX_COMMUNITIES_PER_OWNER=100`: provisioning a 4th community for
the same owner succeeds; without the var the stock limit of 3 still
applies.

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)

c26bf5945d fix(core): block IPv6 transition SSRF targets (#2801)
## Summary

- classify IPv4-compatible, IPv4-mapped, and SIIT IPv4-translated IPv6
addresses using the existing IPv4 SSRF policy
- decode IPv4 destinations under the RFC 6052 well-known NAT64 prefix
- conservatively block local-use NAT64, Teredo, and 6to4 ranges
- add boundary coverage for every newly handled transition prefix

## Why

The workflow webhook SSRF guard previously recognized IPv4-mapped IPv6
addresses but not other standardized IPv6 forms that can embed or route
to IPv4 destinations. Private, loopback, or link-local IPv4 targets
represented through those forms could therefore pass address
classification.

This also covers the legacy SIIT IPv4-translated prefix
(`::ffff:0:0:0/96`), which Rust's `Ipv6Addr::to_ipv4()` does not
recognize but an SIIT-enabled network may route to the IPv4 value in the
final 32 bits.

Network-specific NAT64 prefixes remain a deployment concern and should
be restricted through egress policy; they cannot be inferred generically
from an IPv6 address.

## Test plan

- `cargo fmt --all -- --check`
- `cargo test -p buzz-core network` (35 passed)
- `cargo clippy -p buzz-core --all-targets -- -D warnings`
- `git diff --check`

60a171b19e fix(workflow): bypass system proxies for webhooks (#2800)
## Summary

Disable automatic system-proxy discovery for workflow webhook requests.

## Why

Webhook destinations are resolved, validated, and pinned before the
request to prevent DNS-rebinding SSRF. If reqwest uses a system proxy,
the proxy can resolve the original hostname itself instead of connecting
to the validated address, bypassing that pinning guarantee.

Calling `no_proxy()` keeps these security-sensitive requests on the
directly validated connection path. Redirects remain disabled.

## Test plan

- `cargo fmt --all -- --check`
- `cargo test -p buzz-workflow --features reqwest` (149 passed)
- `cargo clippy -p buzz-workflow --all-targets --features reqwest -- -D
warnings`
- `git diff --check`

Shani SinghandGitHub 264a56a226 fix(audit): hash created_at at the precision Postgres stores (#2638)
Fixes #2637 — full analysis and reproduction there.

## Problem

Audit entries are stamped and hashed with `Utc::now()` (nanoseconds),
then stored in a `TIMESTAMPTZ` column (microseconds). `compute_hash`
covers `created_at.to_rfc3339()`, and chrono emits 0/3/6/**9**
fractional digits depending on the value — so the digest written at
`service.rs:103` is computed over `…T12:00:00.123456789+00:00` while
`verify_chain` recomputes over the `…T12:00:00.123456+00:00` that
Postgres hands back.

Every hash chain backed by a real database therefore fails verification
at its first entry, on untampered data. That is not just a broken
feature — it means a genuinely forged row is indistinguishable from the
permanent baseline failure, so `HashMismatch` carries no signal.

It is invisible in CI because all six chain tests are `#[ignore =
"requires Postgres"]`, and the in-process `hash.rs` tests use a fixture
timestamp of `2026-01-01T00:00:00Z` — zero sub-seconds, the one value
where the bug cannot appear.

## Solution

Reduce `created_at` to the stored precision *before* hashing, so the
in-memory entry and the row are byte-identical:

```rust
pub fn to_storage_precision(created_at: DateTime<Utc>) -> DateTime<Utc> {
    created_at.trunc_subsecs(6)
}
```

`log_inner` is the only place that assigns `created_at` — every caller
goes through `NewAuditEntry`, which carries no timestamp — so this is a
single choke point. It is wrapped in a `log_timestamp()` helper purely
so the invariant is assertable without a database.

I chose truncation at the write path over the alternative (hashing a
precision-independent encoding such as
`timestamp_micros().to_be_bytes()`). Both fix the mismatch, but
truncating keeps the existing hash preimage format and gives the
stronger invariant: the `AuditEntry` returned from `log()` is now
exactly what a later read returns.

Truncation matches what actually happens on the wire — sqlx encodes
`DateTime<Utc>` as microseconds since the Postgres epoch, truncating —
so the value hashed is the value stored.

## Validation

Toolchain note: built on Windows with the `x86_64-pc-windows-gnu`
toolchain (no MSVC linker locally).

**Before**, against Postgres 17 with `migrations/*` applied:

```
$ cargo test -p buzz-audit --lib -- --ignored --test-threads=1

test service::tests::chain_links_within_one_community ... FAILED
test service::tests::chains_are_independent_per_community ... FAILED
test service::tests::community_chain_starts_at_seq_1_with_null_prev ... ok
test service::tests::cross_community_row_does_not_verify ... ok
test service::tests::verify_detects_tampering_within_a_community ... FAILED
test service::tests::verify_empty_range_is_false ... ok

test result: FAILED. 3 passed; 3 failed
```

with `HashMismatch { seq: 2 }` / `HashMismatch { seq: 1 }` on untampered
chains.

**After**, same database:

```
test result: ok. 6 passed; 0 failed
```

`verify_detects_tampering_within_a_community` is the one to look at: it
asserts `HashMismatch` lands on the *tampered* entry's `seq`. It was
failing because verification already blew up on an earlier untampered
row — so the assertion proving tamper detection works had never actually
been exercised. It passes now.

Also:
- `cargo test -p buzz-audit --lib` (no Postgres) — 12 passed, 0 failed.
- `cargo clippy -p buzz-audit --all-targets -- -D warnings` — clean.
- `cargo fmt -p buzz-audit -- --check` — clean.

## New tests

Three in `hash.rs`, none needing Postgres:

- `storage_precision_drops_sub_microsecond_digits` — the helper's
contract, and that it is idempotent so a re-read value is unchanged.
- `nanosecond_timestamps_cannot_survive_a_database_round_trip` — asserts
the digests **differ**. This is the trap itself, written down so the
next person changing the hash preimage sees why the precision reduction
is load-bearing.
- `storage_precision_timestamps_survive_a_database_round_trip` — the
invariant the write path must hold.

Plus `log_timestamp_carries_no_sub_microsecond_digits` in `service.rs`,
deliberately **not** `#[ignore]`d, so a regression on the write path is
caught by `just test-unit` instead of only by Postgres-gated tests that
normally never run.

## Compatibility

Rows written before this stay unverifiable — they always were — so there
is no migration. An operator relying on an existing chain has to
re-anchor.

## Relationship to #2620

#2620 proposes a shared `verify_entries` walk (anchoring, seq
contiguity, tail-truncation detection) plus a `buzz-admin audit verify`
command. Its Postgres-free unit tests build entries in memory and would
pass regardless, but its `#[ignore]` Postgres tests and the operator
command itself would fail on every real chain until this lands. Worth
taking this first so that work has a verifiable baseline — the two
changes don't overlap in code.

0a9c26ee8c fix(acp): dead-letter auth errors immediately with re-auth hint (#2751)
## Problem

Auth-class errors (expired OAuth token, HTTP 401) are non-retryable: the
token won't self-repair between attempts. Today, `PromptOutcome::Error`
for an application-class error falls into the generic `queue.requeue()`
path, burning up to 10 retry slots over a long backoff window before
dead-lettering. Will's canary run observed the 401 message being retried
repeatedly.

## Solution

Add `is_auth_error()` that classifies `AcpError::AgentError` messages
matching two narrow patterns observed in the field:

- `"Re-authenticate"` — emitted by the Claude CLI for expired OAuth
tokens
- `"API Error: 401"` — present in Claude/Codex HTTP-401 responses

Conservative matching is intentional: a false positive (misclassifying a
transient error as non-retryable) silently drops a user message, which
is worse than a false negative (extra retries on an auth error).

In `handle_prompt_result`, a new branch intercepts the failing batch
before `queue.requeue()` for auth-class errors and dead-letters
immediately, posting a user-visible notice to re-authenticate the CLI
(e.g. `claude /login` or `codex login`).

The transport/application split in `PromptOutcome::Error` is untouched —
this only changes batch fate after an application-class auth error.

## Tests

6 new tests in `error_outcome_emission_tests`:
1. `is_auth_error` matches `Re-authenticate` message
2. `is_auth_error` matches `API Error: 401` message
3. `is_auth_error` rejects other `AgentError` messages (usage credits,
etc.)
4. `is_auth_error` rejects transport errors (I/O, WriteTimeout)
5. Auth error dead-letters immediately — 0 pending channels after
`handle_prompt_result`
6. Non-auth application error still requeued — 1 pending channel after
`handle_prompt_result`

Full `cargo test -p buzz-acp`: 598/598 passing.
