3e3d80a27d fix(workflows): bind agent delegation to owner signatures (#5871)
🤖
## Summary

Workflow messages still wake the managed agent named by their
owner-signed definition, but the relay is now only a doorbell. It
carries pointers to the exact workflow revision and cause; ACP
independently verifies those signed artifacts, reconstructs trigger
input, and renders the prompt locally. Relay-authored prose is never
shown to the agent or treated as owner authority.

Before this change, a compromised relay signing key could attach
`workflow-owner` to chosen message content. After this change, ACP
grants the workflow owner principal only when the doorbell, owner-signed
kind `30620` definition, referenced step, channel, and cause all verify.
Invalid workflow-shaped deliveries are dropped rather than falling
through as ordinary relay messages.

### Doorbell behavior

- Workflow rows retain the exact kind `30620` event ID that materialized
them. Existing rows remain nullable and fail closed until the definition
is saved again.
- Relay events contain the definition event/step and one typed cause:
signed event, signed manual command, deterministic schedule slot, or
webhook cargo.
- ACP refetches and verifies the owner-signed definition. It also
refetches signed event/command causes, reconstructs their trigger
context, rechecks that the signed trigger matches the definition,
validates exact cron/interval slots, and renders `send_message` text
itself.
- Manual commands from an agent's cryptographically verified human owner
remain authorized, but command JSON deliberately no longer populates
arbitrary webhook fields. Unrelated channel members remain denied. If
parameterized manual runs are added later, those parameters must return
as explicitly untrusted cargo under the same boundary as webhooks rather
than inheriting owner authority.
- Prior workflow-step outputs cannot be independently reconstructed, so
`send_message` templates and conditions that depend on them fail closed
rather than treating unresolved placeholders as owner-authorized text.
- Mention wake targets are resolved only from the owner-signed template.
`@Name` text arriving through a signed source event or webhook field
cannot steer a different agent.

### Webhooks and replay controls

Webhooks have no signed source event. Their JSON therefore travels as
explicitly untrusted external cargo, can fill only `{{trigger.*}}` slots
declared by the owner-signed template, and is labelled as untrusted in
the prompt. ACP applies a per-definition token bucket (five immediate
turns, refilling at five per minute) and caps serialized cargo at 61,440
bytes.

Signed event, command, and schedule causes are deduplicated by
definition revision × semantic cause. Dedupe is intentionally
process-lifetime/in-memory: an ACP restart can admit a replay again.
Schedule causes must be exact authorized cron occurrences or interval
boundaries; wall-clock freshness/skew policy is deferred.

### Rollout

This is a coordinated protocol change. New ACP drops old relay workflow
messages because they lack the `doorbell-v1` pointer shape. Old ACP does
not recognize new doorbells as delegated owner messages, so owner-only
policy rejects them. Existing database rows without a definition event
ID do not fire a doorbell until the workflow is re-saved.

### Related issue

Security correction stacked directly on #2737. The owner-trigger
authorization in #5854 remains separate and will be restacked after this
correction merges into #2737.

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

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

## Validation

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

## Remaining gate

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

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

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

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

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

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

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

## What whole-community V1 removes

For the target community, V1 removes:

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

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

## Safety model

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

### 1. Inventory and approval

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

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

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

### 3. Checkpointed destruction

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

### 4. Independent verification

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

## What V1 deliberately does not erase

### Shared content-addressed storage

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

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

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

### External retained copies

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

### Member-only erasure

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

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

## In scope

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

## Deferred / not covered

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

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

## Validation

### Current PR head and repository state

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

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

Source validation on this exact SHA passed:

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

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

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

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

- source: `928992237358a3294621ac0280830b77155abc04` (**prior head**)
- image: `buzz-e2e:sha-928992237358`
- immutable image digest:
`sha256:a1a204f4618ac22d9e210be5e5290645a15d79831ae30b0e44379357c8e4a895`
- evidence root:
`/tmp/buzz-e2e/20260807T033025Z-928992237358-full-gates/`
- evidence-manifest digest:
`82875c5bc9bea7370b796a7aef3457b3a1c8306c84c59e0f7388bbb5ad30e865`

Passed gates at that prior head:

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

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

### Prior-head cleanup

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

Jordan MecomandGitHub 885bed35ee fix(workflow): bind trigger author to the signed event (#4607)
This change derives `trigger_author` exclusively from the signed event
pubkey. Actor tags remain available as event data but cannot override
the identity used by author-sensitive workflow conditions.

This removes the impersonation path without changing workflow
definitions or requiring stored-data migration.

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

| 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

- SEC-005 module incl. PG behavioral matrix: 8/8 (removed-member,
never-member, owner-no-bypass, deleted-30617, malformed/ambiguous

- 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.

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`
