ci(audit): ignore RUSTSEC-2026-0459, unlinked libsqlite3-sys advisory

The advisory covers bundled SQLite in libsqlite3-sys 0.30.1, which sits in
Cargo.lock only because sqlx resolves sqlx-sqlite unconditionally. sqlx builds
postgres-only, so the bundled C source is never compiled or linked. The fix
needs libsqlite3-sys >= 0.39 but sqlx-sqlite 0.8.6 pins ^0.30.1; the waiver is
documented to retire if the sqlite feature ever enters the build.

 | `GITLAWB_REQUIRE_SIGNED_PEER_WRITES` | Require peer writes to prove their DID on every transport: RFC 9421 signatures on the announce/sync routes, and an Ed25519 payload signature on gossip ref-update events. Defaults to `false` during the staged rollout below. Upgrade every gossip publisher before enabling, or their updates are dropped with no error on their side. |
 | `GITLAWB_ENFORCE_OWNER_PUSH` | Require the authenticated pusher to be the repo owner on `git-receive-pack`. **Defaults to `true`.** A `did:key` signature is authentication, not authorization (anyone can mint a key and sign), so with this off every signed caller may push to every repository, private ones included. Delegated and CI keys count as non-owners: a UCAN `git/push` capability is verified but not yet honored for authorization, so they cannot push while this is on. Set `false` only for a rolling upgrade; see [`docs/RUN-A-NODE.md`](docs/RUN-A-NODE.md). |
 | `GITLAWB_AUTO_SYNC` | Enable automatic sync from known peers. |
+| `GITLAWB_RECONCILIATION_SWEEP` | Enable the hourly durability sweep that re-pins/backstops missing objects (default `true`; disabled when no IPFS/Pinata backend is configured). Public pin repair runs against any configured backend (IPFS, Pinata, or both). Encrypted recovery repair requires local IPFS (`GITLAWB_IPFS_API`); Pinata-only nodes reconcile public pins only. |
 | `GITLAWB_MAX_PACK_BYTES` | Max git pack body size for smart-HTTP routes. |
 | `GITLAWB_GIT_SERVICE_TIMEOUT_SECS` | Max seconds a served git upload-pack, receive-pack, or `info/refs` advertisement may run before it is aborted (504). Default 600. Also bounds the withheld-blob classification walk (on both the upload-pack serve and receive-pack replication paths) and the push-side pin-candidate discovery (`rev-list` / `cat-file`), each reaped via process-group teardown at the deadline. On the path-scoped upload-pack path the classification walk and the pack serve share ONE deadline, so this value bounds their combined duration rather than granting each stage a full budget: a walk that consumes it leaves the serve nothing and the clone gets a 504. Serving large path-scoped repos may therefore need a higher value than they did when each stage was budgeted separately. Accepted range is 1 to 3153600000 (100 years), since the node derives deadlines from this value and a larger one cannot be represented. |
 | `GITLAWB_GIT_ACQUIRE_TIMEOUT_SECS` | Max seconds the storage-acquisition phase (Tigris HEAD/GET, push advisory-lock) of a served git op may run before the request is shed with a 503, separate from the git-run timeout. The concurrency permit is released on expiry so a stalled backend cannot pin the pool. Default 30. |

+/// A captured per-repo visibility-policy epoch that fences a pin batch.
+///
+/// The reconciliation sweep reads the epoch immediately before dispatching a
+/// pin loop and passes a fence in; the loop re-reads the epoch before every
+/// upload and aborts the batch the moment it moves. A visibility narrow that
+/// lands mid-batch (a rule made private, a repo quarantined) must not let the
+/// remaining pre-authorized objects still go to a public content-addressed
+/// backend — the narrow is a policy change, and dispatching against the stale
+/// snapshot is the exact irreversible-publication class this fence exists for
+/// (R1-P1). `None` (the push path) means "no fence": the push derives its own
+/// object list at admission and holds a write lease, so no sweep-style batch
+/// snapshot crosses the dispatch boundary.
+///
+/// The fence deliberately does NOT hold any lock across the batch: a
+/// visibility narrow (rule insert/remove, quarantine set) must commit
+/// immediately, and the batch aborts on its next `is_current` check. Holding
+/// a per-repo mutex from capture through drop would invert this — the narrow
+/// would block behind the background sweep and every object in the batch
+/// would still be sealed/posted to the reader being removed. The accepted
+/// residual is a single in-flight object: a narrow that commits between the
+/// pre-POST `is_current` check and the HTTP POST cannot be recalled, but the
+/// next iteration aborts and the fenced DB record (row-locked against the
+/// narrow's epoch bump) refuses to land the raced row as durable.
+/// Multi-process / multi-node narrows are ordered by the same epoch column;
+/// no in-process registry is involved.
+///
+/// Product decision (revocation model): prompt revocation wins over
+/// publication atomicity. The suite intentionally allows one provider
+/// upload already in flight when a rule narrows and requires every
+/// LATER object to stop (`encrypt_and_pin_stops_sealing_when_reader_
+/// removed_mid_batch`). A stronger contract — revocation commit
+/// linearizing against every concurrent publication, or compensation
+/// (unpin/delete) for an envelope that finishes after removal — is
+/// explicitly OUT of scope until decided and documented here. Do not
+/// reintroduce batch-spanning mutual exclusion to close the
