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.

 ## Toolchain and CI reality

 - MSRV is Rust 1.91 (`rust-version` in the workspace `Cargo.toml`). The MSRV CI job runs `cargo check --workspace --all-targets` on exactly 1.91, so check that an API you rely on is stable there; the full test suite runs on stable.
- The PR workflow's jobs are `cargo fmt --check`, `cargo clippy --workspace --all-targets -- -D warnings`, `cargo test` (against Postgres), a release build, `cargo audit`, the MSRV check, and a Docker build. On a PR, `scripts/ci-surfaces.sh` runs each job only when the PR touches its inputs, and scopes `cargo test` and the release build to the touched crates plus every crate that depends on them. Root `Cargo.toml`/`Cargo.lock`/`.cargo/` changes run the Rust jobs (fmt, clippy, tests, release build, MSRV) on the whole workspace; every other job still runs only when its own inputs change. Edits to the CI wiring itself (`pr-checks.yml`, `codeql.yml`, `scripts/ci-surfaces.sh`), push to `main`, and the merge queue run every job on the whole workspace. Edits to any other workflow run none of these jobs on a PR; CodeQL only analyzes them as Actions code. Run `cargo test --workspace` locally regardless. The same script limits CodeQL (`codeql.yml`) to the languages a PR touches. The `main` branch ruleset currently requires one approving review but does not require these checks to pass before merge; a failing job should block review approval in practice, but nothing enforces that mechanically today.
+- The PR workflow runs these jobs on every PR: `cargo fmt --check`, `cargo clippy --workspace --all-targets -- -D warnings`, `cargo test --workspace` (against Postgres), a release build, `cargo audit`, the MSRV check, and a Docker build.

 # Changelog

-## [0.8.0](https://github.com/Twigpine/node/compare/v0.7.1...v0.8.0) (2026-11-10)
-
-
-### ⚠ BREAKING CHANGES
-
-* **node:** pending_ref_transitions.first_ref_name is dropped. Callers that read or write that column must move to receive_pack_requests.accepted_ordinal.
-* **node:** gate agent-task reads behind visibility rules ([#553](https://github.com/Twigpine/node/issues/553))
-* **node:** the GraphQL `repos` field now returns an error instead of the full list when more than MAX_VISIBLE_REPO_PAGE_SIZE (200) repositories are visible; larger lists must use `reposPage` with `limit`/`after`. Repository names are additionally limited to 100 bytes at creation, fork, and mirror-registration time.
-* **node:** gl cert show <id> --verify now requires --expect-node <did>; the node's self-reported DID is no longer trusted as a cert anchor.
-* **node:** `git-receive-pack` now rejects a push whose authenticated DID is not the repo owner, returning 403 before any ref update is applied. Delegated and CI keys count as non-owners: a UCAN `git/push` capability is verified but not yet honored for authorization, so an agent pushing under its own DID cannot push while this is on. Set `GITLAWB_ENFORCE_OWNER_PUSH=false` during a rolling upgrade, or have automation push as the repo owner, until scoped collaborator / UCAN-delegated push rights land.

 - UCAN proof chains are validated when supplied, but UCAN capabilities are not consulted by write authorization and the root issuer is not independently trust-anchored. UCANs therefore do not yet grant scoped collaborator access.
 - Agent lifecycle revocation is not enforced by HTTP Signature authorization; do not rely on removing or revoking an agent record to block a compromised signer.
- Task list/get reads (REST and GraphQL) are repository/task-gated and omit `ucan_token`. Slash-form `repo_id` rows (mirror-hosted tasks) can appear on list for the delegator or trimmed assignee, but `GET /api/v1/tasks/{id}` and GraphQL `task` fail closed for every caller because there is no local repository backing to serve. Read visibility is not a blanket data-classification boundary: IPFS-pin and Arweave-anchor listings are not repository-gated; withheld path names can be visible to a root reader; and later visibility changes cannot retract content already announced or externally anchored.

 | `GITLAWB_IPFS_REQUEST_BUDGET_SECS` | Absolute wall-clock budget for one admitted `/ipfs/{cid}` request's acquire+walk lifetime. Per-stage clamps bound the acquire and walk stages to the remaining budget, and no stage starts once it is exhausted; the scan then stops with a retryable 503. The object-type probe and content-read `cat-file` subprocesses are budget-checked before starting and each also run under their own deadline (the lesser of `GITLAWB_GIT_SERVICE_TIMEOUT_SECS` and the remaining budget), reaped via process-group teardown, so a hung `cat-file` cannot hold the request's walk slot past it. One hang path is still unbounded: the probe's object-store readability check is a plain filesystem sweep with nothing to reap, so a wedged filesystem can hold the slot past the deadline. Default 600. Accepted range is 1 to 3153600000 (100 years), since the node derives a deadline from this value and a larger one cannot be represented. |
 | `GITLAWB_IPFS_RESOLVE_BUDGET_SECS` | Shorter budget for the pre-walk CID resolve inside an admitted `/ipfs/{cid}` request: the lookup that maps the requested CID to its git oid(s), which runs while the scarce walk admission is already held. A well-formed CID with no pin row does no probe and no walk work, so without this it could hold a walk slot for the whole request budget while nothing walked, and enough such requests shed every real retrieval at admission. The effective deadline is the lesser of this and the remaining request budget, so a value above `GITLAWB_IPFS_REQUEST_BUDGET_SECS` degrades to the request budget. Only the resolve is on this clock; walk and probe work stay on the request budget, so a slow but progressing scan is never shed by it. Default 10. Accepted range is 1 to 3153600000 (100 years). |

Authentication is not authorization on its own, since anyone can mint a `did:key` and sign, so owner enforcement is the only thing that prevents every signed caller from pushing to every repository, including private ones.

 - **Mitigation:** `GITLAWB_ENFORCE_OWNER_PUSH=false` is the explicit rolling-upgrade compatibility override. Disable it only for the duration of an upgrade whose pushers are not yet the repo owner, then turn it back on. 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.

 ### Private repository reads
 - Repository and path-scoped visibility checks are enforced for repository API and Git content reads. A denied whole-repository or root read returns the same 404 shape as a missing repository, so the denial does not reveal private-repository existence.
 - Sparse-clone support exposes withheld path globs to callers who may read the repository root. Do not put sensitive information in withheld path names.
- Task list/get reads (`GET /api/v1/tasks`, `GET /api/v1/tasks/{id}`, and GraphQL `tasks` / `task` over HTTP and WebSocket) are repository/task-gated through shared visibility collectors and omit `ucan_token`. Slash-form `repo_id` rows (mirror-hosted tasks) can appear on list for the delegator or trimmed assignee, but `GET /api/v1/tasks/{id}` and GraphQL `task` fail closed for every caller because there is no local repository backing to serve. All of those transports share the same per-IP `GITLAWB_TASK_READ_RATE_LIMIT` budget. `/api/v1/ipfs/pins` and `/api/v1/arweave/anchors` are not repository-gated; pin and anchor listings expose object and ref metadata.
+- `GET /api/v1/tasks`, `/api/v1/ipfs/pins`, and `/api/v1/arweave/anchors` are not repository-gated. Task records include a UCAN token; pin and anchor listings expose object and ref metadata.
 - Changing a repository's visibility controls future serving, but cannot retract ref metadata or configured external pins and anchors already announced while the repository was public. Do not push secrets to an announceable repository.
 - **Impact:** Visibility policies protect the repository and Git content routes they gate, not every metadata endpoint or previously published content.
 - **Remaining boundary:** This read control does not address the independent write-authorization and UCAN-delegation limitations described above.

 ## Threat Model

 Twigpine is designed to be secure against:
- **Unauthenticated writes:** HTTP Signature auth on protected write endpoints; see Known Limitations for owner and capability authorization gaps
- **Tampered git objects:** CIDv1 content addressing detects modification
- **Identity spoofing:** DIDs derived from public keys, unforgeable without the private key
- **Centralized takedown:** no single point of control; data on IPFS + Arweave

-//! Opaque, integrity-protected continuation tokens for the task read surfaces.
-//!
-//! The task list pages by keyset over `(created_at, id)`, but the rows a
-//! caller may *see* are a filtered subset of the rows the query has to
-//! *examine*. Handing the caller a raw `(created_at, id)` cursor therefore
-//! forced a choice between two broken options (#327 review): anchor the cursor
-//! on the last visible row, and a window of denied tasks longer than the scan
-//! budget stalls paging forever; or anchor it on the last examined row, and a
-//! denied read leaks the id and timestamp of a task `GET /tasks/{id}` other-
-//! wise 404s.
-//!
-//! A server-issued token removes the choice. The position it carries is the
-//! last *examined* candidate, so paging always advances, and the payload is
-//! opaque and MAC'd, so the caller learns nothing from it and cannot forge one
-//! naming a row of their choosing.
-//!
-//! The position must be *confidential*, not merely unforgeable: a token that
-//! merely signed a base64 payload would still let its holder read the id and
-//! timestamp of the denied row it names, which is the disclosure the token
-//! exists to prevent. The payload is therefore encrypted under a
-//! synthetic-IV construction (SIV): the tag is an HMAC over the filter and the
-//! plaintext, and it doubles as the IV seeding the keystream the plaintext is
-//! XORed with. That needs no randomness source and no dependency beyond the
-//! `hmac`/`sha2` pair already used for webhook signatures and blob recipient
-//! tags, and it is decrypt-last: nothing is parsed until the tag verifies.
-//!
-//! Making the token the *only* accepted cursor also fixes the ordering-domain
-//! bug the same review found. `agent_tasks.created_at` is TEXT and compared as
-//! TEXT, so `...Z` and `...+00:00` denote one instant but sort differently. A
-//! caller-typed timestamp could silently skip or repeat same-time rows. The
-//! token instead carries the stored string verbatim, so the value compared is
-//! always a value the server wrote.
-//!
-//! A token is bound to the *caller* as well as the filter. The position it
-//! names is the last examined candidate, not the last visible one, so it
-//! encodes how far a scan got under one caller's visibility. Resuming it as a
-//! different caller would start the scan past rows that caller is entitled to
-//! read, silently dropping them from the answer (#327 review). The presenting
-//! caller's normalized DID (empty and flagged absent when anonymous) is
-//! therefore part of the MAC input, so a token presented by anyone else fails
-//! to verify rather than under-reporting.
-//!
-//! Wire form: `v1.<iv>.<body>`, both parts base64url unpadded: the 16-byte
-//! synthetic IV (the truncated MAC, which also seeds the keystream) and the

-/// the raw-content CID. The opportunistic repair on the pin path only fires when a push

-/// The push gate (repos.rs) must deny:

-///    to git receive-pack, and git accepts refnames with bytes >= 0x80; the gate
-///    never sees these refs, no durable child row exists, and under requests/issues/
-///    the lossy for-each-ref decode still matches the narrowed exemption).
-/// 2. The bare `refs/gitlawb` name (the `starts_with("refs/gitlawb/")` check misses it).
-///
-/// Every explicit pre-git refusal must call `refuse_receive_pack_before_git` to
-/// terminalize the intent aggregate in one transaction, or a dropped future between
-/// the intent insert and `receive_pack` strands a `received` + `prepared` aggregate
-/// that is never purged, never promotable, and poisons its tuple.
-///
-/// The visibility exemption (visibility_pack.rs) was narrowed to `requests/` and
-/// `issues/` only. The push gate is the premise that narrowing relies on (the comment
-/// at visibility_pack.rs:340), so tests must prove:
-/// - A `refs/gitlawb/<other>` ref pointing at a blob is denied on push.
-/// - A stray `refs/gitlawb/<other>` blob ref planted in the pack path fails closed.
-///
-/// Source gates below pin the wiring; behavioral proofs live next to the code:
-/// `parse_ref_updates_refuses_non_utf8_command_line` and
-/// `internal_namespace_gate_covers_bare_name_and_subtree` (api/repos.rs),
-/// `planted_non_exempt_gitlawb_blob_ref_fails_closed` (git/visibility_pack.rs),
