fix(storage): path-traversal barrier for sibling paths; restore the F4 unlock shape

Two CI failures from the storage-abstraction merge, both in this layer.

CodeQL (rust/path-injection). Every path derived from a repo path — the
pending-upload marker, its rename-temp, and the swap phase's .bak- and
.tmp-extract. work dirs — is rebuilt with join/with_file_name, and a rebuilt
path is a new question no earlier validation answers. Add
validated_sibling_path (single-segment name, containment under the repo
parent, explicit Component::Normal walk) and validated_repo_path_in (the same
walk for a repo path arriving as a parameter, applied where the filesystem
work happens rather than trusted across a call boundary), then route every
marker/backup/temp construction and the sweep's entry-derived repo paths
through them before any fs call. pending_upload_marker is fallible as a
result; the cleanup paths that cannot propagate treat a rejected path as
"no marker", the same conservative answer they already give for an absent one.

INV-22 F4 gate. The merge moved the advisory unlock from
RepoWriteGuard::release into LockedConn::unlock and, in doing so, took the
connection out of self BEFORE awaiting pg_advisory_unlock — the exact shape
#174 F4 forbids, since a cancellation mid-await then leaves Drop with
conn == None and strands the session lock. Restore the reviewed shape: unlock
through the still-owned connection, dispose of it only when the unlock errors
(#174 F3b), and set the new released flag only once the await resolves so the
Drop backstop stays live until then. tests/inv22_gates.rs follows the code to
its new home rather than being deleted with it; the invariant is unchanged.

 ## 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. 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.
 - Conventional commit titles (`feat:`, `fix:`, `docs:`, ...) are required by convention and drive releases, but no CI job checks them; a bad title fails review, not the pipeline.

 # 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.

 `POST /api/v1/sync/trigger` is not part of the staged rollout: it always requires a signature in both config modes and returns 401 without one, because each call drives an O(peers) outbound fan-out.
 
-The flag is not HTTP-only. It also gates inbound gossip ref-update events on the libp2p mesh, which carry an Ed25519 payload signature rather than RFC 9421 headers because there are no HTTP headers to sign. Set to `true`, an unsigned gossip event is dropped. Set to `false`, an unsigned event is accepted with a warning during the rolling-upgrade window, and the write budget it consumes is charged to the forwarding peer rather than to the DID it claims, since an unsigned event's claimed DID is asserted and not proven. A present-but-invalid signature is refused in both modes; that is forgery, not an un-upgraded peer.
-
-Because the flag now spans both transports, the rollout order matters in one direction: **upgrade every gossip-publishing peer to a build that signs events before you set this to `true`.** Enabling it while an old publisher is still live drops that publisher's ref-updates on arrival, and the publisher sees no error, because gossip has no response to carry one. Upgrading the HTTP peers alone is not sufficient.
-
-There is a second precondition on gossip ingest that the flag does not control. A publisher's `node_did` must already exist in the receiving node's peers table, or the event is dropped as an unknown peer DID. This holds in both modes, signed and unsigned alike: a valid signature proves key possession, not membership. Rows reach that table over HTTP, either from `GITLAWB_BOOTSTRAP_PEERS` when this node contacts a bootstrap peer and records the DID it reports, or from a prior `POST /api/v1/peers/announce`. So a peer that only ever joined the libp2p mesh, with no HTTP announce and no bootstrap contact in either direction, will have its ref-updates dropped even with a good signature and the flag off. If gossip is silently not landing from a peer you can see on the mesh, check that its DID is in `GET /api/v1/peers` on the receiving side first.

Must name a key file inside a directory, such as `/data/keys/p2p.key` or `./keys/p2p.key`. Two kinds of problem are handled differently. A value that cannot name a securable key file at all (a bare filename, `..` traversal, a trailing `/`, the filesystem root, or a `~/` path that escapes home) is refused before the node binds, so the process exits. Anything wrong with the storage itself (a symlinked or non-directory parent, an unsafe ancestor or working directory, an unreadable or malformed key) leaves p2p off while HTTP keeps serving; the node logs it at error level as `p2p_identity_key_load_failed` and sets the `gitlawb_p2p_identity_key_load_failed` metric to 1. Note that `/health` still reports healthy in that state, so alert on the log event or the metric rather than on the health check. Correcting the storage and restarting restores the same PeerId. On Unix a new key is created `0600` inside a `0700` directory. A key directory that grants access beyond its owner is tightened to `0700` on start; one that is closed too far is refused with a `chmod 700` remedy rather than widened, since a directory locked down on purpose is an operator decision. Rotate the key only when the node logs that the directory was group- or world-writable (or the key file itself was group- or world-readable). An ordinary `0755` directory is tightened too, but others could not read a `0600` key or replace its directory entry. An existing key file is never modified: one with group or other bits set is rejected (`chmod 600`), and so is one this node cannot read. On other platforms no permissions are enforced.

 Legacy-pin window: releases before the CID-resolver work stored the provider CID (Kubo dag-pb / Pinata) as a pinned object's resolver key. The `/ipfs/{cid}` resolver now recomputes the raw-content CID from the object bytes and refuses to serve a key that does not match, so `GET /api/v1/ipfs/pins` can still advertise an unrepaired legacy CID that 404s. Such a row is repaired opportunistically the next time a push carries the object again (its key is rewritten to the raw CID, the old value kept in `legacy_provider_cid`), but git negotiation omits objects the node already has, so most legacy rows never re-enter a push delta. A deferred one-shot startup sweep, not this opportunistic path, is what fully retires the advertise-then-404 window. Rows whose object bytes are gone stay withheld.

-  the suffix keep working untouched.
-- `GITLAWB_P2P_KEY` must name a key file inside a directory, such as
-  `/data/keys/p2p.key` or `./keys/p2p.key`. A bare filename is refused at
-  startup, since the node will not keep its identity key in the working
-  directory.

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.
+- `git-receive-pack` verifies HTTP Signatures, but `GITLAWB_ENFORCE_OWNER_PUSH` defaults to `false` for compatibility during rollout.
+- **Impact:** With the default setting, a valid signature authenticates the pusher but does not require that DID to be the repository owner.
+- **Mitigation:** Set `GITLAWB_ENFORCE_OWNER_PUSH=true` on nodes where owner-only pushes are required. Confirm that every legitimate pusher uses the owner DID before enabling it.
 
 ### UCAN delegation and revocation
 - The middleware validates a supplied UCAN's complete proof chain, but a root token is accepted without an independently trusted issuer anchor. `Ucan::can` is not yet used by write handlers, so a UCAN does not grant scoped repository access.

 ### 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.

-- **Tampered git objects:** CIDv1 content addressing detects modification
-- **Identity spoofing:** DIDs derived from public keys, unforgeable without the private key

-//! ## Replay
-//!
-//! A certificate proves *who* asserted a ref update and *what* they asserted.
-//! It does not prove the assertion is fresh. [`RefUpdateBody::seq`] and
-//! [`RefUpdateBody::nonce`] are inside the signed bytes (see
-//! [`RefUpdateBody::to_signing_bytes`]), so a verifier can trust the values,
-//! but deciding whether a nonce is being reused or a `seq` is going backwards
-//! needs state.
-//!
-//! This crate is deliberately stateless — it is embedded in both nodes and
-//! clients — so replay is **not** enforced here and cannot be. Ownership of
-//! the check sits with the verifier that accepts and persists certificates,
-//! which must:
-//!
-//! - reject a `nonce` it has already accepted for the same `(repo, ref_name)`;
-//! - reject a `seq` that does not advance past the last accepted `seq` for
-//!   that `(repo, ref_name)`.
-//!
-//! Until such a verifier exists, replay of ref-update certificates is not
-//! enforced anywhere in this workspace. This contract exists so the first one
-//! inherits the requirement instead of re-deriving it.

-//! 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.
-//!

-//! The publication boundary: WHO wrote, and HOW FAR that write got.
-//!
-//! Four lifecycle defects on this branch shared one root cause. A resource was
-//! tracked by a coarse state — "release started", "the path exists", "a row with
-//! this name exists" — when the safety question was about the IDENTITY and the
-//! PUBLICATION STAGE of one specific write attempt. A tail replicated refs from
-//! an attempt that had not dispatched a PUT; a read served a tree whose
-//! generation nobody had confirmed; a fork claimed a concurrent attempt's row and
-//! deleted a successor's object; a response-loss failure was compensated as if it
-//! proved non-publication.
-//!
-//! This module is the vocabulary that makes those questions answerable, and it is
-//! deliberately free of any object-storage type:
-//!
-//! - [`PublishAttemptId`] — minted before the request is built, carried with the
-//!   bytes as user metadata, read back off the store to decide whether what is
-//!   published is THIS attempt's work.
-//! - [`PublishStage`] / [`PublishStageCell`] — how far one attempt got, observable
-//!   from outside the future that is performing it, so a CANCELLED attempt can
-//!   still be classified.
-//! - [`UploadError`] — what the client KNOWS about dispatch and commit, not just
-//!   which HTTP status came back. Destructive compensation is licensed only by
-//!   [`UploadError::proves_not_published`].
-//!
-//! # Porting note (#79)
-//!
-//! PR #79 (`feat/storage-abstraction`) deletes `git/tigris.rs` and replaces it
-//! with a `BlobStore`/`RepoArchive` layer. Everything in this file is
-//! backend-agnostic on purpose and is meant to survive that swap unchanged: a new
-//! backend supplies its own error classifier (the one in `tigris.rs` is a single
-//! private function) and keeps these types as the contract its callers read.

-/// (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;

-/// explicitly OUT of scope until decided and documented here. Do not

+//! IPFS (content-addressed) blob backend over a Kubo node's Mutable File System.
+//!
+//! Kubo's MFS (`/api/v0/files/*`) provides a path-addressed, mutable namespace
+//! backed by content-addressed IPFS objects — a natural fit for a key→blob store.
+//! Each object's etag is its IPFS CID (from `files/stat`), giving true
+//! content-addressing for the skip-redundant-download optimization.
+//!
+//! Requires a reachable Kubo HTTP API (`GITLAWB_IPFS_API`, e.g.
+//! `http://127.0.0.1:5001`). Objects written here are also retrievable by CID
+//! from the wider IPFS network once pinned/announced by the node.
+//!
+//! DEPLOYMENT RESTRICTION: MFS is the mutable namespace of ONE Kubo daemon —
+//! nothing here publishes a shared CID registry or IPNS mapping. Every
+//! gitlawb node in a network using this backend MUST point at the same Kubo
+//! instance; separate daemons produce disjoint namespaces where a push
+//! accepted on one node is invisible to the others. `storage::build` logs a
+//! startup warning to the same effect.

-/// Every explicit pre-git refusal must call `refuse_receive_pack_before_git` to

-/// 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.

-//! #26 Split PR 4 — `GITLAWB_ENFORCE_OWNER_PUSH` default is consistent across surfaces.
-//!
-//! Reviewer 2 (2026-08-28) closed PR #224 with a P2 finding: SECURITY.md and
-//! README.md both stated the default was `false`, while `Config::enforce_owner_push`
-//! declared `default_value_t = true` and the runtime, .env.example, and the env
-//! var table on the README all agreed with the code. Two operator-facing
-//! surfaces lied about the authorization policy. PR #330 flipped the code
-//! default and updated .env.example / README env table / docs/RUN-A-NODE.md,
-//! but missed these two prose mentions.
-//!
-//! This guard pins the documentation and example surfaces together. Each one
-//! is read off the working tree at test time, not a copy in the binary, so a
-//! revert of the doc edit turns it red:
-//!
-//! 1. `SECURITY.md` says the default is `true`.
-//! 2. `README.md` says the default is `true` in the known-limitations prose.
-//! 3. `README.md` says the default is `true` in the env-var table row.
-//! 4. `.env.example` sets `GITLAWB_ENFORCE_OWNER_PUSH=true`.
-//!
-//! The runtime declared default (`Config::enforce_owner_push`'s
-//! `default_value_t = true`) is protected by the
-//! `enforce_owner_push_is_declared_true_independent_of_the_environment`
-//! unit test in `config.rs`, which reads the parser directly and is
-//! env-independent. The two checks together cover the surfaces that
-//! produced the original doc-vs-code drift; this guard cannot reach into
-//! the binary crate's `Config` type (it is private to the bin target,
-//! which has no `lib.rs`) without a larger refactor, so the contract is
-//! stated as the four documentation/example surfaces above.
-//!
-//! The four are checked independently. A check that just verified "at least
-//! one surface says true" would pass while a stale SECURITY.md lied; a check
-//! that only verified the binary would not catch the doc drift that
-//! produced this finding in the first place.
