test(node): clear CodeQL alert and restore gossip readiness tests

Two findings from the 2026-09-08 review on head 988e8ea:

1. CodeQL rust/cleartext-logging on assert.rs:118. The panic sink
   interpolated redact_withheld(&reason, withheld), but CodeQL's taint
   analysis traces withheld tokens through redact_withheld without
   recognizing it as a sanitizer. Replace the interpolated panic with a
   fixed string so no tainted data reaches the sink. redact_withheld is
   still called (keeping it live) and its unit tests still pass; only the
   panic message changes. This is a test-only fixture false positive: no
   production path logs secrets.

2. Four gossip readiness tests dropped in the lib+bin split. Merge-base
   main.rs had 7 ping_peer_* tests; head had 3 renamed ping_peer_health_*
   tests. Restore the 4 missing: the /ready 200 direct happy path, the
   /ready 503 + /health 200 must-not-be-ready case, the legacy fallback
   with explicit expect-count, and the shared-deadline probe. No
   production code change; the function signatures are unchanged.

Verified: cargo fmt --check, cargo clippy -- -D warnings, 9 gossip
tests pass, 53 deny_harness tests pass (including assert unit tests).

 - 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.
 - Read visibility is not a blanket data-classification boundary: task, 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.
 - Peer writes are signed by upgraded nodes, but strict signed-peer enforcement is opt-in during rolling upgrades.
-- GraphQL mutations require a signed identity (a verified signer bound to the acting DID), are limited to the agent-task queue, and are covered by a CI completeness fence that requires signer acquisition and actor binding on every registered mutation; repo writes are not exposed over GraphQL and remain REST-only.

 `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.

-  suffix, or drop it and let identify supply the current one. Addresses without
-  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.

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.

-//! 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.

-//! #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.
