A real-socket, end-to-end security regression harness for gitlawb-node. It boots a real node on 127.0.0.1:0, drives trust-boundary DENY paths through a real reqwest client with real RFC-9421 signing, and asserts both the refusal status and that no withheld data leaks. It turns the per-PR real-node-verify step into executed tests, and covers ground tower::oneshot can't: the full production middleware stack over an actual socket, plus a systematic no-empty-200 (denial-as-success) assertion.
Why the crate split
gitlawb-node was binary-only, so an out-of-crate integration test could not reach build_router / AppState / Config. The first commit splits it into lib+bin: the module tree and boot logic move to src/lib.rs (exposing a minimal run() plus the boot surface), and src/main.rs becomes a thin #[tokio::main] shim. No behavior change, the 488-test node suite stays green and the production binary is unaffected. The harness itself lives behind a test-harness feature so its spawn surface never compiles into the release binary.
Coverage
Fourteen executed cases, one strong case per invariant plus a high-value owner-gate fan-out:
Denials are never rendered as empty/success: unsigned git-receive-pack rejected 401, and an anonymous /ipfs/{cid} read of a withheld blob denied 404 with no leak.
Mutations are owner-gated, not merely authenticated: a validly-signed non-owner is rejected 403 on set_visibility, plus protect/unprotect branch, webhook create/delete, and visibility removal. Each carries an owner-reachability check so a 403 from an earlier layer cannot masquerade as a pass.
Reads and replication gate on the requested path: a withheld blob read denied 404 with no leak, the same withhold over the content-addressed /ipfs surface, and the git-upload-pack replication path where the served pack must omit the withheld blob while keeping the sibling public one.
Every case is mutation-verified load-bearing: the specific gate was broken, the test observed to go red (the secret leaking, or the withheld object appearing in the pack), then reverted.
Notes for review
The upload-pack case drives the git-upload-pack POST directly (v0 stateless-RPC) instead of git clone, because a default git clone negotiates protocol v2 and hangs against the node's v0 server. That hang (rather than a clean error) may be worth a separate look if standard-client interop matters. The assertion is packfile-aware (git index-pack + verify-pack), not a raw byte scan, since a leaked OID would otherwise hide inside the zlib stream.
CI runs the harness explicitly with --features test-harness, since cargo test --workspace skips it by design.
Deliberately deferred: the lower-impact owner-gates and read surfaces (labels, PR comments, list_visibility, and similar) keep their existing source-level authz-table guard and gate-helper unit tests, where a full-stack case per endpoint adds near-zero marginal safety. Replica register/unregister were excluded because they are signer-self, not owner-gated.
Summary by CodeRabbit
Testing
Expanded automated checks for API access denials, information exposure in responses, and authorized access. These checks now run across configured toolchains.
Documentation
Clarified shutdown behavior: the server stops accepting connections, waits for in-progress requests up to the configured grace period, then exits. Connections still open at that point may close without a 503 response.
…can spawn a real node
Move the module tree and boot logic from main.rs into a new lib.rs crate
root exposing the boot surface (build_router, AppState, Config, migrations)
as pub; main.rs becomes a thin #[tokio::main] shim over run(). No behavior
change: both targets build and the full node suite (488 tests) stays green.
Prerequisite for the real-node deny harness (U1).
…-U4, U5a)
Add a feature-gated (test-harness) spawn surface (src/test_harness.rs) that
boots a real node on 127.0.0.1:0 over an ephemeral #[sqlx::test] pool through
the production axum::serve stack with connect-info, and an integration crate
(tests/deny_harness.rs) that drives deny paths with a real reqwest client:
- U2 signing client: wraps gitlawb_core::http_sig::sign_request for reqwest;
self-checks that a valid signature clears require_signature and a tampered
body is rejected (400 content_digest_mismatch).
- U3 spawn_node: real socket, p2p disabled, per-test DB, shutdown-on-drop.
- U4 assert_denied: 4xx AND body-no-leak AND not-empty-200 (INV-8); pure core
unit-tested for clean-403 / empty-200 / leaking-403 / wrong-status.
- U5a INV-8: unsigned git-receive-pack is denied 401 with no leak.
Widens the three cfg(test) test builders (Db/RepoStore::for_testing,
run_migrations) to also compile under the feature. No production behavior
change: prod build (no feature) excludes test_harness; node suite stays green
(488) and the 7 integration tests pass.
A validly signed non-owner PUT /visibility is rejected 403 by require_owner
(no x-ucan, so require_ucan_chain passes through to the gate); the owner's
signed PUT reaches the handler (reachability proof, guards against a 404/415
masquerading as a pass). Adds seed_repo/withhold_path seeding helpers to the
test harness. Mutation-verified load-bearing: with require_owner forced Ok the
non-owner PUT returns 201 and the INV-8 assertion flips the test RED.
Adds seed_bare_repo (shells git to build a real bare repo at the served path,
sha1 or sha256 object format) and two INV-2 deny cases over the real stack:
- U7: a public repo with a /secret/** withhold rule denies an anonymous blob
read of the withheld path (404) with no content/OID leak, while the sibling
public path is served (path-scoped, not blanket).
- U5b: the same withhold denies an anonymous /ipfs/{cid} read of the withheld
blob's content-addressed id (404, no leak), while the public blob's CID is
served. Completes U5 (INV-8) alongside U5a.
Both mutation-verified load-bearing: forcing visibility_check to allow leaks
the secret at 200 and the INV-8 assertion flips each test RED.
Drives the git-upload-pack POST directly (v0 stateless-RPC: want HEAD, flush,
done) via a bounded reqwest client rather than a vanilla `git clone` (which
negotiates protocol v2 and deadlocks against the node's v0 server, and would
otherwise wedge the suite). The served pack is indexed with git index-pack and
its objects listed with verify-pack -v: a packfile-aware assertion, since a raw
byte scan cannot see an OID inside the zlib-compressed stream.
A public repo with a /secret/** withhold rule must serve a pack that omits the
withheld blob's object while keeping the sibling public blob. Mutation-verified
load-bearing: forcing visibility_check to allow puts the withheld blob back in
the pack and flips the test RED.
Completes the harness (8 units, 11 integration tests). Prod build (no feature)
and the 488-test node suite stay green.
cargo test --workspace skips the harness because it lives behind the
test-harness feature (kept off the production binary). Add an explicit step
that runs it with the feature and the same Postgres service, so the INV-1/
INV-2/INV-8 trust-boundary regression cases execute on every PR instead of
only when run by hand.
Add unit tests for the two remaining check_denied branches: a non-4xx expected
status is rejected as a test bug, and an empty withheld token is skipped rather
than matching every body. Closes the last unexecuted branches in the deny
assertion.
Fan-out of U6 to the security-sensitive owner-gated mutations that had only the
source-level authz-table guard and no runtime deny test: protect_branch,
unprotect_branch, create_webhook, delete_webhook, remove_visibility. Each
rejects a validly-signed non-owner with 403 and lets the owner reach the
handler (not 403). Mutation-verified load-bearing on their shared root gate:
did_matches forced true opens all five (non-owner protect_branch returns 201)
and the test flips RED.
Replica register/unregister were intentionally excluded: they are signer-self
(you register your own node), not owner-gated, so there is no owner-deny to
assert.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
This change adds a feature-gated real-node test harness, a registry of authorization routes and generated denial probes, and shared request and response-checking support. The pull-request workflow runs the library and deny-harness tests with the configured Postgres service.
Adds a library target and feature-gated test target. Test database and repository helpers are available with test-harness; several types become public, and build stubs and test-only annotations are updated.
Real-node lifecycle and fixture seeding crates/gitlawb-node/src/test_harness.rs
Adds TestNode startup, shutdown, task teardown, and helpers that seed repositories, branches, pull requests, issues, visibility rules, pinned CIDs, and bare Git repositories.
Route registry and authorization probes crates/gitlawb-node/tests/support/routes.rs, crates/gitlawb-node/tests/support/probe.rs
Adds a route registry for authorization gates and fixture-driven probes. Probe generation pairs denials with authorized controls and checks for withheld private data.
Request helpers, denial checks, and CI crates/gitlawb-node/tests/support/mod.rs, crates/gitlawb-node/tests/support/signing.rs, crates/gitlawb-node/tests/support/assert.rs, .github/workflows/pr-checks.yml, .github/codeql/codeql-config.yml
Adds bounded HTTP clients, anonymous and signed request builders, and denial checks for status codes and withheld-token leakage. CI runs the library and deny-harness tests; CodeQL excludes test paths.

Warning
Review coverage is incomplete: 3 files could not be fully reviewed. Findings from completed review steps are included; see review info for details.
Only the clone test (line 344-347) builds its reqwest::Client with an explicit timeout, with a comment explaining why (avoiding a wedged suite). Every other test here (e.g. this one, and lines 67, 98, 123, 192, 249, 420) uses reqwest::Client::new() with no timeout. If the real node under test ever hangs on any of these paths, the test blocks until the 45-minute CI job timeout instead of failing fast with a clear cause.
Then swap each reqwest::Client::new() in this file for bounded_client().

Findings
[P1] Create identity keys atomically with owner-only permissions crates/gitlawb-node/src/lib.rs:1007
The new library retains the existing exists() → fs::write() flow. On Unix, fs::write creates the PEM using umask-derived permissions and only then changes it to 0600; a local process can read the node private key in that window. The separate existence check also lets concurrent node starts overwrite each other's generated identity. Create the file with create_new and mode 0600, then handle AlreadyExists by loading the winning key.
[P2] Enforce the configured HTTP shutdown grace period crates/gitlawb-node/src/lib.rs:539 with_graceful_shutdown begins draining when the signal fires but has no deadline; the computed grace is explicitly discarded at line 571. A long-lived request can therefore prevent termination until the orchestrator hard-kills the process, defeating GITLAWB_SHUTDOWN_GRACE_SECS and risking interrupted cleanup. Bound the drain with that duration and force completion once it expires.
- Create the node identity key atomically with create_new + mode 0600, closing
the umask-derived 0644 disclosure window and the exists()->write overwrite
race; on AlreadyExists load the winner's key (bounded retry so a loser can't
read a half-written PEM) and tighten looser perms on load.
- Enforce the configured shutdown grace: bound the axum drain by grace measured
from the signal (extracted as drive_serve_with_grace), abandoning in-flight
requests once it expires instead of waiting indefinitely. Removes the
discarded grace value.
- Route deny-harness reqwest clients through a shared bounded_client (30s
timeout) so a wedged node path fails fast instead of hanging to the CI limit.

P1 (identity key). Created atomically with OpenOptions::create_new(true).mode(0o600) and written through that handle, so there is no umask-derived 0644 window. A lost race hits AlreadyExists and loads the winner's key instead of overwriting, with a short bounded retry so it can't read a half-written PEM; loading an existing key also tightens loose perms to 0600.
P2 (shutdown grace). The drain is now bounded by the configured grace, measured from the signal rather than server start (extracted as drive_serve_with_grace) and forced to complete once it expires. The discarded grace is gone and the misleading comment corrected.
Unit tests cover 0600-on-create, tighten-on-load, 8-thread concurrent-start convergence, and the grace abandon / normal-drain / signal-gated paths.
Also took CodeRabbit's nitpick: the deny-harness clients now go through a shared 30s bounded_client so a wedged route fails fast instead of hanging to the CI timeout.

Findings
[P1] Remove a failed first-write identity file crates/gitlawb-node/src/lib.rs:1123
The new create_new(true) path fixes the original permission window, but if the PEM write itself fails after the file has been created, the just-created key path is left behind as an empty or partial PEM. Every later start then takes the key_path.exists() branch, retries parsing that same bad file in load_racing, and exits with invalid PEM key instead of generating a fresh identity. A transient ENOSPC/EIO/quota failure during first boot can therefore permanently wedge the node until an operator manually deletes the file. Please remove the newly-created file on write_all failure in both the Unix and non-Unix branches before returning the error.
[P2] Do not ignore failed key permission tightening crates/gitlawb-node/src/lib.rs:1059
The load path now advertises that loose existing identity keys are tightened to 0600, but the set_permissions result is discarded. If the file is readable but chmod fails, for example on a read-only mount or an ownership/ACL mismatch, the node still reads and uses a world/group-readable private key while logging a normal "loaded existing identity" path. That leaves the exact key exposure this follow-up is trying to close. Please surface the chmod failure or otherwise verify the final mode before continuing with the key.

the just-created file on write failure, and wire it into both the unix and non-unix

Remove a failed first-write (F1). Extracted write_key_or_cleanup, which removes the just-created file when write_all fails, and wired it into both the Unix and non-Unix create branches. A transient ENOSPC/EIO on first boot now leaves no file, so the next start regenerates instead of re-parsing an empty/partial PEM forever. Covered by failed_write_removes_the_partial_key_file (an injected write error removes the file; RED with the remove_file disabled), and I confirmed the non-Unix branch type-checks by compiling it via a temporary cfg swap.
Do not ignore a failed permission tighten (F2). The load path now propagates the set_permissions error and then calls ensure_key_mode_0600, which fails closed if the key is not 0600 after the attempt — so a chmod that failed or silently no-opd (read-only mount, ACL mismatch) is refused rather than read and used exposed. Covered by loose_key_mode_is_rejected_not_used (a 0644 key is rejected, a 0600 key accepted; RED with the check disabled). existing_key_is_loaded_and_tightened still passes (a loose key on a writable mount is tightened and loaded).
One behavior note on F2: a loose key that genuinely cannot be tightened is now rejected rather than used, which narrows the original "never reject a loose key" leniency — but only in the exposed-and-unfixable case, which is the exposure this follow-up closes. The real ENOSPC/chmod-fail I/O triggers are not driven end to end (no portable fault injection), but the error handling is proven at the helper level and the wiring is a one-line pass-through of the write/chmod result into it.
RED->GREEN for each; no other production behavior changes.

Findings
[P2] Do not fail concurrent startup after an arbitrary 100 ms key-write window crates/gitlawb-node/src/lib.rs:1123 create_new exposes the final key path before the winner has completed write_all, and every other process that sees that inode gives up after 50 2-ms retries. On a slow or temporarily stalled filesystem, a winner can legitimately take longer than that interval, so all losing node starts return invalid PEM key even though the winning write later succeeds. This reintroduces an availability failure for the concurrent-start case the new code is intended to make safe. Keep retrying until a meaningful startup deadline, or publish a fully written temporary key atomically so readers never observe a partial final file.
The create path did create_new(final)+write_all, so the final path appeared as
an empty inode before the PEM was flushed, and a losing/fast-path start only
retried ~100ms (50x2ms). On a slow or stalled filesystem the winner's write can
exceed that window, so every other start failed boot with 'invalid PEM key'
(#194). Publish atomically instead: write the full PEM to a sibling temp, then
hard_link it into place. hard_link is atomic and fails if the target exists, so
the final path only ever appears COMPLETE (no partial-read window), a lost race
never clobbers the winner, and a crashed writer leaves only a temp rather than a
partial final that would wedge later starts. load_racing_key now polls on a
wall-clock KEY_RACE_DEADLINE (5s) instead of a fixed 100ms count. Hoisted
load_existing_key/load_racing_key to module level for testability.
Adversarial RED->GREEN: a 250ms-slow winner is waited out (RED at the old 100ms);
a reader watching the final never sees a partial file (RED with create_new+write);
a losing publish does not clobber the winner; 500 tests pass.

The finding is right. The create path did create_new(final)+write_all, so the final path appears as an empty inode before the PEM is flushed, and load_racing only retried 50 × 2ms ≈ 100ms — a slow/stalled-FS winner can exceed that, and every other start then fails boot with invalid PEM key.
I took option (b), keeping the single-winner guarantee: write the full PEM to a sibling temp, then hard_link it into place. hard_link is atomic and fails if the target exists, which gives three things at once — the final path only ever appears complete (no partial-read window), a lost race never clobbers the winner, and a crashed writer leaves only the temp rather than a partial final that would wedge later boots. load_racing_key now polls on a wall-clock deadline (5s) instead of a fixed 100ms count. I hoisted load_existing_key/load_racing_key to module level so the deadline is directly testable.
Vetted both ways:
A 250ms-slow winner is now waited out — RED when I reverted the deadline to 100ms.
A reader watching the final path never observes an empty/partial file — RED when I reverted the publish to create_new(final)+write.
A losing publish does not clobber the winner (and temps are cleaned up); the existing convergence test stays green.
Full suite 500 pass; fmt and clippy -D warnings clean.
Two deliberate tradeoffs worth flagging:
The atomic publish uses hard_link, so it now requires a filesystem that supports hard links. Every normal node key location (ext4/xfs/overlay/tmpfs) does; a hardlink-less mount would fail boot loudly with a clear error rather than silently. Happy to add a create_new+write fallback for that case if you'd prefer universal-FS support over failing loud.
A genuinely corrupt existing key now blocks boot up to the 5s deadline before erroring (a valid key still parses on the first attempt, no delay).
The reason will be displayed to describe this comment to others. Learn more.
I found issues that need to be addressed before this is ready.
This review is scoped to what head 988e8ea actually changes and what blocks merge today. The deny harness itself looks structurally sound on head (parent-dir reload mask and enforce_owner_push socket coverage landed in the latest commit). The items below are the remaining gaps — not a request to reopen boot-path design or expand harness registry scope.
Merge readiness
[P1] Green the required CodeQL check (fixture false positive, not a production leak) crates/gitlawb-node/tests/support/assert.rs:115-118 .github/codeql/codeql-config.yml
What is failing: On head 988e8ea, the aggregate CodeQL required check is FAIL (mergeStateStatus: BLOCKED). GitHub Advanced Security reports one open alert on this PR:
Rule
Location
Severity
rust/cleartext-logging
assert.rs:118 (panic!("{redacted}"))
warning
The earlier rust/cleartext-transmission alert on deny_harness.rs is cleared on head (URL built via secret_path variable instead of embedding the CID in the .get() expression CodeQL traced).
This is not a production security defect.assert_denied runs only in the deny harness. It panics when a deny probe fails — i.e., when the test has already detected a problem. At runtime, redact_withheld strips withheld OIDs/CIDs from the message before panic!. No production path logs secrets; no loopback client receives them from this helper on the success path.
Root cause: CodeQL's taint analysis follows withheld tokens from check_denied_with_headers into the reason string (the error path embeds the token in withheld token {token:?} leaked…), then through redact_withheld, and still flags the panic! sink. Static analysis does not treat redact_withheld as a sanitizer. Branch mitigations did not clear the head run:
paths-ignore: **/tests/** — does exclude tests/support/assert.rs, but PR diff scanning still raised the alert on the changed file; do not assume paths-ignore alone greens PR checks without a verified push.
paths-ignore: **/test_support/** — does not match anything in this repo (tests/support/ is the actual layout; in-crate src/test_support.rs is a file, not a directory).
Inline codeql[...] comments — did not clear the head alert on the panic line.
How to fix (pick one path, verify on push before re-requesting review):
Restructure the failure witness so taint never reaches the sink (preferred if you want zero Security-tab noise):
Build the panic message from fixed strings only, e.g. panic!("deny assertion failed: status/body/header leak check").
Log redacted detail via a separate channel CodeQL does not trace to a log sink, or assert with assert!(false, "…") using only static text and pass redacted detail as separate arguments that do not embed raw tokens in the format string.
Keep redact_withheld unit tests — they still validate the redaction helper even if assert_denied no longer panics with interpolated secrets.
Security-tab dismissal (acceptable for fixture-only alerts if the team uses dismissals for test harnesses):
Dismiss rust/cleartext-logging on assert.rs:118 as false positive ("loopback deny-harness test failure witness; tokens redacted before panic; no production path").
Link the dismissal URLs in a PR comment. Dismissal greens the aggregate check only after GitHub processes it — confirm on the finished run.
Working suppression on the exact flagged line — only if you confirm on a finished CodeQL run that the suppression is honored (prior inline attempts on this branch did not).
Do not: disable CodeQL, add broad paths-ignore for src/, or weaken check_denied leak detection on the success path.
Findings
[P2] Restore gossip readiness tests lost in the lib+bin move (coverage regression, not harness logic) crates/gitlawb-node/src/lib.rs — gossip_ssrf_tests (~3640–3815)
merge-base reference: crates/gitlawb-node/src/main.rs (pre-split)
What broke: The lib+bin extraction moved ping_peer_readiness_with_timeout into lib.rsunchanged (function body is byte-identical to merge-base). The unit tests beside it were not fully carried over: merge-base had 7ping_peer_* tests; head has 3 renamed ping_peer_health_* tests. Production gossip behavior is the same; CI guardrails shrank.
Root cause: Mechanical main.rs → lib.rs move copied production code but dropped part of the gossip_ssrf_tests module. Commit 692b894 ("restore lib/bin boot regressions dropped in the deny-harness extraction") fixed several boot-path gaps but did not restore this gossip suite. This is collateral damage from the crate split, not a defect in the deny harness routes, registry, or spawn_node wiring.
What head still covers:
Retained test
What it guards
ping_peer_health_does_not_follow_redirect
Legacy /health 302 must not be followed (SSRF) when /ready is 404
ping_peer_health_reports_success_on_200
Legacy /health 200 counts as healthy when /ready is 404
What is missing and why it matters (distinct from retained tests):
Dropped test (merge-base name)
Gap if not restored
ping_peer_readiness_reports_success_on_200
/ready 200 happy path never exercised — retained tests only hit /ready 404 then /health
ping_peer_readiness_ignores_liveness_only_health
Most important:/ready 503 + /health 200 must not mark peer ready. Current code handles this at 1260:1266:crates/gitlawb-node/src/lib.rs (non-404, non-success → false without fallback), but nothing in CI would catch a refactor that reintroduced /health fallback on 503
Serial /ready + /health probes must share one timeout envelope — subtle regression class
ping_peer_readiness_falls_back_for_legacy_peer
Explicit expect-count contract for 404→200 sequence (mostly overlapping with retained health test, lowest priority)
ping_peer_readiness_legacy_fallback_does_not_follow_redirect overlaps heavily with the retained redirect test; restoring it is optional.
Smallest fix: Copy the four merge-base tests (or the top three rows excluding the optional overlap) into gossip_ssrf_tests in lib.rs, using ping_peer_readiness_with_timeout where the shared-deadline test needs it. No production code change required unless a test fails.
Scope boundary: This is lib-move test parity, not deny-harness expansion. Do not fold this into registry rows, GraphQL coverage, or further boot-path changes. If you prefer to defer, open a tracked follow-up and note it in the PR comment — but merging as-is reducesmain's federation-readiness coverage for unchanged code.
Author guidance (close-out without more review drift)
These are not additional findings — they are how to land this PR without another drip round:
Treat CodeQL as verify-on-push. Push the fix or dismissal, wait for the CodeQL run to finish, link the green run (or dismissal URLs) in a PR comment, then request re-review. Do not stack another untested suppression commit.
Freeze production boot changes for the merge push. Head already includes identity recovery, shutdown grace, and gossip hysteresis restoration. Further lib.rs boot edits in this branch re-open security review unrelated to the harness deliverable. Follow-ups belong in separate PRs.
Update the PR body once, honestly. Replace "No behavior change" with a short scope contract: what the harness covers (REST deny paths, INV-1/2/8 cases listed), what it excludes (GraphQL #219, iCaptcha enforce mode, global listings), and that the lib+bin split also carries boot hardening already on head. A signed boot-invariant checklist (validate, lock pool, build_http_client, gossip hysteresis+abort, drive_serve_with_grace, parent-dir 0o077) lets reviewers treat further boot tweaks as out of scope.
Do not expand harness scope in this PR to chase lower-impact owner gates, GraphQL, or encrypted-blob surfaces — those are documented deferrals with existing unit-test guards. The registry/completeness machinery is already large; more rows invite "what about X?" rounds without proportional safety gain.
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).
Both findings from the 2026-09-08 review are closed on 4c42d78.
CodeQL cleartext-logging (P1): replaced the interpolated panic!("{redacted}")
with a fixed string so no tainted data reaches the sink. CodeQL's taint analysis
traced withheld tokens through redact_withheld without recognizing it as a
sanitizer; a fixed message sidesteps that entirely. redact_withheld is still
called (keeping it live) and its unit tests still pass. This is a test-only
fixture: no production path calls assert_denied. Will verify the CodeQL run
greens on push.
Gossip readiness tests (P2): restored the 4 tests dropped in the lib+bin split: ping_peer_readiness_reports_success_on_200, ping_peer_readiness_ignores_liveness_only_health, ping_peer_readiness_falls_back_for_legacy_peer, and ping_peer_readiness_legacy_fallback_shares_deadline. No production code
change; function signatures are unchanged. 9/9 gossip tests pass, 53/53 deny
harness tests pass, fmt and clippy clean.
Per your close-out guidance: no boot-path changes, no harness scope expansion,
no further production edits in this branch.
The reason will be displayed to describe this comment to others. Learn more.
The deny harness itself is the best testing artifact I have seen on this repo: real node on an ephemeral port, real RFC-9421 signing, the ~52-row registry expanded into hostile plus positive twins with hard count assertions so a dropped probe fails the suite, byte-exact no-leak body and header scans, packfile-aware replication checks, and a source-scrape completeness fence with a closed NotDrivenReason enum. My blocker is disclosure: the PR carries roughly 1,800 lines of new production code - the atomic identity-key publication, quarantine, recovery-claims, adoption, and stale-marker sweep subsystem in lib.rs, plus restructuring of run()'s degraded lifecycle - while the body claims No behavior change for a test(node) split. Crash-recovery semantics for the node's own identity key deserve their own review; please split those commits out or rewrite the body to own them. Named residual: the 401-only signed writes (profile, sync/trigger, announce, bounty claim) have no registry rows yet.
…arness
- lib.rs regenerated from current main.rs so the extraction reflects
72 commits of drift; new modules added since July stay crate-private,
the harness-reachable ones are pub
- main.rs trimmed back to the thin run() shim
- test_harness.rs updated for drift: TaskCursorKey into build_schema and
AppState, plus the webhook_secret_key, close_issue, federated, and
task_read limiter fields main added
- tempfile moved to an optional dep under the test-harness feature
(dev-deps are invisible to lib modules)
- four types made pub where pub items now expose them through the lib
surface; the deduplicated pool() keeps its test-only cfg
Main's quarantine read pre-checks and task visibility layering landed
after the registry froze, so the merged table needed three classes of
refresh:
- scan hygiene: mask string/comment contents and strip cfg(test) mods
before the marker scans, so fixture text (the resolver_body helper)
cannot fake a decl boundary or inherit markers
- registry refresh: allowlist the read-gating mutations that gained
authorize_repo_read (merge_pr, visibility/protect/webhook/label/
bounty/close/replica writes, git_receive_pack), drop the task_claimable
helper and create_task's dedicated-test-driven conditional owner gate,
and class list_visibility (owner-driven GET) and list_anchors
(query-scoped read) explicitly
- sweep substrate: scope the visibility twins to /swept-scope so
set_visibility cannot 404 later strangers on the shared repo, and seed
completable/failable tasks on the public repo so strangers reach the
assignee 403 through get_visible_task
Put safe diagnostics in the panic message and remove the dead redaction call.
The fixed string hides which check failed: wrong status, denial rendered as success, body leak, or header leak. In CI, a sweep failure then reads only "status/body/header leak check". The let _ = redact_withheld(...) line does nothing.
status and expected are integers and carry no withheld data. Add them to the message. Also add a fixed category string chosen from the failure kind. This keeps CodeQL's taint path free of withheld tokens.
Proposed change
- let _ = redact_withheld(&reason, withheld);- panic!("deny assertion failed: status/body/header leak check");+ let kind = if reason.contains("leaked in denial headers") {+ "header leak"+ } else if reason.contains("leaked in denial body") {+ "body leak"+ } else if reason.contains("rendered as success") {+ "denial rendered as success"+ } else {+ "status mismatch"+ };+ panic!("deny assertion failed ({kind}): got {status}, expected {expected}");

requests for a bounded period or abandons them at expiry.
Review comments at @crates/gitlawb-node/src/git/repo_store.rs:
- Around line 88-95: Retain a handle to the lock pool created by `for_testing`

- Around line 88-95: Update RepoStore::for_testing so callers that supply an
explicitly configured lock pool can pass that same pool into the store, keeping
exhaustion, waiter, and deadline tests aligned with the pool they inspect.
Preserve the derived pool for callers that require its after_release hook, using
RepoStore::new or a separate test constructor where appropriate.

The merge reconstruction derived an 8-connection lock pool inside
for_testing, so callers passing a pool observed nothing checked out.
Main's contract is that the argument IS the lock pool, which the
exhaustion, deadline, backend-reuse, and waiter-isolation tests observe
directly. Route through Self::new like for_testing_with_tigris so the
cfg(test) fields stay gated.
No — merge-base main.rs contained purge strings; same gate passed
Yes — regression from lib/bin split; companion update to inv22_gates.rs (file unchanged in diff but caused by this PR)
CI cargo test red
Yes — exit 101 on inv22_gates
No — follows split
Yes
Deny harness step skipped
Yes — step after failing cargo test
N/A (step is new)
Yes — PR-activated until P0 fixed
Not in this draft (withheld after drift check): harness GITLAWB_* env parity (same as pre-existing test_support), repos_dir desync without a failing deny route today, GraphQL outside harness (#219 deferral), full run() clone in build_state, CodeQL tests/** ignore, expanded pub lib surface for the split. Those are not asserted as author-blocking defects on this head.
Merge readiness
🔴 P0 — Required CI cargo test jobs fail on this head
📍 Where: GitHub Actions test (beta) and test (stable) on run 43036751368.
💥 What fails: The workspace cargo test step exits 101 before later steps run.
🔎 Root cause: The lib/bin split moved queue-lifecycle purge boot wiring from main.rs to lib.rs without updating the INV-26 source gate that still reads main.rs.
📜 Stated contract:
Load-bearing gate inv26_step4_queue_lifecycle_purge_is_wired requires the boot module to contain spawn_queue_lifecycle_sweep and purge_request_queue (inv22_gates.rs; today it still names main.rs in assertions).
🏷️ Attribution: PR-introduced — at merge-base those substrings lived in main.rs (~L654, ~L929); head main.rs is 7 lines and wiring is in lib.rs (~L660, ~L935–953).
📌 In this PR:
crates/gitlawb-node/src/lib.rs — purge spawn wiring in run()
crates/gitlawb-node/src/main.rs — shim only
CI — red until gate file target matches boot
🔒 Unchanged on main: Purge must remain wired at boot; do not delete or relocate purge behavior beyond the lib split already done.
🔧 Required correction: Align the INV-26 gate with lib.rs (finding below); re-run CI through the deny-harness step.
🛠️ Author fix: Land the gate fix in this PR branch so cargo test and the explicit deny-harness step both go green on CI.
🚫 Out of scope: Restoring a fat main.rs, changing purge semantics, or expanding into harness/production parity work.
🟠 P1 — Real-node deny harness did not run in CI on this head
📍 Where:.github/workflows/pr-checks.yml — cargo test (real-node deny harness) immediately after workspace cargo test.
💥 What fails: On run 43036751368 the socket INV suite did not execute because the prior step failed.
🔎 Root cause: Standard step ordering; not a harness bug by itself.
📜 Stated contract:
This PR adds an explicit step so INV-1/2/8 deny regressions run with --features test-harness when the node crate is in scope (workflow comment + PR body).
🏷️ Attribution: PR-activated — consequence of P0, not a separate pre-existing CI flake.
📌 In this PR:
.github/workflows/pr-checks.yml — new step (in diff)
🔧 Required correction: After P0 fix, verify CI logs show cargo test … --test deny_harness completing.
🛠️ Author fix: No workflow change required unless you want if: always() on the harness step; primary fix is green workspace tests.
🚫 Out of scope: Requiring GraphQL socket coverage or env-scrubbing in this round unless you choose follow-up.
Findings
🟠 P1 — INV-26 queue purge gate still source-scans main.rs after boot move to lib.rs
thread panicked: main.rs must spawn the periodic queue-lifecycle purge
cargo test -p gitlawb-node --test inv22_gates inv26_step4_queue_lifecycle_purge_is_wired — fail on head. CI job 130577546400 — same.
🔎 Root cause: The gate’s file pointer is stale: it still src("main.rs") while production boot and purge spawn live in lib.rs after this PR’s split.
📜 Stated contract:
inv26_step4_queue_lifecycle_purge_is_wired asserts main.rs contains spawn_queue_lifecycle_sweep and purge_request_queue (inv22_gates.rs L732–739). The invariant under test is “purge lifecycle wired at boot”; the cited filename is what the gate enforces today.
🏷️ Attribution: PR-introduced — inv22_gates.rs is unchanged in the three-dot diff, but the split newly breaks a gate that passed at merge-base.
📌 In this PR:
crates/gitlawb-node/src/lib.rs — strings present (in diff)
crates/gitlawb-node/src/main.rs — strings absent (in diff)
crates/gitlawb-node/tests/inv22_gates.rs — must update to scan boot module (companion fix for split; not scope drift)
🔒 Unchanged on main:durable_outbox::purge_request_queue behavior; other inv22_gates scans unchanged unless they still say main.rs for boot-only symbols.
🔧 Required correction: Change src("main.rs") to src("lib.rs") (or one shared helper), update the module doc (“wired in main.rs” → lib.rs), and update panic messages to match the scanned file. Keep checking the same two substrings.
🛠️ Author fix: One commit touching inv22_gates.rs only for this invariant—doc comment + src(...) + both assertion strings together; do not duplicate boot into main.rs.
🚫 Out of scope: Harness env pinning, repos_dir alignment, GraphQL deny coverage, or reverting the library crate layout.
Notes (non-blocking)
Earlier review rounds’ harness teardown items (join_or_abort, pool.close on graceful shutdown) appear addressed on this head.
On this head: build --release, fmt+clippy, MSRV, Docker smoke, CodeQL — pass.
Intentionally not filed: items listed in the attribution table above; re-open only with a quoted contract and a failing path on the current deny registry or CI.
- config.rs: GITLAWB_SHUTDOWN_GRACE_SECS documented an enforced drain
bound that production never applies; the value is only logged and axum
drains in-flight requests unbounded. Say so.
- test_harness.rs: join_or_abort unwound a serve-task panic before
pool.close() ran, leaking the test database on exactly the path where
teardown matters. Carry the payload as ServeTeardown::Panicked and
resume unwinding only after the pool and repos dir are released.
- probe.rs: the cert-push workdir was keyed on pid+server_main_tip, which
two parallel fixtures seeding within one second share; one fixture's
cleanup could delete another's in-progress tree. Use a tempfile
TempDir, which is unique and also cleans up on the panic path.
The queue-lifecycle purge boot wiring moved from main.rs to lib.rs in the
crate split, but the source gate still scanned main.rs, so
inv26_step4_queue_lifecycle_purge_is_wired panicked in CI while the
purge itself stayed correctly wired. Scan lib.rs and update the doc and
assertion strings; the purge contract is unchanged.
The queue-lifecycle gate fix is on a7900ea: inv26_step4_queue_lifecycle_purge_is_wired now scans lib.rs for spawn_queue_lifecycle_sweep and purge_request_queue after the lib/bin split moved boot wiring there. cargo test -p gitlawb-node --test inv22_gates passes 12/12 locally, and the pre-push gate ran the deny_harness suite green.
Three more fixes landed on 01d81a7 against the coderabbit findings: the shutdown_grace_secs doc now states the value is logged but not enforced, a serve-task panic is carried past pool.close() and repos-dir removal as ServeTeardown::Panicked before resuming, and the cert-push workdir uses a tempfile TempDir so parallel fixtures cannot collide and panic paths still clean up.
The reason will be displayed to describe this comment to others. Learn more.
Merge readiness
🔵 P3 — Rebase onto current main before merge-queue
📍 Where: Branch feat/real-node-deny-harness vs live main (7ae4707).
💥 What fails: The branch merge-base is still 4fc041a; main has two newer commits (docs: PROTOCOL.md, gl: --icaptcha-proof) that are not on this head. This diff does not touch those files, so conflict risk looks low, but merging without rebase leaves the branch technically stale.
🔎 Root cause: Long-lived feature branch; last merge from origin/main predates those two commits.
📜 Stated contract:
Project practice on this repo treats stale-base drift as a merge-queue hygiene item when main has moved since the last integration.
🏷️ Attribution: Target-branch drift — not introduced by the harness diff itself.
📌 In this PR:
No file overlap with the two missing commits observed in a three-dot check.
🔧 Required correction: Rebase or merge current main, then let required checks run on the updated head.
🛠️ Author fix: One integration commit with main; no harness logic change expected.
🚫 Out of scope: Absorbing unrelated gl / docs work beyond conflict resolution.
🔵 P3 — Wait for the stable cargo test job on the latest head
📍 Where: GitHub Actions run for commit a7900ea / follow-up pushes.
💥 What fails: At review time, test (stable) and test (beta) were still pending on the run tied to the post-fix head, while fmt/clippy, MSRV, release build, and Docker smoke were already green.
🔎 Root cause: Normal CI queue latency after the INV-26 and harness fix commits.
📜 Stated contract:
Required PR checks must complete on the merge head before merge.
🏷️ Attribution: Operational — not a code defect on the diff.
📌 In this PR:
Local verification on this head: inv22_gates 12/12 and deny_harness 53/53 with Postgres.
🔧 Required correction: Confirm the stable job log shows workspace cargo test and the explicit deny_harness step green on the merge head.
🛠️ Author fix: None if CI is already green by merge time; otherwise push only if a real failure appears in logs.
🚫 Out of scope: Windows deny harness (explicitly out of CI scope today).
🟢 Thanks for the contribution. I do not see any actionable code defects on this head.
The lib/bin split regression (INV-26 gate scanning main.rs), harness teardown ordering, cert-push fixture isolation, and shutdown-grace operator doc all match what you described on a7900ea / 01d81a7. I rechecked them locally against the prior request-changes review. Harness-vs-production gaps called out earlier (full daemon workers, separate lock pool in spawn, GraphQL socket coverage) remain documented deferrals, not regressions on the exercised INV-1/2/8 paths.
Verdict: Comment — no actionable code findings on this head; required CI still has a red workspace-test job at review time.
Merge readiness
🟡 P2 — test (beta) failed; deny-harness step did not run
📍 Where: GitHub Actions run 43090562710, job test (beta).
💥 What fails: Workspace cargo test exited 101 with one failure:
test test_support::helper_tests::fake_git_with_refs_emits_the_column_shape ... FAILED
panicked at crates/gitlawb-node/src/test_support.rs:317:14:
run script: Os { code: 26, kind: ExecutableFileBusy, message: "Text file busy" }
The log shows 1939 passed; 1 failed. The added step cargo test (real-node deny harness) did not appear in the job log (it runs only after the workspace test step succeeds).
🔎 Root cause:ETXTBSY when executing a script file immediately after write+chmod — classic intermittent Linux behavior. The failing test body is unchanged in this PR’s three-dot diff (only unrelated #[allow(dead_code)] annotations elsewhere in test_support.rs).
📜 Stated contract:
PR Checks runs workspace cargo test before the explicit deny-harness step (.github/workflows/pr-checks.yml).
🏷️ Attribution: Unchanged pre-existing test at merge-base; PR-activated only in the sense that a red workspace job blocks the new trust-boundary suite on this pipeline ordering.
📌 In this PR:
.github/workflows/pr-checks.yml — deny harness step is downstream of workspace test (in diff)
🔒 Unchanged on main:fake_git_with_refs_emits_the_column_shape implementation.
🔧 Required correction: Re-run CI (flake may clear). If test (beta) and test (stable) stay red on the same test, harden test_support.rs:314–317 (e.g. sync/close before Command::new(&script_path)) in a focused follow-up — not required to complete the deny-harness feature itself.
🛠️ Author fix: Confirm green test (beta) / test (stable) on this head and that logs show cargo test … --test deny_harness completing. No change needed if the next CI run is green.
🚫 Out of scope: Harness/production boot parity, GraphQL deny coverage (#219), or query-scoped read routes excluded by design.
🔵 P3 — Prior review item verified fixed on this head
💥 What fails: Nothing on 91a4f5dc (jatmn review on cef22c8 reported main.rs scan failure).
🔎 Root cause: Commit a7900ea retargets the gate to lib.rs after the lib/bin split.
📜 Stated contract:
Gate requires boot module to contain spawn_queue_lifecycle_sweep and purge_request_queue.
🏷️ Attribution: PR-introduced regression on older head; fixed on current head.
📌 In this PR:
tests/inv22_gates.rs — scans lib.rs (companion to split)
🔧 Required correction: None on this head (local cargo test -p gitlawb-node --test inv22_gates — 12/12 pass).
Findings
🟢 Thanks for the contribution. I do not see any actionable code defects on head 91a4f5dc from this campaign.
(Local validation: inv22_gates 12/12 pass; deny harness completeness guards 17/17 pass with --features test-harness; socket #[sqlx::test] cases were not run locally due to Postgres credentials mismatch — rely on CI once workspace cargo test is green.)

What
A real-socket, end-to-end security regression harness for gitlawb-node. It boots a real node on
127.0.0.1:0, drives trust-boundary DENY paths through a real reqwest client with real RFC-9421 signing, and asserts both the refusal status and that no withheld data leaks. It turns the per-PR real-node-verify step into executed tests, and covers groundtower::oneshotcan't: the full production middleware stack over an actual socket, plus a systematic no-empty-200 (denial-as-success) assertion.Why the crate split
gitlawb-node was binary-only, so an out-of-crate integration test could not reach
build_router/AppState/Config. The first commit splits it into lib+bin: the module tree and boot logic move tosrc/lib.rs(exposing a minimalrun()plus the boot surface), andsrc/main.rsbecomes a thin#[tokio::main]shim. No behavior change, the 488-test node suite stays green and the production binary is unaffected. The harness itself lives behind atest-harnessfeature so its spawn surface never compiles into the release binary.Coverage
Fourteen executed cases, one strong case per invariant plus a high-value owner-gate fan-out:
/ipfs/{cid}read of a withheld blob denied 404 with no leak./ipfssurface, and the git-upload-pack replication path where the served pack must omit the withheld blob while keeping the sibling public one.Every case is mutation-verified load-bearing: the specific gate was broken, the test observed to go red (the secret leaking, or the withheld object appearing in the pack), then reverted.
Notes for review
git-upload-packPOST directly (v0 stateless-RPC) instead ofgit clone, because a defaultgit clonenegotiates protocol v2 and hangs against the node's v0 server. That hang (rather than a clean error) may be worth a separate look if standard-client interop matters. The assertion is packfile-aware (git index-pack+verify-pack), not a raw byte scan, since a leaked OID would otherwise hide inside the zlib stream.--features test-harness, sincecargo test --workspaceskips it by design.Summary by CodeRabbit
