beardthelionandt cd67718f49 fix(node,git): bound a hung served git with a total-duration timeout (#62) (#165)
* feat(node,git): bound a hung served git with a total-duration timeout (#62)

Part 1 of #62. A served git upload-pack/receive-pack that neither finishes
nor disconnects parks forever, pinning a git PID (and, for receive-pack,
holding the write lock); on a public repo an anonymous caller can trigger
it. No tower TimeoutLayer exists and axum imposes no default.

Wrap the child interaction in tokio::time::timeout, bounded by a new
GITLAWB_GIT_SERVICE_TIMEOUT_SECS knob (default 600, must be positive).
Drain stdout/stderr concurrently with the stdin write so a large body
can't deadlock. On expiry run_git_service returns a typed GitServiceTimeout
and reaps the WHOLE process group before returning (SIGTERM so git clears
its .git/*.lock, wait for the leader and its grandchildren like index-pack
to exit, escalate to SIGKILL past a grace, hard-capped), so a caller
releasing the receive-pack write lock can't race a still-live git on the
same repo.

The handlers map GitServiceTimeout to a distinct 504 (not the generic 500
git error, and clear of the read-gate 404 / auth 401 the client keys
retries on) via a pure, unit-testable classifier rather than matching the
anyhow string. Surface git's own non-zero exit (its stderr) before a
stdin-write EPIPE so a malformed body is classified 400, not 500.

Out of scope, deferred in #62: the info/refs advertisement and the
withheld-blob path (spawn_blocking, which tokio timeout cannot cancel);
both remain unbounded (noted in the config knob's docs).

Tests: the timeout fires and tears the group down; it reaps the whole
group before returning (RED if the reap is leader-only); the wrap is
load-bearing (RED via an outer bound, not a hang); the error must be the
typed timeout; the 504 mapping and classifier are unit-tested; config
rejects 0. Full suite green.

* fix(review): harden #62 timeout tests and drop a dead reap flag

- test(node): cover the `protocol error` arm of git_service_app_error
  independently (the input has no "bad line length" substring, so it
  isolates the second classifier arm and goes RED if that arm is removed)
- test(node): make the reap-before-return test's grandchild IGNORE SIGTERM
  (`trap "" TERM`) and outlive the ~4s reap cap, so the SIGKILL escalation
  is load-bearing. Previously the grandchild self-exited under the cap, so
  neutering the SIGKILL still passed; the escalation was exercised but not
  required. Verified: RED with SIGKILL disabled, GREEN with it.
- test(node): add a receive-pack timeout test. Every prior timeout test used
  an upload-pack fake; this proves the push path (which also holds the repo
  write lock) is bounded too. RED-verified with the internal timeout removed.
- test(node): poll for the pidfile in the reap-before-return timeout test
  so a loaded runner can't false-panic before the fake git writes it
- remove the redundant `sigkilled` guard in reap_group_on_timeout; step
  == 200 fires exactly once in the 0..400 loop, so no re-entry guard is
  needed and the SIGKILL still fires exactly once

* fix(node): log malformed receive-pack as warn, not error (#165)

git_receive_pack's error classifier routed every non-Timeout error,
including client-caused BadRequest (400), through tracing::error!. Mirror
the git_upload_pack arm so a malformed push logs at warn level instead of
as a server error.

* test(node,git): make smart_http timeout tests pass under the parallel runner (#165)

Addresses jatmn's review of 41eca0b.

[P2] The #62 timeout tests failed under `cargo test --workspace`:
- run_git_service_tears_down_group_when_future_dropped re-polled a completed
  future ("async fn resumed after completion"): the advance-until-pids loop
  ignored the timeout's Ok(_) (future-finished) case and polled the resolved
  future again. It now breaks on early completion.
- Under fork-storm load a freshly-written fake `git` transiently fails to exec
  (ETXTBSY) or is timed out before recording its pids. Added a
  fake_git_run_with_pids retry helper (used by the four pid-reading tests) plus
  a matching inline retry on the drop test, with growing backoff for the
  correlated bursts and a 12-attempt cap that still fails loudly on a genuine
  never-spawns regression. Reverted two tests from a speculative 2000ms bound
  back to 300ms/1000ms now that the retry covers the timeout-vs-pidfile race.

[P3] Documented GITLAWB_GIT_SERVICE_TIMEOUT_SECS in .env.example and the README
config table (default 600; bounds upload-pack/receive-pack, not info/refs or the
withheld-blob path).

The tests stay load-bearing: breaking process_group(0), the post-reap disarm,
the timeout-arm reap, or the internal timeout each still turns the corresponding
test red (mutation-verified).

beardthelionandt d00d89ae5b fix(node): gate POST /api/v1/sync/trigger and rate-limit the peer-sync routes (#82) (#161)
* feat(node): add per-client-IP limiters + knobs for the peer-sync routes (#82)

Plumb two dedicated per-IP RateLimiters into config/state so the peer-sync
enqueue routes can be braked independently: sync_trigger_rate_limiter (tight,
GITLAWB_SYNC_TRIGGER_RATE_LIMIT, default 60/hr) and peer_write_rate_limiter
(generous, GITLAWB_PEER_WRITE_RATE_LIMIT, default 600/hr). Both are bounded and
swept by the periodic cleanup loop, keyed via the node-wide push_limiter_trust.
No route is wired to them yet; that lands next.

* fix(node): require a signature on /sync/trigger and rate-limit the peer-sync routes (#82)

/api/v1/sync/trigger was reachable unauthenticated in the default config and
drove an O(peers) outbound fan-out + per-repo sync_queue enqueue — an anonymous
amplification/DoS. The same enqueue_sink is reachable via /sync/notify, which
also accepts unsigned known-peer requests and had no rate limit.

- Move /sync/trigger into its own always-signed route group (add_auth_layers),
  independent of require_signed_peer_writes, and give it a tight per-IP brake.
- Add a separate, generous per-IP brake to the peer-write group
  (/peers/announce, /sync/notify); notify's signature behavior is unchanged
  (rolling-upgrade compat), it only gains the brake. Separate buckets so an
  unsigned notify flood can't drain the signed trigger caller's quota.
- Per-IP (not per-DID): a did:key farm self-registers, so a signature/per-DID
  gate does not cap cost (INV-10); the brake keys on the client IP before auth.

Adds an adversarial test matrix (unsigned->401 both modes, IP flood->429,
DID-agnostic brake, forged X-Forwarded-For can't bypass, notify flood->429,
distinct-IP not throttled, cross-route non-exhaustion, 0-disables-but-sig-holds,
announce still accepts unsigned).

* fix(gl): surface node denial on sync trigger and sanitize the error body (#82)

Now that the node gates /api/v1/sync/trigger behind a signature and rate limit,
'gl sync trigger' must not render a 401/429 as a fabricated '✓ sync triggered /
0 peers' success. Check resp.status() before parsing; on a non-2xx, extract the
node's message and bail. Strip C0/C1 control bytes from the node-supplied string
before printing (INV-6) — a hostile node could embed ANSI/OSC escapes in the
body. Adds mockito tests: 401/429 surface as errors (RED without the status
check), control bytes are stripped, and the 200 path is unchanged.

* fix(review): bound gl error-body read, strip bidi controls, genericize 429 message (#82)

Code-review follow-ups on the #82 change:
- gl sync trigger: read the node error body with a capped reader
  (read_body_capped) instead of resp.text(), so a hostile/broken node can't
  force an unbounded allocation to surface a denial (INV-6, read half).
- sanitize_node_msg: also strip Unicode bidi/format controls (U+202A-202E,
  U+2066-2069, LRM/RLM/ALM) — is_control() only covers the Cc category, but a
  right-to-left override can reorder the displayed error line.
- too_many_requests(): the shared per-IP 429 middleware now serves the peer-sync
  routes too, so drop the push-specific wording ('rate limit exceeded'); the
  push-specific 429 in the receive-pack handler is unchanged.
Adds tests for the bidi/length sanitize and the oversized-body path.

* test(#82): close reasoned-not-run gaps with load-bearing tests

Executes the branches that were previously only reasoned:
- read_body_capped byte-cap test (RED against resp.text() — 2MB body -> ≤cap):
  vets the bounded-read fix, not just the display cap.
- sync-route 429 body asserts 'rate limit exceeded' and NOT 'push' (RED before
  the message was genericized); also finishes genericizing the warn log, which
  the response-body change had missed.
- real RFC 9421 signature through the full router reaches the handler (200) in
  both config modes — the positive path through the actual gate, not a
  direct-mount with an injected DID.
- /peers/announce flood -> 429 (the peer_write brake covers announce, not just
  notify).
- trigger_counts extraction unit test (happy + malformed -> 0,0), closing the
  count-formatting gap in the 200 path.
No production behavior change beyond the warn-log wording.

* fix(#82): require an identity for sync trigger and fix the rollout docs

Address review feedback on the always-signed /sync/trigger route.

- gl sync trigger now requires a local identity via load_keypair_from_dir and
  fails locally with "identity not found" before issuing a request, instead of
  .ok() silently sending an unsigned request that can only 401 remotely. Add a
  test proving it fails before dialing the node.
- Split /sync/trigger out of the staged unsigned peer-write rollout in the
  README and the OSS-readiness audit; only /peers/announce and /sync/notify keep
  the rolling-upgrade unsigned behavior.
- Reorder the two peer-sync rate-limit vars in .env.example for dotenv-linter.
- Bump crossbeam-epoch to 0.9.20 (RUSTSEC-2026-0204), matching main, so cargo
  audit passes.

Kevin CodexandClaude Opus 4.8 06388ec26a feat(gl): sanctioned iCaptcha client flow + secure git lifecycle (#138)
* feat(gl): sanctioned iCaptcha client flow + secure git lifecycle

Builds the client side of the iCaptcha gate so a legitimate agent passes the
challenge transparently, with no manual headers and no GITLAWB_ICAPTCHA_PROOF
env var. Server enforcement is unchanged.

New crate `icaptcha-client` (blocking, shared by gl + the git helper):
- deterministic solvers for the computational challenge types (arithmetic,
  algebra, sequence) matching the iCaptcha generators; anagram/logic/LLM fall
  back to a solver hook / interactive prompt.
- obtain_proof(): POST /v1/challenge (requesterId = caller DID), solve, POST
  /v1/answer, handle escalation, return the signed proof. Optional bearer auth
  via GITLAWB_ICAPTCHA_API_KEY.

gl (crates/gl):
- http.rs: unify post/put/delete through one signed sender that, on a 403
  iCaptcha challenge (detected via x-icaptcha-url / x-icaptcha-level headers),
  solves it and retries the same signed request with the x-icaptcha-proof
  header (bounded retry absorbs the ~5 min proof TTL). Removes the env hack.
  Emits an actionable hint on 401 not_an_agent (old-CLI / unregistered).
- repo.rs: `repo info` checks status and returns a real 404 instead of a stub
  card with `?` fields; `repo info`/`clone` resolve the owner from the local
  identity or an explicit owner/name — never the node's own DID.
- doctor.rs: warn on gl-vs-node version drift; add an iCaptcha reachability
  check.

git-remote-gitlawb: same shared client — push stays signed (RFC 9421); on a 403
iCaptcha (safety net; push is signed-only, not gated) it solves and retries.
Clone/fetch unsigned; missing repo keeps its clear 404.

gitlawb-node: the 403 icaptcha_proof_required response now advertises the
service url + required level as JSON fields and x-icaptcha-url / x-icaptcha-level
headers (mirroring the human_detected pattern) so clients discover them instead
of scraping the message. The sub == authenticated-DID and expiry/level checks
are unchanged — enforcement is not weakened.

README: documents the full lifecycle (identity -> register -> repo create with
auto-iCaptcha -> push -> clone), the requesterId == DID rule, and proof TTL.

Tested: solver unit tests; full workspace green against Postgres (node still
rejects missing/expired/wrong-subject proofs).

* fix(icaptcha-client,gl): address PR #138 review feedback

Rebased onto main (resolving the git-remote-gitlawb/main.rs conflict from #119)
and addressed the review findings:

- [beardthelion P2 / jatmn P2 / CodeRabbit] Removed the dead iCaptcha retry loop
  from the push path. git_receive_pack never calls verify_request (only
  create/fork/register are iCaptcha-gated), so a push 403 never carries
  x-icaptcha-* headers and the loop could never solve. Taking main's push path
  (via #119) deletes it, which also resolves the pack-clone (retries no longer
  copy the whole pack) and the interactive-prompt-over-git-stream threads, and
  restores the sanitized info/refs error path. git-remote-gitlawb no longer
  depends on icaptcha-client.

- [beardthelion P1] Sanitize and length-bound iCaptcha error bodies before they
  reach the terminal. The origin is only as trusted as the node that advertised
  it, so its non-2xx bodies (and Failed{reason}) are attacker-influenceable; they
  went raw into bail! (CWE-150, the #137 class). Now bounded-read + C0/C1-stripped
  + capped, same shape as #137.

- [beardthelion P2] Do not trust or hand credentials to a node-chosen iCaptcha
  URL. x-icaptcha-url was used as the base with no scheme/host check and the API
  key was sent to it on the first hop (SSRF + key exfiltration). resolve_solver_url
  now honors an advertised URL only when https + host-allowlisted (public default
  or the operator's GITLAWB_ICAPTCHA_URL), else falls back to the trusted origin;
  the API key is attached only to the operator's own configured origin.

- [jatmn P2 / CodeRabbit] gl repo clone with a bare name now derives the short
  owner key via resolve_owner_did, matching the other commands' gitlawb://z.../name
  URL shape instead of the colon-bearing full DID.

Skipped (with reason): jatmn P3 (doctor GITLAWB_ICAPTCHA_URL) is resolved by the
P2 change — that env var is now read by the write path, so the doctor's probe is
accurate. CodeRabbit User-Agent-version nit lived in the push code reverted to
main. README push wording kept ("signed-only, no per-push challenge") — now
accurate since the retry path is gone; the API-key bullet was updated for the new
trust model.

Tests: added sanitize + resolve_solver_url unit tests; full workspace green.

Kevin Codex 3f08d9936b Release automation (#127)
* ci(release): add Windows target and cross-platform packaging

Add x86_64-pc-windows-msvc to the release matrix. Windows ships a .zip
(7z) while unix keeps .tar.gz; a portable sha256 helper handles
sha256sum/shasum/certutil. Smoke test and packaging now resolve the
.exe suffix on Windows. Release attach uses globs to cover both formats.

* feat(release): vendor npm wrapper and auto-publish to npm

Vendor the @gitlawb/gl npm wrapper (optionalDependencies platform-package
pattern) into npm/, replacing the standalone gl-npm repo. A new npm-publish
job downloads the four unix release tarballs from the GitHub release, lays in
the binaries, stamps every package.json with the release version, and runs
npm publish --provenance. Guarded on NPM_TOKEN so it no-ops until the secret
is configured.

* feat(release): auto-bump Homebrew tap on release

Add a homebrew-bump job that regenerates Formula/gl.rb in Gitlawb/homebrew-tap
from the release tarballs' sha256 checksums (macOS+Linux, arm64+x64) and pushes
the bump. Guarded on HOMEBREW_TAP_PAT so it no-ops until the secret and tap repo
exist. Enables 'brew install gitlawb/tap/gl'.

* feat(release): Windows installer and web auto-sync on release

Add install.ps1 (Windows PowerShell installer, source of truth in node).
Add a web-sync job that opens a PR to Gitlawb/web on each release syncing
install.sh + install.ps1 + public/version.json, plus idempotent drift fixes
(remove orphaned public/bin, fix stale skill.md releases link). Guarded on
WEB_SYNC_PAT. Vercel deploys on merge.

* docs(readme): document npm, Homebrew, and Windows install methods

* ci(release): build only CLI binaries on Windows

The gitlawb-node daemon targets Linux/macOS; building it on Windows risks
a compile failure that would block the whole release (npm/brew/web jobs all
depend on release-binaries). Windows now builds only gl + git-remote-gitlawb;
the smoke-test and package loops follow the per-target binary list.

* fix(release): reconcile release-please manifest with v0.3.9 and bump action to v5

The manifest still said 0.3.8 while the only tag is a manual v0.3.9 and
Cargo.toml is 0.3.9, so release-please had no valid baseline (no v0.3.8 tag)
and never cut a release. Set the manifest to 0.3.9 so release-please diffs
v0.3.9..main and opens a proper release PR for the next version. Also pin
release-please-action to v5.0.0 to match the openclaude pipeline.

* ci(release): set explicit minimal permissions on homebrew-bump and web-sync

CodeQL flagged both jobs for lacking a permissions block, leaving GITHUB_TOKEN
at broad default scopes. Both only need contents: read (cross-repo writes use
dedicated PATs).

* fix(release): harden installers and workflow per review

- install.ps1: fail closed if the .sha256 cannot be fetched; pure ASCII (no BOM)
- npm install.js: fail (exit 1 / throw) when the platform payload or a binary is
  missing instead of reporting a successful but broken install
- workflow: top-level permissions {} + persist-credentials: false on read-only
  checkouts
- docs: PowerShell-only Windows note; text language tag on npm/README fenced block

* fix(installer): require core CLI binaries on Windows

install.ps1 only failed when zero binaries were present, so a partial archive
missing gl.exe could still report success. Require gl.exe + git-remote-gitlawb.exe
(gitlawb-node.exe stays optional, matching the Windows build) and fail early if a
required binary is absent.

* ci(release): make Windows non-blocking and stop persisting cross-repo PATs

- release-binaries: continue-on-error for the Windows leg so a failure there
  no longer fails the job or blocks npm/Homebrew (matches the best-effort intent)
- homebrew-bump/web-sync: persist-credentials: false on the PAT-backed checkouts;
  supply the token only on the git push via an x-access-token URL

* fix(release): gate web-sync on binaries and detect native arch in installer

- web-sync now needs release-binaries so the site never advertises a release
  whose artifacts failed to build
- install.ps1 reads PROCESSOR_ARCHITEW6432 before PROCESSOR_ARCHITECTURE so a
  32-bit PowerShell host on x64 Windows is not wrongly rejected

* ci(release): make npm publish idempotent across reruns

Skip any @gitlawb package version already on the registry so rerunning the
job after a partial publish no longer errors on the first existing package
and leaves the wrapper/platform packages out of sync.

* fix(release): harden web-sync and tap commit per review

- web-sync: verify the Windows ZIP + .sha256 exist on the release before
  syncing install.ps1/version.json (Windows is best-effort, so a failed leg
  must not make the site advertise a missing installer)
- stage generated files before the no-op check so brand-new untracked files
  (formula, version.json) are committed instead of skipped
- gh pr create: only swallow the 'PR already exists' case; surface auth/API errors
- npm README: scope npm/yarn/pnpm/bun install to macOS/Linux/WSL, point native
  Windows at the PowerShell installer

* ci(release): guard npm-publish before doing any work

Check NPM_TOKEN in an up-front guard step (like homebrew-bump/web-sync) and
skip checkout, release downloads, extraction, version rewrites, and publish
when it is absent, instead of doing all that work and bailing in Publish.

* fix(release): robust web PR error handling and Windows installer hardening

- web-sync: capture gh pr list output so a real API/auth failure surfaces
  instead of being misread as 'PR already exists'
- install.ps1: enforce TLS 1.2 and use -UseBasicParsing so downloads work on
  stock Windows PowerShell 5.1; remove binaries no longer shipped on upgrade so
  an in-place update can't leave a mixed-version install; handle an empty user
  PATH without a leading separator
