agent versioning: allowlist the state paths instead of denylisting secrets (tsk-xa76qz) - #2789
Merged
Conversation
… (tsk-xa76qz)
The agent state repo's root IS the agent home (/root) and every commit is a
`git add -A`, so a 19-pattern denylist decided what stayed out of history. It
could not win: the deployer itself writes `/root/.hermes/config.yaml` with the
agent's LiteLLM key and `/root/.openclaw/env` with the bridge token, and
neither matched a pattern. `git check-ignore` on the branch's own
_GITIGNORE_CONTENTS put .hermes/config.yaml, .openclaw/env, .env.local,
.git-credentials, .netrc, .npmrc, .config/gh/hosts.yml, .kube/config,
.bash_history, the committer's own log and the .cache/.local/.venv trees all
INSIDE the repo — committed on the first deploy, served back out as a unified
diff by GET /versions/{sha}/diff, and unscrubbable by key rotation.
The scope is now an allowlist generated from a single constant: `*` ignores
the home directory and _STATE_PATHS re-includes workspace/, memory/ and the
per-framework AGENTS.md, derived from AGENTS_MD_PATHS so adding a framework
adds a state path rather than a secret pattern. That also bounds the scan —
git descends into the allowlisted directories only, never .cache/ or .venv/,
which is what made the 60s `git add -A` timeout a real risk on Pi-class
hardware; the initial commit keeps its own longer budget for a populated
workspace.
Also folded, each with a regression test:
- Unknown revisions are recognised by every wording git uses ("bad revision",
"unknown revision", "ambiguous argument", "bad object"), so `git show` on a
missing sha returns 404 rather than 409 container_unreachable.
- The noop-vs-revert decision moved inside the state flock. It was made from a
HEAD read taken outside the lock, so an auto-commit landing in the gap made
the route answer "noop" while the tree sat on a commit nobody asked for.
- Every terminal committer failure (missing script, failed push, failed nohup)
now raises into the handler that sets versioning=False + versioning_error.
A deploy result claiming versioning=True while no committer ever starts is a
lie no caller can detect.
Docs-Reviewed: no user-facing doc describes agent state versioning yet (the
feature is API-only and undocumented across this whole chain); the versioned
scope is now documented where callers meet it — the agent_git and
routes/agent_versions module docstrings.

…k-xa76qz) Five folded, one refuted in the PR body: - Unknown-revision markers are matched only on git's own "fatal:" lines. A substring search over the container's combined output would read an incus "Error: Instance is not running (ambiguous argument)" as a missing object and answer 404 for an unreachable container. Control test asserts exactly that string still raises ContainerUnreachableError. - A reset that fails on repo state (corrupt index, unwritable .git) now raises GitOperationError, not ContainerUnreachableError. Both are 409, but the class and the response body now say which happened instead of blaming reachability for a repo problem. - _SHA_RE accepts uppercase hex. Object names are case-insensitive to git, and every place a user copies a sha from can hand one over uppercase; a 400 with no recovery but "lowercase it by hand" was the old answer. - _container_name validates the agent name with the same token rule as the remote. "remote:container" is the qualified form, so a name carrying a colon addressed a different remote silently. The exception is renamed to InvalidContainerTargetError since it now covers both halves. - The committer systemd unit uses /usr/bin/env python3 rather than a hardcoded /usr/bin/python3, matching the nohup fallback's PATH lookup, so an image with python3 under /usr/local/bin no longer relies on the fallback to recover. Not folded: _home_relative still raises at import when a framework path sits outside the agent home. That is the intended failure — a repo rooted at the home cannot version a path outside it, and skipping the entry would leave that framework's rules unversioned with nothing to notice. The message now names the fix instead of only stating the violation. Also drops a leftover debug print from the revert test. Docs-Reviewed: route docstring status-code table updated for the widened 400 and 409 buckets; no other doc describes these routes.

CARD TITLE (intent, not commit subject): [lib-audit] Rate limiters: unbounded IP dicts are an OOM on a public route
Autonomous build of board card tsk-4gqiik.
What changed
tinyagentos/rate_limit.pybecomes the one limiter implementation the controller uses:MovingWindowLimiter— "at most N requests in any span of W seconds" per key. Moving,not fixed, so the window has no exploitable edge. Reads
time.monotonic(). Tracks at mostMAX_TRACKED_KEYS = 2000keys, evicting the least recently used (anOrderedDict, soeviction is O(1) — peer.py's sweep-then-LRU was O(n) per insertion once full).
RateLimiter— the token-bucket registry is bounded the same way. An idle bucket hasrefilled to capacity, so dropping the least recently used one is free: recreating it yields
exactly the same full bucket.
TokenBucketgainstokens_at()(non-mutating fill level,now also used by
try_consume) andseconds_until().rate_limited_response()/retry_after_headers()— one 429 helper, so no throttledresponse can ship without
Retry-After.All five limiters the card names now use it: the invite-redeem window in
auth_middleware.py,the cluster manual-claim in
routes/cluster.py, the peer per-contact window inroutes/peer.py,and the two token buckets in
routes/routines.pyandroutes/client_logs.py. The hand-rolledcopies are deleted — including the pair that
auth_middleware.py's docstring promised "mirrors_manual_claim_rate_okexactly so behaviour is identical", which is now true by constructionrather than by comment. Each module keeps its
_rate_limit_hits/_manual_claim_hits/_rate_hitsname as an alias of its limiter's live map, so the existing reset-based regressiontests keep working unchanged.
The
limitsdependency is declined. The mechanism is ~120 lines of stdlib; taOS installsoffline on 4 GB ARM boards where each added wheel is a support cost, and
limitswould pulldeprecated+typing-extensionsfor logic that has to be read line by line during a securityreview anyway. Every DONE-WHEN is met without it, and
docs/audit/library-replacement-audit-2026-09.md§3.1 S5 now records the decision.RED FIRST (pasted)
At
origin/dev(b8f7726), before any production change:The card warned that "the 21st request in a window is 429" passes today, so none of these
assert that. They assert the three properties that actually fail — the registry is bounded,
the window has no exploitable edge, the 429 carries
Retry-After— plus a fourth the cardraised but did not sketch: a backward wall-clock step must not freeze a window.
The boundary red is measured, not assumed: one request opens the window at t=0, 19 more land
at t=9.9 s and 20 at t=10.1 s. The fixed window resets at 10.1 s and accepts 39 inside a
0.2 s span against a documented 20-per-10s cap. The moving window accepts 20 — the single
slot freed by the t=0 hit expiring.

docs/design/cross-user-collaboration.md— peer 60/min/contact is a moving window withRetry-After.docs/audit/library-replacement-audit-2026-09.md— S5 marked done in both the finding tableand the quick-wins list, with the declined-dependency rationale.
changelog.d/tsk-4gqiik-bounded-rate-limiters.md—### Securityfor the OOM,### Fixedfor the boundary, the clock and the missing header.
Scoped out
routes/desktop_browser/push.py:73holds a sixth limiter with the same never-pruneddefaultdict(deque)shape. It is keyed onuser_id, so its key space is the account list —not attacker-controlled, and not the card's defect. Left alone rather than widening the blast
radius of a security fix; noted in the audit row.
Deleted symbols
Two private helpers are gone because the shared limiter replaces them, not because
a stale branch dropped them. Both are unreferenced at HEAD (
grep -rnreturns onlytheir former definitions on
dev):tinyagentos/routes/cluster.py:_manual_claim_rate_ok— the copy thatauth_middleware.py's docstring said it "mirrors exactly"._manual_claim_limiter(a

_manual_claim_hitsand_MANUAL_CLAIM_MAX_PER_WINDOWare kept,so
test_manual_claim_rate_limitedstill exercises the path unchanged.tinyagentos/routes/peer.py:_rate_limit_ok— its private sweep-then-LRU evictionis exactly what the shared limiter generalises (and makes O(1)).

Kilo review findings on this PR (1e22102)
Merge rule: every finding folded or refuted with evidence.
agent_git.py:128— markers matched over the whole stderr → FOLDED. The search is now scoped to git's ownfatal:lines. Control test:Error: Instance is not running (ambiguous argument)— an incus failure quoting a marker — still raisesContainerUnreachableError(409), while everyfatal:wording still gives 404. (The finding'ssuggestionblock was byte-identical to the code it flagged, so the fix here is the described one, not the pasted one.)deployer.py:788—ExecStart=/usr/bin/python3vs the fallback's barepython3→ FOLDED. Unit now uses/usr/bin/env python3, so the systemd path resolves the interpreter exactly as the nohup fallback does. The finding notes this was not deploy-silently-broken (theis-activecheck already routes it to the fallback); folding it removes the reliance on that fallback.agent_versions.py:54—_SHA_RElowercase-only → FOLDED.^[0-9a-fA-F]{7,40}$; git treats hex object names case-insensitively. Test posts an uppercased HEAD sha and gets 200noopinstead of 400.agent_git.py:254— every other non-zero mapped toContainerUnreachableError→ FOLDED. NewGitOperationErrorfor "the container answered, git could not do the work" (corrupt index, unwritable.git). Still 409 — 404 would be a lie — but the class and the response body now name the repo-state failure. Route test asserts 409 carryingfatal: Unable to write new index file, and the docstring's status-code table is updated.agent_git.py:55—_home_relativeraises at import → REFUTED (message improved). Import-time failure is the correct behaviour, not a rough edge: a repo rooted at/rootcannot version a path outside/root, so the alternatives are a loud error or a silently dropped framework whose rules are then unversioned with nothing to notice — the failure mode this card exists to end. What was fair in the finding is the message, which now names the fix (put the file under /root or drop it from AGENTS_MD_PATHS) rather than only stating the violation.agent_versions.py:62—remotevalidated,namenot → FOLDED. Both halves of the container target now go through one_CONTAINER_TOKEN_RE; a name carrying:producedtaos-agent-foo:barand silently addressed a different remote.InvalidRemoteErroris renamedInvalidContainerTargetError(used only in this module) since it now covers both. Test: an agent namedbad:namegets 400, not a misrouted exec.Also dropped a leftover
