fix: undo a misdiagnosed connector rename, and gate the two session defects it exposed - #489
Conversation
`d503516` rewrote `mcp__Claude_Code_Remote__*` to `mcp__Claude-Code-Remote__*`
on the reading that the server registers with hyphens. It does not. The live
tool this session is `mcp__Claude_Code_Remote__list_sessions`, and calling it
succeeds against the underscore rule that has been committed since `701a7b7`.
The evidence was misread. `mcp-attach-check` reads the CLI's log tree, and that
tree SANITIZES every non-alphanumeric run in a server name to a hyphen — no
directory under it contains an underscore at all. `Apollo.io` logs as
`mcp-logs-Apollo-io`, `Google Drive` as `mcp-logs-Google-Drive`, `Microsoft 365`
as `mcp-logs-Microsoft-365`. So `mcp-logs-Claude-Code-Remote` is the sanitized
form of `Claude_Code_Remote`, and the transform is lossy. A predicate comparing
rule names against those directory names reads the correct spelling as a
misspelling of a name that does not exist. It fired, and the firing was taken as
confirmation instead of as the alternative hypothesis it also fits.
What that landed on `main`, for about an hour:
* five allow rules matching nothing, so `create_session` — the fan-out
primitive `/plan-fleet` and `mem:workflow/agent-fanout` are built on — was
un-granted;
* both deny rules matching nothing, so `send_later` and `create_trigger` were
unenforced and AGENTS.md's ban on babysitting timers was decorative. A
change whose stated motivation was that the ban had been decorative.
Restores the seven rules, removes the predicate and its eight bats rows, and
un-enrols `mcp-attach-check` from `MUTANT_GATES`. Not `git revert d503516`: that
would also revert the early-return fix in predicate 1, and the pre-`d503516` body
is already correct once the predicate that needed it is gone.
The header keeps a note on why the log tree cannot answer the question, because
a bare revert loses the reason and the next reader has the same directory
listing in front of them. The question — does a permission rule name a server
that exists? — is real and needs a source that preserves the name: the exposed
tool names, or the injected MCP config.
What this restores the standing of: CLOUD-178's original diagnosis. The server
is governed by `permissions.allow`, it is refused while exposed under its UUID
because no rule matches a UUID, and it works the moment the readable name
returns — observed live in this session. CLOUD-191, self-healing the allowlist
across that flip, is the right mechanism and is not superseded.

…efault
Nothing here declared one, so it was the host's 30000ms default. Serena is the
only server it governs — the rest are HTTP connectors the host manages — and
that number was never checked against what Serena needs. CLOUD-266's rule
("timeouts are uniform boilerplate, not measured budgets, so they bound nothing")
in the one place nobody had looked.
Measured first, driving the full handshake the client actually performs
(initialize, initialized, tools/list, prompts/list, resources/list):
warm, idle 4.01s
under `mise run ci`, load avg 2.0-2.8 3.21s / 3.83s / 4.47s
host log, warm reconnect 5.39s
host log, COLD SESSION START 16.65s <- worst observed SUCCESS
host log, re-registration x2 >30s, CONNECT_TIMEOUT
`initialize` is the entire cost; the three list calls are 0.00-0.03s each. So
the default gave 1.8x headroom over the worst observed success, and it came up
short twice in one session.
Exceeding it is not a retry. Serena is absent for the WHOLE session, and the
failure reads as ordinary flakiness: `mcp-attach-check` reports
`serena CONNECT_TIMEOUT` truthfully and a session moves on — measured, five
times in one session before anyone opened the log. It takes `.serena/memories/**`
with it, since the protected-path gate routes memory writes through Serena, and
it takes the symbol tools, so navigation silently degrades to grep.
120000, ~7x the worst observed success, because the cost function is asymmetric:
an over-long budget is paid once at startup and only when the server is
genuinely failing, while an under-set one costs every tool Serena owns for the
rest of the session. In `.claude/settings.json`'s `env` — `.mcp.json`'s
per-server `env` cannot serve, being passed to the child while this governs the
parent's wait.
The gate carries the measurement table, since JSON cannot. Floor 60000 rather
than 120000 so the value can be tuned down on evidence without editing the gate,
while still refusing a return to the default. The load-bearing case is `refuses
the host default`: a presence-only check passes 30000, which is the exact state
this fixes, and that is the declared mutation.
What was ruled out, so nobody retreads it — each tested and disproven, not
argued: Serena being slow (4s warm); contention (3.2-4.5s under `mise run ci`);
an overlapping restart or the dashboard port (3s with a second instance, port
never bound); the `mise exec` environment (0.16s under `env -i`); and CLOUD-316's
launch shape, whose narrowing to a single tool is present and correct. An
apparent 34s/52s from the dashboard flags was an artifact of the probe leaving
the previous instance running, and is discarded.
Not claimed: why the two re-registration attempts exceeded 30s. Nothing
reproducible does, and this change does not depend on knowing — it is justified
by the worst observed SUCCESS. Also unaddressed and filed separately: no
persistent rust-analyzer cache exists, so every start pays a full cold index.

Signing is good, and CI signing with a published key is where CLOUD-591 is
going. What this refuses is narrower and worse than not signing: a signature
produced by a key that cannot be verified or reproduced. It looks like
provenance and carries none.
CLOUD-591 recorded the interim posture and shipped no mechanism, so it was never
once in force. The launcher writes the signing configuration `--global` every
session and nothing repo-local answered it. Measured 2026-08-18, all four global
and none local:
commit.gpgsign true
gpg.format ssh
user.signingkey /home/claude/.ssh/commit_signing_key.pub <- 0 bytes
gpg.ssh.program /tmp/code-sign -> /opt/env-runner/environment-manager
Signatures were produced regardless of the empty key file, because
`gpg.ssh.program` substitutes the harness's own signer for `ssh-keygen`. The key
never passes through the configured path and it is the environment's: this repo
does not hold it, cannot publish it, and it need not survive a container.
GitHub answers `verified: false, reason: unknown_key`.
The attribution consequence is why this is a defect and not a preference. Every
commit carried the accountable human in `author`/`committer` — correct, gated by
`identity_deny` — and a vendor-held key in `gpgsig`. `Attribution` carries
`identity_deny`, `trailer_deny`, `body_deny`, `trailer_allow` and `identity`,
and NO signature field, so the one commit field the gate structurally cannot see
was the one carrying a vendor identity. This stands in for that blind spot until
CLOUD-440 lets the engine see a commit object.
WHAT COUNTS AS UNVERIFIABLE, two independent measured conditions:
* `user.signingkey` names an empty file, so the public half cannot be read and
no `allowed_signers` entry can be derived from it.
* `gpg.ssh.program` resolves inside `/tmp`, which the container reclaims, so
the signer and its key are not reproducible across sessions.
A signer failing neither is left alone and signing stays on. Two suite rows exist
only to hold that line — a verifiable signer with `commit.gpgsign true` passes,
and `--repair` leaves it on rather than switching it off — because a gate that
quietly blocked CLOUD-591's end state would be the wrong gate.
The repair rides `session-start.sh` beside `attribution-identity`: same window,
same shape, and for the same reason — repair before the session writes a line,
or the fix arrives after commits only a rebase can unwind. Local-only, never
`--global`; a contributor's unrelated repositories are not this repo's business.
The check rides `commit-lint`'s `BASE_SHA..HEAD_SHA` contract beside
`commit-attribution`, so it gets the local pre-flight and the CI backstop with
no second call site and no `ci-local-parity` edit. History is never judged —
every commit already on `main` carries that environment key and nobody can now
unsign them.
Two defects the build found in itself, recorded because both were nearly shipped:
the first predicate demanded the local override unconditionally, which would have
reddened every CI run for a condition a runner cannot have; and the fixtures
passed by inheriting THIS container's broken global config rather than by the
gate's logic, so they now set their own signer.

…g it `no-branch-f-main` refused `tests/signing-posture.bats:30`, and the rule is right: a `branch -f main` that ever escaped its fixture would move the real trunk, so a suite must not carry the shape at all — not even over a throwaway `git init` where it happens to be contained. The branch was also unread. Every row passes `--base` explicitly, and the two `--repair` rows return before the range is computed, so nothing resolved `origin/main` or `main`. `git init --initial-branch=main` gives the fixture the trunk name it should have had from the start and deletes the line rather than rewording it. Suite unchanged at 16 rows, all green. Refs: CLOUD-669
CLOUD-668 The MCP startup budget is the host's 30s default, never measured — Serena's worst observed successful connect is 16.6s, and it loses the session when it exceeds it
Nothing in this repo sets the MCP server startup budget, so it is the host's default of 30000 ms. That number was never measured against what Serena actually needs, and Serena is the only server it applies to — the rest are HTTP connectors the host manages. This is CLOUD-266's defect ( What it costs when it is exceededNot a retry. Serena is absent for the whole session, and the failure reads as ordinary flakiness:

CLOUD-669 The not-signing posture is prose: the launcher sets `commit.gpgsign` globally every session, so every commit carries an environment key nobody can verify

…wo rows hid it Four defects found in review on #489, each confirmed against the code before being fixed. Two are the same class the repo already has a name for: a row that passes whether or not the predicate is right (CLOUD-418). 1. THE SCAN REFUSED EVERY SIGNATURE, not the unverifiable ones. This file's header promises that "a signer failing neither test is left alone and signing stays on", because signing in CI with a published key is where CLOUD-591 is going. The commit scan ignored that entirely and reported any `gpgsig` in range — so the gate refused the exact end state it promises to permit. The row asserting that promise could not catch it: it commits with `--no-gpg-sign`, produces no header, and never reaches the scan at all. A new row puts a real header in front of the scan with the signer left verifiable, and the three refusal rows now break the signer explicitly, so each says which condition it is exercising instead of relying on a fixture default. The scan is scoped to a broken signer rather than made to verify signatures. Verifying properly needs an `allowed_signers` file this repository does not have, and PUBLISHING one is precisely CLOUD-591's deliverable — so the gate reads the evidence it actually has, the signer configuration, and says so. The two arms stay distinct: `--repair` clears the config arm and leaves the scan firing on what was already written, which is what the declared mutation tests. 2. `[ -s "$key" ]` CALLED A DIRECTORY HEALTHY. `-s` is true for anything `stat` can size, so an unreadable file and a directory both read as a good signer while the public half stayed unreadable — the condition the predicate exists to name. Now `-e`, `-f`, `-r` and `-s`, each with its own reason in the message, and a row apiece. And the file tests would have created a false positive of their own: `gpg.format ssh` accepts the public key INLINE, and a literal is the most publishable form there is. A literal is recognised and left alone, with a row. 3. THE BASE-EXCLUSION ROW PASSED VACUOUSLY. Both its commits were unsigned, so it held whether or not the scan honoured `--base`. The excluded base is now signed with the signer broken — every ingredient of a refusal present except being in range. 4. `mcp-timeout-budget --settings` WITH NO VALUE HUNG. `shift 2` on a single remaining argument shifts nothing and returns non-zero, and the file runs without `errexit`, so the argument loop spun forever. Reproduced at exit 124 before fixing. A hanging gate is worse than a failing one — `verify` and the hk gate both wait on this. Two rows, each under `timeout`, because the assertion is that it terminates. Suites: signing-posture 15 -> 21 rows, mcp-timeout-budget 9 -> 11, all green. Both declared mutations still caught.

AGENTS.md bans PR-webhook babysitting twice over — this task drives the landing loop "no timeout, no cap, never the PR webhook", and no heartbeat may babysit a PR — and the harness armed a subscription on every PR this repo opened anyway: #397, #402 and #489, three occurrences in five days. On #402 and #489 with no `subscribe_pr_activity` call behind it, so a `permissions.deny` row on the tool would close only the path nobody used. The remedy until now was an agent remembering: prose, therefore feedforward only, therefore exactly the half-change non-negotiable rule 2 refuses. `land` now drops it itself — once before the lap, and again after each ready it fires, since a `pull_request` event is what arms one. `unsubscribe_pr_activity` lives on the session's toolbox MCP server, an http endpoint under `/v2/ccr-sessions/` carrying no bearer token, so a JSON-RPC `tools/call` is a plain POST. Both header values are per-session and account-specific, so nothing here commits them: only the public endpoint SHAPE is tracked, and the volatile halves are read at run time out of the injected client config — the entry chosen by the tool it DECLARES rather than by a server id, which is CLOUD-191's endpoint-anchoring pattern applied to a second consumer. The repository is derived from the remote rather than declared, so no slug is a second authority. Failing open is the posture, not a caveat on it. Off harness there is no config, no subscription and nothing to drop, and the silence is the right answer; on harness, a refused or unreachable call costs the lap nothing, because ending a green landing over a nuisance subscription would be a worse defect than the one being closed. The status is dropped at the call site on purpose. The one thing never silent is a call that did not do what it says. Measured while building this, and it qualifies the mechanism rather than the design: a POST from a task is answered 401 by that endpoint today, so the drop currently reports `could NOT drop #N's webhook subscription (http 401)` instead of firing. Recorded on the issue with the reproduction. The shape is still the one the issue specifies, it costs a landing nothing when refused, and it says so rather than reading as done — which is the difference between this and the deny rule the issue already rejected as a placebo. Ten rows in tests/land.bats cover the test obligation: a subscribed PR is dropped and says so, an absent config and a toolbox without the verb are silent no-ops, and a 500, an unreachable endpoint, a JSON-RPC error and an `isError` result each cost the lap nothing while still being reported. Two `#MUTANT` declarations hold them: dropping the call reddens the first row, and reading the call's status at the call site reddens the fail-open row. Refs: CLOUD-518

THE ACTOR DESIGN DOES NOT WORK, and this is not it. `land` making the call itself looks reachable: the tool is on the session's toolbox MCP server, an http endpoint under /v2/ccr-sessions/ carrying no bearer token, so a JSON-RPC tools/call looks like a plain POST. Measured 2026-08-18, that POST is answered 401 at both the toolbox and the github endpoint, with the injected config's own header values, and identically when forced through $HTTPS_PROXY: no_proxy carries anthropic.com, so requests to that host bypass the agent proxy and nothing injects a credential; the two headers are routing, not authorization. A first cut of this change shipped that POST behind a fail-open anyway. It removed zero subscriptions while its suite stayed green against a stubbed curl — a mechanism that reads as coverage and is not, which is CLOUD-418's defect rebuilt by hand. Filed as CLOUD-673. So this is `claim-check`'s inversion, the same one `issue-search-check` uses: the agent can do what the task cannot. The session's own tool call succeeds — that is how all three occurrences were remedied — so the agent unsubscribes, `pr-unsubscribed record <pr>` records that it happened for THIS pull request in THIS session from the tool's own answer, and `land` refuses to spend a runner until the record exists. The rule becomes an exit code without pretending to an effect nothing here can produce. Placement and posture: * The check is the FIRST thing `land` does, before the singleton and the lease, so a refusal costs no CI at all and the fix is one tool call away. * Off harness there is no injected config, therefore no session, therefore no subscription — `pr-unsubscribed` passes silently. That fail-open is what makes it safe on the critical path; a gate that cannot look must never become a gate that blocks everything. * Keyed by (session, PR), because a subscription belongs to that pair. A receipt from a previous container attests to nothing about this one, and #489's answer cannot satisfy #490 — the honest error this is built for, since the harness pins a session to one branch name for a whole engagement. * Pointer-only on stdout and in the receipt: the PR, the session and a digest of the answer. Never the answer, which is a message about a webhook stream. The honest limit, stated in the gate's own header: this proves the call was MADE for this PR, not that GitHub's subscription state is empty. Only the API answers that and reaching it is CLOUD-673. The claim receipt has the identical property, accepted there deliberately — the threat model is honest error, not fabrication. Ten rows in tests/pr-unsubscribed.bats cover both verbs: the refusal, the recorded drop, an answer naming the wrong PR, a receipt from another PR and from another session, empty stdin as could-not-look rather than a refusal, off-harness silence, pointer-only output, and bad arguments. Three rows in tests/land.bats cover the landing: the stop spends nothing (no ready, no push, no comment, no verify), the check names the PR being landed, and a passing gate leaves a lap unchanged. Four `#MUTANT` declarations, and the stopping-condition census moves 27 -> 28 — it caught the new stop the moment it was added, which is what it is for. Refs: CLOUD-518

The near-miss predicate and its eight rows are gone,mcp-attach-checkis un-enrolled fromMUTANT_GATES, and the task now carries a header note recording that the log tree is lossy and cannot answer a question about a server's real name — so the next attempt does not start from the same source.The question underneath is real and is not re-filed as a re-do: it needs an input that preserves the name, and finding one is its own work.

fix(mcp)— the MCP startup budget is set from measurementMCP_TIMEOUTwas left at the host default. Measured against the Serena language server, which is required and pays a full cold index on every container start (there is no persistent rust-analyzer cache): 4s idle, 4s loaded, 3s overlapped, against harness observations of a 16.6s cold success and two timeouts. The budget is now declared in.claude/settings.json— the only file the CLI reads it from, since.mcp.json's per-serverenvgoes to the child process instead — andmcp-timeout-budgetrefuses a value below a stated floor, naming both numbers. The measurement table lives in the task header.Deleting the language server to fit an invented 30s budget was the first thing tried and was wrong; the budget was raised to fit the measurement instead.
3.
fix(attribution)— refuse a signature no one can verify, not signing itselfSigning is good. Signing in CI with a published key is the end state CLOUD-591 is working toward, and two suite rows exist only to hold that line: a verifiable signer with
commit.gpgsign truepasses untouched, and--repairleaves it on rather than switching it off.What this refuses is narrower and worse than not signing — a signature produced by a key that cannot be verified or reproduced. It looks like provenance and carries none. Measured 2026-08-18, all four settings
--globaland none local:Signatures were produced regardless of the empty key file, because
gpg.ssh.programsubstitutes the harness's own signer forssh-keygen. The key never passes through the configured path and it is the environment's: this repo does not hold it, cannot publish it, and it need not survive a container. GitHub answersverified: false, reason: unknown_key.The attribution consequence is why this is a defect rather than a preference. Every commit carried the accountable human in
author/committer— correct, gated byidentity_deny— and a vendor-held key ingpgsig.Attributioncarriesidentity_deny,trailer_deny,body_deny,trailer_allowandidentity, and no signature field, so the one commit field the attribution gate structurally cannot see is the one carrying a vendor identity. This stands in for that blind spot until CLOUD-440 lets the engine see a commit object.Two independent measured conditions define "unverifiable":
user.signingkeynaming an empty file (no public half, so noallowed_signersentry can be derived), orgpg.ssh.programresolving inside/tmp(the container reclaims it, so the signer is not reproducible). A signer failing neither is left alone.The repair rides
session-start.shbesideattribution-identity— same window, same shape, and local-only, never--global. The check ridescommit-lint'sBASE_SHA..HEAD_SHAcontract besidecommit-attribution, so it gets the local pre-flight and the CI backstop with no second call site. History is never judged: every commit already onmaincarries that environment key and nobody can now unsign them.Defects this build found in itself
Recorded because each was nearly shipped:
git cat-file … | sed … | grep -q '^gpgsig'reports failure on a match underpipefail:grep -qexits the moment it matches, the producer takes SIGPIPE, and the pipeline takes the producer's status. The signed commit the gate exists to catch would have read as clean. The suite passed anyway, because a commit header is small enough that the producer finishes first —pipefail-grep-checkcaught what the tests could not. Replaced with a captured header and a shellcase.mainref withbranch -f, whichno-branch-f-mainforbids in a suite for good reason. It now takes--initial-branch=mainatgit init; the ref was never read by any row.Verification
