fix(connector-allow-resolve): give settings the seam config already had - #568
Conversation
`connector-allow-guard` invokes the resolver with no flags, so its suite read the repository's real permission rules. Those rows then asserted production config rather than the adapter's behaviour, and broke the moment that config changed — measured: removing six unenforceable grants from the committed file turned the allow row red, which is how the coupling surfaced at all. `BATTEN_MCP_SETTINGS` mirrors `BATTEN_MCP_CONFIG`; `--settings` still wins. The suite now writes its own fixture and the committed file is no longer an input to anyone's test. That unblocks the removal the new gate was reporting and could not close: the six `mcp__Claude_Code_Remote__*` allow rules are gone. They named tools the connector sets to `always_ask`, which no allow rule at any scope skips — measured across five levers including a PreToolUse hook returning allow — and the toolbox has no owner-facing control to change that, so nothing could ever make them work. The four denies stay and are unaffected: the control never widens a deny, and `connector-allow-guard` still resolves the live uuid and denies `send_later`, which is what AGENTS.md's ban on babysitting timers rests on. Verified after the removal. `mcp-allow-check --session` is green on this repository for the first time since the gate landed. Refs: CLOUD-191 Refs: CLOUD-765 DO-NOT-CLOSE
CLOUD-191 Resolve the connector allowlist per call, from committed policy, whatever name the host chose
CORRECTION 2026-08-18 — the retraction below was itself wrong. This issue stands, with a narrower scope.The "RETRACTED" section further down withdrew this issue on the strength of CLOUD-665's typo diagnosis. CLOUD-665 is false and is now Canceled. The CLI's MCP log tree sanitizes every non-alphanumeric character in a server name to a hyphen before using it as a directory name — The flip is the cause, and this issue's mechanism is the right answer to it. What survives from the detour, and it is the useful half, is the split between the two kinds of server:
So the original reasoning was right about the mechanism and wrong about the victim. An allowlist naming only the readable form does not deny Linear calls; it denies toolbox-server calls, during whichever episodes expose UUIDs. Five allow rules grant nothing and two deny rules enforce nothing for the length of that episode — and the deny side is the worse half, because AGENTS.md's ban on babysitting timers rests on The Ready block below is rewritten to that scope. The original, which reasoned in terms of Linear, is preserved under "Superseded Ready block" for the record. ReadyRefinement gate: Definition of Ready & Done. This body carries only specializations. There is no durable machine. Every session runs in a container that is reclaimed, so a fix written to
Ready predicateA session in which the toolbox server is exposed under a name no committed allow rule matches still has that server's committed allow verbs permitted and its committed deny verbs refused, without a human editing settings and without any UUID appearing in a tracked file. Done
Superseded Ready blockKept for the record; it reasoned in terms of Linear, which the correction above shows is not governed by this allowlist at all. There is no durable machine. Every session runs in a container that is reclaimed, so a fix written to The connector's exposed name is chosen per registration episode, and observation now shows the flip is bidirectional — a single session went readable → UUID → readable. So the failure has no monotone boundary: an allowlist naming only the readable form is correct during whichever episodes land on it, and silently denies every Linear call during the others. The identity is discoverable, so no identifier needs committingThe host writes its injected MCP configuration to That makes a self-healing repair possible with no account-specific identifier in git: read the injected config, derive the server keys present, emit allow rules for them. The mechanism is portable to any account and any fork, and it repairs whichever name the current episode chose. Ready predicateA session that receives connectors under a name no committed allow rule matches reaches a state where Linear calls are permitted, without a human editing settings and without any UUID appearing in a tracked file. Blockers (§8)None. Open questions, in the order they gate the work
RETRACTED — and this retraction is ITSELF retracted (see the correction at the top)The section below withdrew this issue on the strength of CLOUD-665's typo diagnosis, which is false: the log tree sanitizes separators, there was never a misspelling, and the flip is the cause after all. The section is kept verbatim because the reasoning error is the useful part — it is not current. One thing in it is still true and worth keeping: nothing shipped. No Everything from here to the end of the "Done" list is withdrawn. It was written, committed, and reset out of the branch before merging; no ✗ FALSE — there was no typo. CLOUD-665 is Canceled; see the correction at the top. ✗ HALF FALSE — right about Linear, wrong about the conclusion. The connector/toolbox split below is correct and is the useful residue; what does not follow is that this issue dies, since the toolbox server genuinely is governed by ✗ SUPERSEDED — the Ready predicate has been rewritten to the toolbox-server scope at the top, so this no longer describes the issue. Original text: So the Ready predicate is unreachable as written — "a session that receives connectors under a name no committed allow rule matches reaches a state where Linear calls are permitted" describes a state that already holds for reasons unrelated to any allow rule. Back to Todo, unassigned, and it needs re-refining against what is now known before anyone builds again. What may remain: whether the toolbox server's rule matching survives a mid-session flip once the spelling is right. That is a real question and it is much smaller than this issue. RETRACTED: What shipped, and where it differs from the specification aboveThe premise held and the mechanism changed. The Ready block reasoned that the live identity is discoverable, so nothing account-specific needs committing — correct, and the missing half was which discoverable thing to anchor on. Not the key: each entry's
It is a name translation, not a grant. Done
RETRACTED — this residue was residue of the retracted mechanism. CLOUD-663 is being closed as not-a-finding: the memory text it carries describes the same wrong model. The underlying observation it made — that the protected-path gate's redirect names a surface which may not have attached — is real and stands on its own, and is recorded there. Original text follows.
Watch: what a later session needs to pick this upThe trigger is not observable to an agent as a prompt — an agent cannot see its own approval prompts. What it can observe:
So the observation to record, each time it is taken: the session's live connector keys, which form the tool names took, and whether a call succeeded or was denied. Appended to CLOUD-178, which is the evidence thread and is durable when the container is not. That series is what open question 2 needs. It cannot be answered from a single session, and no session so far has recorded it in a form the next one can read. CLOUD-765 A committed allow rule for a tool the connector control sets to `ask` cannot take effect, and nothing says so — the local file claims an authority it does not hold
Why
A claude.ai connector carries a per-tool control owned by the organization.
So a local allow rule for such a tool is not weak, or misspelled, or aimed at the wrong name. It is structurally incapable of doing what it says. The committed file asserts an authority it does not hold, and the only symptom is a prompt that reads as harness behaviour. Measured, 2026-08-20, one session. The generated What it cost, which is the case for the gate. CLOUD-734 read This is CLOUD-380's class on a second host. That issue's root cause is the generalisation never made: one governed host fact (the GitHub branch ruleset) and an unbounded number of ungoverned ones. This is another ungoverned one, on claude.ai rather than GitHub — and unlike CLOUD-380's, it needs no network and no projection to police, because the host already writes its decision to a file on disk every session. What this is NOT. Not a way to obtain the grant: the control is the organization's and the remedy is Customize → Connectors → Tool permissions, never a local edit. The gate reports the disagreement; a human decides which side moves. Widening permissions to suppress the report would be the inverse of what this repository is for. Refinement — Ready (a local rule that cannot enforce itself is reported, from the host's own written decision) Refinement gate: Definition of Ready & Done. This body carries only specializations.

The defect
connector-allow-guardinvokesconnector-allow-resolvewith no flags, and theresolver has an env seam for the generated config (
BATTEN_MCP_CONFIG) but nonefor the settings file. So
tests/connector-allow-guard.batsread therepository's real permission rules: its rows asserted production config
rather than the adapter's behaviour, and broke the moment that config changed.
That is how the coupling surfaced — removing six unenforceable grants from
.claude/settings.jsonturned the allow row red, in a suite that has nothing todo with those grants.
BATTEN_MCP_SETTINGSmirrors the config seam;--settingsstill wins over it.The suite writes its own fixture, and the committed file is no longer an input to
anyone's test.
What that unblocks
The six
mcp__Claude_Code_Remote__*allow rules are removed. They name tools theconnector control sets to
always_ask, which no allow rule at any scope skips —measured across five levers, including a
PreToolUsehook returningallow—and the toolbox has no owner-facing control, so nothing could ever make them
work. They were coverage that enforced nothing, which is what this repository's
own gate exists to report.
The four denies stay and are unaffected. The connector control chooses ask
versus allow and never widens a deny. Verified after the removal:
connector-allow-guardstill resolves the live uuid and returnsdenyforsend_later, which is what AGENTS.md's ban on babysitting timers rests on.mcp-allow-check --sessionis green on this repository for the first time sincethat gate landed — and green because the disagreement is resolved, not because
the gate stopped looking.
