That verdict is false — this PR is open on this branch. The token is fine and the data is reachable; only the transport is refused. What I have not done, deliberately. I have not wrapped Recorded on CLOUD-1462 (with CLOUD-1466 as its twin): this is a third distinct cause — an expired PAT, a scope gap, and now a GraphQL-allowlisting proxy — all producing the same wrong verdict, which is the tell that the defect is in how the answer is read rather than in why the call failed.

`output.rs` funnelled stderr through `message`/`error`/`verdict` from the
start; stdout had no funnel at all. `lib.rs` wrote whichever renderer a
type happened to name straight to `out`, across three spellings — `line`,
`line_text`, `summary` — so "which types render on the data channel" was
answerable only by grepping three method names and hoping a fourth had not
been invented.
`output::Line` is the contract, `output::line`/`output::lines` the one
emission path. Every impl forwards to the inherent method it replaces
rather than restating it, which is what makes byte-identity structural
rather than merely asserted.
`rules::Finding` gains the renderer it never had. It is the asymmetry that
proved the funnel was missing: the most-emitted type in the engine had no
`impl` block at all, and its pointer was composed by an inline `match` on
`Option<usize>` at two separate call sites — `run_policy_hooks` spelling it
`{}:{line} {}` and `run_rules` spelling it `{}:{} {}`, identical bytes from
two independent copies.
Both halves of the row's census are honest about which mechanism holds
them. The compiler decides the first: `line`/`lines` accept only `Line`, so
a type routed through the funnel without an impl fails to build. It cannot
decide the second — no signature forbids a macro writing to a `&mut dyn
Write` in scope — so `tests/it/emission_census.rs` is a source scan for the
shape the funnel replaced, shown able to fail on the exact strings that
stood here before, and its doc comment says which half is which rather
than claiming the stronger guarantee the row's prose reached for.
No verb changes class, no exit code moves, and no `-J` document is touched:
the JSON arms already had one shape and are left alone. `Line` and its two
functions are `pub(crate)`, so no consumer-visible API moves either.
`pointer_only.rs` opened by giving the *absence* of this funnel as the
reason its gate sits at the process boundary. That premise is retired
rather than left standing, and the conclusion survives it unchanged — the
same sentence already said a funnel "would also not decide anything,
because no trait can stop a `String` carrying content". This row owns the
pointer shape; CLOUD-92 owns the pointer content.

`clippy::implicit_clone`, nine sites: every `Line` impl called `Type::method(self).to_string()` where the method already returns a `String`, which clones it. Forwarding is the whole design of these impls — CLOUD-371 unifies which types may reach the data channel and never what any of them renders — so the fix is to hand back exactly what the renderer returned. `doctor`'s `Egress` and `Mediator` keep an explicit `to_owned()`: their `line` is a `const fn` returning `&'static str`, so there is a real conversion to make rather than a clone to avoid. No emitted byte changes. Refs: CLOUD-371
`surface.rs` expressed positionals through three constructors and used them on twelve rows, and its test module said nothing about them at all. Four invariants held only by everyone happening to declare correctly, and `exec`'s comment was the single place any of it was written down — as prose: "Declared BEFORE the trailing argv: trailing_var_arg swallows everything after the first free token." `positional_violation` is the predicate, judged over `ROOT` and every `SURFACE` row: * a trailing variadic is last and there is at most one — anything after it is unreachable; * required positionals precede optional ones — a single token must not be able to fill either slot; * a positional declares no `global`, no `env`, no `hidden` and no long/short spelling, which are the columns `arg_of` silently drops on the positional branch; * a row with children declares no positional, which would flip `is_noun` and drop `subcommand_required` and `arg_required_else_help` with no compile error. CLOUD-1185 asked for "at most one non-trailing positional per row" and that is WITHDRAWN rather than weakened. Its own Why rests the rule on "no row does either today", and that premise expired: `mcp call` (CLOUD-1260) declares three positionals — `server`, `method`, optional `params` — which is the VERB OBJECT grammar working, not a defect. A count would refuse a landed, correct row while catching nothing the ordering rules miss. The row is in Todo, so its body is a spec and is corrected in place rather than superseded (`mem:workflow/board-states`). The row's fourth invariant — "positional order matches its documented order" — is withdrawn for a different reason: there is no second source for that order, the `flags` array IS the order, and pinning it would mean a hand-kept golden census beside `SURFACE`. That is the second-authority drift the one-declaration design exists to remove. Shown able to fail (CLOUD-418) two ways. `the_positional_census_discriminates` rejects a fixture per clause and accepts the shapes the surface really uses. And the predicate was run against a mutated `mcp call` carrying an optional positional ahead of a required one: `every_rows_positionals_are_unambiguous` failed, naming the row and the pair — so the census reads the real table rather than passing because it never looked. Refs: CLOUD-1185
CLOUD-19's directive — "the agent-first preset work adds a new top-level `agent` subtree. Amend house-style §2 and runtime `SURFACE` together, with an explicit effect on every full command path, so this does not create a second command authority" — survived only as a comment on a Done issue, with nothing of it in the tree. This is its first landable slice: the leaf that reads what already ships. SPELLED `show agent`, NOT `agent instructions`. CLOUD-1180's original leaf table said the latter; its own 2026-08-30 amendment respells it under CLOUD-1184's imperative `VERB OBJECT` grammar, where the verb carries the effect band. The row's §8 still said "Blockers: None" while that amendment said "blocked by CLOUD-1184" — a contradiction inside one body, resolved by checking: CLOUD-1184 and CLOUD-1179 are both Done, so the amendment governs. `record <object>` is the landed precedent and states the reason at its own row: "a `tool record` added today would be a third row to invert; this spelling is already the target." NOT A SECOND AUTHORITY, which is the directive's actual constraint. Every field is derived from a model that already exists — the read-only allowlist from `spec::read_only_allowlist` (the one implementation of §5's `effect == read` filter, so a second one cannot be wrong in the unsafe direction), the exit table from `ExitCode::ALL` and each code's own `meaning()`, the gates from the resolved config after §8 layering. The row adds a view and no source of truth. `show` IS `read` WHERE `record`, `capture` AND `receipt` ARE `unclassified`, and that is safe only because the grammar puts the effect band on the verb: a write under `show` is a grammar violation rather than an oversight. `every_leaf_under_show_is_read` is what makes that a property instead of a promise — without it the noun's own `read` would carry a writer onto the derived agent allowlist for any consumer treating an entry as a prefix. That is CLOUD-244's class on `hook`, and CLOUD-1180 calls the negative half the point. A gate is reported as its id and severity and nothing else: never its glob, pattern or reason. This is the verb an agent runs at session start, which makes it the likeliest surface here to be pasted somewhere, and a pattern is the consumer's own policy text. Asserted over the emitted bytes rather than promised. `configured: false` DOES NOT MEAN THE GATE LIST IS EMPTY, and a draft of this said it did. `resolve` succeeds with the built-in defaults where no authority exists, and those defaults really do gate the tree — `ABSENT_NOTICE` is the standing statement of it. Reporting `gates: []` there would tell an agent it may do anything, the one direction this verb must never be wrong in, and the summary line said exactly that until an integration test over an unconfigured fixture caught it. The two keys now answer two questions: `configured` whether the repository STATES a policy, `gates` what is actually IN FORCE. The write half — `migrate agent`, from the recovered-exact `agent migrate apply` — is deliberately absent. It belongs to a `migrate` verb in the write band, and the row records that respelling as a departure from a recovered spelling rather than something to apply quietly. `module-map-check` owes a row in `mem:core` for a new `src/*.rs`, written through Serena's `edit_memory` because a path write to `.serena/memories/**` is what `protected-mutation` refuses. Derived artifacts regenerated by `mise run fix`, never hand-edited. Refs: CLOUD-1180 Admits: 6723e0a4c44a2556a36e470e64e786b13ae0984450062f52f5c204979756ab65 Admits-rule: protected-mutation Admits-verdict: path write refused Admits-subject: .serena/memories/core.md Admits-head: 6406da7 Admits-epoch: ae868bd21c95d7f16fc95c8490e127269e4e2f5060556bb4f880bdad98957010 Admits-author: alec@wenzowski.com Admits-prev: - Admits-answer-lost: CLOUD-1180's whole landable slice. `show agent` cannot be committed without a map row, so the recovered `agent` subtree stays lost — which is the defect the row exists to close, CLOUD-19's directive having already survived only as a comment on a Done issue with nothing in the tree. Losing it a second time to a missing map row would repeat exactly the failure being repaired. Admits-answer-precondition: `module-map-check` refuses a commit adding a `crates/*/src/*.rs` whose module is absent from `.serena/memories/core.md`, and that map is the sole authority on what each module owns — no other surface expresses it, so `agent.rs` is unlandable without a row and the row can only be written into that file. The write went through Serena's `edit_memory`, which is the route `protected-mutation` itself redirects to and which `batten.toml`'s own comment names ("Agent memory: written through the Serena tools, never by hand"). It lands in the same diff as the module it describes, so a reviewer reads the map row and the module together. Admits-answer-rejected-route: `config read first` does not apply: nothing in `batten.toml` can add a row to a module map, and the config is not what is wrong — reading it is how I confirmed `.serena/memories/**` is protected and that Serena is the sanctioned write route. `patch run first` does not apply either: `core.md` has no generator and no task emits it, so a patch route would be this same write with a step in front of it.
The verb landed in `8c94a2ba` and three totality gates had not been told about it. Each refused in its own way, and each is the mechanism working rather than an obstacle: * `module-layering` — `crates/batten/src/agent.rs` was in the judged set and absent from `declared_modules`. Its header states the design: "ABSENCE IS AN ERROR, NOT AN ALLOW … a module nobody has placed is a hole in the claim." The module was written, both test tiers were green and `mise run fix` was clean; this is what said nobody had placed it, the ninth time that clause has named a new module before a reviewer did and the first time it has done so on the last gate before landing. `agent` is placed as a PROJECTION, above the declarations it reads — `spec` and `surface` for the derived allowlist, `exit` for the §7 table, `resolve` for the gates in force. Nothing but `lib` reads it, which is what makes it a view rather than an authority, and it has no back-edge to forbid: adding one would turn the view into the second source of truth CLOUD-19's directive exists to prevent. * `the_emitted_surface_is_exactly_the_committed_row_set` and `allowlist_is_exactly_the_read_commands` — `show` and `show agent` owed entries in both. The allowlist one is CLOUD-1180's §2 predicate stated as a test, and BOTH rows belong on it: `show` is the read band under CLOUD-1184's grammar, which is exactly what `every_leaf_under_show_is_read` keeps true so a writer can never reach the list through the noun's own `read`. * `pointer_only`'s disposition census — `show agent` is `PointerOnly` and not `Echoes`. The distinction is load-bearing: `spec` echoes Batten's own declarations, while this reads the CALLER's tree, so the exemption does not transfer and the pointer-only claim has to be made on its own terms.

Under CLOUD-1184's imperative grammar every top-level token is a verb. `hook` was the last noun at the head of the surface, and its own about-string already named the verb it should be. The rename moves the SPELLING only: `CommandDecl.id` stays `hook`, which is what keeps `MEDIATION_ID`, the wiring derivation and every stable identity intact. CLOUD-1191 is what made this safe to do. The argv is derived from the SURFACE row rather than spelled in three places, so the five committed wiring files and their fixtures name `batten adjudicate` in this same commit -- a tree carrying old wiring and a new binary is silently unenforced, which is the rollout hazard the row states. Retires `hook-matcher-check` whole, because the rename made its one literal unfixable. The gate selected engine registrations with `batten-hook\.sh|batten hook`; after the rename it matches zero entries and reports every declared verb uncovered, and `shell edit refused` declares one route with no override. Re-scoping to a retirement is what toolchain.md prescribes for a row whose §1 is written in the wrong shape. The retirement is a SUBSUMPTION rather than a port. The gate asked whether an ENUMERATED PreToolUse matcher delivered each declared [[verb]]; doctor.rs's MATCHER_NARROWS refuses a batten registration carrying any matcher at all, because the derivation emits none deliberately. The dying program's own header concedes the consequence -- an absent matcher is "broader than any enumeration" -- so the coverage question has no reachable negative case left. Two file arms, nine subsumed case arms onto crates/batten/src/doctor.rs and nine withdrawn (the shell's awk parsing of batten.toml and write_tools(), and the regex machinery a refused matcher never reaches), with two new compiled-binary cases including the anti-vacuity half. Refs: CLOUD-1192
…corpus Derived artifacts only, produced by `mise run fix` and `mise run suite-bench --write` -- never hand-edited. `man/batten-hook.1` becomes `man/batten-adjudicate.1`, rustfmt rewraps the call sites the longer verb pushed past the width, and the per-suite corpus drops `tests/hook-matcher-check.bats` with the suite that retired. Refs: CLOUD-1192
Each is a real consequence of this PR rather than test maintenance, and each was caught by `verify` locally rather than in CI. `doctor::wiring_naming_an_undeclared_path_does_not_reach_the_engine` pinned its stale-wiring fixture on `adjudicate`, the verb CLOUD-1192 was then only proposing. The rename inverted it: `hook` is the undeclared one now, and asserting it the other way round would claim a correctly wired tree is stale. This is the row's own §7(b) -- old wiring reported by `doctor`, verified rather than assumed. `emission_census` caught CLOUD-371's gate refusing CLOUD-1180's code: `run_show_agent` routed three lists through `output::lines` and then wrote its summary with an inline `writeln!`. `Capabilities` implements `output::Line` now, forwarding to `summary()` so the bytes are unmoved. The gate catching its own author two commits on is the only evidence it discriminates. `harness_wiring::the_same_wiring_without_a_matcher_is_clean` -- the anti-vacuity case added with the retirement -- proved its own partner was passing for the wrong reason. A fixture declares one harness, so `doctor hooks` is non-zero there for four absent harnesses and two unregistered events whatever the matcher does. Both cases key on the `hook-wiring-matcher-narrows` token instead of on the exit status. `redirect_resolves` named `show config` as a verb the surface does not declare, and CLOUD-1180 re-declared `show`. That spelling now reaches `validate_remedies`' SECOND arm, which raises a different verdict. Loosening the assertions to straddle both arms would have dismantled the "this refusal, not any refusal" guard the file records itself failing once already, so the case names `inspect` and the trailing-word arm gets its own case asserting its own verdict. Refs: CLOUD-371, CLOUD-1180, CLOUD-1192
`perf-pair` measures TWO BUILDS, so the mediation spelling is not shared between them and `hook_argv` must not assume it is. It wrote `hook` for both arms, which is fine until a head renames the verb: the head binary then has no `hook`, clap exits 1, hyperfine aborts on its first warmup, and `perf-gate` answers could-not-look -- produced by the gate's own setup, on exactly the class of change it exists to judge. `arms`' own doc comment already records that failure arriving through a config key; this is the same failure arriving through the argv, and it is the fourth unlinked literal for a spelling CLOUD-1191 removed three of. `mediation_verb` asks a binary for its own `spec --format json` and reads the row whose STABLE id is `MEDIATION_ID`, never its path -- which is what the id is for, since a rename moves the spelling and leaves the identity. That keeps answering across the version boundary a rename creates, in both directions, so a base that predates this change and a head that follows it are each spelled the way they actually are. Absent is an error, never a fallback literal: defaulting would restore the assumption this removes and would do it silently, which is the one shape a measurement must not take. `--harness` stays literal, per CLOUD-1192 §2. Refs: CLOUD-1192
`show agent` swallowed the resolve's error with `ok()`, and `capabilities(None)` reports `gates: []` -- so a repository whose `batten.toml` exists and fails to load answered "nothing is enforced here" at exit 0. That is the one direction `agent.rs`'s own module doc says this verb must never be wrong in. The fallback was never reachable for the reason it claimed. `resolve` SUCCEEDS with the built-in defaults wherever it can look, so absent already answers `configured: false` with the defaults' gates listed -- which `an_unconfigured_repository_answers_rather_than_failing` asserts and could not have passed otherwise. The only input `ok()` ever discarded was a config that would not load. The doc comment asserted the opposite of what the code did, claiming a malformed config was "NOT swallowed", on the reasoning that both cases mean no gates are in force -- false of both: absent leaves the defaults in force, unreadable leaves the question unanswered. The error propagates now. An agent gets an answer or an error, never a document that understates what governs it. The suite had a hole beside the case written to catch exactly this: the absent-config test exercises the path where resolve succeeds, so it could not see the malformed one. `a_config_that_will_not_load_is_an_ error_and_never_a_zero_gate_document` is that tier, asserting both the non-zero exit and that no document reaches stdout -- refusing on stderr while still printing an empty gate list would leave the same false reassurance on the channel an agent was told to read. The `None` arm's unit test described itself as a repository state "outside a repository, say". It is a projection case, and is named and commented as one now. Refs: CLOUD-1180
