The gate had no honest path

conserves obliges every deleted @test to name an arm in crates/batten/tests/*.rs — carried, subsumed or changed. All three name a successor, because the column was written for a bash suite migrating into the engine. A withdrawal has none: the subject is deleted because the feature should not exist, so the honest mapping is that there is nothing to map.

With three arms the only routes past that were:

• a false subsumed — a ledger entry that lies in order to pass; or
• a [[waiver]], which config-lint refuses as waiver-added unless the weakening was groomed onto the issue before the work started. Retrofitting that grooming is laundering, not grooming.

Neither is honest, so this is a gate defect rather than a verdict, and AGENTS.md says a wrongly-refusing gate is repaired in-session rather than ticketed.

withdrawn, and the condition that keeps it narrower than a waiver

The fourth arm is admissible only where the dying file's declared subject is absent at head. That is the whole design: a waiver admits every deletion under its path, while this admits one case at a time and only once the subject went with it. It owes a reason and names no target — there is no successor to name, and demanding one would be the false subsumed again.

One read of "did the subject die", because there were about to be two. The aggregate admission already asked git, and conserve_case_names runs before the aggregate return, so the arm needed the same fact earlier. subject_verdict resolves it once and both consumers read it — a header reader and a tree reader in one decision would disagree on exactly the rebase where it matters. The round trip is skipped entirely when nothing decreased, so a ratchet moving in the permitted direction pays nothing for the column.

Absence stays byte-identical. The fourth token joins the arm list only where a row declares it, and a declared-but-blank one is refused at load, since an empty token matches every line and would claim every case.

The deletion it unblocks

.claude/container-setup.sh and tests/container-setup.bats were added by #709 and are withdrawn here: a Claude-cloud-specific bootstrap around an install path whose whole point is being harness-agnostic. #711 established why it is unnecessary — honouring the CA bundle the environment already declares gets the one-liner through a TLS-re-terminating proxy with no NO_PROXY fencing at all, so the wrapper was solving a problem it had misread.

The ledger splits the eight cases honestly rather than uniformly:

disposition	cases	why
subsumed	1	the off-PATH refusal is install.sh's own behaviour now, covered in tests/install.bats
changed	1	the NO_PROXY fencing became CA-bundle handling — same problem, narrower mechanism
withdrawn	6	they described the wrapper's own existence: which script to prefer, what to fetch, what to verify about the fetched bytes

Shown able to fail, in both directions

• Removing the arm from batten.toml restores exactly six findings — the six withdrawn cases, while the subsumed and changed arms still resolve. That is the arm being load-bearing and correctly scoped.
• Restoring it returns the tree to green.
• a_withdrawal_over_a_live_subject_refuses is the discriminating case: it leaves the subject standing while claiming its cases withdrawn — a suite gutted with a note attached. It asserts at the arm's own line rather than on a reason string, because the aggregate subject-alive blocker fires either way, so a case keyed on that would pass against an arm that honoured every withdrawal.
• Plus: a bare arm is refused while an explained one is not, and a withdrawn: line under a row that does not declare the column claims nothing.
• test:cargo green, test:bats green, batten-check green, config-lint: 0 smell(s).

CLOUD-65 Ship a single-binary-first install path and package-manager distribution

Why
Batten should install as a standalone binary first, then through cargo binstall, mise, and package managers, without committing binaries.

Acceptance

• A one-line install works
• cargo binstall batten works
• No binary is committed to the repository

---

Shipped — PR #310, and what it deliberately does not close

install.sh + [package.metadata.binstall] + mise run install-check land the ordering claim: the binary installs with no package manager, no Rust toolchain and no clone, and every other channel is a convenience over the same release asset. Verified end-to-end against v0.0.61 — a static-pie musl binary reporting batten 0.0.61, verified=sha256.

Acceptance, clause by clause:

• A one-line install works — MET. curl … | sh, verified against the SHA-256 digest the release API reports, with no flag to skip the check. Measured while building it: api.github.com answers pretty-printed JSON, so the parsing commits to neither wire form.
• cargo binstall batten — HALF MET, and the other half is not mine to close. The asset-resolution contract lands and cargo binstall --git <repo> batten works today. The bare registry form needs the crate on crates.io, which CLOUD-205 defers along with the public repository; it starts working on the day that decision is revisited, with no further edit to this repo.
• No binary is committed — MET, and now gated. install-check fails on any tracked file carrying executable-format magic. That clause had no mechanism before.

Deferred, each with a home:

• The digest install.sh verifies is transfer integrity, not provenance — both halves come from GitHub, so it proves the bytes arrived intact, not that they are the bytes a maintainer intended. CLOUD-278 (checksum manifest) and CLOUD-264 (signature format) are the stronger claims; neither blocked this, because the API already carries the digest.
• Package-manager distribution beyond binstall — Homebrew formula, mise/aqua registry entries — is downstream of both a public repository and CLOUD-278's manifest (a formula pins a checksum). Not attempted here; this is the record that the second half of this issue's title is outstanding.

Judgement call, recorded rather than assumed: README gains an Install section stating plainly that a GitHub token is required while the repository is private, keeping its existing status note verbatim. That reads CLOUD-205's "no install docs" as "do not imply public availability", not "do not build or document the private path" — the same decision asks the release machinery to keep running "so the flip is cheap when it comes" (CLOUD-65).

CLOUD-312 The engine is the pre-tool entry point; the shell guards retire behind it

Why

The pre-commit layer and CI are already adjudicated by the engine reading the committed authority. The agent tool-call layer is not: .claude/settings.json wires seven PreToolUse entries — gh-guard, ready-guard, issue-guard, run-shape-guard, memory-guard (twice, once per matcher), claim-guard — every one a mise run of a shell task carrying its own decision table, and batten hook appears in that file zero times.

Two implementations of one policy is two authorities for one fact, and the divergence is silent. A rule added to batten.toml does not reach the tool call, and a guard's table cannot be read from the config a reviewer reviews. crates/batten/src/hook.rs is the port of those guards and its own header describes the compatibility path as lasting "while they exist" — this issue is what ends that period.

It also makes the README's three-layer claim true. Today one third of it describes the design rather than the state.

The counts in this section are the pre-wiring state and are kept as the historical baseline, not as current fact. Re-counted 2026-08-20: .claude/settings.json carries thirteen registrations across six events, of which one reaches batten hook — the single PreToolUse entry. The remainder are SessionStart ×2, UserPromptSubmit ×2, Stop ×1, six further PreToolUse shell entries across five matchers, and PostToolUse ×1. CLOUD-713 owns the census that keeps that number honest; CLOUD-777 owns getting the engine onto every surface exactly once.

Mechanism

• Each PreToolUse entry invokes the engine with the harness adapter for the host. The decision comes from the mediated_call-scoped rows of the resolved config and from nowhere else.
• Every refusal a retiring guard renders is expressed as a config row with a required reason before that guard is removed. A guard is deleted only once its refusals are reproduced from config.
• Fail-open posture is preserved end to end: unreadable stdin, an unparseable payload, or a missing binary all resolve to allow, and the existing bypass variables keep working.

Ready

• Source of truth (§1). The committed batten.toml is the only table a mediated call is judged against. No decision table remains in mise-tasks/.
• Mechanism as a predicate (§2). Two gates, both exiting 0:
  1. a differential suite replays every payload fixture in the existing guard .bats suites through the engine and asserts the same decision and the same reason text;
  2. a source-level assertion fails if any PreToolUse entry in the settings file invokes a task that carries a decision table.
• Effect (§3). No new command surface: hook already exists and is already classified. What changes is who invokes it.
• Output & exit (§5). Every retiring guard's refusal keeps its reason text, which is what the differential suite asserts; the deny channel per host is the one Capabilities declares. Fail-open is preserved end to end — unreadable stdin, an unparseable payload, or a missing binary all resolve to allow — so no failure code Batten can produce is one a host reads as a deny.
• Commit / bump (§6). feat → patch until 0.1.0: below 0.1.0 release-plz bumps the patch whatever the type says.
• Test obligation (§7). The differential suite in §2, plus the settings-file assertion, both under mise run verify and CI. A guard is deleted only once its fixtures pass through the engine, so coverage never drops below what the retiring guard had.
• Blockers (§8). Superseded — see "Blockers, re-verified" below, which is the live list. Two rows were named here when this was written; both are resolved and their relations removed, and they are named there with their evidence. Repeating them here would be a blocker citation with no relation behind it, which ready-lint reports as blocker-cited-without-relation — measured on this row 2026-08-22, two violations, caused by removing the relations without editing this sentence. The live blockedBy relations are CLOUD-924 and CLOUD-925, per row rather than campaign-wide.

The gap is measured, not asserted

Counted against main: seven PreToolUse entries, zero invocations of the engine. The port itself is not the missing piece — hook.rs carries six harness adapters over a harness-blind core, its mediated_call matcher, and a per-host capability table — so what remains is the wiring and the config rows that make each retiring guard's refusal reproducible.

One clarification for whoever picks this up, because the neighbouring language invites the wrong move: the table hook must read is the mediated_call-scoped rows of batten.toml, not crates/batten/src/effect.rs. That module classifies Batten's own command surface for the §5 read-only allowlist, and its consumer is spec.rs. Two declared tables, two different objects; importing one into the other would put a classification of Batten's verbs in the path that judges a consumer's shell commands.

Done

main carries the engine as the pre-tool entry point with the differential suite green, no guard-local decision table remains, and CI is green on the merge commit landed by fast-forward.

---

The remaining inventory, re-counted 2026-08-22 against main (170c7c4)

This section is the campaign's operative content. Everything above it is history: the counts in Why are the pre-wiring baseline, and the ## Ready block's §8 is superseded by Blockers, re-verified below.

What has already changed under this row

• Registration is finished. CLAUDE_EVENTS carries eight events (hook.rs:1013, UserPromptSubmit added by CLOUD-777) and .claude/settings.json registers batten hook --harness claude-code matcherless on all eight. There is nothing left to register, and no new registration is planned by any row in this bundle. A row proposing one is proposing a second narrowing.
• The census moved in-process. batten doctor hooks (doctor.rs:225-344) computes the diagnosis from WiringFile and Wiring::registrations, reporting registrations / siblings / merged / merged_surfaces_read and eight stable reason ids — including hook-wiring-merged-registration, so a registration on a $HOME surface the repository does not own is visible. hooks-wiring-check.sh is now the thin caller holding this consumer's DECLARED table (:168-180).
• The door exists and has a worked example. [[hook.handler]] landed (CLOUD-898) and batten.toml:1912 dispatches mcp-attach-check through it. That guard is therefore already retired from this table — it is dispatched by batten hook, not registered beside it.

The thirteen remaining rows

One row per entry in hooks-wiring-check.sh's DECLARED table. Destination is the load-bearing column: durable policy goes to core/config, and a [[hook.handler]] is used only where an external program intentionally remains. Two of thirteen qualify; assuming every script becomes a handler would move eleven decision tables out of the committed authority and behind a dispatch.

#	Event / matcher	Command (lines)	Owner	Destination	Blocker & ordering
1	PreTool .*save_issue	mise-tasks/issue-search-guard.sh (93)	312	config — a receipt row over the search receipt	none; first in the board family
2	PreTool .*save_issue	mise-tasks/issue-read-guard.sh (117)	312	config — a receipt row with the recency bound facts::Sourced borrowed from it	none; after 1 (shares the matcher and the receipt store)
3	PreTool .*save_issue	mise-tasks/board-move-guard.sh (158)	312	config — a receipt row keyed on the issue key	none; after 2
4	PreTool .*(subscribe_pr_activity|send_later|create_trigger)	mise-tasks/connector-verb-guard.sh (174)	312	config — but the predicate is a tool-name suffix, and no rule kind selects on one today; [[verb]] names a shell program	blocked on CLOUD-924 — no rule kind keys on the tool a call names, and this guard matches by SUFFIX deliberately
5	PreTool ^mcp__	mise-tasks/connector-allow-guard.sh (88)	312	config — needs a connector-grant table in batten.toml; the grants live in .claude/settings.json today	blocked on CLOUD-924 (the selector), plus that grant table
6	PreTool Task	mise-tasks/fanout-guard.sh (158)	312	config — Field::Prompt exists, but [budget.<name>] is a file-set budget over globs, not a per-call ceiling	blocked on CLOUD-925 — [budget] counts a file set, so a per-call ceiling is inexpressible
7	PostTool .*save_issue|.*save_comment	mise-tasks/board-write-record.sh (329)	312	core — it derives a record from a tool response, which is exactly the capture bundle's first consumer	ordered after CLOUD-919; porting it first would build a second reader of the response
8	UserPromptSubmit	mise-tasks/mcp-allow-check.sh --session (415)	312	handler — reads settings files and MCP client logs, not the envelope; its sibling mcp-attach-check already went this way	none; the door is landed
9	Stop	mise-tasks/stop-guard.sh (318) + five gates (1,412)	892	config / core	CLOUD-892 owns it end to end
10	SessionStart	.claude/hooks/session-start.sh (295)	312	handler — it provisions a toolchain and preflights the container. There is no decision table in it to move; it is deliberately synchronous and deliberately loud on failure	none, but see the bound below
11	PreTool Bash	mise-tasks/run-shape-guard.sh (647)	821	config, partially — Field::RunInBackground landed, so the exemption predicate is expressible	CLOUD-613 for the heredoc-binding family; CLOUD-821 owns the row
12	Stop, merged $HOME	stop-hook-git-check.sh	605 / 893	out of repo — not ours to port	CLOUD-893 owns visibility, CLOUD-605 the identity conflict
13	SessionStart, merged $HOME	session-start-git-identity.sh	605 / 893	out of repo — same	as 12

Row 10 carries a bound the door does not give for free

[[hook.handler]] imposes a timeout_ms, and this script's whole reason for existing is that a cold mise install inside the MCP client's startup window took 24s. A bound tighter than the cold path turns a fail-open handler into the absence the hook was built to close. So its handler row declares a measured bound, and the migration records the cold measurement beside it — the same standard mcp-attach-check's timeout_ms = 2000 was held to.

Per row, the two obligations this issue has always carried

Unchanged in substance from Mechanism above, restated because the table needs them per row:

• Differential test. Every refusal the retiring script renders is reproduced from the committed authority before the script is deleted, proved by replaying that script's own .bats fixtures through the engine and asserting the same decision and the same reason text. A handler destination has the same obligation with the door in the path: the fixture goes through batten hook, and the reply is byte-compared.
• Exact deletion condition. The script, its DECLARED row, and its bats suite go in one change, and only once its fixtures pass through the engine — so coverage never drops below what the retiring guard had. A DECLARED row naming a deleted command already fails as wiring-declaration-stale, and a command with no row already fails as wiring-sibling-command, so both directions of the deletion are gated rather than reviewed.

Blockers, re-verified 2026-08-22 — this supersedes §8 above

• CLOUD-446 — cleared, Done. The claimed-key lookup it called unreachable from the mediated path is reachable: CLOUD-776 landed the agent-sourced fact channel, and claim-not-raced is its worked instance.
• CLOUD-461 — cleared, landed (In Review). The advisory channel is on main, and contract-drift retired with it. Its own release is not this row's precondition.
• New, per row rather than campaign-wide, and filed rather than deferred: rows 4 and 5 are blocked on CLOUD-924 (no rule kind keys on the tool a mediated call names); row 5 additionally needs a connector-grant table in batten.toml; row 6 is blocked on CLOUD-925 ([budget] counts a file set, so a per-call ceiling is inexpressible); row 7 is ordered after CLOUD-919. Nothing blocks rows 1, 2, 3, 8, 10.
• Two rows first named here as blockers are Done, and naming them would have been the defect this table gates against. CLOUD-684 (MCP allow rules naming labels host servers never register under) and CLOUD-734 (re-projecting the grants at SessionStart) are both closed. What row 5 actually lacks is a config surface, which is why CLOUD-924 exists and those two do not appear above.

Stating them per row is the correction: a single campaign-wide blockedBy is what let this row sit blocked on a capability that only one of its thirteen entries needed.

The end-state test

Three predicates, all decidable by machinery that exists:

1. Exactly one Batten registration per supported event, per harness — doctor hooks already fails hook-wiring-event-registered-n-times and hook-wiring-event-unregistered, and hook-wiring-matcher-narrows on any matcher at all.
2. No unmanaged sibling command — doctor hooks reports siblings == 0 and merged == 0, or every remainder is a DECLARED row naming a key that is still open. A row naming a closed key already fails, which is what keeps this from becoming a permanent waiver list.
3. Every remaining dispatched behaviour is declared in committed configuration and validated from it — each surviving program is a [[hook.handler]] row in batten.toml with a declared bound, and its behaviour is pinned by a differential case run through the door. Nothing reaches a hook surface that the committed authority does not name.

Done is the three above holding together, with main green: not "the scripts are gone", because a deleted script whose refusals nothing reproduces is a coverage loss wearing a retirement's clothes.

Blocked by an upstream yank, not by this diff

mise run verify refuses this branch at the semver step, and the cause is outside this PR. Recording it here rather than pushing at it.

What fails. cargo-semver-checks exits 101 — which the task correctly treats as "neither verdict" and reports as exit 2 rather than a pass. Its actual output:

error: failed to select a version for the requirement `bisync = "^0.3.0"`
  version 0.3.0 is yanked
  version 0.3.1 is yanked
location searched: crates.io index
required by package `gix-protocol v0.64.0`
    ... which satisfies dependency `gix-protocol = "^0.64.0"` of package `gix v0.86.0`
    ... which satisfies dependency `gix = "^0.86"` of package `batten`

Why it is not this PR's. The diff touches crates/batten/src/rules.rs, batten.toml, a bats suite and two generated schemas — no manifest and no lockfile. bisync is transitive: gix-protocol 0.64.0 ← gix 0.86 ← batten. Our committed Cargo.lock pins bisync 0.3.0 with a checksum, and cargo builds a locked tree containing a yanked version happily — which is why every build and every test run on this branch passes. cargo-semver-checks synthesises a scratch crate and runs an unlocked cargo update, which refuses yanked versions, so no rustdoc can be generated for either side of the comparison.

It is also not a flake: it reproduced identically twice (through the task, then invoking the tool directly), and the same dependency set passed semver when #711 landed a few hours ago. The yank happened in between.

The gate behaved correctly and should not be touched: it refused rather than reporting green over a comparison that never ran.

Proposed patch, deliberately not applied here

The upstream fix exists: gix-protocol 0.65.1 drops the bisync dependency entirely. Reaching it needs a gix bump, because gix 0.86 requires gix-protocol ^0.64.0 and a 0.x caret excludes 0.65.x. The first gix that pulls it is 0.87.1 (gix-protocol ^0.65.1).

I evaluated that bump on this branch and reverted it: it is not drop-in. gix 0.86 → 0.87 breaks the object-access code in crates/batten/src/git.rs:

• error[E0277]: the trait bound Proxy<Cache<Handle<Rc>>>: Find is not satisfied (several sites)
• five error[E0308] type mismatches, including around gix::objs::tree::EntryMode

So it is a real gix migration with its own verification surface, not a lockfile bump — and folding it into a policy-gate PR would be widening. It wants its own change:

1. Cargo.toml: gix = "0.87", then cargo update -p gix --precise 0.87.1 (pulls ~20 gix-* crates forward).
2. Repair git.rs for the Find trait-bound and EntryMode changes.
3. Full verify, since git.rs underpins the ratchet, the epoch and the landing checks.

Until that lands, semver blocks every PR in this repo, not just this one.

Correct the "two ... subsumed" claim.

Line 1976-1977 states: "The two that did have successors are subsumed below." The actual ledger in crates/batten/tests/ratchet.rs claims one case as subsumed and the other as changed, not both as subsumed. Update the wording so the comment matches the ledger it describes.

Correction, and the deadlock

Two things wrong in my comment above. Correcting both, because one of them is a factual claim about this codebase that would send the next reader down a migration that isn't needed.

1. There is no git.rs API breakage. I reported gix 0.86 → 0.87 as breaking with a Find trait-bound failure and five E0308s. That was a misread: the errors carried a note I filtered out of my own log —

note: there are multiple different versions of crate `gix_object` in the dependency graph

It was version skew, not an API change. gix 0.87.1 requires gix-object ^0.64.1 and gix-diff ^0.67.1, while our workspace pinned gix-diff = "0.66" (which wants gix-object ^0.63). Two gix-object majors in one graph, so gix_diff::tree's parameter types and gix's re-exported types stopped unifying. Bumping both together is the whole fix:

gix      = { version = "0.87", … }   # was 0.86
gix-diff = { version = "0.67", … }   # was 0.66

mise run lint:clippy is clean on that, with no source changes. My "7 sites in git.rs" figure counted symptoms of the skew, not work to do.

2. The fix cannot land through verify, and that is the actual blocker. cargo-semver-checks builds its baseline from origin/main, and the failing resolve is now unambiguously on that side:

... which satisfies dependency `gix = "^0.86"` of package `batten v0.0.120
    (/home/user/batten/target/semver-checks/git-origin_main/7eef4ad…/crates/batten)`

origin/main still requires gix 0.86 → gix-protocol 0.64.0 → yanked bisync ^0.3.0. So:

• land runs verify, which runs semver;
• semver resolves origin/main unlocked, which fails on the yank;
• therefore nothing can land — including the two-line change that repairs main.

My branch's own side is fine. No edit I can make here changes the baseline.

What this needs, and it is not mine to choose

The bump is ready and verified on this branch. Getting it onto main needs one of:

1. The yank being lifted upstream, or a gix-protocol patch release for the 0.64.x line that drops bisync — outside this repo.
2. A deliberate, one-time route past semver for the commit that fixes it. That is a decision about the gate's authority, not a workaround I should take on my own initiative.
3. semver.sh distinguishing "the baseline is unbuildable" from "the delta is incompatible." Arguably the real defect: the gate's object is this branch's API delta, and a baseline that cannot resolve is not a verdict about this branch. Today both collapse to exit 2. That is a genuine gate-design question and wants its own issue rather than an ad-hoc edit here.

Until one of those happens, verify refuses every branch in this repository, not just this one. Flagging rather than forcing.

Closing without merging, and parking the work rather than discarding it.

What happens to each commit

• 66d4bfe — dropped. main already carries both bumps in d77371a ("gix 0.87, because every version of bisync was yanked under us"), verified as an ancestor of origin/main today. The commit is a no-op; there is nothing to preserve.

• f39265e — preserved, then parked. GitHub keeps refs/pull/713/head permanently, so the design, the ledger text and the four test cases stay fetchable after this branch moves:

  git fetch origin refs/pull/713/head
  

  Verified resolving to 66d4bfe (with f39265e as its parent) after the branch reset.

Why it is re-implemented rather than rebased

f39265e was written against a crates/batten/src/rules.rs that #712 has since superseded, not merely conflicted with. On main today conserve_case_names returns fully_mapped and retirement_blockers consumes it to skip fully-mapped paths (CLOUD-1050's mapped-successor arm) — a seam that did not exist when this branch was written, and a cleaner one. Rebasing would fight it; the arm is re-implemented against it instead.

Two defects in this branch are also not carried forward:

1. It cites CLOUD-1052 in code comments, batten.toml and the commit body. CLOUD-1052 is a real, Done issue titled "Measure full rule-document injections from Claude transcripts" — unrelated to ratchets. A false citation baked into source.
2. An earlier test pass asserted on stdout reason strings; the suite's convention is pointers (path:line), and reason ids do not appear in plain output.

Where the work continues

CLOUD-1080 — "conserves has no arm for a WITHDRAWAL: all three name a successor, so a deletion whose subject is gone can only pass by lying or by a waiver config-lint refuses" — carries the design, the §7 obligation (including the discriminating live-subject case asserted at the arm's own line) and the container-setup ledger. It is filed relatedTo CLOUD-1050, CLOUD-908, CLOUD-312 and CLOUD-1037, the last because a fourth arm reaches two readers: rules.rs and mise-tasks/replay.sh, whose arm list is the literal carried subsumed changed. Adding a token to one and not the other re-forks exactly the grammar CLOUD-1037 exists to reconcile.
