docs(memory): a fan-out cannot reach Done, so the dispatch brief must schedule that leg

[wenzowski]

What this is

CLOUD-839 dispatched five bundles. Their workflow contract — repeated verbatim in all five prompts — said "carry the lifecycle to landed-and-verified". That is In Review, and every agent hit it exactly.

Sixteen of seventeen spine rows then sat In Review across three releases. A board-wide census run today found the problem is wider than the campaign: 46 rows are In Review on work a v* tag has already shipped.

Why no agent could have done otherwise

Neither actor in a fan-out can perform the In Review → Done move:

• The implementer cannot. The tag postdates its merge by a release cycle. Bundle A landed 01:38; v0.0.103 was cut 02:44.
• CI cannot. release-plz.yml's promotion step is read-only by its own comment: "Performing the move needs a Linear token that does not exist yet; printing the list needs nothing." It prints what would move into the run summary. Nothing reads it.

Both memories were already right about the model — board-states says the last leg is yours, and agent-fanout's implementer contract correctly ends at In Review. What neither said is the dispatcher's consequence: a fan-out that lands N rows leaves N rows In Review by construction, so the brief must schedule the post-release pass or nobody will.

Same shape as CLOUD-825: a mechanism that decides nothing because it has no invoker.

Also recorded

A defect met while running the sweep: released blocks when backgrounded. It picks its payload source with [ -t 0 ], which is false for a task-runner or backgrounded call whether or not anything was piped — so a bare invocation falls through to cat and hangs on a stdin nobody closes. Measured: ~15 minutes before it was killed. </dev/null selects the refs-only form.

The memory also carries how to run the pass (released → conjunction with graph-check → done-check) and the warning that shipping a ref is necessary, not sufficient — each row's own Acceptance gets read against the released tree first, because CLOUD-807 was once Done with none of its acceptance met.

Done so far under this dispatch

Five rows promoted with per-row acceptance verified against the released tree: CLOUD-831, 832, 833, 836, 837 — bundle A's spine. Gate verdict was 5 to move, 0 left alone, no HELD, no REFUSED, exit 0. 41 candidates remain.

Note on the diff

This branch briefly also carried a fuzz/Cargo.lock resync (it sat at 0.0.101 against a 0.0.103 workspace). Rebasing onto current main dropped it as already upstream — b4ea891 landed the same regeneration first. The branch is now the single memory commit.

CLOUD-839 Fleet dispatch: the Rego-capability spine — five bundles, seven PRs, sized by the landing lease rather than by worker count

Sixteen rows, groomed to Ready and verified as a set on 2026-08-21. The bundles and prompts live here rather than in a chat that dies with its container, per CLOUD-607's precedent and CLOUD-784's shape.

These are the capabilities the bash-retirement campaign needs before a single one of the 79 gate-described mise-tasks/ programs or 11 hook bodies can move. The migration itself is a separate, much larger campaign and is not dispatched here.

The frontier is computed, not asserted

mise run graph-check over all sixteen payloads, 2026-08-21:

CLOUD-647 excluded (blocked-by CLOUD-833 CLOUD-837)
CLOUD-832 excluded (blocked-by CLOUD-831)

wip 0
frontier CLOUD-743 CLOUD-747 CLOUD-777 CLOUD-807
frontier CLOUD-820 CLOUD-822 CLOUD-824 CLOUD-831 CLOUD-838

Zero violations. The three residual exit-2 lines are status-claim-unjudgeable for claims about ids outside the piped closure (743→740, 824→62, 835→15) — a property of the chosen closure, not of the board, and the other half of CLOUD-838's finding.

Two edges were added the same day to make this graph honest, both previously prose:

• CLOUD-833 blockedBy CLOUD-837 — 833's §2 says it "evaluates every module in the bundle", and 837 measured that Engine::new() sits inside policy::load's loop. Building bundle evaluation on N isolated engines means building it twice.
• CLOUD-834 blockedBy CLOUD-833 — both re-key fact_class at rules.rs:692 from const fn (RuleKind) to a function of kind and scope. Two branches doing that independently is a semantic conflict, not a mechanical one.

CLOUD-129 was closed rather than bundled. Its Lands as is its own body, so it lands no commit — leaving it Todo would have blocked 832, 833, 836 and 837 on a board move nobody was scheduled to make. Its adopt table now carries the corrected verdicts and it is Done, which is why it is absent from the graph above.

The constraint that sizes this: landing is a fleet-wide lease

land-lock's own header: "hold a rolling fleet-wide landing lease, so exactly one branch at a time spends CI on a landing attempt." Before it existed, the measured cost was 243 refusals against 5 merges — a ~2% success rate per attempt (CLOUD-393, CLOUD-399).

So the scheduling variable is PR count, not agent count. One land lap is rebase → verify → push → ci-wait → /fast-forward, and the ci job's own budget comment records p95 = 701s. Call a lap ~15–20 minutes, strictly serialized:

PRs	serialized landing
7	~2 hours
15	~4.5 hours
30	~9 hours

And each land invalidates every other in-flight branch, which must then rebase and re-verify — so the cost is worse than linear in branch count. Past roughly eight PRs, another worker adds landing time without removing work time. That is why this is five agents and not thirty, and it is arithmetic rather than caution.

The critical path compounds it: 831 → 832 → 837 → 833 → {647, 834} is five levels deep. Dispatched one row per PR that is five serialized lands before the last capability exists. Bundle A collapses all five into one branch and one land — the single biggest lever in this plan, and the reason A is six rows rather than two.

One PR carrying many rows is the intended shape, not a deviation: CLOUD-661 retired the one-PR-per-ticket prescription for exactly this case, and CLOUD-502 (which worried the WIP cap could not represent it) is Canceled.

The bundles

Five agents, seven PRs, sixteen rows. All five can start at once. A bundle with more than one row lands them in the order given, on one branch, in one draft PR unless noted.

#	Chain	File domain	PR shape
A policy-spine	831 → 832 → 837 → 833 → 836 → 647	policy.rs, rules.rs (scopes/fact_class), lint.rs, Cargo.toml, batten.toml, schema/*, new policy/*.rego, tests/policy_modules.rs	1 PR — the whole critical path in one land
B surface-hooks	(777 + 824) → 835 → 834	hook.rs, doctor.rs, git.rs, surface.rs, spec.rs, completions/, man/, .claude/settings.json, .claude/hooks/, hooks-wiring-check, facts.rs	3 PRs — 777+824 now, 835 after A, 834 after A and C
C crate-posture	743 → 747	clippy.toml (new), Cargo.toml lints, .claude/rules/rust.md, capture.rs, exec.rs, nine #[expect] sites, perf-assert	1 PR
D retirement-permit	807	rules.rs (ratchet retires_with), schema/*, batten.toml (waiver deleted), 141 tests/*.bats # subject: headers, new tests/ratchet-retirement.bats	1 PR
E board-gates	838 → 820 → 822	mise-tasks/graph-check, mise-tasks/claim-check, run-shape-guard, batten.toml, bats	1 PR

Why B owns three rows on two different surfaces. 777 adds a doctor hooks sub-verb and 835 adds policy test; both regenerate completions/batten.{bash,fish,zsh} and a man/batten-*.1 page, byte-diffed by derived-check. Putting both in one agent's branch history turns a cross-branch regeneration conflict into two sequential commits — the conflict is designed out rather than resolved. 834 joins them because hook.rs is the same file 777 and 824 rewrite.

Why D is alone. 807 inserts a header line at the top of all 141 bats suites. That is broad and shallow: it collides with another branch only if that branch also edits a file's first lines, which E's three suites do not.

The conflict register

Not zero-conflict, and deliberately so — these are the ones worth knowing about in advance. Everything else is ordinary.

Unresolvable by hand — regenerate, never merge:

1. schema/batten.schema.json (1,654 lines) and schema/batten.local.schema.json (756) are regenerated by A (832's row keys, 833's widened scope) and D (807's retires_with). Whichever rebases second runs mise run fix and regenerates; merging two regenerated schemas silently produces a file neither branch would have produced.
2. completions/* and man/* — B only. Designed out, see above.

Semantic, needs re-derivation:

3. rules.rs:692 fact_class — A (833: kind × scope) then B (834: + the cost dimension). Now a real blockedBy, so B's third PR rebases onto a landed A rather than racing it.

Mechanical — keep both:

4. rules.rs ratchet kind (D) is a different region from scopes/fact_class (A).
5. hook.rs — A touches only the ~20-line protected extension at :1918-1940; B owns the rest. Expect collisions in the #[cfg(test)] tail and keep both sides.
6. batten.toml — A (831's command row, 832's severity keys, 836's [policy]), D (waiver deletion at :1473), E (822's shape row). Different regions.
7. Cargo.toml — A (regorus features, and the :150 count comment which says 45 and measures 56), C ([workspace.lints.clippy], tokio). Different tables.
8. tests/*.bats — D inserts at file top across 141 files; E edits three bodies.

Land order

The lease serializes anyway; this is about not blocking each other.

1. A and B-PR1 race for the lease — both unblocked, and each unblocks work downstream.
2. C, D, E in whatever order they are ready. C unblocks B-PR3.
3. B-PR2 (835) after A lands.
4. B-PR3 (834) last — it needs A, B-PR1 and C.

If you want to spend more than five workers

The one split that buys time rather than costing it: A into A1 (831 → 832 → 837) and A2 (833 → 836 → 647) on stacked branches — A2 branches off A1 rather than main, both work in parallel, A1 lands first and A2 rebases. That is +1 PR (~20 min of lease) to roughly halve the longest bundle. Six agents, eight PRs.

Beyond that, more agents means more PRs means more serialized landing. The capacity is better spent inside a bundle — a second pair of eyes on A's policy.rs restructure, or on D's 141-file sweep — than on a ninth branch.

Dispatch prompts

Five self-contained blocks — one paste per session, nothing to prepend. An earlier revision split these into a shared workflow-contract block plus a per-bundle block; a human pasting one quoted block would silently drop the contract, which is how CLOUD-728's five bundles came up unsupervised. The contract is now repeated verbatim inside each, and the repetition is the point.

A — the policy spine

You are bundle A of the CLOUD-839 fleet dispatch in the Batten repo. Read CLOUD-839 first:
it carries the computed frontier, the land order and the cross-bundle conflict register.
Four sibling agents (B, C, D, E) are working other bundles concurrently against the same main.

YOUR CHAIN - one branch, one draft PR, landed in this order:
  CLOUD-831 -> 832 -> 837 -> 833 -> 836 -> 647

You are the critical path: this chain is five levels deep on the board and bundle B's second
and third PRs both wait on it. One row per PR would be five serialized lands against a
fleet-wide lease. Landing it as ONE PR is the point of this bundle. Split only if a row
genuinely will not land, and say so on that row if you do.

The order is dependency, not taste:
- 831 gates the IO-free feature pin the whole surface rests on. Its section 2(b) predicate
  walks the resolved closure FROM THE REGORUS NODE, not batten's - the wider spelling denies
  on main forever, measured on the row with a firing-rate replay. Severity is deny. While in
  Cargo.toml, fix :150's package count: it says 45 and resolves 56.
- 832 gives predicates their own ids (Conftest's `violation` shape alongside the existing
  string `deny` set) so severity, [[waiver]] and mutant stop keying off the registering row.
  The bare-string path stays green - this is additive.
- 837 moves Engine::new() out of policy::load's loop so a bundle is one composed engine, not
  N isolated ones. Also fix DENY_QUERY: pin the rule names (deny, violation, rules), not the
  package - which is what its own comment claims and the constant contradicts.
- 833 admits RuleKind::Policy to RuleScope::Tree and re-keys fact_class on kind AND scope.
  Every enabled bundle root joins the `protected` set: a folder must not be less protected
  than a named file was.
- 836 lands vendored preset bundles via include_str!. Generic only - no consumer's gate ids
  inside crates/batten (non-negotiable rule 1).
- 647 is the whole-set analysis; it needs both 833's surface and 837's engine.

AUTHORITY ON BUNDLE SHAPE is CLOUD-129 (Done). Its corrected adopt table: a bundle is a
FOLDER THE ONE COMMITTED AUTHORITY ENABLES - never a glob, never an upward walk, never a
remote fetch - and a vendored preset is content the authority enables, not a second
authority. Section 8's test is its invariant (raise-only), which deny-only modules satisfy
by construction.

CROSS-BUNDLE CONFLICT: you and bundle D both regenerate schema/batten.schema.json and
schema/batten.local.schema.json. If D lands while you are in flight, rebase and re-run
`mise run fix` to REGENERATE - never merge the generated diff; two merged regenerations
produce a file neither branch would have produced. You also touch ~20 lines of hook.rs (the
`protected` extension at :1918-1940); bundle B owns the rest of that file, so expect
collisions in its #[cfg(test)] tail and keep both sides.

WORKFLOW CONTRACT (AGENTS.md is authoritative; this is the summary):
- Claim by hand BEFORE writing code: `mise run claim-check`, and assign yourself. The
  automation fires on the PR event, the end of the work, so waiting for it reserves nothing.
- `git fetch origin main`, short-lived branch, never author on main.
- Commit early and often. You are pre-authorized to commit and push without asking.
- Run the full `mise run verify` after EVERY commit. Local execution is free; a CI run is
  metered and the landing lease is fleet-wide.
- Open the PR as a DRAFT immediately (`gh pr create --draft`). CI does not run on drafts, so
  you iterate at zero CI cost.
- When the chain is complete: `mise run linear-check`, then `mise run land` backgrounded. Do
  NOT ready by hand - land readies after its push. Do NOT wrap land in bespoke retry or
  pre-check logic; main advancing under you is that loop working.
- Background anything that can exceed ~2 minutes; a foreground command is killed at ~2 min.
- Move the Linear row as you move the work. Carry the lifecycle to landed-and-verified
  without stopping to report and wait. Stop only for a rebase conflict needing a human
  decision, a gate that fails ambiguously, or scope outside this bundle.

B — the hook surface, the two new verbs, the projection

You are bundle B of the CLOUD-839 fleet dispatch in the Batten repo. Read CLOUD-839 first:
it carries the computed frontier, the land order and the cross-bundle conflict register.
Four sibling agents (A, C, D, E) are working other bundles concurrently against the same main.

YOUR CHAIN - three PRs, in this order:
  PR1: CLOUD-777 + CLOUD-824   (unblocked, start now)
  PR2: CLOUD-835               (after bundle A has landed)
  PR3: CLOUD-834               (last - after A, your PR1, and bundle C)

PR1 - the hook surface, both rows on one branch:
- 777 adds Event::UserPromptSubmit, APPENDED NEVER INSERTED (semver reads a reordered
  variant as enum_no_repr_variant_discriminant_changed), grows CLAUDE_EVENTS to eight, gives
  every event an explicit `adjudicated` arm carrying either a decision or a stated no-op (no
  fall-through), and moves the wiring check out of ~300 lines of bash into a
  `batten doctor hooks` sub-verb. House style section 2 already specifies doctor as nesting
  focused sub-diagnostics, so this is the specified shape, not a new idea.
- 824 DELETES .claude/hooks/batten-hook.sh and moves root resolution into the binary through
  git::repo_root. All seven claude-code registrations then invoke `batten hook --harness
  claude-code` directly, as the other four harnesses already do. The launcher's `cd` uses
  --show-toplevel, which is the worktree's root, not the repository's - so in a linked
  worktree load_policy finds no batten.toml and allows every mediated call silently. The
  pinned regression is the linked-worktree fixture, red on main today.

PR2 - 835 adds `batten policy test`: Rego test_ rules evaluated in-process by the already
embedded regorus, over fixtures the row declares. The coverage feature is already pinned.

PR3 - 834 projects the resolved fact set into the policy input. Its keys are facts.rs's Fact
variants, asserted by exhaustive match - never a second fact vocabulary re-derived in JSON.
A call no policy row selects for must resolve NOTHING, asserted by a spawn/read counter, not
by timing.

CROSS-BUNDLE CONFLICT: you are the ONLY branch regenerating completions/batten.{bash,fish,zsh}
and man/batten-*.1, and that is deliberate - both new verbs (777's `doctor hooks`, 835's
`policy test`) live in your branch history so the regeneration conflict never crosses
branches. Keep it that way. You own hook.rs; bundle A touches ~20 lines of it (the
`protected` extension at :1918-1940), so expect collisions in the #[cfg(test)] tail and keep
both sides. 834 and bundle A's 833 both re-key fact_class at rules.rs:692 - that is a real
blockedBy on the board, so PR3 rebases onto a landed A rather than racing it.

WORKFLOW CONTRACT (AGENTS.md is authoritative; this is the summary):
- Claim by hand BEFORE writing code: `mise run claim-check`, and assign yourself. The
  automation fires on the PR event, the end of the work, so waiting for it reserves nothing.
- `git fetch origin main`, short-lived branch, never author on main.
- Commit early and often. You are pre-authorized to commit and push without asking.
- Run the full `mise run verify` after EVERY commit. Local execution is free; a CI run is
  metered and the landing lease is fleet-wide.
- Open each PR as a DRAFT immediately (`gh pr create --draft`). CI does not run on drafts, so
  you iterate at zero CI cost.
- When a PR's chain is complete: `mise run linear-check`, then `mise run land` backgrounded.
  Do NOT ready by hand - land readies after its push. Do NOT wrap land in bespoke retry or
  pre-check logic; main advancing under you is that loop working.
- Background anything that can exceed ~2 minutes; a foreground command is killed at ~2 min.
- Move the Linear row as you move the work. Carry the lifecycle to landed-and-verified
  without stopping to report and wait. Stop only for a rebase conflict needing a human
  decision, a gate that fails ambiguously, or scope outside this bundle.

C — the spawn gate, then the concurrency posture

You are bundle C of the CLOUD-839 fleet dispatch in the Batten repo. Read CLOUD-839 first:
it carries the computed frontier, the land order and the cross-bundle conflict register.
Four sibling agents (A, B, D, E) are working other bundles concurrently against the same main.

YOUR CHAIN - one branch, one draft PR, landed in this order:
  CLOUD-743 -> CLOUD-747

743 first, because 747's acceptance says the spawn-census gate carries the tokio::signal ban,
so that gate has to exist before 747 can extend it.

- 743 adds clippy.toml at the workspace root with one disallowed-types entry for
  std::process::Command, and sets the lint to DENY IN [workspace.lints.clippy] ITSELF - not
  left at warn and promoted by -D warnings. That distinction is the whole gate: CLOUD-822
  measured `mise exec -- cargo clippy -p batten --all-targets`, the escape no-bare-cargo's
  own refusal text recommends, missing 10 expect_used errors because it omits -D warnings.
  A gate whose verdict depends on which sanctioned invocation ran is not a gate.
  Each verdict lives in the #[expect] on the line it describes - no census table anywhere.
  #[expect] rather than #[allow] so a DELETED spawn with a stale annotation is also red.
  RE-DERIVE the nine-site census at implementation time rather than trusting the row's table;
  it was measured 2026-08-20 and git.rs has moved since. The discriminator case is load-
  bearing: surface.rs:34 is `use clap::{Arg, ArgAction, Command};` and that module's four
  Command sites must need NO annotation. A grep counted 14 and ast-grep would count 11;
  name resolution gets 9, which is why the gate is clippy and not a string scan.
- 747 then writes the concurrency posture into .claude/rules/rust.md as one authority, and
  rewrites capture.rs:223 and exec.rs:109 to their surviving reasons (both currently argue
  partly on dependency cost, a premise that dies when reqwest lands). Profile FIRST. Where a
  verdict is "stays because nothing measured asks otherwise", say so in those words - that is
  what stops the next person re-running the experiment.

CROSS-BUNDLE CONFLICT: you and bundle A both touch Cargo.toml, but different tables - yours
is [workspace.lints.clippy] and the tokio entry, theirs is the regorus feature list. Expect
an adjacent-line rebase, nothing semantic. You are the only branch in .claude/rules/rust.md.

WORKFLOW CONTRACT (AGENTS.md is authoritative; this is the summary):
- Claim by hand BEFORE writing code: `mise run claim-check`, and assign yourself. The
  automation fires on the PR event, the end of the work, so waiting for it reserves nothing.
- `git fetch origin main`, short-lived branch, never author on main.

  without stopping to report and wait. Stop only for a rebase conflict needing a human
  decision, a gate that fails ambiguously, or scope outside this bundle.

D — the retirement permit

You are bundle D of the CLOUD-839 fleet dispatch in the Batten repo. Read CLOUD-839 first:
it carries the computed frontier, the land order and the cross-bundle conflict register.
Four sibling agents (A, B, C, E) are working other bundles concurrently against the same main.

YOUR ROW - one branch, one draft PR:
  CLOUD-807

This one has a deadline. The [[waiver]] over bats-tests-not-deleted at batten.toml:1473
expires 2026-09-13 and is BLANKET - it carries only `rule` and `reason`, no path key - so a
deny-severity ratchet over the entire test corpus is switched off repo-wide right now. When
it lapses, every in-flight bash retirement blocks.

Land three things:
- `retires_with` on the ratchet rule kind: a decrease is admitted IFF, in the same change,
  every path named by the affected suites' declared subject is deleted. Every other decrease
  still denies at severity = deny. Decidable from two trees - no network, no judgement.
- A `# subject:` header on all 141 tests/*.bats. The subject must be DECLARED, never inferred
  from the filename: measured, 19 of 141 have no same-named mise-tasks/ program and all 19
  are legitimate (verify.bats and cross-check.bats cover mise.toml tasks, git-hook.bats
  covers .claude/hooks/git-hook, and 9 more are aspect suites). A filename heuristic would
  either block real retirements or admit real deletions. That header also pays for itself
  twice - it is the attribution key CLOUD-365 needs for per-subject runtime.
- DELETE the waiver row. Not renew it. Net effect is a stronger ratchet than today.

The negative case is the one a blanket waiver cannot express and the one that makes this real:
cases deleted while the subject STILL EXISTS must deny. A test asserting only the happy path
would pass on a rule that admits everything, which is the current state.

CROSS-BUNDLE CONFLICT: you and bundle A both regenerate schema/batten.schema.json and
schema/batten.local.schema.json. Whichever rebases second runs `mise run fix` to REGENERATE -
never merge the generated diff; two merged regenerations produce a file neither branch would
have produced. Your rules.rs work is the ratchet kind, a different region from A's scopes/
fact_class. Your bats change inserts at the TOP of 141 files; bundle E edits the bodies of
three suites, so collisions there should be near zero.

WORKFLOW CONTRACT (AGENTS.md is authoritative; this is the summary):
- Claim by hand BEFORE writing code: `mise run claim-check`, and assign yourself. The
  automation fires on the PR event, the end of the work, so waiting for it reserves nothing.
- `git fetch origin main`, short-lived branch, never author on main.
- Commit early and often. You are pre-authorized to commit and push without asking.
- Run the full `mise run verify` after EVERY commit. Local execution is free; a CI run is
  metered and the landing lease is fleet-wide.
- Open the PR as a DRAFT immediately (`gh pr create --draft`). CI does not run on drafts, so
  you iterate at zero CI cost.
- When complete: `mise run linear-check`, then `mise run land` backgrounded. Do NOT ready by
  hand - land readies after its push. Do NOT wrap land in bespoke retry or pre-check logic;
  main advancing under you is that loop working.
- Background anything that can exceed ~2 minutes; a foreground command is killed at ~2 min.
- Move the Linear row as you move the work. Carry the lifecycle to landed-and-verified
  without stopping to report and wait. Stop only for a rebase conflict needing a human
  decision, a gate that fails ambiguously, or scope outside this bundle.

E — three board gates

You are bundle E of the CLOUD-839 fleet dispatch in the Batten repo. Read CLOUD-839 first:
it carries the computed frontier, the land order and the cross-bundle conflict register.
Four sibling agents (A, B, C, D) are working other bundles concurrently against the same main.

YOUR CHAIN - one branch, one draft PR, landed in this order:
  CLOUD-838 -> CLOUD-820 -> CLOUD-822

- 838 gives graph-check's status-claim scanner an anti-vacuity arm. Its vocabulary is derived
  from the PIPED SET's own occupied statuses (graph-check:239), so a claim naming a column no
  piped issue currently occupies is not judged, not reported unjudgeable - it silently never
  matches. That inverts the predicate's purpose: the claims most likely to be stale are claims
  that a row LEFT a column. Measured on CLOUD-743, whose body carries both "CLOUD-740 is now
  Canceled" (false) and its own correction "CLOUD-740 is Todo, not Canceled" (true) - the gate
  matched the correction, passed, and was blind to the false claim beside it. Mirror the
  unjudgeable-milestone arm the same file already has for CLOUD-695: report
  status-claim-unscannable at EXIT 2, naming the two ids and the token, never the prose.
- 820 makes a missing read receipt a REFUSAL in claim-check rather than a silent fall-through
  to the updatedAt-versus-stamp clock CLOUD-615 replaced. claim-check already takes exactly
  this posture three lines above for the session stamp - this makes the two agree. Delete the
  clock fallback rather than leaving it as dead code; it is the comparison CLOUD-597 and
  CLOUD-615 each proved wrong in one direction, and leaving it invites a future reader to
  restore it as the "lenient" branch.
- 822 refuses a mediated `cargo` invocation that is a weaker form of a declared task's argv,
  naming the task that should have run. Derive the mapping from mise.toml - it already holds
  the real command lines - never restate it. A subcommand no task wraps is a genuine one-off
  and is untouched: the refusal is about SUBSTITUTION, not about the escape existing.

Each of the three carries a MUTANT directive: a refusal demoted to a note must be a mutation
the suite provably catches. Without it the arm is visible in the output and invisible to the
exit code, which is the reading that let 174 unmilestoned rows accumulate.

CROSS-BUNDLE CONFLICT: your bats work edits the bodies of three suites; bundle D inserts a
header line at the TOP of all 141, so collisions should be near zero. 822 adds a shape row to
batten.toml, which bundles A and D also touch in different regions.

WORKFLOW CONTRACT (AGENTS.md is authoritative; this is the summary):
- Claim by hand BEFORE writing code: `mise run claim-check`, and assign yourself. The
  automation fires on the PR event, the end of the work, so waiting for it reserves nothing.
- `git fetch origin main`, short-lived branch, never author on main.
- Commit early and often. You are pre-authorized to commit and push without asking.
- Run the full `mise run verify` after EVERY commit. Local execution is free; a CI run is
  metered and the landing lease is fleet-wide.
- Open the PR as a DRAFT immediately (`gh pr create --draft`). CI does not run on drafts, so
  you iterate at zero CI cost.
- When the chain is complete: `mise run linear-check`, then `mise run land` backgrounded. Do
  NOT ready by hand - land readies after its push. Do NOT wrap land in bespoke retry or
  pre-check logic; main advancing under you is that loop working.
- Background anything that can exceed ~2 minutes; a foreground command is killed at ~2 min.
- Move the Linear row as you move the work. Carry the lifecycle to landed-and-verified
  without stopping to report and wait. Stop only for a rebase conflict needing a human
  decision, a gate that fails ambiguously, or scope outside this bundle.

Dispatched by hand

Re-measured 2026-08-21 at dispatch time, once: create_session appears in the calling session's own tool surface and mcp-allow-check passed on the same turn, so the refusal was worth one probe rather than an assumption. It returned MCP tool call requires approval — byte-identical to the recorded failure, a day later. Not retried, per CLOUD-784's own instruction that re-measuring this is the loop the milestone exists to stop; one probe discharges "has it changed?", a second would be the loop.

create_session is refused in this environment and that is settled, not a workaround to re-litigate: CLOUD-734 is Done and records the measurement (the host's generated session config sets it to always_ask and editing it mid-session does nothing), with CLOUD-731 and CLOUD-784 as the precedents. A human opens five sessions and pastes the prompts above. Confirm each session's permission mode in the UI — get_session is unavailable, so no agent can confirm it, and CLOUD-728 measured five bundles coming up in the wrong mode and running to landed unwatched.

This row's own lifecycle

CLOUD-735: a dispatch record opens no PR and lands no commit, so both gates out of In Progress are unreachable by construction. Leave this in Todo and close it by hand once the bundles are away rather than pulling it and stranding it.

Refinement — Ready (2026-08-21)

Refinement gate: Definition of Ready & Done. This body carries only specializations.

• Source of truth (§1). The board itself. Every ordering claim above is a blockedBy relation, and the frontier is graph-check's output rather than a hand-derived list — if this row and the board disagree, the board is right and this row is stale. The two edges added today exist so the queue refuses a wrong order rather than an agent remembering it.
• Computable predicate (§2). mise run graph-check over the sixteen payloads reports no violations and prints the frontier quoted above. Run 2026-08-21, quoted verbatim. Each row also passes mise run ready-lint at exit 0 independently.
• Effect (§3). free — a tracker record. Nothing is resolved, built or spawned.
• Generated artifacts (§4). None.
• Output / exit (§5). No command surface is touched.
• Commit / bump (§6). none — this row lands no commit.
• Test obligation (§7). None of its own; each bundle carries its own §7. The claims here that could be wrong are the frontier and the conflict register, and re-running graph-check falsifies the first.
• Blockers (§8). None.

📝 Walkthrough

Walkthrough

The workflow guidance defines the dispatcher-owned Done transition. Implementers stop at In Review with the pull request attached. CI and release completion do not transition issues to Done. Dispatches schedule a post-release pass. The release closure procedure covers reference discovery, payload reconstruction, graph and Done validation, acceptance checks, and /dev/null stdin redirection for mise run released refs-only mode.

Merge Risk: 🔵 Low · up to 78503

The PR adds dispatch guidance for fan-out release closure, but the documented handoff into released and done-check remains incomplete; operators could select the refs-only path or run board-payloads without the required transcript and skip validation, leaving rows unclosed. This is a bounded documentation and integration risk, so the PR is mergeable with explicit owner follow-up.

🚥 Pre-merge checks | ✅ 5

✅ Passed checks (5 passed)

Check name	Status	Explanation
Title check	✅ Passed	The title clearly identifies the main documentation change: dispatch briefs must schedule the post-release Done transition for fan-out work.
Description check	✅ Passed	The description directly explains the documented workflow gap, the released-pass procedure, the stdin defect, and the related CLOUD-839 results.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 0 files. (1 skipped: 1 unsupported.)
Linked Issues check	✅ Passed	Check skipped because no linked issues were found for this pull request.

Document the release-closure payload handoff.

released invokes graph-check by path when it receives payloads on stdin. Its </dev/null form is refs-only and skips that check. Document how board-payloads output reaches released and how the Done payload reaches done-check. Require a readable .claude/.transcript.jsonl before board-payloads; linear-check does not read the transcript.
