Retires part of this session's 39 mise-tasks/** programs onto the policy
engine, and lands the engine capability those ports depend on. One branch, one
PR; a sibling session holds the other 44 programs and lands first.

What this closes

Closes CLOUD-1709

Only CLOUD-1709. The other six keys are In Progress and are NOT closed by
this PR — closing a key whose acceptance is unmet moves the row on a claim the
tree does not support, which is the board-state defect landed-check exists to
catch. They are named below with what actually landed against each.

CLOUD-1709 — complete

.github/workflows/** is counted. Two ratchet rows, because a ratchet pattern
is a literal substring with no regex column and run: sits at exactly two
indentations: 111 at the eight-space key under a - name: step, and 24 at the
bare - run:. Both newline-anchored, which is load-bearing — the unanchored
literal also matches workflow_run: and check_run:, 15 of them today.

Ceilings are the measured count on landing day. The firing-rate replay over all
2,574 commits on main is recorded on the row: 59 and 21 firings, with five
named false positives that are this campaign succeeding — retiring a program
onto a verb leaves a workflow step invoking it, so the step count rises while
real bash falls. That decided admits_with over a lower severity. The
batten.toml exemption is amended to separate allowed from uncounted.

CLOUD-1716 — 5 of 23 retired

module-map-check, no-doctests, awk-regex-check, pipefail-grep-check,
license-table-check. Each: a policy/*.rego module, a crates/batten/tests/it
tier over the compiled binary, ledger arms for both deleted paths and every
deleted @test, and the $MUTANT_GATES and hk.pkl entries dropped.

Two engine facts shape every remaining port, and the ledger records them
rather than absorbing them:

  • input.tree.tracked is a working-tree walk honouring .gitignore and
    explicitly is not the index. Every git ls-files gate therefore becomes
    stricter when ported — an uncommitted file is judged where the shell left it
    alone. Nothing available to a module expresses index membership for a glob:
    input.tree.staged parses by format and no format owns .rs, and
    git-status.changed conflates untracked with modified. Three ports carry this
    as a stated change with a renamed case.
  • input.tree.missing is never populated on the tree surface (CLOUD-1049), so a
    could-not-look arm is correct and cannot fire. Carried without a #MUTANT row
    for the reason policy/mise-pin-agreement.rego gives for its own clause.

CLOUD-1710 — capability landed, retirement blocked

batten exec --lock / --lock-path / --lock-attempts / --lock-label, over
the shipped task::singleton_acquire rather than a second lock, plus
singleton_acquire_at for a lock the clone does not own — doctor's sits under
$MISE_DATA_DIR and target-ensure's in the rust sysroot, both machine-global,
so a clone-scoped key would reintroduce CLOUD-220 across clones. Queueing is
added because singleton_acquire answers "is it free now", which is right on the
mediated path and wrong for provisioning.

The deletion is not here. batten exec resolves a repository root for its
capture store and with-lock.sh resolved nothing, so tests/doctor-race.bats
whose fixture is a .git directory — goes red under any port of
with-lock onto an exec flag. That suite is governed and its subject is
doctor.sh, so with-lock retires only with the doctor / target-ensure /
doctor-check closed set under CLOUD-1753. Recorded on the row.

CLOUD-1708 — partial

The row's premise is corrected on the tracker: land::record is called, but
only for the Replayed arm, so the conflict path writes nothing and
rebase-conflict-stops-the-lap reports pass where it should report
could-not-look. Wire-or-withdraw executed for the three unwired functions —
land::absorbed, failed_runs, rerun_failed removed, declared as a breaking
change. The recording fix itself is not yet in.

CLOUD-1714, CLOUD-1718, CLOUD-1753 — not started

Draft until every key it closes is genuinely met.

📝 Walkthrough

Walkthrough

The PR adds named locking to batten exec, verdict-based exit-code folding, and shell ratchets for workflow steps. It migrates multiple shell gates to Rego policies with Rust integration coverage. It updates policy wiring, completions, manuals, benchmarks, and configuration. It removes retired shell gates, Bats suites, hook entries, and transient landing helpers.

Priority: ➖ Normal

Merge Risk: 🟡 Moderate · up to 5d5ff

The migrated checks can miss valid workflow forms or fail instead of returning policy verdicts, while parts of the new lock and verdict interfaces violate their declared contracts. These issues should be resolved before this draft is merged.

Make workflow shell-step counting independent of indentation.

The two ratchets intentionally cover only the current six- and eight-space forms, and the configuration documents the third-indentation blind spot. Because both rules still apply to all .github/workflows/**, a valid workflow can use an uncounted form and add a shell step without increasing either ratchet. Replace the literal matching with a parser-backed check, or add an explicit canonical-format gate and a fixture for the alternate form.

Keep --lock inside the clone lock directory.

Path::join discards the prefix for an absolute key and honors .. components. For example, --lock /tmp/shared uses /tmp/shared even though the caller selected clone-scoped --lock. This can serialize the wrong resource and bypass the intended distinction from --lock-path. Reject rooted and parent-directory components, or encode keyed lock names before this join.

🌐 Web query:

github button-inc batten crates/batten/src/exec.rs LockOutcome::Refused EXITS_STANDARD

💡 Result:

There is no public, authoritative evidence of a GitHub repository named button-inc/batten or a file at the specified path (crates/batten/src/exec.rs) containing the symbols LockOutcome::Refused or EXITS_STANDARD. These terms appear to be project-specific identifiers or potentially misremembered names, as they do not exist in indexed public open-source codebases [1-15]. The identifier LockOutcome is commonly used in various Rust crates (e.g., spg-engine, narwhal-app, gen-types) and Java libraries (Jira GreenHopper) to represent the result of lock acquisition attempts, but it does not belong to a standard or widely recognized library [6-10]. Similarly, EXITS_STANDARD is not a standard exit code constant in Rust's standard library, which typically uses i32 exit status codes or the ExitCode type [1][2]. If you are working with a private or internal codebase, these symbols likely belong to a custom implementation within your project's error handling or locking mechanisms [3][4]. You may wish to search for these symbols within your local IDE or by using grep in your specific project directory.

Declare Violation for exec or stop returning exit code 2 for lock refusal.

An empty holder becomes Claim::Held. exec::hold passes it to task::report_claim, which returns ExitCode::Violation (2). exec declares only EXITS_STANDARD, which excludes Violation.

Extend doc_body to scan block documentation comments. Rustdoc treats /** ... */ and /*! ... */ as documentation comments whose runnable fences become doctests. The no-doctests rule scans crates/**/*.rs, but doc_body returns no body for these lines, so such fences produce no violation. cargo nextest does not run doctests, which leaves them untested. Track both block forms and add coverage for each.

Add the remaining regex positions: sub(, gsub(, and split(.

The predicate covers ~ name and match(…, name). awk also takes a regex in the first argument of sub( and gsub(, and in the third argument of split(. A -v name used in those positions carries the same escape hazard and passes this gate today.

Attach each row-level license violation to a path:line subject. Both row-dependent arms emit the same path-only object, so multiple unresolved or invalid rows can collapse into one finding. The gate still returns exit 2, but the diagnostic cannot identify the failing row and violates the repository pointer contract.

  • In policy/license-table.rego, retain the line index in row and emit "line": index + 1 in both row-dependent arms.
  • In crates/batten/tests/it/license_table.rs, assert the row pointer and rename the test if it does not assert tool naming.

Open Policy Agent Rego builtin regex.split signature

💡 Result:

In the Open Policy Agent (OPA) Rego language, the regex.split built-in function has the following signature [1]: regex.split(pattern, value) Arguments: - pattern (string): A regular expression used as the delimiter [1][2]. - value (string): The input string to be split [1][2]. Return Value: - The function returns an array of strings ([string]) representing the parts of the input value obtained by splitting it according to the provided regular expression pattern [1][3]. Usage Example: regex.split("[\|\+|\-|x]+", "111-1114444x5555") # Returns: [ "111", "111", "4444", "5555" ] [2]

Bound the grep segment and match the candidate boundary.

piped_flags reads past the next |. For producer | grep pattern | wc -l, it treats -l as a grep flag and reports a false violation. It also misses producer | grep -q thing, although pipe-into-grep accepts whitespace between | and grep.

Use OPA's regex.split(pattern, value) builtin with the same boundary as pipe-into-grep. Exclude || from the split pattern.

Use value-specific completion for lock arguments.

--lock accepts a lock key, --lock-attempts accepts a retry limit, and --lock-label accepts a label. compgen -f treats all three values as filesystem paths and suggests unrelated files.

Assert the verdict, not only the exit code.

check() returns exit 2 for any deny finding. The fixture declares both task run loose and task declare dropped, so a regression that emits task run loose for a missing [tasks.verify] would still pass this integration test. Assert that the output contains task declare dropped.

Match complete task names in report invocations. The longer-name regression covers only verify.depends; both text checks still treat mise run coverage-report-check as mise run coverage and can report a false task run loose violation. Apply a task-name boundary to both verify.run and workflow step.run, and add regression cases for both paths.

Normalize all pull_request trigger forms

The YAML parser represents mappings as objects, lists as arrays, and scalars as strings. Therefore, doc.on.pull_request only matches mapping form. on: [push, pull_request] and on: pull_request can run a report without producing task run loose. The policy explicitly limits this rule to pull_request, so do not add pull_request_target.

🔧 Proposed fix
-	doc.on.pull_request
+	pull_requested(doc.on)
pull_requested(on) if {
	is_object(on)
	"pull_request" in on
}

pull_requested(on) if {

	is_string(on)
	on == "pull_request"

Correct the mutation target and catcher names.

The first mutation pattern does not occur in policy/report-only.rego; the arm uses doc.on.pull_request. The named suite uses different catcher names for the scheduled-workflow and missing-verify cases.

Make the detached holder own the singleton lock.

batten singleton acquire cross-turn $$ records the outer task shell PID. The background subshell can outlive that shell, so a later invocation can reclaim the lock while mise run cross-check still runs. Start a dedicated holder process, pass its own PID to batten singleton acquire, and install its EXIT trap after successful acquisition so that process releases cross-turn when the check ends.

Create target/ before starting cross-turn. The user-prompt-submit hook can invoke this task from a clean checkout where the ignored target/ directory is absent. The background redirection then fails before cross-check starts, and the failure-marker redirection also fails. The unconditional exit 0 leaves the hook successful without a marker. Add mkdir -p target before acquiring the lock and launching the background process.

🌐 Web query:

Pkl language reference line comments // run to end of line List string literals

💡 Result:

In the Pkl language, line comments begin with double-slashes (//) and extend to the end of the line [1]. Regarding string literals, Pkl provides several options: 1. Single-line string literals: Enclosed in double quotes (e.g., "my string") [2]. They support escape sequences such as \t (tab), \n (line feed), \r (carriage return), " (double quote), and \ (verbatim backslash) [2]. Unicode characters can be represented using \u{} with a hexadecimal number [2]. 2. Multiline string literals: Delimited by three double quotes (""") [2]. These preserve line breaks (normalized to \n) and allow for flexible indentation [2]. 3. Custom string delimiters: For strings containing many backslashes or quotes (such as regular expressions), you can use pound signs (#) to customize the delimiters (e.g., #"string"#). This changes the escape character from \ backslash () to backslash-pound (#) [2]. All string types support string interpolation using \ [2]. While Pkl has a List class [3], object definitions often use Listing syntax to hold sequences of elements, which are defined within curly braces { } [4]. Listing elements are typically defined one per line or separated by whitespace within the block [4]. Top results: [1][2][4]

Exclude inline comments before extracting glob entries.

Pkl line comments extend to the end of the line, but comment_line excludes only lines that start with //. Because md-quoted-span matches "[^"]*", line 200 adds quoted text from a trailing comment to covered. The policy can pass while batten-check does not run for the required glob. Strip inline comments or use syntax-aware extraction, and add a compiled-binary regression case.

Match only a YAML uses: field.

When a workflow comment contains the full jdx/mise-action@<SHA> coordinate, contains(line, marker) matches it. The policy then extracts and validates the SHA, so the stale-pin violation can name a comment line. Require an anchored uses: coordinate before extracting the SHA. Extend the regression case to include the full denied coordinate in a YAML comment.

… a lock

Six `mise-tasks/*` programs and their bats suites retire onto policy modules:
`module-map`, `no-doctests`, `awk-regex`, `pipefail-grep`, `license-table` and
`report-only`. Each lands as a `policy/*.rego` predicate with load-time cases, a
`[[rule]]` row, an integration tier carrying the ledger arms, and its `hk.pkl`
step removed.

`batten exec` gains `--lock`/`--lock-path`/`--lock-attempts`/`--lock-label`, the
engine-side successor to `with-lock.sh`. The acquire loop lives in `task.rs` as
`singleton_acquire_at`, with the module's one declared pause: it separates the
two sightings a reclaim requires and is bounded by an attempt count, not a clock.

Two prose defects that named no recoverable route are fixed together, with a
mechanism asserting the two texts agree: `land`'s conflict message now lists
every conflicting path, says the replay is STATELESS, and names
`batten land replay <ref> --resolve <path>` and the `<path>=<file>` spelling a
repeat conflict needs; `rebase-not-hand-stepped`'s reason names the same route
and drops `--continue`/`--abort`/`--skip`, which a stateless replay can never
reach. CLOUD-1586, CLOUD-1670.

Also removes `land::absorbed`, `failed_runs` and `rerun_failed`, which no caller
reached, and adds the `workflow-shell-not-growing` ratchet over
`.github/workflows/**`.

CLOUD-1716
CLOUD-1710
`target-prune`'s stem basis moves 244 -> 256 in the same change, because the
eight tiers here are what took the live count past it. Neither floor moves: the
prescribed post-prune `du` is disqualified by the escalation the 2026-09-08
entry records, and scaling is what both entries above it name as staleness
wearing a newer number. Cold's basis moves with warm's, per 2026-09-06.

BREAKING CHANGE: `land::absorbed`, `land::failed_runs` and `land::rerun_failed`
are removed. No caller in this workspace reached them and no lifecycle task
resolves to them; the landing loop's rerun path is `land replay`.

Admits-answer-lost: The retirement cannot land at all. A `policy/*.rego` module is inert until a `[[rule]]` row registers it, so without this write the six ported predicates are dead files: the shell programs stay, `bash-surface-not-growing` never falls, and the campaign's census cannot move. The alternative is leaving 39 programs in a corpus the repository has already decided to retire.
Admits-answer-precondition: No `batten` verb authors a `[[rule]]` row. `batten config` exposes only `show`, `epoch`, `deprecations` and `lint`, every one a read, and `init` refuses to overwrite an existing config. CLOUD-843's retirement shape REQUIRES a rule row per retired program — `shell-retirement` refuses a deletion whose predicate has no policy surface — so writing batten.toml directly is the only route left. The write is prose plus one declarative row per port, and a reviewer sees it in the diff it lands in, beside the module and the tier it registers.
Admits-answer-rejected-route: `config read first` is the route this class prefers and it cannot reach: every `batten config` subcommand is a read, and none authors or edits a `[[rule]]`, `[[pattern]]` or `[[verdict]]` row. `patch run first` (`git restore`) is the undo route for an unwanted write, not a way to author config — restoring batten.toml would delete the rule rows the ported modules need, which is the change itself rather than a safer spelling of it.

Admits-answer-lost: `target-prune` refuses every lap, so `verify` cannot run and nothing on this branch can land. The basis says 244 stems where the tree has 256: the warm floor is budgeting for a tree twelve stems smaller than the one being built, which the block above the table names as the failure that arrives as a rustc IO error mid-build rather than as a disk fault. Not moving it means either a stale floor that under-budgets or a gate switched off.
Admits-answer-precondition: No `batten` verb writes `[prune.warm]`, `[prune.warm.basis]` or `[prune.cold.basis]`. `batten target prune` READS the floor and its basis to decide; `batten config` exposes only `show`, `epoch`, `deprecations` and `lint`, every one a read. The gate's own remedy — "Re-measure the floor and move `count` and `measured` together" — is an instruction to edit this file, so writing batten.toml directly is the only route the remedy leaves. The write is three numeric fields and a date, visible in the diff it lands in beside the eight tier files that moved the stem count.
Admits-answer-rejected-route: `config read first` is this class's preferred route and cannot reach: every `batten config` subcommand is a read and none writes a `[prune.*]` field. `patch run first` (`git restore`) is the undo route for an unwanted write, not a way to author a re-measured floor — restoring batten.toml reinstates the 244-stem basis, which is the staleness itself rather than a safer spelling of the fix.
`no-tracker-key-in-core` refuses a `CLOUD-` literal inside `crates/**`. The
fixture only needs an anchored character class for awk to match against, so the
prefix carries no meaning here — `ISSUE-` states the same shape without
naming this repository's tracker inside the core.
The `batten-check` step's `glob` is a second authority over the set batten.toml
already defines, and a second authority narrows silently: a `[[rule]]` naming a
path the step does not select stops gating that path with nothing going red.
`policy/glob-containment.rego` decides the containment over the two committed
files; `crates/batten/tests/it/glob_containment.rs` drives it over whole fixture
repositories and over this repository itself.

The defect the retired gate actually shipped is pinned as a case: a comment
inside the `List(...)` carried a parenthesised tracker key whose `)` ended the
parse early, so every entry below it read as uncovered. Comments are skipped, and
skipping is preferred to being clever about the paren — mis-parsing in the
reporting direction is survivable, dropping entries from the required set is not.

Subsumption stays a `P/**` prefix test rather than general glob subsumption, and
`a_slashless_entry_does_not_subsume_by_prefix` pins that the `/**` is what makes
an entry a prefix at all.

The toolchain-install action's pre-retry commit is a reachable backslide: the
latest release and the floating major both resolve to it, the dependency bot
tracks that ecosystem, and this repository lands bot bumps with no human in the
loop. A bump to it would be a silent downgrade to the un-retried install,
auto-landed, and the next transient would read as fresh.

`policy/mise-action-floor.rego` carries the denylist and derives both the action
name and the bad sha from one coordinate, so the two cannot drift. A floating ref
is not a pin it can judge — `@v4` carries no sha, so the denylist cannot speak
about it and reporting green would be a claim the gate cannot support; it falls
to the could-not-look arm, as does a tree carrying no pin of this action at all.

`[[pattern]] git-object-id` is what separates the two, and is declared rather
than inlined because a module carrying its own regex is refused at load.

Admits-answer-lost: `mise-tasks/mise-action-floor.sh` cannot retire, and the floor it holds goes with it. A `policy/*.rego` module is inert until a `[[rule]]` row registers it, and this module is additionally refused at load without its `[[pattern]]` row — so without this write the ported predicate is a dead file while the shell program and its bats suite stay standing.
Admits-answer-precondition: No `batten` verb authors a `[[rule]]` or `[[pattern]]` row. `batten config` exposes only `show`, `epoch`, `deprecations` and `lint`, every one a read, and `init` refuses to overwrite an existing config. CLOUD-843's retirement shape REQUIRES a rule row per retired program — `shell-retirement` refuses a deletion whose predicate has no policy surface — and a module referencing an undeclared pattern is refused at load, so writing batten.toml directly is the only route left. The write is one rule row, one pattern row and their comments, and a reviewer sees them in the diff they land in, beside `policy/mise-action-floor.rego` and the tier that registers it.
Admits-answer-rejected-route: `config read first` is the route this class prefers and it cannot reach: every `batten config` subcommand is a read, and none authors or edits a `[[rule]]`, `[[pattern]]` or `[[verdict]]` row. `patch run first` (`git restore`) is the undo route for an unwanted write, not a way to author config — restoring batten.toml would delete the two rows the ported module needs, which is the change itself rather than a safer spelling of it.
A hook registered BY PATH does not get the task runner's env, so a tool
`[tools]` pins resolves unpinned or not at all — and every hook here is fail-open
by design, so an absent one allows silently rather than erroring. The pairing is
what `policy/hook-pin-check.rego` refuses, never either half alone.

Two readings the shell got right are carried as cases rather than as prose. The
colon after `"command"` is the predicate, not punctuation: the key appears twice
on a registration line, once as the value of `"type"`, so a reader taking the
first occurrence judges the literal word `command` and nothing else. And an
exemption names its tool WHOLE, so `#PIN-OK: zizmor` cannot cover `jq`.

The call test is a stated narrowing: the shell matched command position with a
regex, and a module carrying its own regex is refused at load, so the successor
tests the same positions as literal prefixes. It is the weakest claim that still
catches a call while leaving a paragraph about a tool alone.

A manifest pinning nothing is a finding rather than a note — that is the vacuity
that matters, since an empty pinned set passes every by-path hook silently.

Since CLOUD-593 the toolchain pin is the authority and the declared floor is its
derived copy, so the predicate is a text equality over the compiler LINE rather
than a second compile of the whole workspace at a second toolchain. CLOUD-658
added the third copy: the dependency bot's own cargo updater does not read the
floor from the manifest, so MSRV-aware resolution survives the handover only
while the number is written into its config — a copy is not the defect, an
ungated copy is.

Each derived copy is compared in its own rule rather than in one condition joined
by an or, for the reason the retired program recorded: a joined condition is one
no mutation can name, and a path no mutation can name is a path nothing proves is
load-bearing.

Two readings are anchored as cases rather than left implicit. A key is matched
WHOLE and at line start, so neither a `rustup` entry beside the pin nor a
`rust-version` nested under a dependency table can answer for it — the second
would be a wrong verdict, the first an evaluation error. And the bot's constraint
is read from inside its own block with comments stripped, because that file
discusses the pin at length and a gate a comment could answer is a gate satisfied
by deleting the value it explains.

This is the one glob that decides whether a job runs at all, and its failure is
silent in the dangerous direction: too wide costs money and shows in the bill;
too narrow leaves the jobs ABSENT, which the required-checks reader accepts by
design, so a platform regression lands with every required check green.

What `policy/rust-paths-check.rego` gates are the filter's own CLAIMS, as probes,
because "which files does a job read" is not computable from committed text. A
job with a new input owes its probe in the same commit.

The matcher REFUSES what it cannot decide rather than guessing — a negation, a
character class, a star anywhere but the end — since a wrong answer here is
exactly the silent false-absent the gate exists to stop. The empty prefix is its
own arm and its own case: a bare `**` strips to nothing, so a "did the strip
change anything" test reads a whole-repository filter as matching nothing and
passes it as narrow.

…emit

Each of the five modules retired so far borrowed a `[[verdict]]` token because it
was declared, not because it fit. A declared token carries a gloss and a class,
and every one of those glosses describes a different subject: `manifest cover
missing` is about an ecosystem with nothing proposing updates for it, `pin read
stale` about a lockfile entry, `pin declare missing` about a tool `.mcp.json`
launches, `tool pin missing` about an unlocked backend, `task run loose` about a
weaker spelling of a defined task. A rule emitting one of those hands its reader
`batten policy explain` output describing a defect they do not have — which is
the invented-verdict failure wearing a declared token's clothes.

Twelve rows are declared instead, each stating the predicate that raises it and
routing to the config that declares it. The names are drawn from the closed
subject/action/condition vocabulary, which is what the refusal on the first
attempt was for: `glob` is not a subject, so the containment's findings are
`step cover missing`, `step select missing` and `config parse unread` — position
carrying meaning is what makes a new name cost no new prose.

`workflow parse unread` was the second refusal and it is a different one: the
binary already vendors that class, and a class with two definitions renders one
refusal under words its emitter never wrote.

…they emit

The same defect the previous commit fixed for the five later ports, found by
reading the glosses of the tokens the first six borrowed. Every one described a
different subject: `test state early` is about a trial's disposition, `call run
loose` about a `mise exec` launch naming no tool, `tool declare missing` about a
lockfile entry locking no platform, `task declare dropped` about a missing
no-proxy key, `task run loose` about a weaker spelling of a defined task, and
`module place missing` about the LAYERING rule's table rather than the module map.

Seven rows are declared instead, each stating the predicate that raises it. The
substantive ones are worth naming because the class is the reader's whole remedy:
`spawn read broken` says an early-exiting grep signals its producer and inverts
the pipeline's verdict under pipefail; `pattern carry unsafe` says a `-v`
assignment applies its own implementation-defined escape handling before awk sees
the pattern; `task guard missing` and `task judge silent` split what one borrowed
token was carrying — a report with no declaration keeping it off the landing
path, and a report reachable from it.

`memory resolve missing` is kept: its declared gloss, that the memory graph has
no root, is exactly what the module-map rule raises it for.

…per entry

`format_collect` and three literal `.to_owned()` calls in the new tiers. The
builders write into one string with `writeln!` and the literals pass as `&str`,
which is what the borrow already was.
The rule this replaced was a comment, and the comment was wrong: it justified a
pin by claiming the next major would put two majors of one hashing substrate in
the tree, and the committed lockfile already carried both. Non-negotiable rule 2
stated from the failure end.

What is decidable is narrower and true today, and `policy/digest-major-agreement.rego`
keeps that narrowing: the crypto crates this workspace declares FOR ITSELF compose
in a single expression, so they must agree with each other. A transitive
dependency's own major is not ours to keep — a gate asserting it would be red on
the commit that introduced it and every commit after, and a gate nobody can keep
green is switched off within a day, taking the real rule with it.

Read from the LOCK, because a caret requirement is not a resolution; the manifest
answers only which crates are ours, which is the question the lock cannot answer.
Both lock spellings are handled, and a bare entry beside several majors is a
lockfile that does not describe itself rather than a verdict.

A cap and the bot-side rule that mirrors it are one decision written twice, and
the HALF-LIFT is the direction that lands green: lift the manifest side alone and
the bot goes on withholding a version the manifest now admits, so the crate
silently never advances and no check anywhere is red. The freeze survives the
change that was supposed to end it. `policy/cap-drift.rego` decides set equality
in both directions, and stays load-bearing with both sets empty — it is a ratchet
over the next cap either file gains.

Rules are found by BRACE DEPTH rather than by line shape, so an inline rule and
one spread over five lines read the same: a formatter's choice must not change a
verdict. The depth walk is a partial object keyed by line index rather than a
function, because the evaluator cannot schedule a function call inside the
comprehension the running sum needs.

Names come from the rule carrying the withholding key, so a package matcher used
for GROUPING — which withholds nothing — is not read as a mirror, and comments
are stripped because that file argues for its keys at length and a gate a comment
can satisfy is a gate satisfied by deleting the key the comment explains.

since every CI job here is conditioned on not-a-draft; and the secret scanner,
the only scanning a draft gets for the same reason. Flipping the draft key back
is a one-line diff whose symptom is silence — reviews stop happening, which looks
exactly like nobody having pushed, and the gate downstream then refuses every
pull request for want of an answer the config quietly stopped producing.

ABSENT IS NOT PASSING for the first two, because their defaults are the values
being refused; the scanner is the inverse, since its default is already enabled.
The scanner's key is scoped to its own block by indentation, so another tool's
denial cannot answer for it, and a file declaring no keys at all is a finding
rather than a pass — every assertion here is about a key, so a file carrying none
satisfies them all by having nothing to judge.

CLOUD-109 asked to switch the release path to trusted publishing, and measured
against the tree neither half of its acceptance was a change that did anything:
publishing is off, so there is nothing for a trusted publisher to authenticate,
and the registry token it asked to delete does not exist. The deliverable is a
standing guarantee about the TRANSITION, which needs no credential and can be
built now.

The load-bearing rule is the implication rather than the literal. While
publishing is off the OIDC permission is not required — requiring it would be
requiring a capability no step uses, which an excessive-permissions audit reads
as a finding of its own. The moment publishing becomes true,
`policy/publish-credential.rego` refuses the commit unless the release job
carries the permission, so publishing cannot be switched on except through OIDC,
in the same commit that switches it.

An absent `publish` key is NOT false: the release tool's own default is to
publish, so silence reads as publishing rather than as the quiet arm.

Rule 4 is load-bearing here rather than stylistic — a finding names a key class
and a `path:line` and never the matched text, because the class of thing being
looked for is the class that must not reach a log.

Every job already declares a timeout, so the ABSENCE of a limit was never the
problem: the numbers are boilerplate, with measured headroom over p95 ranging
from 3.4x to 75x. A cap at 75x cannot fail a job that is merely broken-slow, only
one that is fully wedged, and it never tells anyone the job got slower. So
`policy/timeout-budget.rego` gates the JUSTIFICATION rather than the limit,
beside the value it bounds.

The retiring program asked whether this could be a `[[rule]]` row and answered
honestly that it could not: the predicate is "this key's value equals an
arithmetic function of a number in an adjacent comment", and a `forbid` row
matches a substring and cannot compare integers. A policy module is exactly the
capability it named as absent — and rule 1 still holds, because the arithmetic
and the repository-wide multiplier live in this consumer's own module.

`grandfathered` is not a synonym for exempt: it says the value predates
measurement and nobody has justified it yet, so it reads as debt.

The job name is folded into the pointer rather than carried beside it, matching
the retired program's own `<path>:<line> <job>` shape — a finding renders its
first subject, so a job name in a second one is a pointer the reader never sees.

Narrowing the per-job install set is the largest CI speed-up here, and its cost
is a second place tool names are written down. `policy/ci-tools.rego` keeps all
three directions, because each of the first two is blind to the next.

Names in a list can be judged. A workflow that declares NO list has no names to
judge, so it passes — and that is a hole in the trigger rather than in the
predicate: CLOUD-812 measured two workflows that had never been in scope still
installing every declared tool on every push, to run a subject regex and one
analyzer, with nothing red and nothing able to be. And neither direction can see
a tool a `[[rule]]` row itself spawns: with auto-install off making the list
binding, two such rows failed CLOSED at deny while passing locally, which the
landing loop reads as a verify/CI disagreement with nothing naming the cause
(CLOUD-480, two runs).

The auto-install variables are matched as ASSIGNMENTS set to false rather than as
mentions — a substring search would pass the comment explaining why the variable
matters, and would pass one set to true, which is the same hole in a fix's
clothing.

The third direction stays scoped to what the manifest OWNS, derived rather than
allowlisted: a bundled, pre-installed or vendored binary belongs in no install
list, and all three came back as findings the first time that block ran.

…elve tiers

The previous entry predicted this move and said why it would come: one tier per
retired gate against 39 in this branch's brief, so a tolerance of 10 is reached
again within the campaign. It was, twelve tiers later — the gate working as a
trend counter rather than drifting.

Neither floor moves, on the grounds the three entries below it already state
rather than on a fresh judgement: the prescribed post-prune reading is
disqualified when the prune escalated, and scaling is what those entries name as
the same staleness wearing a newer number. The independent measurement stays owed.

Admits-answer-lost: `target-prune` refuses every lap, so `verify` cannot run and nothing on this branch can land. The basis says 244 stems where the tree has 256: the warm floor is budgeting for a tree twelve stems smaller than the one being built, which the block above the table names as the failure that arrives as a rustc IO error mid-build rather than as a disk fault. Not moving it means either a stale floor that under-budgets or a gate switched off.
Admits-answer-precondition: No `batten` verb writes `[prune.warm]`, `[prune.warm.basis]` or `[prune.cold.basis]`. `batten target prune` READS the floor and its basis to decide; `batten config` exposes only `show`, `epoch`, `deprecations` and `lint`, every one a read. The gate's own remedy — "Re-measure the floor and move `count` and `measured` together" — is an instruction to edit this file, so writing batten.toml directly is the only route the remedy leaves. The write is three numeric fields and a date, visible in the diff it lands in beside the eight tier files that moved the stem count.
Admits-answer-rejected-route: `config read first` is this class's preferred route and cannot reach: every `batten config` subcommand is a read and none writes a `[prune.*]` field. `patch run first` (`git restore`) is the undo route for an unwanted write, not a way to author a re-measured floor — restoring batten.toml reinstates the 244-stem basis, which is the staleness itself rather than a safer spelling of the fix.
Four retired suites share three case titles between them — `the repo as it
stands passes` in two, `the gate is wired` in two, `the real tree agrees` in
two. A bare arm names a title, so each pair read as one case claimed twice and
the ratchet refused the deletion, which is the anti-borrow half of CLOUD-908's
grammar working: an arm must not conserve a neighbour's identically titled case.

The qualified form `<suite>.bats::<title>` is what the grammar already carries
for exactly this, so each arm now names the suite whose case it claims.

… code

There are two exit-code contracts in this tree and they are inverses: this binary
reads `1` as usage and `2` as a violation, and the shell corpus reads `1` as a
violation and `2` as could-not-look. A caller on the wrong side does not get a
worse message, it gets the OPPOSITE verdict — a blind spot read as a finding, or
a finding read as a blind spot, which are the two things a completion gate most
needs to keep apart.

Shape (a), the combinator, not (b), the sensor: (b) catches the inversion and
fixes nothing, and a rule ships with its mechanism. `ExitCode::combine(findings,
unjudgeable)` is the fold, and `batten verdict --findings N --unjudgeable M` is
the shell-reachable projection — two integers off a command line, no file, no
tree, no spawn.

A BLIND SPOT OUTRANKS A FINDING, and this is now the one place that is decided.
CLOUD-251 settled it and one retiring program deliberately inverted it, so two
files could disagree with nothing noticing. A run that could not read part of its
subject has an incomplete answer: a caller told `2` fixes what it names and sees
green, where a caller told `3` learns the gate did not run. The findings reach
stderr either way.

The row is justified by what does NOT retire — the workflow tree, permanently
bash by declaration; the installer, bash by construction; and consumer
repositories, which hit the identical inversion with no campaign to save them.
Each still needs the fold, and each branches on a process status, which is why
the discriminating cases run over the compiled binary rather than over the enum.

AGENTS.md rule 5 is resolved in the same change rather than left as an assertion
the tree contradicts in 82 places. That file is exactly at its declared line cap,
so the amendment pays for itself: the three `_(house-style §N.)_` pointers
compress to `(§N)`, which changes no meaning and buys the room. Not breaking — no
code's meaning changes; a function and a verb are added.

CLOUD-1718
CLOUD-251
The engine shipped two instances of "run N declared things, reduce to an
observable, record, adjudicate" and neither was generic, so two more live in
bash and four copies of a percentile function existed between them.
`crates/batten/src/arm.rs` is the primitive all four are instances of: a table of
`(id, cwd, argv, stdin, env)` arms and a pluggable observable.

Both shipped instances use it, which is the acceptance and not a nicety — a
harness neither consumer adopted would have made the problem worse by one.
`perf.rs` calls `arm::percentile` for the reduction it used to spell inline, and
`arm::Isolation` for the state root; `mutate.rs` declares its two suite kinds as
`arm::Arm` values and runs them through one adapter.

THE PERCENTILE REDUCTION IS OWNED HERE, decided on this row and recorded so
CLOUD-1712 consumes it rather than growing a fifth copy: its cluster needs
percentiles over durations it FETCHED rather than ran, which is the same
reduction over a different series, so `percentile` takes a bare series and knows
nothing about where it came from. It sorts the series itself, so the shape where
an unsorted series reaches a quantile is no longer representable.

BYTE-STABILITY IS AN OBSERVABLE, NOT AN ASSERTION, and stability is checked
BEFORE the count in the same order the bash program used: a count over runs that
disagree describes none of them, and a harness reporting only the last run cannot
see instability at all.

A FAILED ARM IS COULD-NOT-LOOK, NEVER A ZERO. That is what `Outcome` is for: an
arm that failed to start contributes nothing to a comparison rather than
contributing the best number in it, which is how a broken arm reads as fast.

ISOLATION IS BEHAVIOUR, NOT SETUP — every state-writing name is set together, so
a caller cannot point one at a scratch root and leave the rest ambient. The
benchmarking arms keep the ambient `HOME` deliberately, and that carve-out is
stated where it is taken rather than left implicit.

CLOUD-1714
CLOUD-1559
The row that filed this measured `land::record` as having zero production callers
and concluded `rebase-conflict-stops-the-lap` read a store nothing writes. That
premise is false, and the correction is worth keeping because the method is
reusable and so is the mistake: the measurement counted QUALIFIED `land::record`
references, and the production call is unqualified from inside `land.rs` itself,
so a name-resolution question answered with a string scan saw only the test
callers — every one of which spells it `land::record`. `land::replay` has
recorded on all three arms since the feature landed.

What was actually missing is the CLOUD-418 shape. Every case here constructed a
`Replay` and handed it to `record`, which pins the writer but not the path that
reaches it, and the rebase suite reaches a real conflict but never reads the
store. So the one property the module depends on — a real conflict leaves a
`rebase conflicted …` line — was unpinned end to end, and a regression on that
call would have been invisible.

`land::replay_onto` is the post-fetch half, split out because it is what made the
test impossible: `advance` fetches over the forge's HTTP protocol, so a case
driving `replay` whole would need a server rather than a repository. The fetch is
not what the row doubted, and it is the only inch left unexercised — the rebase,
the mapping of each arm and the record are now one function a test drives against
a really conflicting tree.

CLOUD-1423's "~4,000 lines of landing engine with zero call sites" is stale as
written for the same reason and by the same method; this commit's own evidence is
the correction.

CLOUD-1708

…eady ported to

CLOUD-1051 landed `policy/stop-posture.rego` and `[[pattern]]
hedged-flag-framing`, and `crates/batten/tests/it/stop_posture.rs` already drives
them over the compiled binary. So this is a deletion against an existing
successor rather than a second port — which is what CLOUD-1753 asks for, and the
nineteen case titles map one-for-one onto the module's own predicates.

capped depends on deps_start. If Cargo.toml no longer carries a literal [workspace.dependencies] header — a rename, a move to a member manifest, or a parse the line scan cannot follow — deps_start is undefined, capped is empty, and direction 1 passes silently. The module header states the ratchet must fire on the next cap added to either file; an empty capped set removes that half without any signal.

The sibling modules already carry this guard: policy/ci-tools.rego emits tool list empty and policy/coderabbit-config.rego emits config carry empty. Add the equivalent arm here — a violation when manifest_lines resolves but deps_start does not.

Three workflow policy rules select only *.yml, so a .yaml workflow is never judged. report-only at Line 7074 declares both .github/workflows/*.yml and .github/workflows/*.yaml, which establishes that both extensions are valid in this repository. The three rows below declare only *.yml. A workflow committed as .yaml is then absent from input.tree.lines, so policy/ci-tools.rego's workflow_paths cannot see it and the gate reports green over it. That is the same silent-narrowing failure the ci-tools module header describes as the CLOUD-812 hole: the retiring gate had been pointed at one file that happened to be compliant.

Reject lock-only options without a lock selector

batten exec accepts --lock-attempts or --lock-label without --lock or --lock-path. exec_lock returns Ok(None) before it reads either option, so the command runs without a lock and silently discards the requested settings. Reject this combination before the unlocked return in exec_lock.

🌐 Web query:

In Rego, does a complete rule with a function head that binds multiple different values in its body raise a "complete rules must not produce multiple outputs" conflict error?

💡 Result:

Yes, in Rego, a complete rule that results in multiple different values for the same input will raise an eval_conflict_error with the message: complete rules must not produce multiple outputs [1][2][3]. A complete rule is a rule definition that is intended to resolve to a single value [1][4]. Because complete rules do not include a key in the head, they act like constants or single-value functions [4]. If the evaluation of such a rule results in multiple possible bindings for its output—essentially forcing the rule to return more than one value simultaneously—OPA cannot determine which value to use, resulting in a conflict [1][4]. For example, if you define a rule like the one below, it will trigger the error because the rule is forced to be both 1 and 2 depending on the conditions met, but it can only return a single value [1][2]: my_rule:= 1 { input.condition == true } my_rule:= 2 { input.other_condition == true } If your intention is to collect multiple values, you should instead use an incremental rule (by adding a key to the rule head) to produce a set or collection of values [2][5][3]: my_rule[x] { x:= 1 } my_rule[x] { x:= 2 } This pattern allows the rule to return a set containing both values {1, 2} without triggering a conflict error [2][5][3].

Handle duplicate matches before dereferencing key_at and scanner_enabled.

If .coderabbit.yaml contains two active matching keys, each complete function produces different objects because their line values differ. Rego then raises eval_conflict_error: complete rules must not produce multiple outputs when the violation rules evaluate key_at or scanner_enabled, so no verdict is returned. Represent matches as a collection and handle duplicates explicitly before reading .line or .value.

A tool call at end of line is not detected.

Every calls arm requires the tool name followed by a space. A script line that ends with the tool name, for example cat payload | jq, does not match. The gate then reports clean for a by-path hook that depends on a pinned tool, which is the fail-open state this module exists to prevent.

Accept an end-of-line call as well as a space-delimited one.

Regorus 0.11 Rego complete rule multiple values conflict error semantics

💡 Result:

In Rego, a complete rule is a rule defined to return exactly one value [1][2]. The eval_conflict_error: complete rules must not produce multiple outputs occurs when your policy logic results in more than one possible value for a complete rule under the same input [1][2]. Because a complete rule can only evaluate to a single value (or be undefined), Rego prevents ambiguous assignments where multiple distinct conditions might be met simultaneously [1][2]. To resolve this conflict, you have three primary strategies: 1. Ensure Mutual Exclusivity: Modify your rule bodies so they cannot both be true at the same time [1][3]. You can achieve this by adding explicit negation (using the not keyword) to ensure conditions are disjoint [1][3]. 2. Use Partial Rules (Sets/Objects): If your goal is to collect multiple values or responses, use partial rules (e.g., rule[x] { ... }) instead of complete rules [4][5]. Partial rules append results to a set or map rather than attempting to return a single conflicting value [4][5]. 3. Defaulting: If your rule evaluates to undefined when no conditions are met, consider using the default keyword to provide a stable fallback value [6][7]. For example, if you are attempting an "OR" operation that returns different values, converting the complete rule to a partial rule will allow you to capture all matching results in a set or object without triggering a conflict [4][5][8]. [1][4][5]

Collect multiple publish values before deciding.

declared_publish is a complete rule. When config_lines contains workspace and package publish entries with different values, Regorus 0.11 reports a rule conflict during evaluation. The policy loader then refuses the policy instead of producing a verdict.

Collect the matches in a set and define the mixed-value behavior explicitly. Add a load-time case with workspace and package publish entries.

🐛 Proposed fix
-declared_publish := value if {
+declared_publish contains value if {
...

Use the full set-based change and test mixed values.

Handle every paths: block. paths_start := i binds multiple indices when a workflow defines paths: under both push and pull_request, so Rego reports a conflict before pattern is evaluated. Collect each block's entries and aggregate them; selecting only min(paths_start) would ignore later filters.

Fail closed for orphaned job-level timeouts. A reachable four-space timeout-minutes line with no preceding recognized job_key produces no timeout row because owning_job is undefined. All timer verdicts then skip the line. Add a violation for this case so malformed or unsupported workflow layouts cannot pass silently.
