`runExecutionLoop` took `prompted: boolean` as its fifth argument, and every one of its six call sites passed the run's own persisted flag. Four spelled it `!!state.prompted` or the equivalent; the other two passed a value core had already derived from `Boolean(state.prompted)` or written to the row with `manager.create`. The loop loads that same state on its first line. So the parameter never configured anything. It was a way for a caller to disagree with state about a fact state owns, and nothing used it that way. The loop now derives `prompted` once above the `while`, because the flag is fixed at run creation and cannot vary across iterations. `LifecycleLoopDirective.prompted` goes with it: it existed only to feed that argument from `runSeamTransition`, and with the argument gone it is a second copy of a persisted flag. The directive now says only whether to run the loop. `launchInlineChildFromIntent` keeps its own `prompted` parameter, which is a different fact — the value a composing parent inherits DOWN into a child run that does not exist yet and so has no persisted flag to read. The resumed-child branch beside it already read `!!existingChild.prompted` rather than the parameter. Behaviour-neutral prefactor for #799: the entry seam that follows derives `prompted` from state, so removing the parameter first keeps that change to one concern.
The CLI execution loop rendered the unit it was about to enter — merged
effective variables, built the step frame, chose which expander applied to
which field, assembled a `StepEntryMetadata` — and then read its own rendered
command back out to decide what to do next. `expandedCommandCode === undefined`
was its control-flow signal for "nothing to run".
`RunbookActorService.enterExecutionUnit({ state, steps })` now renders,
observes and classifies, returning a three-arm union: `awaiting` (one arm for
prompted mode, a prompted-FOR step, and a unit with no command), `runnable`
(carrying the expanded command, its display projection and the `RD_*`
environment), and `inline-launch` (carrying the prepared intent). The loop
sends state and steps and reads back a classified entry. It renders nothing,
and derives exactly one fact for itself — whether the cursor is on a substep —
because the missing-deriver authority precondition must answer that before any
entry exists.
The command is ONE value, which is the property that matters: the string
announced in `STEP_ENTERED.commandCode` and the string handed to
`EXECUTE_COMMAND` come from one expansion, so a non-deterministic `--helpers`
helper cannot make a runbook run something other than what it announced. That
was held by statement ordering; it is now held by construction. The comment
that ordering carried was wrong — the sync expander reduces to `substituteText`
and touches no manifest — and is replaced rather than moved.
`RenderedUnitCommand` carries a tier-1 phantom brand minted only inside
`deriveExecutionUnitEntry`. Two ESLint rules make it load-bearing: the `as`
cast is banned outside the producer, and front-end `src/**` may no longer
import `buildStepVariables`, `expandLoopVariables`,
`expandLoopVariablesForCommand`, or `deriveExecutionUnitEntry`.
`hasCommand` becomes a field on the entry, derived from the parsed unit rather
than from `commandCode !== undefined`, so it stops being an accident of which
builder ran.
The unfenced frontier seam sheds its `entry` parameter: it read only
`isSubstep`, and now derives that from the state it holds. It enters through the
same seam with the verified bearers attached and returns the classified entry.
Consume-before-disclosure is unchanged.
Two behaviour notes: helper containment resolves against `manager.cwd` (the
canonicalised directory the service already used for artifact projection), and
a run with no `ContextId`/`WorkPath` is refused `InvalidRunbookStateError`
rather than a bare `Error`.
The #816 characterisation stays green — collect still builds its own partial
entry. The two loop-half assertions moved from the mocked loop onto the real
derivation in core, unchanged in what they assert.
Entering substep 1.1 via `rundown run` produced a `STEP_ENTERED` carrying its description and prompt. Entering the same substep of the same runbook via the RETRY re-entry `rundown collect` drives produced one carrying neither. Two functions built the payload's `StepEntryMetadata` and they disagreed; all four rendered fields are optional on the type, which is what let that compile. The collect path now enters through the same core seam the loop does. The hand-built entry is gone, with the Stryker equivalence annotations that existed only because half its fields were never observed. Three #816 assertions flip: - `description` / `prompt` are present on the collect payload, end to end, and equal to the run payload's for the same unit. - `prompted` composes the persisted flag with the step kind, so a prompted-FOR step reports `true` on both paths rather than `false` on one. - `substepId` comes off the resolved unit rather than the raw cursor, so a cursor naming no live substep no longer yields a populated `substepId` beside `isSubstep: false`. That matters beyond tidiness: the frontier seams gate credential disclosure on `isSubstep`. The FENCED frontier seam sheds its `entry` parameter, as its unfenced twin already had: it derives the substep question from the state it holds and returns the projected bearers. No caller can hand either seam an entry that disagrees with the run. Two guards are deleted rather than left unreachable. `deriveStepEnteredEffect` refused an entry whose cursor disagreed with the snapshot; with one producer reading both off the same `RunbookState`, that mismatch is unrepresentable. `observeExecutionUnitEntry` goes with them — the collect path was its last caller — and `StepEntryMetadata` becomes a local between two core functions. A new failure surface, named: a committed collect can now fail to RENDER the entry its bearers ride on, where before it emitted a thinner event needing no rendering. Nothing recovers the bearers, so it still rejects rather than reporting a phantom success — now as RD-833 (`DELEGATION_FRONTIER_DISCLOSURE_FAILED`) rather than bare RD-999 "Unknown error", whose envelope cannot carry this recovery. An `InvalidRunbookStateError` render refusal keeps its class so RD-309 still prints finish/stop/prune. Disclosure ordering is unchanged and still asserted: the commit lands before the entry is derived, so a refused transaction consumes nothing and discloses nothing. One narrowing: the artifact-path projection used to fall back to `WORK_DIR` for a run with no `WorkPath` while the render context refused it outright, so the fallback could only produce an entry whose artifact and helper paths named different roots. One read now, and such a run is refused on both paths.
…y seam Two gates ran over the three preceding commits: `/code-review high`, and `test:mutate:changed` over every changed range. This is what they found. REVIEW. - RD-833 was swallowing corrupt-snapshot failures. `enterExecutionUnit` runs `assertFreshSnapshotValue` and `compileMachineFromState` BEFORE it renders anything, and both threw a bare `Error` — so a collect whose committed target carried an unparseable `stateValue` reported "fix the helper and re-delegate" when the real recovery is prune/restart. Both guard families now raise `InvalidRunbookStateError` with typed reasons, which routes them to RD-309. Every other caller gains the same envelope; pinned end to end through the unmocked seam. - Consolidating `buildRunnableRenderContext` into core was mine and out of scope, and it reclassified `getRunbookFromState`'s failure — which `terminal-command.ts` treats as "this run is unusable", so `rundown stop --claim-id` would have exited 0 on a run missing `WorkPath`. Reverted. Both copies now say why they are two and what deciding it requires. - The ESLint override for the brand producer dropped the parser dynamic-import selectors, making that file the only source file where they did not apply. - Checked and NOT reachable: the raw-vs-canonical `cwd` split. The CLI always passes `process.cwd()`, which Node returns already resolved. MUTATION. `execution-unit-entry.ts` scored 59.2%, and reading its survivors was worth more than the score. Five branches were provably dead, each a second spelling of a fact the types already carried: `currentStep.kind === 'command'` and `=== 'for'` (both now structural `in` checks), two of the five inline-intent identity checks (`entry.stepId` IS `state.step`; the entry's `substepId` check subsumes the raw cursor's), and an outer `typeof state.snapshot` guard the optional chain already answered. `snapshotForEntry`'s cursor overlay went with them — it existed to satisfy guards #820 deletes, so nothing read it. The module is now 100%, 98/98, no survivors and no timeouts. Three suites were covering code they did not own: - `re-entry-frontier.test.ts` never touched the FENCED twin — the function #820 changed most — reaching it only through collect. Nine cases added. - `findStepOrThrow` was new and untested. - The typed defects added above were themselves untested: `{ runId, reason }` collapsed to `{}` unnoticed, and that payload is what `finishCollection` reads to choose between RD-309 and RD-833. Two loop survivors were real. The guard that stops an inline launch off a projected frontier had no test. And the loop's `prompted` local turned out to have exactly ONE consumer left after #819 — the value a composing parent inherits into a fresh inline child — which is now said in the code and pinned by an integration pair. Recorded rather than chased, with the evidence for each: - `goto-workflow`, `runbook-pipeline`, `transitions`, `collect` survivors sit on character-identical pre-existing expressions. Removing the argument let Biome reflow the call, pulling untouched lines into the diff-derived range. - `Errors.frontierDisclosureFailed`'s ArrowFunction mutant is a STATIC mutant jest's module registry defeats. Hand-verified: editing the source to `() => undefined` DOES fail the test. - `state.prompted ?? true` is equivalent — `RunbookStateManager.create` has one production call site and its `prompted` is a required boolean. Hand-verified, as was its `&& false` sibling, which is NOT equivalent and dies on the integration pair.

`tone_instructions` folded to 502 characters. The schema caps it at 250, so CodeRabbit rejected the file and reviewed with DEFAULT settings — silently, and for the whole config, not just that field. Every path instruction and pre-merge check in here has been inert. Rewritten to 246. The semver clause survives because CLAUDE.md forbids raising it as a finding at all; the focus list is compressed, and "flag action-type mapping violations" is dropped as a named item since it is one of the CLAUDE.md design principles the value still points at. The longer policy text lives in CLAUDE.md, which `reviews.path_instructions` already directs the reviewer to. The limit applies to the FOLDED value, not the source lines, which is what made a `>-` block hide it. A comment on the field records that, and the whole file now validates against schema.v2.json — `tone_instructions` is the only 250-cap field in it, and nothing else is close to its own limit (longest path instruction is 806 against a 20000 cap; longest custom-check name 28 against 50).

entry and that rundown collect routes through enterExecutionUnit. Remove the
outdated claim that collection builds a partial entry, while preserving the

- Around line 46-49: Expand the RenderedUnitCommand assertion rule around
renderedUnitCommandCastSelector to also reject angle-bracket assertions and
detect aliases or qualified type references using type-aware linting, while
preserving the existing provenance message and direct-cast coverage.
In `@packages/cli/__tests__/integration/inline-child-launch.test.ts`:
- Around line 433-474: Extract the duplicated parent/child fixture setup from
the composing inline-child tests into a shared writeComposingParentAndChild
helper, parameterized by the child body. Update both tests to use it with their
respective child content, preserving identical parent and child runbook
structure while keeping each test’s prompted-mode difference.
In `@packages/cli/src/services/execution.ts`:
- Around line 1172-1196: Update the prompted-state handling around the prompted

existing typed invalid-state path. Remove the false fallback and preserve the
current boolean behavior for valid persisted states.
In `@packages/core/__tests__/runbook/collection-service.test.ts`:
- Around line 2723-2754: Rename the test case around collectDelegationOutcomes
to describe its actual assertions: a cursor with no live substep remains
already_collected, does not enter an execution unit, and preserves the persisted
frontier. Remove the misleading payload-omission wording from the test title.
In `@packages/core/__tests__/runbook/execution-units.test.ts`:
- Around line 33-42: Update findStepOrThrow to raise InvalidRunbookStateError
instead of a bare Error when the requested step is missing. In
packages/core/__tests__/runbook/execution-units.test.ts lines 33-42, assert that
both refusal tests throw InvalidRunbookStateError in addition to matching the

In `@packages/core/src/events/execution-observation.ts`:
- Around line 202-217: Update the barrel exports rooted at events/index.ts and
packages/core/src/index.ts to keep StepEntryMetadata, StepEntryObservationInput,

Rendering can invoke non-idempotent --helpers JS; committing first means a failed commit no longer leaves a side effect a retry would re-run, mirroring the pattern finishCollection already used for the fenced twin. - Deduplicated findStepOrThrow: the CLI and two core modules (collection-service.ts, completion-service.ts) each carried their own copy; all three now import the canonical implementation from execution-units.ts. - deriveExecutionUnitEntry accepts an optional caller-precomputed position instead of always re-deriving one. The CLI execution loop already computes this once per iteration for its own error-reporting events and now forwards it rather than repeating the countNumberedSteps scan. - Corrected a misleading comment on runExecutionLoop's prompted fallback: RunbookState.prompted and CreateOptions.prompted are genuinely optional at the type level; the fallback is unreachable only via call-site discipline. Each fix is TDD'd with regression tests, and the behavior-bearing changes (re-entry-frontier.ts, execution-unit-entry.ts, the CLI position threading) are pinned at 100% scoped mutation coverage.
Nine CodeRabbit findings from two review passes over #817/#819/#820's execution-unit-entry seam, each verified against the code before this commit (not just the diff) via independent audits. - `RunbookState.prompted` is now required, not `boolean | undefined`. `create()` always writes it; `load()` refuses a persisted row without it (`InvalidRunbookStateError`, reason `missing_prompted`) instead of defaulting an absent flag to automatic mode. Every read site's `?? false` / `!!` fallback is gone — the type carries the guarantee. - `findStepOrThrow` takes the run id and raises `InvalidRunbookStateError` (reason `cursor_step_not_in_runbook`) instead of a bare `Error`, so a diverged cursor routes to RD-309 (prune/restart) instead of being relabelled RD-833 ("fix the helper and re-delegate") by the collect path's catch-all. - `RunbookActorService.enterExecutionUnit` is declared `async`, so the three refusals ahead of the render (`assertFreshSnapshotValue`, `compileMachineFromState`, `deriveExecutionUnitEntry`) reject the returned promise instead of throwing in the caller's own tick — a `.catch()` or `Promise.all` caller previously observed none of them. - `packages/core/src/events/index.ts` re-exports the entry-seam's observation surface by name instead of `export *`, so `StepEntryMetadata`, `StepEntryObservationInput` and `deriveStepEnteredEffect` are no longer reachable from `@rundown-org/core`'s public barrel. Pinned by a new `entry-seam-barrel` test pair (runtime + typecheck). - The `RenderedUnitCommand` provenance ban is now a type-aware ESLint rule (`eslint-rules/no-rendered-unit-command-cast.mjs`, `local/no-rendered-unit-command-cast`) rather than a `no-restricted-syntax` selector set. Selectors match identifier TEXT, which is an unbounded enumeration problem — an import rename (`RenderedUnitCommand as Local`) produces a spelling no selector anticipates, and demonstrably slipped past the prior set. The new rule resolves the asserted-to TYPE through the checker and walks its symbol, base types, and union/intersection members, so a rename, a two-hop alias, or an interface that inherits the brand all resolve to the one declared symbol and are caught the same as a direct cast. `scripts/__tests__/eslint-brand-cast-guard.test.mjs` gained a case per route. `@typescript-eslint/utils` added as an explicit devDependency per this repo's strict-pnpm-layout convention. - Test-hygiene and doc-accuracy findings: a misleading test title in collection-service.test.ts, a duplicated parent/child fixture in inline-child-launch.test.ts, and stale prose in .changeset/core-entry-seam.md and .coderabbit.yaml describing contracts the code no longer has. `pnpm run check:lint:typed` is clean repo-wide; the affected package suites pass, including 5907/5911 in core (3 pre-existing, unrelated sandbox-timeout failures in executor.test.ts).
Closes the two CI failures on PR #827. **scenarios — the brand-cast guard had never passed in CI.** It was added in f9aa93d and went red on its first run; it only ever passed on warm developer trees. `lintText(snippet, { filePath: <a real project file> })` is unsound with type-aware linting. typescript-estree's `getAstFromProgram` compares the file EXTENSION and nothing else before returning whatever `SourceFile` the watch program already holds for that path, so keeping ESLint's text and the checker's AST in step rests entirely on an invalidation path — a content hash in `parsedFilesSeenHash`, a watcher callback keyed by a path canonicalised through `ts.sys.useCaseSensitiveFileNames` — that is sensitive to platform and program state. When it does not fire you get exactly what CI showed: ESLint reporting positions against a 4-line snippet while the rules walk the 1151-line module that lives at that path. The crash node's `range: [3009, 3166]` lands precisely on `releaseRunbook(` at collection-service.ts:62, which is how the mismatch was confirmed rather than inferred. `jsdoc/check-param-names` then indexed a source line past the end of the snippet and threw on `undefined.charAt`. That is the loud half. The quiet half is the one that mattered: the program's module graph was never built against the snippet's `import ... from './execution-unit-entry.js'`, so `RenderedUnitCommand` resolved to an error type, `@typescript-eslint/no-unsafe-assignment` fired (and crashed TypeScript while formatting the type name for its message), and the rule under test had nothing to resolve and silently never fired. A test that cannot see its subject fails for a reason unrelated to the subject. Each case is now written to a real `.ts` file in `packages/core/src/runbook/` and linted with `lintFiles`, so the bytes ESLint reads and the bytes TypeScript reads are the same bytes and no invalidation is ever required — the failure mode is removed by construction rather than by timing. All fixtures are written before the first lint so every one enters the program on its initial build. The directory is load-bearing for the same three reasons the path always was: it is inside `tsconfig.eslint.json`'s include, it lands in the same flat-config block as production core source, and it makes `./execution-unit-entry.js` resolve to the REAL producer so the rule sees the actual brand declaration. Nothing the test proved is weakened. The rule is not stubbed, no case is deleted, no source text is asserted on, type-aware linting is fully active, and all ten laundering routes still resolve through the real checker against the real `RenderedUnitCommand`. The negative control is now written and linted through the identical path as the forgeries — a control linted differently from what it controls was proving nothing about it. Two new preconditions in `before` turn the old silent failure loud: every fixture must produce a lint result, and none may report a fatal message. Cleanup sweeps by PREFIX rather than by a recorded list, so it also clears residue from an earlier crashed run, and is wired to `before`, `after`, and `process.on('exit')` — the last covers a teardown that reaches no hook. `.gitignore` carries the matching pattern so a run killed mid-flight cannot dirty the tree. Note the fixtures deliberately violate a repo lint rule for the ~2s they exist; `verify` is `run-s`, so lint completes before test and cannot overlap. **quality-checks — cspell.** `materialises` and `TSES` in eslint-rules/no-rendered-unit-command-cast.mjs. The dictionary already sanctioned `materialise`/`materialised`/`materialising`, so the plural was the gap; `TSESTree` is added whole so the compound resolves before cspell splits it. Also folds in two mutation-gate test fixes that were outstanding: `state.ts`'s `missing_prompted` message is now asserted in that module's own dedicated suite (it was only covered in persisted-state-guards.test.ts, which the scoped Stryker run does not execute), and both substep arms in lifecycle-command-service assert `outcome.loop`, which was one unasserted line carrying eight survivors.

Use TypeScript for type safety; define explicit types instead of relying on inference
**/*.{ts,tsx}: Never migrate persisted runbook state between versions. Reject incompatible schema versions or structures and require explicit finish, stop, prune, or restart rather than silently adapting or hydrating legacy state.
UseisError(),isNodeError(), orgetErrorMessage()from the approved modules; never callError.isError()directly. Retaininstanceofonly for same-realm custom error classes.
All exported symbols require TSDoc: exported functions need descriptions, parameter and applicable return/throw tags; exported types need descriptions and non-obvious property comments; exported classes need class, constructor, and public-method documentation; deprecated items need migration guidance.
Prefer discriminated unions, typed guards, and narrowing so invalid states are unrepresentable; do not branch on raw action-type strings when a purpose-built type can encode the discriminant.
Actions such as STOP, COMPLETE, and BREAK must propagate unchanged; never silently map one action type to another, and do not create synthetic state identifiers such as~channel.

Learning: In the rundown codebase, when evolving persisted state schemas in the core package, do not perform automatic migrations. Instead, implement a roll-forward approach: detect stale or incompatible state and prompt the user to take action (e.g., restart the session with a fresh state). This guideline is documented in CLAUDE.md. During code reviews of TypeScript files under packages/core/src, ensure changes are staged as non-destructive, include clear user prompts or upgrade paths, and avoid migrations that modify existing persisted data automatically.

Learning: In this repo’s TypeScript code, do not flag unannotated local `const` declarations as missing explicit type annotations. Type inference for local `const` is intentional and consistent; the lint rules enforced here cover `typescript-eslint/explicit-function-return-type` and `typescript-eslint/explicit-module-boundary-types` (and there is no `typescript-eslint/typedef`), and Biome likewise does not require explicit types for local `const`. For example, `const foo = process.platform !== 'win32'` should be accepted without adding a manual type annotation.

Learning: In tobyhede/rundown, `getRunbookFromState` (packages/cli/src/helpers/runbook-loader.ts) returns `readonly ResolvedStep[]`. `RunbookActorService.sendAndSync` (packages/core) takes a mutable `ResolvedStep[]`, so callers must spread the result (e.g. `[...steps]`) to satisfy the TS2345 type constraint. Do not flag this spread as unnecessary overhead — it is load-bearing for type safety.

Document the persisted prompted contract. CreateOptions.prompted is optional and defaults to false, but persisted RunbookState.prompted is required. load() rejects rows that omit it with reason: 'missing_prompted'; no read-site fallback exists.

Update the changeset documentation around the runExecutionLoop prompted fallback
to state that CreateOptions.prompted is optional and defaults to false, while
persisted RunbookState.prompted is required; document that load() rejects rows
missing it with reason 'missing_prompted' and that read sites do not apply a

… per run
The previous fix made the guard lint real files so ESLint and the TypeScript
checker read the same bytes, which is necessary — `lintText` against a borrowed
`filePath` served the AST out of a watch program keyed by path with nothing
reconciling the two, and that is what failed in CI while passing locally. It
wrote them into `packages/core/src/runbook/` and swept them afterwards, which is
not sufficient: a transient real file in a real package is visible to everything
else that reads the working tree while it exists.
Three consequences, none of them theoretical:
- `src/**` is inside the Stryker `mutate` glob, and
`scripts/mutation-shard-plan.mjs` globs the filesystem — not `git ls-files`, so
`.gitignore` did not hide them — then `readFileSync`s every hit with no guard.
`scripts/__tests__/mutation-sharding.test.mjs` drives that real planner at the
repo root, in parallel, because `node --test` parallelises test files. A probe
fixture was planned as its own mutation scope; against a churn loop, 21 of 25
planner runs died `ENOENT` between the glob and the read. One write/sweep makes
that window narrow, not absent.
- `src/**` is also inside `packages/core/tsconfig.json`'s build `include`, so a
concurrent `tsc` emitted fixture output into `dist/`.
- They are deliberate lint violations while they exist, so an editor's ESLint
watcher or a hand-run `check:lint:typed` in that window reported errors that
were about to stop existing.
The fixtures are now committed under `packages/core/__tests__/fixtures/brand-cast/`.
Outside `src`, they are outside both the mutate glob and the build include; being
permanent, there is no window at all. `packages/core/__tests__` is still inside
`tsconfig.eslint.json`'s `include` and still lands in the `**/*.ts` block that
sets the ban, and the relative import still reaches the real producer, so the
checker resolves the same symbol a production cast would name.
What committing costs is that ten deliberate violations would fail the repository
lint gate forever, so the directory is listed in `eslint.ignores.js` and
re-included by the test with `new ESLint({ ignore: false })`. That option
overrides file SELECTION only — the rule configuration those paths resolve is the
real config, unmodified. Two new assertions keep both halves honest: one pins the
ignore entry (deleting it would redden `check:lint:typed` permanently while every
other assertion here stayed green), and one resolves the configured severity
directly for a production core module and for the exempted producer, which is the
property the old fixture location stood in for.
`union-member.ts` asserted to `RenderedUnitCommand | never`, which TypeScript
normalises back to `RenderedUnitCommand` before the checker sees it — so that case
was a duplicate of `direct-as.ts` and exercised no union code. Deleting the rule's
union-descent branch failed nothing. It asserts to `| undefined` now, and that
mutation is killed. Three other targeted mutations of the rule (dropping the
`TSTypeAssertion` visitor, the base-type walk, and the brand identity) each fail
exactly the cases they should and nothing else.
Also adds a fixture-inventory assertion, so a fixture nobody lints cannot sit
there reading as coverage.

Learning: In this repo’s TypeScript code, do not flag unannotated local `const` declarations as missing explicit type annotations. Type inference for local `const` is intentional and consistent; the lint rules enforced here cover `typescript-eslint/explicit-function-return-type` and `typescript-eslint/explicit-module-boundary-types` (and there is no `typescript-eslint/typedef`), and Biome likewise does not require explicit types for local `const`. For example, `const foo = process.platform !== 'win32'` should be accepted without adding a manual type annotation.

Document and type each exported fixture value.
Each forged export lacks TSDoc and relies on inferred exported types. Add a short TSDoc description and an explicit declared type without removing the deliberate assertion.

Source: Coding guidelines
Core's non-test `__tests__` files document their exports voluntarily — the lint rule is off there (`jsdoc/require-jsdoc` resolves to 0 for the directory), but `bearer-factory-fixtures.ts` and `entry-seam-barrel.typecheck.ts` both carry TSDoc, and the latter is the closest analogue: another compile-time guard file whose exports exist only to be checked. These fixtures were the outlier at zero. Each line carries the fact that distinguishes that fixture from its siblings rather than restating the identifier, so the set reads as a list of laundering routes when skimmed. The control's three exports say what must NOT happen, which is the only thing an undocumented negative control cannot tell you. No fixture body changes, so the assertion under test is untouched.

Closes #817. Closes #819. Closes #820. Part of #799.
Follows #826, which landed the #816 characterisation this PR flips.
The defect
Two functions built the
StepEntryMetadatabehind aSTEP_ENTEREDpayload andthey disagreed. The CLI execution loop rendered
description,prompt,commandCodeandcommandLang; core's collection service filled ids, position,name and flags and left every rendered field absent. All four are optional on
the type, which is what let the disagreement compile.
Observable: substep
1.1entered viarundown runcarried its description;entered via
rundown collectit carried none.What changed
#817 —
runExecutionLoopreadspromptedoff the run. Every one of its sixcall sites passed the run's own persisted flag, so the parameter was only a way
for a caller to disagree with state about a fact state owns.
LifecycleLoopDirective.promptedwent with it.#819 — one core seam for entering a unit.
RunbookActorService.enterExecutionUnit({ state, steps })renders, observes andclassifies, returning
awaiting | runnable | inline-launch. The loop sendsstate and steps and reads back a classified entry; it renders nothing. That
replaces its use of an undefined rendered-command field as a control-flow
signal.
The command is one value: the string announced in
STEP_ENTERED.commandCodeand the string handed to
EXECUTE_COMMANDcome from one expansion, so anon-deterministic
--helpershelper cannot make a runbook run something otherthan what it announced. That was held by statement ordering; it is now held by
construction.
RenderedUnitCommandcarries a tier-1 phantom brand minted onlyin the producing module, with two ESLint rules making it load-bearing.
#820 — collect enters through that seam. The hand-built partial entry is
gone. All three #816 assertions flip: description/prompt present end to end,
promptedcomposed with the step kind,substepIdoff the resolved unit. Bothfrontier seams shed their
entryparameter,observeExecutionUnitEntryandderiveStepEnteredEffect's two cursor guards are deleted rather than leftunreachable, and the new render-failure surface gets its own code (RD-833)
instead of escaping as RD-999 "Unknown error".
Notable
second spelling of a fact the types already carried —
kind === 'command',kind === 'for', two redundant inline-intent identity checks, and atypeofguard an optional chain already answered.
Error,which meant a collect whose committed target carried an unparseable
stateValuereported "fix the helper and re-delegate" when the recovery isprune/restart. They raise
InvalidRunbookStateErrornow, so RD-309 fires.RD_WORK_PATHreads off the validated render context, closing a latentsplit where
FOR WorkPath IN …could give the child one work directory whilethe same entry announced artifact paths under another.
Verification
pnpm run verifygreen — 8710 tests, 334 suites.pnpm run test:mutate:changedover every changed range.execution-unit-entry.tsis 100% (98/98, no survivors, no timeouts).hand-applying the mutant: a static mutant jest's module registry defeats,
state.prompted ?? true(one productioncreatesite, required boolean), andthe loop's
&& falsesibling, which IS killed — by an integration test thescoped gate does not run.
goto-workflow,runbook-pipeline,transitionsandcollectsit on character-identical pre-existing expressions: removing the argument let
Biome reflow the call, pulling untouched lines into the diff-derived range.
Reviewed
/code-review highraised four findings. Three were valid and are fixed above;the fourth (a raw-vs-canonical
cwdsplit) was checked and is not reachable —the CLI always passes
process.cwd(), which Node returns already resolved.Summary by CodeRabbit
