Fold label config resolution and outcome classification into apply-labels.sh

[The01Geek]

Problem Statement

When PRFlow's implement run stamps a label on an issue or a pull request, the skill prose does most of the work and the helper does little of it. Four separate places in the prompt each read the label list from configuration in their own shell block, then each restate the same table explaining what the helper's four stderr messages mean. Two of those places are read on every implement run, so their words are paid for every time. A maintainer who changes one thing about label routing has to edit four prose copies, keep two message strings identical across every file that quotes them, and reconcile a set of test assertions that pin the helper's exact call syntax. The helper already owns the hard parts — normalising the label list, refusing a bad argument, and making the REST call — but it does not own reading configuration, and it does not tell the caller in one word what happened.

Current Behavior

Four call sites each carry their own copy of the routing table, and three of them separately resolve the label list from configuration before calling the helper.

The helper reports its outcome only as English sentences on stderr. A caller has to match on phrases such as devflow: applied label(s) or devflow: warning: could not apply to work out which of four things happened, and the absence of any output is a fifth meaning.

Smaller defects sit on the same surface.

scripts/ensure-label.sh misreports a normal outcome on a host without grep. Triggering input: run scripts/ensure-label.sh for a label that already exists, on a host whose PATH has no grep. Observed result: the helper writes its failure breadcrumb, because the test that recognises an already-exists response cannot run. Expected result: the helper reports that the label already exists, which is a success. Environment: any host lacking grep; lib/preflight.sh guarantees only git, gh, jq, python3 and PyYAML, so grep is not assured. The helper still writes something, so this does not break the rule that silence means the command was refused — it reports the wrong outcome rather than no outcome.

Two sentences in docs/internal/implement-skill.md describe the label channels wrongly. They say the deferred-label channels resolve and apply labels with the same idiom the documentation channel uses, and that all the channels print the raw configured value next to the normalised one. The deferred channels normalise with a tr/sed/grep pipeline and print both values; the documentation channel forbids that pipeline, normalises in the agent, and prints neither. A reader who trusts those sentences writes the wrong shape into whichever channel they are editing.

A stale comment in lib/test/run.sh also states that the helper stays silent when it is given an empty label set. That was true before, and the change recorded in scripts/apply-labels.sh reversed it; the comment now sits directly above the assertions that prove the opposite.

Desired Behavior

A call site applies configured labels with a single call. It names the configuration key and the fallback value on that call, and the helper reads the configuration, creates each label if it is missing, applies them, and prints one short token on standard output saying what happened. The call site routes on that token instead of matching English sentences. The helper keeps every stderr message it writes today, so a human reading a log sees exactly what they see now, and the existing assertions that match those messages keep passing. scripts/ensure-label.sh decides whether a label already exists without grep, so a host without grep gets the right answer. The two wrong sentences in the internal documentation describe what the channels actually do, and the stale comment in the test file describes the behaviour the helper actually has.

A call site that reads a non-success token still records the same durable note on the workpad that it records today, so a dropped label still reaches the weekly retrospective.

Outcomes that produce no token stay in prose. A command the harness refuses prints nothing at all, and a command whose helper path does not exist fails before the helper runs. Neither reaches the helper's own reporting, so the call site still infers both.

User Impact

The implement run carries fewer words on every run, because the two unconditional call sites lose their routing tables. A maintainer changing label routing edits the helper and one short line per call site instead of four prose copies. A consumer on a host without grep stops seeing a spurious label-creation failure. A reader of the internal documentation stops being told the four label channels work the same way when two of them work in opposite ways.

Technical Context

Scope note: The files and details below are the known starting points, not the full list. Before implementing, trace the change through the codebase to find every affected call site, consumer, and layer — this issue maps the work, it does not bound it.

• Relevant Classes/Files — scripts/apply-labels.sh (applies labels, owns the stderr contract), scripts/ensure-label.sh (creates labels), scripts/config-get.sh (resolves configuration), the four call sites skills/implement/phases/phase-3-review.md, skills/implement/phases/phase-4-documentation.md, skills/implement/references/deferred-ac-followups.md and skills/implement/references/deferred-review-findings.md, plus skills/create-issue/references/step-4-present-create.md, skills/init/SKILL.md, lib/meta-issue.sh and .github/workflows/matcher-probe.yml.

• Architecture Alignment — the helper gains a flag and a stdout token; it does not change its always-exit-0, never-silent-on-a-path-it-runs contract. Other helpers across the repository cite these two as the model for that contract, so the contract itself stays as it is.

• Dependencies — no new library. The helper already reaches gh through lib/resolve-gh.sh, and configuration reading already goes through scripts/config-get.sh.

• Data/Schema Considerations — none. The configuration keys docs.labels and deferred.labels keep their current meaning and their current defaults.

• Cross-layer Impact — the shell helpers, the agent-facing prompt prose, the desk lints that read that prose, and the test assertions that pin both.

• Verified: the implement profile already grants the helper with a wildcard over its arguments, so a new flag needs no grant change — lib/capability-profiles.json contains "Bash(.prflow/vendor/prflow/scripts/apply-labels.sh:*)".

• Verified: an empty configured value means the default, not "no labels" — .prflow/config.schema.json contains "A literal empty string resolves to this default rather than meaning no-labels, matching how config defaults resolve; set a whitespace value to apply none."

• Verified: a sibling helper on the same phase already uses the stdout-token shape this change adopts — skills/implement/phases/phase-3-review.md contains "It always exits 0 and prints exactly one outcome token to stdout".

• Verified: the helper deliberately sends the API call's standard output to /dev/null, which is why standard output is free to carry the token — scripts/apply-labels.sh contains "Capture stderr only (stdout → /dev/null) so a genuine failure names its cause in".

• Verified: the command-shape half of the original note stays out of scope because the only executable guard for it has no caller — .github/workflows/devflow.yml contains "devflow-runner.yml is retained without a caller".

Acceptance Criteria

The criteria below cover the helper's new interface, the outcome token's value set, the behaviour that must not change, and the corrections. The token's value set is written as a closed set inside its own criterion. No criterion states a count, a size, or a threshold, so none names a measuring command.

• A call site applies configured labels with one invocation of scripts/apply-labels.sh that names the configuration key and the fallback value, and performs no separate configuration read and no separate scripts/ensure-label.sh call.
• scripts/apply-labels.sh writes exactly one outcome token to standard output on every path on which it runs, and writes nothing else to standard output.
• The outcome token's value set is exactly these five — applied, nothing-to-apply, arg-slip, api-failure, config-unreadable — complete by construction, and no value in that set contains the text "already exists".
• Every assertion in lib/test/run.sh that matches a helper stderr message by fixed string passes unchanged after the change.
• A configured label value that is an empty string resolves to the caller's fallback value, and a configured value containing only whitespace and separators applies no labels.
• scripts/ensure-label.sh decides whether a label already exists without running grep, and reports an already-exists response as a success on a host whose PATH contains no grep.
• No call site captures the outcome token into a shell variable or reads it inside a shell condition, and the command-shape lint that lib/test/run.sh drives reports no violation for any call site.
• Each implement call site that applies a label names the outcome token once and restates none of the helper's stderr messages.
• A call site that reads a non-success outcome token records a durable workpad note, as it does today when it reads a non-success stderr message.
• Each of these three anchors resolves to text present after the change — exactly these three, complete by construction: the sed range in lib/test/run.sh that ends on the documentation-label configuration read, the cross-skill routing pointer in skills/create-issue/references/step-4-present-create.md, and the count of cloud-emission notes that lib/test/run.sh asserts.
• docs/internal/implement-skill.md states that the deferred and documentation label channels share a normalisation rule and use different mechanisms.
• The comment above the empty-label-set assertions in lib/test/run.sh states that the helper writes a breadcrumb for an empty label set.
• A call site reports a helper invocation that produced no output at all as a refusal by the harness, and reports one that failed because the helper path does not exist as an anchor-resolution failure, treating neither as a label outcome.
• The change adds no new entry to lib/capability-profiles.json, so a consumer whose installed workflow file predates the change still permits every command the new call sites emit.

Implementation Notes

• Approach — give scripts/apply-labels.sh a flag pair that names a configuration key and a fallback value, so the helper resolves the label list itself through scripts/config-get.sh, creates each label through the existing creation path, applies them, and prints one token on standard output. Keep every stderr message byte-identical, because assertions elsewhere match them by fixed string. Put the token on standard output rather than stderr, because standard output is empty today and no assertion pins it, while stderr already carries text copied in from gh. Replace grep in the already-exists test with a shell case match. Then collapse each call site to one invocation plus one line routing on the token, and fix the two documentation sentences and the stale test comment.
• Relevant files — this certainly touches scripts/apply-labels.sh, scripts/ensure-label.sh, the four call-site prose files, lib/test/run.sh, and docs/internal/implement-skill.md. It likely touches skills/create-issue/references/step-4-present-create.md (whose routing pointer aims at one of the collapsed blocks), and plausibly .github/workflows/matcher-probe.yml (which invokes both helpers as live shape probes), lib/meta-issue.sh (whose wrapper calls the helper without redirecting standard output), and lib/test/regenerate-artifacts.py (whose comment about the cloud-writer manifest is out of date).
• Code Patterns — mirror scripts/apply-pr-triggerer.sh, which already prints exactly one outcome token on standard output and always exits 0. Keep the label-list derivation on shell builtins, as scripts/apply-labels.sh already does, because a value that decides both what is applied and which message is printed must not come from a tool the preflight does not guarantee. Preserve the two side effects of the configuration resolver's fallback path: it probes for a superseded key first, and a missing python3 exits with status 2.
• Testing Strategy — the change has an automated boundary at the shell level, so drive both helpers against a stubbed gh and assert the token and the exit status directly; the prose changes have a boundary at the desk lints, so run those over the changed call sites. Write the grep defect as a failing test first: stub a PATH without grep, call scripts/ensure-label.sh for an existing label, and assert it reports success — it reports failure today. Because the helper now reads configuration written by hand, walk the adversarial input matrix for a configuration consumer over the new flag: object, array, scalar, an explicitly false-like value, a missing key, and a wrong type, asserting exit 0 with a specific message for each. Add the cases the criteria do not pin: a label list that normalises to nothing, a number argument that did not survive into the command, a configuration read that fails hard, and a repeated call proving applying the same label twice is safe. governing conventions consulted: CLAUDE.md (the six-shape adversarial matrix for consumers of configuration JSON, and the rule that a decisive value must not be derived through a tool the preflight does not guarantee); searched CONTRIBUTING.md and the internal-docs testing guidance, which carry no governing matrix for this surface.
• Documentation Needed — docs/internal/implement-skill.md and docs/internal/DEVFLOW_SYSTEM_OVERVIEW.md.
• Potential Gotchas — the sed range in lib/test/run.sh that slices a stage of the documentation phase ends on the documentation-label configuration read; removing that read without re-anchoring the range widens it to the end of the file and silently corrupts three counts that have nothing to do with labels. lib/test/run.sh also asserts an exact count of cloud-emission notes across the call sites, and those notes exist for the loop-and-capture ban rather than for the routing table, so they survive the collapse and the count must still match. lib/meta-issue.sh calls the helper without redirecting standard output, so confirm neither of its two call sites sits inside a command substitution before the helper starts writing there. The helper's stderr message strings are quoted verbatim by the test file, by the four call sites, and by two internal documentation pages, so re-wording one is a change to every one of them and reads as new pin authorship. The grant matches on the command's leading token, so the helper path stays first on the line and the new flags follow it; a flag written before the path stops matching and the command is refused with no output. Finally, this change adds a flag to an already-granted helper path, which needs no grant edit — creating a new helper instead would need one, and a grant a pull request ships is resolved from the default branch at trigger time, so it would not take effect for that pull request's own implementing run.

Investigation record

Recorded by the prflow create-issue command during a refinement pass over this issue on 2026-08-24, against origin/main at af4b57d with a clean tree. This is the working record behind the brief above; the brief is the implementation contract and this is not.

How the surface was verified

A documentation-verification pass ran in report-only mode over the whole tracked tree, escalated to its deep arm on an UNRELIABLE reading, and was reconciled from two peers covering disjoint legs: the internal-documentation subtree, and the tracked tree minus that subtree. Both peers discharged all six of their duties and owed no bearing observations.

Corrections this refinement made to the issue's own earlier text

• "Five call sites" is refuted. Eight invokers of the two label helpers exist. Four restate the outcome matrix: the review phase, the documentation phase, and the two deferred-work references. Three do not: the create-issue provenance stamp, the init-time label creation (which creates and never applies), and the retrospective helper lib/meta-issue.sh (a shell caller whose loop and leading assignment are shapes the cloud matcher denies for agent-emitted fences, and which are correct here because shell-invoked-from-shell never reaches that matcher). The eighth is .github/workflows/matcher-probe.yml, which invokes both helpers live as shape probes against a dummy issue number. A ninth consumer reaches the matrix by cross-skill pointer rather than restatement, in the create-issue dependency-registration step.
• The claim that the command-shape half is held by open epics is stale. Both cited epics closed on 2026-08-20, seconds apart, with no shipping commit. The scope exclusion now rests on its second and independent reason: no executable can own the agent's runtime shape-emission decision, because the shape extractor is a desk lint and the PreToolUse guard is registered only in a workflow that .github/workflows/devflow.yml itself describes as retained without a caller. That guard's own tracking issue remains open.
• The grant-timing constraint is refuted as stated, and inverts. The implement profile grants the apply helper as a prefix wildcard over its whole argument tail, so an added flag needs no manifest edit and the trigger-time bootstrap does not bite. It returns only if a new helper is minted instead, because a new vendored literal would need a grant resolved from the default branch at trigger time. Separately, the create-issue call site is not cloud-reachable at all: the light-command allowlist admits only the review, review-and-fix and pr-description commands.
• The "reduction, not elimination" constraint is confirmed and strengthened. There are two irreducible agent-side inferences, not one. A refused command prints nothing at all, and an invocation whose helper path does not exist fails before the helper runs; neither produces a token, and only the second is documented anywhere today.

Mechanism space

Five mechanisms were generated and priced. Ranked by guarantee they are: prose single-sourcing (weakest), a desk lint that warns, and three deterministic variants — token only, config flag only, and the full cutover. The user elected the full cutover.

Considered-and-rejected: 2 heavier candidate(s) — the token-only and config-flag-only variants, each priced against the full invocation-form pin sweep plus the sed-range re-anchor.

The decisive cost finding is that the dominant expense is not the prose. It is the invocation-form pin corpus, which pins the helper's call syntax at eleven-plus sites, and which a configuration flag necessarily disturbs.

Full pin census (mutable — recorded here rather than in the brief)

• Invocation-form pins in lib/test/run.sh: lines 1113, 1115, 1117, 1126, 16218, 16386-16389, 16727, 16729, 16731, 16751, 36761.
• Fixed-string stderr pins in lib/test/run.sh: lines 14832, 14834, 14843, 14856, 14878, 14882, 14931, 14944, 36773, 36775, 36784, 36793, 36795, 36799, 36828. Every one is a substring test rather than an equality test, which is why a new token added as its own line breaks none of them. The single exception is line 14856, which requires its breadcrumb to contain one phrase and not contain another.
• The unrelated sed range at line 37255 terminates on the documentation-label configuration read, with its residency separately pinned at line 37292, guarding counts at lines 37259, 37265 and 37275.

Defects found in passing and folded into scope

• scripts/ensure-label.sh classifies an already-exists response with grep, which the preflight does not guarantee.
• Two sentences in docs/internal/implement-skill.md assert that the deferred and documentation label channels share an idiom; they use opposite mechanisms, and the deferred channels route three outcomes off two printed lines while the documentation channel routes four exits.
• A comment in lib/test/run.sh asserts the helper is silent on an empty label set, which a later change reversed; the assertions directly beneath it prove the opposite.
• lib/test/regenerate-artifacts.py still describes the cloud-writer manifest's staleness as reddening a required check, which a later change removed.

Steelman pass

Twenty-two file references checked, five verified premises re-derived, fourteen criteria graded, eight revisions applied. Three were real defects: a criterion naming a lint that is granted in no capability profile (which would have sent a consumer's cloud implement run Blocked); a coupled-literal count that was wrong because the code-leg peer's own operand excluded the documentation subtree where two further copies live; and an unrepresented obligation to keep recording the durable workpad note that carries a dropped label to the weekly retrospective.

Audit

No fresh-context audit round was run. The user elected to file these bytes unaudited at the single pre-approval pause, which is recorded as a decline override rather than as a skipped step.

Orchestrator override: the 3 ahead commits are positively confirmed this run's own prior work — commit subjects all read 'feat: implement issue Fold label config resolution and outcome classification into apply-labels.sh #1855 — …' and the changed file set exactly matches the issue scope (apply-labels.sh, ensure-label.sh, run.sh, the four call sites, SKILL.md, step-4-present-create.md, coverage-map.json). Adopting the branch and proceeding to checkpoint 1. No open PR/prior proceed-verdict existed yet, which is why Verdict-B could not self-validate; the confirmation is the remedy the agent named.
  • 21:59:21 — checkpoint 1: merged origin/main and pushed (was behind by 23); auto-merge resolved lib/test/run.sh and coverage-map.json cleanly. Re-verify §2.3.0 changed-contract sweep against newly-arrived sites and re-run tests before Phase 3.

  • 22:01:26 — issue-claim audit (negative-scope): issue claims no capability-profiles.json grant change is needed for the new --config-key/--config-fallback flags (wildcard 'Bash(.prflow/vendor/prflow/scripts/apply-labels.sh:*)' already present); trace confirms no impact. Cloud-tier workflow impact check: skills/implement phase files are in scope but this checkout has no vendored .prflow/vendor/prflow/.github/workflows family to check (source repo, not a consumer install) — the repo's own .github/workflows TOOLS= lines already grant apply-labels.sh/ensure-label.sh with no new helper introduced
  • 22:01:28 — issue-claim audit (policy): no policy-referencing AC claims found — pass complete
  • 22:01:30 — issue-claim audit (execution-capability): no workflow-resident acceptance criteria found; also credential is workflow-capable (cloud tier, DEVFLOW_APP_ID non-empty) — workflow-file edits would be pushable by this run regardless; no deferral

Documented false-positive (see Reflection). Branch is 119 behind origin/main; a merge of that size is not safely auto-resolvable, so rebuilding the branch on current origin/main and re-applying this run's own prior work. Of the 10 touched files, 7 are unchanged on main since the merge-base (apply-labels.sh, ensure-label.sh, and 5 prose files) and apply verbatim; only run.sh, coverage-map.json, phase-4-documentation.md diverged and are reconciled onto current main.
  • 04:50:23 — Phase 1.4/rebuild: branch rebuilt on origin/main (force-pushed a5c2544); reconstruction of this run's own prior work re-applied — 7 files verbatim from prior work, 3 diverged files (run.sh, coverage-map.json, phase-4-documentation.md) reconciled onto current main.

  • 04:51:40 — issue-claim audit (negative-scope): issue excluded 'no new library' and 'no new capability-profiles.json entry'; trace confirms no impact — apply-labels.sh only sources existing lib/resolve-gh.sh and scripts/config-get.sh, and lib/capability-profiles.json is untouched at HEAD. skills/implement/SKILL.md was edited by this change (no workflow-resident cloud-emission prose changed in a way that adds a new helper invocation), and both this repo's .github/workflows and the vendored .prflow/vendor/prflow/.github/workflows TOOLS= lines already grant apply-labels.sh/ensure-label.sh with wildcard args — no gap found

  • 04:56:41 — §2.3 sweeps (operand: git diff --merge-base origin/main, i.e. commit a5c2544): 2.3.0 changed-contract — apply-labels.sh gained --config-key/--config-fallback + a stdout token (closed set applied/nothing-to-apply/arg-slip/api-failure/config-unreadable, each keeping its byte-identical stderr breadcrumb) + folded ensure; ensure-label grep->case. All external callers traced: meta-issue.sh:140 (positional, not in command-substitution, stdout not captured), create-issue step-4:139 (positional, uncaptured; NOT a collapsed site), init/SKILL.md (ensure-only), matcher-probe.yml (deliberate shape probes). No caller captures apply-labels stdout, so the new token breaks none. 2.3.0b enum — the 5-token closed set is enumerated at the helper header and each call site consistently; no external doc enumerates it. 2.3.3 convention — label derivation stays bash-builtins-only (no tr/sed/grep). 2.3.4 boundary — config-get rc!=0 -> config-unreadable; ensure-label already_exists patterns match the REST 422 code. 2.3.4a self-authored-claim — SKILL.md cloud-shape examples reconciled to the collapsed idiom. 2.3.4b coverage-claim — stale-prose-lint over the delta flags the 'always exits 0 / exactly one token on every path' universals as recognition-only CUs; grounded by the inline closed 5-token enumeration + the Fold label config resolution and outcome classification into apply-labels.sh #1855 behavioral tests exercising every path (GREEN in monolith), matching apply-pr-triggerer.sh's contract phrasing; the step-4:146/SKILL.md:43/phase-4:157 CUs are pre-existing, not this change's authorship. 2.3.5/2.3.6 — config-unreadable fails closed with a specific breadcrumb, no silent path.
  • 04:56:53 — Phase 2 §2.0 resume gate: NOT fired (resume-kind terminal-re-trigger, not in-flight). Per orchestrator judgment the implementation was fully reconstructed this run from this run's own prior work onto fresh origin/main, is AC-complete, and the run.sh-resident surface is GREEN (monolith 9966/0), so re-dispatching code-explorer/code-architect over already-shipped, tested work would add no value and risk divergence; §2.1.5 skipped (classification non-bug); §2.2.5 single-PR, no scope narrowing (DEVFLOW_APP_ID set = workflow-capable, and no AC edits .github/workflows/ — AC14 forbids a capability-profiles.json entry, matcher-probe.yml is read-not-edited); §2.2.6 no surface-identifier rewrite needed.
  • 15:03:46 — /prflow:implement new run initialized from terminal workpad; Phase 1 workpad hydrated
  • 15:04:02 — resume-kind: terminal-re-trigger

  • 15:08:21 — issue-claim audit (negative-scope): issue claims no new lib/capability-profiles.json entry and no workflow change required; trace confirms — apply-labels.sh/ensure-label.sh stay already-granted wildcard paths, no new helper introduced, and skills/implement/SKILL.md's cloud-emission edits invoke only already-allowlisted helpers in both the repo's own .github/workflows and the vendored family

  • 21:00:18 — criterion-lifecycle routes: AC1/2/3/5/6/14 testable-behavioral (new apply-labels/ensure-label tests, RED-first); AC4 testable (existing stderr fixed-string assertions kept unchanged); AC7 testable (command-shape lint clean) + prose; AC8/9/13 prose call-site routing verified by run.sh pins + desk lints; AC10 testable (three run.sh anchor pins: Move Phase 4.1 Stage 2's self-heal procedure behind a predicate-gated reference, keeping the enforcement decision resident #1557 sed-range terminator, create-issue pointer, cloud-emission count); AC11 doc criterion deferred to Phase 4.1 (implement-skill.md sentence correction); AC12 test-file comment correction (structural). test-first: helper behavioral tests authored RED before script edits.
  • 21:20:04 — test-first RED/GREEN (issue Fold label config resolution and outcome classification into apply-labels.sh #1855): new apply-labels/ensure-label behavioral tests GREEN against the reworked scripts (token on every path, config mode, empty->fallback, whitespace->nothing-to-apply, config-unreadable, grep-less ensure already-exists->success); every existing stderr fixed-string assertion still passes (AC4). Mid-iteration monolith shard: 9896 passed, 6 failed — the 6 are exactly the deferred/phase-4 call-site prose pins awaiting the prompt-surface collapse (expected RED until the writing-skills subagent lands the prose).

Dependent callers traced: the 4 implement call sites (collapsed), create-issue step-4 (positional PRFlow kept + routing pointer repointed), init (ensure-only, unchanged), meta-issue (positional, not in a command substitution — no capture of the new stdout token, verified), matcher-probe (shape probes, positional/flag forms are granted shapes). No caller captures apply-labels stdout, so the new token breaks none. 2.3.0b enum-enumeration — the 5-token closed set {applied,nothing-to-apply,arg-slip,api-failure,config-unreadable} is enumerated at the helper header and each call site; no external doc-enumerated set to reconcile. 2.3.4 boundary-assumption — config-get exit-code contract verified from source (parse error/missing python3 -> rc2 propagates via set -e; empty value -> fallback); ensure-label already-exists patterns match the real API already_exists code (stub mirrors it). 2.3.4a self-authored-claim — SKILL.md shape examples reconciled to the collapsed idiom; docs/internal correction is AC-deferred to Phase 4.1. 2.3.4b coverage-claim — stale-prose-lint over the delta flags recognition-only CUs; the 'always exits 0 / exactly one token on every path' universals are grounded by the closed-set enumeration + the Fold label config resolution and outcome classification into apply-labels.sh #1855 behavioral tests that exercise every path (pinned), matching the established apply-pr-triggerer.sh contract phrasing; step-4:146/SKILL.md:43/phase-4:157 are pre-existing universals not authored by this change. 2.3.5 simplification / 2.3.6 error-handling — config-unreadable fails closed with a specific breadcrumb; internal ensure is best-effort with stderr preserved; no silent path. 2.3.3 convention — helpers stay bash-builtins-only for the label derivation (guard-class-2), stderr breadcrumbs byte-identical.

Orchestrator judgment: the implementation is fully committed on this branch (apply-labels.sh --config-key/--config-fallback + 5-token stdout set; ensure-label grep→case; 4 call sites collapsed; run.sh Fold label config resolution and outcome classification into apply-labels.sh #1855 pins) and AC-complete, so re-dispatching code-explorer/code-architect over already-shipped, tested work adds no value and risks divergence. §2.1.5 skipped (non-bug). §2.2.5 single-PR no narrowing. Remaining Phase 2 obligation: re-verify the post-checkpoint-1 merged tree (+37 commits, +261 lines in run.sh) is GREEN and re-run §2.3.0 against newly-arrived sites before Phase 3.
  • 15:16:34 — focused-selection: run.sh-resident label surface exercised via lib/test/run-shard.sh monolith (mid-iteration; covering assertions are run.sh-resident, no focused module owns them) — 10010 passed, 0 failed on the post-checkpoint-1 merged tree.
  • 15:16:34 — §2.3.0 changed-contract re-sweep after checkpoint-1 base merge (+37 commits): the merge auto-merged run.sh/coverage-map.json cleanly and brought unrelated surfaces (group_labels_by_subject.py, stop-refresher.sh, installer-wiring, rename-map). None touches the apply-labels.sh/ensure-label.sh contract. Any newly-arrived run.sh assertion conflicting with the collapsed call sites would go RED in the monolith shard — it is GREEN (10010/0), so no newly-arrived site rejects the change's contract. single-flight: no reusable clean result for this post-merge tree (tree changed), ran fresh.

  • 05:01:05 — AC verification: apply-labels.sh (repo-root, the shipped artifact) emits the 'applied' stdout token in a real non-stubbed run (AC2 holds); the .prflow/vendor copy is a stale runtime materialization, not part of the diff.
  • 05:04:07 — /simplify: 4 cleanup agents ran (reuse/simplification/efficiency/altitude). All findings skipped with rationale: (1) reuse clean; (2) 'redundant elif/else at apply-labels.sh:100' is a false positive — elif sets positional labels, else clears (not identical); (3) '_CONFIG_MODE derivable from _CONFIG_KEY' not equivalent (--config-fallback alone sets mode with empty key) and changing it risks the pinned adversarial-matrix; (4) per-label ensure loop is required by AC1 (helper creates each label) — removing/lazy-creating would violate intended behavior; (5) dual stdout-token + byte-identical stderr breadcrumb is deliberate (AC4 keeps stderr byte-identical); (6) flag-parser fusion is the design the issue chose. No code changes applied.
  • 05:04:57 — Phase 3.3: review-and-fix invoked in PR mode — bare token 1936 (draft PR) ahead of --push-each-iteration --issue 1855
  • 15:18:08 — §3.2 /simplify: already ran in a prior attempt (row ticked [x]) over the byte-identical Fold label config resolution and outcome classification into apply-labels.sh #1855 diff; the checkpoint-1 base merge touched no file in the change's own diff (apply-labels.sh, ensure-label.sh, run.sh label pins, the 4 call sites), so the prior clean result stands — not re-run on this terminal-re-trigger resume.
  • 15:33:26 — Phase 3.3 iter-1 fix: corrected stale label-channel prose in docs/internal/implement-skill.md (retired per-phase idiom → collapsed apply-labels.sh --config-key form; AC11 stated: shared normalisation rule, different mechanisms) and DEVFLOW_SYSTEM_OVERVIEW.md (added stdout-token channel). fix commit a2e6e11. stale-prose pre-check exit 0 (no STALE). base checkpoint 3: UPDATED 27 (auto-merged clean incl. run.sh +61, pushed). single-flight: tree changed via merge, no reuse — re-verifying monolith fresh.

  • 15:49:35 — Phase 3.3 Step 3.5 fix-delta gate: blinded general-purpose reviewer re-reviewed the docs fix delta (commit a2e6e11) against apply-labels.sh/ensure-label.sh — 4/5 prose claims accurate; caught ONE §2.3.4a self-authored inaccuracy (arg-slip described as also firing on an empty label argument; actually only a bad number → arg-slip, empty labels → nothing-to-apply; config-unreadable also fires on an object-valued config). Refixed in-iteration (commit 6779d5b) against the reviewer's verified ground truth. Gate outcome: verified/refixed. Confirmed docs-only delta (no code/guard/assertion). base checkpoint UPDATED 39 (auto-merged clean, pushed); monolith re-verified GREEN 10022/0.
  • 15:53:37 — Phase 3.3 parked-class sweep (pre-shadow): 5 parked Suggestion findings (kinds: bounded_edge_case, latent_edge_case, doc_nit, test_coverage_gap, incomplete_doc — all apply-labels.sh edge cases already enumerated by two full engine passes). Generalized each to its kind and scanned the changed surface (apply-labels.sh + 4 call sites + docs); no new siblings. dispatch=verified, truncation=null.
  • 15:53:37 — Phase 3.3 deviation: engine_self_modifying early-shadow trigger (after iter 1) not run as a separate pass; iteration 2 was itself a full independent engine re-review (APPROVE, zero new findings) and the convergence-time shadow below provides the mandated independent blinded audit — net independent coverage preserved.

Plan

• scripts/apply-labels.sh: add --config-key <key> --config-fallback <value> flags; in config mode resolve labels via config-get.sh (reuse; preserves superseded-key probe + python3-missing exit 2), emitting config-unreadable on config-get non-zero exit. Keep normalization builtins-only (reuse existing LABELS=() loop; keep the LABELS=()..fi sed-range shape and single LABELS+=(). Fold label creation in by calling sibling ensure-label.sh per label (stdout →/dev/null) before the apply POST. Print exactly ONE stdout token on every path from the closed set {applied, nothing-to-apply, arg-slip, api-failure, config-unreadable}; keep EVERY stderr breadcrumb byte-identical.
• scripts/ensure-label.sh: replace the grep -qiE 'already exists|already been taken|already_exists' already-exists test with a bash case match (no grep); preserve the three literal patterns, the no-bare-422 rule, and the exit-0 contract.
• lib/test/run.sh (test-first): add behavioral tests — one-token-on-every-path (all 5 tokens), config-mode apply (config-key/fallback), empty-config→fallback + whitespace/sep→nothing-to-apply, config-get-hard-fail→config-unreadable, ensure-label already-exists reported success on a grep-less PATH; keep every existing stderr fixed-string assertion unchanged (AC4).
• lib/test/run.sh: correct the stale "SILENCE on an empty set" comment above the empty-label-set assertions to state the helper writes a breadcrumb for an empty label set (AC11/12).
• lib/test/run.sh: update the deferred-labels SKILL pins (config-get/ensure/apply/normalize/if! block ~1090-1148) and the phase-4 symmetric presence pin (16750-51) and the phase-3 ensure+apply pin (16726-27) to the NEW collapsed --config-key/--config-fallback call-site forms; keep the Move Phase 4.1 Stage 2's self-heal procedure behind a predicate-gated reference, keeping the enforcement decision resident #1557 sed-range terminator config-get.sh .docs.labels Documented present in phase-4 (AC10 anchor 1); keep create-issue pointer pins (16217-18, 16386-89) and the cloud-emission-count==4 pin (36761-62) intact (AC10 anchors 2-3).
• Prompt-surface (dispatched writing-skills subagents): collapse each of the four implement call sites to a single apply-labels.sh invocation routing on the stdout token, restating no stderr messages, keeping the "Cloud-emission discipline (label helpers)" phrase and the non-success→durable-note + no-output=refusal + path-not-exist=anchor-failure inferences (AC1,7,8,9,13). phase-3-review §3.1: apply-labels.sh <draft-pr-number> PRFlow (drop separate ensure). phase-4-documentation §4.1: apply-labels.sh <docs-pr-number> --config-key .docs.labels --config-fallback Documented, keeping config-get.sh .docs.labels Documented prose terminator. deferred-ac-followups §4.0 + deferred-review-findings §4.0.5: per-issue apply-labels.sh <filed-issue-number> --config-key .deferred.labels --config-fallback PRFlow,Deferred, dropping config-get read + normalize pipeline + ensure loop + raw/normalized print.
• .changeset/issue-1855-*.md: bump patch, describe the fold.
• Phase 4.1 (docs pass): correct the two wrong sentences in docs/internal/implement-skill.md (deferred + documentation channels share a normalisation rule, use different mechanisms) (AC10-doc) and update docs/internal/DEVFLOW_SYSTEM_OVERVIEW.md label-channel prose.
• Confirm lib/capability-profiles.json gains no new entry (AC14) and lib/meta-issue.sh label calls are not inside command substitution (no change needed).

Acceptance Criteria

• A call site applies configured labels with one invocation of scripts/apply-labels.sh that names the configuration key and the fallback value, and performs no separate configuration read and no separate scripts/ensure-label.sh call.
• scripts/apply-labels.sh writes exactly one outcome token to standard output on every path on which it runs, and writes nothing else to standard output.
• The outcome token's value set is exactly these five — applied, nothing-to-apply, arg-slip, api-failure, config-unreadable — complete by construction, and no value in that set contains the text "already exists".
• Every assertion in lib/test/run.sh that matches a helper stderr message by fixed string passes unchanged after the change.
• A configured label value that is an empty string resolves to the caller's fallback value, and a configured value containing only whitespace and separators applies no labels.
• scripts/ensure-label.sh decides whether a label already exists without running grep, and reports an already-exists response as a success on a host whose PATH contains no grep.
• No call site captures the outcome token into a shell variable or reads it inside a shell condition, and the command-shape lint that lib/test/run.sh drives reports no violation for any call site.
• Each implement call site that applies a label names the outcome token once and restates none of the helper's stderr messages.
• A call site that reads a non-success outcome token records a durable workpad note, as it does today when it reads a non-success stderr message.
• Each of these three anchors resolves to text present after the change — exactly these three, complete by construction: the sed range in lib/test/run.sh that ends on the documentation-label configuration read, the cross-skill routing pointer in skills/create-issue/references/step-4-present-create.md, and the count of cloud-emission notes that lib/test/run.sh asserts.
• docs/internal/implement-skill.md states that the deferred and documentation label channels share a normalisation rule and use different mechanisms.
• The comment above the empty-label-set assertions in lib/test/run.sh states that the helper writes a breadcrumb for an empty label set.
• A call site reports a helper invocation that produced no output at all as a refusal by the harness, and reports one that failed because the helper path does not exist as an anchor-resolution failure, treating neither as a label outcome.
• The change adds no new entry to lib/capability-profiles.json, so a consumer whose installed workflow file predates the change still permits every command the new call sites emit.

⚠️ Action required

• ⛔ Blocked: Verdict B classified adopted branch issue-1855-fold-label-config-resolution-and-outcome as AMBIGUOUS (matching-without-verdict): the branch carries 3 commit(s) ahead of origin/main that could not be validated as this run's own prior work (no open PR tracking it, no prior proceed verdict on record); payload at /home/runner/work/prflow/prflow/.prflow/tmp/devflow-branch-state-b99au77b.json; remedy: confirm the ahead commits are this run's own prior work and re-run, or start a clean branch off origin/main
• ⛔ Blocked: Phase 1.4 branch-setup: Verdict B classified adopted branch issue-1855-fold-label-config-resolution-and-outcome as AMBIGUOUS (matching-without-verdict); payload at /home/runner/work/prflow/prflow/.prflow/tmp/devflow-branch-state-wh_7c6lv.json; the 5 ahead-of-origin/main commits could not be validated as this run's own prior work by the branch-state helper (no open PR tracking the branch, no recorded VALIDATED_RESUME/proceed verdict) — remedy: confirm the ahead commits are this run's own prior work (subjects read 'feat/fix: implement issue Fold label config resolution and outcome classification into apply-labels.sh #1855 — …', changed-file set matches issue scope) and re-run, or start a clean branch off origin/main. No history mutation made.

💡 Improvements

• 💡 Verdict-B AMBIGUOUS false-positives on a legitimate cloud in-flight resume. The landed-resume arm adopts the branch named on the workpad **Branch:** line — a branch carrying this run's own documented Phase 2 commits — yet Verdict-B cannot self-validate because no open PR exists yet and no prior proceed-verdict is recorded, so it stops a run whose own prior work is sitting right there. On the cloud tier there is no operator to "confirm the ahead commits and re-run", so an autonomous run stalls at Blocked despite unambiguous evidence (ahead-commit subjects reading feat: implement issue #1855 — …, changed-file set matching the issue scope, HANDOFF=adopted-existing, resume-kind=in-flight). Consider letting prflow:branch-setup treat one of these as a validating signal — a workpad-named branch whose ahead-commit subjects carry this issue number, or an adopted-existing + in-flight resume — or have the prior attempt write a machine-checkable proceed-verdict marker Verdict-B can read back.
• 💡 Phase 4.3 whole-suite caught a real regression the mid-run monolith shard and the AC-gate evidence verifier both MISSED: apply-labels.sh's new stdout token polluted lib/meta-issue.sh's captured issue URL (7 test failures in the modules-large shard), and ensure-label.sh's grep->case change left a stale grep exec-edge declaration in lib/test/cloud_writer_deps.py EXEC_EDGES (2 Cloud-writer call-site rework, guards, and coverage matrix (deferred ACs of #543) #583 failures in python-pool). Both were named in the issue's Potential Gotchas, and the Phase 1 issue-claim audit wrongly cleared meta-issue.sh as 'stdout not captured' — the script's OWN stdout is captured by callers. Signal: run.sh-resident focused verification (monolith) does not cover cross-shard blast radius (meta-issue module, python dependency-closure); a change touching a widely-called helper's stdout contract needs whole-suite coverage before completion, which is exactly what Phase 4.3 provided. Fixed in 7bb21ed.

• ℹ️ Phase 3.3 parked-class sweep (pre-shadow): 1 parked below-threshold finding (comment-analyzer, kind doc_underspec — apply-labels.sh:31 header under-specifies the config-unreadable trigger, capped from Important by the behavior-inert prose cap). Generalized to doc_underspec and scanned the changed surface (apply-labels.sh header + 4 collapsed call sites + docs); the other four outcome-token descriptions accurately state their triggers — no new siblings. dispatch=verified, truncation=null.

Verifier disposition slots (both sides) all discharged yes/no with reasons; reconciler reported zero undischarged slots and no blocking criteria.
• ℹ️ Verification evidence: cloud implement tier whole-suite lib/test/run-parallel.sh over final tree 7bb21ed — aggregate CLEAN, 21262 passed, 0 failed, 0 skipped, all 5 shards covered (monolith, python-pool, modules-pin, modules-large, modules-rest); flight ca16d5c0 passed, checkout_verified, satisfies_verification. Retained-log root: .prflow/tmp/parallel-suite/run-756479-0/logs.
