Resolves #16988

A unit test reported dev as red when dev was green. The failure came from a symlink on the developer's machine, and it named a repo path, so it read as a broken suite.

Evidence: L2 (the predicate proven across all three filesystem states, plus a full-suite run before and after) → L2 required (test-environment precondition; no production surface). No residuals.

What happened

Answering whether dev was red after five merges landed inside ~15 minutes, a full unit run against dev HEAD 10a29b1a79 gave 12856 passed, 1 failed:

Error: ENOENT: no such file or directory, open '<repo>/ai/deploy/.env'
  at deploymentPrescriptionEnvironment.spec.mjs:131  fs.writeFileSync(envPath, content)

ENOENT on a write means the parent is missing — but ai/deploy/ plainly exists. The path is a symlink to a per-operator prescription store outside the repo, and that store had been removed:

ai/deploy/.env -> ~/.neo-ai/deployment-prescriptions/active.env   (target absent)

fs.existsSync follows symlinks, so the dangling link reads as absent. The test's own preserve-and-restore is defeated on its own terms: it records "nothing to back up", then writes through a link that resolves nowhere.

ai/deploy/.env is untracked and gitignored (.gitignore:113), so CI never carries it — the red is unreproducible anywhere but the affected machine. That is what made it expensive: a full-suite run plus a tracked-vs-untracked check to attribute, during an incident where the operator had already merged overruling what CI appeared to say.

Deltas

The file already models this exact class one line above — test.skip(!composeConfigAvailable(), …). The symlink case joins it:

function danglingEnvSymlink(envPath) {
    return fs.lstatSync(envPath, {throwIfNoEntry: false})?.isSymbolicLink() === true && !fs.existsSync(envPath)
}

lstatSync is the whole distinction: it describes the link, never its target. throwIfNoEntry: false keeps a genuinely absent path from throwing, so the clean case stays on the running side.

The skip message names the machine state — "ai/deploy/.env is a symlink to a missing prescription store" — rather than the assertion, so the next person reads it as an environment fact in one line instead of a suite failure in a full run.

Test Evidence

deploymentPrescriptionEnvironment.spec.mjs — 8 passed, 1 skipped on the affected machine (was 8 passed, 1 failed).

Non-vacuity across all three states, because a skip that fires too widely hides real regressions and would be strictly worse than the false red it replaces:

state predicate behaviour
dangling symlink true skip — the machine cannot host the write
real .env file false runs, preserved and restored
absent path false runs — this is CI, and it must never be skipped

The third row is the load-bearing one: throwIfNoEntry: false returning undefined for an absent path is what keeps a clean checkout on the running side.

Full unit suite at dev HEAD before this change: 12856 passed / 1 failed (this test). The remaining 12856 are the evidence that dev itself was green — the merges were safe.

Post-Merge Validation

  • On a machine whose prescription store was removed, the suite reports one skip with a named reason instead of a failure on a repo path.
  • On CI, where .env does not exist, the test still executes and still convicts a prescription that fails to reach the container command.

PR Review Summary

Status: Comment

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Comment
  • Rationale: The exact test delta is semantically approve-ready. Formal approval is withheld only because GitHub still projects the exact-head CodeQL extraction guard as in progress, despite its workflow and every recorded step already showing success.

Peer-Review Opening: This is the right narrow repair. The three filesystem states are distinguished without weakening the real-file or absent-path controls; there is no code change requested.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Issue #16988, exact changed-file list, current dev, the existing prescription environment spec, exact-head checks, and the three filesystem object states.
  • Expected Solution Shape: Skip only when ai/deploy/.env is a dangling symlink, while keeping both an absent path and a real file runnable through the existing write/restore assertions.
  • Patch Verdict: Matches. Exact head 6dd8014082 uses lstat plus target resolution only in test setup and preserves the existing runnable path for absent and real-file states.
  • Premise Coherence: Coheres with verify-before-assert: the test now distinguishes an unavailable external carrier from a clean checkout instead of turning both into the same skip.

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #16988
  • Related Graph Nodes: deployment prescriptions, dangling symlink, unit-test precondition
  • Origin Session ID: 019fe5e5-a4aa-7c41-b1fc-4f8f06c73d59

🔬 Depth Floor

Documented search: I actively checked the dangling-symlink-only predicate, absent-path non-vacuity, real-file preservation, and hardcoded deployment-store coupling and found no semantic concern.

Rhetorical-Drift Audit (per guide §7.4):

  • PR description: matches the test-only delta
  • Anchor & Echo summaries: N/A
  • [RETROSPECTIVE] tag: N/A
  • Linked anchors: #16988 matches the exact false-red

Findings: Pass.


🧠 Graph Ingestion Notes

  • [KB_GAP]: None.
  • [TOOLING_GAP]: GitHub currently leaves the CodeQL extraction job projected in progress after all steps and the workflow concluded success.
  • [RETROSPECTIVE]: Test preconditions should distinguish path-object existence from target resolvability.

🎯 Close-Target Audit

  • Close-target identified: #16988
  • #16988 confirmed not epic-labeled

Findings: Pass.


N/A Audits — 📑 🪜 📡 🔗

N/A across listed dimensions: this is a test-only precondition repair with no public contract, external evidence requirement, OpenAPI description, or cross-skill convention.


🧪 Test-Evidence & Location Audit

  • Execution evidence: behavior/unit checks are green at 6dd8014082; CodeQL extraction guard remains projected in progress
  • Reviewer falsifier: absent=false, real-file=false, dangling-symlink=true
  • Test location: existing canonical deployment prescription environment spec

Findings: Semantic evidence passes; exact-head CI has one unresolved projection gate.


📋 Required Actions

To proceed with merging, please address the following:

  • GitHub must reconcile the exact-head CodeQL extraction guard to completed success. No author code or prose mutation is requested.

📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 100 - Correct test-local placement and no production coupling.
  • [CONTENT_COMPLETENESS]: 98 - All three filesystem states are distinguished.
  • [EXECUTION_QUALITY]: 98 - Small, direct, and cleanup-safe.
  • [PRODUCTIVITY]: 96 - Removes a false red without masking clean-checkout coverage.
  • [IMPACT]: 88 - Restores trustworthy unit-suite signaling.
  • [COMPLEXITY]: 100 - Minimal one-spec repair.
  • [EFFORT_PROFILE]: Quick Win - Test-only path-state correction.

Semantically ready; approval follows when the exact-head check projection itself reaches a terminal success.

PR Review Follow-Up Summary

Status: Approved

Cycle: Cycle 2 follow-up

Opening: The prior semantic review was clean and held only for an exact-head CodeQL check that remained non-terminal after its workflow completed; this follow-up re-checks the unchanged head after GitHub reconciled that projection.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Prior review https://github.com/neomjs/neo/pull/16989#pullrequestreview-4908336412, issue #16988, unchanged exact head, current check rollup, and the absent / regular-file / dangling-symlink predicate.
  • Expected Solution Shape: Skip only the dangling-symlink Compose precondition while leaving absent and regular-file states runnable. The exact-head merge gate must itself be terminal green; a completed parent workflow is not a substitute for the projected job/check state.
  • Patch Verdict: Matches. The three filesystem states remain correctly separated, and the previously wedged exact-head CodeQL extraction check now reports terminal success without a head change.
  • Premise Coherence: coheres: verify-before-assert — the approval follows the exact projected check state rather than inferring success from its completed parent workflow.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: The test-only delta remains exactly scoped to #16988, the sole evidence hold has cleared at the same head, and no behavior, architecture, safety, or close-target action remains.
