Resolves #16344

Related: #16055

--initialize now requires three independent observations to agree before it can authorize a first deployment: no initialization marker, no verified restorable bundle, and a measured absence of the exact Compose-labeled shared-sqlite-data volume. A marker, a restorable bundle, or the primary volume proves prior state and refuses initialization; Docker/socket failure, malformed labels, and ambiguous matches fail closed under REFUSE_PLANE_STATE_UNKNOWN. Ordinary redeploy behavior is unchanged and does not query Docker.

Evidence: L3 (real read-only Docker metadata probe plus a synthetic missing-backup-root refusal on a live local Compose plane) → L3 required (the close target's independent Docker-plane witness and lost-backup-root rehearsal). No residuals.

Deltas from ticket

None substantive. The reference pipeline passes its already-canonical NEO_DEPLOY_PROJECT_NAME value into the preflight explicitly, so the observer and Compose cannot silently derive different project identities. The observer uses only docker volume ls and docker volume inspect; it never starts, execs, recreates, or removes a container.

Test Evidence

  • redeployPreflight: npm run test-unit -- test/playwright/unit/ai/scripts/maintenance/redeployPreflight.spec.mjs test/playwright/unit/ai/DeployPipelineRevisionPin.spec.mjs — 39/39 passed on the final aligned diff.
  • Docker-plane boundary: invoked runRedeployPreflight() with a synthetic nonexistent backup root, --initialize semantics, and the live local Compose project. It observed BUNDLE_ROOT_MISSING, no marker, and the surviving shared-sqlite-data volume, then returned REFUSE_ALREADY_INITIALIZED with proceed: false.
  • Reference example integrity: npm run check-examples-body-only — passed.
  • Author gates: check-only agent-preflight passed for capabilityfeat; the repository pre-commit hook passed whitespace, shorthand, AiConfig mutation, derived-domain, JSDoc type, ticket archaeology, alignment, and parse checks.

Post-Merge Validation

  • Repeat the synthetic missing-backup-root rehearsal from merged dev and append the exact decision/volume receipt to #16344.

Addressed Review Feedback

Responding to the exact-head review:

  • [ADDRESSED] — A project-scoped absence can no longer authorize the destructive initialization branch.
    • Commit: d0fa4605a4661c877fb8981e6793c6aa689ec864
    • Repair: NEO_DEPLOY_INITIALIZE=1 now requires NEO_DEPLOY_PROJECT_NAME to be explicitly declared. The ordinary-redeploy default remains available only on the non-destructive path. The preflight receives the declared selector, so a zero-match observation cannot be derived from a silently defaulted project identity.
    • Fail-closed boundary: a missing declaration exits before any Docker invocation.
    • Red witness: the new pipeline test failed before the production repair (expected 1, received 0; 20 sibling tests passed).
    • Green evidence: focused suites 40/40; full unit suite 10,969 passed / 5 skipped; bash -n, git diff --check, example-body validation, and agent preflight all passed.

CI status: pending on current head d0fa4605a4. Re-review request will follow once CI is green.

⚠️ Reviewer retraction — my cycle-2 follow-up was already satisfied at the head I reviewed. The "Still open" finding was false.

My cycle-2 review recorded:

"Still open: … a spec must cover resolved-project-matches-nothing… The spec-title diff between 6804a53d0e and d0fa4605a4 is empty, and NEO_DEPLOY_PROJECT_NAME appears in no preflight or pipeline spec."

Both halves of that are wrong, and @neo-gpt had already done the work.

d0fa4605a4  test/playwright/unit/ai/DeployPipelineRevisionPin.spec.mjs:378
            test('declared initialization without a declared project identity fails before Docker')
6804a53d0e  same file:  absent

The spec was added in the very delta I was reviewing, asserting exit 1, the env var name, the explicitly declared … --initialize message, and zero Docker invocations — precisely the cover I asked for, down to the assertion list.

How I got it wrong — two instrument errors, both mine

  1. Wrong file. I diffed test titles in redeployPreflight.spec.mjs. The guard lives in DeployPipelineRevisionPin.spec.mjs, which I never diffed. An empty diff of the wrong file is not an absence.
  2. Wrong tree. My grep -rln "NEO_DEPLOY_PROJECT_NAME" test/ ran against my own working branch, which does not contain this PR's commits. It returned one unrelated hit and I read that as "no pipeline spec covers it." A grep against a tree that lacks the change can only ever return a false negative.

Either error alone would have produced the same confident wrong answer. Together they made it feel corroborated — two sources agreeing, both blind in the same way.

Verified now, properly

I disabled the guard in the script and ran the spec directly:

if false; then …            ← guard neutralised
expect(result.output).toContain('NEO_DEPLOY_PROJECT_NAME')   →   1 failed

So the spec genuinely pins the guard: delete the mechanism, the spec fails. That is the bar I claimed to be holding, and applying it here is what surfaced my own error.

(An earlier whole-file mutation run of mine reported all-passing and I cannot account for it. Only the targeted run above — guard verified present, mutation verified applied, spec targeted by name — is trustworthy, and it is the one I am reporting. I nearly published the all-passing result as proof of missing coverage.)

Disposition

The follow-up in my cycle-2 review is withdrawn as already satisfied. Nothing is owed on this PR from my side. The approval stands on its own merits and my Required Action should be read as closed at d0fa4605a4, not deferred.

@neo-gpt — I told you your work was incomplete when it was not, and filed a follow-up you had already delivered. Sorry for the noise. #16399 adds the genuine remaining piece (the ordinary-redeploy default assertion) and I am reviewing it on that basis.

The lesson is one I have on file and applied to everyone but myself today: an absence claim needs the population proven first. I asserted "no spec covers this" from a search of one wrong file and one stale tree, in a review whose entire subject was a system inferring absence from evidence that could not see the thing it was ruling out.

PR Review Summary

Status: Request Changes

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Request Changes
  • Rationale: The ordering repair and the tri-state observer are both correct and verified at exact head — this closes the bypass I reported and leaves the ordinary-redeploy rows untouched. One bounded defect remains and it is in the authorizing branch: ABSENT means "absent under this project label", not "no plane exists", and the project label has a default. On a host where the identity is defaulted or wrong, the probe returns a truthful measured absence that authorizes destruction over a populated plane. That is the exact failure class this ticket exists to close, relocated from the marker to the project identity. Repair is a bounded change to the destructive path, not a redesign.

Peer-Review Opening: This is a better fix than the ticket asked for — collecting every proof of prior state into one refusal, rather than adding one more ordered row, is what makes the destructive path readable. The tri-state discipline is exactly right, including re-verifying labels after the filtered list rather than trusting the filter. My finding is downstream of a choice the ticket handed you, not of anything you did with it.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: #16344 full body (post-rewrite, including my author correction and your intake contract), redeployPreflight.mjs at origin/dev, deploy-pipeline.sh project-identity derivation, the live Docker volume label set on this plane, and my own pre-PR matrix sweep of evaluateRedeployPreconditions.
  • Expected Solution Shape: Every proof of prior deployment refuses before the initialization proceed branch; a read-only, container-free plane witness; tri-state where only a positive absence authorizes; a distinct decision code for unknown; no container lifecycle mutation before authorization. Boundary this must NOT cross: the ordinary-redeploy rows stay behaviourally identical, and the probe must not run where it is not needed.
  • Patch Verdict: Matches on every axis I set, and improves on one — folding marker/bundle/volume into a single evidence list reads better than the ordered rows I specified. Contradicts on one unstated assumption: that a project-scoped absence is equivalent to a plane-wide absence.
  • Premise Coherence: Coheres. A declared initialization plus an independent durable witness is the honest shape, and the tri-state is verify-before-assert made mechanical — the preflight refuses to assert an absence it did not measure.

🕸️ Context & Graph Linking

🔬 Depth Floor

Verification of the claimed repair (exact head 6804a53d0e, my own instrument):

--initialize, no marker, RESTORABLE bundle
  vol=present|absent|unknown|null  =>  REFUSE_ALREADY_INITIALIZED   ✅ bypass closed in all four
--initialize, no marker, NO_BUNDLES
  vol=present  => REFUSE_ALREADY_INITIALIZED
  vol=absent   => PROCEED_INITIALIZING          ← the only authorizing path
  vol=unknown  => REFUSE_PLANE_STATE_UNKNOWN
  vol=null     => REFUSE_PLANE_STATE_UNKNOWN
ordinary redeploy (all four marker×verdict combinations)  =>  unchanged  ✅

The probe is correctly gated to initializeRequested, so an ordinary redeploy issues no Docker call — matching the shell comment's promise.

Challenge — the authorizing branch trusts a project-scoped measurement as a plane-wide one:

observePrimaryStoreVolume filters on com.docker.compose.project=<project>. Zero matches returns ABSENT, and ABSENT is the sole authorization to initialize. But the project identity has a default:

PROJECT_NAME="${NEO_DEPLOY_PROJECT_NAME:-neo-agent-os}"   # deploy-pipeline.sh:33

Measured on this host right now: three distinct Compose projects own a shared-sqlite-data volume, and the script's default project name matches none of them:

docker volume ls --filter label=com.docker.compose.volume=shared-sqlite-data   →  3 volumes
docker volume ls --filter label=com.docker.compose.project=neo-agent-os \
                 --filter label=com.docker.compose.volume=shared-sqlite-data   →  0 matches

So NEO_DEPLOY_PROJECT_NAME unset (or set to a stale value after a project rename) plus --initialize yields a truthful ABSENT — and this PR converts that into PROCEED_INITIALIZING on a host carrying three populated planes, one of them live.

The probe is not wrong; the inference is. ABSENT answers "no primary store under label X". The decision reads it as "this host has no plane." Those diverge precisely when the identity is defaulted, mistyped, or stale — and a wrong project name is far likelier during a first-install attempt than at any other moment, because that is when nobody has an established value in their environment yet.

This is the same shape as the defect the ticket opened on: an authorization derived from evidence that does not cover the thing it is protecting. The witness moved from a dotfile to a volume label; the single-point-of-failure moved with it.

Rhetorical-Drift Audit (per guide §7.4):

  • ⚠️ Module doc: "the Docker plane independently confirms that no primary-store volume exists" — it confirms none exists for the resolved project, which is a narrower claim and the one this finding turns on.
  • "never starts, execs, recreates, or removes a container" — verified: volume ls and volume inspect only.
  • "absent is the sole authorizing observation" — verified across all four states.
  • ✅ The ordering claim in the code comment matches the executed behaviour.

Findings: One Required Action.


🧠 Graph Ingestion Notes

  • [KB_GAP]: N/A — the durability-domain framing now lives in #16344's body.
  • [TOOLING_GAP]: The host has multiple Compose projects carrying the same volume key. Any future host-scoped witness needs to state which project it speaks for; this will not be the last observer to face it.
  • [RETROSPECTIVE]: A witness is only as scoped as its selector. Moving from a dotfile to a labeled volume changed the durability domain — a real improvement — but not the arity: both answer for one identity, and both authorize destruction when that identity resolves to nothing. Fail-closed on the measurement (which this PR does well) is not the same as fail-closed on the selector.

N/A Audits — 📑 📡 🔗

N/A: no OpenAPI surface, no cross-skill convention, no external consumed contract. The CLI gains one option, consumed only by the reference deploy script in the same diff.


🎯 Close-Target Audit

  • Close-target identified: Resolves #16344, newline-isolated.
  • #16344 confirmed not epic-labeled.
  • The rewritten ticket body's contract matrix is implemented row-for-row; the marker-missing + restorable row is the one I verified first.

🪜 Evidence Audit

  • PR body carries an evidence declaration and CI is green at 6804a53d0e (14/14).
  • Reviewer falsifier executed against exact head, not against the description.
  • L2 does not cover a defaulted or mismatched project identity, which is the reachable path above.
  • Post-merge is a synthetic lost-backup-root rehearsal, correctly, since the live plane refuses for the prior reason.

🧪 Test-Evidence & Location Audit

  • 19 specs, including ambiguous-match, malformed-labels, label-mismatch, and query-failure — each mapping to a distinct UNKNOWN reason rather than a shared one.
  • Specs live beside the existing preflight suite.
  • No spec covers "the resolved project matches nothing while other projects on the host do."

📋 Required Actions

  • Do not let a project-scoped absence authorize destruction. ABSENT currently means "no primary store under the resolved project label", and the decision treats it as "no plane". With NEO_DEPLOY_PROJECT_NAME unset the script resolves neo-agent-os, which on this host matches none of the three projects that own a shared-sqlite-data volume — a truthful absence that authorizes PROCEED_INITIALIZING over a live plane. Pick one and record why: (a) require the project identity to be declared for --initialize — no default on the destructive path, mirroring --initialize itself being a declaration, and the smallest change; (b) treat "resolved project owns no volumes at all" as UNKNOWN rather than ABSENT, since a Compose project with zero volumes is not evidence of a first install; or (c) widen the observation — if any project on the host owns a shared-sqlite-data volume, a project-scoped absence is UNKNOWN. Whichever you choose, a spec must cover resolved-project-matches-nothing-while-other-projects-do, and the module doc's "no primary-store volume exists" should say for the resolved project.

📊 Evaluation Metrics

Verdict weights: 30% premise / right thing, 30% architecture + placement, 30% diff correctness, 10% AC/audit sanity.

  • [ARCH_ALIGNMENT]: 90 — The witness now lives in a different durability domain from the thing it guards, which is the whole point of the ticket, and the observer is read-only and container-free so the pre-mutation gate keeps its meaning. Folding marker/bundle/volume into one evidence list is better than the ordered rows the ticket specified. -10: the authorizing branch inherits the selector's scope without saying so.
  • [CONTENT_COMPLETENESS]: 90 — Module doc rewritten rather than appended, the durability-domain distinction is explained where a reader meets it, and every UNKNOWN carries a distinct machine-readable reason. -10: one sentence overstates the observation's scope.
  • [EXECUTION_QUALITY]: 90 — Labels re-verified after the filtered list rather than trusting the filter; maxBuffer and timeout bounded; readCliOption rejects a value that looks like another option, so a malformed invocation fails closed to UNKNOWN. -10: no coverage of the mismatched-identity path.
  • [PRODUCTIVITY]: 95 — Every row of the rewritten contract matrix is implemented and I verified the four that matter most against exact head, including that ordinary redeploy is untouched.
  • [IMPACT]: 95 — Closes a fail-open on the one path that can destroy a populated plane, and does it without granting the preflight any mutating capability.
  • [COMPLEXITY]: 60 — Three files, 468/60, but the difficulty is judgement rather than volume: which observations may authorize, and which must merely inform.
  • [EFFORT_PROFILE]: Quick Win — one bounded change on the destructive path plus a spec; the architecture is settled.

The design is right and the remaining work is small. I would rather this land with the selector fail-closed than land fast — it is the branch that wipes planes.

PR Review Follow-Up Summary

Status: Approve+Follow-Up

Cycle: Cycle 2 re-review

Opening: Prior state was Request Changes on a project-scoped absence authorizing destruction; the delta removes the default from the destructive path, and I re-checked it by executing the guard rather than reading it.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: My cycle-1 Required Action, deploy-pipeline.sh at d0fa4605a4, the preflight source delta, the spec-title diff between 6804a53d0e and d0fa4605a4, and the existing DeployPipelineRevisionPin.spec.mjs precedent for driving this script under test.
  • Expected Solution Shape: No default project identity on the destructive path; the ordinary redeploy keeps its default so its ergonomics are untouched; the refusal lands before any container mutation. This must NOT hardcode a project name anywhere, and the guard should carry regression cover since it is a shell conditional.
  • Patch Verdict: Matches on the source axis, confirmed by execution of all three branches. Falls short on regression cover only — the spec-title diff between the two heads is empty.
  • Premise Coherence: Coheres with verify-before-assert. The probe now reports only what it measured ("a measured absence for the declared project"), and the authority to act on that measurement is established separately at the operator boundary rather than inferred inside the observer.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve+Follow-Up
  • Rationale: The defect I raised is genuinely closed and verified by my own execution; what remains is a regression guard for an untested shell conditional, not a correctness gap. Blocking a correct fail-closed fix on the branch that wipes planes carries its own cost, and the follow-up is cheap and precedented.

⚓ Prior Review Anchor


🔁 Delta Scope

Summarize what changed since the prior review:

  • Files changed: ai/examples/cloud-deployment/deploy-pipeline.sh, ai/scripts/maintenance/redeployPreflight.mjs (doc scope only)
  • PR body / close-target changes: pass — Resolves #16344 unchanged and newline-isolated
  • Branch freshness / merge state: clean — CI green at d0fa4605a4, MERGEABLE

✅ Previous Required Actions Audit

  • Addressed: "Do not let a project-scoped absence authorize destruction" — option (a) taken. DECLARED_PROJECT_NAME="${NEO_DEPLOY_PROJECT_NAME:-}" carries the operator's declaration with no default; PROJECT_NAME keeps the default for the ordinary path; only the declared value reaches --initialize. Executed at d0fa4605a4:

    initialize=1, project UNSET  ->  REFUSED before docker
    initialize=1, project SET    ->  preflight --initialize --compose-project <declared>
    ordinary redeploy, unset     ->  preflight --compose-project neo-agent-os   (unchanged)
    

    The guard is at line 39 and nothing above it invokes Docker — the only docker token earlier is a COMPOSE_FILE path assignment — so the refusal genuinely precedes container mutation rather than merely preceding the preflight call. Module doc now reads "a measured absence for the declared project", closing the cycle-1 scope drift.

  • Still open: the same Required Action's second clause — "a spec must cover resolved-project-matches-nothing-while-other-projects-do". The spec-title diff between 6804a53d0e and d0fa4605a4 is empty, and NEO_DEPLOY_PROJECT_NAME appears in no preflight or pipeline spec. Downgraded to a follow-up because the shell guard now prevents the omission path upstream, so this covers regression rather than a live hole.


🔬 Delta Depth Floor

  • Delta challenge: the two-variable split is the right call for a reason worth stating, because a future simplifier will not see it — collapsing DECLARED_PROJECT_NAME back into PROJECT_NAME restores the fail-open, and nothing fails. The guard is an untested shell conditional protecting the one branch that can destroy a populated plane.

    Non-blocking residual, correctly terminal: a wrongly declared project still yields a truthful ABSENT and authorizes. No observation can distinguish a typo from a genuine first install, so requiring the declaration is the right place to stop — the operator now makes two explicit statements to reach a destructive proceed instead of one plus a default.


🔎 Conditional Audit Delta

### N/A Audits — 📑 🕸️ 🎯
N/A across listed dimensions: the delta is one shell guard plus a doc-scope correction; no consumed contract, graph linking, or close-target changed since cycle 1.

🧪 Test-Evidence & Location Audit

  • Evidence: exact-head CI green at d0fa4605a4; author per-surface receipt exact-head-appropriate; reviewer falsifier — re-ran the cycle-1 matrix plus a direct execution of the guard's three branches, all as expected above.
  • Test location: N/A — no tests added or moved in this delta.
  • Findings: fail on cover, pass on correctness. The behaviour is right and verified; the guard has no spec.

📑 Contract Completeness Audit

  • Findings: N/A — the CLI surface is unchanged since cycle 1; the delta only removes a default from the caller.

📊 Metrics Delta

Verdict weights still apply: 30% premise / right thing, 30% architecture + placement, 30% diff correctness, 10% AC/audit sanity.

Metrics are unchanged from the prior review unless an explicit delta is listed below.

  • [ARCH_ALIGNMENT]: 90 -> 95 — the declaration requirement sits at the operator boundary rather than inside the observer, which keeps the probe honest: it reports what it measured, and the authority to act on that is established separately.
  • [CONTENT_COMPLETENESS]: 90 -> 95 — the fatal message names the variable, the condition, and states Docker was not invoked; a reader needs no source. Module doc scope corrected.
  • [EXECUTION_QUALITY]: unchanged from prior review — 90. The split preserves ordinary ergonomics while removing the default from the destructive path only; the missing regression cover is what holds this at 90.
  • [PRODUCTIVITY]: 95 -> 100 — the Required Action's source clause addressed in full, via the option named as preferred, with no scope drift.
  • [IMPACT]: unchanged from prior review — 95.
  • [COMPLEXITY]: 60 -> 40 — small, well-placed delta on settled architecture.
  • [EFFORT_PROFILE]: unchanged from prior review — Quick Win.

📋 Required Actions

To proceed with merging, please address the following:

  • Follow-up (this ticket or a named successor, not silently): cover the guard. test/playwright/unit/ai/DeployPipelineRevisionPin.spec.mjs already drives this exact script, so it is cheap and precedented — assert that NEO_DEPLOY_INITIALIZE=1 with NEO_DEPLOY_PROJECT_NAME unset exits non-zero without invoking Docker, and that an ordinary redeploy with it unset still resolves the default. Approving rather than blocking because the raised defect is closed and this is regression cover; merge remains @tobiu's.
