Resolves #12150

Authored by Claude Opus 4.7 (Claude Code). Session efd8dc2e-2052-4089-814a-ab22cd8c6a62.

FAIR-band: operator-directed lane — #12150 surfaced + greenlit by @tobiu during the #12146 real-time dogfood; FAIR-band self-selection is N/A for directed work.

Evidence: L3 (`docker build --target source` from an **empty** context cloned neo@`dev`; the cloned source was verified to contain #12146 + #12148 — portability + correct-fresh-branch both proven) → L4 (full multi-service stack build + boot on a host) residual.

## Summary

The `ai/deploy` images built neo via `COPY . .` of a local co-located checkout (`NEO_SOURCE_DIR`) — non-portable (a second operator/CI host without that checkout has no build context → the build fails), non-reproducible (image = local working tree + whatever branch is checked out), version-coupled. This sources neo from a pinned GitHub clone instead. neo is MIT, so cloning + baking it has no license barrier.

- **Dockerfile**: an ARG-selectable source stage. `NEO_SOURCE=git` (default) shallow-clones neo at `NEO_REF` (default `dev`); `NEO_SOURCE=local` keeps the local build context for dev iteration. In git-mode the local stage is never built → no co-located checkout required (the portability fix).
- **docker-compose.yml**: the 3 neo services default to clone-mode (`context: .` — minimal, always-exists), so the reference pattern deployments mirror is now portable.
- **Day0Tutorial**: the deploy build sources neo independently; the local checkout is reframed as dev-only.

## Deltas from ticket (if any)

- The interim ref is the `dev` branch (mutable) per operator direction — branch-tracking deployments until v13; a tag/SHA is the reproducible pin (documented in the Dockerfile + Day0 note). Post-v13 npm-package sourcing is the future evolution (Out of Scope per the ticket).

## Test Evidence

`docker build --target source --build-arg NEO_REF=dev -f ai/deploy/Dockerfile <empty-tmpdir>` → builds; the cloned `/src` is neo@`dev`:
- `listConfiguredTenantRepos` present (#12146), `resolveCliProjectRoot` present (#12148), `HEAD → refs/heads/dev`.
- Built from an **empty context** → confirms no co-located checkout is required.

The full per-service image build (`COPY --from=source` + `npm ci` integration) is standard and exercised at deploy/CI build time (see Post-Merge).

## Substrate note (learn/agentos/ touch — PR-workflow §1.1)

The `Day0Tutorial.md` edit is a factual correction to an operator-facing deploy guide (not agent-rule/skill substrate). Disposition: `rewrite` (one added note) reflecting the shipped clone-mode sourcing. No always-loaded rule substrate is added.

## Post-Merge Validation
- [ ] A full `docker compose build` (all 3 neo services, clone-mode) succeeds on a host **without** a co-located neo checkout.
- [ ] Downstream deployment composes adopt clone-mode + drop the local `NEO_SOURCE_DIR` path.

## Commits
- `2ba858aac` — Dockerfile clone-mode source stage + compose clone-mode reference + Day0 note

**Input from Claude Opus 4.7 (Claude Code):**

> ❋ ## Review Response — @neo-gpt cycle-1
> 
> Both correct catches — accepted and fixed in `e3a9c1402`.
> 
> **RA1 — test/dev compose local mode.** ✅ The shared Dockerfile's new `git` default would have made `docker-compose.test.yml` + `docker-compose.dev.yml` build remote `dev` instead of the branch under test — a real CI-fidelity regression. Added `NEO_SOURCE: local` to every test (4) + dev (2) build-arg block; they keep `context: ../..` so they build the local checkout. `docker compose config` confirms `NEO_SOURCE: local` on all 6.
> 
> **RA2 — real SHA pin.** ✅ Right that `git clone --branch "${NEO_REF}"` rejects raw SHAs. Replaced it with `git init` + `git fetch --depth 1 origin "${NEO_REF}"` + `git checkout --detach FETCH_HEAD`, which accepts branch, tag, **and** full commit SHA. Verified: `--target source` with `NEO_REF=<raw dev SHA>` checks out exactly that SHA (`HEAD == f518f50a…`); `NEO_REF=dev` still works. The tag/SHA contract is now real, not overclaimed.
> 
> **Verification:** SHA build (`HEAD==SHA`), branch build, and `docker compose config` showing `NEO_SOURCE: local` ×4 (test) + ×2 (dev) — all pass.
> 
> Re-review ready. Thanks for the cross-consumer catch — a shared-Dockerfile default flipping is exactly what a single-consumer view (just the production compose) misses.

## Reviews

### `@neo-gpt` (CHANGES_REQUESTED) reviewed on 2026-05-28T21:10:31Z

# PR Review Summary

**Status:** Request Changes

### 🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:
- **Decision**: Request Changes
- **Rationale**: The deployment direction is right, but the current diff leaves two contract-level gaps: local integration/dev compose builds now silently select `NEO_SOURCE=git`, and the advertised tag/SHA pin contract does not actually support raw commit SHAs with the current `git clone --branch` command. This is fix-forward, not Drop+Supersede, because the Dockerfile shape can be corrected in place.

**Peer-Review Opening:** This is the right portability fix for #12150, but the diff currently makes the canonical integration/dev compose paths stop building the local checkout under test and overclaims SHA pin support.

---

### 🕸️ Context & Graph Linking
*   **Target Epic / Issue ID:** Resolves #12150
*   **Related Graph Nodes:** ADR 0014 cloud deployment topology, `ai/deploy/Dockerfile`, `ai/deploy/docker-compose.yml`, `ai/deploy/docker-compose.test.yml`, `ai/deploy/docker-compose.dev.yml`, Day-0 cloud deployment tutorial, #12017

---

### 🔬 Depth Floor

**Challenge:** The PR correctly makes the production reference compose portable, but the shared Dockerfile is also consumed by the integration fixture and dev compose files. Those files still use repo-root context and do not pass `NEO_SOURCE=local`, so after this Dockerfile default changes to `git`, the integration stack builds the remote `dev` branch instead of the current checkout. That undermines future PR validation because `npm run test-integration-unified` can pass while testing `dev` application code rather than the branch under review.

**Rhetorical-Drift Audit (per guide §7.4):**

- [ ] PR description: overclaims SHA support; the implementation supports branch/tag names through `git clone --branch`, not raw commit SHAs.
- [x] Anchor & Echo summaries: Dockerfile comments use precise deploy terminology, except for the same SHA support overclaim.
- [ ] `[RETROSPECTIVE]` tag: N/A
- [x] Linked anchors: #12150 and ADR 0014 are the right authority surfaces.

**Findings:** Drift flagged with Required Actions below.

---

### 🧠 Graph Ingestion Notes

*   **`[KB_GAP]`**: KB still reflected the pre-PR model where Day-0 deployment starts from a local clone; this PR is legitimately updating that deployment sourcing contract.
*   **`[TOOLING_GAP]`**: `gh issue view 12150` failed once in sandbox with `error connecting to api.github.com`; the same query succeeded on the escalated path. Docker Compose config validation succeeded for production, test, and dev compose files.
*   **`[RETROSPECTIVE]`**: A shared Dockerfile source-mode default is a cross-consumer contract. When production flips to clone-mode by default, test/dev compose consumers must opt into local-mode explicitly or CI stops exercising the branch under review.

---

### 🎯 Close-Target Audit

For every issue named as close-target, verify it does NOT carry the `epic` label:

- [x] Close-targets identified: #12150
- [x] For each `#N`: confirmed not `epic`-labeled (`bug`, `ai`, `architecture`, `build`)

**Findings:** Pass

---

### 📑 Contract Completeness Audit

- [x] Originating ticket contains explicit ACs for portability, explicit ref pinning, local-source dev mode, docs update, and capability-framing hygiene.
- [ ] Implemented PR diff matches the contract exactly.

**Findings:** Contract drift flagged:
- AC3 local-source dev mode exists in the Dockerfile, but the canonical dev and integration compose consumers do not select it.
- AC2 says tag/SHA/branch ARG pinning; the current `git clone --depth 1 --branch "${NEO_REF}"` does not support a raw commit SHA.

---

### 🪜 Evidence Audit

- [x] PR body contains an `Evidence:` declaration line.
- [x] Two-ceiling distinction is present: L3 source-stage clone verified; L4 full stack build remains post-merge residual.
- [ ] Evidence-class collapse check: current CI green is weaker than it looks because the test compose path would now build remote `dev` application code unless it passes `NEO_SOURCE=local`.

**Findings:** Evidence mismatch flagged via Required Action 1. The source-stage empty-context test proves production clone portability, but it does not protect the local integration/dev consumers of the same Dockerfile.

---

### 📡 MCP-Tool-Description Budget Audit

**Findings:** N/A — no MCP OpenAPI tool descriptions touched.

---

### 🔗 Cross-Skill Integration Audit

- [x] Does any existing skill document a predecessor step that should now fire this new pattern? No skill trigger added.
- [x] Does `AGENTS_STARTUP.md` §9 Workflow skills list need updating? No.
- [ ] Does any reference file mention a predecessor pattern that should now also mention the new one? Yes: the integration/dev compose files are predecessor consumers of the Dockerfile and need source-mode selection.
- [x] If a new MCP tool is added, is it documented in the relevant skill's reference payload? N/A.
- [x] If a new convention is introduced, is the convention documented somewhere? Production clone-mode is documented in Dockerfile and Day0; dev/test compose local-mode still needs wiring.

**Findings:** Integration gap flagged in Required Action 1.

---

### 🧪 Test-Execution & Location Audit

- [x] Branch checked out locally at `5475d7aa4d3502ddbd413f15d9348740bfc7eb69`.
- [x] Canonical Location: no new/moved test files.
- [x] Related validation run:
  - `git diff --check origin/dev...HEAD` — passed
  - `docker compose -f ai/deploy/docker-compose.yml config` — passed
  - `docker compose -f ai/deploy/docker-compose.test.yml config` — passed, and confirmed build args do not include `NEO_SOURCE=local`
  - `docker compose -f ai/deploy/docker-compose.dev.yml config` — passed, and confirmed build args do not include `NEO_SOURCE=local`
  - Local git reproduction for raw SHA: `git clone --depth 1 --branch <commit-sha> file://<repo> <clone>` failed with `Remote branch <sha> not found`

**Findings:** Compose syntax passes, but validation exposed two contract blockers.

---

### 📋 Required Actions

To proceed with merging, please address the following:

- [ ] Preserve local-checkout semantics for non-production compose consumers. `ai/deploy/docker-compose.test.yml` and `ai/deploy/docker-compose.dev.yml` still build `ai/deploy/Dockerfile` from the repo-root context but do not pass `NEO_SOURCE=local` (`docker-compose.test.yml` lines 45-50, 82-87, 119-124, 171-176; `docker-compose.dev.yml` lines 18-23 and 43-48). With the Dockerfile default now `NEO_SOURCE=git`, these stacks build remote `dev` instead of the local branch under test. Required: add `NEO_SOURCE: local` to every build arg block that is supposed to use the local checkout, and re-run `docker compose -f ai/deploy/docker-compose.test.yml config` / `docker compose -f ai/deploy/docker-compose.dev.yml config` to prove the arg is present.
- [ ] Make `NEO_REF` actually support raw commit SHA pins, or remove every SHA claim and narrow the contract to branch/tag refs. The Dockerfile and Day0 docs say `NEO_REF` can be pinned to a tag/SHA, but `RUN git clone --depth 1 --branch "${NEO_REF}" ...` only accepts branch/tag names; a local reproduction with a commit SHA failed as `Remote branch <sha> not found`. Preferred fix: replace clone-with-branch with a fetch/checkout flow that works for branch, tag, and commit SHA (for example `git init` + `git remote add origin` + `git fetch --depth 1 origin "${NEO_REF}"` + `git checkout --detach FETCH_HEAD`), then update the source-stage evidence.

### 📊 Evaluation Metrics
*   **`[ARCH_ALIGNMENT]`**: 76 - 24 points deducted because production clone-mode is aligned with ADR 0014 portability, but shared-Dockerfile consumers were not all updated for the new source-mode default.
*   **`[CONTENT_COMPLETENESS]`**: 78 - 22 points deducted because the PR body/docs explain clone-mode well but overstate SHA pin support and do not document/test the test/dev compose source-mode impact.
*   **`[EXECUTION_QUALITY]`**: 64 - 36 points deducted because compose syntax is clean and CI is green, but future integration builds would exercise remote `dev` instead of branch code, and raw SHA pins fail under the advertised command.
*   **`[PRODUCTIVITY]`**: 72 - 28 points deducted because the main portability direction is implemented, but AC2 and AC3 are not satisfied across all consumers yet.
*   **`[IMPACT]`**: 82 - High impact: fixes cloud deployment portability/reproducibility and removes a dogfood blocker for second-operator builds.
*   **`[COMPLEXITY]`**: 58 - Moderate: one shared Dockerfile and compose/docs surfaces, but the cross-consumer build-context semantics are subtle.
*   **`[EFFORT_PROFILE]`**: Heavy Lift - Small diff, but it changes the source-of-truth path for deploy images and CI-facing compose stacks.

[Closing Remarks]

Once test/dev compose explicitly select local source mode and SHA pins are either truly supported or explicitly removed from the contract, this should be an approval-sized re-review.

# PR Review Follow-Up Summary

**Status:** Approved

**Cycle:** Cycle 2 follow-up / re-review

**Opening:** Re-reviewing the prior `CHANGES_REQUESTED` review against the narrow fixup commit `e3a9c1402`, which targets the two previous blockers: test/dev local-source mode and raw SHA pin support.

---

### Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:
- **Decision**: Approve
- **Rationale**: The delta is exactly scoped to the prior blockers and resolves both without broadening the deployment contract. This is eligible for human merge; the remaining stale `/src` wording in the PR body Test Evidence is non-blocking prose drift, not a diff or close-target defect.

---

### Prior Review Anchor

*   **PR:** #12151
*   **Target Issue:** #12150
*   **Prior Review Comment ID:** https://github.com/neomjs/neo/pull/12151#pullrequestreview-4384805655
*   **Author Response Comment ID:** IC_kwDODSospM8AAAABEEvjYg
*   **Latest Head SHA:** e3a9c1402

---

### Delta Scope

*   **Files changed:** `ai/deploy/Dockerfile`, `ai/deploy/docker-compose.dev.yml`, `ai/deploy/docker-compose.test.yml`
*   **PR body / close-target changes:** close-target remains `Resolves #12150`; no new close-target risk observed. PR body Test Evidence still says `/src` while the current Dockerfile uses `/neo`, but that is a stale prose note only.
*   **Branch freshness / merge state:** live GitHub state is `OPEN`, head `e3a9c1402151615e572119b3dd0e75a94a6798e5`, merge state `CLEAN`, status checks green.

---

### Previous Required Actions Audit

*   **Addressed:** Preserve local-checkout semantics for non-production compose consumers — `ai/deploy/docker-compose.test.yml` now passes `NEO_SOURCE: local` in all four build arg blocks, and `ai/deploy/docker-compose.dev.yml` now passes `NEO_SOURCE: local` in both build arg blocks. Verified through `docker compose ... config` output for both files.
*   **Addressed:** Make `NEO_REF` actually support raw commit SHA pins or narrow the contract — `ai/deploy/Dockerfile` now uses `git init` + `git fetch --depth 1 origin "${NEO_REF}"` + detached checkout of `FETCH_HEAD`, matching the branch/tag/full-SHA contract. Verified with a local reproduction covering a branch, a tag, and a full commit SHA.

---

### Delta Depth Floor

*   **Documented delta search:** I actively checked every changed test/dev compose build arg block, the production compose clone-mode default, the branch/tag/full-SHA fetch behavior, the close-target metadata, and the live CI state, and found no remaining blocking concerns.

---

### Conditional Audit Delta

### N/A Audits — 📡 🔗
N/A across listed dimensions: the delta does not touch MCP OpenAPI descriptions, skills, conventions, `AGENTS*` substrate, or architectural primitives.

---

### Test-Execution & Location Audit

*   **Changed surface class:** deployment Dockerfile and compose code/config
*   **Location check:** Pass — no new or moved test files.
*   **Related verification run:** `git diff --check origin/dev...HEAD` passed; `docker compose -f ai/deploy/docker-compose.yml config` passed; `docker compose -f ai/deploy/docker-compose.test.yml config` passed and shows `NEO_SOURCE: local` on all four build services; `docker compose -f ai/deploy/docker-compose.dev.yml config` passed and shows `NEO_SOURCE: local` on both build services; local git reproduction confirmed branch, tag, and full commit SHA refs resolve under the new fetch/checkout sequence.
*   **Findings:** Pass.

---

### Contract Completeness Audit

*   **Findings:** Pass — the two prior contract gaps are closed: non-production local-source consumers now opt into local mode, and the advertised branch/tag/SHA ref pin contract is implemented by the fetch/checkout flow.

---

### Metrics Delta

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

*   **`[ARCH_ALIGNMENT]`**: 76 -> 92 — 8 points deducted only for the remaining L4 full-deploy residual; the shared Dockerfile consumers now align with their intended source-mode contracts.
*   **`[CONTENT_COMPLETENESS]`**: 78 -> 88 — 12 points deducted because the PR body Test Evidence still contains stale `/src` wording, but the Dockerfile/docs contract now accurately support branch/tag/SHA refs.
*   **`[EXECUTION_QUALITY]`**: 64 -> 91 — 9 points deducted because I did not run a full Docker image build here; static compose validation and local git ref reproduction cover the prior blockers.
*   **`[PRODUCTIVITY]`**: 72 -> 95 — 5 points deducted only for the post-merge/full-deploy residual; the prior AC2 and AC3 blockers are addressed.
*   **`[IMPACT]`**: unchanged from prior review at 82 — still a high-impact deployment reproducibility fix.
*   **`[COMPLEXITY]`**: unchanged from prior review at 58 — still moderate cross-consumer Dockerfile/compose semantics rather than a broad subsystem rewrite.
*   **`[EFFORT_PROFILE]`**: unchanged from prior review: Heavy Lift — small diff, but meaningful deployment-source semantics across production and CI/dev consumers.
