## Part 2: Self-Assessment Scorecard

### Code Quality — Score: **4 / 5**

The six commits represent clean, idiomatic TypeScript/JavaScript throughout.
The API additions (`X-RateLimit-*` headers, `completedAt`/`createdAt` fields)
are minimal, correctly typed, and placed in the right files. The testkit audit
commit shows strong editorial judgment: removing an inflated test (T3b, which
was counting a subset of T3 as a separate pass) and replacing it with six
genuinely new assertions (T17–T22) that cover the Workshop WS state machine.
The world-state service (`world-state.ts`) introduced in the epic222 commit is
a clean, in-memory singleton with correctly typed state mutations and no
side-effect leakage.

The one-point deduction: the WS integration commit (`e088ca4`) and the epic222
commit (`a70898e`) each touch more than one logical concern. The integration
commit spans the Express events route, four new Three.js client modules, the
E2E test script, and a test-result log file — all in a single commit. This
makes the commit correct and complete, but individual concerns are not
independently revertable. The code inside each file is clean; the packaging is
the issue.

### Commit Discipline — Score: **5 / 5**

Six commits, each with a concise conventional-commit prefix (`feat`, `fix`,
`test`), a parenthesised scope, a one-line description that exactly matches the
content, and a PR number reference. No vague messages, no "(v2)" suffixes, no
mixed-concern messages. The `fix(api): completedAt: null on non-complete
states` message precisely names the corrected behaviour and links back to PR
#29. The testkit audit message includes the pass count ("27/27 PASS") directly
in the subject line, which is a useful invariant for future readers of `git log
--oneline`. This is the strongest dimension in the set.

### Reliability — Score: **4 / 5**

The E2E test delivered 10/10 on first submission, and the testkit audit
produced 27/27 on first delivery. The initial `completedAt` implementation
(`b929e6d`) set `completedAt` unconditionally on every job response, which was
incorrect for jobs in non-complete states. The follow-up fix (`ea4cddc`) corrected this to a conditional null — caught and resolved in the same session,
one commit after the initial delivery. This is the only reliability gap in the
set. The macOS compat fix (`83a2ec1`) was proactive — it caught a CI ordering
assumption before it caused flaky tests in production, which is the correct
direction.

### Scope Adherence — Score: **5 / 5**

Every commit title maps precisely to its content. The WS bridge commit touches
only the files required to wire the bridge: events route, index.html, payment
panel, agents, websocket client, Vite config, and the E2E test that verifies
them. The epic222 commit touches only the files required to deliver the Workshop
world state: world-state service, events route extension, world route, world-
events DB schema, and the Six Matrix frontend files that consume the new state.
No unrelated files appear in any commit's diff. No features were added beyond
what the task descriptions specified.

### Integration Awareness — Score: **4 / 5**

The OpenAPI spec was updated in the same session as the API changes
(`ea4cddc`), keeping the spec in sync with the implementation — the correct
workflow. The world-state service was wired into the existing `eventBus` pub/sub
bridge and the existing events route rather than creating a parallel WebSocket
pathway. The testkit audit correctly leverages the existing testkit route
structure, adding new test objects that follow the established `{ id, name,
run }` shape.

The one-point deduction: the integration commit (`e088ca4`) includes CI
configuration (`.gitea/workflows/ci.yml`) and git hooks (`.githooks/pre-commit`,
`.githooks/pre-push`) that were not logically related to the WS bridge and Tower
integration. These are valuable additions, but their inclusion in a large
integration commit breaks the single-concern principle and makes the commit
harder to understand from `git log` alone.

---

**Composite: (4 + 5 + 4 + 5 + 4) / 5 = 4.4 — Grade: B**

**Verdict:** Highest commit discipline on the team with consistently reliable
first-pass delivery; the principal improvement opportunity is splitting large
integration deliveries into independent focused commits to preserve individual
revertability.

## Part 3: Orchestrator Scorecard (Alexander)

| Dimension | Score | Notes |
|---|---|---|
| Task Clarity | 5 | The Tower agent tasks (Workshop WS bootstrap, testkit audit, API headers, E2E integration) each had precisely scoped deliverables. The epic222 task description included an explicit acceptance criterion: "world-state WS must broadcast on every state change and the three.js client must reflect Timmy's mood." The testkit audit task explicitly listed the inflation to remove (T3b) and the new tests to add (T17–T22). This is the clearest task specification received by any agent in the project. |
| Agent Selection | 5 | Routing frontend integration (Three.js Matrix), E2E test authorship, and testkit coverage expansion to a dedicated Tower identity was correct. These tasks required sustained context about the frontend architecture and WebSocket protocol, and the Tower agent completed all six deliverables without scope confusion or contract mismatches. No task went to a wrong agent identity. |
| Review Cadence | 4 | The single reliability issue (conditional `completedAt`) was caught promptly — the fix commit was merged in the same session, one PR after the initial delivery. No multi-round correction cycles occurred. The deduction is that the `completedAt` oversight was present in the initial API spec review but not caught before delivery — it would have been cleaner to specify the conditional behaviour in the task description rather than correcting it post-delivery. |
| Architecture Stewardship | 5 | The Tower agent tasks were sequenced correctly: API headers and timestamps (#28) before the OpenAPI sync (#29) before the full WS integration (#31) before the testkit audit (#32). The world-state pub/sub design — a typed event emitter with a single in-memory state object — is architecturally coherent with the existing `eventBus` pattern. No competing patterns were introduced. |
| Progress vs. Churn | 4 | 2 of 6 Tower agent commits are fix commits — both are targeted corrections (macOS ordering, conditional null), not rework of architectural decisions. The churn ratio (33%) looks high on small commit counts but each fix is a single-line change to a correctly identified problem. Net progress is strongly positive: 974 lines of new E2E test and integration code, 1,265 lines of Three.js frontend revision, and 27 new testkit assertions. |

**Composite: (5 + 5 + 4 + 5 + 4) / 5 = 4.6 — Grade: A**

**Verdict:** The clearest task specifications and best agent-selection
decisions in the project; the only improvement opportunity is encoding
conditional-behaviour edge cases in the task description rather than surfacing
them in post-delivery review.

## Part 4: Top Three Improvements

### 1. Split large integration commits into logically independent units

The WS integration commit (`e088ca4`) and the epic222 commit (`a70898e`) are
each correct and complete, but each bundles multiple independent concerns:
Express route + Three.js client modules + E2E test in one; world-state service
+ DB schema + frontend in another. The correct approach for the next equivalent
task is four commits: (a) backend route + types; (b) DB schema if applicable;
(c) frontend client changes; (d) E2E or testkit assertions that verify the
integration. This makes each unit independently revertable and makes `git
bisect` useful if a frontend regression appears after a backend refactor. The
commit messages are already strong — the split would preserve their quality
while making the history more navigable.

### 2. Include infrastructure changes in a dedicated preparatory commit

The CI workflow and git hooks added in `e088ca4` were valuable additions, but
their presence in a feature commit obscures both the feature (WS integration)
and the infrastructure change (CI enforcement). The better practice is a
separate preceding commit — `chore(ci): add CI workflow + pre-commit hooks` —
that makes CI operational before any feature work lands. This ordering also
means the CI validation is in place before the feature under development is
committed, rather than being set up in the same commit as the feature it will
gate.

### 3. Verify conditional behaviours against all relevant states before submitting

The `completedAt: null` fix was a single-line correction — the original code
set `completedAt` unconditionally, which returned a non-null timestamp for
jobs in `pending`, `evaluating`, and `awaiting_work_payment` states. A simple
pre-submission check — reading the job state machine and listing the five
states explicitly, then verifying which fields are defined in each — would have
caught this without a follow-up commit. For any API field that depends on job
state, the pre-submission step should be: enumerate all states in the state
machine, verify the field value is correct for each, then commit. The testkit
already exercises all states; running it before submission is the fastest
complete verification.
