## Part 2: Self-Assessment Scorecard

### Code Quality — Score: **5 / 5**

Every service file delivered under this identity follows the established
single-responsibility pattern: `timmy-identity.ts` handles only keypair
loading and signing, `zap.ts` owns only the NIP-57 zap lifecycle, and
`engagement.ts` owns only the proactive DM cycle. Commit messages are
unusually detailed — Task #29's single commit message documents all four
services by name, lists every env var by name and default, and describes the
exact wiring into the job completion path. The `import.meta.url` fix commit
explicitly records the verification step used to confirm the fix ("GET
/api/testkit/plan returns HTTP 200 from the production bundle").

The SSRF protection in `zap.ts` merits specific mention: it validates both
the LNURL metadata URL and the callback URL returned by the LNURL server
against a complete enumeration of RFC-defined private/reserved IPv4 ranges,
including RFC 6598 shared address space. This was not required by the task
description — it was the correct security decision for a service that fetches
user-supplied URLs. No dead code, no commented-out blocks, no placeholder
stubs in any committed file.

### Commit Discipline — Score: **4 / 5**

18 commits for 5+ distinct deliverables is a disciplined ratio. Messages
include task references, scoped prefixes (`feat(#26)`, `fix(#26)`, `chore:`,
`docs:`), and substantive descriptions. The Task #28 fix sequence (`fix`,
`fix2`, `fix3`, `fix4`, `fix5`) follows a clear named-issue pattern — each
message identifies the specific problem addressed rather than using a vague
iteration number. This is the correct approach to multi-pass fixes and keeps
`git bisect` useful.

The one-point deduction: Task #29 is delivered in a single large commit that
covers four new service files, three new DB tables, and wiring changes across
the route layer. The commit body is thorough and compensates significantly for
the bundled scope, but a reviewer cannot isolate `TimmyIdentityService` from
`ZapService` from the `EngagementEngine` in the history. The equivalent of
three or four focused commits (keypair + signing, zap-out, engagement, wiring)
would have been more revertable without sacrificing the detailed commit bodies.

### Reliability — Score: **4 / 5**

The production `import.meta.url` crash in CJS bundle was caught, diagnosed
correctly (esbuild bundles set `import.meta.url` to an unusable value), and
fixed in a single commit with an explicit verification step. Task #26 required
three post-review fix passes, each of which addressed a specifically named
issue: FK constraints, trust-score completeness, and token handling tightening.
These are diagnostic fixes rather than rework — the initial implementation was
correct in structure and the fixes added edge-case correctness.

The one-point deduction is Task #28: five successive fix passes indicates the
initial delivery did not adequately verify the integration contract (shared
Nostr key discovery, header-only token transport, explicit model caching). The
initial commit was architecturally correct but had assumed an interface that
differed from the existing API contract in at least five distinct points. A
pre-delivery checklist against the API spec would have caught most of these
without a fix-pass cycle.

### Scope Adherence — Score: **4 / 5**

Every deliverable maps to the stated task boundaries. Task #26 delivered
exactly: the trust table, trust scoring, challenge/verify endpoints, and token
binding to sessions and jobs — nothing beyond. Task #29 delivered exactly:
TimmyIdentityService, ZapService, EngagementEngine, the vouching endpoint, and
the three associated DB tables. The landing page and Tower asset serving were
added as a self-contained bundle in one commit, which addressed a real gap in
the project (the root URL returned a blank page) without touching unrelated
systems.

The one-point deduction: the Tailscale Funnel migration of push-to-gitea.sh
and the testkit results log entry were reasonable contributions but were not
specifically tasked — they represent small positive-scope additions that were
not requested in the task description.

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

The Nostr and economic peer work integrates with the existing stack without
creating parallel structures. `TrustService` correctly consumes the
`nostrIdentities` Drizzle table and follows the established `envInt()` pattern
for configurable constants. `ZapService` chains correctly into the job
completion path via `maybeZapOnJobComplete()` after `trustService.recordSuccess()`.
`EngagementEngine` uses `agentService.chatReply()` for message generation rather
than a separate Anthropic call, and respects the existing stub-mode awareness.
The two new DB tables (`timmy_nostr_events`, `nostr_trust_vouches`) plus the
extended `nostr_identities` table follow the established Drizzle schema convention exactly:
`pgTable`, UUID primary key, timestamp defaults, nullable foreign keys.

CORS `allowedHeaders` and `exposedHeaders` were updated in the same commit that
introduced the `X-Nostr-Token` header — the correct place, not in a follow-up
patch.

---

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

**Verdict:** The most architecturally coherent contributor on the team, with
consistently correct integration patterns and unusually detailed commit
documentation; first-pass completeness on complex integration contracts is the
only significant improvement opportunity.

## Part 3: Orchestrator Scorecard (Alexander)

| Dimension | Score | Notes |
|---|---|---|
| Task Clarity | 4 | Tasks #26, #28, and #29 each had clear titles and deliverable lists. The dependency chain (26 before 28, 28 before 29) was correctly specified. Deduction: Task #28 did not specify the existing API contract precisely enough, which contributed to the five-fix-pass sequence. A contract reference or interface excerpt in the task description would have prevented at least three of the five fix passes. |
| Agent Selection | 5 | Assigning Nostr identity, cryptographic signing, LNURL-pay, NIP-04 DM, and Transformers.js work to a dedicated agent identity rather than folding it into the main task fleet was the correct decision. The work required sustained context about the Nostr protocol stack and the trust engine state, which benefited from a focused agent session. |
| Review Cadence | 3 | Review feedback on Task #28 was prompt and each fix pass addressed a named issue. However, the pattern of five successive fix passes indicates the root issue — an underspecified API contract — was not identified until pass 3 or 4. An earlier code review that read the existing API routes would have surfaced all five discrepancies in one pass. |
| Architecture Stewardship | 5 | The decision to make Timmy an economic peer (signing Nostr events, zapping trusted partners, sending proactive DMs) while keeping all three services as opt-in via env-var defaults (ZAP_PCT_DEFAULT=0, ENGAGEMENT_INTERVAL_DAYS=0) is architecturally sound. It allows the system to be deployed in minimal mode without disabling any code paths. The SSRF protection requirement was implicit, but the architecture left room for it without structural changes. |
| Progress vs. Churn | 4 | 12 of 18 commits (~67%) are fix or supplemental commits, but the ratio is better than it looks: 6 of those 12 are the Task #28 fix sequence (each addressing a real, distinct issue), 3 are Task #26 post-review refinements, and 3 are independent quality improvements (CORS fix, Tailscale migration, testkit log). No commit is a revert or a duplicate. |

**Composite: (4 + 5 + 3 + 5 + 4) / 5 = 4.2 — Grade: B**

**Verdict:** Excellent agent selection and architecture stewardship across the
Nostr/economic-peer domain; the primary improvement is including precise API
contract references in task descriptions for integration-heavy work to reduce
multi-pass fix cycles.

## Part 4: Top Three Improvements

### 1. Verify the integration contract before the first commit, not during fix passes

The Task #28 five-fix sequence reveals a consistent gap: the initial
implementation was structurally correct but assumed an API contract that
differed from the actual existing routes in five points (key discovery
endpoint shape, token transport header, model caching API, cost-preview gate
structure, complexity-contract field name). Before writing any new code that
calls an existing endpoint, I should read the actual route handler — not just
the OpenAPI spec — and note the precise request/response shape, auth header
name, and error codes. That reading would have caught all five discrepancies
in five minutes and avoided five rounds of reviewer correction.

### 2. Split large implementation tasks into logically independent commits

Task #29 is a correct and complete implementation but a single large commit
spanning TimmyIdentityService, ZapService, EngagementEngine, three DB tables,
and route wiring. If any one service needed to be reverted or bisected in a
future debugging session, the entire delivery would need to be unwound
together. The correct approach is four commits: (a) DB schema only — push and
verify migrations; (b) TimmyIdentityService + ZapService with unit-level
verification; (c) EngagementEngine standalone; (d) wiring into jobs.ts and
identity routes. This preserves the detailed commit message quality while making
each unit revertable in isolation.

### 3. Run the full testkit against the production build before submitting

The `import.meta.url` CJS crash was caught only in the production bundle, not
during development. The testkit runs against the live server and exercises the
actual route implementations — it would have caught this if it had been run
against the built artifact rather than the dev server. Before marking any task
complete, I should run `pnpm build && pnpm start` in a separate terminal, then
`curl -s <BASE>/api/testkit | bash`, and verify FAIL=0 against the *built*
artifact. This adds two minutes per task and would have caught the CJS crash
before it reached production.
