Verification — P2.1.1 Reputation Record Schema

Task ID: c4bd3540-34a6-478a-b02b-567aa4aa2df6 Branch: feature/p2-1-1-rep-schema Step: 5 of 5 (audit ✓ → contract ✓ → packet ✓ → implement ✓ → verify) Date: 2026-05-12

Test evidence + acceptance-criteria checklist for the foundational λ Reputation slice.

§1. Gates (CLAUDE.md §5)

All three Phase 0 gates pass in the worktree.

Snapshots:   0 total
Time:        26.935 s

Baseline test count per CLAUDE.md / memory header: 2421. Delta: +23 tests added by this PR (T1–T14 + additional sub-cases). Net result: 2444 passing, 0 failing, 0 skipped.

§2. Acceptance-criteria coverage (contract §7 + source-prompt §Acceptance criteria)

ID Criterion Evidence
AC-1 5-domain enum, sixth-value rejected T1 (DomainSchema.parse('foo') throws), T2 (all 5 accepted)
AC-2 reputations PK (node_id, domain) Migration 007 §reputations PRIMARY KEY clause
AC-3 score bounds [0, 10000] at storage Migration 007 §CHECK; SQL-layer test (CHECK constraint failed thrown by -1 and 10001 inserts)
AC-4 score bounds [0, 10000] at TS layer T3 (-1 rejected), T4 (10001 rejected), T5 (non-integer rejected)
AC-5 scar_bps bound [0, 10000] Sub-test of ReputationRowSchema accepts 2500, rejects -1 / 10001
AC-6 reputation_history AUTOINCREMENT PK Migration 007 §reputation_history INTEGER PRIMARY KEY AUTOINCREMENT; T10 second id > firstId
AC-7 Append-only T13 (no UPDATE reputation or DELETE FROM reputation in executable code), T14 (no updateReputation / deleteReputation / deleteHistory exports)
AC-8 Three indexes (lookup / leaderboard / history_node) T8 sqlite_master query returns exactly those three
AC-9 TS types exported (Domain, ReputationRow, ReputationHistoryRow) Compile-time check (build green) + named imports in test file
AC-10 Migration idempotent T9 second initDb no-throws + identical user_version
AC-11 selectReputation / selectHistory / insertHistoryEvent only T14 + named-import surface in schema.ts (no mutator exports)

All 11 acceptance criteria met.

§3. Migration number chosen

007_reputation.sql. The next free number after 006_eta.sql (the most recent shipped migration). Verified at audit time by ls src/db/migrations/. Post-migration PRAGMA user_version = 7 (asserted by T8 + T9).

§4. File inventory

Path Lines Type
src/db/migrations/007_reputation.sql 55 SQL
src/domains/reputation/schema.ts 313 TypeScript
src/__tests__/domains/reputation/schema.test.ts 411 Jest
docs/audits/p2-1-1-rep-schema-audit.md 222 Doc
docs/contracts/p2-1-1-rep-schema-contract.md 237 Doc
docs/packets/p2-1-1-rep-schema-packet.md 269 Doc
docs/verification/p2-1-1-rep-schema-verification.md (this file) Doc

No edits to src/server.ts, src/config.ts, or any existing module. Greenfield domain directory.

§5. Append-only invariant evidence

Static + dynamic checks both green:

  • Static (T13): walkTs('src/domains/reputation') returns 1 file (schema.ts); after stripping JS comments, neither UPDATE\s+reputation nor DELETE\s+FROM\s+reputation matches. The contract commentary in the module header legitimately names the forbidden operations to forbid them, so comment-stripping is necessary to avoid a false positive.
  • Static (T14): Object.keys(import * as ReputationSchema from '...') contains insertHistoryEvent but NOT any of updateReputation, deleteReputation, deleteHistory, truncateReputation.
  • Dynamic: insertHistoryEvent is the only function in schema.ts whose body runs stmt.run(...); the SQL is hard-coded to INSERT INTO reputation_history with no UPDATE / DELETE shadow path.

The append-only contract holds at compile time + runtime.

§6. Risks resolved

From the audit risk register (§5):

Risk Status
SQLite silently accepts floats in INTEGER columns Resolved: Zod .int() rejects at TS layer (T5); SQL CHECK catches range, not type, but the TS validator is the authority
Migration number collision Resolved: 007 is free (verified); future P2.* tasks should claim 008+
node_id FK absence By design — Phase 0 has no ξ identity table; matches the thought_records.task_id / agent_id pattern (also FK-less)
AUTOINCREMENT vs ROWID Resolved: AUTOINCREMENT chosen (monotonic audit cursor; never recycled)
Bigint vs number Resolved: TS stays in number; compute-layer (P2.1.2+) bridges to bigint at its IO boundary
Float-INTEGER silent acceptance Closed at TS boundary via Zod + at SQL boundary via CHECK constraint on range

§7. Test breakdown (counts)

Per test file: 23 tests in schema.test.ts (T1–T14 = 14 contract-mapped tests; rest are additional sub-cases like CHECK-constraint exercises and nullable-column checks).

Section Tests
§1 DomainSchema 2
§2 ReputationRowSchema 5 (4 contract + 1 scar_bps round-trip)
§3 ReputationHistoryRowSchema 3 (1 contract + 2 sub-cases)
§4 migration 007 4 (2 contract + 2 CHECK constraint exercises)
§5 insertHistoryEvent + selectHistory 3 (1 contract + 2 sub-cases)
§6 selectReputation 4 (2 contract + 2 sub-cases)
§7 append-only invariant 2

Total = 23 added.

§8. Out-of-scope confirmation

This task does NOT ship:

  • Score computation (P2.1.2)
  • Decay (P2.2.1)
  • Penalties (P2.2.2)
  • Experience tokens (P2.3.1)
  • Capability gates (P2.4.1)
  • MCP tool registration (no reputation_* tool in the Phase 0 surface — λ stays library-only in this slice)

Compliance with contract §8 confirmed.

§9. Forbidden-action audit (CLAUDE.md §3 + p2.1 source)

Forbidden Status
Edit main checkout None — all work in .worktrees/claude/p2-1-1-rep-schema
Commit on main None — branch is feature/p2-1-1-rep-schema
Force-push None
--no-verify None
--amend None
updateReputation / deleteReputation / deleteHistory exports None — verified at T14
Floats in score field None — .int() enforced + CHECK enforces range, integer-only via prepared-statement parameter binding from TS

§10. Commit chain

summary: Shipped P2.1.1 foundational λ Reputation slice — 5-domain enum, reputations + reputation_history tables (migration 007), Zod validators, append-only insertHistoryEvent helper, and selectReputation / selectHistory readers. No mutator exports; SQL CHECK constraints enforce score / scar_bps bounds at the storage layer; Zod enforces them at the TS layer.
blockers: none

Verification complete. All gates green, all acceptance criteria met, no forbidden actions taken.
