Project

Verdict: APPROVED

Re-review after previous false positives. All backing notes confirmed to exist. Scope is solid.

Template Completeness

  • [x] Type -- Feature
  • [x] Lineage -- Sub-ticket of #7, depends on #8
  • [x] Repo -- forgejo_admin/twitch-2k-wager
  • [x] User Story -- developer story for schema foundation
  • [x] Context -- references arch-domain-twitch-2k-wager
  • [x] File Targets -- 3 files (db.ts, schema.sql, types.ts)
  • [x] Acceptance Criteria -- 8 items, all testable
  • [x] Test Expectations -- schema apply + connection test
  • [x] Constraints -- pg package, match arch exactly
  • [x] Checklist -- standard 3-item
  • [x] Related -- parent, dependency, arch note

Traceability

  • [x] story:game-status label -- present on board item #795
  • [x] story note verified -- story-twitch-2k-wager-game-status (id 1159) exists, listed in project-twitch-2k-wager user-stories table
  • [x] arch:domain-twitch-2k-wager label -- present on board item #795
  • [x] arch note verified -- arch-domain-twitch-2k-wager (id 1154) exists with full ER diagram
  • [x] Forgejo issue -- forgejo_admin/twitch-2k-wager#9, state: open

File Targets

  • [x] src/lib/db.ts -- creation target. Repo currently has only README.md. Parent directory will exist after #8 (scaffold) creates src/ structure. Valid.
  • [x] src/lib/schema.sql -- creation target. DDL for 5 tables matching arch-domain-twitch-2k-wager ER diagram.
  • [x] src/lib/types.ts -- creation target. TypeScript types mirroring schema.
All targets are specific enough for an agent to act on without guessing. Schema source of truth is arch-domain-twitch-2k-wager.

Repo Placement

OK. Issue filed on forgejo_admin/twitch-2k-wager, all file targets are in the same repo. Single-repo ticket. No cross-repo scope.

Dependencies

  • [x] #8 (SvelteKit scaffold + Dockerfile) -- pending (backlog). Sequential dependency documented in Lineage. Must complete before this ticket executes. Not a scope problem -- intentional ordering.
  • [x] arch-domain-twitch-2k-wager -- satisfied. Note exists with full ER diagram that defines all 5 tables.
  • [x] CNPG cluster -- satisfied. Service onboarding (#1) is closed/merged (PR #54 pal-e-services).

Acceptance Criteria

8 criteria, all agent-verifiable:
  • Schema-to-arch matching: agent can diff created schema.sql against arch-domain-twitch-2k-wager ER diagram. Columns, types, FKs, enums all explicitly specified in both the AC and the arch note.
  • Connection test: concrete SQL command (SELECT 1) with real env var (DATABASE_URL).
  • All amounts in cents: verifiable by reading schema.sql column types (integer).
  • No ambiguous language. Every criterion is testable.

Blast Radius

  • New project, new schema. No existing consumers.
  • CNPG cluster is shared infrastructure but schema is project-scoped (playme2k database).
  • No sibling services share these tables.
  • Rollback: DROP TABLE on all 5 tables. Straightforward since no data exists yet.

Decomposition Assessment

3 file targets in 1 repo. 8 AC but all are verification checkpoints for one coherent task (define 5-table schema + connection layer + TypeScript types). The three files are tightly coupled -- schema.sql defines tables, types.ts mirrors them, db.ts connects to them. Splitting would create artificial boundaries and require coordination overhead.
  • Discrete changes: 3 (one per file). Within the three-thing limit.
  • Estimated agent time: under 5 minutes. Schema is fully defined in the arch note -- the agent is transcribing, not designing.
  • No independent subtasks that benefit from parallelization.
No decomposition needed.

Recommendation

No action needed. Ticket is ready for execution once #8 (scaffold) is complete.
