(janitor/dead-code): remove orphaned gastown rig/town-escalation tables

[kilo-code-bot]

What was deleted

Seven orphaned Durable Object SQLite table definitions in services/gastown/src/db/tables/:

• rig-agents.table.ts
• rig-beads.table.ts
• rig-bead-events.table.ts
• rig-mail.table.ts
• rig-molecules.table.ts
• rig-review-queue.table.ts
• town-escalations.table.ts

These are leftovers from the rig→town refactor. The active schema (beads, agent-metadata, escalation-metadata, convoy-metadata, bead-dependencies, town-events, agent-nudges, org-towns, user-towns, user-rigs, rig-agent-events) is imported and instantiated in Town.do.ts, Agent.do.ts, GastownUser.do.ts, GastownOrg.do.ts and the dos/town/* sub-modules. The deleted tables are not part of that graph.

Evidence of unreachability

• No import/export ... from reference to any of the seven .table modules anywhere in the repository (checked apps/, packages/, services/, dev/, scripts/, tools/).
• No reference to any exported symbol (rig_agents, rig_beads, rig_bead_events, rig_mail, rig_molecules, rig_review_queue, town_escalations, their *Record zod schemas, createTable*/getIndexes* helpers) outside the deleted files themselves — including test files and .sql/migration/seed content.
• The createTable*() helpers are never called from any DO migration path. The live tables are wired via createTableBeads(), createTableAgentMetadata(), createTableTownEvents(), createTableRigAgentEvents(), createTableUserRigs(), createTableUserTowns(); none of the deleted tables' creators are invoked.
• No cross-contamination with the generic BeadEventType / EscalationSeverity names: the live definitions in bead-events.table.ts and escalation-metadata.table.ts are self-contained and unaffected.
• No reference in the external consumer clone (Kilo-Org/kilocode).

Dynamic and configured entry points checked

• services/gastown/wrangler.jsonc / wrangler.test.jsonc: no Durable Object binding, migration, queue, cron, RPC, or workflow references these tables.
• No drizzle.config.* or SQL migration files exist in services/gastown; the DO SQLite schema is created at runtime via createTable* only.
• No barrel/index.ts under db/tables/, and no import * as/glob/dynamic-import of the tables directory.
• gastown.worker.ts routes and handlers/* reference only the live DO stubs and live tables; town-escalations.handler.ts operates on escalation_metadata, not town_escalations.

Contract and compatibility considerations

• All packages/* in this monorepo are "private": true; these files are not published exports.
• The deleted tables are never created in DO SQLite (createTable* never called), so no persisted data, migration, rollback, or rollout dependency is affected. Deleting the type-only definitions has no runtime effect.

Validation performed

• pnpm --filter cloudflare-gastown exec tsgo --noEmit — passes (baseline and after deletion).
• pnpm --filter cloudflare-gastown test — 22 files / 323 tests pass.
• pnpm -w exec oxlint --config .oxlintrc.json services/gastown/src — 0 warnings, 0 errors.
• Post-deletion grep confirms zero remaining references to any deleted symbol.

Code Review Summary

Status: No Issues Found | Recommendation: Merge

Executive Summary

Deletion-only PR removing seven unused gastown *.table.ts definitions; independent repository-wide searches confirm none of the deleted modules, symbols, table names, or createTable*/getIndexes* helpers are referenced anywhere in code, config, SQL, or tests, so removal has no runtime effect.

Files Reviewed (7 files)

• services/gastown/src/db/tables/rig-agents.table.ts (deleted)
• services/gastown/src/db/tables/rig-beads.table.ts (deleted)
• services/gastown/src/db/tables/rig-bead-events.table.ts (deleted)
• services/gastown/src/db/tables/rig-mail.table.ts (deleted)
• services/gastown/src/db/tables/rig-molecules.table.ts (deleted)
• services/gastown/src/db/tables/rig-review-queue.table.ts (deleted)
• services/gastown/src/db/tables/town-escalations.table.ts (deleted)

Verification Notes

• No import, re-export, dynamic import, barrel, glob, or test reference to the seven module paths or their exported symbols remains anywhere in the repo.
• The runtime DO schema (Town/Agent/GastownUser/GastownOrg) creates only beads, bead_events, bead_dependencies, agent_metadata, review_metadata, escalation_metadata, convoy_metadata, rigs, agent_nudges, town_wasteland_connections, town_events, rig_agent_events, user_towns, user_rigs, org_towns; none of the seven deleted tables is created or queried.
• Same-named symbols (BeadType, BeadStatus, BeadEventType, EscalationSeverity, MoleculeStatus, ReviewStatus, AgentRole, AgentStatus) are defined and imported from separate live modules, so bead-events.table.ts and escalation-metadata.table.ts are unaffected.
• The only remaining mentions of the deleted table names are descriptive prose in .plans/gastown-town-centric-refactor.md, which is documentation and does not make the modules reachable.
• No .sql migration/seed files exist under services/gastown; wrangler configs register DO classes only and contain no table DDL.
