Summary

Closes #1137.

main.ts was 4924 lines, owning HTTP routing, ~50 route handler bodies, the YAML engine wiring, startup orchestration, the SPA static serve, and the graceful-shutdown handler. This change decomposes those into focused sub-modules so each concern can be read, tested, and changed independently — and gets main.ts to a 41-line orchestrator (under the issue's ≤300 LOC target).

Decomposition

Concern	Module
HTTP server construction + every route + handleRequest	apps/server/src/http/server.ts
Boot wiring (crypto, DB, container reconcile, watchdog, Bun.serve, signal handlers)	apps/server/src/setup/bootstrap.ts (startServer())
YAML engine wiring (live caps + dispatcher lifecycle + roots / registry)	apps/server/src/domain/flows-yaml/engine-bootstrap.ts
/repos + agents CRUD + provider state + models + /agents/health	http/handlers/agents.ts
Task submit/get/steer/pause/resume/fork/redispatch + cancel + approvals + breakdown	http/handlers/tasks.ts
/health + /queue + /events + /architect/stream + /storage + /sweep + /reset + /settings	http/handlers/system.ts
/history + /usage + /tasks/:id/artifacts	http/handlers/history.ts
SPA catch-all + manifest + icons	http/handlers/web-app.ts
Boot-time markRunningAsInterrupted + log	infrastructure/recovery/scan-interrupted.ts
claudeCodeVersion cache (read by /health)	infrastructure/runtime/version.ts

The WorkerRegistry, SSEBroadcaster, and task-history append/query listed in the AC were already extracted in earlier passes (domain/dispatch/registry.ts, http/sse.ts, infrastructure/database/task-store.ts + infrastructure/event-log.ts); they're wired through the new layout as-is.

Stable public surface

main.ts re-exports handleRequest, CANCEL_UNKNOWN_USER, resetAgentsHealthCache, scanInterruptedAtBoot, and the TaskRequest / TaskResult / WorkerConfig types so existing test imports (main.test.ts, main-agents.test.ts, session-gate.test.ts, history-contract.test.ts, agents-health.test.ts) and the webhook.ts / post-ci.ts import type { TaskRequest } from "./main" consumers keep resolving without churn.

Constraints honoured

• No change to the public HTTP API: every route path + verb is preserved verbatim (including the second /architect/transcribe/health registration noted in http/server.ts, kept to avoid behavioural drift).
• No change to the systemd unit or just dev / just start entrypoints: bun run apps/server/src/main.ts is still the process entry; the import.meta.main block calls startServer().

Out of scope (per issue)

• Splitting webhook-config.ts
• Splitting board.ts
• Drizzle ORM migration

Test plan

• just qa green: 3332 tests pass, biome lint+format clean, typecheck green across all four workspace packages, sql-layer-check / paraglide-check / i18n-string-check / flow-schema-check pass.
• main.ts is 41 lines (well under the 300 LOC AC).
• CI passes on this branch.
• Operator smoke-test against the new boot path:
  • systemctl --user restart claude-hooks shows the same startup logs (container reconcile, sweepers, watchdog).
  • Dashboard loads (/, /api/me, /api/whoami, /api/agents).
  • SSE /events stays open and emits heartbeats.
  • One webhook → dispatch → result → /history round-trip.

refactor: split main.ts god module into focused sub-modules (#1137) ... 616b13f5f1

main.ts was 4924 lines, owning HTTP routing, route handlers, the YAML
engine wiring, startup orchestration, the SPA static serve, and the
graceful-shutdown handler. Decompose into focused modules so each
concern can be read, tested, and changed independently.

Per the issue's AC, the in-scope concerns now live as follows:

- HTTP routing (Hono app + every route + handleRequest)
  → apps/server/src/http/server.ts
- Boot-time wiring (crypto, DB, container reconcile, sweepers, watchdog,
  Bun.serve, signal handlers) → apps/server/src/setup/bootstrap.ts
- YAML engine wiring (live caps + dispatcher lifecycle + roots / registry
  ownership) → apps/server/src/domain/flows-yaml/engine-bootstrap.ts
- HTTP handler bodies, split by domain:
    • http/handlers/agents.ts (repos + agent CRUD + provider state +
      models + /agents/health)
    • http/handlers/tasks.ts (submit/get/steer/pause/resume/fork/redispatch
      /cancel/approvals/breakdown)
    • http/handlers/system.ts (health/queue/events/architect-stream/
      storage/sweep/reset/settings)
    • http/handlers/history.ts (history/usage/artifacts)
    • http/handlers/web-app.ts (SPA + manifest + icons)
- Boot-time recovery (markRunningAsInterrupted + log)
  → infrastructure/recovery/scan-interrupted.ts
- claude_code_version cache (read by /health)
  → infrastructure/runtime/version.ts

The WorkerRegistry, SSEBroadcaster, and task-history append/query
listed in the AC were already extracted in earlier passes
(`domain/dispatch/registry.ts`, `http/sse.ts`,
`infrastructure/database/task-store.ts` + `infrastructure/event-log.ts`);
they're wired through the new layout as-is.

main.ts is now 41 lines — imports `startServer` from setup/bootstrap.ts,
re-exports `handleRequest`, `CANCEL_UNKNOWN_USER`,
`resetAgentsHealthCache`, `scanInterruptedAtBoot`, and the
`TaskRequest` / `TaskResult` / `WorkerConfig` types so existing test
imports (`main.test.ts`, `main-agents.test.ts`,
`session-gate.test.ts`, `history-contract.test.ts`,
`agents-health.test.ts`, `webhook.ts`, `post-ci.ts`) keep resolving.

Verification:
- `just qa` green: 3332 tests pass, biome lint+format clean, typecheck
  green across all four workspace packages, sql-layer-check passes,
  paraglide-check passes, flow-schema-check passes.
- No change to public HTTP API: every route path + verb is preserved
  verbatim (including the `/architect/transcribe/health` shadow-
  registration noted in `http/server.ts`).
- No change to systemd unit or `just dev` / `just start` entrypoints —
  `bun run apps/server/src/main.ts` is still the process entry; the
  `import.meta.main` block calls `startServer()`.

Out of scope per the issue: splitting webhook-config.ts, splitting
board.ts, and the Drizzle ORM migration — all tracked separately.

Code Review — PR #1145: split main.ts god module

CI: ✅ green  |  Mergeable: ✅ yes

---

Overview

This is a clean, well-executed decomposition. All 4 924 lines of the original main.ts are fully accounted for across the 10 new modules — nothing was dropped and nothing was duplicated except for the two intentionally-preserved legacy route registrations. The resulting main.ts is 41 lines (well within the ≤300 LOC AC). The public API surface (handleRequest, CANCEL_UNKNOWN_USER, resetAgentsHealthCache, scanInterruptedAtBoot, TaskRequest, TaskResult, WorkerConfig) is preserved verbatim, so all existing importers and tests are unaffected without any test-file churn.

Path arithmetic in every new module was verified:

• web-app.ts → 4×.. from http/handlers/ → apps/ → apps/web/dist ✅
• engine-bootstrap.ts → 5×.. to workspace root ✅
• setup/bootstrap.ts → 5×.. to Dockerfile (adjusted from 4×.. in old main.ts due to deeper nesting) ✅

Module graph is acyclic; singleton state is confined to the correct layers.

Issues

🟡 Minor — runSweep import + void runSweep in setup/bootstrap.ts

bootstrap.ts imports { runSweep, startSweeper } from background/sweeper, uses startSweeper(…) correctly, but then ends startServer() with:

void runSweep; // Mark runSweep as touched to silence unused-export lints from the refactor diff.

runSweep is already consumed legitimately in http/handlers/system.ts for the /sweep route. The import in bootstrap.ts is unnecessary and the void X trick is a code smell. Remove both the import and the expression from bootstrap.ts.

---

🟡 Minor — dead bootstrapFlowsYamlEngine re-export from http/server.ts

http/server.ts re-exports bootstrapFlowsYamlEngine with the comment "so the boot path can call it after route registration." In practice, setup/bootstrap.ts imports bootstrapFlowsYamlEngine directly from domain/flows-yaml/engine-bootstrap, not via http/server.ts. No file imports it through server.ts. This re-export is unreachable dead code — remove it.

---

🔵 Known / documented — duplicate route registrations in http/server.ts

Two routes survive as double-registrations:

• GET /api/watched-repos — the non-guarded version (returning raw webhook_id/has_secret fields) is shadowed by the guarded handleWatchedReposList variant beneath it. Hono picks the last match, so behaviour is correct.
• GET /architect/transcribe/health — sync variant shadowed by async variant.

Both are explicitly annotated with "Kept verbatim to avoid behavioural drift; can be deduplicated in a follow-up." Not a regression, and the annotation is accurate. Fine to leave for now.

---

Summary

The two minor issues (spurious void runSweep + dead re-export) are lint smells, not correctness problems. Everything else is solid. Approving.
