feat(design): introduce design daemon — multi-board persistent server
Adds design/src/daemon.ts: a Bun.serve daemon that hosts many boards
under /boards/<id>/ instead of one server per `$D compare --serve` call.
Spawned by daemon-client (next commit); for now wired only via tests.
Endpoint table:
GET /health liveness + version + counts (unauth)
GET / index of recent boards
POST /api/boards publish; daemon derives sourceDir
from realpath(html). body sourceDir
IGNORED (Codex trust-boundary fix).
POST /shutdown graceful; refuses if active boards
exist (Codex data-loss fix)
GET /boards/<id> 301 → /boards/<id>/ (trailing slash
is load-bearing — relative URLs in
board JS resolve against pathname)
GET /boards/<id>/ render board HTML
GET /boards/<id>/api/progress state machine status (no idle reset)
POST /boards/<id>/api/feedback submit/regen; writes feedback.json
or feedback-pending.json with
boardId + publishedAt augmented in
POST /boards/<id>/api/reload swap HTML; per-board allowedDir
guard rejects traversal, directories,
out-of-allowed-dir symlinks
Lifecycle:
- 24h idle timeout (DESIGN_DAEMON_IDLE_MS for tests).
- Idle with active boards extends 1h up to 4x, then force-shuts (Codex).
- LRU cap 50 boards; evicts done before non-done; 503 when 50 non-done.
- Per-board async mutex serializes feedback POST vs reload POST.
- SIGTERM/SIGINT/uncaughtException → graceful shutdown, state file unlink.
- Stdout: DAEMON_STARTED port=<N> (the line the client parses).
Shared utilities live in design/src/daemon-state.ts: atomic state-file
write/read (mode 0o600), fs.openSync('wx') lock, isProcessAlive, cmdline
identity verification (/proc on Linux, ps on macOS), CMDLINE_MARKER
constant. Modeled on browse/src/cli.ts lock + spawn patterns.
design/test/daemon.test.ts: 30 tests, all green. Covers every endpoint,
both error paths and happy paths, cross-board feedback isolation, the
trailing-slash redirect, the directory-not-file reload rejection, LRU
preferring done over non-done, /shutdown refusal with active boards,
all path-traversal guards. Uses the exported fetchHandler in-process
(no spawn) so the suite runs in ~70ms.
design/test/daemon-tests-fixtures.ts: shared helpers — req() builder,
tmp-dir helpers, daemon reset, and a spawnDaemonForTest() helper used
by the next commit's discovery tests.
