Summary

  • Root cause: virtiofs (macOS podman machine) forwards file semantics but not Unix socket semantics. keeperd.sock appears on the Mac filesystem but connect() from the Mac host fails with ENOENT: connect ENOENT /Users/bobby/.local/run/prx/doors/keeperd.sock.
  • Fix: keeperd-room declares tcpPort: 9999; renderPodmanRun adds -p 9999:9999 and --port 9999 CMD arg; launchPod sets KEEPERD_HOST=127.0.0.1:9999 so door-kit's client uses TCP. Linux path (no tcpPort) unchanged — falls back to KEEPERD_SOCK.
  • Confirmed: l2LaunchDigest: 686c6cfd008a541725dab07655a4bd878d9cc8edc563413d409f2efbb20cae79 live on Mac.

Checklist

  1. Independent PR — TCP transport only; no bundled changes
    • Verified: 7 files: spec.ts + keeperd-room.ts + podman.ts + podman-runtime.ts + 3 test files
  2. Changed codepaths verified — targeted unit + live test
    • test/room/podman.test.ts--publish 9999:9999 + --port 9999 in CMD args
    • test/room/launch-pod.test.tsKEEPERD_HOST=127.0.0.1:9999 set during attest; env restored; Unix fallback path covered
    • Live: launchPod(pod)l2LaunchDigest: 686c6cfd... (non-null on Mac)
  3. Root cause identified — macOS virtiofs Unix socket limitation
    • virtiofs = file export only; socket connections don't cross the VM↔host boundary
  4. No duplicationkeeperTcpPort helper mirrors keeperSocketPath pattern
    • Linux production path unchanged (no tcpPort on keeperd-room in production)
  5. No unrelated changes — coverage baseline comment updated to match new line %
    • N/A

Test plan

  • bun test test/room/podman.test.ts — 33 pass
  • bun test test/room/launch-pod.test.ts — 5 pass (3 new TCP-path tests)
  • bun test test/room/podman-runtime.test.ts — 7 pass
  • launchPod(perRepoPod) live on Mac → l2LaunchDigest non-null ✓

Replace all direct zod schema object usages with the new explicit type +
parse-function surface from @bounded-systems/machine-schema@0.3.0:

- handoff/cli.ts: handoffTargetActor.safeParse → safeParseHandoffTargetActor;
  handoffTargetActor.options → HANDOFF_TARGET_ACTOR_VALUES (3 call sites)
- handoff/store.ts: handoffEnvelope.parse → parseHandoffEnvelope (4 call sites)
- derive/cli.ts: z.array(rawStateV1Schema) → z.array(z.unknown().transform(parseRawStateV1))
- machine/contracts/guards.ts: rawStateV1Schema.parse → parseRawStateV1
- machine/contracts/anchored-chain-bridge.ts: rawStateV1Schema →
  z.unknown().transform(parseRawStateV1)
- pr-state/domain_state.ts: .shape.* → z.custom<T>(); rawStateV1Schema.parse →
  z.unknown().transform(parseRawStateV1) + parseRawStateV1
- machine/work_unit.ts: update brand comment (v0.3.0 uses unique-symbol brand,
  not zod BRAND — explicit `as WorkUnitId` casts remain correct)

Dependency: @bounded-systems/machine-schema@^0.3.0 (published separately).
CI is blocked until that package is available on JSR.

…LaunchDigest on Mac) (#749)

virtiofs forwards file semantics but not Unix socket semantics: the keeperd.sock
file appears on the macOS filesystem but connections from the Mac host fail with
ENOENT. TCP tunnels around this — keeperd-room declares tcpPort: 9999, podman
publishes -p 9999:9999 and passes --port 9999 as a CMD arg, and launchPod sets
KEEPERD_HOST=127.0.0.1:9999 so door-kit's client connects via TCP instead of
the Unix socket path. launchPod falls back to KEEPERD_SOCK (Unix) when tcpPort
is absent, so the Linux production path is unchanged.
