Extract subprocess execution and process contracts into @orca/process-host with explicit public entry points, independent checks, and one Node 18 compatible CommonJS runtime. Migrate application consumers and integrate package builds, dependency selection, import enforcement, and runtime resource staging.
Preserve daemon startup ownership and profile isolation, and qualify development rebuild recovery and concurrent output publication. Remove unnecessary aliases, test forwarding exports, and a duplicate output scan.
Validation: full typechecks, changed-code quality, package and artifact checks, native Windows builds/types plus 306 runtime tests, and independent native reviews.
Matched full E2E controls on original main and unchanged reviewed head both pass all 17 applicable tests (nine skips). Earlier intermittent E2E failures are documented in the PR; no assertions were weakened. The final combined-tree audit preserves both branches with no import-boundary violations.
* fix(opencode): read the binder's session store on the foreign SQLite reader worker (STA-9122)
Before: the OpenCode session binder listed new sessions from opencode.db with
node:sqlite on the main thread every 60 s (and on SessionStart kicks), so a
large or contended store could stall the app the same way Cursor's did.
After: the read is a pure openCodeBinderSessions reader in
foreign-sqlite-readers/readers/, run only on the worker. The binder's
correlation, pane snapshot and process sweep stay where they were.
- The binder round awaits listSessions and re-checks its generation right
after, so a stop() during the read discards the round before it touches the
unbound map or the watermark.
- The client's in-flight dedupe key now includes the cursor, so a stale round
from before a restart cannot hand its rows to the restarted round.
- Idle teardown is per reader. The binder lane keeps its thread for 120 s,
longer than its 60 s poll, so the thread is not respawned every round.
- A timeout, crash, malformed reply or unstartable worker resolves to [] (no
sessions), the value the old read already returned on failure.
- An absent store still reads as [] without a log line, and a permission or
corrupt-file failure still logs (kept from #24577, now in the reader: it
stats the path and throws anything but ENOENT/ENOTDIR to the client's log).
- The binder lane inherits #24572's limits from the shared lane: no respawn
until a timed-out worker has exited, 2 consecutive deaths, a queue cap of
8. Its timeout stays 60 s, matching its poll.
- dispatch switches on the destructured kind, so a new kind without a case
still fails to compile.
orcad: the hook server runs there too, so orcad now ships
foreign-sqlite-reader-entry.js beside orcad.js (ORCAD_ARTIFACTS, built as an
orcad child). build-orcad runs a smoke check that starts the built worker
under the build's Node and under the pinned runtime, and does a real binder
read on a fixture DB, a Cursor read of a missing file and an OpenCode history
list. The OpenCode history scanner uses the same entry and was bundled into
orcad without it, so on orcad it always failed closed; it can now run.
Tests: reader (cursor, same-ms ids, OpenCode 2 rows, missing then created,
corrupt, inaccessible directory), retirement gate for the binder lane, dispatch
routing, client lane (rows, failure -> [], dedupe per cursor, own thread, idle
teardown default and override), binder loop with an async listSessions
(failure -> [], stop during the read), orcad path resolution through orcad's
host adapters, artifact list, and the smoke check against good, missing and
non-reading entries.
* test(opencode): cover the binder read deadline with fake timers and name the failure test accurately (STA-9122)
