Current T3 Code runs only its newer engine and keeps its data in statev2.sqlite. Swarmail still carried code for the old engine: a fallback to the old state.sqlite database, old-format SQL queries, and a t3-v1-steer wake target that posted to a route current T3 no longer has. None of it can work against a current T3 install, so this removes it.

What changes:

  • Swarmail reads only statev2.sqlite. While T3 is still creating that file on its first start and it has no thread tables yet, Swarmail sees no threads, and pr-sessions says "local T3 store has no thread tables yet".
  • The t3-v1-steer wake target is gone. A configuration that still names it fails when it loads, with: "target type t3-v1-steer was removed: current T3 Code runs only its V2 engine, which has no V1 route; use t3-v2-queue".
  • Docs (wake-bridges, usage, pr-sessions) no longer describe the old engine. The changelog notes the removal.
  • Tests: three tests that only covered the old engine are deleted, the automatic T3 wake tests now use new-engine fixtures, and a new test checks that a t3-v1-steer configuration fails at load and names its replacement.

Checks: bun run check passes, and bun test gives 1295 pass, 7 skip, 0 fail.


Summary by cubic

Removes the t3-v1-steer wake target and all T3 Code V1 store support. Current T3 Code runs only its V2 engine, so the old bridge failed its thread check and could never deliver.

  • Swarmail now reads only statev2.sqlite; a store T3 is still creating has no thread tables yet, so pr-sessions reports that instead of "T3 V1 is unsupported".
  • Configurations naming t3-v1-steer fail at load with a message directing them to t3-v2-queue. A bridge switching targets must stop the old bridge and discard its saved state, which binds to the old destination, before starting it again.
  • T3 thread discovery now requires exactly one thread whose provider and native session ID match. Docs, changelog, and tests cover the removal.

Written for commit 0408443. Summary will update on new commits.

Summary by CodeRabbit

  • Breaking Changes
    • The t3-v1-steer wake target is no longer supported. Configurations using it fail at startup; switch to t3-v2-queue.
    • T3 thread discovery and session tools now rely on the V2 database. If it is missing or not ready, no threads are found; pr-sessions exits with an error.
  • Documentation
    • Updated setup and usage guidance to reflect supported wake targets and T3 thread discovery through provider and native IDs.

Current T3 Code runs only its V2 engine. It keeps its data in
statev2.sqlite and has no /api/orchestration/dispatch route or
thread.turn.start command, so a t3-v1-steer bridge failed its thread
check and could not deliver.

- t3StatePath returns only statev2.sqlite; the state.sqlite fallback and
  the V1 queries in t3ThreadId, t3Threads and automatic wake selection
  are gone. A statev2.sqlite that does not yet have T3's thread tables
  (T3 is still creating it) holds no threads; isT3V2 is renamed
  t3StateReady to say that.
- The t3-v1-steer adapter, its snapshot check and the T3_TYPES list are
  removed. wake-bridge, wake-auto-t3 and credential rotation reject a
  configuration naming t3-v1-steer with a message that says it was
  removed and to use t3-v2-queue.
- pr-sessions reports a store without thread tables instead of "T3 V1 is
  unsupported", and its coverage limits no longer mention V1.
- Tests that built V1 databases now use the V2 fixtures; the automatic
  supervisor quarantine and port-follow tests drive a V2 target. Tests
  of V1-only behavior are deleted.
- Docs and the changelog describe the change.

📝 Walkthrough

The pull request removes T3 V1 wake-target support and older-database lookup paths. T3 integrations now use statev2.sqlite and V2 thread data. Configuration rejects t3-v1-steer, and automatic enrollment and discovery use V2 projections.

Changes: T3 V2 migration

Layer / File(s) Summary
V2 state lookup and readiness
src/t3-state.ts, src/pr-sessions.ts, test/register-hook.test.ts, test/wake-backend.test.ts, test/wake-t3-backend.test.ts, test/wake-credentials.test.ts, docs/usage.md, docs/pr-sessions.md, CHANGELOG.md
State lookup now uses statev2.sqlite and V2 provider-thread references. Lookup returns no threads when the V2 thread table is absent. Session discovery text, coverage text, changelog, and related tests reflect the V2 database behavior.
V1 wake target removal
src/wake-target.ts, src/wake-bridge.ts, src/wake-credentials.ts, test/bridge-bridge.test.ts, test/wake-credentials.test.ts, docs/wake-bridges.md, scripts/configure-hooks.ts
The t3-v1-steer target and adapter are removed. Configuration loading rejects that target and directs users to t3-v2-queue. Bridge and credential tests cover the updated target behavior.
V2 automatic enrollment and delivery
src/wake-auto-t3.ts, test/wake-auto-t3.test.ts, docs/wake-bridges.md
Automatic enrollment and thread discovery use the V2 projection when T3 state is ready. Configuration and tests use t3-v2-queue, V2 thread state, and websocket delivery receipts.

Full details: Description check

Explanation

The description explains the motivation, behavior changes, documentation updates, tests, and reported validation results. It covers the required changelog and development-check information, with no private credentials or local paths identified.

Full details: Suppressions Explained

Explanation

The pull-request diff adds no lint, type-check, or formatter suppression directives. It adds no relevant ignore configuration entries. Added expect(...) test assertions and ordinary comments are not suppression directives.

Full details: Interface Changes Documented

Explanation

The pull request does not add, remove, or rename an MCP tool or argument, a swarmail command or flag, or an environment variable. It changes T3 target configuration and removes the t3-v1-steer adapter, which are outside this check. The changed docs/usage.md and CHANGELOG.md also document the T3 interface change.

- Around line 372-374: Clarify the thread-discovery sentence so it requires
exactly one T3 thread whose provider and native session ID match the current
session; state that no matches or multiple matches make discovery fail before
describing the fallback.

Review comments at @src/wake-bridge.ts:
- Line 53: Update the CHANGELOG with a migration note explaining that changing
target.type does not update the saved bridge binding, so an existing t3-v1-steer
journal is rejected by rejectRemovedTargetType before pending delivery; point
readers to the existing state guidance in docs/wake-bridges.md.

Review bots: CodeRabbit fully reviewed df35ae9 (2 minor findings, both fixed in 0408443 and confirmed by CodeRabbit). It skipped 0408443 as "Review rate limited" (its one included review this hour was used); that commit changes only CHANGELOG.md and docs/usage.md. Greptile's trial reached its 50-credit limit; cubic reached its line limit. Merging on passing CI (check, windows) at 0408443.
