Current deterministic status: Threaded Mode implementation, native typing/activity status, regression coverage, docs/context reconciliation, typecheck, full tests, pack check, audit, Domain DAG validation, context validation, native Windows classic↔Threaded Mode upgrade/downgrade smoke, and live post-reload leader/follower prompt routing, follower Active parity, and unbound reroute/restore smoke are green. This backlog intentionally tracks only release-relevant remaining work: 0.19.0 release preparation, evidence-gated Telegram client/runtime follow-ups, and upstream Pi API blockers.
Context: deterministic coverage protects promoted follower thread preservation, and the latest live Linux smoke closed the reload routing, follower Active, and reroute/restore regressions. Keep one explicit live check for promoted-follower reload identity unless that exact path is covered in the release smoke pass.
Open work:
- Close leader → follower promotes →
/reloadpromoted leader preserves the same Telegram thread identity.
Done when: promoted-follower reload identity has live Telegram evidence or is deliberately deferred out of the hotfix scope.
Context: Native Windows smoke on the WIP dev build now passes for classic mode, classic ownership handoff, hot upgrade to Threaded Mode, leader/follower registration and delivery, and hot downgrade back to classic with follower disconnect. The observed downgrade status convergence can take around 10 seconds, which is acceptable for the current retry-based safety model but should remain evidence-gated if it becomes user-visible friction.
Open work:
- Capture text diagnostics if Windows classic restore/status convergence repeatedly exceeds the intended 5–15 second fallback window.
- Add a focused regression or transport/status adjustment only if new Windows evidence shows a repeatable named-pipe, lock, heartbeat, queue, or status-convergence issue.
Done when: new Windows-specific runtime issues are either fixed with targeted coverage or left out of the backlog because the native smoke remains green.
Context: The release should avoid speculative live-test matrices. Deterministic coverage already protects target propagation, native typing/activity scoping, hot Threaded Mode upgrade/downgrade, delivery routing, and core leader/follower behavior. Future Telegram-client quirks should be handled only when there is concrete evidence or a minimized fixture.
Open work:
- Capture any new Telegram client or Bot API behavior that contradicts the documented Threaded Mode contract.
- Add a focused regression or documented client caveat only for confirmed behavior.
- Keep one-off live environment names, thread names, and operator-specific observations out of repository context unless they demonstrate a general product issue.
Done when: new client quirks are either fixed with targeted coverage or documented as evidence-backed exceptions, without keeping broad manual smoke matrices in the backlog.
Context: Native Rich Markdown is the default assistant delivery path. Existing regressions cover known parser/client edges such as space-after-marker blockquotes, dollar-prefixed ticker atoms, list indentation, code fences, links, display math normalization, and long-message splitting. Further rewrites should be evidence-driven, not speculative.
Open work:
- Capture any new Telegram parser-breaking sequence from live/client evidence or a minimized fixture.
- Add a conservative normalization or safe-degradation rule only for confirmed sequences.
- Keep unconfirmed speculative rewrites out of the delivery path.
Done when: newly observed Rich Markdown failures have minimized fixtures and targeted regressions, while stable rendering behavior remains unchanged for unsupported guesses.
Blocked: upstream Pi core API. Issue: earendil-works/pi#5952
Context: Threaded Mode manual followers are separate visible Pi processes. Same-thread /new is a different feature: replacing the current Pi session inside the same Telegram thread. Extension-only hacks are rejected because they would desynchronize Pi lifecycle/TUI semantics.
Required upstream shape:
pi.newSession(...)orpi.requestSessionReplacement(...)callable from trusted extension runtime code.- Must use the same session-replacement path as the terminal command, including normal
session_shutdown/session_startlifecycle.
Constraints:
- Do not store stale
ExtensionCommandContext. - Do not inject TUI input.
- Do not spawn a shadow
pisubprocess. - Do not mutate session files directly.
- Do not route through
pi.exec; it is shell execution, not a Pi slash-command dispatcher.
Done when: /new in the current Telegram thread performs an official same-instance session replacement, preserves the thread binding, rebinds after lifecycle restart, reports success/cancellation in the same thread, and has regressions for active turns, pending Pi messages, queue state, preview cleanup, cancellation, failure, and success.
