* fix(chat): allow failed turns to be forked
Failed turns can end in Paseo-generated timeline items without provider
message IDs. Anchor forks to canonical timeline positions while retaining
legacy boundaries for compatibility.
Place the fork summary before the new prompt and delimit it as structured
chat history.
* fix(chat): tighten fork boundary handling
* fix(chat): keep attachments visible after creating agents
Agent creation could receive the canonical user message before the client knew the new agent ID. Hand the local rich presentation to that message and preserve it through later timeline hydration.
* refactor(chat): clarify local message presentation naming
* fix(chat): clear pending state after message handoff
* fix(app): preserve assistant stream order
Assistant head flushing only considered item kind, so a new identified assistant message could promote ahead of earlier live rows. Flush the live head when assistant message ids diverge so live rows remain an ordered suffix.
* refactor(app): reuse assistant message id helper
* Extract client SDK package
* Polish SDK client identity defaults
* Build client before dependent CI jobs
* Restore daemon client server export
* Extract protocol and client SDK packages
* Fix provider override schema validation
* Fix app test daemon client imports
* Simplify workspace build targets
* Fix CLI test server build bootstrap
* Run SDK package tests in CI
* Fix rebase package split drift
* Restore lockfile registry metadata
* Update SDK config test for prompt default
* Move terminal stream router test to client package
* Fix rebase drift for protocol imports
* Fix SDK agent capability fixture
* Restore legacy server client exports
* Fix server export compatibility test
* Advertise custom mode icon client capability
* Remove server daemon-client exports
* Format rebased mode control import
* Fix rebase drift for protocol imports
Files added by upstream PRs (#893, #1147, #1154) referenced the pre-split
shared/ paths that this branch moves into @getpaseo/protocol. Redirect
those imports to the protocol package so typecheck stays green after the
rebase.
Move optimistic user message reconciliation into the stream reducers and keep draft-created agents in a handoff lifecycle until authoritative history lands.
* Add Pi extension-launch plumbing for in-process tree primitives
* Add Rewind controls for agent sessions
* Preserve SDK checkpoint env var so Claude file rewind works
The SDK injects CLAUDE_CODE_ENABLE_SDK_FILE_CHECKPOINTING=true when file checkpointing is enabled. The earlier parent-env stripping from c4782ec71c was too broad and removed that child flag along with real parent-session markers.
Keep stripping parent markers, but preserve the checkpoint flag so the SDK rewind path can run directly. With that boundary fixed, the JSONL file-rewind fallback is no longer needed.
* Update OpenCode history replay tests for rewind state
* Show Rewind actions in an adaptive sheet
* Fix rewind semantics across providers
* Refactor Pi IDs through extension capture
* Restore user message to composer after rewind
* Fix Claude rewind tool result mapping
* Fix Claude rewind session switch roundtrip
* Fix rewind and optimistic message regressions
* Tighten rewind test discipline
* Fix OpenCode optimistic message reconciliation
* Reconcile optimistic user messages by marker
* Reorder user message actions
* Unify provider user message contract
* Add Claude rewind flow Playwright contract
* Add Codex rewind flow Playwright contract
* Add OpenCode rewind flow Playwright contract
* Add Pi rewind flow Playwright contract
* Remove real-provider rewind Playwright contracts
* Gate real-provider rewind specs from CI Playwright
@fireblue diagnosed the production failure mode: long canonical timeline catch-up could exceed the relay WebSocket frame cap, close with 1009, and send clients into a reconnect loop. Their seatbelt fix also removed the `limit: 0` footgun that let app callers request an unbounded frame.
This maintainer pass keeps that diagnosis and redirects the UX around bounded projected pages:
- initial agent load fetches the latest canonical tail
- app resume/reconnect re-fetches the latest tail instead of chaining after-cursor pages
- in-stream gaps still use bounded after-cursor catch-up
- older history loads explicitly when the user scrolls to the oldest edge
- shared page size is TIMELINE_FETCH_PAGE_SIZE = 100 projected timeline items, matching the daemon's canonical projection semantics rather than raw delta chunks
Original diagnosis and fix by @fireblue.
