+# Refactor 260: Upgrade libsqlite3-sys
+
+## Description
+
+Upgrade the `libsqlite3-sys` dependency from `0.35.0` to `0.37.0`. The crate is used with `features = ["bundled"]` for static builds.
+
+## Version Notes
+
+- Current: `libsqlite3-sys 0.35.0` (pinned transitively by `matrix-sdk 0.16.0` → `matrix-sdk-sqlite` → `rusqlite 0.37.x`)
+- Target: `libsqlite3-sys 0.37.0`
+- Latest upstream rusqlite: `0.39.0`
+- **Blocker**: `matrix-sdk 0.16.0` pins `rusqlite 0.37.x` which pins `libsqlite3-sys 0.35.0`. A clean upgrade requires either waiting for matrix-sdk to bump their rusqlite dep, or upgrading matrix-sdk itself.
+- **Reverted 2026-03-17**: A previous coder vendored the entire rusqlite crate with a fake `0.37.99` version and patched its libsqlite3-sys dep. This was too hacky — reverted to clean `0.35.0`.
+
+## Acceptance Criteria
+
+- [ ] `libsqlite3-sys` is upgraded to `0.37.0` via a clean dependency path (no vendored forks)
+- [ ] `cargo build` succeeds
+- [ ] All tests pass
+- [ ] No `[patch.crates-io]` hacks or vendored crates

+## User Story
+
+As a user chatting with the Matrix bot, I want it to remember and own its prior responses naturally, so that conversations feel like talking to one continuous entity rather than a new instance each message.
+
+## Acceptance Criteria
+
+- [ ] Conversation history is passed as structured API messages (user/assistant turns) rather than a flattened text prefix
+- [ ] Claude recognises its prior responses as its own, maintaining consistent personality across a conversation
+- [ ] Per-room history survives server restarts (persisted to disk or database)
+- [ ] Rolling window trimming still applies to keep context bounded
+- [ ] Multi-user rooms still attribute messages to the correct sender

+# Story 265: Spikes skip merge and stop for human review
+
+## User Story
+
+As a user, I want spike work items to stop after QA instead of auto-advancing to the merge stage, so that I can review the spike's findings and prototype code in the worktree before deciding what to do with them.
+
+## Context
+
+Spikes are investigative — their value is the findings and any prototype code, not a merge to master. The user needs to:
+- Read the spike document with findings
+- Review prototype code in the worktree
+- Optionally build and run the prototype to validate the approach
+- Then manually decide: archive the spike and create follow-up stories, or reject and re-investigate
+
+Currently all work items follow the same pipeline: coder → QA → merge → done. Spikes should diverge after QA and wait for human review instead of auto-advancing to merge.
+
+## Acceptance Criteria
+
+- [ ] Items with `_spike_` in the filename skip the merge stage after QA passes
+- [ ] After QA, spike items remain accessible for human review (worktree preserved, not cleaned up)
+- [ ] Spikes do not auto-advance to `4_merge/` — they stay in `3_qa/` or move to a review-hold state
+- [ ] The human can manually archive the spike when done reviewing
+- [ ] Non-spike items (stories, bugs, refactors) continue through the full pipeline as before
+
+## Out of Scope
+
+- New UI for spike review (manual file inspection is fine)
+- Changes to the spike creation flow

+## Investigation Notes (2026-03-17)
 
-**Use `git bisect` to find the commit that broke this.** Story 145 delivered working localStorage persistence — something after that regressed it. Find the breaking commit, understand the root cause, and fix it there. Do NOT layer on a new implementation. Revert or surgically fix the regression.
+### Root cause analysis
+
+The frontend correctly:
+1. Persists messages to localStorage in `useChatHistory.ts` (key: `storykit-chat-history:{projectPath}`)
+2. Loads them on mount
+3. Sends the FULL history array to the backend via `wsRef.current?.sendChat(newHistory, config)` in `Chat.tsx` line ~558
+
+The backend bug is in `server/src/llm/chat.rs`:
+- The `chat()` function receives the full `messages: Vec<Message>` from the client
+- Line ~283: `let mut current_history = messages.clone()` — correctly clones full history
+- Lines ~299-318: Adds 2 system prompts at position 0 and 1
+- Lines ~323-404: Main LLM loop generates new assistant/tool messages
+- **Line ~407: `ChatResult { messages: new_messages }` — BUG: returns ONLY the newly generated turn, not the full `current_history`**
+
+During streaming, the `on_update()` callbacks DO send `current_history[2..]` (full history minus system prompts), which is correct. But there may be a reconciliation issue on the frontend where the final state doesn't include the full history.
+
+### Key files
+- `frontend/src/hooks/useChatHistory.ts` — localStorage persistence
+- `frontend/src/components/Chat.tsx` — sends full history, handles `onUpdate` callbacks
+- `frontend/src/api/client.ts` — WebSocket client
+- `server/src/http/ws.rs` — WebSocket handler, passes messages to chat()
+- `server/src/llm/chat.rs` — **THE BUG** at line ~407, ChatResult returns only new_messages
+
+### What NOT to do
+- Do NOT layer on a new localStorage implementation. The localStorage code works fine.
+- Do NOT add server-side persistence. The "dumb pipe" architecture is correct.
+- The fix should be surgical — ensure the full conversation history round-trips correctly through the backend.

+# Bug 258: Auto-assign not called after merge failure
+
+## Description
+
+When the background merge pipeline fails (e.g. quality gate timeout), `auto_assign_available_work` is never called. The story stays in `4_merge/` with no agent assigned, requiring manual intervention.
+
+### Root cause
+
+In `pool.rs`, `start_merge_agent_work` spawns a tokio task that calls `run_merge_pipeline`. On failure, the task updates the job status to `Failed` but does NOT call `auto_assign_available_work`. The only call to `auto_assign` in the merge pipeline is inside `run_merge_pipeline` on the success path (line ~1251).
+
+The `spawn_pipeline_advance` completion handler does call `auto_assign` after the mergemaster agent exits, but only on the success path (post-merge tests pass → move to done → auto_assign). On failure, it returns early without triggering auto-assign.
+
+There is no periodic sweep — auto-assign is purely reactive (watcher events, agent completions, startup).
+
+### Impact
+
+After a merge failure, the story is permanently stuck in `4_merge/` with no agent. The only way to unstick it is to restart the server or manually trigger a watcher event.
+
+## Acceptance Criteria
+
+- [ ] After a merge pipeline failure, `auto_assign_available_work` is called so the mergemaster can retry
+- [ ] Stories in `4_merge/` do not get permanently stuck after transient merge failures

+
+# Bug 264: Claude Code session ID not persisted across browser refresh
+
+## Description
+
+The Claude Code provider uses a session_id to resume conversations via `--resume <id>`. This session_id is stored in React state (`claudeSessionId`) but is NOT persisted to localStorage. After a browser refresh, the session_id is lost (`null`), so Claude Code cannot resume the prior session.
+
+A fallback exists (`build_claude_code_context_prompt` in `server/src/llm/chat.rs:188`) that injects prior messages as flattened text inside a `<conversation_history>` block, but this loses structure (tool calls, tool results, reasoning) and Claude Code treats it as informational text rather than actual conversation turns. In practice, the LLM does not retain meaningful context after refresh.
+
+This is the root cause behind bug 245 (chat history persistence regression). The localStorage message persistence from story 145 works correctly for the UI, but the LLM context is not properly restored because the session cannot be resumed.
+
+Key files:
+- `frontend/src/components/Chat.tsx:174` — `claudeSessionId` is ephemeral React state
+- `frontend/src/components/Chat.tsx:553` — session_id only sent when non-null
+- `server/src/llm/chat.rs:278` — backend branches on session_id presence
+- `server/src/llm/providers/claude_code.rs:44` — `--resume` flag passed to Claude CLI
+
+## How to Reproduce
+
+1. Open the Story Kit web UI and select claude-code-pty as the model
+2. Have a multi-turn conversation with the agent
+3. Refresh the browser (F5 or Cmd+R)
+4. Send a new message referencing the prior conversation
+5. The LLM has no knowledge of the prior conversation
+
+## Actual Result
+
+After refresh, claudeSessionId is null. Claude Code spawns a fresh session without --resume. The fallback text injection is too lossy to provide meaningful context. The LLM behaves as if the conversation never happened.
+
+## Expected Result
+
+After refresh, the Claude Code session is resumed via --resume, giving the LLM full context of the prior conversation including tool calls, reasoning, and all turns.
+
+## Acceptance Criteria
+
+- [ ] claudeSessionId is persisted to localStorage (scoped by project path) and restored on component mount
+- [ ] After browser refresh, the next chat message includes session_id in the ProviderConfig
+- [ ] Claude Code receives --resume with the persisted session_id after refresh
+- [ ] Clearing the session (clear button) also clears the persisted session_id
+- [ ] After server restart with session files intact on disk, conversation resumes correctly
