Two native-inference hardening features from boocode_code_review_v2 §1 #12.
MistakeTracker: new pure mistake-tracker.ts tracks consecutive heterogeneous
tool failures (kinds surfaced per tool from tool-phase.ts). On 3 in a row the
turn loop soft-nudges (model-facing recovery guidance + mistake_recovery
sentinel + reset), then escalates to stopping the turn (cap-hit-style, Continue
affordance) on a re-trip. Complements doom-loop (identical repeats) + cap-hit.
File-provenance ledger: compaction.ts derives a deterministic ## Files Read list
from the head messages' read-tool calls and injects it into the rolling-summary
prompt so provenance survives compaction (no new table; read-only).
mistake_recovery sentinel: MessageMetadata arm (server + web) + MessageBubble
render branch. Built by 2 parallel agents. Server 545 tests passing (23 new);
build + web tsc clean. Native-inference only. Builds on v2.7.3.

#3 Fuzzy patch applier: new pure fuzzy-match.ts (locateMatch, exact→trim→
unicode-canon→Levenshtein≥0.66, refuse-on-ambiguous) wired into pending_changes
applyOne/rewindOne so local-model whitespace/unicode drift in old_string no
longer loses the edit.
#4 Worktree checkpoint + conversation-trim: checkpoints table + checkpoints.ts
(shadow-commit of tracked+untracked into refs/boocode/checkpoints, hooked into
the 3 external-agent dispatcher paths) + POST restore route (reset --hard +
clean -fd -> transcript trim -> backend-session reset) + "Restore to here" UI.
Built by 3 parallel agents; DB-integration testing caught a created_at
self-deletion bug. Coder suite 234 passing; server+coder build + web tsc clean.
Builds on v2.7.0-mit. openspec write-edit-robustness.

A cohesive batch of pane/tab UX + the persisted workspace-state model (grouped
because the changes interleave across useWorkspacePanes, ChatTabBar, Workspace,
sessionEvents and the api types/client):
- Open a whole chat in a fresh pane via a new open_chat_in_new_pane event:
ChatTabBar tab context menu "Open in new pane", and MessageBubble.fork() now
lands the fork beside the original instead of replacing the active pane.
openChatInNewPane detaches the chat from any pane already holding it
(one-chat-per-pane).
- The tab-bar "+" becomes a New BooChat/BooTerm/BooCode menu (chat as a tab,
term/coder as split panes); the split button is unchanged.
- Drop the per-message "Open in pane" button (it opened a single message's
artifact) and its dead code; the artifact-pane machinery is left orphaned for
a later teardown.
- Session history: the empty/landing pane lists the session's open chats plus
archived chats (fetched separately), click to open / restore-and-open.
- Relocate-on-close: closing a chat pane moves its tabs (in order) into the
oldest chat/empty pane instead of discarding them; terminal/coder panes close
as before. Reopen strips the restored chatIds from all live panes first, so a
relocated-then-reopened pane never duplicates a tab — no stack-shape change.
- Stable global tab numbering: tabNumbers/nextTabNumber assigned on chat-pane
open, retired on close (never reused), rendered map-keyed (not positional).
- workspace_panes is now a WorkspaceState envelope { panes, tabNumbers,
nextTabNumber, closedPaneStack }; the reopen stack moved from a module-level
array into the persisted envelope so it survives reload. Hydrate/persist
normalize the legacy bare-array shape. appendClosed dedupes a value-identical
top entry to neutralize the StrictMode double-invoke of the setPanes updater.

Bundles in-progress working-tree UI work not authored this session (CoderPane ChatInput migration, AgentComposerBar/CoderMessageList/tab-bar/sidebar/pane refinements, provider icons) with this session's changes to the same files: MessageBubble renders a collapsible 'Thinking' block from reasoning_text/reasoning_parts (surfacing ACP agent_thought_chunk + native reasoning), and the DiffPanel approve/reject calls are repointed to the real /api/coder/pending/:id/apply and /reject routes (the old /sessions/:id/pending/:id/approve|reject paths did not exist).

Every assistant message gets an "Open in pane" affordance that opens the
message in the workspace splitter — Markdown pane (Copy + Download .md) by
default; HTML pane (Download .html only) when the model emits a self-contained
<!DOCTYPE html> or fenced ```html artifact. BOOCHAT.md rule keeps Markdown
default at every length; HTML opt-in on explicit user request.
Backend: services/artifacts.ts (slug derivation + write helpers with
symlink-escape guard via realpath-after-mkdir), routes/artifacts.ts (POST
download + GET stream with nosniff + CSP sandbox defense-in-depth), HTML
detection in finalizeCompletion writing a new message_parts.kind='html_artifact'
row (schema CHECK extended via v1.13.13 pattern), graceful 1MB cap via the
pure decideHtmlArtifactWrite helper. PartKind union extended.
Frontend: MarkdownRenderer.tsx extracted from MessageBubble's inline
MarkdownBody for reuse; MarkdownArtifactPane.tsx + HtmlArtifactPane.tsx with
loading/error states; pane state is reference-only ({chat_id, message_id,
title}) — content fetched on mount to keep workspace_panes jsonb small and
avoid 1MB blobs riding session_workspace_updated frames. iframe sandbox
locked to allow-scripts allow-clipboard-write allow-downloads with no
allow-same-origin, srcDoc not src. openInPane discriminates 404 (expected
fallback) from real errors (toast + bail). PanelRightOpen icon button with
mobile 44px tap-target.
31 new server unit tests including a real-symlink filesystem case; 332/332
server tests passing, tsc clean both sides, pnpm -C apps/web build green.
Smoke deferred to first deploy.

Five fixes for latent regressions surfaced during the v1.13.x.cosmetic
revert investigation. None alter schema or compaction; all cleanup
against the v1.13.1-A AI SDK migration's hidden surface.
(1) provider.ts — includeUsage: true on createOpenAICompatible.
@ai-sdk/openai-compatible defaults this false, omitting
stream_options.include_usage from the request body; llama-swap never
emitted the usage block, so result.usage.inputTokens/outputTokens
resolved undefined and tokens_used / ctx_used landed NULL in every
assistant row since v1.13.1-A. No historical backfill.
(2) MessageList.tsx — hasText = m.content.trim().length > 0.
AI SDK v6 streaming occasionally emits a leading "\n" text-delta on
tool-call-only turns; the literal newline passed length > 0 and
rendered an empty bubble + ActionRow between every tool call. Trim
catches it without changing semantics for genuine content.
(3) MessageBubble.tsx — same trim on hasContent for the no-tool-calls
path. Defensive symmetry with MessageList.flatten.
(4) payload.ts — buildMessagesPayload skips assistant rows with
status='failed' AND assistant rows with status='complete' + empty
content + no tool_calls. Without this, a trailing empty/failed
assistant + the next attempt's placeholder produced "Cannot have 2
or more assistant messages at the end of the list" rejections from
the OpenAI-compatible upstream after cap-hit + Continue.
(5) budget.ts — BUDGET_NO_AGENT 15 → 30. Every tool in ALL_TOOLS is
read-only today; the 15-cap was forward-looking for write tools that
haven't landed. No-agent mode now matches BUDGET_READ_ONLY.
47 LoC across 5 files. 190/190 server tests pass.
Verified live: new assistant turns populate StatsLine token data;
single-tool-call turns no longer render the stray empty-bubble +
ActionRow between tool calls; Continue after cap-hit no longer hits
the trailing-assistant API rejection.
Old hardcoded MAX_TOOL_LOOP_DEPTH=15 replaced by per-agent
max_tool_calls (1-100, AGENTS.md frontmatter) with defaults: 30 for
read-only-only agents, 10 for agents that include any non-read-only
tool, 15 for raw chat. When the loop hits cap, fire one final summary
call with tools disabled, stream the wrap-up into the in-flight
assistant message, then insert a system sentinel with
metadata.kind='cap_hit'. The sentinel renders an amber bubble with a
Continue button (latest sentinel only) that POSTs to a new
/api/chats/:id/continue route to extend. Hard ceiling: 3 cap-hits per
chat (2 continues max) — third sentinel reports can_continue=false.
Error frames carry a machine-readable reason code alongside human
error text. Failed messages persist the reason via
metadata.kind='error' so the bubble renders specifics on reload (WS
error frame is one-shot).
Tool call UI rewired: ToolCallLine renders inline (↳ name args
spinner/check/✗, expand-on-tap for args+result); ToolCallGroup
collapses 3+ consecutive same-tool runs into a compact card.
MessageList owns a three-pass pre-render (flatten + fold tool
results onto matching runs by id + group same-tool runs + number
sentinels). MessageBubble drops tool rendering and adds the
sentinel / error-reason branches. ToolCallCard deleted.
Roadmap follow-up logged: add explicit max_tool_calls: 30 to the 6
agents in /data/AGENTS.md and /opt/boocode/AGENTS.md post-ship for
discoverability (defaults handle behavior identically).

- ChatInput: e.nativeEvent.isComposing early-return added (CJK IME
safety — first Enter of a composition no longer submits). Bare-Enter
send path gated by !isMobile so mobile inserts a newline; send is
button-only. Cmd/Ctrl+Enter and Shift+Cmd/Ctrl+Enter retained as
desktop secondary bindings. Placeholder is now viewport-aware. Outer
wrapper gets paddingBottom: env(safe-area-inset-bottom) so iOS home
indicator doesn't overlap.
- MessageBubble: ActionRow buttons (Copy / Regenerate / Fork / Trash)
bumped to max-md min-h/min-w 44px; opacity-100 on mobile so actions
don't hide behind a hover-to-reveal pattern. User bubble and
assistant content wrapper gain break-words + min-w-0 so long
unbreakable strings (URLs / paths) wrap rather than blowing out
the column on narrow viewports.
- ChatPane: queued-message dropdown + close X + Stop-generating button
hit max-md 44px sizing.
- ChatTabBar: per-tab X, +/History/Close-pane action buttons hit
max-md 44px. Tab close X is force-visible on mobile (no
hover-to-reveal).
- M8: CodeBlock / Markdown tables / ToolCallCard already wrap
overflow-x-auto pre-existing — no source change needed there; the
break-words + min-w-0 additions above are the new defensive layer.

- Fork: POST /api/chats/:id/fork creates a new chat in the same session,
copies messages up to target (status=complete) with row-offset
clock_timestamp() for stable ordering. Client emits open_chat_in_active_pane
event; Workspace opens it in the active pane. No maybeAutoNameChat on forks.
- Delete: DELETE /api/chats/:id/messages/:message_id with 409 if the chat is
currently streaming. Cascading-forward delete (created_at >= target).
MessageBubble Trash button + confirm Dialog.
- Header: Projects -> Project -> Session breadcrumb, model badge pill,
inline session rename, active file path via new useActivePane() hook.
Server now publishes session_renamed on PATCH /api/sessions/:id;
client-side dup emit removed from Session.tsx.
- Housekeeping: NOW() -> clock_timestamp() in schema.sql defaults, dead
PaneTab.tsx and panes/PaneShell.tsx removed, session_panes backfill
INSERT removed (CREATE TABLE retained), Tailnet trust comment near
app.listen().

- Fastify global empty-JSON-body parser fixes archive/unarchive/stop 400s
- Removed redundant local sessionEvents.emit at all 5+2 sites with server-side WS publishers; added dedupe guards in useSidebar/Workspace/Project handlers
- Sidebar session right-click adds Delete (destructive) with confirm Dialog
- Session.tsx navigates away on session_deleted/session_archived for the active session
- SessionLandingPage chat rows show message_count, effective_context_tokens, last_message_preview via LATERAL joins on GET /api/sessions/:id/chats
- Workspace.tsx pane drag-to-reorder using native HTML5 events (no new deps)
- CompactCard: Copy toast, Send-to-chat with target chat name, empty-state in share popover, Re-run button
- auto_name.ts: filter count gate and assistant-fetch by content <> '' so tool-call assistant rows don't trip the once-and-only-once guard
- Adds CLAUDE.md and apps/web/src/lib/format.ts

Session 1:N Chat data model with backfill. Workspace switches to client-side
multi-tab pane management. Right-rail file browser with float-over viewer and
click-drag line selection replaces FileBrowserPane. Adds /compact streaming
summarizer (respects compact markers in context builder), force-send (cancels
in-flight, persists partial as 'cancelled', awaits cancellation completion via
deferred Promise + 5s timeout), message queue, stop generation, chat
auto-rename, session archive/unarchive with Closed Sessions section on repo
landing page. CHECK constraints on sessions.status, messages.role,
messages.status with KEEP IN SYNC comments tying to MESSAGE_ROLES /
MESSAGE_STATUSES const arrays. Deletes dead pane routes/hook and the
api.panes.* client block.

cloneElement does not carry el.key through unless explicitly passed.
Without it, react-markdown's inline-element siblings (strong/em/text)
lose their reconciler keys on every render, causing potential diffing
churn. Pass el.key (with fallback) explicitly.

- MessageBubble & ToolCallCard: detect path-like strings in rendered text
via regex requiring slash+extension; clicks dispatch open_file_in_browser
- Session.tsx: now renders <Workspace sessionId projectId>; on mount,
emits session_loaded so sidebar can highlight even deep-linked sessions
not in the recent_sessions cache
- ProjectSidebar: active project's chevron visually disabled (50% opacity,
cursor-not-allowed) and click no-op; activeSession from useSidebar used
as fallback when active session isn't in cache

Four features land together on this branch:
1. Markdown rendering — assistant messages go through react-markdown +
remark-gfm. Fenced code blocks render via existing CodeBlock (with copy
button); inline `code` is styled inline. User messages stay plain text.
No raw HTML (no rehype-raw).
2. Per-message Copy + Regenerate. New endpoint
POST /api/sessions/:id/messages/:message_id/regenerate validates the
target (404/400/409), atomically deletes the target plus any later
messages in the session, inserts a fresh streaming assistant row, and
enqueues a normal inference run. The DELETE bound uses a SQL subquery
(`created_at >= (SELECT created_at FROM messages WHERE id = $1)`)
instead of a JS round-trip so postgres TIMESTAMPTZ µs precision is
preserved — otherwise sub-ms clock_timestamp() differences between the
user row and the assistant row collapsed to the same JS Date, pulling
the triggering user message into the >= bound. New `messages_deleted`
WS frame so already-connected clients prune the stale tail without
needing a full snapshot resend.
3. tok/s + ctx counter. Five new nullable message columns: tokens_used,
ctx_used, ctx_max, started_at, finished_at. started_at is set right
before the OpenAI call in services/inference.ts (not in the route, not
in the frame handler); finished_at + tokens_used + ctx_used + ctx_max
are committed in the same UPDATE that flips status to 'complete'. The
inference request now opts into stream_options.include_usage so the
final chunk carries usage; defensive parsing also picks up timings.n_ctx
when llama.cpp emits it (currently absent for our llama-swap models, so
ctx_max stays NULL and the UI just shows `<used> ctx`). message_complete
frame extended with tokens_used / ctx_used / ctx_max / started_at /
finished_at / model. Frontend StatsLine in MessageBubble computes tok/s
client-side from the timestamps and renders muted mono text below the
body of completed assistant messages.
4. AI chat naming after the first turn. Backend services/auto_name.ts
runs via setImmediate after the top-level inference resolves; it
checks that there is exactly one completed assistant message and that
the session has not been user-renamed (`name IS NULL OR name = '' OR
name = 'New session'`), then fires a single non-streaming chat
completion with the spec prompt. Qwen3 chat templates emit chain-of-
thought into reasoning_content and burn the entire max_tokens budget
without producing visible output, so the request includes
`chat_template_kwargs: { enable_thinking: false }` and max_tokens=30.
Title is trimmed, quote-stripped, "Title:" prefix dropped, and
truncated to 60 chars before a guarded UPDATE on sessions.name. New
`session_renamed` WS frame propagates to the open session view
directly and to the project's session list via a tiny module-scope
event bus (apps/web/src/hooks/sessionEvents.ts) — kept dumb: one event
type, two methods, no library.
Cleanups: dropped the now-unused splitCodeBlocks export from CodeBlock.tsx
(react-markdown supersedes it), and added a long-form NOTE in auto_name.ts
documenting the enable_thinking + max_tokens pattern for any future Qwen-
family non-streaming utility calls (planned: fork-message, agent-routing,
web-search summarization).
Schema bootstrap remains idempotent (ADD COLUMN IF NOT EXISTS). Auth,
broker, clock_timestamp() conventions, and zod validation all unchanged.
