- schema.sql: new messages_with_parts view. tool_calls aggregates parts
with kind='tool_call' as a jsonb array of {id, name, args}; tool_results
picks the single sequence=0 part with kind='tool_result' as a jsonb
{tool_call_id, output, truncated, error?}. COALESCE against the legacy
jsonb columns means pre-v1.13.0 history (no parts rows) still reads
correctly via the fallback, and fresh inserts (where parts dual-write
follows the row INSERT) hit the legacy columns until the parts land.
- reasoning_parts column added to the view but not selected by any caller
yet — v1.13.1-C extends the Message type and pulls it into the model
payload alongside the type extension.
- Read sites switched to FROM messages_with_parts:
- routes/chats.ts:427 (chat history GET)
- routes/messages.ts:95 (session history GET)
- routes/ws.ts:27 (WS snapshot on session connect, resume path)
- services/inference/payload.ts (loadContext for model assembly)
- services/compaction.ts (compaction's payload assembly)
- chats.ts:394 (discard_stale UPDATE RETURNING) unchanged — UPDATEs target
messages directly and the returned shape is for a freshly-modified row
where the legacy column is dual-written and correct.
- messages.ts:478/549 (ask_user_input correlation) intentionally not
migrated — those query a different shape, ported in v1.13.1-C.
- Writes still target `messages` directly; the view is read-only.
Smoke verified against the live container:
- Equivalence: 5/5 messages with both legacy column and parts row return
identical tool_calls jsonb between FROM messages and FROM messages_with_parts.
- Perf: EXPLAIN ANALYZE on the 42-message stress chat returns in ~1ms
(50ms threshold). Bitmap Index Scan on message_parts_msg_seq_idx
carries the parts lookups.
- API contract: GET /api/chats/:id/messages returns identical
{id, name, args} tool_calls and {tool_call_id, output, truncated, error}
tool_results shapes to frontend consumers — no UI changes needed.
- Inference path: sent a view_file prompt; assistant turn 1 emitted the
tool_call, tool message captured the result, follow-up assistant turn
read the result back via loadContext (now view-backed) and answered
correctly. End-to-end loop intact.
v1.13.2 drops the dual-write + the JSON columns + simplifies the view
to just SELECT FROM message_parts.

Adds a granular message_parts table (one row per text/tool_call/tool_result
chunk) without changing any read path. Old messages.content / tool_calls /
tool_results columns remain authoritative for v1.13.0; this dispatch is
write-only mirroring so the AI SDK migration in v1.13.1 can flip read
authority without a backfill window.
Schema:
CREATE TABLE message_parts (id, message_id FK ON DELETE CASCADE,
sequence int, kind text CHECK (text|tool_call|tool_result|reasoning|step_start),
payload jsonb, created_at, UNIQUE (message_id, sequence))
New module services/inference/parts.ts with two pure derive helpers
(partsFromAssistantMessage, partsFromToolMessage) and insertParts that
fan-outs a multi-row INSERT via postgres-js.
Wired dual-write at every site that writes tool_calls or tool_results:
- tool-phase.ts: assistant finalize UPDATE, executed-tool UPDATE,
ask_user_input sentinel UPDATE
- messages.ts answer flow: DELETE pending tool_result part + INSERT
answered one inside the existing sql.begin
- skills.ts: synthetic assistant + tool INSERTs both inside existing tx
- chats.ts fork: CTE clones parts via ROW_NUMBER pairing (source→dest
message id mapping in one statement, no N+1)
- error-handler.ts finalizeCompletion: text part for plain text-only
assistant turns
Deviation: tool-phase.ts finalize UPDATEs and finalizeCompletion text-part
write are not wrapped in fresh sql.begin transactions. Safe in v1.13.0
because JSON columns are authoritative for reads. v1.13.1 must wrap these
sites before flipping read authority — TODO comments added at each
unwrapped site referencing v1.13.1.
Tests: 8 new unit tests for the derive helpers in
services/__tests__/parts.test.ts. Existing 162 tests untouched. 170 total.

When an assistant message sits status='streaming' with no token activity
for 60+ seconds, the chat shows a banner above the input offering Retry
or Discard. Both clear the stale row via a new backend endpoint
POST /api/chats/:id/discard_stale that updates status='failed' and
publishes chat_status='idle'.
Closes the UX gap that caused the 2026-05-21 debugging spiral —
slow streams and dead streams now look different to the user.

ContextBar relocated from a dedicated row above MessageList to inline with
the agent-picker row, filling the space to the right of the picker + plus
button. Always-visible (zero-state when no assistant message has run yet)
via chat.model_context_limit, which GET /api/sessions/:id/chats now
populates from a single getModelContext lookup per session.
ChatContextPopover above the input is removed entirely along with its
useChatContextStats hook (no remaining callers). Color tiers and the
auto-compaction threshold tooltip unchanged.

Adds a singleton, ephemeral 'settings' pane kind to the workspace.
Opened via a new bottom-pinned button in ProjectSidebar (emits an
open_settings_pane event when a session is mounted; navigates to
/settings otherwise). Pane has three sections — Session, Project,
Theme — and a maximize toggle that hides sibling pane columns via
display:none on desktop only. Settings panes don't count toward
MAX_PANES and are filtered out of the localStorage persistence layer
so reload always restores a clean workspace.
Schema (additive):
- projects.default_system_prompt TEXT NOT NULL DEFAULT ''
- projects.default_web_search_enabled BOOLEAN NOT NULL DEFAULT false
- sessions.web_search_enabled BOOLEAN (nullable; null = inherit)
Inference resolves user_prompt = session.system_prompt.trim() ||
project.default_system_prompt.trim() — empty/whitespace at either
layer means "no override". Keeps the columns NOT NULL and matches
the existing inherit semantics.
Server routes:
- GET /api/projects/:id (new; settings pane refetches on
project_updated)
- PATCH /api/projects/:id accepts default_system_prompt,
default_web_search_enabled
- PATCH /api/sessions/:id accepts web_search_enabled (tri-state)
- POST /api/projects/:id/sessions/archive-all + GET
/api/projects/:id/sessions/open-count
- POST /api/sessions/:id/chats/archive-all + GET
/api/sessions/:id/chats/open-count
- PATCH /api/sessions/:id now broadcasts session_updated on every
successful PATCH (was rename-only). Lets SettingsPane open in
another tab pick up edits without a refetch.
Bulk-archive publishes one session_archived / chat_archived frame
per affected id so useSidebar's existing reducer cases handle them
incrementally — no new frame type, no payload widening.
ModelPicker refactored: shared ModelList inside a responsive shell.
Desktop = labeled trigger + DropdownMenu, mobile = icon-only Cpu
button + BottomSheet. Header in Session.tsx drops the pill wrap on
mobile since the new trigger is the visual.
ChatInput gains an icon-only '+' DropdownMenu next to AgentPicker
when sessionId + webSearchEnabled props are provided. One item for
now — Web search — with a checkmark reflecting the stored value
(true), not the effective one. Click PATCHes the override; to
restore inherit-from-project the user opens SettingsPane.
ThemePicker lifted out of pages/Settings.tsx into a reusable
component. The standalone /settings route is now a thin wrapper
that mounts <ThemePicker /> with a Back button on top
(navigate(-1) with fallback to '/'); the SettingsPane Theme tab
renders the same picker bare.
Project section delete-flow removed (button + confirm dialog +
handler). Replaced with "Archive all sessions" using the same
two-step count → confirm → fire pattern as "Archive all chats" in
the Session section. api.projects.remove() stays in the client
because useProjects.ts still uses it.
Hand-rolled Switch primitive in SettingsPane (no shadcn switch in
the project; spec said no new deps). Section nav is plain buttons
(no shadcn Tabs).

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).

- 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().

Feature 1 — Tab close menu (pure local pane state, no API):
- ChatTabBar context menu: Rename / sep / Close / Close others / Close to right / Close all
- Workspace bulk-tab primitives: closeOtherTabs, closeTabsToRight, closeAllTabs (manipulate panes[].chatIds, no fetch)
- Drop in-bar Delete; landing card's name-typed Delete is the canonical destructive path
Feature 2 — Chat archive + delete:
- chats.status vocabulary aligned with projects ('open' | 'archived'); DROP old inline CHECK, UPDATE 'closed' → 'archived', ADD new named chats_status_chk
- POST /api/chats/:id/archive (204) + POST /api/chats/:id/unarchive (200) + GET /api/sessions/:id/chats?status=archived; DELETE publishes chat_deleted; PATCH simplified to name-only
- 3 new WS frames: chat_archived, chat_unarchived, chat_deleted (renamed from chat_closed)
- Same dedup discipline: server-only publish, no local sessionEvents.emit in client
- SessionLandingPage: right-click ContextMenu (Open / Rename / Archive / sep / Delete-destructive), inline rename, archive confirm dialog, delete dialog with name-typed Input gated until typed text === chat.name, Archived chats collapsible section with Restore
- Card-level Archive + Delete icon buttons reusing the same dialog state setters; stopPropagation on both so card click still opens the chat; archived cards keep only Restore
UX — chat content width cap:
- ChatPane content (MessageList, queue chips, stop button, ChatInput) wrapped in inner max-w-[1000px] mx-auto w-full so messages center; outer border-t / scroll containers stay full-width so pane chrome and backgrounds remain edge-to-edge
- No new deps, no media queries (narrow viewports collapse to width naturally)

- 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.
