917a229363 feat: Domain 2 Phase 3-4 — wiki article tool, DCP compress toggle, Go sidecar deprecation
Phase 3: get_wiki_article tool wraps codesight_get_wiki_article MCP
(cached, persistent codebase wiki). DCP compress toggle on
get_codebase_overview (compress=true for large projects >50 files).

Phase 4: Deprecation markers on Go codecontext sidecar. Warning log
in callCodecontext(), deprecation comments in factory.ts and
docker-compose.yml. Sidecar remains functional — removal deferred.

203cfd2fa8 feat: DeepSeek API integration + Whale lift (hooks, tool repair, MCP permissions, token tracking)
DeepSeek API:
- @ai-sdk/deepseek provider replaces openai-compatible for deepseek-* models
- Token tracking: cache_hit/reasoning tokens flow API → DB → WS frames → UI
- thinking effort levels (off/low/medium/high/xhigh/max) via AGENTS.md frontmatter
- V4 models: deepseek-v4-flash, deepseek-v4-pro
- Wired for both chat and coder panes

Whale lifts:
- Tool input repair (schema-based type coercion, markdown link unwrapping)
- Hooks system (6 lifecycle events, shell exec, JSON stdin/stdout contract)
- Per-MCP-server permissions (allow/ask/deny)
- token tracking UI (cache N, think N in message stats line)

Infra:
- New DB columns: messages.cache_tokens, messages.reasoning_tokens
- New WS frame fields: cache_tokens, reasoning_tokens on message_complete
- coder provider snapshot merges DeepSeek models alongside llama-swap

c11e26090f feat(coder): boulder state — cross-session plan persistence + auto-resumption
New plans table (id, project_id, title, description, status, flow_run_id,
progress_pct, items_total, items_completed, metadata, timestamps) with
CHECK constraints and indexes.

Plan store (plan-store.ts): createPlan, getPlan, listPlans, listActivePlans,
updatePlan, updatePlanFromRun, findPlanWithRunningRun, planStatusFromRun.

Flow-runner integration: onRunTerminal callback fires on every terminal
transition (complete/fail/cancel) and updates linked plans automatically.

5 API endpoints: GET /api/plans, GET /api/plans/active, GET /api/plans/:id,
POST /api/plans, PATCH /api/plans/:id.

484 tests pass, build clean.

3c5b2c2bcf feat(server): Domain 2 Phase 1 — boocontext MCP client + 4 new code intelligence tools
Shared boocontext MCP client (boocontext_client.ts) wrapping the existing
mcp-client.ts callTool() infrastructure with 32KB truncation and error
handling. Used by get_code_health.

4 new first-class agent tools backed by the boocontext MCP server:
- get_code_health — A-F grades per file across 7 dimensions, project health
  summary, refactoring candidates (wraps boocontext_health)
- get_code_impact — merged symbol trace + blast radius in one call (wraps
  boocontext_impact, replaces two-step get_symbol_info+get_blast_radius)
- get_type_info — TypeScript type recovery via type-inject MCP (wraps
  boocontext_types, returns signatures, interfaces, generics, JSDoc)
- get_code_map — DCP-compressed context map with compress toggle (wraps
  boocontext_map, 10x token reduction vs full scan)

All 4 registered in ALL_TOOLS as read-only tools.

a7a40c5b46 feat(coder): add hashline editing core + wire audit hooks into dispatch pipeline
Hashline editing: content-hash anchors for edit_file stale-patch detection.
Pure-JS xxHash32, line hash computation, validation with HashlineMismatchError,
256-entry hash dictionary. 6 files in apps/coder/src/services/hashline/.

Audit hooks: emitHook('tool.execute.after') wired in frame-emitter.ts for
completed/failed tool results. emitHook('turn.end') wired at terminal points
in dispatcher.ts (all 5 run functions: native, external, opencode, warm ACP,
claude SDK). Fire-and-forget, non-blocking.

usage and tokens/sec. Removing them from the shadowing lists allows agents
to enable them via llama_extra_args.

creation/end/recover/report-daily with JSONL buffer and graded context
recovery (L0-L4). Guideline service for behavioral compliance rules
(condition/action model with criticality). Correction service for
persistent user correction tracking across agent sessions.

8 supporting skills: audit-start/end/report-daily/recover + command
variants for slash-command integration.

cce685b1a7 fix(coder): harden edit-apply pipeline against block duplication
Root cause: two proven corruption mechanisms — (M1) non-idempotent apply
stamped the same block N times when a quantized model re-emitted the same
edit_file call or a turn was retried; (M2) Levenshtein tier 4 was fail-open
with no uniqueness guard, silently splicing into the wrong location.

Fixes applied at every layer of the pipeline:

Matcher (fuzzy-match.ts): raise SIMILARITY_THRESHOLD 0.66 → 0.85; add
AMBIGUITY_EPSILON uniqueness guard — two windows within 0.05 of the top
score → ambiguous, not a guess; add block-anchor gate (≥3-line needles
require first+last line exact match before a window is scored).

Edit planner (pending_changes.ts): extract planEdit() as a pure function;
idempotency guards detect already-applied states (anchored insert re-stamp,
old-gone-but-new-present); findPendingDuplicate() collapses identical
pending rows at queue time so M1 never reaches applyOne.

Atomic writes (pending_changes.ts): temp-file + rename on the same
filesystem so a crash can't leave a half-written source file; realpath()
first so symlinks survive the rename.

Per-file mutex (pending_changes.ts): withFileLock() serializes concurrent
read-modify-write on the same path via a chained-Promise Map.

EOL preservation (pending_changes.ts): normalize CRLF → LF for matching,
restore native line ending on write so Windows-style files stay clean.

Context isolation (inference_context.ts): replace module-level singleton
with AsyncLocalStorage so concurrent inference runs (arena parallel
dispatch, dispatcher poll racing a user message) each get their own
scoped context with no clobbering.

Tests: plan-edit.test.ts (pure planEdit unit tests), extended fuzzy-match
and pending_changes_integration suites, ALS isolation test that proves
overlapping runs get correct session IDs.

d6d246c15b feat(web,coder): arena pane — compare 2-6 AI competitors on same prompt
Arena is a new pane kind for competitive AI evaluation. A Battle runs
the same prompt against 2-6 Contestants across two concurrent lanes:
local lane (llama-swap models, serial) and cloud lane (parallel).

Added to all three registries: @boocode/contracts WsFrameSchema,
server InferenceFrame, and web WsFrame.

Backend (apps/coder):
- arena-runner: battle scheduler, lane classifier, benchmark, results
  writer, resume, user winner override
- arena-analyzer: two-stage digest→judge analysis on DEFAULT_MODEL
- arena-decisions: status transitions and resume logic (unit-tested)
- arena-analyzer-helpers: pure helper functions (unit-tested)
- arena-model-call: model call utility for analysis
- arena routes: create/get/list/stop/analyze/cross-examine/winner/diff
- schema: battles, contestants, cross_examinations tables (idempotent)
- remove old /api/arena* routes and tasks.arena_id column

Frontend (apps/web):
- ArenaLauncherDialog: battle type, prompt, contestant selection
- ArenaPane: live roster, streaming output, analysis, cross-exam
- DiffView: unified diff with line-by-line color for coding contests
- Winner override per-row dropdown (Trophy icon)
- battle_updated WS handler for live winner/analysis updates
- arena pane kind in Workspace, ChatTabBar, useSidebar

Cross-app:
- ArenaState and ArenaContestantShape/WsFrame types (contracts)
- battle_* frames in WsFrameSchema, InferenceFrame, and web WsFrame
- manifest.json written per battle results folder
- /Arena added to .gitignore

e04d0fdaa8 feat(coder): unified Plan/Ask/Bypass permission picker
Replace the raw per-agent mode dropdown in the BooCoder composer with a
curated three-option permission ladder mapped generically onto each
provider's native modes: `plan` id -> Plan, default -> Ask, isUnattended
-> Bypass (claude bypassPermissions, qwen yolo, opencode full-access).
modeId stays the single wire field; the active unified mode is derived
from it (no contracts change).

Native BooCode gains its own mode set: Ask stages to the pending-changes
queue (today's behavior), Bypass auto-applies the queue to disk after the
turn (interactive messages path + task dispatcher path), Plan falls back
to Ask. The shared apps/server inference engine is left untouched.

Also preserve isUnattended on live-probed ACP modes so opencode's bypass
mode stays detectable from the wire.

Coder 373 tests green; coder + web typecheck clean.

875cae0843 fix(coder): parse YAML block-scalar descriptions in slash command discovery
Most plugin/han SKILL.md and command files write `description:` as a folded
block scalar (`>` / `|`) with the text on the following indented lines. The
old single-line frontmatter reader captured the literal `>`, so the slash
menu showed garbage/blank descriptions for nearly all of them. frontmatterField
now collapses folded blocks (join with spaces) and preserves literal blocks.

Each flow row in the launcher and each command in the / slash picker now

what/when blurb (condensed from the Han skill descriptions). Launcher gets a
read-only pill and a per-row Run separate from expand; the fast/concise
toggle is now wired through to the conductor workers. Shared ChatInput, so
the slash explanations cover both BooChat and BooCoder. Web tsc clean.

1937af8df9 feat: in-app Orchestrator (Phase 2) — multi-agent conductor
Brings the deterministic Han-flow conductor into BooCode: launch any read-only
flow from BooChat or BooCoder, watch each agent stream live in a Paseo-style
run pane, get an evidence-disciplined report — on local Qwen, persisted and
resumable. Read-only enforced hard via qwen --approval-mode plan (orchestrator
tasks fail closed if qwen is unavailable; never fall to write-capable native).

Backend (apps/coder): re-homed conductor defs, flow_runs/flow_steps schema,
flow-runner + dispatcher onTaskTerminal hook, restart-resume, runs routes
(launch/list/get/cancel), user-channel WS. Contracts: two flow_run_* frames.
Web: orchestrator pane kind + OrchestratorPane, Workflow button + slash flows
(BooChat/BooCoder parity), FlowLauncherDialog, "New Orchestrator" in the + and
split menus, runs history + export. Plan: openspec/changes/orchestrator.

Add a warm orange glow (static rim + drop, gentle gated idle pulse) on the
primary action for BooCode Classic, matching Override's treatment but
calmer (no glitch). Also fix the context-meter ring on both warm themes:
its `stroke-muted` track ≈ the background, so only the fill showed — give
the track a faint warm stroke so the full ring reads.

f5e71bf989 fix(themes): show the rain/neon field behind the app background
The AppShell root carries `bg-background`; on a full-viewport element that
~86%-opaque panel token painted a sheet over the z-0 canvas, hiding the
matrix rain (Classic) and neon field (Override) behind it while pseudo-
element effects like the scanline still showed. Make the root transparent
for both canvas themes so the field shows through; the opaque html backstop
stays the base and panels keep their own translucent backgrounds.

d8bb2dabfe feat: git diff panel (Files/Git tab in the file browser)
Adds a Git tab to the right-side file panel that shows the project
repository's diff and lets the user stage, unstage, commit, and discard
whole files in-session. Two comparison modes (Uncommitted vs HEAD, and the
branch vs its base — upstream tracking branch else default branch), auto-
selected by repo state on first open and pinned after explicit choice;
per-file expand/collapse with lazy syntax-highlighted diffs, +/- stats, and
binary/large-file placeholders. All git read and write logic lives in
apps/server via a new git_diff service: argv-safe execFile only (never a
shell), per-file paths validated repo-relative through pathGuard with a
realpath symlink-escape check, server-derived commit identity (the request
carries no author fields), and the write endpoints are deliberately absent
from the assistant tool registry. Reads are bounded (30s deadline, 10MB);
an index lock or an in-progress merge/rebase/cherry-pick/bisect surfaces as
"repository busy" and disables writes. The panel stays current via a client
git_diff_refresh session event (no new wire contract) coalesced across tab
open, mutations, turn completion, and pending-change apply. Discard is an
