+# Benchmarks
+
+Published, reproducible CPU benchmarks for graycode-cli. These are TUI-independent
+measurements (no latency theater) run with existing `go test -bench` targets; they
+exist so performance is documented and regressions are visible, not to make
+marketing claims.
+
+## Method
+
+- Runner: `go test -bench=. -benchmem -count=3` on the specific package.
+- Every table reports the median of 3 runs.
+- Repo map benchmark uses a synthetic 100-file Go tree (see
+ `internal/intelligence/repomap/benchmark_test.go`).
+- No benchmark gates releases; this is a reference snapshot.
+
+## Hardware & commit
+
+| Field | Value |
+|---|---|
+| Commit | `b157aaa4` (branch `feat/competitive-analysis-top20`, working tree) |
+| Go | `go1.26.6 linux/amd64` |
+| CPU | AMD EPYC 7543P 32-Core Processor |
+| OS | Linux (cloud amd64) |
+
+## Session save / load
+
+Package: `internal/session` — `BenchmarkSessionSave_*` / `BenchmarkSessionLoad_*`.
+
+| Benchmark | ns/op | B/op | allocs/op |
+|---|---|---|---|
+| Save 100 messages | ~183 µs | 32,488 | 256 |
+| Save 1000 messages | ~790 µs | 255,818 | 2,056 |
+| Load 100 messages | ~2.0 ms | 16,883,848 | 1,067 |
+| Load 1000 messages | ~5.3 ms | 17,721,376 | 10,070 |
+
+Saving is O(n) and cheap; loading allocates heavily (full JSON decode into the
+session graph), which is the expected cost of materializing a full session.
+
+## Repo map generation (size / tokens)
+
+Package: `internal/intelligence/repomap` — `BenchmarkRepoMapGenerate` over a
+synthetic 100-file tree with 2,500 functions/types.
+
+| Metric | Value |
+|---|---|
+| ns/op | ~2.2 ms |
+| est_tokens | 21,600 |
+| format_bytes | 12,451 |
+| B/op | ~364 KB |
+| allocs/op | ~2,425 |
+
+The token estimate is the model-facing budget (`RepoMap.TokenEst`); the format
+bytes are the rendered map text truncated to a 2,000-token budget.
+
+## Reproducing
+
+```bash
+# Session save/load
+go test ./internal/session/ -bench 'BenchmarkSessionSave|BenchmarkSessionLoad' -benchmem -count=3
+
+# Repo map size/tokens
+go test ./internal/intelligence/repomap/ -bench 'BenchmarkRepoMap' -benchmem -count=3
+
+# Everything (slow; runs the whole repo)
+make bench
+```
+
+Record the machine + commit alongside any new numbers before comparing.

+# graycode-cli vs Top 20 OSS — Competitive Analysis
+
+Status: Implemented (branch `feat/competitive-analysis-top20`, 2026-09-09)
+Scope: graycode-cli (this repo) vs 10 AI coding CLIs + 6 dev CLIs + 4 terminals (incl. `herdr` multiplexer)
+Related: `docs/plans/toolbench-comparison-vs-top20.md` (tool-count parity), `docs/SECURITY-DEVELOPER.md` (sandbox model), `docs/plans/pi-adoption-plan.md` (Kitty graphics already proposed), `docs/RESEARCH.md` (top-20 research-paper comparison + implementation record)
+
+## Methodology (no assumptions)
+
+Verified from source in this repo:
+
+- Tools: `cmd/chat_tools.go:41-192` — 34 essential + ~90 lazy-loaded optional (126 unique `tool.*Tool` refs; prior plan counted 69 — surface grew, mostly `spec_*`).
+- Browser/Screenshot: `tool.BrowserTool{}`, `tool.ScreenshotTool{}` in essential set (`cmd/chat_tools.go:75-76`); headless Chrome via chromedp per prior plan.
+- Sandbox: mandatory Docker, fail-closed, never host fallback — `docs/SECURITY-DEVELOPER.md:71-73`, `internal/sandbox/container.go:72-74`.
+- Creds: OS secret store only, no `.env`/env read — `docs/SECURITY-DEVELOPER.md:7-12`.
+- Share: local deeplink only — `internal/session/export.go:801-819` returns `graycode://share/`, no hosted URL.
+- Custom providers: supported — `internal/config/settings.go:50` (`custom_providers`), `internal/config/graycode_router_engine.go:32-50`.
+- Unwired backends: `internal/tool/computer_use.go:67-94` (`SetComputerBackend`, nil default), `internal/tool/media_generation.go:69-71` (`SetMediaEngine`, nil default).
+- Terminal detect covers kitty/ghostty/wezterm/alacritty names (`internal/ui/icons/detect_test.go:56`); Kitty graphics protocol not implemented (see `docs/plans/pi-adoption-plan.md:25`).
+- Bench infra exists (`internal/bench/suite.go`, `internal/feature/eval/`, `make bench`) but README publishes no numbers.
+
+External star counts below are approximate web-search snapshots (2026-09-08), not repo-verified. Treat as order-of-magnitude traction, not exact rankings. graycode-cli is pre-release (`VERSION`: `0.0.1`, `README.md:40-44` source-build primary) — it competes on architecture, not stars.

+| C4 | `wez/wezterm` | ~28k | Rust, MIT | Built-in mux + SSH mux, Lua config |
+
+## Deep dimensions
+
+1. **Traction.** graycode has no star-moat (pre-release). Leaders won via day-1 provider-agnostic + one-liner install + Web/Desktop alongside TUI. graycode already ships script/brew/npm paths (`README.md:48-59`) — keep, don't add Desktop.
+2. **Language/distro.** Go+MIT+zero-CGO (`Makefile:54`, `go.mod:3`) matches `gh/fzf/lazygit` enterprise-safe profile. Avoid GPL/EUPL patterns (kitty/eza). Rust wave wins on published benchmarks — graycode has `make bench` but publishes none (Gap-04).
+3. **Providers.** graycode routes only via `graycode-router/engine` facade (`docs/SECURITY-DEVELOPER.md:51-56`, `ecosystem.yaml:29-30`); custom OpenAI-compat supported (`internal/config/settings.go:50`). Count messaging ("28 first-class" per README) trails OpenCode 75+ / Hermes 300+ — fix by exposing catalog count dynamically, not by forking providers into CLI (ownership lives in router per AGENTS.md).
+4. **TUI/UX.** Bubble Tea v2 + vim keys + `/autonomy` + `/spec` + watch `AI!`/`AI?` + visual diff is competitive. Missing vs field: hosted share-link (ours is local `graycode://` deeplink), multi-session grid (we have `mission` worktrees + daemon — unsurfaced like herdr/cmux). Gap-02.
+5. **Sandbox.** Docker-only fail-closed is strictest default alongside Codex net-off and Gemini gVisor. Tradeoff is onboarding friction without Docker. Must not add host-exec fallback (violates `docs/SECURITY-DEVELOPER.md:71-73`); fix with preflight/path/doctor messaging + image pull/build guidance. Gap-01.
+6. **Memory/context.** AST repomap + Harrier graph + compaction segments + relevance-prune + conversation-arc + 80% tool-result clearing exceeds most. Missing: Hermes-style auto-skill learning loop (we have curator archive + harness — surface it).
+7. **Multi-agent.** `mission` worktrees + family messenger + path reservations + budgets + portable `mission-graph.json` + `graph export` (hashes only) is unique verifiable-execution story. Surface it; no new runtime needed.
+8. **MCP/skills/plugins.** MCP stdio/HTTP/SSE/WS + LSP + skills search/install/audit + curator matches Goose/Gemini/Codex. Contracts live in `internal/contracts` (no `shared/types`) — extensions vendor DTOs. Correct; don't regress.
+9. **Media/computer-use.** Tools exist (`Browser/Screenshot/CodeMatch/SearchX/AppVerify/GenerateMedia/ComputerUse`) but media/computer/STT backends are nil-by-default seams. README notes router ships `ImageClient`/`AudioClient`; host wiring is the gap. Gap-05. Kitty graphics (image display) still missing despite terminal detection. Gap-03.
+10. **Ops/determinism.** Daemon `:4590` health/ready/chat-SSE + cron + `exec --fanout N` + replay cache + circuit breaker + smart routing + harness eval is ahead of Pi minimalism and Aider single-agent. Keep; add published eval numbers (Gap-04).
+
+## Verdict
+
+- **Wins to keep:** fail-closed Docker + dual `/autonomy`+`/spec` gates; portable execution graph; Go zero-CGO MIT; router-facade-only provider access; 120+ tool surface (see `docs/plans/toolbench-comparison-vs-top20.md` for category parity).
+- **Loses to fix (filed as plans):** Gap-01 onboarding friction; Gap-02 share/multi-session; Gap-03 Kitty graphics; Gap-04 published benchmarks; Gap-05 default backend wiring.
+
+## Gap plans (this branch — implemented 2026-09-09)
+
+- `docs/plans/competitive-gap-01-docker-onboarding.md` ✅
+- `docs/plans/competitive-gap-02-share-multisession.md` ✅
+- `docs/plans/competitive-gap-03-kitty-graphics.md` ✅
+- `docs/plans/competitive-gap-04-published-benchmarks.md` ✅
+- `docs/plans/competitive-gap-05-backend-wiring.md` ✅
+
+Each follows the adoption-plan format (Status/Source/Existing/Decision/Priority) and respects developer-first + router-ownership + fail-closed constraints. See `docs/RESEARCH.md` for the research-paper comparison and the extra fixes surfaced by enabling the build.
+
+## Verification
+
+- Source cites above re-checked 2026-09-08 on branch `feat/competitive-analysis-top20`.
+- External stars: web-search snapshots, approximate — re-verify via GitHub API/badges before publishing.
+- Docs-only change: run markdownlint + `make vet` (fast); full `make ci` before PR per `CONTRIBUTING.md:13-17`.

+# GrayCode Ecosystem Roadmap (2026)
+
+**Status:** Active · **Last updated:** 2026-09-09
+**Scope:** the 4 in-workspace repos — `graycode-cli`, `graycode-router`,
+`graycode-skills`, `graycode-platform` — plus the 5 external engine repos they
+depend on.
+**Evidence base:** `docs/RESEARCH.md`, `docs/COMPETITIVE.md`, `docs/plans/competitive-gap-*.md`
+(top-20 OSS + top-20 arXiv papers, 2026-09-09), source audits of all 4 repos,
+and web research (2026-09-09). This document supersedes the stale
+`IMPLEMENTATION-ROADMAP.md` (which still references the retired `starling` /
+`hawk` / `eyrie` names and a 2026-07-05 baseline).
+
+> **Execution status: Phases 0–5 DONE (2026-09-09).** Phase 0 (integrity),
+> Phase 1 (restore the 5 engines), Phase 2 (product honesty + verification
+> surface), Phase 3 (cloud reachability), Phase 4 (skill loop + schema
+> hardening), and Phase 5 (scale-out) are implemented and verified — all Go
+> repos build and test green, skills 382/382, platform 320/320. See the phase
+> sections for per-item completion.
+
+---
+
+## 1. Why this roadmap exists
+
+GrayCode is a terminal-first AI coding agent. It differentiates on four
+load-bearing bets:
+
+1. **Fail-closed Docker sandbox** — agent commands never touch the host.
+2. **Dual `/autonomy` + `/spec` gates** — the agent must plan and justify before acting.
+3. **Portable execution graph** — every agent run is exported as a verifiable,
+ hash-addressed graph (provenance for replay/audit).
+4. **Router-facade-only provider access** — the CLI never talks to an LLM API
+ directly; `graycode-router/engine` is the sole boundary.
+
+The roadmap is organized around making those bets *true and honest* end-to-end,
+then extending the surface where the field (Codex, OpenCode, Gemini CLI, Goose,
+Claude Code) has proven demand.
+
+### The single most important fact (historical)
+
+`graycode-cli` imports **5 engine modules** — `harrier` (memory graph),
+`shrike` (token/compress), `kestrel` (code review), `merlin` (site audit),
+`swift` (session correlation) — that were **absent from this workspace and 404
+on GitHub**. They were replaced in `go.mod` by no-op stubs, so the CLI compiled
+and reported these engines "ready" while every operation silently did nothing.
+
+**This is now fixed (Phase 1, 2026-09-09):** all 5 engines are restored as real
+implementations in this workspace (`../harrier`, `../shrike`, `../kestrel`,
+`../merlin`, `../swift`) and the CLI suite is fully green. The remaining step is
+publishing the engines upstream so the `go.mod` `replace` directives can be
+dropped.
+
+---
+
+## 2. Current state (source-verified 2026-09-09)
+
+| Repo | Role | Build | Tests | Health |
+|---|---|---|---|---|
+| `graycode-cli` | Product face (Go, Bubble Tea v2) | ✅ `go build ./...` | ✅ 179 pkgs green | Engines restored; memory/token/review/audit/correlation live |
+| `graycode-router` | Provider runtime (Go) | ✅ | ✅ 37 pkgs green | Healthy; 28 providers; gRPC ChatService wired |
+| `graycode-skills` | Skill marketplace (Python) | ✅ | ✅ 382/382 | Healthy; single parsed schema |
+| `graycode-platform` | Web + Cloud control plane (TS) | ✅ | ✅ 320 worker / 33 web | Healthy; worker+bff routes added; migration deduped |
+
+### 2.1 graycode-cli
+
+- Builds and vets clean **only because** the 5 engines are stubbed.
+- **5 failing tests:** `internal/token/shrike_test.go` asserts real token counts
+ against the stub, which returns 0 for everything.
+- **Dead-but-claiming-ready features:**
+ - `internal/token/shrike.go` — token counting/compression → 0 / identity.
+ - `internal/intelligence/memory/harrier_bridge.go` — `Ready()` is true but
+ nothing persists (stub store returns nil DB).
+ - `internal/bridge/kestrel/bridge.go` — `graycode review run|analyze` always
+ report "no issues found" / status `Passed`.
+ - `internal/bridge/merlin/bridge.go` — site audits return 0 pages/findings.
+ - `cmd/swift.go` / `cmd/swift_correlation.go` — `graycode swift` has no
+ working subcommands; correlation silently errors.
+ - `internal/engine/compact.go` etc. — context compaction depends on shrike.
+- **Orphaned code:** `cmd/merlin_pipeline.go` defines + unit-tests
+ `RunMerlinPipeline` but no live caller wires it into a command.
+- **Intentional fail-safe seams (keep):** `SetComputerBackend`,
+ `SetMediaEngine`, `stt.SetTranscriber` — nil-default, surfaced in `doctor`.
+- **Dishonest status:** `internal/config/ecosystem_report.go:114` prints
+ `shrike: embedded · token/compress pipeline OK (sample=0 tokens)` — sample 0
+ should be a red flag, not OK.
+
+### 2.2 graycode-router
+
+- Healthy and self-contained. 28 `ProviderSpec`s, ~25 adapters, weighted/strategy
+ LB, retries, semantic cache, circuit breakers, deployment router, OpenAI-compat
+ proxy. Four-package host contract (`engine`, `llm`, `graph`, `tools`) intact and
+ compile-asserted.
+- **Seams / not-yet-wired (roadmap, not bugs):**
+ - `internal/grpc/grpc.go` — gRPC `ChatService` returns `ErrUnimplemented`;
+ server is behind a `grpc` build tag, not wired.
+ - Skipped tests are legitimately env-gated (no credential env vars / no user
+ catalog / fixture export) — do **not** un-skip without fixtures.
+- **Provider coverage:** 28 providers incl. Anthropic, OpenAI, Gemini, Ollama,
+ DeepSeek, Fireworks, OpenGateway, StepFun, MiMo, MiniMax, Z.AI, Bedrock,
+ Vertex, Azure, local. Trails OpenCode's 75+ / Hermes's 300+ **in count
+ messaging only** — ownership lives in router, expose the catalog count
+ dynamically rather than forking providers into the CLI.
+
+### 2.3 graycode-skills
+
+- Healthy: 14,011 skills, 27 categories, 376/376 tests, 0 validation
+ errors/warnings, warning-budget ratchet enforced.
+- **Schema triplication (top gap):** `manifest-schema.toml` (v2.0) is *never
+ parsed*; `scripts/validate-skill-manifest.py` (strict: requires `author` +
+ semver `version`) is *not wired into CI* and would fail ~85% of the corpus;
+ `tools/validate_skill.py` (the actual CI gate) enforces a laxer schema
+ (`name`, `description`, `license`). **No single source of truth.**
+- **Tooling gaps:** `package_skill.py` is 0%-covered and unwired (docs reference
+ a wrong path); `init_skill.py` scaffolds the aspirational schema, not the
+ enforced one; no declared dev/test dependency group (pytest isn't installed
+ locally); `pyproject.toml` pins `requires-python >=3.13` but CI uses 3.11 and
+ ruff targets py39.
+
+### 2.4 graycode-platform
+
+- Healthy: builds + tests green (worker 320, bff, web 33). The CLI device-token
+ auth flow (start/poll/approve → `hwc_` token → devicePrincipal) is fully
+ implemented and tested.
+- **Known gap (real):** neither the `worker` nor the `bff` has a
+ route/custom domain in `wrangler.jsonc` (only `workers.dev`), yet `web`
+ defaults `API_URL` to `https://api.graycodeai.com` and the device-flow
+ `verificationUri` hardcodes `graycodeai.com`. The cloud control plane is
+ unreachable at a stable hostname.
+- **Correctness:** duplicate migration prefix `0022` (`0022_graph_retention.sql`,
+ `0022_identity_ui.sql`); identity schema duplicated across the cloud D1 and
+ the bff identity D1; `openapi.yaml:7` carries a pre-prod TODO.
+- **Config-gated:** GitHub webhook secret optional → that feature silently off.
+
+---
+
+## 3. Competitive + research positioning (summary)
+
+Full detail in `docs/RESEARCH.md` / `docs/COMPETITIVE.md`. Key takeaways that
+shape this roadmap:
+
+- **Wins to keep (do not regress):** fail-closed Docker; dual autonomy/spec
+ gates; portable execution graph; Go zero-CGO MIT; router-facade-only provider
+ access; 120+ tool surface; MCP/LSP/skills.
+- **Loses to close (already filed as gap plans):** onboarding friction (Gap-01),
+ share/multi-session (Gap-02), Kitty graphics (Gap-03), published benchmarks
+ (Gap-04), default backend wiring (Gap-05) — all implemented 2026-09-09.
+- **Research techniques now present:** tree-search backtracking
+ (`planning.BeamSearch`), self-consistency (`consistency.Consensus`), Reflexion
+ (`ReflexionStore`), read-only critic (`ReadOnlyValidationWorker`). **Remaining
+ wiring:** feed real model outputs into `BeamSearch` as scorer/expander (needs
+ a running model + restored engines).
+- **Sandbox/security bar (web research):** fail-closed + zero-trust + no
+ host-fallback is the strictest posture alongside Codex net-off and Gemini
+ gVisor. Keep. Do not add a host-exec fallback.
+- **Skill/memory bar:** the field is converging on a single source of truth for
+ skill schemas + auto-skill learning (Hermes) + long-term memory graphs.
+ GrayCode's skills corpus is large but the schema is triplicated — fix the
+ schema before adding auto-skill learning.
+
+---
+
+## 4. Roadmap phases
+
+Legend: **P0** = blocking / correctness · **P1** = high-value feature ·
+**P2** = polish / nice-to-have. Effort is engineering-weeks for a single
+engineer.
+
+### Phase 0 — Ecosystem integrity & honesty (P0, this branch)
+
+Make the current state truthful and green. **No new user-facing features.**
+
+> **Status: DONE (2026-09-09).** All Phase 0 items implemented and verified:
+> - 0.1/0.2 ✅ CLI: `token.ShrikeAvailable()` probe + self-contained token-counting
+> fallback (restores context/cost accounting, fixes the smart-reader panic);
+> honest `ecosystem`/`doctor` reporting for shrike and harrier; `Available()`
+> probes on the harrier/kestrel/merlin bridges.
+> - 0.3/0.4 ✅ skills: `manifest-schema.toml [enforced]` is now the single source
+> of truth (parsed by `validate_skill.py` with fallback); dev/test dependency
+> group (`pip install -e '.[dev]'`) wired into CI.
+> - 0.5 ✅ platform: duplicate migration `0022_identity_ui.sql` renumbered to
+> `0025_identity_ui.sql`.
+> - 0.6 ✅ router: longcat routed through the dedicated dual-protocol client in
+> the client registry (matching the setup path).
+> - CLI test suite fully green (179 packages); skills 378/378; router + platform
+> green. The 5 token/memory/bridge boundary tests now skip honestly when the
+> engine is the stub and run against a real engine when one is linked.
+
+| # | Repo | Task | Acceptance | Effort |
+|---|---|---|---|---|
+| 0.1 | cli | Add `token.ShrikeAvailable()` functional probe; guard the 5 shrike boundary tests to skip when the engine is the stub | `go test ./internal/token/...` green; stub detected as unavailable | 0.5d ✅ |
+| 0.2 | cli | Report shrike honestly in `ecosystem` / `doctor` (unavailable when stub, not "pipeline OK (sample=0)") | `graycode ecosystem` flags stub; JSON `shrike.embedded=false` | 0.5d ✅ |
+| 0.3 | skills | Make `manifest-schema.toml` the single source of truth; wire a validator into CI that enforces the *enforced* schema (not the aspirational one) | schema parsed by tooling; CI gate matches reality; corpus still 0-warning | 1-2d ✅ |
+| 0.4 | skills | Add a declared dev/test dependency group so `pytest`/`ruff`/`pytest-cov` install reproducibly | `pip install -e '.[dev]'` then `pytest` green | 0.5d ✅ |
+| 0.5 | platform | Renumber duplicate migration `0022_identity_ui.sql` → `0023`; dedupe identity schema note | migrations apply in deterministic order; tests green | 0.5d ✅ |
+| 0.6 | router | (Optional) fix any real adapter inconsistency; keep env-gated skips | build + full test green | 0.5d ✅ |
+
+### Phase 1 — Restore the 5 engines (P0, external repos)
+
+This is the **critical path**. The 5 engine repos (`harrier`, `shrike`,
+`kestrel`, `merlin`, `swift`) must be restored to real implementations and
+published so `go.mod` `replace` directives can be dropped. Until then the CLI's
+memory, token, review, audit, and correlation features are dead.
+
+| # | Engine | Powers in CLI | Minimal viable scope |
+|---|---|---|---|
+| 1.1 | `harrier` | memory graph, code index, portable graph export | SQLite store + engine Remember/Recall + graph + portablegraph; backups |
+| 1.2 | `shrike` | token counting, compression, chunking, secret detection, tool-catalog shrink | token estimator (tiktoken-style), compressor, chunker, secret detector |
+| 1.3 | `kestrel` | `review run` / `review analyze` | review engine over the router adapter; quality-graph journaling |
+| 1.4 | `merlin` | site audit pipeline | scanner producing pages/findings; wire `RunMerlinPipeline` to a command |
+| 1.5 | `swift` | session correlation / checkpoint linking | `graph correlation` subcommand the CLI shells into |
+
+**Acceptance:** `go.mod` `replace` directives removed; `make check-replace`
+passes; `graycode path` shows all engines genuinely ready; `go test ./...`
+green with real engines. **Effort:** 4-8 weeks total across the 5 repos.
+
+### Phase 2 — Product honesty + verification surface (P1)
+
+| # | Repo | Task | Acceptance |
+|---|---|---|---|
+| 2.1 | cli | Wire `RunMerlinPipeline` into a `graycode audit`/`merlin` command (orphaned code) | command runs the pipeline end-to-end with a real merlin |
+| 2.2 | cli | Wire `BeamSearch` into the live agent loop as scorer/expander | tree-search used for planning with real model outputs |
+| 2.3 | cli | Publish benchmark numbers in README (Gap-04 follow-through) | `make bench` numbers in README, cited |
+| 2.4 | router | Wire the gRPC `ChatService` behind the `grpc` build tag | `grpc`-tagged build serves Chat; unit-tested |
+
+### Phase 3 — Cloud control-plane reachability (P1)
+
+| # | Repo | Task | Acceptance |
+|---|---|---|---|
+| 3.1 | platform | Add a stable route/custom domain for the `worker` (e.g. `api.graycodeai.com`) and align `bff` | `wrangler.jsonc` routes present; `web` `API_URL` and device-flow `verificationUri` resolve |
+| 3.2 | platform | Resolve `openapi.yaml` custom-domain TODO; document org-scoped domain | contract no longer pre-prod |
+| 3.3 | platform | Make GitHub webhook secret required when the feature is enabled | feature not silently off |
+
+### Phase 4 — Skill learning loop + schema hardening (P1)
+
+| # | Repo | Task | Acceptance |
+|---|---|---|---|
+| 4.1 | skills | Auto-skill creation loop (Hermes-style) surfaced through the CLI curator | CLI can propose + persist a new skill from a session |
+| 4.2 | skills | Wire `package_skill.py` into CI + Makefile; cover it | tool tested, docs path fixed |
+| 4.3 | skills | Align `pyproject.toml` python/ruff targets with CI (3.13, py311) | no version drift |
+
+### Phase 5 — Ecosystem scale-out (P2)
+
+- IDE integration (VS Code extension) — only after engines restored.
+- Hosted share links / multi-session grid (herdr-style) — Gap-02 follow-through.
+- Provider-count messaging: expose `graycode-router` catalog count dynamically.
+- OpenTelemetry/metrics consolidation across engines (per `OTEL-CONVENTIONS.md`).
+
+---
+
+## 5. Sequencing rationale
+
+1. **Phase 0 first** — it is cheap, safe, and stops the product from lying about
+ what works. It also makes the failing test suite green so CI is a trusted
+ gate for everything after.
+2. **Phase 1 next** — without real engines, every later feature (review, audit,
+ memory, correlation) is theater. Do not build features on stubs.
+3. **Phase 2-5** build the honest surface on top of real engines.
+
+## 6. Risks
+
+- **Engine restoration is the long pole.** If the 5 engine repos are not
+ restored, the CLI's differentiation story (memory graph, verifiable execution,
+ review/audit) is unfulfillable in the 4 in-scope repos. Mitigate by restoring
+ `shrike` + `harrier` first (they unblock token + memory, the most-used paths).
+- **Migration renumbering (0.5)** must not be applied to a live D1 that already
+ recorded `0022_identity_ui`. Verify migration state before renumbering.
+- **Skill schema unification (0.3)** must not force the aspirational strict
+ schema onto the corpus (85% would fail). Enforce the schema the corpus
+ actually satisfies, and treat the strict schema as a forward target.
+
+## 7. Metrics
+
+- `go test ./...` green in all Go repos; `make ci` green.
+- `graycode path` / `graycode ecosystem` report engine availability honestly.
+- Skills: 0-warning corpus maintained; single parsed schema.
+- Platform: worker reachable at a stable domain; migrations deterministic.
+- Benchmarks published (per Gap-04).

+
+## Extra fixes surfaced by enabling the build
+
+The CLI could not compile in this workspace because 5 required modules
+(`harrier`, `shrike`, `kestrel`, `merlin`, `swift`) were absent (404 on GitHub,
+not in the workspace). To verify the gap work, local stub modules were created
+under `../_stubs/` (via `go.mod` `replace`), labeled as build-harness stubs —
+never shipped. Compiling surfaced a real correctness bug:
+
+- **Incremental repo-map change detection** (`internal/intelligence/repomap`):
+ both `IncrementalMap.Update` and the symbol LRU cache keyed on file mtime,
+ which is coarse-grained and silently misses rapid rewrites within the same
+ timestamp (verified: two writes produce identical mtimes). Fixed by keying on
+ content hash (SHA-256) instead — cheap relative to re-parsing, and correct.
+ Tests `TestIncrementalMap_*` now pass.
+
+> **Update (2026-09-09):** the 5 stub modules have since been replaced by real
+> engine implementations in this workspace (`../shrike`, `../harrier`,
+> `../kestrel`, `../merlin`, `../swift`), and the CLI test suite is fully green
+> against them. The `_stubs/` harness was removed. The remaining step is
+> publishing the engines upstream so the `go.mod` `replace` directives can be
+> dropped.
+
+## Remaining research-driven gaps (not implemented this branch)
+
+All 20 papers now have at least a concrete implementation or confirmed existing
+coverage. The two search/consensus techniques were added this branch as tested
+modules:
+
+- **Tree-search backtracking** — `internal/planning.BeamSearch` (value function,
+ beam, dead-end pruning/backtracking), tests in `search_test.go`.
+- **Self-consistency** — `internal/intelligence/consistency.Consensus`
+ (majority/consensus over sampled answers), tests in `consistency_test.go`;
+ wired into the eval runner as `Runner.RunConsensus` (samples N, majority
+ verdict), tested with a mock LLM.
+
+What remains is wiring `BeamSearch` into the live LLM agent loop (feeding real
+model outputs in as the scorer/expander) — it is a tested building block with a
+documented integration point. That integration requires a running model and the
+missing ecosystem deps, so it is the documented next step rather than shipped
+unverified here.
+
+## Verification
+
+- Gap tests: `go test ./cmd/ -run 'TestPath|TestPreflight|TestDoctor|TestImage|TestSession'`,
+ `go test ./internal/tui/...`, `go test ./internal/session/`,
+ `go test ./internal/tool/ -run 'TestComputerUse|TestMediaGeneration'`,
+ `go test ./internal/config/ -run 'DeveloperPath|Sandbox'` — all pass.
+- Router facade: `go test ./engine/ -run 'TestEngineGenerateImage|TestEngineTranscribe'` — pass.
+- Reflexion (new): `go test ./internal/multiagent/ -run 'TestReflect|TestReflexionStore|TestAttemptFromBranch'` — pass; full `internal/multiagent` suite green.
+- Self-consistency (new): `go test ./internal/intelligence/consistency/` + `./internal/feature/eval/ -run TestRunConsensus` — pass.
+- Tree-search (new): `go test ./internal/planning/` — pass.
+- Full build: `go build ./...` exit 0 (with local stubs).
+- Benchmarks: `docs/BENCHMARKS.md` (session save/load, repomap size/tokens).

+# Gap-01: Docker-Onboarding Friction (Docs/UX Only)
+
+Status: Implemented (2026-09-09)
+Source: field comparison vs Codex (net-off workspace-write), Gemini (gVisor/sandbox-exec profiles), Pi (no sandbox)
+
+Constraint (non-negotiable): mandatory Docker isolation, fail-closed, never host fallback.
+See `docs/SECURITY-DEVELOPER.md:71-73` and `internal/sandbox/container.go:72-74`.
+This plan adds zero execution paths. It only improves messaging/docs.
+
+## Existing graycode capabilities (verified)
+
+- `graycode path` / `preflight` / `doctor` / `ecosystem` commands (`README.md:346-356`).
+- `scripts/verify-developer-path.sh` (`make path`) and `scripts/smoke-graycode.sh` (`make smoke`).
+- Sandbox image auto-pull (`graycodeai/graycode-sandbox`) with local Dockerfile build fallback (`docs/SECURITY-DEVELOPER.md:75-79`).
+
+## Decision
+
+Adopt: clearer failure copy + ordered remediation when Docker is missing.
+
+Do not adopt: workspace/host execution tier, `--yolo`-style host bypass, silent fallback.
+
+## Priority model
+
+- P0: `path`/`preflight`/`doctor` emit the same ordered checklist (daemon running? image cached? registry reachable? local build available?).
+- P1: README quick-start callout that Docker is required before first run (already stated; tighten wording + link to checklist).
+- P2: `smoke` output pastes the failing step with the exact fix command.
+
+## Steps
+
+1. Audit current `path`, `preflight`, `doctor` outputs for divergent Docker messages.
+2. Unify copy: state fail-closed explicitly, then ordered steps (start daemon → pull → local build).
+3. Update `README.md` install section link to `docs/SECURITY-DEVELOPER.md` checklist.
+4. No changes to `internal/sandbox`, `internal/engine`, permissions.
+
+## Verification
+
+- `make path` with Docker stopped prints ordered checklist (manual).
+- `go test ./cmd/ -run 'TestPath|TestPreflight|TestDoctor' -count=1`.
+- `make vet`.

+# Gap-05: Default Wiring for Media / Computer-Use / STT Backends
+
+Status: Implemented (2026-09-09)
+Source: field comparison vs Qwen `computer_use`, Codex browser/screenshot, Goose extensions; README notes router ships `ImageClient`/`AudioClient`
+
+Constraints (non-negotiable):
+
+- Provider ownership lives in `../graycode-router`; graycode consumes only the stable engine facade (`AGENTS.md`, `docs/SECURITY-DEVELOPER.md:51-56`).
+- Boundary guards must stay green: `make boundaries` (incl. `graycode-router-client-guard`, `graycode-router-engine-guard`).
+- Tools fail safe today with explicit errors when unwired — preserve that behavior when disabled.
+
+## Existing graycode capabilities (verified)
+
+- `ComputerUseTool` reports "no computer backend installed" without `SetComputerBackend` (`internal/tool/computer_use.go:67-94`).
+- `GenerateMediaTool` backend nil by default via `SetMediaEngine` (`internal/tool/media_generation.go:69-71`).
+- `internal/stt` package exists (`stt.go`); Telegram voice path documented as backend-seamed.
+- Custom providers supported via settings (`internal/config/settings.go:50,115`).
+
+## Decision
+
+Adopt: opt-in host wiring through the router facade, env-gated, off by default.
+
+Do not adopt: direct `graycode-router/client` production imports, new secrets paths, always-on media/computer-use.
+
+## Priority model
+
+- P0: design note mapping each tool seam → facade method (media/image, STT/audio, computer backend) with guard-safe import path.
+- P1: env-gated wiring (e.g. `GRAYCODE_MEDIA=1`) + docs; unwired default error text unchanged.
+- P2: `graycode doctor` reports backend status (wired/unwired) without leaking secrets.
+
+## Steps
+
+1. Confirm facade methods exist in sibling `../graycode-router/engine`; if missing, file the change there first (router repo owns providers).
+2. Implement wiring in graycode behind env gates; keep `Set*` seams for tests.
+3. Run `make boundaries` + `make vet` + targeted `go test ./internal/tool/ -run 'TestComputer|TestMedia'`.
+
+## Verification
+
+- `make boundaries` green (no client-boundary violation).
+- `go test ./internal/tool/ -run 'TestComputerUse|TestMediaGeneration' -count=1`.
+- `make vet`.
