Errors are typed JSON bodies — +`{kind, message, status, retryAfter?}` with kinds `rate-limit` (429), +`not-found`/`invalid-document` (404), `upstream` (502), +`invalid-path`/`invalid-query`/`invalid-body` (400), drafts' `too-large` +(413), `rate-limited` (429) and `unavailable` (503) — so nothing the Worker fails at can +turn into a 500 for an agent to choke on. `downloads` (90-day install +counts) is attached when `CF_ACCOUNT_ID` + `CF_ANALYTICS_TOKEN` are set, and +absent when not: counts are never zero-filled. + +## The scheduled index (and the free plan's subrequest and write budgets) + +A Cron Trigger rebuilds the catalogue every 15 minutes (`*/15 * * * *`, in +`wrangler.toml`) into KV: one entry per listed document, its validated JSON +and README, and the removal list. The request path reads only KV (plus the +bundled pattern pages below), so traffic never spends GitHub quota. + +The Worker runs on the Workers **Free** plan: one invocation may spend **50 +subrequests**, and a Cache API lookup or store is one of them. The indexer +therefore keeps to a single constant, `SUBREQUEST_BUDGET = 45` in +`src/indexer.ts` — the plan's 50 minus the margin the KV writes and the +answer need — which caps **every** outbound call of one run: GitHub REST, +GraphQL and the discovery search. + +| Run | Transport | Cost of the official repository | +|---|---|---| +| `GITHUB_TOKEN` set | one `POST https://api.github.com/graphql` per repository | 1 subrequest for every document and README | +| no token | REST contents and raw URLs | 2–4 calls per folder, so the budget may stop it early | + +KV has a budget too, and it is the tighter one: the Free plan allows **1,000 +KV writes a day** per account, while the cron wakes 96 times. So the indexer +fingerprints what it writes — one SHA-256 digest per key in `index:hashes:v1` +(`src/hashes.ts`) — and skips any put whose value is unchanged; +`index:v1` is fingerprinted without its `built_at`, so +an untouched catalogue keeps its timestamp and a whole run costs **one write** +(`index:meta`, which shows `kv_writes` and `kv_skipped` at +`/api/index-status`). + +The GraphQL query asks for the two top-level folders (`graphs/`, `nodes/`) +and `blocked.json`, three entry levels deep, and nothing else in +the repository. The scheduled transport is built with `cache: null`, so the +cron path never touches the Cache API — the request path keeps its cache +exactly as before. + +When the budget, a rate limit or an unreadable answer stops a run, it still +writes what it read, **carries over** the previous entries of every +repository it did not reach, and never shrinks the catalogue. `GET +/api/index-status` shows `subrequests` (the calls spent) and `stopped` (why +the run ended early, or `null`), so a truncated run is visible without +`wrangler tail`. + +The visit is incremental: one KV key, `index:repos:v1`, remembers each +repository's `pushed_at` and when a run last visited it, and a run visits +only the repositories that changed or were never read — pending ones oldest +visit first (never visited before anything else), so a run cut short by the +budget is resumed by the next one and no repository starves, while an +unchanged catalogue costs the official read plus discovery. Unchanged +repositories keep their entries with a star count refreshed from the search +hit at no cost; the official repository is still read in full on every run. +`GET /api/index-status` shows `repos_visited` (visited this run), +`repos_unchanged` (skipped) and `repos_pending` (left for later runs), and +`truncated` is true while any repository is still pending. + +## Pattern pages + +The `/patterns` pages are editorial content of this site, authored in this +repo under `apps/graphs/patterns/`: one `.md` (front matter plus a +markdown body) plus the `.figure.json` its `figure:` key names — a +harness-free graph document the plate renderer draws. The front matter +carries exactly six keys (`title`, `summary`, `status`, `implements`, +`figure`, `sources`); the strict shape lives in `src/patterns.ts`. + +`npm run build:patterns` validates every page with those same rules and +regenerates the committed `src/patterns-data.generated.ts` the pages +render from. A malformed page, a missing figure, or a figure that fails +the graph schema fails the build — patterns are never fetched from +GitHub and never touch the indexer's quota. `tests/patterns-build.test.ts` +fails when the generated module is stale, so editing a page without +rebuilding is caught. + +## Agent discovery + +The catalogue is a public index agents should read, so it speaks the same +discovery dialect as univerlab.org (same robots wording, same `Link` shape): + +| Route | Answer | +|---|---| +| `GET /robots.txt` | crawl the catalogue, skip `/i/`; `Content-Signal` grants search and input, not training (third parties authored the documents) | +| `GET /sitemap.xml` | `/`, `/search`, `/publish`, `/patterns`, `/llms.txt`, `/auth.md` plus every indexed document's page, from the scheduled index — never GitHub | +| `GET /.well-known/api-catalog` | RFC 9727 linkset: the OpenAPI description, the Publish docs, the index status | +| `GET /.well-known/ai-catalog.json` | ARD manifest: the catalogue, the skills index, `llms.txt`, the OpenAPI description | +| `GET /.well-known/agent-skills/index.json` | the `canopy-graph-design` skill, with its URL and digest | +| `GET /auth.md` | reads need nothing; publishing and reporting ride on a GitHub account, never a catalogue credential | + +Every HTML page carries +`Link: ; rel="describedby"; type="text/plain", ; rel="api-catalog"; type="application/linkset+json"`, +registers the `search_catalogue`, `get_graph` and `get_node` WebMCP tools, +and every other `/.well-known/*` path answers `404`.

The document goes through the same +validator `npm run validate` uses, plus the harness-free rule: `platform`, +`model` and `cli` are refused (in a node's config, in a graph node's config and +in an ensemble member). A body over 256 KiB is a 413; an invalid document is a +400 whose `problems[]` carries each JSON pointer. `POST /api/drafts` is limited +to 10 per minute per client IP by a Workers rate-limiting binding, and answers +429 with `Retry-After` beyond that. Draft pages carry `noindex` and never appear +in search, `/llms.txt` or `/sitemap.xml`. + +Drafts are the one deliberate exception to "the Worker never serves +documents": they are short-lived, labelled unreviewed, and validated before +they are stored, so GitHub stays the download origin for everything published. +**KV deletes are eventually consistent**, so "one use" is best effort: the +install deletes the key, but a second install within about a minute can still +read it, and the key expires on its own at 30 minutes regardless. + +A draft with an unknown, spent or expired id answers 404 with a page that says +drafts last 30 minutes or one install. Storage lives in `src/drafts.ts`; the +`/d` page renders through the document page renderer in `src/pages/routes.ts` +rather than a second template. + +## Tests + +```sh +npm run test:worker # apps/graphs suite, in the Workers runtime via Miniflare +``` + +The suite covers both route shapes, `?ref=`, every 400 case, the `/i/` usage +page, the data point written for each outcome, and that a throwing or missing +binding still serves the redirect, plus the API surface above: official +listing, search with text and both orderings, invalid documents dropped, a +cache hit on a second call, rate limits surfaced as typed errors, and counts +present and absent. `npm test` runs it together with the document validator +suite. The API tests use injected fakes (`apps/graphs/test/fakes.ts`), +never stubbed globals. `drafts.test.ts` covers the whole draft path: create, +read, install, gone; the 1800-second TTL; invalid documents with their paths; +harness bindings; the 413 and the 429; the page banner, `noindex` and the +promise that viewing never consumes; and that no draft reaches search, +`llms.txt` or the sitemap. + +## Proving the Meta review locally (before production is ever enabled) + +The `meta` review provider is proven from the laptop before `REVIEW_PROVIDER` +is ever set to `meta` in production.

Any document JSON works +as the fixture; `--kind=node --owner=acme --repo=things --slug=cool` overrides +the local coordinates.

The graph never learns which file woke it, so the intake reads a fixed path and watching a directory does not work today. The script must be idempotent, or the same issue rewritten produces the same spec twice.

Tests are durable by nature; a design document is not unless someone + writes it down. + +Design the chain short, or give it durable ground to stand on. See +`references/graph-patterns.md` → pattern 9. + +**Spec notes are the shared working memory.** Every spec carries one note per +owner (per node, or per ensemble when the writer is a member). A node records +its plan, decisions or open questions with `spec_edit` `note_write` +(`run_id`, `body`) +(body at most 2 500 characters). Every later agent node of the same spec +receives the notes in a `[SPEC NOTES]` section (5 000-character budget, never +truncated mid-note), so a Designer's plan reaches the implementer without a +temp file. Notes survive bounces, resumes and `graph_control` `continue`. +`graph_control` `reset` keeps them unless `clear_notes: true`. Read a spec's notes with +`spec` `notes` or `canopy spec notes `. + +--- + +## Ensembles: a crew instead of one model 🔴 + +A single agent node dies with its platform: one quota reset, one gateway +outage, and the spec fails. An **ensemble** puts several members (each its own +platform + model, optionally its own `prompt_override`) behind one logical +step, created with `graph_ensemble` `add` and reshaped with +`graph_ensemble` `update` without touching member nodes. Three kinds: + +| Kind | Behaviour | Use it for | +|---|---|---| +| `parallel` (default) | Every member runs; the step passes when `min_pass` of them pass. | Review panels where independent votes matter; give members different `prompt_override` angles (correctness, security, conventions). | +| `round_robin` | One member per entry, rotating on every re-entry. | Designer, implementer, reviewers: a bounce lands on a *different* model with fresh eyes, and quota spreads across platforms. | +| `cascade` | Members in order; the first pass wins. | The committer: a cheap reliable model first, fallbacks behind it. | + +Rules: + +- **Mix platforms in every ensemble.** Members on one platform share one quota + and die together. Before a run, `graph_control` `preflight` probes every distinct + platform+model pair; replace a pair it reports broken before launching, not + after the first failure. +- **A crew is a snapshot of today's quota, not part of the design.** Which + platforms have quota changes from week to week: subscriptions run dry, + weekly limits reset, free tiers come and go. Pick members right before each + launch, or before resuming a paused graph, from what is available at that + moment. Then run `graph_control` `preflight`. Give graphs that run at the same time the + same crew, so a provider outage hits them alike and one fix covers both. Do + not rewrite the crews of idle graphs in advance: an idle graph's crew is + chosen when it next runs. When a provider's quota comes back, its models go + back into the rotation. +- **Exactly one commit holder.** `commit_rights` marks the ensemble (or node) + allowed to write git history; every other prompt says "never commit". +- **Chain without relay nodes.** `on_pass_to`/`on_fail_to` accept another + ensemble's id, and `add_entry_from` lets several nodes enter one ensemble + (a failing gate and a bouncing reviewer both entering the implementer). +- **Order members by cost of a wasted turn.** In a `round_robin` the first + member takes the first attempt: put the strongest model where a wrong first + attempt is expensive (the designer), the cheapest where attempts are mostly + mechanical (the committer). +- The attempt ceiling applies per ensemble: 5 entries per spec per run + (`graphs.max_iterations_per_node`). +- **Member caps are per kind and configurable.** A `parallel` ensemble takes + 2–8 members by default (`graphs.ensemble_max_members_parallel`, up to 16). A + `cascade` or `round_robin` takes 2–16 (`graphs.ensemble_max_members_sequential`, + up to 32). Do not assume the old fixed 8. +- **Bind a crew instead of copying members.** A crew is a named, ordered member + list (`crew` `create`). An ensemble or node binds it with `crew: "name"` (the + node config, or `graph_ensemble` `add`/`graph_ensemble` `update`), so a role's + members are written once. `crew` `update` reaches every bound ensemble at its + next dispatch. `crew` `delete` is refused while anything binds the crew. Use + `crew` `assignments` to see every harness/model a graph uses, with no prompt text. +- **Unavailable members are skipped, not edited.** Declare a platform or model + out with `harness` `roster_set` (optionally `until`). Dispatch then skips it: a parallel + quorum counts only the available members, cascade falls through, and + round_robin steps over it. An ensemble with too few members left blocks the + spec, with a blocker that names the pair. It does not burn an attempt. Clear + the entry with `harness` `roster_clear`. `graph_control` `preflight` never probes an unavailable + pair. + +--- + +## Hooks: what happens after 🟡 + +A graph's work is not finished when its last node passes: someone has to know, +and often something else has to start. `graph_edit` `update` takes an event-keyed +`hooks` map (`on_spec_completed`, `on_completed`, `on_failed`, `on_blocked`), +each an ordered list. Each hook is exactly one mode: + +- **command** — a shell line with the `CANOPY_HOOK_*` variables exported + (`GRAPH_NAME`, `SPEC_NAME`, `NODE`, `BLOCKER`, …). **Never start a canopy + binary from a hook**: daemon-startup recovery kills live runs, including the + one that fired the hook. Do not use a hook as a run log either: the engine + already records the history. Read it with `graph` `events` (or + `canopy graph log`), so no `printf >> file` hook is needed. +- **interactive** — a prompt delivered into a live session by + `target_session_name` (resolved by name on every fire) or by + `target_session_id` (exact; it survives a restart or resume canopy + recognizes — same id, same name — but a resume canopy does not recognize + comes back as a new session with a fresh id and a fresh generated name, + and firing then fails naming the old id). Prefer the name. Use it to + wake the orchestrating session on `on_failed` / `on_blocked` with `{{node}}` + and `{{blocker}}`, and on `on_completed` with what to review. The daemon's + scheduler delivers the message on its next tick whether or not a TUI is + attached; if the target session is gone by then, the prompt is preserved + for recall in that project and a notification says the session was not + found. The target session itself keeps running in the daemon meanwhile. +- **graph** — `target_graph_id` launches another graph in-process, with a + `queue_id` or an `idea`. Use it to chain phases (pattern 10: a spec graph + hands its branch to a spec-less quality graph). +- **agent** — a one-shot agent run with platform/model/prompt. + +Hooks are not retroactive: one registered after its event fired does not fire. +Hooks are read when each event fires, so a `graph_edit` `update` of hooks on a running +graph changes the events still to come. The response names those events. A +failing hook is recorded and never changes the graph's status. + +--- + +## Core Rules + +### 1. Model processes as graphs, not lists + +- `agent` — produces or analyzes work +- `check` — verifies with commands or deterministic checks +- `gate` — decides the next route based on prior output +- `router` — routes by token matching. With `"decision": true` it asks the + platform's decision model (a typed-choice classifier, no agent spawned) which + declared route to take, with an optional `min_confidence` that sends + low-confidence answers to the fallback. The platform must declare + `decision_args` in the registry, or the node is refused. + +If the graph needs iteration, use edges and gates. If it is linear, keep it +simple. + +### 2. Preserve genericity + +Never assume one CLI platform, one model vendor, one review style, or one +commit strategy. Any node may use Copilot, OpenCode, Kimi, local MCP-driven +agents, or other supported CLIs. Design prompts and checks accordingly — +platform-specific behavior belongs in the platform registry, never hardcoded +into prompts. + +### 3. Ask before irreversible behavior + +Before you create or run a graph, clarify: draft or run; which verification +commands are authoritative; whether commits are allowed inside the graph; +whether blockers should pause or hard-fail. + +### 4. A graph does not have to be run by hand + +`graph_edit` `create`/`graph_edit` `update` accept an optional `trigger`: **manual** (default), +**cron** (5-field expression, local wall-clock), or **watch** (file/dir +changes with debounce). A one-off migration is almost always manual; a +recurring maintenance sweep is a candidate for cron or watch. See +**[references/mcp-tool-playbook.md](references/mcp-tool-playbook.md)** for the +exact fields. + +### 5. Reuse patterns, adapt prompts + +Reuse graph patterns from +**[references/graph-patterns.md](references/graph-patterns.md)**, but adapt node +prompts, CLI/model selection, verification commands, retry routing, and +blocker behavior to the project. + +### 6. Design for the process dying mid-run + +Loops outlive daemon restarts and PC reboots badly unless you plan for it: + +- A restart leaves the graph `running` with nobody executing it (a zombie). + Recovery is `graph_control` `pause` → `continue` with `mode: retry_current_node` — see the + Recovery Matrix in `mcp-tool-playbook.md`. Scheduled autoruns can NOT + rescue a `running` zombie. +- Resume at (or before) an idempotent node. Deterministic checks that + recompile and re-run tests are safe re-entry points; marker files written + by earlier nodes are stale after a restart. +- Give failure knowledge somewhere to go: a resilience branch (pattern 8) + that triages the failed implement — quota deaths schedule their own + autorun instead of silently losing the reset time. +- A daemon stop or crash finalizes the killed node as **interrupted** and + routes no edge, so its fail edge never fires. On the next start the graph + is `Paused` with the spec `Interrupted`. `graph_control` `continue` with + `mode: retry_current_node` re-runs that same node with the same input. +- A parallel or round-robin ensemble that ends with no verdict pauses with a + blocker and marks the spec `interrupted`, not `failed`. Edit the members if + they are at fault, then `graph_control` `continue` with `mode: retry_current_node`. + A `graph_control` `run` on a blocked graph is refused, so a blind relaunch cannot hide the blocker. +- **Directed run.** When everything before a node is already good, start a + spec at that node: `graph_control` `continue` with `mode: run_from_node` (and + `spec_id`), or `graph_control` `run` with `start_node_id` for the first spec. It + reuses the recorded output of every earlier node and refuses, naming the node, when a reachable + prompt or check needs output that was never recorded, or when an upstream + node's latest run failed. An ensemble member is the exception: it is judged + by the ensemble's quorum — its join node's run for the spec — so a member + that failed while the quorum passed is a satisfied prerequisite, and a + failed quorum refuses the run and names the join. On an idea-driven + graph (run with an `idea`, no bound specs) the same calls resume the stored + idea run — `{{spec_content}}` renders the idea the graph last ran with and + no spec needs naming; an idea graph that has never run is refused, naming + `graph_control` `run` with an `idea` as the way to start one. +- A spec that ends `Failed` or `Interrupted` blocks the next spec on that + workdir only when its recorded dirty paths overlap the ones dirty now; + `Skipped` specs never block, and a record naming files no longer dirty never + blocks. A spec resuming exactly the dirt its own latest run recorded (the + restart-recovery case) proceeds without `allow_dirty_start`. Otherwise + `graph_control` `run` refuses and names the blocking spec: finish, reset or remove + that spec, or set `allow_dirty_start`. +- **Sandboxed runs.** `graph_control` `run` with `sandbox: true` runs the graph in a temporary + git worktree on a `canopy/sandbox-*` branch instead of the operator's + checkout. A completed run removes it only when the branch holds no unique + commits and the worktree has no uncommitted files; a **failed run always + keeps it**, so `graph_control` `continue` resumes inside that worktree (a resume whose + worktree is gone is refused, naming the sandbox id — it never falls back to + the original workdir). Land or discard a leftover sandbox through the + `sandbox` MCP tool — `list`/`get` to inspect (`graph` `get` reports the + graph's newest sandbox as `{id, status}`), then `land` or `discard` + (`discard` needs `force: true` to delete unique commits) — never with a + raw `git merge`, and never relaunch a fresh run over the same work. + +### 6b. Who supervises the graph — the recovery hierarchy + +There are three places recovery logic can live. Order them by determinism, +and push each responsibility as far up this list as it can go: + +1. **Engine guards (deterministic, always right):** boot reconcile of zombie + runs, empty-spec-set launch errors, stale-spec recovery, pool-aware + autoruns. Anything expressible as a state-machine rule belongs HERE, in + the daemon — not in any agent's prompt. +2. **The in-graph resilience node (LLM, language only):** its unique value is + reading prose the engine can't parse — "resets 5:10pm" — and converting it + into one scheduling call. Keep it on a platform that reliably COMPLETES + runs; a resilience that times out is a resilience that doesn't exist. +3. **An external watcher agent (LLM on cron): last resort, and know the cost.** + Field evidence from running one at scale: it saved two overnight runs, and + it also *falsely completed* a graph by relaunching without its pool, left + another stuck in `draft` by resetting and never relaunching, mangled its + own report JSON for hours, and burned a run every 15 minutes to conclude + "healthy". An LLM watcher acts on state it half-understands with tools + that let it half-recover. If you deploy one anyway: give it a closed + decision table, forbid every mutating call not in that table (especially + pool-less `graph_control` `run`), and prefer wiring its enable/disable to the + resilience node so it only lives during recovery windows. + +Rule of thumb: **no LLM in the deterministic part of the critical path.** +When you catch a watcher doing state-machine work, that work is an engine +feature request — file it, don't re-prompt. + +### 7. Checks are hermetic, versioned and cheap + +A check node runs with the user's HOME and environment. Make it safe to run a +hundred times: + +- **Put the gate in the repo** (`scripts/check-*.sh`) and call it from the + node, so agents run the exact same gate before reporting pass and the gate + is reviewed like code. Scope it to the spec's change with + `--changed "{{spec_start_head}}"`. +- **Check commands take markers, not `{{spec_content}}`.** Use `{{spec_name}}`, + `{{spec_id}}`, `{{workdir}}` and the commit markers. They are shell-quoted, so + do not wrap them in other quotes. For the spec text, read + `"$CANOPY_SPEC_FILE"`. For the notes, read `"$CANOPY_SPEC_NOTES_FILE"`. Any + unknown `{{…}}` fails the node before the command runs. `graph_control` + `preflight` reports it first. +- **Never touch state outside the repo**: no tool command that refreshes a + cache from the network, rewrites a user config, or installs a binary. If the + tool under test has such a command, the gate renders or copies around it. +- **Offload what can kill the machine.** A local mutation-testing run once + exhausted memory and took the daemon down with every graph on it; it runs in + CI now, and the graph only waits for the result. +- **Never run the orchestrator itself** (a `canopy` binary) from a check or + hook. + +--- + +## Construction Playbook + +1. **Understand the target outcome** — deliverable, hard constraints, allowed + tools/CLIs, required validations, parallelism. +2. **Split into specs** — ordered, independently understandable, small enough + to validate, each a tagged ``. Bugs before quality work before + features. +3. **Pick a graph shape** — linear, review loop, verify loop, gated implement + (pattern 7), resilience branch (pattern 8), crew graph with a chained + quality pass (pattern 10), or a fusion/join shape. Decide which nodes are + ensembles and wire the hooks. + **Route the implement's success edge with `pass`, never `always`.** +4. **Validate the graph** — read + **[references/graph-validation.md](references/graph-validation.md)** + immediately before creating: entry node, ambiguous edges, timeouts, gate + tokens, PATH resolution. Every rule there broke a real run. +5. **Persist via MCP tools** — prefer **`graph_edit` `import`**, which builds the whole + graph in one call and validates it all-or-nothing; fall back to + `graph_edit` `create` → nodes → edges only when there is no document yet, and + `graph` `export` the result so the next one is a single call. Run + **`graph` `validate`** on any document you did not author, or are about to + hand to someone else — it runs import's checks without writing anything. + A graph already published in the catalogue needs neither document nor + hand-building: **`graph_edit` `install` with `{ref, workdir, ...}`** (CLI + `canopy graph install `) fetches it through graphs.univerlab.org — + which is what counts the install — validates it, installs its bundled + presets and imports it as a new graph in one call. It writes nothing on + the first call: without **`accept: true`** it returns `{needs_review: + true, review}` — every shell command the document runs, every prompt's + first 3 lines and line count, and the attention marks for dangerous + shapes — so show that review to your user, then call again with `accept: + true` (official documents included; never auto-accept). A draft from the + editor (`canopy graph install draft:` / `graph_edit {action: "install", + ref: "draft:"}`, id 26 lowercase base32 characters) is the same flow with + two extra rules: it lives 30 minutes and **one** install — the review + call's fetch consumes it and the daemon parks that body for `accept: + true`, so a refusal or an error means it is gone; ask for a new link + rather than retrying — and nobody reviewed it, so the review you show is + the user's only check. A single reusable node needs neither hand-building + nor a full graph document: + **`node` `install {ref}`** (CLI `canopy node install `) fetches the node + document through the same catalogue and ref grammar, under the same + `accept` gate, then `graph_node + {action: "add", node: "", config_overrides: ...}` (or `graph_ensemble + {action: "add", node: "ensemble-proposers", members: [...]}` for the builtin ensemble, + whose members still need a platform each) instantiates it — an agent + node document carries no harness, so the overrides must supply + `platform` (or `cli`/`crew`). Then `graph_control` `preflight` + before spending a real run. Order, deletes, recovery and the + export/import contract in + **[references/mcp-tool-playbook.md](references/mcp-tool-playbook.md)**. +6. **Summarize before running** — graph name, specs in order, graph, chosen + CLIs/models/checks, and what still needs user confirmation. Only call + `graph_control` `run` after explicit approval or direct instruction. + +--- + +## Authoring Guidelines + +### Agent nodes + +Explicit configs: platform, model, `prompt_template` (e.g. +`{{spec_content}}\n\n{{previous_feedback}}`), `timeout_minutes`. Prompts state +the goal, expected outputs, constraints, and when to report blocker vs fail. + +Placeholders are checked when you write the node, not when a member spawns: +`{{output:}}` must name a node in the same graph — an ensemble has no +readable output, so reference its quorum node — and anything the engine cannot +bind is refused by `graph_node` `add`/`graph_node` `update` (and by +`graph_ensemble` `add`/`graph_ensemble` `update` for the shared prompt and every +override). Escape a marker meant as literal text as `\{{...}}`. + +`prompt_preset` names a preset file (`/prompts/.md`, or a builtin: +`implementer`, `reviewer`, `resilience`), and export bundles every custom +preset the graph's agent nodes reference — the full text travels in the +document's `prompt_presets` array, so a shared graph arrives with working +nodes and no sidecar files. On import each bundled preset is installed when +absent locally; an identical local file is a no-op, and a differing one +refuses the import naming the preset — a locally edited preset is never +overwritten. A preset the document neither bundles nor finds locally still +refuses the whole import, naming every unknown preset. When you hand a document +to another machine, bundle its presets and run `graph` `validate`: it refuses a +`prompt_preset` that is neither bundled nor builtin, so no node of the shared +document depends on a preset that happens to be installed here. `graph_edit` `install` +follows the same refusal rule, and is the only graph call that can replace a +differing local preset on purpose (`overwrite_presets: true`, CLI +`--overwrite-presets`). + +### Check nodes + +Real verification, not vague "looks good" logic: +`cargo fmt --all && cargo clippy --all-targets -- -D warnings && cargo test`, +`npm test`, `pytest tests/auth -q`, domain-specific smoke checks. Cap noisy +output (`| tail -60`) so a 65 KB test log never rides into the next node's +argv. Set `timeout_seconds` explicitly. + +### Gate nodes + +Use gates when routing depends on semantics, not just exit codes. Gate on a +strict token (`APPROVED`), never on a word that can appear in narration. + +### Two reviewers, two questions + +Split review so each reviewer has one checkable question: + +- **Reviewer 1 — presence.** Every numbered requirement located at + `file:line`, every requested test found by name, nothing out of scope. It + does not run anything and does not judge taste. +- **Reviewer 2 — behaviour.** It exercises the change the way a user would + (a release build run in a scratch dir, the output inspected) and fixes what + it finds in the working tree; a deterministic check re-runs the gates and a + check node commits its fixes. + +A presence reviewer that also judges behaviour does neither well; a behaviour +reviewer that never ran the binary has not reviewed. + +--- + +## Progressive Disclosure + +- **[references/graph-patterns.md](references/graph-patterns.md)** — reusable + graph patterns (including pattern 10, the crew graph with a chained quality + pass) + field notes from real failures.

A + real run marked a spec `completed` with no commit behind it that way. +- **`check` sits before the reviewer**, so code that does not build or whose tests + are red never reaches review. Another real run: the reviewer wrote + `CHANGES_NEEDED: Implementation is broken` and the spec was still marked + `completed`, because routing keyed on the run's status, not on the prose. +- **Auto-fixing commands should not bounce work.** Run `cargo fmt --all` (which + rewrites) rather than `cargo fmt -- --check` (which fails). Only genuine + breakage — compiler, linter, tests — should route back to `implement`. +- **The reviewer commits only the files it reviewed.** `git add -A` sweeps a + previous spec's uncommitted leftovers into this spec's commit. +- **Make the reviewer prove the commit.** Its prompt must require + `git log -1 --oneline` before reporting pass. A reviewer once returned + `{"committed": true, "tests_passed": 601}` for a commit that did not exist. + +### Reviewer prompt discipline + +Once `check` runs before the reviewer, green gates say only *"nothing is broken"* — +they say nothing about whether the spec was **honored**. That distinction is the +reviewer's entire job, and it is the thing a cheap model quietly skips. Say so +explicitly: + +- Open with a **zero-indulgence** instruction: do not approve out of courtesy, for + effort spent, or because it "almost" meets the spec. +- State that **green gates are not evidence of compliance**. A missing required + test is `CHANGES_NEEDED` even when the code works perfectly. +- Require a **verdict per requirement**, written out *before* the decision. A + reviewer that must enumerate is a reviewer that must look. +- Make the asymmetry explicit: *"when in doubt, CHANGES_NEEDED — a bounce costs + minutes, a falsely-closed spec costs days."* +- Tell it what its unique contribution is: the deterministic nodes already own + "compiles", "tests pass" and "commit exists". **Judgment is all it adds.** + +Observed limit: with a small/fast reviewer model this raises the floor but does not +guarantee it. In one real run the spec demanded three tests, the prompt said +"verify the three tests", and a free `flash` model approved a diff carrying one. +The deterministic nodes still held — nothing broken merged — but scope compliance +slipped. Budget for that when picking the reviewer's model, or accept the gap +knowingly. + +Trade-off: the reviewer's honesty is still load-bearing for the **commit** itself. +Close that with a fourth node, `review --pass--> check_committed`, routing back to +`implement` on failure. Verify by **comparing `HEAD`**, not by matching the commit +message (the agent may drop the conventional-commit scope) and not by wall-clock +(the previous spec's commit is recent too). + +The engine hands you the comparison point: **`{{spec_start_head}}`** expands to the +HEAD recorded when this spec started, per spec and per run. + +```bash +test -z "$(git status --porcelain -- src/)" \ + && test "$(git rev-parse HEAD)" != "{{spec_start_head}}" +``` + +Earlier revisions of this file taught a marker file (`.git/canopy-prev-head`) +written by the gates node. **That is obsolete** — the marker no longer exists +anywhere in canopy, and it carried a real hazard `{{spec_start_head}}` does not: +the file survived daemon and PC restarts pointing at a stale HEAD, so a resumed +flow could read "HEAD moved" for a commit that never happened. + +## 8. Resilience Branch (triage a failed implement) + +Pattern 7 fails the spec the moment `implement` dies, so **nobody ever reads the +failure**.
