From 89c60640b0c388089503a793251f5690c38e8bca Mon Sep 17 00:00:00 2001 From: Justin Walsh Date: Fri, 29 May 2026 11:15:15 -0400 Subject: [PATCH 01/10] docs(epic-store): design spec for the file-backed Epic store (opt-in hybrid) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Per-repo opt-in `epic_store = "file"` mode: one Markdown file per Epic under `planning/epics/`, recommender state in `.middle/state.md`. PRs and CI stay GitHub-native in both modes ("hybrid"). Workflow bodies, gates, watchdog, hook server, poller — all unchanged: the three existing single- seam interfaces (`GitHubGateway`, `StateIssueGateway`, `GitHubPollGateway`) get renamed (`EpicGateway`, `StateGateway`, `PollGateway`) and gain parallel file implementations behind the same contracts. Bootstrap picks the implementation per-repo from `repo_config.epic_store`. The agent's `blocked.json` flow plugs in at one DI seam (`postQuestion`). Round-trip-pure parser/renderer absorbs #178's class (structurally distinct `question`/`answer` markers) and #180's class (renderer is the sole writer for strict-marker content). Phase split: file-Epic dispatch ships first (~2 wk) with a `mm resume` escape hatch; file-watcher Q&A resume (~1 wk) rides the existing 120s poller cron.

PRs and CI stay on GitHub in both modes ("hybrid"). + +## Context + +Today, middle treats GitHub as the only Epic substrate: Epics are issues, sub-issues are sub-issues, the recommender's queue is a single `` issue, and the agent's questions/answers flow through issue comments. That works, but it couples the workflow to GitHub for the *plan and conversation* parts even when the user already has a local, file-based plan. + +This design adds a **per-repo `epic_store = "file"` mode**: one Markdown file per Epic under `planning/epics/`, with the recommender's state in `.middle/state.md`. **PRs, reviews, and CI stay on GitHub** in both modes — only the Epic *data* and the agent-↔-human Q&A channel move to files. Both modes coexist: a daemon managing multiple repos can run each repo in whichever mode it's configured for. + +The intended outcome: a user with a file-based plan can author Epic files locally and dispatch them through middle's existing workflow machinery, without GitHub serving any Epic-data role. + +## Goals and non-goals + +**Goals** + +- One file per Epic; file is the canonical Epic data + conversation log. +- Per-repo opt-in via config; existing GitHub-mode repos unchanged. +- Workflow bodies, gates, watchdog, hook server, poller — **all unchanged**. +- The agent's existing `blocked.json` flow plugs in unchanged at one DI seam. +- Byte-identical round-trip for the Epic file under dispatcher writes. +- The parity-test guarantee: the same workflow input produces equivalent outcomes through both gateway backends. + +**Non-goals** + +- PRs file-backed. PRs, reviews, and CI status remain GitHub-native in both modes. +- A migration path from GitHub-mode to file-mode for existing repos. YAGNI; if ever needed, a `mm migrate-to-file` follow-up. +- Real-time file watching with `chokidar` or `fs.watch`. Phase 2 uses mtime polling on the existing 120s poller cron — symmetric latency with GitHub-mode comment polling, no extra dependency. +- A new "review" model. Real GitHub PRs handle review entirely. + +## Architecture + +The whole design is built on a single insight: middle already has three GitHub-coupled interfaces, all dependency-injected, all single chokepoints (`GitHubGateway`, `StateIssueGateway`, `GitHubPollGateway` — see `packages/dispatcher/src/github.ts`, `state-issue.ts`, `poller-gateway.ts`). We add **parallel file implementations behind the same interfaces** and **select per-repo at the dispatcher's bootstrap**. + +``` + ┌──────────────────────────────────────────────┐ + │ packages/dispatcher (workflows / recommender│ + │ / poller / gates — UNCHANGED bodies) │ + └────────┬───────────────┬───────────────┬─────┘ + │ │ │ + ▼ ▼ ▼ + ┌────────────────┐ ┌──────────────┐ ┌──────────────────┐ + │ EpicGateway │ │ StateGateway │ │ PollGateway │ + │ (renamed, │ │ (renamed, │ │ (renamed, │ + │ body unchanged│ │ body unch.) │ │ body unch.) │ + └───────┬────────┘ └──────┬───────┘ └────────┬─────────┘ + │ │ │ + ┌─────────────┼─────────────────┼──────────────────┼────────┐ + │ ▼ ▼ ▼ │ + │ ┌─────────────────┐ ┌────────────────┐ ┌───────────────┐│ + github │ │ ghEpicGateway │ │ghStateGateway │ │ghPollGateway ││ + mode │ │ (today) │ │ (today) │ │ (today) ││ + │ └─────────────────┘ └────────────────┘ └───────────────┘│ + │ ▼ ▼ ▼ │ + │ ┌─────────────────┐ ┌────────────────┐ ┌───────────────┐│ + file │ │ fileEpicGateway │ │fileStateGateway│ │filePollGateway││ + mode │ │ (NEW) │ │ (NEW) │ │ (NEW) ││ + │ └─────────────────┘ └────────────────┘ └───────────────┘│ + └─────────────────────────────────────────────────────────────┘ + ▲ + │ selected per-repo at bootstrap from + │ repo_config.epic_store ∈ {"github" | "file"} +``` + +**Three load-bearing properties of this shape:** + +1. The dispatcher daemon runs both modes simultaneously — repo A (`github`) and repo B (`file`) just pick different gateway implementations. +2. The existing interfaces are renamed for clarity (`GitHubGateway` → `EpicGateway`, etc.) but their **method signatures are unchanged**. Implementations differ; consumers don't. +3. The "Epic = numeric issue ID" assumption is the only thing that bleeds through today; it becomes `epicRef: string` (a slug in file mode, the stringified issue number in github mode for back-compat). Additive, back-compat schema migration. + +**What stays untouched:** every workflow body (`implementation.ts`, `recommender.ts`, `documentation.ts`), every gate (`pr-ready`, `checkbox-revert`, `plan-comment`, `verify-on-stop`), the engine + durable recovery (#116), the watchdog (`watchdog.ts`), the session gate, the hook server, the dashboard's DB feed. Change is contained to **interfaces + file implementations + bootstrap wiring + schema migration**. + +## Config schema + +Mode is per-repo, in the existing `repo_config` table. Migration adds three columns (additive, with a back-compat default): + +```sql +ALTER TABLE repo_config ADD COLUMN epic_store TEXT NOT NULL DEFAULT 'github'; +ALTER TABLE repo_config ADD COLUMN epics_dir TEXT; -- file mode only; NULL for github +ALTER TABLE repo_config ADD COLUMN state_file TEXT; -- file mode only; NULL for github +-- existing state_issue_number stays; populated in github mode, NULL in file mode +``` + +User-facing TOML (surfaced by `mm init` / `mm config`): + +```toml +# .middle/.toml +[epic_store] +mode = "file" +epics_dir = "planning/epics" # default if mode=file +state_file = ".middle/state.md" # default if mode=file +``` + +Omit the block entirely → github mode, defaults match today. **All existing repos work unchanged**; migration sets `epic_store = 'github'` for every existing row. + +A second schema migration on the `workflows` table: + +```sql +-- Make epic_number nullable; add string ref. Both populated in github mode +-- (number + stringified ref); only ref populated in file mode. +ALTER TABLE workflows ADD COLUMN epic_ref TEXT; +-- One-time backfill: epic_ref = CAST(epic_number AS TEXT) for existing rows. +UPDATE workflows SET epic_ref = CAST(epic_number AS TEXT) WHERE epic_ref IS NULL; +-- Then enforce NOT NULL on epic_ref (via table rebuild — SQLite quirk). +``` + +The dashboard's DB queries get updated at the same time (~5 sites; mechanical change verified by the existing dashboard test suite). + +## Bootstrap selection + +`build-deps.ts` is the single place that wires the three gateways. The change is one switch: + +```ts +export async function buildImplementationDeps(args: BuildImplementationDepsArgs) { + const repoCfg = readRepoConfig(args.db, args.repo); + const { epicGateway, stateGateway, pollGateway } = + repoCfg.epic_store === "file" + ? buildFileGateways(args.db, repoCfg) + : buildGitHubGateways(args.db, repoCfg); // today's wiring, lifted into a helper + return { + /* …existing deps unchanged… */ + github: epicGateway, + stateIssue: stateGateway, + poller: pollGateway, + }; +} +``` + +`buildGitHubGateways` is today's existing wiring, extracted into a named helper. `buildFileGateways` is new (factory at `epic-store/index.ts`). Both return the same three-interface shape, so every downstream consumer is unchanged. + +## `mm` commands per mode + +| Command | github mode (today) | file mode | +|---|---|---| +| `mm init ` | Creates state issue + label on GitHub | Scaffolds `planning/epics/` + writes empty `.middle/state.md`; no GitHub call | +| `mm doctor` | Checks `gh auth`, state issue exists | Skips state-issue check; still requires `gh` (PRs go there); checks `epics_dir` exists | +| `mm dispatch ` | `` is an issue number | `` is a slug (filename without `.md`); back-compat: numeric also accepted | +| `mm dispatch --epic ` | New flag, works in both modes | New flag, works in both modes | +| `mm resume --answer "…"` | NEW, both modes — manually fires resume signal for a parked Epic | Same — Phase 1 escape hatch before the watcher lands | + +### What `mm init` writes for a file-mode repo + +``` +/ +├─ .middle/ +│ ├─ .toml # epic_store = "file" + paths +│ └─ state.md # empty state file with markers +└─ planning/ + └─ epics/ + ├─ README.md # one-screen explainer + template snippet + └─ .keep # for git +``` + +Zero GitHub calls during file-mode `mm init`. + +## The Epic file format + +`planning/epics/.md` — slug is the file's stem and the canonical Epic reference. + +### Worked example: an authored Epic file (pre-dispatch) + +```markdown + +# CodexAdapter + + + +## Context + +Phase 10 of the build spec.

That structural rule is what kills #180's class for the file path. + +### Byte-identical round-trip invariant + +``` +renderEpicFile(parseEpicFile(body)) === body +``` + +— for any body produced by `renderEpicFile`. Hard invariant; enforced by a property test over fixtures (empty Epic, mid-question, resolved-question + open follow-up, all sub-issues complete). Mirrors the state-issue v1 contract exactly. + +This invariant lets file mode work **safely concurrent** without locking: dispatcher patches conversation entries via the renderer; human edits between markers or inside their `` block. Round-trip purity replaces a lock. + +## The three new file gateways + +### `fileEpicGateway` — implements `EpicGateway` + +A **composite** gateway: Epic-shaped methods served from files; PR-shaped methods delegated to an internal `gh` backend. + +| Method | File mode behavior | +|---|---| +| `listOpenEpics(repo)` | Scan `epics_dir`; parse `` + sub-issue checkboxes; return `{ ref, title, openSubs, closedSubs, labels, adapter }[]`. Skip files marked `closed`. | +| `listIssueComments(repo, ref)` | Parse `` into `IssueComment[]`; `authorIsBot` derived from marker (`question` / `dispatch-event` → bot; `answer` → human) | +| `getCommentAuthor(url)` | Comment URL = `file://#question-N` or `#answer-N`; resolves to `"agent"` or `"human"` | +| `getIssueLabels(repo, ref)` | Read `labels` from `` | +| `postComment(repo, ref, body)` | Append a new `` or `` block via renderer | +| `editComment(commentId, body)` | Patch the matching marker block in place via renderer (used by gates' evidence-comment upsert) | +| `findEpicPr(repo, ref)` | Read `pr:` from ``; if set, delegate to gh for `getPullRequest`; else null | +| `getPullRequest(repo, prNumber)` | **Delegate to gh** | +| `editPullRequestBody(repo, prNumber, body)` | **Delegate to gh** | +| `resolveAgentLogin()` | **Delegate to gh** (`gh api user`) | + +### `fileStateGateway` — implements `StateGateway` + +Smaller surface: + +| Method | File mode behavior | +|---|---| +| `readBody(repo)` | `readFileSync(state_file)` | +| `writeBody(repo, body)` | Atomic write to `state_file` (write-temp + rename) | + +The `applyDispatcherSections` / `renderStateIssue` flow in `state-issue.ts` is unchanged — same parser, same renderer, same byte-identical-round-trip invariant. **Closes #180's class entirely for file mode**: there's no recommender-agent rewriting the In-flight section out-of-band; the dispatcher writes it directly via `renderStateIssue`. + +### `filePollGateway` — implements `PollGateway` + +| Method | File mode behavior | +|---|---| +| `listIssueComments(repo, ref)` | Same as `fileEpicGateway.listIssueComments` | +| `findPrForEpic(repo, ref)` | **Delegate to gh** (PR reviews/CI are still GitHub-native) | +| `findEpicPrLifecycle` | **Delegate to gh** | +| `statusCheckRollup` | **Delegate to gh** | +| `getRateLimit()` | **Delegate to gh** | + +**File-watcher mechanics (Phase 2).** The poller already runs every `POLLER_INTERVAL_MS = 120_000` (per `packages/dispatcher/CLAUDE.md`). For file-mode repos, the poller pass also stats `epics_dir/*.md` and tests `mtime > wait.createdAt` before parsing for new `` content. **Stat-based mtime polling on the existing cron** — no `chokidar`, no extra dependency, no missed-event semantics. Worst-case latency is symmetric with GitHub-mode comment polling (also 120s). + +## How `blocked.json` plugs in (zero workflow change) + +Today's flow: + +``` +agent writes .middle/blocked.json + ↓ +classifyStop → { kind: "asked-question", sentinel: {...} } + ↓ +parkForResume → deps.postQuestion({ repo, epicRef, question, context, kind }) + ↑ + this is DI'd +``` + +`deps.postQuestion` is **already a dependency seam** wired in `build-deps.ts` to a `gh`-backed comment poster. For file mode, `buildFileGateways` wires it to a file-backed writer: + +```ts +const postQuestion: ImplementationDeps["postQuestion"] = async (opts) => { + const epic = await readEpicFile(opts.repo, opts.epicRef); + const nextId = epic.conversation.nextQuestionId(); + epic.conversation.append({ + kind: "question", + id: nextId, + status: "open", + ts: new Date().toISOString(), + body: opts.question + (opts.context ? `\n\n${opts.context}` : ""), + questionKind: opts.kind, // "question" | "complexity" + }); + await writeEpicFile(opts.repo, opts.epicRef, epic); +}; +``` + +That's it. Every upstream concern — `classifyStop` → `asked-question`, `parkForResume` arming the resume signal, `awaitNextStop` racing session-end, the whole watchdog self-heal — **continues to work unmodified**. The agent's `blocked.json` is mode-agnostic; the only mode-aware step is the comment-write itself. + +The poller's resume side is symmetric: existing `classifyNewHumanReply` filters `!authorIsBot && createdAt > sinceMs`. `filePollGateway.listIssueComments` returns conversation entries with `authorIsBot=false` only for `` blocks (which by definition are human-written, marker says so). New answer with `mtime > sinceMs` fires the resume signal exactly like a new GitHub comment. + +## PR ↔ Epic linkage + +PR body carries ``. `findEpicPr` matches that marker. The Epic file's `` block also stores `pr: ` (stamped once when the PR opens) as a durable backup if the PR body marker is ever lost. + +Zero collision risk with real GitHub issues (`#` is not used as the reference in file mode). + +## Cross-Epic blocked-by + +Today the recommender shows "#124 blocked on #60" by reading sub-issue parent/child via GitHub. In file mode, the same relationship uses a slug reference: + +```yaml + +``` + +The recommender's graph builder reads `blocked-by` slugs from each file's meta. Recommender skill update + small graph helper. In scope for Phase 1. + +## Skills + +Three skills need work. The pattern in each: abstract the *workflow body* (mode-agnostic — "fetch the Epic", "comment the plan on the Epic", "close the sub-issue with evidence"), and pull the per-mode incantations into a separate Commands section or `references/-mode-commands.md` file. + +- **`implementing-github-issues`** — refactored: abstract body talks about "the Epic" mode-agnostically; per-mode Commands section at the end (or `references/file-mode-commands.md`). The dispatch-brief generator (`ensurePromptFile`) injects the right Commands snippet into the agent's `prompt.md` based on the run's mode. +- **`recommending-github-issues`** — same abstraction; file-mode commands scan `epics_dir` and write the state file via the renderer (not by hand — closes #180 for this skill too). +- **`creating-github-issues`** — gets a file-mode variant (or sibling `creating-file-epics` skill) for authoring an Epic file from a plan/spec. + +Skills that stay the same: `documenting-the-repo`, all `superpowers:*` process skills, all orthogonal command skills (`verify`, `run`, `simplify`, `code-review`, `init`, `review`, `security-review`). + +## Error handling + +| Failure | File mode surface | +|---|---| +| Epic file missing on disk | `mm dispatch` exits non-zero with `Epic '' not found at `; daemon refuses to start the workflow | +| Epic file parse error (malformed marker) | Workflow refuses to dispatch; one `` block appended idempotently to the Epic file's conversation section so the operator sees the failure inline (no log-tailing needed) | +| Concurrent edit race | Write-temp + rename; re-stat source before rename; if mtime changed, re-read + re-merge + re-write (bounded 3 retries, then fail loudly) | +| Watcher misses an mtime tick | 120s polling cadence; worst-case 120s extra latency; symmetric with GitHub mode | +| Human deletes `` marker | Parser refuses to read; workflow won't dispatch; clear named-marker error | +| Human deletes PR-body `` marker | `findEpicPr` falls back to `pr:` field in Epic file's `` (stamped once at PR creation) | +| File permissions / disk full | Standard fs error propagation; surfaces as a step failure with the OS error | + +General rule: file-mode failures are **diagnosable from the Epic file itself**. Operators never need to read daemon logs to learn what went wrong. + +## Testing strategy + +Three layers. + +**Layer 1 — Unit tests for the new code.** Each new file gateway, the parser, the renderer, the round-trip property test. Pure-function tests, no daemon, no engine. Mirrors how `packages/state-issue/test/` is shaped today. ~400 lines of new test code. + +**Layer 2 — The parametrized parity test.** The load-bearing test: a single fixture runs the implementation workflow end-to-end with each gateway backend and asserts **the same workflow outcome** for the same input: + +```ts +// packages/dispatcher/test/epic-store/parity.test.ts +describe.each(["github", "file"])("workflow parity — %s mode", (mode) => { + test("dispatch → park → resume → continue closes the Epic identically", async () => { + const deps = mode === "github" + ? buildTestDepsWithGitHubGateways(/* stubbed gh */) + : buildTestDepsWithFileGateways(/* tmpdir + epic file */); + const id = await dispatch(deps, EPIC_REF); + await awaitParked(id); + await answerQuestion(deps, EPIC_REF, "approved"); + await awaitContinuation(id); + await awaitSettled(id); + expect(getWorkflow(db, id)?.state).toBe("completed"); + }); +}); +``` + +If the workflow ever takes a different path in the two modes for the same input, this catches it. Proves "no workflow code changes" on every commit. + +**Layer 3 — The existing test suite, unchanged.** Every workflow, gate, watchdog, hook-server, poller test keeps passing because the workflow bodies don't change.
