Steps use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Every mistake a reviewer or test catches in an agent's work is kept with its fix, repeated mistakes become short approved rules, and the matching rules are handed to the next agent before it starts. + +**Architecture:** Three layers inside the knowledge-base server, all under `src/mistakes/`. An append-only JSONL ledger of mistake records (raw). Pattern notes in the vault, drafted by a model, gated by code and approved by the operator (wiki). A delivery function that returns at most 3 approved patterns for a task, plus delivery and run logs (use). MCP tools, `/api/v1` routes, the `kb` CLI and a dashboard panel sit on top. + +**Tech Stack:** Node.js 20+, ES modules, `node --test`, Express 4, better-sqlite3, gray-matter, zod. No new dependencies. + +**Spec:** `docs/superpowers/specs/2026-10-13-mistake-ledger-design.md` (approved by the operator on 2026-10-14). + +**Companion plan:** the agent-swarm side (known pitfalls at `swarm init`, capture when a fix passes review, the run metric) is `docs/plans/2026-10-14-swarm-mistakes.md` in the agent-swarm repository. It needs this plan's `/api/v1` routes and is built after it. + +**How this plan was checked:** every code block below was run as a prototype before the plan was written (112 new tests, plus the existing `tools`, `v1` and `api-key` tests, all passing). The importer was also run read-only against the two real review ledgers (57 and 8 findings parsed). + +## Global Constraints + +- Node 20 or later, ES modules, tests with `node --test` (`node:test` and `node:assert`). **No new dependencies:** `package.json` and `package-lock.json` do not change. +- Storage lives in `~/.knowledge-base/mistakes/` (`ledger.jsonl`, `deliveries.jsonl`, `runs.jsonl`, `approval-latest.json`). `KB_MISTAKES_HOME` overrides the folder. +- **Append-only:** no code path rewrites or deletes a line of `ledger.jsonl`, `deliveries.jsonl` or `runs.jsonl`. A correction is a new record that names the old one in `supersedes`. +- Patterns are vault notes at `patterns/.md`. The vault is `OBSIDIAN_VAULT_PATH`, else `~/knowledgebase`. +- Limits, copied from the spec: + - `fix_diff` is at most 4 KB, with secrets redacted by the patterns in `src/capture/terminal.js`; + - a pattern rule is at most 60 words; + - a draft needs mistakes from at least 2 different tasks; + - `kb_patterns_for` returns at most 3 patterns, approved and in the `teach` group only, and none below a minimum score; + - each approved pattern is assigned to `teach` or `test` (50/50) once, at approval, and never moved; + - an approved pattern delivered to no task for 90 days is flagged on the next approval page, and never removed automatically. +- `client_ok` must be `true` on every record. A record from a client job is only kept with the client's permission. +- **Tests never touch the real `~/.knowledge-base` or the real vault.** Every test sets `KB_MISTAKES_HOME` (and `OBSIDIAN_VAULT_PATH` where patterns are used) to a temp folder. A test that loads `src/db.js`, `src/ingest.js`, `src/auth.js`, anything in `src/routes/` or `src/cli/` sets `process.env.HOME` to a temp folder **before** it imports them, using `await import(...)`. +- Never read, print or search any `.env` file. Never put a real secret in a file in the repository. +- User-facing text (CLI output, error messages, the approval page, the dashboard) is plain English: it says what happened and what to do next. +- Commit with the messages given. Never `git add -A`. +- **Out of scope:** fine-tuning; changing any reviewer; phase 2 (the replay proof and capturing operator corrections); `openapi.json` (it is the public ChatGPT-actions surface and stays as it is). + +## Decisions made while planning + +The spec leaves these open. Each is the smallest choice that keeps the spec's intent. + +1. **A fourth pattern status, `rejected`.** The spec's reply format has "reject 4" but lists only draft, approved and retired. A rejected draft is kept so its mistakes are not proposed again. +2. **"edit 2: " approves the pattern with the operator's wording.** +3. **Two extra record fields.** `evidence` (`strong` with a fix commit, else `weak`; the spec asks for the weak mark) and `key` (a stable key that makes imports safe to repeat). +4. **Which mistakes a pattern covers is stored in the pattern note** (`evidence`), because ledger records are never edited. +5. **The KB copy of a record is a database document** (`doc_type: mistake`, made with `ingestText`), not a vault note. The ledger file stays the source of truth; a failed copy is reported, never fatal. +6. **Bad input and server faults are told apart.** Store functions throw `InputError` for input the caller can correct; the routes answer 400 for those and 500 for anything else. +7. **`test`-group patterns are never flagged as unused.** They are never delivered by design. +8. **The seed catalogue has no diffs.** Its "Fix:" text is the good example when a draft is built only from seed records. +9. **Backfill sources.** CareOps kept no review ledger, so the backfill covers the agent-swarm and Factory ledgers, the live-demo swarm run and the seed catalogue. +10. **Scoring is plain word overlap** (tag words count 2, name and rule words count 1, minimum 3). Patterns number in the tens, so no search index is needed. + +## Review Focus + +Failure cases the spec implies but does not name. Each has a test in the task that owns the code. + +1. **A ledger line cut off by a crash.** Reads skip it and count it; the next record starts on its own line. (Task 1: "skips a line cut off by a crash…") +2. **Several processes appending at once** (the server and the CLI). Every record stays one intact line. (Task 1: "keeps every record on its own line when several processes append at once") +3. **A secret that straddles the 4 KB cut of `fix_diff`.** Redaction runs before truncation, so no fragment survives. (Task 1: "redacts before it truncates…") +4. **A pattern note edited by hand into something unreadable** (broken frontmatter, a rule over 60 words, a renamed file). It is skipped with a reason; listing, delivery and the approval page keep working. (Task 2: "skips a hand-edited note that is broken…"; Task 4: "still answers when a pattern note is broken"; Task 7: "lists notes it could not read") +5. **A reply that is partly wrong** ("approve 1, approve 9").

Pattern approvals

+
How to reply. Use the numbers below, for example:
approve 1 and 3, edit 2: <your wording of the rule>, reject 4${stale.length ? `, retire ${drafts.length + 1}` : ''} +

Approve: agents may be given this rule. Edit: approve it with your wording (at most ${MAX_RULE_WORDS} words). Reject: never propose it again from these mistakes. Anything you leave out stays as it is. Half of the approved patterns are held back from agents, so a later test can measure whether patterns help.

    How to reply. Use the numbers below, for example:
    approve 1 and 3, edit 2: <your wording of the rule>, reject 4${stale.length ? `, retire ${drafts.length + 1}` : ''} +

    Approve: agents may be given this rule. Edit: approve it with your wording (at most ${MAX_RULE_WORDS} words). Reject: never propose it again from these mistakes. Anything you leave out stays as it is. Half of the approved patterns are held back from agents, so a later test can measure whether patterns help.
