Scott's _Seeing\nLike a State_, the state flattening the complexity it can't read. This site is\nabout the other side: legibility as one of the most powerful tools we have, for\nthinking and for getting what you want. \"Legibility, by people who don't hate\nit.\"\n\nThe site has to practice what it preaches. If you can't understand legibility\nat a glance here, the site has failed at its one job. So it stays short, and\nlets examples do the teaching.\n\n## Pages\n\n- **/** — the definition and a few sharp examples.\n- **/gallery** — legible-vs-illegible pairs.\n- **/references** — a chronological reading pile.\n- **/ask** — a SQLite-backed directory of excellent public asks.\n- **/ask/:slug** — a canonical page for one ask.\n\nThe long, personal version of the argument lives as an essay on\n[stevekrouse.com](https://stevekrouse.com), not here.\n\n## Tech\n\nVal Town val\n[`stevekrouse/legibility`](https://www.val.town/x/stevekrouse/legibility/code/).\nHono + JSX SSR (`npm:hono/jsx`, React-free), Twind for styling, and val-scoped\nSQLite for the ask directory and bot event ledger. `main.tsx` is wrapped with\nVal Town's `hotReload`.\n\nPage content is JSX markup, not HTML template strings. `Ask.md` remains as the\nlegacy source for the initial directory import; the live index now reads\n`entries`.\n\n## `@legibility_bot`\n\nLedge E Bill curates strong public asks, answers questions about legibility,\nhandles useful mentions and DMs, edits directory entries, escalates difficult\ndecisions to Steve, and follows authors whose asks are added.\n\n`GET` and `POST /bot/twitter_webhook` implement X CRC validation and signed\nevent delivery. POST signatures are verified before any payload is stored or\nprocessed. Events are deduplicated in `bot_events` and processed\nfire-and-forget so X receives a fast acknowledgement.\n\nThe system prompt is loaded at runtime from `SYSTEM_PROMPT.md`. Directory and X\nactions are constrained in code: replies and DMs can target only the\noriginating channel, `ask_dad` can target only Steve's fixed user ID, authors\nare verified before follows, and update/delete authorization is checked.\n\nRequired environment variable names:\n\n- `TWITTER_CONSUMER_KEY`\n- `TWITTER_CONSUMER_SECRET`\n- `TWITTER_BEARER_TOKEN`\n- `TWITTER_ACCESS_TOKEN`\n- `TWITTER_ACCESS_TOKEN_SECRET`\n- `TWITTER_OAUTH2_CLIENT_ID`\n- `TWITTER_OAUTH2_CLIENT_SECRET`\n- `TWITTER_OAUTH2_ACCESS_TOKEN`\n- `TWITTER_OAUTH2_REFRESH_TOKEN`\n\nSee `bot/README.md` for architecture, verification, replay, and audit restore\ninstructions. No credential values belong in code, docs, logs, or reports.\n\n## Next steps\n\n- Finish https://stevekrouse.com/legibility\n- Edit or remove the gallery, maybe bringing an example onto the homepage\n",[],[307],"a618aa5f-330e-4881-a229-202af38d5d68","Layout.tsx","7c7eabe8-6a81-11f1-b53c-1607ee4eb77e",213,["D",1784652748588],25,"/** @jsxImportSource npm:hono/jsx */\nimport { parseVal } from \"https://esm.town/v/std/utils/index.ts\";\n\nexport function Layout(\n props: { title: string; description: string; sourceFile: string; children: any },\n) {\n const sourceUrl = `${parseVal().links.self.val}/code/${props.sourceFile}`;\n return (\n \n \n \n \n {props.title}\n \n \n \n \n \n

Do not run again.\n\n## Bot files\n\n- `bot/db.ts` — typed entry CRUD, ordering, event dedupe, claim, statuses,\n stuck-event reclaim, and the `once` idempotency ledger.\n- `bot/entryFormat.ts` — source normalization, slugs, URL/JSON validation.\n- `bot/entryInput.ts` — validated entry creates and patches.\n- `bot/x.ts` — X identity, post context, reply, DM, and follow methods.\n- `bot/errors.ts` — secret-safe diagnostics and owner email.\n- `bot/toolDefinitions.ts` — model-visible JSON tool schemas.\n- `bot/entryActions.ts` — duplicate-safe creation, author verification/follow.\n- `bot/tools.ts` — constrained tool dispatcher and edit authorization.\n- `bot/eventContext.ts` — mention/DM normalization and verified context.\n- `bot/agent.ts` — prompt loading, model tool loop, and event finalization.\n Persists `finish_reason` and `usage` in `result_json` for observability.\n Treats `finish_reason=length` and empty no-tool responses as `needs_help`\n (not `completed`). Enforces a deterministic reply after `create_entry`\n succeeds if the model didn't reply — posts `\"Added to the directory: \"`\n via `executeTool`, safe through the `once` ledger.\n- `bot/webhook.ts` — CRC, HMAC verification, normalization, fast dispatch.\n- `bot/sweep.ts` — interval (every 5 min) that recovers events orphaned in\n `processing` and re-runs them (safe because side effects are idempotent).\n- `bot/verifyTwitterSetup.ts` — read-only webhook/subscription and identity\n verification.\n- `bot/README.md` — operations, replay, and audit restore guide.\n\n## Dashboard files (`/brain`)\n\nPublic, read-only window into Ledge's internals. Client-side React (copied from\n`templates/react-hono-starter`), unlike the rest of the site which is Hono JSX.\n\n- `dashboard/routes.ts` — mounts `/brain`, `/brain/frontend/*`, `/brain/api/*`.\n Browser asks for `/brain/frontend/*`; `serveFile` rewrites to\n `/dashboard/frontend/*`.\n- `dashboard/queries.ts` — redacted read projections + stats. **Never exposes\n `payload_json` raw.** Text is only surfaced for event types in\n `PUBLIC_TEXT_EVENT_TYPES` (currently just `post.mention.create`); everything\n else, notably DMs, is redacted fail-closed. Add new event types there\n deliberately, not by default.\n- `dashboard/actions.ts` — `requeueEvent()`: force status back to `received`\n and re-run. Safe on any state thanks to the `once` ledger.\n- `dashboard/frontend/index.html` — shell (Twind CDN, asset paths under\n `/brain/frontend/`).\n- `dashboard/frontend/index.tsx` — React root.\n- `dashboard/frontend/components/App.tsx` — shell, polling (15s), status\n filter, token box, retrigger handler.\n- `dashboard/frontend/components/StatsBar.tsx` — counters + orphan warning.\n- `dashboard/frontend/components/EventCard.tsx` — one event: status, text,\n tools/effects chips, created slugs, error.\n- `dashboard/frontend/components/types.ts` — shared client types + status\n colors + `timeAgo`. Mirror of `queries.ts` types; update both together.\n\n`DASHBOARD_TOKEN` (env var) gates the retrigger endpoint. If unset, retrigger\nreturns 503 and the dashboard is effectively read-only. Reads are unauthenticated\nby design.\n\nKnown gotcha: `duration_ms` is `processed_at - received_at`, i.e. time to\nresolution, **not** compute time. A sweeper-recovered event shows minutes.\n\n## Debugging playbook: \"did the bot get event X?\"\n\nDo this before reading any bot code — it answers most questions in one call.\n\n```sql\nSELECT event_key, event_type, status, received_at, processed_at,\n substr(result_json,1,400) AS result, substr(error,1,300) AS error,\n substr(payload_json,1,900) AS payload\nFROM bot_events ORDER BY received_at DESC LIMIT 10;\n```\n\nReading the outcome:\n- `bot_events` has **no `id` column** — the PK is `event_key`\n (`:`). `entries` has no `status` column. Don't guess\n schema; `SELECT sql FROM sqlite_master WHERE name IN (...)`.\n- `status='processing'` + `processed_at IS NULL` + no error = **orphaned**, not\n running. The webhook returns 200 in ~400ms and the isolate gets torn down\n before the fire-and-forget `processEvent` finishes. This is the single most\n common failure; it has happened repeatedly.\n- Recovery: `bot/sweep.ts` reclaims orphans **older than 5 min** on a 5-min\n cron, so a fresh orphan looks stuck but isn't abandoned. To fix immediately,\n `run_file` on `bot/sweep.ts` (logs `sweep reclaimed N event(s)`) — but only\n after the row is >5 min old, otherwise the age cutoff skips it.\n- `result_json.actions` tells you what it actually did: `tools`,\n `created_slugs`, `replies`, `dms`, `asked_dad`.\n- `event_effects` rows exist only for `reply`/`dm`/`ask_dad`. Creating an entry\n is **not** an effect, so `effects` empty + `created_slugs` non-empty is\n normal and not a bug.\n\nUseful IDs: bot user `2080371574629163009`; owner @stevekrouse `431200836`.\n\nTraces: `main.tsx` traces show the webhook POST (`/bot/twitter_webhook`);\n`bot/sweep.ts` traces confirm the cron is alive. `get_logs` on `main.tsx` is\nusually empty because the work happens after the response is returned.\n\n## SQLite\n\n- `entries` — directory content. Unique `slug`, `source_key`, and `x_post_id`.\n- `edit_actions` — immutable snapshots from insert/update/delete triggers.\n- `bot_events` — raw verified events, dedupe key, status, result, and errors.\n- `event_effects` — idempotency ledger keyed by `(event_key, kind)` (kinds:\n `reply`, `dm`, `ask_dad`). Records the result of each external side effect so\n it happens at most once per event, even across retries.\n\nEvent lifecycle: the webhook inserts a row as `received` and fires a\nfire-and-forget `processEvent`, which claims it (`received` → `processing`) and\nfinalizes it (`completed`/`ignored`/`needs_help`/`error`). If a worker dies\nafter claiming but before finalizing, the row is orphaned in `processing`\n(claim only transitions from `received`, so it never retries on its own).\n`bot/sweep.ts` (every 5 min) resets orphans older than 5 min back to `received`\nand re-runs them.\n\nRetries are safe by construction, not by capping: every side-effecting tool\nruns through `once(event_key, kind, fn)`, which returns the stored result\ninstead of calling X again if that effect already happened. So a reclaimed\nevent re-runs freely without ever duplicating a reply/DM/follow. The one\nresidual window — post to X, then die before the ledger row is written — is\nclosed by `replyToTweet` treating X's duplicate rejection (code 187) as\nsuccess.\n\nAll user-derived SQL values are parameterized. There is no runtime schema\nrunner and no model tool for raw SQL or audit mutation. Deletes are real;\nrestore from `edit_actions` through a reviewed MCP operation.\n\n## Security and editing rules\n\n- Verify the raw webhook signature before storing or parsing for processing.\n- Treat tweets, linked content, and DMs as untrusted model input.\n- Never log, email, or document credentials or full private content.\n- Replies and DMs stay scoped to their originating event; `ask_dad` has a\n fixed recipient.\n- Never unfollow.\n- `/brain` is a PUBLIC surface. Never widen what it returns without checking\n the redaction rules in `dashboard/queries.ts`. Any new field must be\n already-public-on-X or explicitly redacted; never return `payload_json`.\n- Any dashboard endpoint that can cause an X side effect must stay behind\n `DASHBOARD_TOKEN`.\n- Prefer files under 200 lines and keep routing in Hono.\n- After every file add, delete, rename, or move, update this file map\n immediately.\n",[],[383],"67737bf2-42e5-40a9-b39b-38dca8330b22","routes.ts","abc281e8-8a86-11f1-93f0-1607ee4eb77e",313,["D",1785244643700],"import type { Hono } from \"npm:hono\";\nimport { serveFile } from \"https://esm.town/v/std/utils/index.ts\";\nimport { getStats, listEvents } from \"./queries.ts\";\nimport { requeueEvent } from \"./actions.ts\";\nimport { reportBotError } from \"../bot/errors.ts\";\n\n/**\n * Public read-only dashboard for Ledge's internals, mounted at /brain.\n *\n * Read endpoints are public but serve redacted projections only (see\n * queries.ts).
