A\nsidebar holds an Assignees section with an assign-yourself shortcut and a Labels\npicker over the curated set. The footer has Create, Cancel, and a Create more\ncheckbox that returns to a fresh create form after submitting instead of the new\nissue. Submitting without a title re-renders the form with an error and\npreserves the entered input. The edit page mirrors this layout with title and\nbody only. Assignee handles remain unvalidated, and the form notes this.\n\n**Blocked by:** 01\n\n**Status:** ready-for-agent\n\n- [ ] Create shows a required title, a description editor with a Write tab and\n an inert Preview slot, and a sidebar with Assignees (incl.\n assign-yourself) and a label picker\n- [ ] Submitting with a title creates the issue with the chosen labels and\n assignees\n- [ ] Submitting without a title re-renders the form with an error and the\n previously entered body/metadata preserved\n- [ ] The Create more checkbox redirects back to a fresh create form instead of\n the new issue\n- [ ] Edit mirrors the layout with title + body and saves via the existing route\n- [ ] No route, store, API, or schema

Successful responses are either a single object, an\narray, or a small acknowledgement object (`{\"deleted\": id}` /\n`{\"updated\": id}`); error responses always have the shape:\n\n```json\n{ \"error\": \"human-readable message\" }\n```\n\n### Label\n\n```ts\n{\n id: number;\n name: string;\n color: string; // six lowercase hex characters, no leading \"#\"\n created_at: number; // ms since epoch\n updated_at: number;\n}\n```\n\n### IssueReference\n\nThe compact shape used inside `blockers` and `blocks`.\n\n```ts\n{\n id: number;\n title: string;\n status: \"open\" | \"closed\";\n state_reason: \"completed\" | \"not_planned\" | \"duplicate\" | \"reopened\" | null;\n}\n```\n\n### Issue\n\n```ts\n{\n id: number;\n title: string;\n body: string; // markdown, verbatim (not trimmed)\n status: \"open\" | \"closed\";\n state_reason: \"completed\" | \"not_planned\" | \"duplicate\" | \"reopened\" | null;\n created_at: number;\n updated_at: number; // last activity: own edits, comments, or association changes\n creator: string | null; // Val Town handle, derived from the issue's creation event\n labels: Label[];\n assignees: string[]; // Val Town handles, no \"@\" prefix\n blockers: IssueReference[];\n blocks: IssueReference[];\n blocked: boolean; // true iff at least one blocker is still \"open\"\n}\n```\n\n`GET /api/issues/:id` returns an `Issue` plus a `comments` field\n(`comments: Comment[]`); no other endpoint includes `comments`.\n\n### Comment\n\n```ts\n{\n id: number;\n issue_id: number;\n body: string; // markdown, verbatim\n created_at: number;\n updated_at: number;\n author: string | null; // Val Town handle, derived from the comment's creation event\n}\n```\n\n### Event\n\n```ts\n{\n id: number;\n event_type:\n | \"issue.created\" | \"issue.updated\" | \"issue.deleted\"\n | \"comment.created\" | \"comment.updated\" | \"comment.deleted\"\n | \"label.created\" | \"label.updated\" | \"label.deleted\";\n entity_id: number; // the issue/comment/label id the event is about\n actor: string;\n data: unknown; // grammar below\n event_timestamp: number;\n}\n```\n\n`GET /api/issues/:id/events` returns `Event[]` in append order.\n\n## Event data grammar\n\nEvents are the source of truth for provenance and history; live tables hold only\ncurrent state.\n\n- **Boundary events (`*.created`, `*.deleted`) snapshot full state.** The `data`\n field is the entity's complete state at that moment — a hard-deleted row\n leaves a full tombstone:\n - `issue.created` / `issue.deleted` data:\n `{id, title, body, status, state_reason, created_at, updated_at}`\n - `comment.created` / `comment.deleted` data:\n `{id, issue_id, body, created_at, updated_at}` (no `author` — that is always\n derived from the surrounding event, never stored in the payload)\n - `label.created` / `label.deleted` data:\n `{id, name, color, created_at, updated_at}`\n- **`*.updated` events carry a single field delta:**\n `{update_target, from, to}`.\n - For `issue.updated`, `update_target` is one of `title`, `body`, `status`,\n `state_reason`, `label`, `assignee`, `blocks`, `blocked_by`. Associations\n (`label`, `assignee`, `blocks`, `blocked_by`) use **`null ↔ value`**\n (`from: null` = added, `to: null` = removed). A block edge writes exactly\n one event, on the acting issue (the one named in the endpoint path).\n - For `comment.updated`, `update_target` is `\"body\"`.\n - For `label.updated`, `update_target` is `\"name\"` or `\"color\"`.\n - One event per changed field: closing an issue with a new reason emits two\n `issue.updated` events (`status` and `state_reason`), sharing one actor and\n timestamp.\n\n## Status codes\n\n| Status | Meaning |\n| ------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n| `200` | Read succeeded, or a mutation applied and the endpoint returns the resulting state. |\n| `201` | An issue, comment, or label was created. |\n| `400` | The request is malformed: invalid `:id`, invalid `status` filter, invalid close `reason`, invalid label `color`, a missing required scalar field (`title`; `name`/`color`; comment `body`), or a collection field (`label_ids`, `add`, `remove`, `assignees`) that isn't shaped as required — see below. |\n| `401` | A write was attempted with a missing or incorrect bearer token. |\n| `403` | A write was attempted but `ISSUE_TRACKER_API_KEY` isn't configured, so writes are disabled entirely. |\n| `404` | The issue, comment, or label named by `:id` — or referenced by an ID inside `label_ids`/`add`/`remove` — does not exist. |\n| `409` | The write conflicts with an existing invariant: a blocking edge would create a cycle (including a self-edge), or a label `name` collides with an existing label. |\n\n## Strict collection validation\n\n`label_ids`, and the `add`/`remove` fields on the labels and blocks/blocked-by\nendpoints, are validated as a whole, not filtered element by element:\n\n- **Absent** — treated as an empty operation (no IDs added or removed).\n- **Present** — must be an array where every element is a positive integer\n (`Number.isInteger(x) && x > 0`). Any other shape (not an array, a\n non-integer, zero, a negative number, a string, etc.) rejects the entire\n request with `400`; nothing is applied.\n- Each ID that passes shape validation must still reference an existing label or\n issue, or the request fails with `404`.\n\n`assignees`, and the `add`/`remove` fields on the assignees endpoint, follow the\nsame absent-is-empty / present-is-all-or-nothing rule, but for handles:\n\n- **Present** — must be an array of non-empty strings after trimming and\n stripping a leading `@`. Any other shape rejects the request with `400`.\n- Handles are not entities (no lookup table), so there is no `404` for an\n unrecognized assignee — any well-shaped handle is accepted.\n\n## Endpoints\n\n| Method and path | Body / query | Success |\n| --------------------------------- | -------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------ |\n| `GET /api/issues` | `?status=open\\|closed&label=&assignee=&search=` | `200` `Issue[]`. `400` if `status` is present and not `open`/`closed`. |\n| `POST /api/issues` | `{title, body?, label_ids?: number[], assignees?: string[], actor?}` | `201` `Issue`. `400` missing `title` or malformed `label_ids`/`assignees`. `404` if a `label_ids` entry doesn't exist. |\n| `GET /api/issues/:id` | — | `200` `Issue & {comments: Comment[]}`. `400` invalid id. `404` missing issue. |\n| `PATCH /api/issues/:id` | `{title?, body?, actor?}` | `200` updated `Issue`. `400` invalid id. `404` missing issue. |\n| `DELETE /api/issues/:id` | `{actor?}` | `200` `{deleted: id}`. `400` invalid id. `404` missing issue. |\n| `POST /api/issues/:id/close` | `{reason?: \"completed\" \\| \"not_planned\" \\| \"duplicate\", comment?, actor?}` | `200` updated `Issue`; reason defaults to `completed`. `400` invalid id/reason. `404` missing issue. |\n| `POST /api/issues/:id/reopen` | `{actor?}` | `200` updated `Issue` with `state_reason: \"reopened\"`. `400` invalid id. `404` missing issue. |\n| `POST /api/issues/:id/labels` | `{add?: number[], remove?: number[], actor?}` | `200` updated `Issue`. `400` invalid id or malformed `add`/`remove`. `404` missing issue or a missing label id. |\n| `POST /api/issues/:id/assignees` | `{add?: string[], remove?: string[], actor?}` | `200` updated `Issue`. `400` invalid id or malformed `add`/`remove`. `404` missing issue. |\n| `POST /api/issues/:id/blocks` | `{add?: number[], remove?: number[], actor?}` | `200` updated `Issue`. `400` invalid id or malformed `add`/`remove`. `404` missing issue or referenced issue id. `409` cycle or self-edge. |\n| `POST /api/issues/:id/blocked-by` | `{add?: number[], remove?: number[], actor?}` | Same as `/blocks`, opposite edge direction. |\n| `POST /api/issues/:id/comments` | `{body, actor?}` | `201` `Comment`. `400` invalid id or missing `body`. `404` missing issue. |\n| `PATCH /api/comments/:id` | `{body, actor?}` | `200` `{updated: id}`. `400` invalid id or missing `body`. `404` missing comment. |\n| `DELETE /api/comments/:id` | `{actor?}` | `200` `{deleted: id}`. `400` invalid id. `404` missing comment. |\n| `GET /api/issues/:id/events` | — | `200` `Event[]` in append order. `400` invalid id. `404` missing issue. |\n| `GET /api/labels` | — | `200` `Label[]`. |\n| `POST /api/labels` | `{name, color, actor?}` | `201` `Label` (`color` is hex, with or without `#`). `400` missing `name`/`color` or invalid `color`. `409` `name` already in use. |\n| `PATCH /api/labels/:id` | `{name?, color?, actor?}` | `200` updated `Label`. `400` invalid id or `color`. `404` missing label. `409` renaming to an in-use `name`. |\n| `DELETE /api/labels/:id` | `{actor?}` | `200` `{deleted: id}`. `400` invalid id. `404` missing label. |\n\nAll write routes additionally return `401` for a missing/incorrect bearer token,\nand `403` if `ISSUE_TRACKER_API_KEY` is unset — checked before any body or id\nvalidation.\n\n## Triage labels\n\nLabels are curated entities, not free-text arrays. Before applying workflow\nlabels such as `needs-triage`, create each one once with `POST /api/labels`,\nretain its ID, then send that ID to the issue-label endpoint.

Governed by `CONTEXT.md` + ADRs\n0001–0004.\n\nAll tickets are `ready-for-agent` — agent-grabbable by construction.\n\n## Implementation checklist\n\n- [x] Ticket 1 — core schema reshape and issue lifecycle\n- [x] Ticket 2 — append-only events and lifecycle provenance\n- [x] Ticket 3 — labels, assignees, blocking, comments, events, and touch rules\n- [x] Ticket 4 — idempotent old-schema migration\n- [x] Ticket 5 — final JSON API convention, consumer cleanup, and verification\n\nWork the **frontier**: any ticket whose blockers are all done. Order here is\ndependency order (blockers first): 1 → 2 → 3 → then 4 and 5 in parallel.\n\n> Migration caveat: tickets 1–3 are correct against _fresh_ databases. The ~3\n> existing deployments are only safe to run once ticket 4 (migration) lands,\n> since `initSchema` runs against live data every request. Deploy the set at the\n> end.\n\n## 1. Core schema reshape + issue lifecycle\n\nStatus: ready-for-agent\n\n**What to build:** Fresh-install issue schema on the new model — priority\nremoved entirely; `status` collapses to `open`/`closed`; a nullable\n`state_reason` (`completed`/`not_planned`/`duplicate`/`reopened`) guarded by a\n`CHECK` constraint against status; the issue body field renamed from\n`description` to `body`. The create / close / reopen operations auto-manage\n`state_reason` (create → null; close → chosen reason, default `completed`;\nreopen → `reopened`). The JSON API and HTML UI are reconciled to the new `Issue`\nshape, and the schema knowledge those two consumers currently duplicate\n(status/priority constants, label parse/serialize) is pulled into the\ndata-access layer as a prefactor so later tickets change one place. No migration\nof existing data in this ticket. _Demoable: create an issue, close it as\nnot_planned, reopen it — through both the API and the UI._\n\n**Blocked by:** None — can start immediately.\n\n## 2. Events log foundation + issue lifecycle events\n\nStatus: ready-for-agent\n\n**What to build:** The single append-only events table (`id`, `event_type`,\n`entity_id`, `actor`, `data`, `event_timestamp`) and the emit helper, wired into\nthe issue lifecycle from ticket 1. `*.created` and `*.deleted` carry full state\nsnapshots; `*.updated` carries `{ update_target, from, to }`. One event per\nchanged field, so closing emits two events (`status` and `state_reason`) sharing\nan actor and timestamp. _Demoable: close an issue and observe two events with\nthe acting handle and correct payloads._\n\n**Blocked by:** 1\n\n## 3. Associations: labels + assignees + blocking\n\nStatus: ready-for-agent\n\n**What to build:** All three issue relationships, end-to-end (schema +\noperations + API\n\n- UI + events + touch rule):\n\n* **Labels** — a curated Label entity (`name`, `color`), applied via a bare\n issue↔label join; a default set (`bug`, `enhancement`, `documentation`,\n `question`, `duplicate`) seeded exactly once at table creation and never\n re-seeded; apply/remove; label rename/recolour/delete (deleting an in-use\n label cascades its join rows away).\n* **Assignees** — a set of Val Town users via a bare issue↔handle join;\n add/remove; an \"assigned to me\" query.\n* **Blocking** — a directed `blocker → blocked` edge stored once; insert\n rejected if the target can already reach the source (strict DAG — self,\n reciprocal, and longer cycles all refused); remove; \"blocked\" derived (blocked\n while any blocker is still open) and never stored, and never gating close.\n\nEvery mutation emits its events — label ops as `label.*` plus `issue.updated`\nwith `update_target: label` using `null ↔ value`; assignee and block changes as\n`issue.updated` with `update_target` ∈ {assignee, blocks, blocked_by},\n`null ↔ value`; a block edge writes one event on the acting issue. Every\nassociation change also touches the parent issue's `updated_at`.\n\n_(Largest ticket — if it overflows a single context window at execution time,\nsplit back into labels / assignees / blocking, each blocked by 1 and 2.)_\n\n**Blocked by:** 1, 2\n\n## 4. Migration for existing deployments\n\nStatus: ready-for-agent\n\n**What to build:** One idempotent migration routine (living in the schema-init\npath, safe to run every request) that brings the ~3 existing deployments onto\nthe final schema: remap any `in_progress` issue to `open`; drop priority; expose\nthe old `description` as `body`; lift each existing JSON `labels` array into the\nLabel entities and issue↔label join (creating labels as needed); move any\nexisting single `assignee` into the assignee join; and backfill a synthetic\n`*.created` event (and any required state) for existing rows so no entity is\nleft without provenance. Running it twice is a no-op.\n\n**Blocked by:** 1, 2, 3\n\n## 5. Rewrite JSON API convention doc + final cleanup\n\nStatus: ready-for-agent\n\n**What to build:** Rewrite `docs/issue-tracker-valtown.md` to the new schema and\nendpoint surface (no priority, two statuses, `state_reason` on close/reopen, and\nthe label / assignee / block operations), replacing the outdated convention it\ndocuments today. Remove any remaining old-schema constants or dead code paths in\nthe consumers. Done last so the doc describes the final API exactly once.\n\n**Blocked by:** 3\n",[],[304,505,506,497],"issues","richer-data-model","1da2fc19-c168-4db0-ace9-4a383b4d3b42","certification.md","1d471d5a-7c96-11f1-a281-1607ee4eb77e",195,["D",1783711960231],"# Certification: richer-data-model remediation pass\n\nDate: 2026-07-10 Verdict: **certified complete** (independent recertification\naudit)\n\nAfter the five implementation tickets in `tickets.md` landed, a remediation pass\nran as five one-shot agent prompts (formerly in `agent-prompts/`, deleted after\nthis certification). What each fixed:\n\n1. **SQLite transaction contract** — `db.ts` drives every multi-statement write\n through `client.transaction(\"write\")` with explicit commit/rollback, never\n top-level `batch()`. The resolved adapter\n (`npm:@tursodatabase/serverless@1.2.3/compat`) was read at source and its\n top-level `batch()` confirmed broken for this purpose: it ignores the mode\n argument and drops bound args. Proven by tests: a batch-throwing client,\n forced mid-transaction failure rollback, and entity-ID (not event-ID) return\n values.\n2. **Comment UI** — the comment edit control is a `

` that round-trips\n   multiline markdown through the real Hono form routes; bodies render as\n   escaped JSX text with `whitespace-pre-wrap` (no HTML rendering). Control\n   visibility fixed via a maintainer-only `canModerateComments` prop on\n   `IssueDetailPage`: maintainers and the comment author see edit/delete\n   controls; a non-author issue creator does not. Server-side checks remain the\n   enforcement layer and the UI mirrors them exactly.\n3. **API/docs parity** — strict all-or-nothing validation for collection fields\n   (`label_ids`/`add`/`remove`/`assignees`: absent = empty operation,\n   present-but-malformed = 400); 400 for an invalid `status` filter; 404\n   existence guards on every mutation route; a small typed `HttpError`\n   (400/404/409) in `db.ts` replacing the old map-everything-to-409 handler;\n   `docs/issue-tracker-valtown.md` rewritten with complete response shapes, the\n   event-data grammar, the `{\"error\": \"...\"}` convention, a status-code table,\n   and exact per-route responses matching `api.ts` route-by-route.\n4. **Check policy** — Biome (tab-indented) is the canonical formatter, not\n   `deno fmt`; `.vt/` and `.claude/` excluded via `biome.json` `files.includes`;\n   canonical commands are the `deno.json` tasks `fmt` / `lint` / `typecheck` /\n   `test` / `check` (aggregate), documented in `README.md` and all passing.\n5. **Recertification** — independent audit rebuilt the requirement matrix for\n   all five tickets against the PRD, re-ran all checks (21/21 tests), compared\n   every API route against the convention doc (18 route/status combinations),\n   and repeated the stale-schema scan: no live use of priority, `in_progress`,\n   `description`, JSON-label storage, single-assignee storage, `*_by` columns,\n   or a stored comment `author` column (`Comment.author` is derived from\n   `comment.created` events via JOIN, per ADR 0003/0004). The only old- schema\n   references are the migration reader in `db.ts` and legacy-fixture SQL in\n   `db_test.ts`, by design.\n\n## Caveats\n\n- Nothing was deployed. The adapter-contract proof is static (reading the\n  resolved dependency's source), not a live round-trip against Val Town's scoped\n  SQLite. Live proof requires deploying and exercising one transactional write.\n- Known cosmetic quirk, out of scope: the HTML app's `onError` in `app.tsx`\n  renders every thrown error as a banner with HTTP status 409, including 404\n  `HttpError`s from the store. HTML routes check existence before mutating, so\n  it rarely triggers.\n",[],[304,505,506,508],"85c72af1-cc92-4979-a7a5-bac2e38e7689","PRD.md","eebd1596-7bf2-11f1-ab8e-1607ee4eb77e",174,["D",1783653142818],"# Spec: Richer data model for val-issue-tracker\n\nStatus: ready-for-agent\n\n> Synthesised from a grilling + domain-modeling session. Vocabulary follows\n> `CONTEXT.md`; decisions are governed by ADRs 0001–0004. This is a breaking\n> schema change to the tracker's own data model, plus the migration to get the\n> ~3 existing deployments onto it.\n\n## Problem Statement\n\nThe tracker's current data model carries fields the maintainer doesn't use and\ncan't represent the relationships they actually want. Priority is dead weight.\nStatus has a middle `in_progress` state that isn't wanted, yet there's no way to\nsay _why_ something was closed (done vs. abandoned). Labels are a JSON-array\nstring matched with `LIKE`, so they can't have colour, be renamed in one place,\nor be queried cleanly. There's no way to express that one issue blocks another.\nThere is no history: once a label is removed or an assignee dropped, the fact\nthat it was ever there is gone, and there's no record of who changed what. The\nmaintainer wants a GitHub-flavoured model that captures these relationships and\na full audit trail.\n\n## Solution\n\nReshape the tracker's schema to mirror GitHub's issue model where it earns its\nkeep, and add first-class structure for the things the maintainer actually uses:\n\n- Drop priority entirely and collapse status to `open` / `closed`, with a\n  nullable `state_reason` (`completed` / `not_planned` / `duplicate` /\n  `reopened`) carrying the nuance — so \"closed as done\" and \"closed as not\n  planned\" are distinguishable.\n- Promote labels from a JSON string to curated **Label** entities (name +\n  colour), applied to issues through a join, seeded with a small default set on\n  first install.\n- Make assignees a _set_ of Val Town users via a join, instead of a single\n  string.\n- Add directed **blocking relationships** between issues, kept as a strict DAG,\n  with \"blocked\" derived (an issue is blocked while any blocker is still open).\n- Record every change in a single append-only **events** log — the source of\n  truth for provenance (\"who did what, when\") and full state history, from which\n  auditability is derived. Live tables hold only current state.\n- Treat issue and comment bodies as markdown (a rendering contract; no storage\n  change).\n\nIdentity throughout is the Val Town handle — there is no local users table.\n\n## User Stories\n\n1. As a maintainer, I want priority removed from issues, so that the model\n   reflects that I never triage by priority.\n2. As a maintainer, I want status to be exactly `open` or `closed`, so that\n   there is no unwanted intermediate state to maintain.\n3. As a maintainer, I want to close an issue as `completed`, so that I can\n   record that the work was actually done.\n4. As a maintainer, I want to close an issue as `not_planned`, so that I can\n   record that I abandoned it rather than finished it.\n5. As a maintainer, I want to close an issue as `duplicate`, so that I can\n   record that it was already tracked elsewhere.\n6. As a maintainer, I want reopening an issue to mark its reason as `reopened`,\n   so that a reopened issue is distinguishable from one that was never closed.\n7. As a maintainer, I want the system to refuse an incoherent status/reason pair\n   (e.g. open + completed), so that the data can never represent an impossible\n   state.\n8. As a maintainer, I want `state_reason` to be set automatically by the\n   close/reopen/create actions, so that I can't forget to keep it consistent\n   with status.\n9. As a maintainer, I want labels to be real entities with names and colours, so\n   that I can see and manage a consistent taxonomy.\n10. As a maintainer, I want to apply an existing label to an issue by picking\n    it, so that typos can't spawn phantom labels.\n11. As a maintainer, I want to remove a label from an issue, so that the tag set\n    stays accurate.\n12. As a maintainer, I want a fresh install to come with a default set of labels\n    (`bug`, `enhancement`, `documentation`, `question`, `duplicate`), so that\n    the tracker is usable immediately.\n13. As a maintainer, I want labels I delete to stay deleted across restarts, so\n    that the default set doesn't resurrect itself on the next request.\n14. As a maintainer, I want to delete a label that is currently applied to\n    issues, so that retiring a tag just removes it everywhere.\n15. As a maintainer, I want to rename or recolour a label in one place, so that\n    every issue carrying it updates at once.\n16. As a maintainer, I want an issue to have zero or more assignees, so that\n    more than one Val Town user can own it.\n17. As a maintainer, I want to add and remove assignees on an issue, so that\n    ownership can change over time.\n18. As a maintainer, I want to ask \"what is assigned to me?\", so that I can find\n    my work without scanning every issue.\n19. As a maintainer, I want to declare that one issue blocks another, so that I\n    can express dependencies.\n20. As a maintainer, I want to view an issue's blockers and the issues it\n    blocks, so that I understand its dependency context from either direction.\n21. As a maintainer, I want an issue to show as blocked while any of its\n    blockers is still open, so that blocked-ness is always accurate without my\n    maintaining a flag.\n22. As a maintainer, I want closing a blocker to automatically unblock its\n    dependents, so that the state stays correct for free.\n23. As a maintainer, I want to still be able to close a blocked issue, so that\n    being blocked is informational and never traps me.\n24. As a maintainer, I want the system to reject an issue blocking itself, so\n    that nonsensical edges can't exist.\n25. As a maintainer, I want the system to reject any edge that would create a\n    cycle (direct or longer), so that the dependency graph stays a coherent DAG.\n26. As a maintainer, I want to remove a blocking relationship, so that I can\n    correct a dependency I no longer want.\n27. As a maintainer, I want issue and comment bodies treated as markdown, so\n    that formatting is preserved for later rendering.\n28. As a maintainer, I want to edit an issue's title and body, so that I can\n    correct or refine it after creation.\n29. As a maintainer, I want to edit a comment, so that I can fix mistakes in my\n    notes.\n30. As a maintainer, I want to delete a comment, so that I can remove notes that\n    no longer belong.\n31. As an auditor, I want every create, update, and delete recorded as an event\n    with the actor and timestamp, so that I can reconstruct who changed what and\n    when.\n32. As an auditor, I want each field change recorded with its before and after\n    value, so that I can see the full history of an issue's state.\n33. As an auditor, I want label applications, assignments, and block edges\n    recorded as events, so that removals are visible even though the\n    current-state row is gone.\n34. As an auditor, I want a deleted entity's final state captured in its\n    deletion event, so that a hard delete still leaves a complete record of what\n    was lost.\n35. As an auditor, I want a created entity's initial state captured in its\n    creation event, so that history can be replayed forward from a\n    self-contained starting point.\n36. As an auditor, I want to reconstruct an entity's state at any past point, so\n    that I can answer \"what did this look like last week?\".\n37. As a host-val developer, I want the tracker to keep using prefixed table\n    names in my scoped database, so that it never collides with my own tables.\n38. As a host-val developer, I want a friendly sequential issue number, so that\n    I can refer to issues as `#N` without an extra opaque id.\n39. As an existing deployment owner, I want my current issues migrated onto the\n    new schema, so that I lose no data when upgrading.\n40. As an existing deployment owner, I want any `in_progress` issue moved to\n    `open` during migration, so that no issue is stranded in a removed state.\n41. As an existing deployment owner, I want my current JSON labels lifted into\n    the new label and join tables, so that existing tags survive the change.\n42. As an existing deployment owner, I want existing rows to get a synthetic\n    creation event on migration, so that no entity is left with no provenance.\n43. As an agent, I want the JSON API to reflect the new schema (no priority, two\n    statuses, `state_reason`, label/assignee/block operations), so that\n    non-interactive callers drive the new model correctly.\n44. As an agent, I want the API convention doc updated to the new schema, so\n    that I'm not working from the outdated contract.\n45. As a maintainer, I want any change to an issue's labels, assignees, blocks,\n    or comments to bump the issue's `updated_at`, so that \"last activity\"\n    sorting reflects all activity, not just edits to the issue's own fields.\n\n## Implementation Decisions\n\n**Modules.** The single seam of change is the data-access layer (`db.ts`):\ntypes, schema creation/migration, and all query functions. The Hono JSON API and\nthe HTML UI are consumers that will be updated to match — both currently\nduplicate schema knowledge (status/priority constants, label parse/serialize)\nthat must be reconciled to the new model. The library's public entry point and\ntable-prefixing convention are unchanged.\n\n**Removed fields.** Priority is removed entirely (column, type, filters,\ncreate/update paths) — faithful to GitHub, which has no first-class priority.\nThe `in_progress` status is removed.\n\n**Status + state_reason.** `status` is `open` | `closed`. A nullable\n`state_reason` holds `completed` / `not_planned` / `duplicate` (with `closed`)\nor `reopened` (with `open`), or `null`. It is auto-managed: create → `null`;\nclose → chosen reason (`completed` default); reopen → `reopened`. A `CHECK`\nconstraint enforces the valid pairings so an incoherent row is impossible. (ADR\ncontext: mirrors GitHub; \"not planned\" is not a third state.)\n\n**Body.** The issue's `description` is renamed to `body` so Issue and Comment\nshare one term, matching GitHub. Bodies remain `TEXT`; markdown is a rendering\ncontract, not a storage change.\n\n**Labels (ADR 0001).** A **Label** is a curated entity: `id`, unique `name`,\n`color`. Applied via an issue↔label join (bare tuple), cascade-deleting both\nsides; deleting an in-use label is allowed and simply removes the join rows. A\ndefault set (`bug`, `enhancement`, `documentation`, `question`, `duplicate`) is\nseeded **exactly once, at the moment the labels table is first created**, never\nre-seeded — so user deletions survive. Labels are editable (rename/recolour in\none place).\n\n**Assignees.** Multi-valued set of Val Town users, stored as a bare\nissue↔user-handle join tuple. No local users table; identity is the handle.\nSupports \"assigned to me\" queries in both directions.\n\n**Blocking (ADR 0002).** A directed edge `blocker → blocked`, stored once with a\nunique pair constraint and cascade on issue delete. \"Blocks\" and \"blocked by\"\nare the same edge read from opposite ends. The graph is a **strict DAG**: on\ninsert, reject if the target can already reach the source (reachability check\nvia recursive query), which covers self-edges, direct reciprocals, and longer\ncycles alike — deliberately stricter than GitHub. \"Blocked\" is **derived, never\nstored**: an issue is blocked iff any blocker is still `open`; blocked-ness is\ninformational and does not prevent closing.\n\n**Audit + provenance (ADR 0003 as amended, ADR 0004).** Entities (Issue,\nComment, Label) keep only `created_at` + `updated_at` columns (for hot-path\nlisting / \"last activity\" sorting). There are **no `*_by` columns anywhere**;\nactor/provenance lives solely in the events log. Link rows carry no audit\ncolumns. Every entity is editable, including comments (the old comment `author`\ncolumn is gone; the author is derived from the `comment.created` event).\n\n**Events log (ADR 0004).** One append-only, polymorphic table with roughly this\nshape:\n\n| column            | meaning                                                                                 |\n| ----------------- | --------------------------------------------------------------------------------------- |\n| `id`              | ordering key                                                                            |\n| `event_type`      | `<entity>.<verb>`, entity ∈ {issue, comment, label}, verb ∈ {created, updated, deleted} |\n| `entity_id`       | id of the affected entity                                                               |\n| `actor`           | Val Town handle that performed the change                                               |\n| `data`            | JSON payload (shape depends on verb)                                                    |\n| `event_timestamp` | when it happened                                                                        |\n\nGrammar — _boundary events snapshot, updates carry deltas_:\n\n- `*.created` → full initial-state snapshot.\n- `*.deleted` → full final-state snapshot (entities are hard-deleted; the event\n  is the tombstone — soft-delete was considered and rejected).\n- `*.updated` → `{ update_target, from, to }`.\n- Associations (label apply/remove, assign/unassign, block add/remove) are\n  modelled as `issue.updated` events with `update_target` ∈ {`label`,\n  `assignee`, `blocks`, `blocked_by`} and `from`/`to` using **`null ↔ value`**\n  (null→X = added, X→null = removed). No separate verb or link entity type.\n- One event per changed field: closing emits two events (`status` and\n  `state_reason`) sharing one actor and timestamp; a \"closed as not planned\"\n  timeline line is a read-time grouping by (actor, timestamp).\n- A block edge writes **one** event, on the acting issue; the reverse \"blocked\n  by\" view is derived by querying events whose `to` references the issue.\n\n**Identity / numbering.** Issues keep the autoincrement `id` as their friendly\n`#N` — no separate opaque id, since a single scoped database per host makes `id`\na clean per-tracker counter and there are no PRs competing for the sequence.\n\n**Touch rule.** Mutating an issue's labels, assignees, block edges, or comments\nbumps that issue's `updated_at` (in addition to emitting an event).\n\n**Migration.** This is a breaking change against ~3 existing deployments (this\nval + two test vals). Migration must: rename `description` → `body`; drop\n`priority`; remap any `in_progress` issue to `open`; lift each existing JSON\n`labels` array into the new label entities (creating labels as needed) and\nissue↔label join rows; move any existing single `assignee` into the assignee\njoin; and backfill a synthetic `*.created` event (and any needed state) for\nexisting rows so nothing is left provenance-less. Migration runs within the\nexisting idempotent schema-init path and must be safe to run repeatedly.\n\n**API + docs.** The JSON API is updated to the new model: no `priority`, two\nstatuses, `state_reason` on close/reopen, and label / assignee / block\noperations. The convention doc `docs/issue-tracker-valtown.md` is rewritten to\nthe new schema (it currently documents the old one) as part of this work.\n\n## Testing Decisions\n\n**Seam.** A single new seam: the exported functions of the data-access layer\n(`db.ts`). There is no existing test suite, so this is the first — no prior art\nto mirror; establish the pattern here. Tests run against a scoped SQLite\ndatabase and exercise the exported functions directly, with no HTTP or UI in the\nloop.\n\n**What makes a good test here.** Assert _external behaviour_ of the data layer —\nthe observable outcomes of calling its functions — not internal implementation\n(not specific SQL, indexes, or private helpers). A good test states a domain\nrule and checks it holds.\n\n**Behaviours to cover:**\n\n- Status/reason: create leaves reason null; each close reason sets status closed\n  with the right reason; reopen sets `reopened`; the `CHECK` constraint rejects\n  an incoherent pair.\n- Labels: default set seeded on first creation; deletions survive a re-init\n  (seed-once); applying/removing labels; deleting an in-use label removes its\n  join rows.\n- Assignees: add/remove; \"assigned to me\" returns the right issues.\n- Blocking: self-edge rejected; direct reciprocal rejected; longer cycle\n  rejected; a valid edge accepted; \"blocked\" derived from open blockers; closing\n  a blocker unblocks dependents; a blocked issue can still be closed.\n- Events: create/update/delete emit events with correct type, actor, and payload\n  grammar (created/deleted snapshots, update deltas, association `null ↔ value`,\n  one-event-per- field on close, single event on block add); deleted-entity\n  snapshot is complete.\n- Touch: association and comment changes bump the parent issue's `updated_at`.\n- Migration: from a seeded old-schema database, `in_progress` → `open`, JSON\n  labels lifted into tables, `description` readable as `body`, and existing rows\n  gain creation events; running migration twice is a no-op.\n\n## Out of Scope\n\n- Rendering markdown to HTML, and rendering the events log as a UI activity\n  timeline (data supports both; presentation is deferred — see\n  `docs/backlog.md`).\n- Turning user handles into clickable profile links (backlog).\n- Reintroducing priority or an `in_progress` state in any form.\n- A local users table or any identity beyond the Val Town handle.\n- Soft delete / restore (explicitly rejected in favour of hard delete +\n  tombstone event).\n- Retention or pruning of the append-only events log.\n- Topological \"what should I work on next\" ordering (the strict DAG keeps the\n  door open for it later, but it is not built here).\n- Black-box tests at the HTTP/API layer (single `db.ts` seam only, by decision).\n\n## Further Notes\n\n- Governing decisions live in ADRs 0001–0004 and the glossary in `CONTEXT.md`;\n  use that vocabulary in issue titles, tests, and code.\n- Deferred wants are tracked in `docs/backlog.md`.\n- The stale `docs/issue-tracker-valtown.md` is intentionally left untouched\n  until this work rewrites it, so nothing points agents at the new schema before\n  it exists.\n",[],[304,505,506,516],"09a12ef3-b79f-45bc-b0d7-6c7e712da8e8","ee584d8c-7bf2-11f1-8d5b-1607ee4eb77e",138,["D",1783641873720],[339,340,341],[304,505,506],"03816fa8-dc6c-4678-be10-d32d70f490ee","b3ab7362-7fb7-11f1-8f98-1607ee4eb77e","b3107e7a-7fb7-11f1-b594-1607ee4eb77e",248,["D",1784056239133],"# PRD: GitHub-style UI refactor\n\nStatus: ready-for-agent\n\nWireframes for every screen live in `wireframes/` (browsable viewer at\n`wireframes/index.html`). They are the visual reference for this spec; the red\ndashed marks in them are annotations, not UI.\n\n## Problem Statement\n\nThe tracker's current UI is a functional but ad-hoc set of server-rendered\npages: the issue list is a dense table with no labels visible, filtering is a\nrow of separate form fields, issue management is a long single column of\nalways-visible forms stacked under the body, and label management looks nothing\nlike the rest of the app. For a user who lives in GitHub Issues, none of it\nmatches the mental model they already have, and the triage signal (labels like\n`ready-for-agent`) is invisible exactly where triage happens: the list.\n\n## Solution\n\nRestyle all pages after the GitHub Issues interface while keeping the existing\nroutes, role model, storage, and API untouched. A slim shared top bar (Issues ·\nLabels · current user) replaces per-page navigation. The issue list becomes a\ntoken search bar plus a panel of stacked rows with Open/Closed tabs, label\nchips, and a Blocked pill. The issue detail page becomes a two-column layout:\nthe body as the first comment card and the thread on the left, management\n(assignees, labels, relationships, delete) in a right sidebar of gear-revealed\nsections, with close-with-reason in the composer footer. Label management gains\na search input and an inline expanding create row. Issue creation gets a focused\ntitle + description column with metadata pickers in a sidebar. Everything stays\nserver-rendered and works without client-side JavaScript, using progressive\ndisclosure (`<details>`) and plain form posts.\n\n## User Stories\n\n1. As a user on any page, I want a consistent top bar with Issues and Labels\n   tabs and my handle/avatar, so that I always know where I am and can move\n   between the two surfaces in one click.\n2. As a visitor in standalone mode, I want the top bar to show a log in link\n   when I am signed out (and log out when signed in), so that the existing auth\n   affordances survive the redesign.\n3. As a user browsing issues, I want Open and Closed tabs with count pills at\n   the top of the list panel, so that I can switch lifecycle views and see\n   volumes at a glance.\n4. As a user browsing issues, I want each issue as a stacked row (state icon,\n   bold title, meta line, label chips), so that I can scan titles and triage\n   labels without opening anything.\n5. As a triager, I want label chips visible under each issue title in the list,\n   so that I can spot `ready-for-agent` vs `ready-for-human` work without\n   opening each issue.\n6. As a user browsing issues, I want a Blocked pill in a row's meta line when at\n   least one blocker is still open, so that I can skip work that cannot proceed.\n7. As a user browsing issues, I want each row's meta line to show number,\n   author, opened time, and last-updated time, so that I can judge freshness the\n   same way I do on GitHub.\n8. As a user browsing issues, I want rows sorted by last activity, so that the\n   most recently touched issues surface first.\n9. As a user browsing issues, I want a comment count on rows that have comments,\n   so that I can see where discussion is happening.\n10. As a user filtering issues, I want a single search bar that accepts\n    `status:` and `assignee:` tokens plus free text, so that one input replaces\n    the old row of separate filter fields.\n11. As a user filtering issues, I want free text in the search bar matched\n    against issue titles and bodies, so that I can find issues by content.\n12. As a contributor, I want a New issue button next to the search bar, so that\n    creating an issue is one click from the list.\n13. As a viewer (read-only role), I want the New issue button hidden, so that\n    the UI never offers actions I cannot perform.\n14. As a contributor creating an issue, I want a focused page with a required\n    title field and a description editor, so that writing is the primary\n    activity.\n15. As a contributor creating an issue, I want assignees and labels in a sidebar\n    with disclosure pickers over the curated label set, so that metadata never\n    interrupts the writing flow.\n16. As a contributor creating an issue, I want an \"assign yourself\" shortcut in\n    the Assignees section, so that self-assignment is one click.\n17. As a contributor creating an issue, I want a Create more checkbox that\n    returns me to a fresh form after submitting, so that I can enter several\n    issues in a row.\n18. As a contributor creating an issue, I want submitting without a title to\n    re-render the form with an error and my input preserved, so that I do not\n    lose work.\n19. As a user reading an issue, I want the title with the issue number, a filled\n    Open (or Closed) pill, and a Blocked pill when applicable, so that state is\n    legible at the top.\n20. As a user reading an issue, I want the body rendered as the first comment\n    card with author, opened time, an edited marker, and a role badge, so that\n    provenance reads like GitHub.\n21. As a user reading an issue, I want comments as cards with author and time,\n    so that the thread is easy to follow.\n22. As a user reading a closed issue, I want the close reason visible\n    (completed, not planned, duplicate), so that I know why it was closed.\n23. As a user reading a reopened issue, I want the reopened state visible, so\n    that I can distinguish it from a never-closed issue.\n24. As a commenter, I want a composer at the end of the thread with a Comment\n    button, so that replying is immediate.\n25. As a viewer, I want the composer replaced by a read-only notice, so that the\n    page degrades honestly for my role.\n26. As an issue manager (creator or maintainer), I want Close issue with a\n    reason chooser in the composer footer, so that closing with the right state\n    reason is part of the natural flow.\n27. As an issue manager, I want Reopen offered in the same spot when the issue\n    is closed, so that the lifecycle actions live in one place.\n28. As an issue manager, I want a sidebar with Assignees, Labels, and\n    Relationships sections that stay quiet until I open their controls, so that\n    reading is undisturbed by forms.\n29. As an issue manager, I want each sidebar section's controls revealed by a\n    disclosure (gear), so that add/remove actions are available without\n    permanent clutter.\n30. As an issue manager, I want to add and remove labels via a picker over the\n    curated set, so that labeling is choosing, never typing.\n31. As an issue manager, I want to add and remove assignees by Val Town handle,\n    so that responsibility stays visible.\n32. As an issue manager, I want the Relationships section to show both\n    directions (blocked by / blocks) with each blocker's open/closed state, so\n    that I understand the dependency picture.\n33. As an issue manager, I want adding a blocking edge that would create a cycle\n    to fail with a clear error, so that the DAG guarantee is surfaced, not\n    silent.\n34. As a comment author (or maintainer), I want edit and delete on my comments\n    via each card's overflow, so that moderation matches GitHub.\n35. As a maintainer, I want Delete issue in the sidebar clearly separated and\n    marked maintainer-only, so that the destructive action is hard to hit by\n    accident.\n36. As a user with no manage rights, I want the sidebar management controls\n    absent entirely, so that role boundaries render as absences, not errors.\n37. As an issue manager, I want a pencil next to the title leading to the edit\n    page, so that fixing a title or body is one click.\n38. As a user of the labels page, I want a search input over labels, so that I\n    can find a label as the set grows.\n39. As a user of the labels page, I want rows showing chip, hex color, and\n    open-issue count, so that I can see each label's look and usage.\n40. As a maintainer, I want New label to expand an inline create row (preview\n    chip, name, color with swatch), so that creation happens in place rather\n    than on another page.\n41. As a maintainer, I want edit and delete behind each label row's overflow\n    menu, so that management is available but not shouting.\n42. As a maintainer, I want the open-issue count visible before deleting a\n    label, so that the cascade (label vanishing from issues) is a visible\n    consequence.\n43. As a host-val owner mounting the tracker in routed mode, I want the compact\n    top bar to be the only chrome, so that the tracker embeds politely under my\n    router's own UI.\n44. As a keyboard or assistive-tech user, I want all interactions to be links,\n    forms, and native disclosures, so that the UI works without JavaScript and\n    with standard semantics.\n45. As a future user, I want a Preview tab slot in the editors that activates\n    when markdown rendering lands, so that the layout will not shift when the\n    roadmap catches up.\n46. As a triager, I want a `label:` search token (and a Labels dropdown that\n    injects it), so that I can narrow the list to a specific triage label like\n    `ready-for-agent`.\n47. As a user filtering issues, I want an `author:` search token (and an Author\n    dropdown), so that I can see issues opened by a given handle.\n48. As a user filtering issues, I want `is:blocked` / `is:unblocked` tokens (and\n    a Blocked/Unblocked dropdown), so that I can focus on work that can or\n    cannot proceed.\n49. As a user filtering issues, I want the Open/Closed tabs and every dropdown\n    to edit tokens in the one search query rather than replace it, so that\n    filters compose instead of clobbering each other.\n\n## Implementation Decisions\n\n- **No behavior-layer changes.** Routes, the store interface, the JSON API, the\n  database schema, and the role model (viewer / contributor / maintainer,\n  standalone vs routed, the auth-UI signal) all stay exactly as they are. This\n  is a presentation refactor of the page components and layout.\n- **Shared top bar in the layout component.** 64px bar rendered on every page:\n  Issues and Labels tabs with an active underline, current user handle and\n  avatar on the right, and the existing login/logout affordance when the auth UI\n  is enabled. All page-local back links and duplicate New issue buttons are\n  removed in favor of the bar.\n- **Zero-JS-first, progressive disclosure.** Every interaction must work as\n  plain links and form posts. Gear-revealed sidebar sections, the inline label\n  create row, overflow menus, and pickers are `<details>`/`<summary>`\n  disclosures. No client-side framework; if a sprinkle of JS is ever added it\n  must be an enhancement, not a requirement.\n- **Token search, parsed server-side.** The list's single search input submits\n  one query parameter. The server parses `status:<open|closed>`,\n  `assignee:<handle>`, `label:<name>`, `author:<handle>`, and\n  `is:blocked`/`is:unblocked` tokens out of it, in any order. `status` and\n  `assignee` feed the existing list-issues filters; `label`, `author`, and\n  blocked-ness are applied in-route over the returned issues (no store-interface\n  change — `blocked` stays a derived property). The remainder, and any\n  unrecognized token, become the free-text search. Old\n  `status`/`assignee`/`search` query parameters keep working.\n- **Token-injecting filter dropdowns.** The list header carries Author, Labels,\n  and Blocked/Unblocked dropdowns built as `<details>` disclosures; choosing an\n  entry adds or replaces the matching token (`author:`, `label:`,\n  `is:blocked`/`is:unblocked`) in the query and submits. They are conveniences\n  over the search bar, which stays the single source of truth; zero-JS via\n  native disclosures and form posts.\n- **Open/Closed tabs replace the metric tiles and the status dropdown.** Counts\n  render as pills on the tabs. The tabs are links that rewrite the `status:`\n  token in the current query, preserving every other token; the active tab\n  reflects the effective status filter (default: open).\n- **Stacked list rows replace the table.** Row anatomy: state icon, bold title\n  (linking to the detail page), optional Blocked pill, meta line (number,\n  author, opened relative time, updated relative time), label chips, and a\n  right-aligned comment count when nonzero. Blocked remains a derived property\n  (an open blocker exists), never stored.\n- **Detail page is two-column.** Main column: the issue body as the first\n  comment card (author, opened time, edited marker, a role badge when the author\n  is a maintainer), then comment cards, then the composer. Sidebar: Assignees,\n  Labels, Relationships, and Delete sections separated by hairlines, each\n  section's mutation controls inside a disclosure and rendered only for users\n  allowed to use them (manage rights for issue associations; maintainer for\n  delete). Relationships lists both edge directions with each related issue's\n  status; the existing cycle-rejection error surfaces through the existing error\n  banner.\n- **Lifecycle actions live in the composer footer.** Close issue with a reason\n  chooser (completed default, not planned, duplicate) next to the Comment\n  button; Reopen replaces it when the issue is closed. These call the existing\n  close/reopen routes.\n- **Create/edit pages.** Create: required title, description textarea in a\n  Write-tab editor frame with a visible but inert Preview slot (activates when\n  markdown rendering ships), sidebar sections for assignees (including\n  assign-yourself) and label picking, footer with Create, Cancel, and a Create\n  more checkbox that redirects back to the create form instead of the new issue.\n  Edit mirrors create with title + body only. Assignee handles remain\n  unvalidated; the form notes this.\n- **Labels page.** Heading with maintainer-only New label button that expands an\n  inline create row (live-preview chip, name, color with swatch) posting to the\n  existing create-label route; a search input filtering labels by name\n  (server-side, query parameter); rows of chip, hex color, open-issue count, and\n  an overflow disclosure containing edit-in-place and delete. Label deletion\n  behavior is unchanged (cascade off issues; defaults seeded once per ADR 0001 —\n  the page never re-seeds).\n- **Open-issue count per label** is computed with a join at render time; no\n  schema change.\n- **Monochrome-agnostic styling.** The wireframes are lo-fi; the implementation\n  keeps the app's existing styling approach and dark palette, mapping wireframe\n  structure (not colors) onto it. Label chips continue to use each label's\n  stored color.\n\n## Testing Decisions\n\n- **Single seam: the HTTP handler.** All tests drive the app through the tracker\n  factory called with an in-memory store, exactly as the existing form-driven\n  test does: build a request, call the returned handler, assert on status,\n  redirect location, and markers in the rendered HTML.\n- **Good tests assert external behavior, not markup internals.** Assert that the\n  open/closed counts render, that a blocked issue's list row contains the\n  Blocked marker, that a viewer's page omits the New issue and composer\n  affordances, that token search narrows results, that Create more redirects\n  back to the form — not that a specific class name or element nesting is\n  present. String markers should be user-visible text or stable landmarks.\n- **Prior art:** the existing end-to-end form test (`app_test` — HTML forms\n  drive create, lifecycle, labels, assignees, blocks, and comments) is the\n  model: in-memory SQLite via the test store factory, `auth: false`, form posts,\n  HTML assertions. New tests extend this file's style; role-gating tests can\n  construct routed contexts the same way existing routed tests do.\n- **The JSON API tests are untouched** — the API surface does not change.\n\n## Out of Scope\n\n- **Markdown rendering** and therefore Preview activation; the Preview tab ships\n  visibly inert (roadmap).\n- **Personal views** (assigned to me, created by me, recent activity) — deferred\n  until there is real multi-user traffic.\n- **Sort menus** and any other header dropdowns beyond Author, Labels, and\n  Blocked/Unblocked (which now ship — see Implementation Decisions); sort stays\n  fixed at last activity.\n- **Label descriptions** — explicitly decided against; no schema change.\n- **Mobile-specific layouts** — the pages remain simple enough to degrade, but\n  no dedicated responsive pass in this effort.\n- **Pagination**, file attachments, notifications, milestones, projects, and any\n  other GitHub feature without an existing backend.\n- **API or schema changes of any kind.**\n\n## Further Notes\n\n- Visual reference: `wireframes/issue-list.svg`, `wireframes/issue-detail.svg`,\n  `wireframes/issue-new.svg`, `wireframes/labels.svg`, flow overview in\n  `wireframes/flow.svg`, all browsable via `wireframes/index.html`.\n- The wireframes were iterated against GitHub Issues screenshots supplied during\n  the design session; decisions recorded there and folded in here: top bar over\n  sidebar nav, no label descriptions, personal views deferred, Preview marked\n  roadmap.\n- Relative-time formatting (\"3d ago\") appears throughout the wireframes; the\n  current UI shows absolute dates. Treat relative times as the target, but this\n  is a presentation detail, not a contract.\n- If disclosure-based pickers prove awkward for multi-select labeling in\n  practice, the fallback is the current always-visible form for that one\n  section; keep the section anatomy either way.\n",[],[304,505,537,516],"github-style-ui","bd25824a-46f8-4203-963a-29d26806be4f","07-labels-page.md","b3803c74-7fb7-11f1-bc45-1607ee4eb77e","b3318a70-7fb7-11f1-bc45-1607ee4eb77e",244,["D",1784056239217],"# 07 — Labels page\n\n**What to build:** The labels page becomes GitHub-like.

The\n_editability_ decision stands in full; the `*_by` columns and the link\ncreation-pair were removed once the events log (ADR 0004) became the source of\ntruth for provenance.\n\n## Context\n\nWe want to know who created and last changed every piece of user-authored data,\nand we want a uniform convention rather than ad-hoc timestamps per table. Today\nit is inconsistent: issues have `created_by`/`created_at`/`updated_at` but no\n`updated_by`; comments have only `author` + `created_at` and no edit operation\nat all.\n\n## Decision\n\nTwo rules, applied across the whole schema:\n\n1. **Entities carry all four audit columns**: `created_at`, `created_by`,\n   `updated_at`, `updated_by`. Entities are the things a user authors and can\n   later change — **Issue**, **Comment**, **Label**. Consequently, _every entity\n   is editable_ (there is an update operation for each), including comments.\n   `created_by`/`updated_by` hold Val Town handles.\n\n2. **Join / link rows carry only the creation pair**: `created_at` +\n   `created_by` (surfaced with intent-revealing names, e.g.\n   `assigned_at`/`assigned_by` on assignees, `linked_at`/`linked_by` on block\n   edges). Links are immutable — a user _adds_ or _removes_ them, never _edits_\n   one — so `updated_at`/`updated_by` would be meaningless.\n\nNaming: the Comment's `author` column is renamed **`created_by`** so the\nconvention is uniform (the author _is_ the creator).\n\n## Consequences\n\n- Comment editing becomes a real, supported operation (mirrors GitHub).\n- Every table's provenance is queryable in a uniform way; no per-table special\n  cases.\n- `updated_at` combines with the \"touch\" rule (see CONTEXT.md): association\n  changes bump the parent issue's `updated_at` too.\n- Slightly more columns and write-path bookkeeping everywhere — accepted for the\n  auditability and uniformity it buys.\n\n## Amendment (superseded in part by ADR 0004)\n\nOnce the append-only events log (ADR 0004) was adopted, it became the source of\ntruth for _who_ did _what_ and _when_. That makes the `*_by` columns redundant —\nactor is derivable as the latest event for an entity. We therefore revised this\ndecision:\n\n- **Entities keep only `created_at` + `updated_at`** as denormalized columns —\n  they drive hot-path listing and \"last activity\" sorting, which would otherwise\n  require a `MAX(event_timestamp)` aggregate over the log on every render.\n- **`created_by` / `updated_by` columns are dropped.** The actor is derived from\n  the events log, which is already loaded on the only screen that needs it (an\n  entity's detail/timeline view).\n- **Link rows carry no audit columns at all** — assignees and block edges become\n  bare relationship tuples; their provenance lives entirely in events.\n\nWhat stands unchanged from the original decision: **every entity (Issue,\nComment, Label) is editable**, including comments, and the Comment's old\n`author` column is gone (its creator is derived from the `comment.created`\nevent).\n",[],[304,630,632],"bf1eb092-9651-471a-b7da-df0287561a70","0002-blocking-graph-integrity.md","eedbe340-7bf2-11f1-a9f4-1607ee4eb77e",183,["D",1783653141615],"# 0002 — Blocking graph is a strict DAG (reject all cycles)\n\n## Status\n\nAccepted\n\n## Context\n\nIssues can block each other, forming a directed graph stored as edges in\n`issue_tracker_issue_blocks(blocker_id, blocked_id)` (edge direction: blocker →\nblocked).

Keeping the graph a strict DAG also\npreserves the option to add topological \"what's workable now\" ordering later\nwithout retrofitting cycle detection.\n\n## Consequences\n\n- Every edge insert pays for one reachability traversal. For a\n  personal/small-team tracker's graph size this is negligible, and it runs\n  entirely in SQLite.\n- The block graph is guaranteed acyclic, so downstream features may safely\n  assume a topological order exists.\n- This is stricter than GitHub; anyone porting expectations from GitHub should\n  know that A→B→C→A is refused here.\n",[],[304,630,640],"610774cf-6c90-4bf8-91cb-2b82abfa3ecc","0001-seed-default-labels-once.md","ee84afa8-7bf2-11f1-8022-1607ee4eb77e",167,["D",1783653141936],"# 0001 — Seed default labels once, at table creation only\n\n## Status\n\nAccepted\n\n## Context\n\nThe tracker is a drop-in library: `initSchema()` is idempotent and runs on\n**every request** to guarantee the host val's tables exist. We also want to ship\na curated set of default labels (`bug`, `enhancement`, `documentation`,\n`question`, `duplicate`), and labels are user-deletable.\n\nThese two facts collide. If defaults are inserted \"when missing\" inside the\nper-request `initSchema()`, then any default a user deliberately deletes will\nreappear on the very next request — deletion would be impossible for default\nlabels.\n\n## Decision\n\nSeed the default labels **exactly once, in the branch that creates the\n`issue_tracker_labels` table** (i.e. only when it did not previously exist).\nOnce the table exists, `initSchema()` never touches label _rows_ again. After\ncreation the label set belongs entirely to the user: deletes and edits are\npermanent.\n\n## Consequences\n\n- Default labels behave like a starting kit, not enforced state — users can\n  prune or rename any of them and the changes stick.\n- The \"table was just created\" signal must be detected explicitly (e.g. check\n  existence before `CREATE TABLE`, or seed only when a freshly created table is\n  empty on first creation), since `CREATE TABLE IF NOT EXISTS` alone doesn't\n  tell us whether it already had data.\n- A host that wants the defaults back after deleting them must re-add them\n  manually; there is intentionally no auto-heal.\n",[],[304,630,648],"12a719bc-c079-4db1-bbdb-e6251ba56110",135,["D",1783641873285],[321,322,323,324],[304,630],["D",1783635592340],[320,325,329,342,343],[304],["D",1783563523910],["D",1789525245864],{"_98":97,"_105":101},{"_98":97,"_99":-5,"_100":101,"_18":53,"_102":103,"_104":24},{"_13":87,"_31":88,"_41":40,"_89":42,"_90":-5,"_91":-5,"_92":-5,"_93":-5,"_94":-5,"_95":43,"_96":97},"ctx",{"_80":-5,"_125":701,"_702":703,"_704":705,"_706":24,"_707":24,"_708":24,"_709":57,"_710":-5,"_711":-7,"_712":-7,"_713":61,"_714":24,"_715":24,"_716":-5,"_717":24,"_718":24,"_719":24,"_720":-5},"ENV",{"_672":673,"_674":675,"_676":88,"_677":678,"_679":680,"_681":682,"_683":684,"_685":686,"_687":688,"_689":690,"_691":692,"_693":694,"_695":696,"_697":698,"_699":700},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","e87eb04e707cf64e7e532c8e8ec395f209e17f15","RENDER_GIT_BRANCH","POSTHOG_API_TOKEN","phc_nmoyuAkStEZuUp69rYlg1DZgrIt19Gx0Y4Hwf8tGgJP","POSTHOG_API_HOST","https://wart.val.town","WEB_API_TEMPLATE","https://{val}.web.val.run","APP_URL","https://www.val.town","MODULE_URL","https://esm.town","VANITY_WEB_API_TEMPLATE","https://{label}.val.run/","DENOLS_URL","https://lsp.val.town","NODE_ENV","production","CLOUDFLARE_TURNSTILE_SITE_KEY","0x4AAAAAACtaIZJH7s9rBMZ6","GOOGLE_CLIENT_ID","875989696899-jtsqkhlbdv5jrlsk8631p7ipjg3c6o62.apps.googleusercontent.com","STRIPE_PUBLISHABLE_KEY","pk_live_51N2zvWEpZTTLipIkVEwXrUG9AT0yeOOEYxszarZT1jpsZV58Ly6wlg3SltZpHN26CUalOBmUSY7adQRQiSkCZz2500qSXNkf8Y","API_URL","https://api.val.town",[],"preferencesKeybindings","default","preferencesTheme","light","preferencesFixers","preferencesCopilot","preferencesSelectionAi","preferencesCloseBrackets","preferencesChatPanelState","preferencesDprint","preferencesDenofmt","notificationCount","flagDenols","isBusinessOrgMember","businessOrgHandle","isBusinessOrgAdmin","isHigherTownieTier","navCollapsed","currentOrgId"]
