+## Make Your Own Game
+
+Halfstreet is currently meant to be forked as a complete Astro app, not consumed
+as a separate engine package. To make a new story, replace the markdown vault in
+`src/world/` and keep the TypeScript runtime in place.
+
+Start with:
+
+- `src/world/game.md` for the title, starting room, starting inventory, ending
+  priority, opening art, help text, and end text.
+- `src/world/parser.md` for command vocabulary and aliases.
+- `src/world/rooms/`, `src/world/items/`, `src/world/encounters/`, and
+  `src/world/endings/` for story content.
+- `src/world/mechanics/` and `src/world/actions/` for configurable rules and
+  interactions.
+- `src/world/ui.md` for page metadata, footer links, and UI feature switches.
+- `src/world/templates/` for starter files.
+
+Run `npm test` after changing world files. The loader validates wikilinks,
+required sections, frontmatter shape, and references between rooms, items,
+encounters, endings, mechanics, and actions.
+
+## Releases
+
+The footer build number comes from Woodpecker's pipeline number and increments on each CI build.
+The package version is an intentional release label.
+
+Use one of these from a clean worktree when you are ready to cut a release:
+
+```sh
+npm run release:patch  # fixes, typo corrections, small polish
+npm run release:minor  # meaningful playable additions or mechanics
+npm run release:major  # disruptive changes after 1.0.0
+git push --follow-tags
+```
+
+Each release script updates `package.json` and `package-lock.json`, creates a release commit, and tags it.
+
 ## Layout
 
 - `src/engine/` — parser, dispatcher, encounter logic
 - `src/ui/` — terminal renderer, theme, chips
-- `src/world/` — markdown content (rooms, items, encounters, endings)
+- `src/world/` — Obsidian-friendly authoring vault
 - `src/pages/index.astro` — entry page

+# Bug Reporting Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add a "Report a Bug" footer link that opens the Bugpin screenshot widget (forwards to GitHub Issues), plus auto error capture via Bugsink (Sentry-compatible) on every page.
+
+**Architecture:** Two independent flows. Bugpin = user-initiated, lazy-loaded `<script>` widget from `bugpin.half.st`, triggered by a footer `<button>`. Bugsink = background, `@sentry/browser` SDK initialised on page load against a DSN at `bugsink.half.st`. Both credentials are public project tokens and live in `src/world/ui.md`. Both flows are no-ops when not configured.
+
+**Tech Stack:** Astro 6, TypeScript, Zod 4, Vitest 4 (node env, no jsdom), `@sentry/browser` (new dep), Bugpin widget script.
+
+**Spec:** `docs/superpowers/specs/2026-05-17-bug-reporting-design.md`
+
+---
+
+## File map
+
+- `src/world/schema.ts` — **modify**: extend `uiFrontmatterSchema` with optional `bugReport` block.
+- `src/world/schema.test.ts` — **modify**: add accept/reject cases for `bugReport`.
+- `src/world/types.ts` — **modify**: extend `UiConfig` to expose `bugReport`.
+- `src/world/ui.md` — **modify**: add `bugReport` frontmatter.
+- `src/ui/error-tracking.ts` — **create**: reads body data attrs, calls `Sentry.init`. No-op when DSN missing.
+- `src/ui/bug-report.ts` — **create**: wires footer button click to lazy-load Bugpin widget, then call `BugPin.open()`. No-op when config missing.
+- `src/pages/index.astro` — **modify**: render the footer button conditionally, attach data attrs to `<body>`, import the two new modules.
+- `package.json` / `package-lock.json` — **modify**: add `@sentry/browser`.
+- `src/world/TODOs.md:45` — **modify**: rewrite to reflect actual approach.
+
+No DOM tests for the two new UI modules: the project's Vitest config runs in node with no jsdom. Coverage for those modules is `astro check` (type safety) + a manual smoke step at the end of the plan. Schema changes get full unit test coverage via the existing test file.
+
+---
+
+## Task 1: Extend `uiFrontmatterSchema` with `bugReport` (TDD)
+
+**Files:**
+- Modify: `src/world/schema.ts`
+- Modify: `src/world/schema.test.ts`
+
+- [ ] **Step 1: Add the failing tests**
+
+Append these inside the existing `describe('uiFrontmatterSchema', ...)` block in `src/world/schema.test.ts` (just before the closing `})` on line 120):
+
+```ts
+  it('accepts a bugReport block with bugpin and bugsink subconfigs', () => {
+    const data = {
+      pageTitle: 'Halfstreet',
+      description: 'A gothic mystery.',
+      footer: {
+        copyright: '© 2026 Ethan J Lewis',
+        links: [],
+      },
+      bugReport: {
+        enabled: true,
+        label: 'Report a Bug',
+        bugpin: {
+          serverUrl: 'https://bugpin.half.st',
+          apiKey: 'proj_07df4bf91f12445b8ef8c723e865ed7b',
+        },
+        bugsink: {
+          enabled: true,
+          dsn: 'https://231ef18b6b4f426ca249778cfddf821c@bugsink.half.st/1',
+        },
+      },
+    }
+    expect(() => uiFrontmatterSchema.parse(data)).not.toThrow()
+  })
+
+  it('accepts ui config with no bugReport block at all', () => {
+    const data = {
+      pageTitle: 'Halfstreet',
+      description: 'A gothic mystery.',
+      footer: { copyright: '© 2026 Ethan J Lewis', links: [] },
+    }
+    expect(() => uiFrontmatterSchema.parse(data)).not.toThrow()
+  })
+
+  it('rejects a bugpin block with a non-url serverUrl', () => {
+    const data = {
+      pageTitle: 'Halfstreet',
+      description: 'A gothic mystery.',
+      footer: { copyright: '© 2026 Ethan J Lewis', links: [] },
+      bugReport: {
+        enabled: true,
+        bugpin: { serverUrl: 'not-a-url', apiKey: 'proj_x' },
+      },
+    }
+    expect(() => uiFrontmatterSchema.parse(data)).toThrow()
+  })
+
+  it('rejects a bugsink block with a non-url dsn', () => {
+    const data = {
+      pageTitle: 'Halfstreet',
+      description: 'A gothic mystery.',
+      footer: { copyright: '© 2026 Ethan J Lewis', links: [] },
+      bugReport: {
+        enabled: true,
+        bugsink: { dsn: 'whatever' },
+      },
+    }
+    expect(() => uiFrontmatterSchema.parse(data)).toThrow()
+  })
+```
+
+- [ ] **Step 2: Run tests, confirm they fail**
+
+```
+npm test -- src/world/schema.test.ts
+```
+
+Expected: the four new tests fail because `bugReport` is currently unknown (zod by default strips extras, so the "accepts" cases probably pass — but the "rejects" cases will fail because zod will accept anything for unknown fields). Either way, confirm the test runner reports at least the two "rejects" cases as failing.
+
+- [ ] **Step 3: Add the schema fields**
+
+In `src/world/schema.ts`, find `uiFrontmatterSchema` (starts at line 48). Add a `bugReport` field at the end of the object (after `features`, before the closing `})`). Final block:
+
+```ts
+export const uiFrontmatterSchema = z.object({
+  pageTitle: z.string().trim().min(1),
+  description: z.string().trim().min(1),
+  robots: z.string().trim().min(1).default('noindex'),
+  themeColor: z.string().trim().min(1).default('#1a0d00'),
+  footer: z.object({
+    copyright: z.string().trim().min(1),
+    copyrightHref: z.url().optional(),
+    buildLabel: z.string().trim().min(1).default('Build #'),
+    showBuild: z.boolean().default(true),
+    links: z.array(z.object({
+      label: z.string().trim().min(1),
+      href: z.url(),
+    })).default([]),
+  }),
+  features: z.object({
+    chips: z.boolean().default(true),
+    lightMeter: z.boolean().default(true),
+    typedEffect: z.boolean().default(true),
+    roomScroll: z.boolean().default(true),
+  }).default({
+    chips: true,
+    lightMeter: true,
+    typedEffect: true,
+    roomScroll: true,
+  }),
+  bugReport: z.object({
+    enabled: z.boolean().default(false),
+    label: z.string().trim().min(1).default('Report a Bug'),
+    bugpin: z.object({
+      serverUrl: z.url(),
+      apiKey: z.string().trim().min(1),
+    }).optional(),
+    bugsink: z.object({
+      enabled: z.boolean().default(true),
+      dsn: z.url(),
+    }).optional(),
+  }).optional(),
+})
+```
+
+- [ ] **Step 4: Run tests, confirm pass**
+
+```
+npm test -- src/world/schema.test.ts
+```
+
+Expected: all `uiFrontmatterSchema` tests pass (the original two + the four new ones).
+
+- [ ] **Step 5: Commit**
+
+```
+git add src/world/schema.ts src/world/schema.test.ts
+git commit -m "feat(world): add bugReport block to ui schema"
+```
+
+---
+
+## Task 2: Surface `bugReport` on the `UiConfig` type
+
+**Files:**
+- Modify: `src/world/types.ts:64-85`
+
+- [ ] **Step 1: Extend the interface**
+
+In `src/world/types.ts`, replace the existing `UiConfig` interface (currently lines 64–85) with:
+
+```ts
+export interface UiConfig {
+  pageTitle: string
+  description: string
+  robots: string
+  themeColor: string
+  footer: {
+    copyright: string
+    copyrightHref?: string
+    buildLabel: string
+    showBuild: boolean
+    links: Array<{
+      label: string
+      href: string
+    }>
+  }
+  features: {
+    chips: boolean
+    lightMeter: boolean
+    typedEffect: boolean
+    roomScroll: boolean
+  }
+  bugReport?: {
+    enabled: boolean
+    label: string
+    bugpin?: {
+      serverUrl: string
+      apiKey: string
+    }
+    bugsink?: {
+      enabled: boolean
+      dsn: string
+    }
+  }
+}
+```
+
+- [ ] **Step 2: Verify type check passes**
+
+```
+npx astro check
+```
+
+Expected: 0 errors, 0 warnings (or at least no new errors introduced by this change).
+
+- [ ] **Step 3: Commit**
+
+```
+git add src/world/types.ts
+git commit -m "feat(world): expose bugReport on UiConfig"
+```
+
+---
+
+## Task 3: Add real config to `ui.md`
+
+**Files:**
+- Modify: `src/world/ui.md`
+
+- [ ] **Step 1: Edit frontmatter**
+
+Insert this block in `src/world/ui.md` between the `features:` block and the closing `---`, so the frontmatter ends like:
+
+```yaml
+features:
+  chips: true
+  lightMeter: true
+  typedEffect: true
+  roomScroll: true
+bugReport:
+  enabled: true
+  label: "Report a Bug"
+  bugpin:
+    serverUrl: "https://bugpin.half.st"
+    apiKey: "proj_07df4bf91f12445b8ef8c723e865ed7b"
+  bugsink:
+    enabled: true
+    dsn: "https://231ef18b6b4f426ca249778cfddf821c@bugsink.half.st/1"
+---
+```
+
+- [ ] **Step 2: Verify the world loads**
+
+```
+npm test -- src/world/buildWorld.test.ts
+npm test -- src/world/loader.test.ts
+```
+
+Expected: all tests pass — the new frontmatter is valid.
+
+- [ ] **Step 3: Commit**
+
+```
+git add src/world/ui.md
+git commit -m "feat(world): wire bugpin + bugsink credentials in ui.md"
+```
+
+---
+
+## Task 4: Install `@sentry/browser`
+
+**Files:**
+- Modify: `package.json`, `package-lock.json`
+
+- [ ] **Step 1: Install**
+
+```
+npm install @sentry/browser
+```
+
+Expected: a single new dependency added under `"dependencies"` in `package.json`; lockfile updates.
+
+- [ ] **Step 2: Verify**
+
+```
+node -e "require('@sentry/browser')"
+```
+
+Expected: no output and exit code 0.
+
+- [ ] **Step 3: Commit**
+
+```
+git add package.json package-lock.json
+git commit -m "chore: add @sentry/browser for bugsink integration"
+```
+
+---
+
+## Task 5: Create the Bugsink init module
+
+**Files:**
+- Create: `src/ui/error-tracking.ts`
+
+No unit test — Vitest runs in node with no jsdom, and this module only does work in a browser. Coverage is `astro check` (types) + the manual smoke at the end.
+
+- [ ] **Step 1: Write the module**
+
+```ts
+// src/ui/error-tracking.ts
+import * as Sentry from '@sentry/browser'
+
+const dsn = document.body?.dataset.bugsinkDsn ?? ''
+
+if (dsn) {
+  Sentry.init({
+    dsn,
+    tracesSampleRate: 0,
+    replaysSessionSampleRate: 0,
+    replaysOnErrorSampleRate: 0,
+    integrations: [],
+  })
+}
+```
+
+- [ ] **Step 2: Type-check**
+
+```
+npx astro check
+```
+
+Expected: 0 new errors.
+
+- [ ] **Step 3: Commit**
+
+```
+git add src/ui/error-tracking.ts
+git commit -m "feat(ui): initialise sentry browser sdk against bugsink dsn"
+```
+
+---
+
+## Task 6: Create the Bugpin trigger module
+
+**Files:**
+- Create: `src/ui/bug-report.ts`
+
+Module reads config from the footer button's `data-*` attributes, lazy-loads the Bugpin widget on first click, then calls `BugPin.open()`. Subsequent clicks just call `open()` again.
+
+- [ ] **Step 1: Write the module**
+
+```ts
+// src/ui/bug-report.ts
+
+interface BugPinAPI {
+  open: () => void
+  close: () => void
+}
+
+declare global {
+  interface Window {
+    BugPin?: BugPinAPI
+  }
+}
+
+const button = document.querySelector<HTMLButtonElement>('[data-bug-report-trigger]')
+
+if (button) {
+  const serverUrl = button.dataset.bugpinServer
+  const apiKey = button.dataset.bugpinKey
+
+  if (serverUrl && apiKey) {
+    let loadPromise: Promise<void> | null = null
+
+    const ensureLoaded = (): Promise<void> => {
+      if (window.BugPin) return Promise.resolve()
+      if (loadPromise) return loadPromise
+
+      loadPromise = new Promise<void>((resolve, reject) => {
+        const script = document.createElement('script')
+        script.src = `${serverUrl.replace(/\/$/, '')}/widget.js`
+        script.async = true
+        script.dataset.apiKey = apiKey
+        script.addEventListener('load', () => resolve())
+        script.addEventListener('error', () => {
+          loadPromise = null
+          reject(new Error(`Failed to load Bugpin widget from ${script.src}`))
+        })
+        document.head.appendChild(script)
+      })
+
+      return loadPromise
+    }
+
+    button.addEventListener('click', async (event) => {
+      event.preventDefault()
+      button.disabled = true
+      try {
+        await ensureLoaded()
+        window.BugPin?.open()
+      } catch (err) {
+        console.error('[bug-report]', err)
+      } finally {
+        button.disabled = false
+      }
+    })
+  }
+}
+```
+
+- [ ] **Step 2: Type-check**
+
+```
+npx astro check
+```
+
+Expected: 0 new errors.
+
+- [ ] **Step 3: Commit**
+
+```
+git add src/ui/bug-report.ts
+git commit -m "feat(ui): lazy-load bugpin widget on footer click"
+```
+
+---
+
+## Task 7: Wire footer button and module imports in `index.astro`
+
+**Files:**
+- Modify: `src/pages/index.astro`
+
+- [ ] **Step 1: Add config bindings to the frontmatter script**
+
+In the `---` block at the top of `src/pages/index.astro`, after `const remainingFooterLinks = footerLinks.slice(1)`, add:
+
+```ts
+const bugReport = ui?.bugReport
+const bugpinConfig = bugReport?.enabled ? bugReport.bugpin : undefined
+const bugsinkDsn =
+  bugReport?.enabled && bugReport.bugsink?.enabled ? bugReport.bugsink.dsn : ''
+```
+
+- [ ] **Step 2: Add the `data-bugsink-dsn` attribute to `<body>`**
+
+Replace the existing `<body>` opening tag with:
+
+```astro
+<body data-bugsink-dsn={bugsinkDsn}>
+```
+
+- [ ] **Step 3: Add the footer button**
+
+In the `<footer class="mystery-footer">` block (currently lines 89–109), append this AFTER the existing `{remainingFooterLinks.map(...)}` block, before the closing `</footer>`:
+
+```astro
+{bugpinConfig && (
+  <>
+    <span aria-hidden="true">|</span>
+    <button
+      type="button"
+      class="mystery-footer-bug-report"
+      data-bug-report-trigger
+      data-bugpin-server={bugpinConfig.serverUrl}
+      data-bugpin-key={bugpinConfig.apiKey}
+    >{bugReport?.label ?? 'Report a Bug'}</button>
+  </>
+)}
+```
+
+- [ ] **Step 4: Import the two new modules**
+
+Replace the existing module-import script block (currently lines 130–133):
+
+```astro
+<script>
+  import '../ui/terminal.ts'
+  import '../ui/theme.ts'
+</script>
+```
+
+with:
+
+```astro
+<script>
+  import '../ui/terminal.ts'
+  import '../ui/theme.ts'
+  import '../ui/error-tracking.ts'
+  import '../ui/bug-report.ts'
+</script>
+```
+
+- [ ] **Step 5: Add CSS so the button matches the surrounding links**
+
+Open `src/ui/crt.css` and grep for `.mystery-footer` to find the existing footer styles. Add a rule that makes the button look identical to the footer anchors. Append this block at the end of the existing `.mystery-footer` rules (search for `.mystery-footer a` and add directly after that selector's rule):
+
+```css
+.mystery-footer-bug-report {
+  background: none;
+  border: none;
+  padding: 0;
+  margin: 0;
+  font: inherit;
+  color: inherit;
+  text-decoration: underline;
+  cursor: pointer;
+}
+.mystery-footer-bug-report:hover,
+.mystery-footer-bug-report:focus-visible {
+  text-decoration: none;
+}
+.mystery-footer-bug-report:disabled {
+  opacity: 0.5;
+  cursor: progress;
+}
+```
+
+If `.mystery-footer a` styles its anchors differently (e.g. specific color, no underline by default), match those properties instead. Look at the actual `a` rule and copy its `color`/`text-decoration` declarations into `.mystery-footer-bug-report` so the two render visually identically.
+
+- [ ] **Step 6: Run the full type check and build**
+
+```
+npx astro check
+npm run build
+```
+
+Expected: 0 errors, build succeeds.
+
+- [ ] **Step 7: Commit**
+
+```
+git add src/pages/index.astro src/ui/crt.css
+git commit -m "feat(ui): add Report a Bug footer button and wire bug tracking modules"
+```
+

+## Task 8: Update TODOs
+
+**Files:**
+- Modify: `src/world/TODOs.md:45`
+
+- [ ] **Step 1: Rewrite the TODO line**
+
+Replace line 45 of `src/world/TODOs.md`:
+
+```
+- [ ] Set up BugPin as a self-hosted visual bug reporter for the site, then have incoming reports create markdown files under `src/world/bugs/` via a webhook or API bridge so bugs can be tracked in git alongside the game content. Include screenshot/annotation metadata in the markdown and decide whether these bug docs stay outside the world loader or get their own loader later.
+```
+
+with:
+
+```
+- [ ] Add a "Report a Bug" footer link backed by Bugpin (widget at bugpin.half.st → forwards to GitHub Issues). Add Bugsink (@sentry/browser → bugsink.half.st) for automatic JS error capture. Mark complete after manual verification: a test report appears in the Bugpin portal AND a GitHub issue is created AND a thrown error appears in the Bugsink portal.
+```
+
+- [ ] **Step 2: Commit**
+
+```
+git add src/world/TODOs.md
+git commit -m "docs: rewrite TODO 45 to reflect Bugpin/Bugsink approach"
+```
+
+---
+
+## Task 9: Manual smoke test
+
+**Pre-req:** the Bugpin GitHub integration must be configured server-side before user reports will create issues. See spec §5. Steps below test the widget plumbing regardless.
+
+- [ ] **Step 1: Start dev server**
+
+```
+npm run dev
+```
+
+Open the URL it prints (default `http://localhost:4321`).
+
+- [ ] **Step 2: Verify the footer button renders**
+
+In the rendered footer at the bottom of the page, confirm "Report a Bug" appears after "Source Code", styled like the surrounding links.
+
+- [ ] **Step 3: Verify the widget lazy-loads**
+
+Open DevTools → Network. Filter for `widget.js`. Confirm NO request to `bugpin.half.st/widget.js` on cold page load.
+
+Click "Report a Bug". Confirm:
+- A single GET to `https://bugpin.half.st/widget.js` (status 200).
+- The Bugpin dialog opens.
+- Take a screenshot, write "smoke test" in the note, submit.
+- The dialog closes / shows a success state.
+
+Re-click "Report a Bug". Confirm NO second `widget.js` request — only the dialog re-opens.
+
+- [ ] **Step 4: Verify Bugpin received the report**
+
+Open `https://bugpin.half.st/portal`. Confirm the "smoke test" report appears with the screenshot attached.
+
+If the GitHub integration is configured: confirm a matching issue appears in the halfstreet GitHub repo.
+
+- [ ] **Step 5: Verify Bugsink captures an uncaught error**
+
+In the dev server's running page, open DevTools console and run:
+
+```js
+setTimeout(() => { throw new Error('bugsink smoke test') }, 0)
+```
+
+Open `https://bugsink.half.st`. Confirm a "bugsink smoke test" event appears within ~30 seconds.
+
+- [ ] **Step 6: Verify the launcher styling is acceptable**
+
+After step 3, the Bugpin widget's built-in floating launcher may now also be visible on the page. If its presence is visually objectionable, add a CSS rule to `src/ui/crt.css` targeting the Bugpin host element (inspect the DOM to find the selector — Bugpin uses Shadow DOM with a custom-element host like `<bugpin-widget>` or similar). Example:
+
+```css
+bugpin-widget,
+[data-bugpin-launcher] {
+  display: none !important;
+}
+```
+
+If this turns out to be needed, commit the CSS as `style(ui): hide bugpin built-in launcher (we have our own trigger)`. If the launcher's appearance is fine as-is, skip this step.
+
+- [ ] **Step 7: Mark TODO #45 complete**
+
+Once steps 1–5 all pass, edit `src/world/TODOs.md` line 45, change `- [ ]` to `- [x]`, and commit:
+
+```
+git add src/world/TODOs.md
+git commit -m "chore: mark TODO 45 complete"
+```
+
+---
+
+## Done criteria
+
+All of the following are true:
+
+- `npm test` passes.
+- `npx astro check` reports 0 errors.
+- `npm run build` succeeds.
+- Manual smoke (Task 9 steps 1–5) all pass.
+- TODO #45 is `[x]`.

+# Phase 2 — Halfstreet Content Rewrite Roadmap
+
+**For:** authoring the Halfstreet content bible into markdown for Obsidian editing, now that the engine prereqs have landed.
+
+**Bible:** `docs/superpowers/specs/halfstreet-bible.md`
+**Engine prereqs spec:** `docs/superpowers/specs/2026-05-09-mystery-engine-prereqs-design.md`
+**Engine prereqs plan:** `docs/superpowers/plans/2026-05-09-mystery-engine-prereqs.md` (✅ shipped on `feat/engine-prereqs`)
+
+---
+
+## What the engine can now express
+
+After Phase 1, the markdown content layer supports every interaction the bible specifies:
+
+- **Rooms** — frontmatter exits (n/s/e/w/u/d), locked exits with item or flag requirements, encounter triggers, safe-room flag, and three description sections (`## first-visit`, `## revisit`, `## examined`). Wikilinks (`[[room-id]]`) work for cross-references.
+- **Items** — `readable` (with `## read` body section), `lightable` (with `## lit` / `## extinguished`), `lighter` + `lighterUses` (with `## lighter-empty`), arbitrary `initialState`, multiple aliases. Non-key items (clocks, music boxes, etc.) can live as room scenery referenced in encounters.
+- **Encounters** — phase descriptions and transition narration in markdown sections; phase state machine in `encounters.ts` references prose via `narration('id', 'key')`. Transitions support `verb`, `target`, `requires.item` (gates the instrument), `to`, `narration`, `resolveCost`.
+- **Endings** — `whenFlags` predicate plus markdown body. Priority order is `true` → `wrong` → `bad`; first match fires. `_never: true` sentinel keeps placeholders from auto-firing.
+- **Verbs the parser/dispatcher handle:** `look`, `examine`, `take`, `drop`, `inventory`, `wait`, `go` + directions, `read`, `light`, `extinguish`, `use`, `attack`, plus `verb-target-prep` for `light X with Y` and `use X on Y`. Stop-words (`at`/`the`/`a`/`an`) are stripped. Ambiguous nouns prompt for disambiguation.
+
+If the bible needs anything beyond this list, that's a Phase 1.5 engine task — surface it and we'll add a small follow-up plan.
+
+---
+
+## What needs authoring
+
+A rough inventory derived from the bible. Counts include the existing 3 rooms / 3 items / 1 encounter / 3 endings (which need rewriting in the new tone, not just additions).
+
+| kind | count | source in bible |
+|---|---|---|
+| Rooms | 25–28 | "Existing House Rooms" + "Additional Rooms" + "Altered / Conditional Rooms" |
+| Carry-able items | ~12 | "Inventory Items" + the existing matches/lamp/letter |
+| Non-key (scenery) items | ~10 | "Non-Key Items" |
+| Encounters | ~17 | "Revised Encounter Notes" + "Expanded Encounters" + the existing rat |
+| Endings | 5 | "Expanded Endings" — true / wrong / bad / replacement / mercy |
+| Story flags | ~10 | "Expanded Story Flags" |
+
+The bible already supplies:
+- **Verbatim prose** for the opening scene, the basilisk encounter, the child-beneath-the-well encounter, the toy dog, and all five endings — paste these in as-is.
+- **Summaries** for each room (1–2 sentences) — expand to full first-visit + revisit + examined prose in Obsidian.
+- **Interaction descriptions** for each item — expand to full long-description prose plus relevant body sections.
+- **Resolution paths** for each encounter — translate into phase + transition narration.
+
+---
+
+## Authoring workflow in Obsidian
+
+1. **Open the vault.** `src/world/` is configured as an Obsidian vault (see `.obsidian/`). Open that folder in Obsidian. Wikilinks to room/item/encounter ids resolve as graph edges.
+2. **Branch.** Work on a Phase 2 branch (e.g. `feat/content-rewrite`) so prose iteration doesn't pile onto `main`. Commit small, frequent slices — a room or two per commit reads cleanly in PR.
+3. **Edit the markdown directly.** The dev server (`npm run dev`) runs Astro's HMR; saving a `.md` file reloads the browser with the new prose.
+4. **Test as you go.** `npm test` covers the engine and loader; round-trip / cross-reference validation runs at world assembly. A typo in a wikilink target throws on load — check the dev console.
+5. **Use `_never: true`** on any ending whose flag conditions you haven't decided yet. Replace with real flags once authored.
+
+---
+
+## Suggested authoring sequence
+
+Phase 2 is large enough that I recommend slicing by *region*, not by *kind*. A fully-authored region (rooms + items + encounters there) is playable end-to-end and produces a useful test loop. Mixing kinds across the whole house drags the playable surface to zero for a long time.
+
+Suggested slices:
+
+1. **Rewrite the opening slice** in the bible's voice. The Gate, Foyer, Hallway, Cellar Stair — The Gate is the opening room, and the player should begin there carrying the folded letter, matchbook, and broken cigarette. This is the smallest possible PR and de-risks the voice direction before scaling up.
+2. **Main-floor expansion** — Parlor, Study, Dining Room, Conservatory, Smoking Room, Music Room, Servants' Passage, Laundry. These connect to the existing Hallway. Add the items each room references (candlestick, pruning-shears, silver-lighter, music-box-key, damp-sheet) and their encounters (window-guest, ivy-figure, covered-cage, piano-echo, breathing-wall, linen-shape).
+3. **Upper floor** — Stair, Bedroom, Nursery, Attic. Items: child's drawing, music-box (non-key), toy dog. Encounters: stair-sleeper.
+4. **Garden + grounds** — Back Door, Garden, Well, Well Shaft. Encounter: garden-procession, child-beneath-the-well (verbatim prose in bible).
+5. **Lower passages** — Tunnel, Antechamber, Vault, Ossuary, Flooded Passage, Root Chamber, Burial Gallery, Cistern. Items: burial-ring, toy-boat, family-register. Encounters: bone-keeper, reflection, root-movement, portrait-woman.
+6. **Chapel + basilisk** — verbatim prose in bible. Items: silver-vial. Encounter: basilisk (replaces chapel-watcher).
+7. **Conditional / altered rooms** — wrong-hallway, returned-nursery, rain-room. These appear only after specific flags.
+8. **Endings** — true, wrong, bad, replacement, mercy. Verbatim prose; just wire the `whenFlags` per the bible's conditions.
+9. **Polish pass** — re-read the whole transcript top to bottom in the browser. Catch tonal drift, stale wikilinks, dead encounters, items with no resolution.
+
+Within each slice, the order that minimizes broken intermediate state:
+
+1. Author the room files first (with placeholder exits to non-existent rooms commented out or marked `null` until the destination is authored — the loader's cross-ref validation will fail otherwise).
+2. Author item files referenced by the rooms.
+3. Author encounter files (frontmatter + narration sections), then update `encounters.ts` with the phase/transition state machine.
+4. Add any new flags to `flags.ts` or wherever they land (no central registry today — they're set/read ad hoc).
+5. Set ending `whenFlags` once enough flags exist to specify the conditions.
+
+---
+
+## Open questions / things to watch
+
+- **Flag registry.** The bible introduces ~10 story flags. Today they're untyped strings flowing through `state.flags`. As the count grows, consider a `flags.ts` module exporting the canonical names so typos surface at compile time. Not required for Phase 2 to ship; might be a small Phase 1.5 task.
+- **Scenery items.** Bible's "Non-Key Items" (grandfather-clock, music-box, dinner-place-setting, etc.) are objects the player interacts with but cannot carry. Decide whether to model them as untakeable items (frontmatter `takeable: false`) or as room-state with custom verbs in `encounters.ts`. The former is simpler if `examine` and one or two specific verbs cover the interaction; the latter is needed for richer state machines (e.g. setting the grandfather clock to a specific time).
+- **House-altering geometry.** "wrong-hallway" and "returned-nursery" are the same physical space with different prose after a flag is set. Today rooms have one set of descriptions. Either: (a) author them as separate room ids and gate access with locked-exit + flag conditions; (b) extend the room schema to support conditional descriptions. (a) is smaller; (b) is more elegant. Pick (a) until it bites.
+- **Resolve mechanic.** Bible says "violence usually worsens outcomes" and assumes a Resolve ladder. The engine has `resolveLevel` but the bible's expected costs/recoveries aren't fully specified. Phase 2 can either (a) commit to the existing levels and let prose lean on them informally, or (b) write a short addendum nailing down which transitions cost what. Lean toward (a) until inconsistencies emerge.
+- **Disambiguation in practice.** With ~12 carry-able items, watch for shared aliases (`key` covers `rusted-key` / `music-box-key` / `burial-ring`'s "ring"). The disambiguation prompt is in place but the prose for it is generic ("Which X — A, or B?"). Acceptable as-is; revisit if it reads clunky.
+
+---
+
+## Definition of done for Phase 2
+
+- All bible rooms, items, encounters, and endings live in `src/world/` markdown.
+- A first playthrough reaches the true ending in 45–90 minutes.
+- All five endings are reachable by some flag combination and tested at least once.
+- No cross-reference errors at world load; all encounter narrations resolve.
+- Prose passes a re-read by the author against the bible's voice rules.
+- Polish items deferred from Phase 1 (transcript scrolling, cursor blink rate, line fade, scanline toggle) are still deferred — Phase 2 is content-only.
+
+---
+
+## When ready to start
+
+Brainstorm Slice 1 (existing 3 rooms in new tone) → spec → plan → author. The brainstorming will be quick because the bible already specifies most of what's needed; the spec is mostly a checklist and a tone-test paragraph; the plan is "edit these N markdown files." After Slice 1 ships, decide whether to continue slice-by-slice in plans or shift to a looser working-mode where each region's PR is its own thing.

+# Mystery Engine Prereqs — Design
+
+**Status:** approved 2026-05-09
+**Goal:** land the engine work that the Halfstreet content bible depends on, so that Phase 2 (full bible content draft into markdown) can author every room/item/encounter/ending the bible specifies without engine gaps.
+
+**Scope:** the hard prerequisites and "should-fix while you're in there" items from `docs/superpowers/specs/halfstreet-followon-notes.md`. Polish items (8–11) are explicitly deferred.
+
+**Out of scope:** any new prose authoring. This round is engine-only. Phase 2 gets its own spec.
+
+---
+
+## 1. New verbs: `read`, `light`, `extinguish`
+
+The parser already aliases these to canonical `Verb` values; the dispatcher does not handle them.
+
+### Schema additions (`Item`)
+
+All optional. Items that don't set them behave as today.
+
+| field | type | meaning |
+|---|---|---|
+| `readable` | `boolean` | item supports `read X` |
+| `lightable` | `boolean` | item supports `light X` / `extinguish X`; toggles `state.lit` |
+| `lighter` | `boolean` | item can act as the light source for another item |
+| `lighterUses` | `number` | optional remaining-charges counter (matches: 4 by convention; absence = unlimited) |
+
+Body sections (markdown):
+
+- `## read` — prose returned by `read X`. Required iff `readable: true`.
+- `## lit` — narration when `light X` succeeds. Optional; falls back to `"It catches."`
+- `## extinguished` — narration when `extinguish X` succeeds. Optional; falls back to `"The flame dies."`
+- `## lighter-empty` — narration when a lighter's `lighterUses` reaches 0. Optional; falls back to `"It is spent."`
+
+### Dispatcher behavior
+
+`read X`:
+- if `!item.readable` → `"There's nothing to read on it."`
+- else → narrate the item's `## read` text.
+
+`light X` (implicit lighter):
+- if `!item.lightable` → `"You can't light that."`
+- if `state.lit === true` → `"It's already lit."`
+- find an inventory item with `lighter: true` (and either no `lighterUses` field, or `lighterUses > 0`):
+  - if none and inventory contains a depleted lighter → `"You have nothing to light it with."` (with a hint that the spent lighter is depleted)
+  - if none at all → `"You have nothing to light it with."`
+- else: decrement `lighterUses` on the chosen lighter (if present); set `target.state.lit = true`; narrate the target's `## lit` section. If decrement reached 0, additionally narrate the lighter's `## lighter-empty` section.
+
+`light X with Y`:
+- as above but Y must be the inventory item used. Errors: Y not in inventory, Y not a lighter, Y depleted.
+- on success, same state mutations.
+
+`extinguish X`:
+- if `!item.lightable` → `"You can't extinguish that."`
+- if `state.lit !== true` → `"It isn't lit."`
+- else: set `state.lit = false`; narrate `## extinguished`.
+
+### Parser additions
+
+New command kind:
+
+```ts
+{ kind: 'verb-target-instrument', verb, target: NounRef, instrument: NounRef }
+```
+
+Parsing rule: when the noun-phrase tokens (after the verb and any pronoun handling) contain the literal word `with` between two recognized nouns, split into target (left of `with`) and instrument (right of `with`). Both must resolve via the same noun-resolution path used today (visible nouns + inventory). If either fails to resolve, fall back to the current `unknown-noun` behavior.
+
+`with` is also legal as a no-op separator for verbs that don't accept instruments (e.g. `examine letter with care`) — for safety, only `light` consumes the instrument arm in this round; other verbs treat the instrument tail as part of the target phrase and re-resolve as today (no behavior change).
+
+---
+
+## 2. `use` verb
+
+`use X` and `use X on Y` route through the existing encounter dispatcher (`applyVerbToEncounter`). Encounters declare resolutions in their phase transitions; `use` is intentionally thin.
+
+- `use X` → `verb-target` with verb=`use`, target=X. If no encounter consumes it: `"You can't think how to use that here."`
+- `use X on Y` → `verb-target-instrument` with verb=`use`, target=X, instrument=Y. The dispatcher routes the verb+target into `applyVerbToEncounter` as today; the encounter's `requires.item` mechanism (already implemented) gates the transition on the instrument being in inventory. The parser-level instrument is therefore a UX nicety: it lets the player type the form the bible uses, and we can validate the typed instrument matches the transition's `requires.item` when present (mismatch → fallback narration "That isn't going to help.").
+
+No special-case dispatcher handler beyond the fallback narration. No new fields on `EncounterDef`.
+
+---
+
+## 3. Disambiguation
+
+Today the parser returns `unknown-noun` when multiple visible aliases match a noun phrase. Replace with an explicit ambiguous variant.
+
+### Parser
+
+New `ParsedCommand` variant:
+
+```ts
+{ kind: 'ambiguous', verb: Verb, rawNoun: string, candidates: string[] }
+```
+
+Returned when ≥2 entries in `visibleNouns ∪ inventory` match the same alias. `candidates` is the list of canonical ids.
+
+The existing `disambiguation` reply variant stays as-is; the parser already handles single-word reply matching.
+
+### Dispatcher
+
+On `kind: 'ambiguous'`:
+- set `state.pendingDisambiguation = { verb, candidates }`
+- emit a single narration: `"Which X — A, B, or C?"` where `X` is the `rawNoun` and A/B/C are the `short` strings of each candidate item.
+
+On `kind: 'disambiguation'` reply (already wired):
+- read `state.pendingDisambiguation`, clear it, re-issue the original verb against the chosen canonical id.
+
+### Edge cases
+
+- If the player issues a fresh command (not a single-word disambiguation reply) while `pendingDisambiguation` is set, clear it and proceed normally.
+- If candidates resolve to identical canonical ids (shouldn't happen given current schema), prefer the first; no error.
+
+---
+
+## 4. Ending UI + flag matching
+
+### Dispatcher
+
+After every dispatched turn (and only on turns that succeeded — meta-commands and parse failures don't trigger ending evaluation), iterate `world.endings`:
+
+- For each `endingId` in a fixed priority order (`true` > `wrong` > `bad` — declared order in `world.endings`), check that **every** key in `whenFlags` is present in `state.flags` and has the matching value. First match wins.
+- On match: set `state.endedWith = endingId`; append a narration event with `kind: 'ending'` and the body prose (already loaded from the ending markdown). Mark the run as ended (subsequent turns are rejected with a "the game has ended" narration until restart).
+
+Ending evaluation is pure — same inputs, same outputs.
+
+### UI (terminal renderer)
+
+- `kind: 'ending'` events render with a separator line above, the prose centered or left-aligned with extra vertical gap, no `>` prompt afterward.
+- Input field disables (`disabled` attribute or readonly + faded styling).
+- Footer chips replace the regular set with `[R] Restart`, `[U] Undo`.
+- `restart` (typed or button) resets state and re-enables input.
+- `undo` (typed or button) pops the last turn (existing behavior) and re-enables input if the popped state had no ending.
+
+---
+
+## 5. Should-fix items (in scope)
+
+### 5a. Parser stop-word strip
+
+Before noun resolution, strip leading occurrences of `at`, `the`, `a`, `an` from the noun-phrase tokens. So `look at the lamp` → tokens `[lamp]` for matching. The verb itself is not touched.
+
+Affects only the noun phrase. Stop-words *between* meaningful tokens are left alone (e.g. `light lamp with the matches` strips the leading-of-instrument `the`).
+
+### 5b. Remove `theme` from `GameState`
+
+`theme` is a UI preference, not game state. Today, clicking `[B]/[C]` updates DOM + localStorage but not `state.theme`, then the next `theme` meta-verb toggles from a stale value.
+
+Changes:
+- delete `theme` field from `GameState` and from save format
+- `theme` meta-verb becomes a UI-layer action: dispatcher emits a `kind: 'ui-toggle-theme'` event that the terminal handles
+- migration: existing saves drop the `theme` field on load (forward-compatible)
+
+### 5c. Widen `RoomState` type
+
+Today: `Record<string, string | boolean | number>`, but `droppedItems` / `takenItems` store `string[]` via `as` casts.
+
+Change: `Record<string, string | boolean | number | string[]>`. Remove all `as` casts in dispatcher and engine paths that touch `roomState`. No runtime change.
+
+### 5d. Self-contained locked-exit dispatcher test
+
+The current `dispatcher.test.ts` "opens a locked exit" test is a stub. Add a 15-line synthetic world fixture (two rooms, one key item, one locked exit) and exercise:
+- locked exit blocks movement with the `lockedNarration`
+- carrying the required item permits movement
+- the key is not consumed by passage (unless flagged so in future; current behavior: not consumed)
+
+---
+
+## 6. Test plan
+
+TDD throughout, per existing project conventions.
+
+| area | test types |
+|---|---|
+| schema additions | Zod parse tests (valid + each invalid shape) |
+| `read` verb | dispatcher unit (readable, non-readable, missing item) |
+| `light` / `extinguish` | dispatcher unit (lightable + lighter, lighter-with-charges decrement, lighter-empty fallthrough, explicit `with`, error paths) |
+| `use` verb | dispatcher unit (no encounter consumes → fallback; encounter consumes → routed) |
+| disambiguation | parser unit (ambiguous candidates), dispatcher round-trip (prompt → reply → re-issue) |
+| ending detection | dispatcher unit per ending; priority order; ended-state turn rejection |
+| stop-word strip | parser unit (`look at lamp`, `read the letter`, etc.) |
+| theme removal | save round-trip drops field; `theme` meta-verb emits UI event, no state mutation |
+| roomState widen | type-level (compile passes); existing tests unchanged |
+| locked-exit | new synthetic-world dispatcher test |
+| manual playthrough | golden path on current 3-room world after all changes |
+
+---
+
+## 7. Out of scope — follow-up tracker
+
+These are tracked but not part of this round:
+
+- Transcript scrolling (PageUp/PageDown)
+- Cursor blink at 1.05 Hz
+- Old-line opacity fade at top of transcript
+- Scanline accessibility toggle (`[?]` settings dropdown — important for photosensitivity)
+
+---
+
+## 8. After this lands
+
+Phase 2 brainstorming → spec → plan: full bible content draft. All 25+ rooms, all bible items, all encounters, all 5 endings authored to markdown for Obsidian editing. Engine will support every interaction the bible specifies by then.

+# Bug reporting: Bugpin (user) + Bugsink (auto)
+
+**Status:** Approved design, ready for implementation plan.
+**Date:** 2026-05-17
+
+## Goal
+
+Let visitors report bugs in the Halfstreet site with a screenshot, and capture uncaught JavaScript errors automatically. Reports should flow to systems already running on the `half.st` host so there is no new infrastructure to manage.
+
+## Two distinct flows
+
+| | Bugpin | Bugsink |
+|---|---|---|
+| Trigger | Visitor clicks "Report a Bug" in footer | Uncaught JS error |
+| Capture | Screenshot, annotations, free-text note, console/network metadata | Stack trace, breadcrumbs |
+| Destination | Bugpin portal → auto-creates a GitHub Issue in the halfstreet repo | Bugsink portal only |
+| Library | `bugpin.half.st/widget.js` (lazy-loaded on click) | `@sentry/browser` npm package (loads on every page) |
+
+The two are intentionally separate. Bugpin owns user-facing reports; Bugsink owns automatic exception capture. Sentry's user-feedback widget is **not** used — that would overlap Bugpin and muddle the responsibilities.
+
+## Components
+
+### 1. Footer link
+
+`src/pages/index.astro`
+
+Add "Report a Bug" to the footer chain after the existing links. Render as a `<button>` styled to match the surrounding `<a>` elements so it can dispatch JS without a hash-link navigation.
+
+Final order:
+`© 2026 Ethan J Lewis | GNU 3.0 | Build #<n> | Source Code | Report a Bug`
+
+The button only renders when `world.ui.bugReport?.enabled` is true and a Bugpin server URL is configured. If either is missing, the button is omitted (local dev stays clean).
+
+### 2. Config
+
+`src/world/ui.md` — add a `bugReport` frontmatter block:
+
+```yaml
+bugReport:
+  enabled: true
+  label: "Report a Bug"
+  bugpin:
+    serverUrl: "https://bugpin.half.st"
+    apiKey: "proj_07df4bf91f12445b8ef8c723e865ed7b"
+  bugsink:
+    enabled: true
+    dsn: "https://231ef18b6b4f426ca249778cfddf821c@bugsink.half.st/1"
+```
+
+The Bugpin project API key and the Bugsink DSN are both designed to ship to clients (they are public credentials that authenticate the project, not the operator), so checking them into the repo is acceptable.
+
+`src/world/schema.ts` — extend `uiFrontmatterSchema` with an optional `bugReport` object:
+
+```ts
+bugReport: z.object({
+  enabled: z.boolean().default(false),
+  label: z.string().trim().min(1).default('Report a Bug'),
+  bugpin: z.object({
+    serverUrl: z.url(),
+    apiKey: z.string().trim().min(1),
+  }).optional(),
+  bugsink: z.object({
+    enabled: z.boolean().default(true),
+    dsn: z.url(),
+  }).optional(),
+}).optional(),
+```
+
+`src/world/types.ts` — extend `UiConfig` with the matching TypeScript shape.
+
+### 3. Bugpin lazy loader
+
+New module: `src/ui/bug-report.ts`
+
+Responsibilities:
+- Read Bugpin config from a `data-*` attribute on the footer button (so the module stays free of Astro imports).
+- On first click, inject `<script src="${serverUrl}/widget.js" data-api-key="${apiKey}" async>` into `<head>`. Hide Bugpin's built-in floating button using whatever option the widget exposes (likely `data-hidden="true"` or a CSS rule scoped via the widget's Shadow DOM hook — confirm against the install guide during implementation).
+- Once the script resolves, call `window.BugPin.open()`.
+- Cache the loaded state on a module-level flag; subsequent clicks just call `open()` again.
+- If the script fails to load (offline, server down), log to the console and surface a minimal inline message ("Couldn't open bug reporter — try refreshing"). Do not break the page.
+
+Wire-up in `src/pages/index.astro`:
+- The footer button gets `data-bug-report-trigger`, `data-bugpin-server`, `data-bugpin-key` attributes.
+- A new `<script>` block imports `../ui/bug-report.ts` alongside the existing terminal/theme imports.
+
+The lazy-load is deliberate: ~150 KB of widget code stays off the cold load for visitors who never click.
+
+### 4. Bugsink init
+
+New module: `src/ui/error-tracking.ts`
+
+Responsibilities:
+- Add `@sentry/browser` as a dependency.
+- Read the DSN from a `data-bugsink-dsn` attribute set on `<body>` (or a meta tag) so the module is server-render-agnostic.
+- On import, call:
+  ```ts
+  Sentry.init({
+    dsn,
+    tracesSampleRate: 0,
+    replaysSessionSampleRate: 0,
+    replaysOnErrorSampleRate: 0,
+    integrations: [],
+  })
+  ```
+- If `dsn` is missing or `bugsink.enabled` is false, no-op.
+
+Error-capture only — no performance tracing, no session replay. Keeps the bundle small and avoids accidentally shipping a replay tool we didn't design for.
+
+Wire-up in `src/pages/index.astro`:
+- A new `<script>` block imports `../ui/error-tracking.ts` near the existing imports.
+
+### 5. Bugpin GitHub wiring
+
+Out of scope for the code change, but recorded here so it isn't lost during implementation:
+
+1. In the halfstreet GitHub repo, create a classic personal access token (or fine-grained equivalent) with `repo` scope.
+2. In Bugpin admin (https://bugpin.half.st/portal): Projects → halfstreet → Integrations → GitHub. Paste the token, select the halfstreet repo, set default labels (e.g., `bug`, `user-report`).
+3. Verify by submitting a test report from the footer link and confirming an issue appears in GitHub.
+
+## Out of scope
+
+- **Markdown files under `src/world/bugs/`.** Original TODO #45 proposed this; explicitly dropped — Bugpin's portal + GitHub Issues replace that storage path.
+- **Gitea mirroring.** Bugpin does not natively support Gitea. Deferred until there's clear value in a Bugpin → Gitea bridge. The front-end design does not preclude this; it would be a server-side addition on the Bugpin host.
+- **Sentry user-feedback widget.** Bugpin owns user reports; Bugsink stays auto-only.
+- **PII redaction policy.** Bugpin's widget includes a built-in blur tool; Bugsink only captures stack traces, not request bodies. No additional scrubbing layer.
+
+## Risks / things to verify during implementation
+
+- **Bugpin "hide default button" mechanism.** Docs mention a floating launcher; the exact opt-out attribute needs to be confirmed against the install guide or the widget source. If no opt-out exists, fall back to CSS that hides the widget's launcher selector inside its Shadow DOM root (or wrap with a custom-element rule).
+- **Bugsink Sentry SDK compatibility.** Bugsink claims Sentry-SDK compatibility but tested feature surface varies. Verify with `@sentry/browser` v9 (current stable as of 2026-05) — if a specific minor version is needed, pin it.
+- **Cold-start cost.** Bugsink adds ~30–40 KB gzipped to the page. Acceptable for an authored, low-traffic site; flag if budget gets tight.
+
+## TODOs.md update
+
+Replace line 45 with:
+
+```
+- [ ] Add a "Report a Bug" footer link backed by Bugpin (widget at bugpin.half.st → forwards to GitHub Issues). Add Bugsink (@sentry/browser → bugsink.half.st) for automatic JS error capture.
+```
+
+Mark complete once the implementation lands and a test report has appeared in both Bugpin's portal and GitHub.
+
+## Files touched (preview)
+
+- `src/world/ui.md` — add `bugReport` block.
+- `src/world/schema.ts` — extend `uiFrontmatterSchema`.
+- `src/world/types.ts` — extend `UiConfig`.
+- `src/pages/index.astro` — render the button conditionally, wire data attributes, import the two new UI modules.
+- `src/ui/bug-report.ts` — **new**, lazy loads the Bugpin widget on click.
+- `src/ui/error-tracking.ts` — **new**, initializes Sentry SDK against Bugsink DSN.
+- `package.json` / `package-lock.json` — add `@sentry/browser`.
+- `src/world/TODOs.md` — rewrite line 45.

+- [x] Need to add help text when user types "help". This should give them some common commands and explain the concepts behind text adventure games. It should also include an exceprt at the beginning from the opening text.  "You arrive at the address, but you do not remember what has happened. The road behind you is gone...". The help text should disappear after the user types a new prompt (i.e., it's not persistent).
+- [x] Need to add  the tiles from mobile to desktop view.
+- [x] Enhance tiles with contextual awareness, enabling tiles to appear in rooms when appropriate (e.g. "attack rat").
+- [x] Add a tile for USE 
+- [x] Add a footer with "By [Ethan J Lewis](https://ethanjlewis.com) | [Source Code](https://half.st/ejlewis/halfstreet) | [GNU General Public License v3.0](https://half.st/ejlewis/halfstreet/src/branch/main/LICENSE)"
+- [x] Add "Half Street" as ASCII Art to the intro text.
+- [x] Add logic to make the last sentence in the examined description conditional. This is where we'll list items in the room. (e.g., "The hallway runs further than the house should be wide. The dust on the floor is undisturbed except where you have walked. *The oil lamp is on the side table.*")
+- [x] Fix mobile - scrolling issue (page grows as the terminal grows).
+- [x] Fix mobile - ascii text art at beginning too big to render
+- [x] Feature: Ability to retain console history, e.g., scroll through previous commands with up and down arrows.
+- [x] Feature: Grey italicized "type here..."  text that appears near the terminal if the user doesn't click into the terminal within 30 seconds of entering the game or click the help button. The text disappears once a user clicks in the terminal, or selects a card.
+- [x] Change footer to "Copyright (C) 2026 [Ethan J Lewis](https://ethanjlewis.com) | [GNU 3.0](https://half.st/ejlewis/halfstreet/src/branch/main/LICENSE)| [Source Code](https://half.st/ejlewis/halfstreet)"
+- [x] Wire up favicon
+- [x] Feature: Provide ability to change cursor type. Block, underline, and whatever we have now.
+- [x] Feature: Move cursor selection and screen toggle to option menu. Put the option menu where the screen toggle currently is. Give it a gear icon and let it be a tile.
+- [x] Bug: gear icon too small.
+- [x] Bug: option for cursor should show cursor in terminal when option menu is open.
+- [x] Bug: cursor toggle not affecting the cursor at all.
+- [x] Bug: idle text appearing above the tiles instead of in the terminal line.
+- [x] Feature: / brings focus to terminal
+- [x] Feature: Add "Restart" option to option menu
+- [x] Bug: gear icon is still wayyyyyyy toooo smallllll it needs to be like 4x larger at least.
+- [x] Add a "wait" tile.
+- [x] If the user says "light match" or "light match" the response should be "use match with what?"
+- [x] If the user says "use match with letter" they should burn the letter.
+- [x] There should be a lighter in the smoking room that allows unlimited lighting.
+- [x] Create a mechanic that asks "Are you sure?" before taking critical actions like attacking or other game-changing mechanics that might affect the final ending.
+- [ ] Add lightened descriptions to darkened rooms. About half the rooms should be too dark to see anything (affects ability to move forward, can't see exits or encounters, except for maybe hints at the encounters, like sounds or shapes in the dark) Add frontmatter property to all rooms: (dark: true/false). Make text in darkened rooms a grey color.
+- [ ] Implement a simple "stealth mechanic", where sometimes it's advantageous to have the light out.
+- [ ] Implement a simple (optional?) minimap in the UI? - Maybe tied to an item? Once you get the map the minimap appears? Can we POC it?
+- [x] Add a mechanic where after the player waits 3 times or moves six times the light goes out and needs to be relit. Or something along those lines. We need a sense of time. Maybe some situations blow out the light
+- [ ] Add attack options for most encounters. Rarely this will be a good idea though. 
+- [ ] Add a failure condition for attacking at the wrong time. Make the reasons for the failure condition contextual, for example, when they attack the stair sleeper they might trip on the stair and get injured. 
+- [ ] Add contextual awareness and autocomplete. For example a popup that appears above the USE text or when a user types "use". The user is able to autofill the rest of the thing by using the keyboard to toggle through the inv list and tab-complete the option, (or tap on mobile) "e.g. use (matches, light, letter) *on* (lamp)" - the word "on" there being suggested. Suggestions for autocomplete are in italics. This is one modern design element we're going to add.
+- [ ] Add a Notebook function. Automatically make notes as the game progresses.
+- [ ] Implement a carry mechanic. Decide whether we should have a limited carry ability (only able to carry a few things?) or we night need a full inventory system, where items are assigned to pockets or hand carry and we can only hand carry a couple of items?
+- [x] Implement a "drop" mechanic in order to drop items. Dropped items remain in the room in which they were dropped and can be picked up again.
+- [x] We need a light indicator that shows when the light is lit and how much time is left on the light. Use the svg file I dropped in the src/assets folder for the indicator. The indicator should be a 6-segment led that runs in a dotted line underneath the light indicator and burns out right to left. The color of the indicator should be bright when it's lit and dim when it's not. The indicator should be to the right of the tiles and sized appropriately.
+- [x] FEATURE: Add an option to disable the chips in the options menu.
+- [x] BUG: The new cursor doesn't appear on mobile.
+- [ ] FEATURE: Add a Safe to somewhere that it makes sense (the bedroom?) We can add a safe-cracking mini-game. The safe contains a single bullet, which can be used with the revolver. 
+- [ ] FEATURE: Add item Revolver, which can be used to kill the thing at the end. It comes with no bullets, so players need to defeat the safe-cracking minjgame. Place the revolver somewhere it takes the player some effort to find. 
+- [ ] Feature: A faceless voice that speaks in a whisper in the smoking room, which demands whiskey and dispenses riddles if the player finds a bottle of whiskey (but hasn't drunk it yet). The riddles are randomly chosen from a list of 25 difficult riddles (source them). If the riddle is answered correctly there needs to be some reward and maybe a major plot point is revealed. 
+- [x] Add item Whiskey bottle, half full of something smoky. In the kitchen. Drinking it gets the player drunk, which causes them to unlock the drunk rooms, which are a series of rooms where they can go many directions, but somehow end up in seemingly back in the same spot. They are essentially a maze of doors and hallways, ladders and levels. There should be boundaries established though, it shouldn't be endless. After 20 or so moves the player passes out and wakes up back in the foyer, with the whiskey bottle returned to the kitchen, somehow still half full. Add a random encounter in the dark rooms, a creaking floorboard helps you find a secret door that opens with a faceless man inside who gives you major plot info. After this encounter you pass out and wake up in the lobby as before. When the player is "drunk" the text on the terminal should appear blurry, like the user has double vision. 
+- [ ] Add a "Report a Bug" footer link backed by Bugpin (widget at bugpin.half.st -> forwards to GitHub Issues). Add Bugsink (@sentry/browser -> bugsink.half.st) for automatic JS error capture. Mark complete after manual verification: a test report appears in the Bugpin portal AND a GitHub issue is created AND a thrown error appears in the Bugsink portal.
+- [ ] BUG: It says the door closes behind you when you enter the lobby, but you can still exit S to the gate.
+- [x] FEATURE: Add a short "typed" effect to the text. Make it look like it's being typed out, if that makes sense, one character at a time. The effect should be brief. 
+- [x] FEATURE: Whenever you change rooms, scroll the text so the name of the room you're in is at the top. Users can scroll up to see the history. This should be an effect where the old text slides up to make room for the new text, and this should happen before the "typed" effect.
+- [ ] Open-source authoring architecture: follow [[open-source-authoring-roadmap]] to move as much story, parser, mechanic, action, and UI configuration as practical into markdown under `src/world` so authors can control it from Obsidian.

+# Authoring Halfstreet
+
+Halfstreet is authored from this `src/world` vault. The TypeScript runtime loads and validates the markdown; ordinary story changes should start here.
+
+Use wikilinks for references when you can. The loader accepts `[[foyer]]` and stores it as `foyer`, so Obsidian links stay useful without changing runtime ids.
+
+## Forking The Game
+
+The current open-source shape is a forkable Astro app. Keep `src/engine`, `src/ui`, and `src/pages` in place, then replace the markdown in this vault with your own rooms, items, encounters, endings, mechanics, actions, parser vocabulary, and UI labels.
+
+For a new game, update these files first:
+
+- `game.md`: title, starting room, starting inventory, ending priority, opening art, help text, and end text.
+- `parser.md`: direction words, verb aliases, prepositions, stop words, no-target verbs, and meta verbs.
+- `ui.md`: page title, meta description, footer labels and links, build label, and UI feature switches.
+- `templates/`: copy these starter files when adding new world content.
+
+After edits, run `npm test` from the repo root. Validation errors are meant to point back to the markdown field or section that needs fixing.
+
+## Rooms
+
+Room files live in `rooms/`. Every room needs frontmatter plus three prose sections:
+
+- `## first-visit`
+- `## revisit`
+- `## examined`
+
+Set unused exits to `null`. Set exits to `[[room-id]]` when they lead somewhere. Put item ids in `items`, and set `encounter` when a room starts an encounter.
+
+```yaml
+id: sample-room
+title: "[ Sample Room ]"
+exitN: "[[other-room]]"
+exitS: null
+exitE: null
+exitW: null
+exitU: null
+exitD: null
+items:
+  - "[[sample-key]]"
+encounter: null
+safe: true
+```
+
+Locked exits use a matching `exitXRequires` and `exitXLockedText` pair. The requirement must be an item id or a known flag.
+
+```yaml
+exitN: "[[locked-room]]"
+exitNRequires: sample-key
+exitNLockedText: The door will not move.
+```
+
+## Items
+
+Item files live in `items/`. The prose before the first `##` header is the long description shown by `examine`.
+
+Use `readable: true` only when the item has a `## read` section. Use `lightable: true` for items that can be lit, and `lighter: true` for items that can light other items.
+
+```yaml
+id: sample-key
+names: ["key", "sample key"]
+short: "a sample key"
+takeable: true
+initialState: {}
+```
+
+Allowed optional item sections are:
+
+- `## read`
+- `## lit`
+- `## extinguished`
+- `## lighter-empty`
+
+## Encounters
+
+Encounter files live in `encounters/`. Encounters are state machines: `initialPhase` points to a phase, each phase points to a description section, and each transition points to a narration section.
+
+```yaml
+id: sample-encounter
+startsIn: "[[sample-room]]"
+initialPhase: waiting
+aliases: [figure, shape]
+defaultWrongVerbNarration: wrong-verb
+phases:
+  waiting:
+    description: waiting
+    transitions:
+      - verb: wait
+        chipLabel: WAIT
+        narration: waited
+        to: resolved
+```
+
+Use `onResolved.setFlags` for flags that endings or locked exits can read. Use `requires.item` on a transition when the player must hold a specific item.
+
+## Endings
+
+Ending files live in `endings/`. `whenFlags` controls when an ending is available, and the markdown body is the ending narration.
+
+Quote ids that look like booleans:
+
+```yaml
+id: "true"
+whenFlags:
+  familySecretKnown: true
+```
+
+Bare `id: true` is parsed as a boolean by YAML before the loader sees it.
+
+## Mechanics
+
+Mechanic files live in `mechanics/`. They configure named TypeScript handlers without moving the algorithms into markdown.
+
+`mechanics/light.md` controls the light timer, burn triggers, state keys, meter setting, and fallback light prose. `mechanics/resolve.md` controls resolve levels, wrong-verb cost, safe-room recovery, and retreat behavior.
+
+Keep `handler` set to the supported handler name. Set `enabled: false` to disable a mechanic cleanly.
+
+## Actions
+
+Action files live in `actions/`. Simple actions can require visible or held items, consume inventory, decrement item state, set flags, and narrate success.
+
+```yaml
+id: sample-action
+verbs: [use]
+requires:
+  allVisibleOrHeld:
+    - "[[sample-key]]"
+setsFlags:
+  sampleActionDone: true
+```
+
+Every default action needs `## success`. Handler-backed actions may require extra sections. For example, the `drunk-transition` handler requires `## success`, `## secretFoundPassOut`, `## tooManyMovesPassOut`, and `## reset`.
+
+## Game, Parser, Messages, And UI
+
+- `game.md` controls the title, description, starting room, starting inventory, ending priority, transcript cap, opening art, help text, and ended text.
+- `parser.md` controls directions, verb aliases, prepositions, stop words, no-target verbs, and meta verbs.
+- `messages.md` controls common system prose.
+- `ui.md` controls page metadata, footer labels and links, build label visibility, and UI feature toggles.
+
+## Common Validation Errors
+
+`missing required section "## first-visit"`: add the exact section header to the room file. Section names must use only letters, digits, hyphens, and underscores.
+
+`## read section is required when readable: true`: either add `## read` to the item or remove `readable: true`.
+
+`frontmatter references missing section`: an encounter phase, transition, or failure references a prose key that does not exist. Add the section or fix the key.
+
+`exitNRequires is set but exitNLockedText is missing`: locked exits need both the requirement and locked narration fields.
+
+`references unknown item` or `references unknown room`: check the wikilink/id spelling and make sure the referenced file exists in the matching folder.
+
+`endingPriority references "true" but endings/true.md is missing`: quote boolean-like ids in YAML and make sure the ending file exists.
+
+`unknown message section` or `unknown item section`: the loader only accepts known section keys. Rename the header to one of the allowed keys for that file type.

+## watching
+One ruined portrait has not lost its eyes. The woman in it watches from behind a funeral veil, though the paint around her face has split to canvas.
+
+## examine-portraits-resolved
+You examine the portraits one by one.
+
+Damage has made a family resemblance where blood may not have. Then the veiled woman's mouth, still painted, shows you the part you did not want to see: your own expression, waiting inside hers.
+
+## wrong-verb
+The veiled portrait watches you with patient, damaged eyes.
+
+## failed
+The veil lifts though nothing touches it. You step back into the root chamber before the face beneath can finish becoming familiar.

+The basin shows no ceiling. It shows a hallway instead, and in that hallway a lamp going out.
+
+## look-resolved
+You look into the rainwater.
+
+Rooms gather there one beneath another: nursery, chapel, vault, gate. For a moment they fit together correctly. Then your reflection enters them from the wrong side, and every door in the image opens inward.
+
+When you look up, the room has learned you.
+
+## wrong-verb
+Rain touches your hands, though you are not beneath it.
+
+## failed
+The rain rises without filling the basin. You step back into the wrong hallway before it reaches your mouth.
