Subject: [PATCH 1/6] docs: rewrite course authoring guide as procedural
 LLM-facing instructions

Convert AGENTS.md prose to rules/tables and trim runtime-internal
reference (adapter spec citations, xAPI internals) that course authors
never write. 1785 -> 1502 lines; all code examples and prop tables kept.

 # AGENTS.md: Tessera Course Authoring Guide
 
-Tessera is an **LMS tracking runtime** for interactive learning content. It handles SCORM 1.2 / SCORM 2004 / cmi5 / xAPI statements, progress state, completion and success rollup, persistence, and navigation gating, and gets out of the way for the presentation layer.

 ```
 
-The dev server hot-reloads as you edit pages, layouts, components, and `course.config.js`. The `export` command produces a SCORM 1.2, SCORM 2004, cmi5, or static-web bundle depending on `course.config.js`.
-
-`pnpm validate <course>` runs the same checks as `dev` and `export` (page syntax, manifest shape, `pageConfig`, question components, asset references, LMS data-contract bypass, and the static accessibility rules) and exits non-zero if any fail. Use it as a fast feedback loop after editing — it's the quickest way to confirm a change is structurally sound.
-
-`pnpm check <course>` runs `validate` and then the deeper, opt-in pass (`tessera a11y`): it builds the course, renders every page in a headless browser, and runs [axe-core](https://github.com/dequelabs/axe-core) to catch issues a static scan can't see (computed ARIA, real rendered contrast). The runtime audit drives Playwright; the first run installs the Chromium browser automatically if it's missing. See [Accessibility](#accessibility).
-
-`dev`, `export`, `validate`, and `check` are **reserved script names** — each is a thin alias for the matching `tessera` subcommand. Don't repurpose them.

-The framework owns the build (there is no `vite.config.js`), the reserved scripts, and this authoring guide, so nothing in your tree needs reconciling. This guide ships _inside_ `tessera-learn` (you're reading `node_modules/tessera-learn/AGENTS.md`), so bumping the dependency updates it automatically.

-Tessera runs Vite for you with the right plugins; you never write a `vite.config.js`. If you genuinely need to extend the build, add a `tessera.config.js` at the project root. It is a **partial** Vite config that Tessera merges on top of its own — you only specify the delta, and `tesseraPlugin()` (with the Svelte compiler) stays wired in automatically:

-

+### Editing rules
 
-**Never edit `node_modules/`.** `node_modules/tessera-learn/` is the framework itself — edits there are git-ignored, work only until the next `pnpm install`, and are silently wiped when the course's tessera-learn version is updated. (There is no `vite.config.js` to edit either; the build is the framework's. For a genuine build tweak, add a `tessera.config.js` — see [Customising the build](#customising-the-build-optional).) If you think you need to change framework behaviour, you're looking for an extension point instead:
+- **Edit freely:** `pages/`, `course.config.js`, `layout.svelte`, `quiz.svelte`, custom components, `assets/`, `styles/`.
+- **Never edit `node_modules/`.** Edits there are git-ignored and wiped on the next install/update. There is no `vite.config.js` to edit.
+- To change framework behaviour, use an extension point instead of patching `node_modules/`:
 
-- **New question type or interactive widget** → a custom component using the `useQuestion` hook.
-- **Different course chrome** (header, nav, layout) → `layout.svelte`.
-- **Different quiz UI** → `quiz.svelte` using the `useQuiz` hook.
-- **Styling** → `styles/`.
-- **Navigation, completion, scoring, or export target** → `course.config.js`.
+| Need | Use |

+| Different quiz UI | `quiz.svelte` with the `useQuiz` hook |
+| Styling | `styles/` |
+| Navigation, completion, scoring, export target | `course.config.js` |
 
-If none of those fit, the limitation is real — surface it rather than patching around it in `node_modules/`.

 ### Hierarchy and ordering
 
-The manifest is always **section → lesson → page**. Files directly in a section folder are flattened into one implicit lesson with the section's title; lesson subdirectories nest as expected. Both shapes can coexist.
+- Manifest is always **section → lesson → page**. Files directly in a section folder flatten into one implicit lesson titled after the section. Lesson subdirectories nest. Both shapes can coexist.
+- Sorting is alphabetical by directory/filename.
+- Numeric prefixes on directories (`01-`, `02-`) set explicit order and are stripped from slugs/titles (`01-getting-started/` → slug `getting-started`, title "Getting Started").
+- Control page order **within a lesson** with `_meta.js`, not filename prefixes.
 
-Sorting is alphabetical by directory / filename. Numeric prefixes on directories (`01-`, `02-`, …) give explicit ordering without renaming the files inside, and are stripped from slugs and titles (`01-getting-started/` → slug `getting-started`, title "Getting Started").

+### `_meta.js`
 
-### `_meta.js` files

-**Optional everywhere.** When absent, titles fall back to the title-cased slug (`01-getting-started/` → "Getting Started") and pages sort alphabetically by filename. **Omit the file entirely** when those defaults are what you want — `pages: ["only-page"]` on a single-page lesson is a no-op, and `title: "Splash"` on `01-splash/` duplicates the auto-derived title.
-
-Reach for `_meta.js` only when the override is real:
+Use it only for a real override:
 
 ```js
-// section or lesson _meta.js: title override (folder name doesn't auto-derive to what you want)
+// title override (folder name doesn't derive to what you want)
 export default { title: 'How to play' }; // folder is `01-intro`
 ```
 
 ```js
-// lesson _meta.js: explicit page order
-export default {
-  title: 'Welcome',
-  pages: ['welcome', 'objectives'],
-};
+// explicit page order — listed pages first, unlisted .svelte appended alphabetically
+export default { title: 'Welcome', pages: ['welcome', 'objectives'] };
 ```
 
-Pages listed in `pages` come first in listed order; any unlisted `.svelte` files are appended alphabetically.

-2. **Hooks**: `useQuestion`, `useQuiz`, `useNavigation`, `useProgress`, `useCompletion`, `usePersistence`. The stable contract between custom widgets and the runtime. Anything the built-ins do, you can do.
-3. **Custom layout**: drop `layout.svelte` at the project root to replace the default chrome.
-4. **Custom quiz shell**: drop `quiz.svelte` at the project root to replace the built-in quiz UI for every page that has `pageConfig.quiz`. Authors call `useQuiz()` for state and dispatch; question widgets continue to register through `useQuestion`.
-5. **Custom xAPI**: `useXAPI()` returns a publisher for emitting your own xAPI verbs to one or more LRSes. See [Custom xAPI statements](#custom-xapi-statements).

-### Data contract: what the LMS sees
+### Data contract
 
-Whatever quiz UI you build, the LMS sees the same `cmi.interactions` it would from the built-in: every question registered through `useQuestion` flows through the persistence adapter. Each interaction is reported the moment the widget calls `q.commit()` — atomic widgets (MCQ, true-false, likert) call it on click, composite widgets (matching, sorting, fill-in) call it on blur or final-state. `useQuiz().submit()` calls commit on any question whose widget hasn't yet, as a safety net. The reporting cost — one xAPI Answered / one `cmi.interactions.n` block per call — happens incrementally throughout the session rather than batching at the end, so a learner closing the tab after the last commit still gets credit. Bypass `useQuestion`/`useQuiz` and the quiz reports nothing.

 ### Per-question weighting
 
-Pass `weight` to `useQuestion` (and through built-in widget props) to change how much a question pulls on the page-level score. Defaults to 1; non-positive values are treated as 1.
+Pass `weight` (default 1; non-positive treated as 1) to change how much a question pulls on the page score. Works identically inside `<Quiz>` and standalone.
 
 ```svelte
 <MultipleChoice id="q-easy" weight={1} ... />
 <MultipleChoice id="q-hard" weight={3} ... />
 ```
 
-Weights apply identically inside a `<Quiz>` and to standalone questions on a plain page — the same widget answered the same way produces the same page score either way.
-
-The page-level score is the weighted-correct percentage: `Σ(weight × correct) / Σ(weight) × 100`, rounded. With every weight at the default 1 this is the plain correct-count percentage.
-
-The LMS still sees each question as a single pass/fail interaction; weights only affect the page-level `cmi.core.score.raw` rollup, not `cmi.interactions.*`.

 ## Manual completion
 
-`completion.mode: "manual"` is for courses where the author — not a quiz score or a page-visit ratio — owns the moment of completion. Two examples:
-
-- A short policy briefing where reading the final page **is** the proof of completion.
-- A compliance "click to acknowledge" button at the end of a module.

-- Combining manual + quiz/percentage rules ("complete when X **and** quiz passed"). Use a `useCompletion()` call inside a custom `$effect` if you need conditional logic.
-- Per-learner conditional completion expressed in config — same answer: do it in a component with `useCompletion()`.
-- Marking a course **incomplete** after it has been completed. Completion is monotonic in every spec we target. The runtime ignores re-marks.

 ## Accessibility
 
-Tessera checks accessibility in two passes, plus components that are accessible by construction.
-
-**Static checks** run inside `validate`, `dev`, and `export` — no extra setup. They cover what's visible in your source: `<Image>` alt-or-`decorative`, `<Video>`/`<Audio>` `title` + captions/transcript, empty question option/answer labels, skipped heading levels (e.g. `h2` → `h4`), `branding.primaryColor` contrast against white, and a well-formed `language` tag. They also route the Svelte compiler's own `a11y_*` warnings through the reporter. Each diagnostic carries a rule ID in brackets (e.g. `[tessera/image-alt]`, `[a11y_missing_attribute]`) — that ID is what `a11y.ignore` and `a11y.level` match.
+Two passes plus components that are accessible by construction.
 
-**Runtime audit** is the opt-in deep pass: `pnpm a11y <course>` (run it directly, or via `pnpm check <course>`, which runs `validate` first) builds the course, renders **every** page in a headless browser (including pages gated behind a quiz), runs [axe-core](https://github.com/dequelabs/axe-core), writes `a11y-report.json`, and exits non-zero on any violation at or above an impact threshold (default `serious`). It catches what a static scan can't — computed ARIA, focus order, real rendered contrast.

-The audit renders the course with the web adapter, so it works regardless of your `export.standard` — you don't need an LMS to run it.
-
-The audit's ruleset and severity come from the `a11y` block in `course.config.js` (`standard`, `ignore`); see [`course.config.js`](#courseconfigjs). `a11y-report.json` is build output — it's git-ignored by default.
+It builds the course, renders **every** page headless (including quiz-gated pages), runs [axe-core](https://github.com/dequelabs/axe-core), writes `a11y-report.json` (git-ignored), and exits non-zero on any violation at/above the impact threshold (default `serious`). It catches what a static scan can't: computed ARIA, focus order, rendered contrast. First run auto-installs Chromium. It uses the web adapter, so it works regardless of `export.standard`.
 
-Hard contract errors (missing `alt`, missing media `title`) always block the build. Everything else is a warning unless you set `a11y.level: "error"`. To silence a specific rule everywhere, add its ID to `a11y.ignore`.

-   ```
-   The `account` IFI satisfies xAPI's Identified Agent rule. `homePage` defaults to the activityId origin; override via `actorAccountHomePage` if your authority namespace is elsewhere. Required if `activityId` is a non-URL IRI.
-4. **Fallback: error.** Web export with no `actor` fails at config time.
+### Gotchas
 
-Mid-session identity change (e.g., learner logs in/out without reloading) is **not supported in v1**. Actor is resolved once per page-load and cached. Reload the runtime on identity change.
-
-### Auth
-
-v1 supports **Basic auth only**. The publisher prepends `Basic ` to whatever your `auth` value resolves to; pass the credential value, not the full header.
-
-For OAuth-protected LRSes, wrap the token exchange in your `auth` function and return a Basic credential the LRS accepts (or run a thin proxy that converts).
-
-The function form is re-invoked once on a 401 to cover short-lived tokens that have just expired. Two consecutive 401s mark the auth resolver dead for the publisher's lifetime. Every subsequent send fails fast without hitting the LRS. Reload the runtime to retry.
-
-**Static-string `auth` ships in your bundle**: fine for demos, never for production. Use a function that fetches a server-brokered short-lived token instead.
-
-### Retry policy
-
-- **Default:** 3 attempts with exponential backoff (100ms, 200ms, 400ms).
-- **5xx / network errors** retry. **4xx** short-circuits; retrying won't help.
-- **HTTP 409 Conflict** is treated as **success** (xAPI rejects POSTs with a duplicate statement id, so a 409 on retry means the LRS already accepted the statement).
-- **Per-statement opt-out:** `sendStatement(stmt, { retry: false })` for fire-and-forget telemetry where the author would rather drop than block.
+- **Actor priority:** author-supplied `xapi.actor` always wins; else cmi5 launch actor; else SCORM-derived from the LMS data model; else error. Override the SCORM-derived `homePage` via `actorAccountHomePage` (required if `activityId` is a non-URL IRI).
+- **Auth is Basic-only.** Pass the credential value, not the full header (the publisher prepends `Basic `). For OAuth, return a Basic credential from your `auth` function or run a proxy.
+- **Never ship a static `auth` string on web** — the bundle is public. Use a function that fetches a server-brokered short-lived token. CORS must allow the served origin.
+- **`actor` is required on web export** and resolved once per page-load (no mid-session identity change in v1 — reload to switch).
+- **Page unload rejects sends.** Once unload begins, `sendStatement` rejects (keeps cmi5 Terminated last). Do end-of-session work in a child component's `onDestroy`, not `beforeunload`.
+- **Retry:** 3 attempts, exponential backoff; 5xx/network retry, 4xx short-circuits, 409 treated as success. Opt out per call with `sendStatement(stmt, { retry: false })`.
 
 ### `sendStatement` return shape
 
 ```ts
 const result = await xapi.sendStatement({ verb, object });
-// result: {
-//   statementId: string,
-//   statement: Statement,           // fully resolved: actor, context, timestamp filled in
-//   destinations: [{ endpoint, ok, status?, error? }, ...]
-// }
+// { statementId, statement, destinations: [{ endpoint, ok, status?, error? }, ...] }
 ```
 
-`destinations[]` lets you act on partial failures under fan-out: one LRS can be down without affecting the others.
-
-### Validation
-
-The publisher checks three things before sending:
-
-1. `verb.id`: present, non-empty string.
-2. `object.id`: non-empty string when `object` is supplied.
-3. `result.score.scaled`: number in `[-1, 1]` when supplied.
-
-Everything else passes through. The LRS gives clearer errors for IRI / extension / attachment shape issues than we can; failures surface via `destinations[].error`.
-
-### Mode-specific caveats
-
-**SCORM (1.2 / 2004).** Actor is auto-derived from the LMS data model; supply `actor` explicitly to use a different IFI (`mbox`, `openid`). **CORS** is the painful one: the LRS must allow the LMS-served origin, and many don't by default. cmi5's `sessionid` extension does not exist here; attach your own extension if you need to group statements by session. In dev (WebAdapter fallback), an explicit `xapi` destination with no author actor cannot synthesize an Agent, so `sendStatement` rejects with an explicit error.
+`destinations[]` lets you handle partial failures under fan-out. The publisher validates only: `verb.id` non-empty, `object.id` non-empty when supplied, `result.score.scaled` in `[-1, 1]` when supplied. Everything else passes through; the LRS reports shape errors via `destinations[].error`.
 
-**Web.** The bundle is public, so static `auth: 'Basic abc123'` leaks. Always use a function that fetches a server-brokered short-lived token. CORS matters for the token endpoint too. Three actor patterns: hardcoded anonymous, author-wired (`actor: () => getCurrentUser()`), or query-string `?actor=...` mirroring cmi5.
+### Not in v1
 
-**cmi5 with `endpoint: 'lms'`.** Author and adapter share one publisher instance and one queue, so ordering is preserved (no race between an author's `experienced` and the adapter's `Completed`). Running locally without launch params, `sendStatement` rejects with a missing-params error. No silent fallback. Point `endpoint` at a local LRS for dev.
-
-**Page unload.** Once unload begins, every publisher is marked unloading and `useXAPI()?.sendStatement(...)` calls reject; this is required to keep cmi5 Terminated last on the wire (§9.3.6). Record-at-the-end work belongs in a child component's `onDestroy`, not `beforeunload`.
-
-### Non-goals (v1)
-
-- Bearer / OAuth credentials at the publisher level (wrap in your `auth` function).

-
-The SCORM adapter's internal `commit()` (the `LMSCommit` / `Commit` call) is microtask-coalesced — multiple state mutations within one tick collapse to a single API call. cmi5 statements are individual (no batched commit).
-
-### SCORM 1.2 notes
-
-API discovery: walks `window.parent` / `window.opener` up to 10 levels looking for `API`.
-
-**One status field.** `cmi.core.lesson_status` collapses completion and pass/fail. The runtime resolves them by priority: success (`passed` / `failed`) wins when known; otherwise completion (`completed` / `incomplete`) is written. There is no "unknown"; until a graded quiz produces a result, the LMS sees `incomplete`.
-
-**Mastery is Tessera's, not the LMS's.** Pass/fail is computed from `scoring.passingScore`. `cmi.student_data.mastery_score` is read-only for this runtime.
-
-**Interaction encoding (§3.4.7).** Plain `,` items, `.` pairs, `:` ranges (not the bracketed `[,]` 2004 form). `cmi.interactions.n.id` and response/correct identifiers are slugged to `CMIIdentifier` (alphanumeric + underscore, max 250 chars) — raw option text like `"88 Earth days"` becomes `88_Earth_days`, and an id like `q-1` becomes `q_1`, to dodge `405 Incorrect Data Type`. `true-false` writes `t`/`f`. Numeric `correct_responses.n.pattern` is a single CMIDecimal; ranges are dropped (`result` still carries pass/fail).
-
-**Field write order.** `id` → `type` → `correct_responses.0.pattern` → `student_response` → `result` → `time`, matching the spec's `interactions._children` ordering. SCORM Cloud's strict validator rejects `student_response` with the misleading "must be consistent with interaction type" if `correct_responses.0.pattern` hasn't been declared first — the LMS has no expected pattern to validate against. Other LMSes (Moodle, Reload, scorm-again) accept any order, but the spec ordering is the safest.
+## LMS behaviour
 
-**Bookmark.** `cmi.core.lesson_location` is written from `SavedState.b` on every `saveState` to surface "Resume from page N" in LMS UIs.
+The runtime translates author intent into adapter calls automatically; you don't write any of it. The author-relevant differences:
 
-**Not implemented.** No `cmi.objectives.*` writes. No SCORM 1.2 sequencing; `navigation.canAccess` is the only gating layer, and the LMS sees one SCO. SCORM 1.2 `time-out` / `logout` exit values are not emitted.
+| Concern                | SCORM 1.2                                  | SCORM 2004 4th                          | cmi5                                  |
+| ---------------------- | ------------------------------------------ | --------------------------------------- | ------------------------------------- |
+| Completion + success   | One field (`lesson_status`); no "unknown" — success wins when known, else completion | Two independent fields (`completion_status`, `success_status`) | Completed + Passed/Failed statements |
+| Score scale to LMS     | `score.raw` (0–100)                        | `score.raw` (0–100) **and** `score.scaled` (0–1) | `result.score.scaled` (0–1)    |
+| `usePersistence` cap   | ~4 KB (plan for 4096 chars)                | 64000 chars                             | LRS-defined (typically unbounded)     |
+| Resume after reload    | From `cmi.suspend_data`                    | From `cmi.suspend_data`                 | From `tessera-state` (State API)      |
 
-**Local testing.** Upload `dist/*-scorm12.zip` to [SCORM Cloud](https://cloud.scorm.com) (free tier) or [Reload SCORM Player](https://github.com/reload/reload). Inspect the LMS API call log to confirm `lesson_status` and `cmi.interactions.*` look right.
+Author-facing consequences:
 
-### SCORM 2004 4th notes
+- **Keep persisted state small under SCORM 1.2** — it shares the ~4 KB `suspend_data` budget with progress and bookmarks.
+- **SCORM 1.2 shows `incomplete` until a graded quiz produces a result** (no "unknown" status). Pass/fail uses `scoring.passingScore`, not the LMS's mastery field.
+- **SCORM 2004 / cmi5 honor an LMS-supplied mastery score** at launch, overriding `scoring.passingScore`. Read it via `useQuiz().passingScore`.
+- A failed `adapter.init()` renders a visible "This course can't run here" panel — never a silent degradation.
 
-API discovery: `API_1484_11` via the same parent/opener walk.
+### Local testing
 
-**Two status fields, both written.** `cmi.completion_status` and `cmi.success_status` are independent. `unknown` is written _explicitly_ when no graded result exists; leaving it null causes some LMSes (notably SCORM Cloud) to roll a null up to `passed` during status rollup.
+| Standard   | How to test                                                                                  |

-**LMS-supplied thresholds.** `cmi.scaled_passing_score` (§4.2.4.3) is read on init and exposed via `adapter.getMasteryScore()`. `App.svelte` picks up `masteryScore` and overrides `scoring.passingScore` for the launch — parity with cmi5's launch-time mastery.
-
-**Launch mode (§4.2.1.5).** `cmi.mode` is read on init. In `browse` and `review` launches every learner-record write is silently suppressed (`setScore` / `setCompletionStatus` / `setSuccessStatus` / `setExit` / `setDuration` / `reportInteraction` / `saveState` — including the `cmi.suspend_data` write). Mirrors cmi5's launchMode handling; exposed via `adapter.getLaunchMode()`.
-
-**Interaction encoding (§4.2.7 / Appendix A).** Bracketed delimiters `[,]` / `[.]` / `[:]` (literal text, not regex). Identifiers are passed through unchanged — §4.2.7 / Appendix A's `short_identifier_type` allows any printable, and 2004's `cmi.interactions.n.id` upgraded to `long_identifier_type` (4000 chars). Slugging would only obscure LMS-side reports without buying anything. `cmi.interactions.n.timestamp` is `time(second,10,0)` per §3.3.10.1 / ISO 8601 §5.3.3 — zone-free, second-resolution (`YYYY-MM-DDThh:mm:ss`); SCORM Cloud rejects fractional seconds and `Z` / `±hh:mm` suffixes with 406.
-
-**Bookmark + progress.** `cmi.location` is written from `SavedState.b` on every `saveState`. `cmi.progress_measure = 1` fires on `setCompletionStatus('complete')` so LMS dashboards show 100%.
-
-**Real precision.** All CMIDecimal-like writes (`score.raw`, `score.scaled`, etc.) round through `formatReal107` — SCORM 2004 4E defines them as `real(10,7)`, and `String(1/3)` would otherwise trip 406.
-
-**Not implemented.** `imsss:sequencing` rules are omitted from `imsmanifest.xml` by design. No `cmi.objectives.*`, no `cmi.adl.nav.*` writes.
-
-**Local testing.** SCORM Cloud is the easiest end-to-end check. Moodle, Cornerstone, SuccessFactors, and Canvas (via Rustici Engine) accept `dist/*-scorm2004.zip` directly.
-
-### cmi5 notes
-
-**Launch contract.** The LMS opens the course URL with `endpoint`, `fetch`, `actor` (JSON-encoded Identified Agent), `activityId`, and optionally `registration`. Discovery succeeds when all four required params are present; otherwise `LMSAdapterError`.
-
-**Token fetch is single-use** (cmi5 §6.2). On failure, reload from the LMS to retry. The token is used as a `Basic` credential, not Bearer. If the fetch URL responds with the spec-defined `{"error-code":...,"error-text":...}` shape (§8.2.3 — typically the single-use violation on a refresh), `adapter.init()` throws with the LMS's error-code/text instead of stuffing the JSON blob into the `Basic` credential and 400-spamming the LRS.
-
-**Lifecycle order.** **Initialized** → **Answered** (one per question, as each widget calls `q.commit()`; uncommitted ones flush at submit) → **Completed** → **Passed** / **Failed** → **Terminated** (always last, cmi5 §9.3.6). Completed is one-shot per registration (never re-emitted on resume); Passed/Failed are re-emitted only on a _status transition_ (e.g., a learner who failed in session 1 and passes in session 2 fires a fresh Passed in session 2, but a learner who passed before and resumes does not re-emit). The runtime seeds the adapter at restore time via `seedLifecycle()` so the LMS isn't spammed with duplicates that 403 as "completion status already determined." **Satisfied** and **Suspended** are not emitted by the AU — Satisfied is LMS-only (§9.3.9), and Suspended isn't a cmi5 verb (§9.3 enumerates nine; the LMS handles Abandoned / resume on relaunch).
-
-**Required result fields.** Completed: `completion: true`, `duration` (no `score` — §9.5.1 forbids it). Passed: `success: true`, `duration`, `result.score.scaled` when known (§9.3.4 requires `scaled >= masteryScore` when present). Failed: `success: false`, `duration`, `result.score.scaled` when known (§9.3.5 requires `scaled < masteryScore` when present). Terminated: `duration` (§9.5.4.1). On contradiction the verb is preserved and the score is dropped with a console warning.
-
-**Context per Defined Statement.** Categories: `cmi5` Category Activity on every Defined Statement (§9.6.2.1); plus `moveOn` Category on Completed / Passed / Failed (§9.6.2.2). Extensions: `sessionid` (§9.6.3.1) on every statement (Defined and Allowed) — value sourced from `LMS.LaunchData.contextTemplate` when supplied, else minted UUID. `masteryScore` extension on Passed / Failed only (§9.6.3.2). The full `contextTemplate` from `LMS.LaunchData` is merged in (§9.6.2 makes it the AU's base context; §10.2.1 says AU MUST NOT overwrite template values, so the AU's categories are concatenated and deduped against the template's, never replacing them).
-
-**`LMS.LaunchData` (§10).** Fetched once at init from the State API under `stateId='LMS.LaunchData'`. The AU reads `contextTemplate`, `launchMode`, `returnURL`, and `masteryScore` from it. LaunchData values override anything parsed from the launch URL (§10.2.4 makes LaunchData authoritative). When the document is absent, statements ship without the LMS-supplied Publisher Activity and may be rejected by strict LRSes — a console warning fires.
-
-**Learner Preferences (§11).** `cmi5LearnerPreferences` from the Agent Profile API, fetched _before_ Initialized — strict LRSes (SCORM Cloud) track that the GET happened and reject Initialized otherwise. A 404 here is normal (no preferences set); only the GET itself is required, and the response body is not consumed.
-
-**Launch mode (§10.2.2).** "Normal" launches emit the full lifecycle. "Browse" and "Review" launches emit only Initialized and Terminated — every other Defined Statement is silently suppressed. Exposed via `adapter.getLaunchMode()`.
-
-**Return URL (§10.2.6).** `adapter.exit()` is the explicit-exit path: calls `terminate()`, awaits the publisher queue so Terminated lands before navigation, then `window.location.assign(returnURL)`. The page-unload `terminate()` path can't redirect (the browser is already navigating).
-
-**State persistence.** `tessera-state` document via the State API, keyed by `activityId` + `agent` + `registration?` + `stateId='tessera-state'` (distinct from the LMS-owned `LMS.LaunchData` and `cmi5LearnerPreferences` documents). Writes chain onto the publisher's queue so the suspend payload lands before Terminated.
-
-**Manifest (`cmi5.xml`).** Generated by the plugin: course id + AU id are stable URNs derived from `config.title` (`urn:tessera:{course,au}:<hex>`). `<au>` carries `launchMethod="AnyWindow"` (CourseStructure XSD requires it), `moveOn` (`Completed` for percentage/manual, `CompletedAndPassed` for quiz mode), and `masteryScore` (rounded to 4 decimal places per §10.2.4). The `<url>` is a child element of `<au>`, not an attribute.
-
-**Not implemented.** No multi-AU courses (one course = one AU in v1). No **Waived** or **Abandoned** verbs (LMS-only). No mid-session actor refresh.
-
-**Local testing.** Upload `dist/*-cmi5.zip` to SCORM Cloud and use the cmi5 dispatch URL it generates, the closest free equivalent to a real LMS launch.
-
-### Common adapter behaviour
-
-**Queue + retry.** SCORM adapters serialize every `LMSSetValue` / `LMSCommit` through a sequential queue with exponential-backoff retry on transient errors. Each enqueue carries the cmi key as `context`; retry warnings include the real LMS error code (`GetLastError`), the message (`GetErrorString`), and — when supplied — the verbose diagnostic (`GetDiagnostic`, which SCORM Cloud uses to name the offending element). The give-up log reads e.g. `[cmi.interactions.0.timestamp] (LMS error 406: Data Model Element Type Mismatch — is not a valid time type)`.
-
-**Init / terminate logging.** `Initialize` failures fire a top-level warning that names the LMS error code and notes downstream writes will all 301. Malformed `cmi.suspend_data` and non-numeric `cmi.interactions._count` are logged loudly — the latter is dangerous to silently fall back to 0 (the next session would overwrite prior records). Terminate-path `Commit` / `Terminate` / `LMSFinish` failures route through `callSyncOrWarn` so the last-chance writes aren't silent.
-
-**Unload.** `terminate()` cannot run async retries; the page is going away. SCORM drains the queue synchronously (single attempt per pending op) before `Commit` + `Terminate` / `LMSFinish`. cmi5 marks the publisher unloading and uses `keepalive: true` so the browser does not cancel in-flight statements.
-
-**Failure surface.** Anything thrown from `adapter.init()` is caught by `App.svelte` and rendered as a visible "This course can't run here" panel. Never a silent degradation.
+Inspect the LMS API call log to confirm `lesson_status` / `completion_status` / interactions look right.

Subject: [PATCH 4/6] docs: fix tessera-learn README pointer to the authoring
 guide

The GitHub link resolved to the root monorepo dev guide; point it at
packages/tessera-learn/AGENTS.md. Correct the "guide at the workspace
root" wording to reflect the pointer model, and add the missing
useCompletion hook to the included-hooks list.

Subject: [PATCH 5/6] docs: align a11y invocation in the guide with the
 scaffolded script

The rewrite documented the runtime audit as `pnpm exec tessera a11y`,
but the scaffolded workspace exposes a `pnpm a11y <course>` script and
the workspace README already uses that form. Switch the guide to
`pnpm a11y <course>` and list a11y among the reserved script names so
all the authoring docs agree.

 - `validate` runs the same static checks as `dev`/`export` and exits non-zero on failure. Use it as the fast feedback loop after editing.

 It builds the course, renders **every** page headless (including quiz-gated pages), runs [axe-core](https://github.com/dequelabs/axe-core), writes `a11y-report.json` (git-ignored), and exits non-zero on any violation at/above the impact threshold (default `serious`). It catches what a static scan can't: computed ARIA, focus order, rendered contrast. First run auto-installs Chromium. It uses the web adapter, so it works regardless of `export.standard`.
