Theme the sidebar scrollbar

The screenshot section had been a placeholder since the shell was rebuilt as
three panes, because there was no cheap way to re-shoot and a stale image is
worse than no image. So this ships the capture, not just the captures:
scripts/screenshots.mjs takes all ten pages at 1440x900 and 393x852, in light
and dark, and screenshots-encode.py halves and re-encodes them to WebP — 16MB
of PNG becomes 1.9MB in the tree.

Two things would silently ruin a run, and the script exists to encode both.
Seeding localStorage['pig.themeMode'] is not enough: the appearance preference
is authoritative server-side and adopted after hydration, so every dark capture
snapped back to light a beat after first paint. The /api/me/profile response is
rewritten instead. And pig.sidebarOpen / pig.piggyDockOpen are per-device, so
whatever the last human left behind would otherwise leak in. The run also fails
on a wrong theme, a horizontal scrollbar or a console error — three things a
screenshot cannot show you.

Piggy is not pictured mid-conversation. It is off by default and no inference
credential exists, so such an image would be a staged transcript rather than a
capture. The README says that rather than implying the feature is missing.

Correcting what the README asserted while shooting against the running code:
read authorisation IS enforced — createReadGuardRoutes is mounted ahead of the
feature routes, and routes/learn.ts and routes/activities.ts are mounted too,
so only the HubSpot pair is still unreachable. The remaining read gap is that a
grant cannot be narrowed, there being no row-level team filter in the query
layer. Counts refreshed against the tree: 275 tests, ~47k lines, 14 migrations.

+(the RBAC model) and `apps/api/src/lib/mutation.ts` (the write path) — are
+settled; read them before adding any write.
 
-**Do these first, alone, before anything fans out:**
+**The highest-value work now, in order:**
 
-- **F1** — install the shadcn primitive set

-- **F3** — the RBAC permission model
+   written, tabulated and tested, and does nothing, because `app.ts` never
-- **F2** — the shared API write-path convention (needs F3 to call into)
+   mounts it. Until it does, every authenticated member can read supplier cost
+   and margin. It is one line, and it must be registered *before* the handlers
+   it guards — Hono runs matched handlers in registration order.
+2. **Mount `learn.ts`.** `/learn` is in the navigation and its API answers 404.
+3. **Enqueue the other six agent task kinds.** The worker is complete; only
+   `enrich_account` and `enrich_contact` are ever written to `agent_tasks`, so
+   Piggy does far less than the ontology implies.
+4. **Mount the HubSpot routes, or delete them.** Seven tables, OAuth, sync jobs
+   and webhook verification, all written, tested and unreachable.

+Piggy is deliberately not pictured mid-conversation. It is off by default
+(`PIGGY_ENABLED=false`, and the Compose service sits behind a profile), and
+showing it answering would mean staging a transcript rather than capturing one.
+What it may and may not do is described under [the agent
+surface](#the-agent-surface).
+
+## The two-sided data model
+
+Forty-seven tables, but the shape is small. These are the ones that carry the
+thesis:
+
+| Table | What it holds | Why it is not in a generic CRM |
+|---|---|---|
+| `capacity_commitments` | What you bought: term, GPU-hours, cost per GPU-hour, floor and ceiling, and a **shape** (`{intervals[], quantities[]}`) | Real contracts ramp across tranches and step down at checkpoints; a single start/end/total reports availability that does not exist in the month someone wants it |
+| `demand_deals` | What you are selling: ACV, product line, MSA/DPA state, stage | The paper state is a separate axis from the stage, because paper gates delivery |
+| `supply_deals` | The other pipeline: sourcing a provider through diligence to live | Generic CRMs have one pipeline and call the supplier a vendor |
+| **`allocations`** | **The join.** Commitment × deal × GPU-hours × window × status | This is the whole product. Margin, utilisation and idle all derive from it |
+| `inventory_listings` | Market availability mirrored from the Prime Intellect API | Sync is a straight field mapping, not an ETL project |
+| `capacity_requests` | What a customer asked for, whether or not it could be served | Unservable demand is the signal for what to buy next |
+| `contracts` + `sla_terms` + `sla_metric_targets` + `contract_obligations` | Polymorphic over party and type — MSA, DPA, SLA, order form, capacity commitment — with negotiated SLA terms and dated obligations | The supply side negotiates heavyweight paper; the self-serve demand side runs on a reliability tier and a credits policy instead |
+| `export_authorizations`, `compliance_artifacts`, `compliance_decisions` | Export-control determinations recorded **on the allocation edge**, with reasoning and rule version | US controls apply an ultimate-parent test that reaches through the corporate tree, so country of incorporation is not a valid key |
+| `facts` | Every agent-derived claim, with score, band, evidence excerpt and source URL | An agent allowed to write unattributed claims will eventually write a wrong one and nobody will be able to tell which |
+| `agent_tasks` / `agent_runs` / `agent_actions` | The queue the API writes to and the agent drains, plus what it did | The API never calls the model; it writes a row |
+
+Two pipelines, with stages taken from how the market operates:
+
+```
+Demand:  qualification → legal → scoping → proposal → procurement
+         → POC → deployment → expansion            (+ closed_won / closed_lost)
+
+Supply:  sourced → qualifying → technical diligence → financial diligence
+         → pricing → contracting → onboarding → live → renewal
+                                                 (+ churned / rejected)
+```
+
+**Legal sits second** in the demand pipeline. MSA and DPA execution gates the
+deal rather than closing it. Most CRMs put contracts at the end of the funnel
+and are wrong about it for this market.
+
+Three further decisions worth knowing before you read the schema:
+
+- **Holds reserve; they do not sell.** A live hold removes capacity from
+  everyone else's availability — otherwise two sellers promise the same GPUs —
+  but never counts toward utilisation or revenue.
+- **Security tiers are ranked, not labelled.** `community_cloud` <
+  `secure_cloud` < `government`, and a requirement is satisfied only from at or
+  above its tier.
+- **Money is integer cents**, rounded exactly once, at the boundary.
+
+## Self-hosting
+
+### Requirements
+
+Node 22+, pnpm 11+ (pinned by `packageManager`; `corepack enable` installs it),
+and a PostgreSQL 16 database that PIG owns exclusively.
+
+### Development
+
+```bash
+corepack enable
+pnpm install
+
+docker run -d --name pig-dev -p 5432:5432 \
+  -e POSTGRES_USER=pig -e POSTGRES_PASSWORD=pig -e POSTGRES_DB=pig \
+  postgres:16-alpine
+
+export DATABASE_URL=postgres://pig:pig@localhost:5432/pig
+pnpm run db:migrate
+pnpm run db:seed     # optional — sourced, cited, confidence-graded people
+pnpm run db:demo     # optional — a plausible demo book, prefixed "DEMO — "
+
+pnpm run dev:api     # :8920
+pnpm run dev:web     # :5173, proxies /api to :8920
+```
+
+With no identity provider configured, **authentication is disabled in
+development** and every request runs as the first user in the table.
+`loadConfig` refuses to start with `NODE_ENV=production` in that state, so it
+cannot leak into a deployment.
+
+### Production
+
+```bash
+cp .env.example .env    # then edit
+docker compose -p pig up -d db
+docker compose -p pig run --rm --no-deps app pnpm exec tsx packages/db/src/migrate.ts
+docker compose -p pig up -d --build app
+```
+
+Migrate from a one-off container **before** the app starts, not with `exec`: a
+release that queries a table its migration has not yet created crash-loops
+before you can attach to it. Full deployment notes, including the reverse
+proxy, the release poller and rollback semantics, are in
+[`deploy/README.md`](./deploy/README.md).
+
+### Every environment variable
+
+Read from `apps/api/src/lib/config.ts` (API), `apps/piggy/src/config.ts`
+(Piggy) and `docker-compose.yml`. **Bold** means no default.
+
+#### Required
+
+| Variable | Default | Notes |
+|---|---|---|
+| **`DATABASE_URL`** | — | The only unconditionally required value. PIG owns this database exclusively |
+| **`POSTGRES_PASSWORD`** | — | Compose only; `docker-compose.yml` refuses to start without it |
+
+In production you must additionally set **either** `SUPABASE_URL` **or**
+`PIG_OIDC_ISSUER`. The API throws at boot with neither.
+
+#### Identity
+
+| Variable | Default | Notes |
+|---|---|---|
+| `SUPABASE_URL` | unset | Hosted path. Absent in development ⇒ auth disabled |
+| `SUPABASE_ANON_KEY` | unset | Public by design; served to the browser via `/api/config` |
+| `SUPABASE_SERVICE_KEY` | unset | Only for administrative provisioning and self-registration. Warns at boot when set |
+| `PIG_OIDC_ISSUER` | unset | On-premises path. **Takes precedence over `SUPABASE_URL`** |
+| `PIG_OIDC_JWKS_URI` | discovered | Set it to skip discovery on an air-gapped network |
+| `PIG_OIDC_AUDIENCE` | unset | Strongly recommended: without it, any token your provider issued for any application in the same tenant is accepted here. Warns, does not refuse |
+| `PIG_OIDC_EMAIL_CLAIMS` | provider defaults | Comma-separated, in preference order |
+
+#### Server
+
+| Variable | Default | Notes |
+|---|---|---|
+| `PIG_PORT` | `8920` | |
+| `PIG_PUBLIC_URL` | `http://localhost:8920` | The single origin the app is served from; CORS and the Google redirect are validated against it |
+| `NODE_ENV` | `development` | `production` activates the identity-provider guard |
+| `PIG_ADMIN_EMAILS` | `''` | Comma-separated. Every address must already have an account — an unregistered address here is a standing offer of admin rights to whoever claims it first |
+| `PIG_INVITE_CODE` | unset | Set it to gate signup |
+| `PIG_SETTINGS_ENCRYPTION_KEY` | unset | Base64-encoded 32 bytes. Required for Notion and Google OAuth; secrets written in the admin UI need it |
+
+#### Prime Intellect
+
+| Variable | Default | Notes |
+|---|---|---|
+| `PRIME_API_KEY` | unset | Scope it to `Availability → Read` only |
+| `PRIME_API_BASE` | `https://api.primeintellect.ai` | The compute/pods host. Inference is a *different* host — see below |
+| `PRIME_SYNC_ENABLED` | `false` | Warns if on without a key |
+| `PRIME_SYNC_INTERVAL_MINUTES` | `30` | |
+
+#### Piggy
+
+The API and the Piggy container read overlapping but distinct sets.
+
+| Variable | Default | Read by | Notes |
+|---|---|---|---|
+| `PIGGY_ENABLED` | `false` | API | Gates the chat surface |
+| **`PIGGY_INFERENCE_API_KEY`** | — | Piggy | Required by the Piggy process. The model credential never reaches the API container |
+| `PIGGY_INFERENCE_BASE` | `https://api.pinference.ai/api/v1` | both | OpenAI-compatible |
+| `PIGGY_MODEL` | `nvidia/nemotron-3-nano-30b-a3b` | both | Admin-selectable at runtime too |

+#### Integrations — all optional, all validated as a group
+
+Setting one member of a group without the others fails at boot rather than
+half-working.
+
+| Group | Variables |
 |---|---|
-| Web | React + Vite + TypeScript, Tailwind, shadcn/ui, light + dark |
+| Slack | `SLACK_BOT_TOKEN`, `SLACK_SIGNING_SECRET` |
-| API | Hono + tRPC on Node 22+ |
+| Buzz | `BUZZ_RELAY_URL`, `BUZZ_PRIVATE_KEY`, `BUZZ_AUTH_TAG` |
-| Database | PostgreSQL 16, Drizzle ORM |
+| Notion import | `NOTION_CLIENT_ID`, `NOTION_CLIENT_SECRET`, `NOTION_REDIRECT_URI` (+ `PIG_SETTINGS_ENCRYPTION_KEY`) |
-| Auth | Supabase (JWT verification only — PIG stores no passwords) |
+| Google Sheets import | `GOOGLE_CLIENT_ID`, `GOOGLE_CLIENT_SECRET`, `GOOGLE_REDIRECT_URI` (+ `PIG_SETTINGS_ENCRYPTION_KEY`) |
-| Agent | Piggy — a worker draining a leased task queue |
-| MCP | `@modelcontextprotocol/sdk` — stdio + Streamable HTTP |
-| Deploy | Docker Compose behind any reverse proxy |
 
-Authorization comes from PIG's own `users` table, never from the mere existence

-of an auth account. An identity provider that PIG shares with another
-application must not grant access here.
 
-## Quick start
+## Architecture
 
-```bash
+A pnpm monorepo. Around 47k lines of TypeScript including tests, 275 tests
-git clone <this-repo> pig && cd pig
+across five packages, green CI.
-npm install
-cp .env.example .env        # then edit it
-npm run db:migrate
-npm run db:seed             # optional — public, sourced, confidence-graded
-npm run dev:api             # :8920
-npm run dev:web             # :5173
-```
-
-Connect an agent:
-
-```bash
-claude mcp add pig -- npx -y @pig/mcp          # stdio
-# or point any MCP client at https://<your-host>/mcp
-```

 ```
 
+Three rules hold the shape:
+
+**Intelligence never lives in the API.** Handlers validate, authorise, call a
+service, serialise. Research, enrichment, scoring and matching heuristics live
+in the service layer or in the agent. The API signals the agent by *writing a
+row to `agent_tasks`*, never by calling it — so the queue survives the agent
+being down and no request thread ever blocks on a model.
+
+**Authentication is not authorisation.** A verified JWT proves someone has an
+account in an identity provider PIG may share with another application. Access
+additionally requires a row in PIG's own `users` table; a token without one
+gets `403 needs_profile`, which the front end turns into a join flow rather
+than a login screen they have already completed. Both providers reduce to
+"verify a bearer token, return a subject and an email" behind
+`apps/api/src/lib/auth-provider.ts`.
+
+**Writes go through one chokepoint.** `apps/api/src/lib/mutation.ts` derives
+zod schemas from the ontology, applies the capability check, runs the write and
+its audit activity in one transaction, and returns a consistent error shape.
+
+## The RBAC model, as it now stands
+
+Eleven capabilities, in `packages/core/src/permissions.ts`, resolved from team
+membership and role and shared by the API and the browser so a disabled button
+and a 403 cannot disagree.
+
+Roles are ranked, and every rule is "at or above": `viewer` < `member` <
+`lead` < `admin`. A platform admin (an address in `PIG_ADMIN_EMAILS`) holds
+everything, platform-wide.
+
+**Writes are team-scoped:**
+
+| Capability | Teams | Minimum role |
+|---|---|---|
+| `deal:write` | supply, demand | member |
+| `commitment:write` | supply | lead |
+| `contract:sign` | supply, demand | admin |
+| `activity:write` | all | member |
+| `data:import` | all | admin |
+| `fact:review` | research | admin |
+| `integration:connect` | all | admin |
+| `settings:admin` | — | platform admin only |
+
+**Reads are platform-wide, deliberately:**
+
+| Capability | Teams | Minimum role | Covers |
+|---|---|---|---|
+| `book:read` | all | viewer | Accounts, contacts, both pipelines, contracts, growth, facts |
+| `economics:read` | supply, demand | member | Supplier cost, break-even price, margin, idle, inventory, the dashboard |
+| `team:read` | all | viewer | The roster |
+
+Read grants are **not** team-scoped, and that is a decision rather than an
+omission: no row-level team filter exists anywhere in the query layer, so a
+"demand only" read grant would be a promise the guard could not keep. The
+honest model is that a read capability is held or it is not, and the *role*
+required to hold it is what separates the roster from the cost book.
+`economics:read` is the one that matters — supplier cost per GPU-hour and
+break-even price *are* the business.
+
+The read half is enforced. The policy table lives in
+`apps/api/src/routes/read-guards.ts` and `createReadGuardRoutes` is mounted in
+`app.ts` **before** the feature routes — Hono runs matched handlers in
+registration order, so a guard registered after its route would return 200 while
+looking correct. `read-governance.test.ts` pins that ordering in both
+directions, and fails when a GET appears that no rule covers, so a new read
+endpoint cannot ship ungoverned by accident.
+
+What it still cannot do is filter *within* a grant: see
+[limitations](#what-is-not-built-yet).
+
+## The agent surface
+
+PIG is a first-class application for agents *and* for humans, and neither is a
+degraded view of the other. There are two distinct surfaces.
+
+### Piggy — the in-app agent
+
+`apps/piggy` is one image running two processes' worth of behaviour:
+
+- **The queue worker** claims a task with `SELECT … FOR UPDATE SKIP LOCKED`
+  inside a transaction, holds a renewable lease (default 300s, renewed at half
+  the interval), and aborts its own work if it ever loses that lease — so two
+  workers can never both be mid-flight on one task. Failures retry with
+  exponential backoff capped at one hour, up to the task's `maxAttempts`. Every
+  attempt writes an `agent_runs` row with the model, the input, the token
+  counts and either a summary or the error. Its tool set is exactly two:
+  `pig_get_subject` and `pig_record_fact`, and a fact is refused without both a
+  source URL and an evidence excerpt.
+- **The chat server** listens on `127.0.0.1:8931` and is never published to the
+  host. The API authenticates the user, forwards bounded context, and calls it
+  with a shared internal bearer token. Chat is **read-only**: seven tools
+  (`pig_get_record`, `pig_get_account_lifecycle` and five page-scoped
+  summaries), each of which aggregates first and returns at most a handful of
+  exemplar rows, because interactive chat runs at 1024 max tokens across at
+  most four turns. Ambient coding tools are rejected before inference by an
+  explicit boundary check.
+
+Piggy is off by default. `PIGGY_ENABLED` defaults to `false` and the Compose
+service sits behind `profiles: ['piggy']`, so a default `docker compose up`
+starts the CRM without it:
+
+```bash
+docker compose -p pig --profile piggy up -d --build
+```
+
+### The MCP server — for the agent you already use
+
+`apps/mcp` speaks **stdio** and holds an API key. It calls the same HTTP API a
+browser does: no database credentials, no privileged path, and deliberately no
+tool that provisions infrastructure, spends money or emails a customer. Nine
+tools, because a sprawling tool list measurably degrades model performance:
+
+| Tool | What it answers |
+|---|---|
+| `pig_whoami` | Who am I acting for, and which teams am I on? |
+| `pig_my_pipeline` | Where are we? What needs attention? |
+| `pig_capacity_match` | What have we bought that would serve this customer? |
+| `pig_margin_report` | What is each block earning against what it cost? |
+| `pig_idle_capacity` | What are we paying for and not selling? |
+| `pig_inventory_search` | What could we buy to cover demand we cannot serve? |
+| `pig_search` | Find an account |
+| `pig_get_account` | Everything about one account |
+| `pig_log_activity` | Record a call, meeting or note |
+
+Mint a key in **Settings → API keys** (shown once), then run it from a clone —
+`@pig/mcp` is a workspace package and is not published to npm:
+
+```bash
+export PIG_URL=https://your-pig-host
+export PIG_API_KEY=pig_...
+claude mcp add pig -- pnpm --dir /path/to/pig exec tsx apps/mcp/src/stdio.ts
+```
+
+There is also a `pig` CLI with `--json` output for scripts and agent kernels;
+see [docs/agents.md](./docs/agents.md).
+
+## Shipping — tag to deploy
+
+CI is Gitea Actions, one sequence, about two minutes. It typechecks every
+package, applies the migration chain **twice** to a real empty Postgres, asserts
+the seed is idempotent, runs 275 unit tests and the critical-path E2E, boots the
+server and curls it, builds the front end, checks the inline theme script still
+hashes to the value the proxy's CSP allows, and builds the Docker image.
+
+Shipping is two steps and the second one is a human:
+
+```bash
+git tag release-2026-08-13 && git push origin release-2026-08-13
+```
+
+1. A push to `main` runs `verify` and stops. **Nothing deploys.**
+2. A `release-*` tag runs the same `verify`, then `publish` pushes
+   `git.karti.ai/pig/pig:<tag>` and `:<short-sha>` to the registry.
+3. Within five minutes `pig-autodeploy.timer` on the production host notices
+   the newest release tag has a different digest, checks the tree out at that
+   tag, and runs `scripts/deploy.sh` with `PIG_IMAGE` set.
+
+The direction of travel is the point: no credential on the shared CI runner can
+execute anything on the production host. The host holds a pull-only token and
+fetches. `deploy.sh` dumps the database first, gates on health, the
+unauthenticated-401 check and a public-origin body marker, and rolls back to
+the previous image if a gate fails — exiting 1 when the previous image was
+restored and 3 when the release under test is still live, because that is the
+one thing an on-call needs at 04:00.
+
+## What is not built yet
+
+Said plainly, because you are going to grep the repo anyway.
+
+**Read authorisation is enforced, but only at the grant.** A capability is held
+or it is not. Once `economics:read` is held, it returns every commitment's cost
+— there is no filter that narrows it to one team's book, because no row-level
+team filter exists anywhere in the query layer. That is the gap to close before
+PIG serves a company where "supply can see supply's costs" is a requirement.
+
+**The HubSpot integration is written, tested and never mounted.**
+`routes/hubspot.ts` and `routes/hubspot-webhook.ts` are both absent from
+`app.ts`, so OAuth, connections, sync jobs, webhook verification and seven
+`hubspot_*` tables are all unreachable from the running server.
+
+**Six of the eight declared agent task kinds are never enqueued.** The worker
+is complete and generic, but only `enrich_account` and `enrich_contact` are
+ever written to `agent_tasks` (both from record creation). `write_brief`,
+`match_capacity`, `detect_idle_capacity`, `summarise_pipeline`,
+`watch_renewal` and `research_supplier` are declared in the ontology and
+nothing produces them. Piggy therefore does far less than the queue implies —
+not because the machinery is missing, but because nothing asks.
+
+**Piggy chat cannot write.** By design for now, but worth stating: the
+interactive agent reads and cites; it cannot create or update a CRM record.
+
+**The MCP server is stdio only.** There is no Streamable HTTP transport and no
+`/mcp` endpoint on the API, so remote MCP clients cannot connect over the
+network — each user runs the server locally against their own API key. The
+package is also not published to npm, so `npx @pig/mcp` does not work.
+
+**No row-level or team-scoped read filtering exists** anywhere in the query
+layer. Every read returns the whole book. This is why read capabilities are
+platform-wide rather than per-team, and it is the thing to build before PIG
+serves a company where that is not acceptable.
+
+**`.env.example` is incomplete.** `POSTGRES_PASSWORD` and
+`PIG_SETTINGS_ENCRYPTION_KEY` are both load-bearing and both missing from it;
+the table above is authoritative. `ANTHROPIC_API_KEY` is declared in the API
+config and read by nothing.
+
+**Not started at all:** email or calendar ingestion, forecasting, quota and
+attainment, invoicing or billing reconciliation, a public API beyond what the
+MCP tools cover, multi-tenancy of any kind, and any mobile application. PIG is
+responsive to 393px; it is not a native app.

+/**
+ * Serving the Learn videos PIG hosts itself.
+ *
+ * ## The trade, stated plainly
+ *
+ * **The files are unauthenticated. The listing is not.** `/api/learn` and
+ * `/api/learn/public` decide who learns that a video exists, what it is called
+ * and which track it belongs to; this route hands the bytes to anyone who can
+ * name the file. That is the same shape every video platform has — a gated
+ * manifest in front of segments on a public CDN — and it is the shape a
+ * `<video>` element actually wants, because a media element re-requests ranges
+ * on every seek and does not carry a bearer token while doing it.
+ *
+ * What it costs: **a URL, once shared, is a permanent public link to that
+ * video**. Someone who has been given the share code can copy the `src` out of
+ * the page and post it, and revoking the Learn access code will not close it.
+ * The only remedies are renaming the file (a new hash) or deleting it. We are
+ * taking that deliberately, because these are product demos meant to be
+ * shareable with the code — the material that must never leak is the concept
+ * tracks, and those are gated by the listing, which is where the boundary
+ * genuinely is.
+ *
+ * The mitigation is the filename. Names are **content-addressed** — a hash in
+ * the middle — so a URL is unguessable and enumerating the directory over HTTP
+ * is not possible: there is no index, and a wrong guess is a flat 404. That
+ * makes the exposure "whoever was given the link" rather than "the internet",
+ * which is exactly what an unlisted video is.
+ *
+ * ## Ranges are not optional
+ *
+ * A `<video>` that cannot be range-requested cannot be scrubbed: the browser
+ * asks for `bytes=…` when the user drags the scrubber, and a server that
+ * answers 200 with the whole file makes seeking either impossible or a
+ * re-download. So `Accept-Ranges: bytes` is advertised and a single range is
+ * honoured with a 206. This is also why the route streams from a file
+ * descriptor rather than reading the file into memory: these are hundreds of
+ * megabytes and several viewers may be seeking at once.
+ *
+ * ## Why the path cannot escape the directory
+ *
+ * The filename is validated by the same allowlist that decides whether a row
+ * may exist at all (`isLearnMediaFilename` in `@pig/core`), so the pattern
+ * that admits a video source and the pattern that admits a file read are one
+ * pattern rather than two that drift. It permits no slash and no `..`. The
+ * resolved path is then checked to be inside the root anyway, because a
+ * defence that rests on a single regular expression rests on nobody ever
+ * editing that regular expression.

+/**
+ * Learn — the member curriculum, the admin CRUD, and the one door in this API
+ * that opens without a principal.
+ *
+ * ## The security shape, which is the reason this file is long
+ *
+ * Everywhere else in PIG a request resolves a `Principal` and then a
+ * capability check decides what it may do. A code-holder has no account, so
+ * there is no principal to resolve — and the tempting shortcut, minting a
+ * synthetic one, is the thing this design exists to refuse. A principal is
+ * accepted by every downstream handler by construction; the only thing keeping
+ * it out of the CRM would be that each of those handlers remembered to check a
+ * capability. One that forgot would leak the book of business to anyone
+ * holding a marketing share code, and nothing would report an error.
+ *
+ * So the code mints a **scoped bearer token that is not a credential for this
+ * API at all**. It is an HMAC over a scope string and an expiry, verified by
+ * exactly one handler, and `authenticate()` never sees it. Presenting it to
+ * `/api/dashboard` produces the same 401 as presenting nothing, because to the
+ * authenticator it is simply a bearer token that is not a JWT and does not
+ * start with `pig_`. There is a test that asserts precisely this.
+ *
+ * The token's signing key is derived from the stored access code, so rotating
+ * the code invalidates every outstanding token as a side effect rather than
+ * requiring a second revocation mechanism.
+ *
+ * ## The public read
+ *
+ * `GET /api/learn/public` is written so that it is *structurally* incapable of
+ * naming another row: the predicates are two literals, there is no parameter
+ * that reaches the WHERE clause, and the selected columns are enumerated. It
+ * cannot be widened by a query string because it does not read one.
+ *
+ * ## What may be code-visible
+ *
+ * Only the platform track. Enforced here in the write path AND by a CHECK
+ * constraint on the table. Not in the UI: a form is not a security boundary,
+ * and a concept video becoming anon-visible through a mis-set select is the
+ * failure that matters.

+/**
+ * The quarterly calendar — a projection, not a table.
+ *
+ * Everything with a date on it already lives somewhere: contracts expire,
+ * obligations fall due, commitments open and close, holds lapse, export
+ * authorisations run out. This service reads those columns where they are and
+ * emits one common shape. Nothing here is stored, and nothing here can drift
+ * from the record it describes.
+ *
+ * Three things shape the implementation.
+ *
+ * **One query per source, each with its own date predicate and its own
+ * limit.** The convention elsewhere in this API is a flat `.limit(300)`
+ * ordered by `updated_at`, with the caller filtering by date in the browser —
+ * which means the deals actually closing this quarter are not guaranteed to be
+ * in the response at all. That is precisely the bug this endpoint exists to
+ * fix, so every predicate is server-side and every source is bounded
+ * independently rather than competing for one budget.
+ *
+ * **Totals are separate aggregate queries.** If the header counted the rows in
+ * the list it would under-report the moment any source truncated, and a
+ * quarterly figure that silently shrinks is worse than no figure. The counts
+ * are exact even when the list is cut short.
+ *
+ * **Renewal comes from `renewalAlarm()`.** The rule — expiry minus notice
+ * days, only when auto-renewal is on — is defined once, in the contracts
+ * service. The SQL below narrows candidates with the same arithmetic so the
+ * scan stays bounded, but every date and every state on an emitted event comes
+ * from calling that function. If the rule changes, it changes there.

+ * five `execute` bodies underneath: every where clause, every `Number(gpuHours)`
+ * coercion and every date comparison was covered by tsc alone. The defect that
+ * prompted this suite — a headline quoting `list.length` from a capped query as
+ * if it were a total — typechecks perfectly.
+ *
+ * It lives in `e2e/` rather than `test/` for one reason: the unit suite runs in
+ * CI BEFORE the migration step, against a database with no tables. `test:e2e`
+ * runs after migrate and seed, which is the only point at which a query here
+ * can mean anything.
+ *
+ * Every assertion is a DELTA against a reading taken before the fixture is
+ * inserted. The tools are book-wide by design — there is no tenant to scope
+ * them to — so they see the seed, the demo book and whatever the API's own E2E
+ * left behind. Absolute figures would be a test of the seed, not of the tool.

+ * palette on focus, and that is a keyboard trap: Tab moved into the field,
+ * the modal took over, Escape left focus on `<body>`, and Tab from there ran
+ * the same three elements and reopened the dialog — so no keyboard user could
+ * ever reach the nav, the Piggy toggle or the page. A field that cannot be
+ * focused without being replaced is not a field.
+ *
+ * The alternative — a real input filtering inline and escalating on Enter —
+ * was rejected because the palette is the thing that answers, and an inline
+ * filter would be a second search that ranks differently from the one ⌘K
+ * opens. One search, one ranking; the control that opens it says so honestly.
+ * (This is also what shadcn's own examples do.)

+/**
+ * The sidebar primitive.
+ *
+ * shadcn's `sidebar` block, with its API kept intact and two deliberate
+ * changes to its internals:
+ *
+ *   1. The desktop pane is `sticky`, not `fixed`. Upstream renders an
+ *      invisible width-holding div next to a `fixed inset-y-0` pane so the
+ *      pane can slide fully off-canvas. PIG only ever wants the icon rail, and
+ *      a sticky pane in a flex row gets the same collapse animation from one
+ *      element instead of two — and, unlike `inset-y-0`, it can start below a
+ *      full-width application header. That header is the whole point of the
+ *      layout, so the fixed variant was not usable as shipped.
+ *   2. Every control clears 44px, and the icon rail is 64px rather than
+ *      shadcn's 48px so that a 44px button still has gutters. A 32px icon
+ *      button is the one thing in the upstream block that fails PIG's own
+ *      touch-target rule, and the rail is reachable on a tablet.
+ *
+ * Colours come from `--sidebar-*` in index.css, which alias the existing
+ * surface and accent variables rather than introducing a second palette — so
+ * the sidebar re-tints with the user's chosen accent and needs no dark-mode
+ * pass of its own.
+ *
+ * `collapsible="offcanvas"`, the `floating` and `inset` variants and the
+ * submenu parts are not implemented, because nothing here uses them and an
+ * unexercised variant is a variant that is quietly broken.
