Rebuild the shell, add Calendar and Learn, and govern reads

Seven parallel agents and an adversarial verification pass. The three things
worth knowing before reading the diff:

RBAC WAS ALREADY BUILT. docs/build-plan.md marks F2 and F3 outstanding and is
stale — packages/core/src/permissions.ts and lib/mutation.ts shipped long ago.
So this does not rebuild them; it closes the gaps an audit found. The big one
is that reads were entirely ungoverned: every GET was "any authenticated
member", so a junior demand rep and a research contractor could both pull
per-block supplier cost and break-even prices from /api/capacity/margin, and
every contract's negotiated terms. For a company whose margin is the business,
that was the hole that mattered. Adds book:read / economics:read / team:read,
a readGuard middleware, and a `viewer` role below member.

THE BUTTON AND THE 403 DISAGREED — the exact thing F3 said must never happen.
Contracts.tsx never called can() at all, so its save button was always enabled
against a server requiring contract:sign; Capacity.tsx gated commitment
creation on deal:write/demand while the server wanted commitment:write/supply.

POST /api/activities was the one write bypassing executeMutation: no capability
check, and any member could mutate accounts.lastActivityAt as a side effect.
It is now a proper mutation() behind activity:write.

The shell becomes three panes — a collapsible shadcn sidebar with an account
switcher on the Piggy accent, a header with real search, and Piggy docked to
the right, page-aware and persistent across navigation. The phone keeps its
bottom tab bar, which is the thing this product already beat trycompai/crm on,
and gains the sidebar as a sheet.

Calendar is a projection over thirteen dated sources rather than a new table,
because a table would duplicate dates that already live on contracts, deals and
commitments and would drift — and one ledger answering the question is the
whole argument. It surfaces export_authorizations and compliance_artifacts,
which had indexed expires_at columns, schema comments saying they must be
alerted on, and no read endpoint or UI anywhere.

Learn carries two tracks. Concepts are members-only; the platform track can be
opened with a share code by someone with no account. The code mints a scoped
learn-only token and never a Principal — every route here resolves a principal
and then checks capabilities, so a principal-minting code would be one missing
check away from leaking the book. "Only platform-track rows may be code-visible"
is a database CHECK constraint as well as a write-path rule, and a test asserts
a valid learn token still gets 401 on /api/dashboard, /api/accounts and
/api/contracts — the same invariant scripts/deploy.sh refuses to ship without.

CD becomes tag-to-ship. CI publishes an image to the Gitea registry on a
release-* tag and cloud-2 pulls it, so no credential on the shared runner can
execute anything on production — by construction rather than by policy. Both
halves of deploy.sh's original rule survive: nothing on the runner reaches the
host, and a human still decides when it ships. deploy.sh gains a rollback and a
public-origin check, and PIG_IMAGE now reaches compose through `sudo env`,
without which sudo's env_reset silently resolved every release to pig:local.

Tests 141 -> 261.

-### The architectural rule
+## The two-sided data model
 
-> **Intelligence never lives in the API.**
+Forty-seven tables, but the shape is small. These are the ones that carry the
+thesis:
 
-The API does HTTP, auth, validation, and sync. All research, enrichment,
-scoring, and identity matching lives in the agent. They communicate through a
-table, never a direct call. This separation is borrowed from
-[Comp AI CRM](https://github.com/trycompai/crm) and it is the single most
-load-bearing decision in the codebase.
+| 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 |
 
-## What makes it compute-native
+Two pipelines, with stages taken from how the market operates:
 
-- **`inventory_listings`** mirrors the Prime Intellect availability API
-  field-for-field — `gpuType`, `socket`, `interconnectType`, `stockStatus`,
-  `security` (secure vs community cloud), `prices.onDemand`, `provisioningTime`.
-  Sync is a straight mapping, not an ETL project.
-- **`capacity_commitments`** records what you bought: term, GPU-hours,
-  cost per GPU-hour, floor and ceiling.
-- **`contracts`** is polymorphic over party and type — MSA, DPA, SLA, order
-  form, capacity commitment — because the supply side negotiates heavyweight
-  paper while the self-serve demand side runs on a reliability tier and a
-  credits policy instead of a signed uptime guarantee.
-- **Two real pipelines**, with stages taken from how this market actually
-  operates rather than invented:
+```
+Demand:  qualification → legal → scoping → proposal → procurement
+         → POC → deployment → expansion            (+ closed_won / closed_lost)

-| Layer | Choice |

+## Self-hosting
 
-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.
+### Requirements
 
-## Quick start
+Node 22+, pnpm 11+ (pinned by `packageManager`; `corepack enable` installs it),
+and a PostgreSQL 16 database that PIG owns exclusively.
+
+### Development
 
 ```bash
-git clone <this-repo> pig && cd pig
+corepack enable
 pnpm install
-cp .env.example .env        # then edit it
+
+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 — public, sourced, confidence-graded
-pnpm run dev:api             # :8920
-pnpm run dev:web             # :5173
+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
 ```
 
-Connect an agent:
+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
-claude mcp add pig -- npx -y @pig/mcp          # stdio
-# or point any MCP client at https://<your-host>/mcp
+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
 ```
 
-## Repository layout
+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 |
+| `PIGGY_LEASE_SECONDS` | `300` | both | Queue lease duration |
+| `PIGGY_POLL_INTERVAL_MS` | `2000` | Piggy | |
+| `PIGGY_MAX_TOKENS` | `1024` | Piggy | |
+| `PIGGY_WORKER_ID` | `hostname:pid` | Piggy | |
+| `PIGGY_INTERNAL_URL` | unset | API | `http://piggy:8931` under Compose |
+| **`PIGGY_INTERNAL_TOKEN`** | — | both | Min 32 chars; required by the Piggy process. Never put it in a query string |
+| `PIGGY_CHAT_HOST` | `127.0.0.1` | Piggy | |
+| `PIGGY_CHAT_PORT` | `8931` | Piggy | Never published to the host |
+| `PIGGY_CHAT_ALLOW_NON_LOOPBACK` | `false` | Piggy | Compose sets `true`, because the API reaches it across the Compose network |
+
+#### 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 |
+|---|---|
+| Slack | `SLACK_BOT_TOKEN`, `SLACK_SIGNING_SECRET` |
+| Buzz | `BUZZ_RELAY_URL`, `BUZZ_PRIVATE_KEY`, `BUZZ_AUTH_TAG` |
+| Notion import | `NOTION_CLIENT_ID`, `NOTION_CLIENT_SECRET`, `NOTION_REDIRECT_URI` (+ `PIG_SETTINGS_ENCRYPTION_KEY`) |
+| Google Sheets import | `GOOGLE_CLIENT_ID`, `GOOGLE_CLIENT_SECRET`, `GOOGLE_REDIRECT_URI` (+ `PIG_SETTINGS_ENCRYPTION_KEY`) |
+
+`GOOGLE_REDIRECT_URI` must be exactly `<PIG_PUBLIC_URL origin>/oauth/google/callback`.

 ```
 
+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 written and tested but not yet enforced.** The policy
+table (`apps/api/src/routes/read-guards.ts`) and its middleware exist, and
+`read-governance.test.ts` fails when a GET appears that no rule covers — but
+`createReadGuardRoutes` is not mounted in `app.ts`, so today every
+authenticated member can read the whole book including cost. 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 261 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 not enforced.** As above: the policy, the middleware
+and the governance test all exist; the router line that mounts them does not.
+Any authenticated member can currently read cost and margin regardless of team
+or role. This is the most significant gap in the product and it is one line in
+`app.ts`.
+
+**Four route modules are written, tested and never mounted.**
+`routes/read-guards.ts`, `routes/learn.ts`, `routes/hubspot.ts` and
+`routes/hubspot-webhook.ts` are all absent from `app.ts`. Consequences: the
+**Learn** page is in the navigation and its API answers 404, and the HubSpot
+integration — OAuth, connections, sync jobs, webhook verification, seven
+`hubspot_*` tables — is unreachable. `routes/activities.ts` is likewise
+unmounted, but harmlessly: an older inline `POST /api/activities` in `app.ts`
+still serves it.
+
+**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.

 ## A note on seed data
 
 PIG ships with a roster of publicly documented people so the application is
-legible on first run. Every record carries a confidence grade and a source URL.
-**No email addresses are included or inferred.** Records that could not be
-independently sourced are marked as such rather than quietly presented as fact,
-and people who are demonstrably *not* staff — alumni, residency participants —
-are labelled accordingly. See [docs/seed-data.md](./docs/seed-data.md).

+ * 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.

+ * has no way to mint one and calling the API back through the network to read
+ * a database it already holds a handle to would be a round trip for nothing —
+ * so the queries are ported here as direct Drizzle reads.
+ *
+ * The calendar is the exception, and deliberately so. Its projection spans

+ * on /calendar; a second implementation here would not merely duplicate it,
+ * it would disagree with it, and Piggy contradicting the page it has just been
+ * told it is reading is worse than Piggy having no calendar tool. So @pig/piggy
+ * depends on @pig/api and calls `CalendarService` in-process — the service
+ * layer takes a `Database`, not a request, precisely so it can be called this
+ * way. Lifting it into @pig/core instead would drag nine table imports into a
+ * package the browser bundles.
+ *
+ * The hard constraint is size, not capability. Interactive chat runs at
+ * `max_tokens` 1024 across at most four turns, so a tool that returns rows
+ * spends the whole budget on transcription and truncates mid-answer. Every

+ * The application header: logo, where you are, search, Piggy.
+ *
+ * Search reads as a field because that is what people look for, but it is a

+ * 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.

+ * Learn — two tracks, one of which a stranger with the share code can see.
+ *
+ * The page has to render correctly for two very different callers, and the
+ * difference is decided by the server, never by anything held here:
+ *
+ *   a member  — `GET /api/learn` succeeds and returns all three tracks.
+ *   a code-holder — that call answers 401, so the page falls back to the code
+ *                   gate, and afterwards reads `GET /api/learn/public`, which
+ *                   returns platform walkthroughs and nothing else.
+ *
+ * Deriving the mode from the 401 rather than from an identity hook is what
+ * lets this file work both inside the authenticated shell (where it lives
+ * today) and outside it, which is what the anonymous `/learn` route needs. It
+ * also means the browser is never the thing deciding what a code-holder may
+ * see — it asks, and the API answers with a smaller set.
+ *
+ * **The locked Concepts panel is deliberate, not an oversight.** A code-holder
+ * is shown that supply and demand material exists and is behind sign-in. That
+ * was an explicit product decision: the point of the page for an outsider is
+ * partly to advertise the rest of it.
+ *
+ * Nothing here builds an embed URL. Every `iframe src` arrives from the API
+ * already resolved through the host allowlist in `@pig/core`; a resource the
+ * server could not resolve is not in the response at all. Concatenating a URL
+ * in this file would reintroduce exactly the hole the allowlist closes.

+satisfies every check that only asks whether something responded.
+`scripts/deploy.sh` now asserts the body is non-empty and contains the
+application's mount point for this reason.
+
 ## Upgrading
 
+### By hand
+
 ```bash
-git pull
-docker compose -p pig up -d --build
-docker compose -p pig exec app pnpm exec tsx packages/db/src/migrate.ts
+bash scripts/deploy.sh
 ```
 
+It fetches `origin/main`, dumps the database, builds, migrates from a one-off
+container, starts the app, and refuses to call the deploy done until the health
+endpoint, the unauthenticated-401 gate and the public origin all agree.
+
+### By tag — the normal path
+
+Shipping is two steps and the second one is a human being:
+
+```bash
+git tag release-2026-08-13 && git push origin release-2026-08-13
+```
+
+That is the entire ship decision. What follows:
+
+1. CI runs the full `verify` job against the tagged commit — the same job a
+   push to main runs. A tag does not skip verification.
+2. Only if that passes, the `publish` job builds and pushes
+   `git.karti.ai/pig/pig:<tag>` and `:<short-sha>` to the Gitea registry.
+3. Within five minutes `pig-autodeploy.timer` on the host notices that the
+   newest `release-*` tag has a digest different from the running container,
+   checks the tree out at that tag, and runs `scripts/deploy.sh` with
+   `PIG_IMAGE` set — so it pulls the published image instead of rebuilding it.
+
+**Push to main deploys nothing.** Tagging does.
+
+The direction of travel is the point. No credential on the shared CI runner can
+execute anything on this host; the host holds a pull-only registry token and
+fetches. That preserves both halves of the constraint written at the top of
+`scripts/deploy.sh` — no production key on the runner, and a human still
+choosing when it ships.
+
+**Trap: `sudo` throws `PIG_IMAGE` away.** The default sudoers policy sets
+`env_reset`, so `PIG_IMAGE=… sudo docker compose …` hands compose an environment
+without it and compose interpolates the `pig:local` fallback from
+`docker-compose.yml`. The pull then dies with "pull access denied for pig" — and
+if it had not died, the migrate, the `up` and the rollback would all have run
+the stale local image while the log named the release tag. Every compose
+invocation in `deploy.sh` therefore goes through the `dc()` wrapper, which uses
+`sudo env PIG_IMAGE=… docker compose …`; `sudo -E` and bare `sudo VAR=val` are
+both refused by that same policy. Anything new that shells out to compose must
+use the wrapper.
+
+### Rollback
+
+`scripts/deploy.sh` records the image the app container was running before it
+replaces it. If the health check, the unauthenticated-401 gate, or the
+public-origin marker check fails, it re-tags that image, restarts the app on it,
+reports whether the restored version is healthy, and exits non-zero. Previously
+those exits left the broken release live, which was fine when a human was
+watching the terminal and an outage when the poller ran at 04:00.
+
+**The exit code says what is serving**, because that is the one thing the
+on-call needs at 04:00 and `autodeploy.sh` can see nothing else:
+
+| Exit | Meaning |
+|---|---|
+| 0 | deployed |
+| 1 | a gate failed and the **previous** image was restored |
+| 3 | a gate failed and the **release under test is still live** |
+
+3 covers the cases where a rollback was not attempted (the fault is not
+attributable to the release), where there was no previous image to restore, and
+where the restore itself did not come up. `autodeploy.sh` logs a different
+sentence for each, so the journal never claims a rollback that did not happen.
+
+Two things it deliberately does **not** do:
+
+- **It does not roll the database back.** Migrations are additive, so the
+  previous image runs against the new schema. The dump taken before the
+  migration is the escape hatch for when that is not true.
+- **It does not roll back when the public origin answers with an EMPTY body.**
+  Something terminated TLS and replied, so the fault is the proxy — see `bind`
+  below — and the previous image would fail the same check. Exit 3.
+
+It *does* roll back when the origin answers with a **non-empty** body that lacks
+the marker. A proxy fault cannot serve a wrong-but-populated page for this
+hostname; a bad release can — a changed Vite `base`, a Dockerfile step that
+stopped copying `apps/web/dist`. Every earlier gate passes in that state, so
+this is the only one that fires, and refusing to roll back would leave the
+broken release facing the public.
+
+If curl cannot reach the public origin **at all** (no hairpin for the public
+name, egress to 443 filtered), that is not a failed deploy: it is a host that
+cannot see itself from outside, and blacklisting the digest over it costs a
+release. The script warns and exits 0. On a host where the public name really is
+reachable from the host, set `PIG_DEPLOY_REQUIRE_PUBLIC=1` to make it fatal
+(exit 3).
+
+`scripts/autodeploy.sh` writes the failed digest to
+`/var/lib/pig/failed-release` and will not retry it, so one bad tag does not
+become a five-minute restart loop. Delete that file, or publish a new tag, to
+try again.
+
+To pin a specific release by hand:
+
+```bash
+git checkout --detach refs/tags/release-2026-08-12
+PIG_IMAGE=git.karti.ai/pig/pig:release-2026-08-12 bash scripts/deploy.sh
+```
+
+Check the tree out at the tag as well as setting `PIG_IMAGE`. The compose file
+and the migrations must come from the same commit as the image; with
+`PIG_IMAGE` set, `deploy.sh` deliberately does not touch git, precisely so it
+cannot drag you back to `main` behind your back.
+
 Migrations are additive and safe to re-run; Drizzle tracks what has been
-applied. Take a dump before a major upgrade anyway:
+applied. `deploy.sh` takes a dump before every deploy; take one by hand before
+a major upgrade anyway:

+
+## Left to do
+
+In rough order of value. The first four are all "wire up something that already
+exists", which is a strange shape for a backlog and worth taking seriously
+because that is exactly the kind of work that stays undone.
+
+**1. Mount `createReadGuardRoutes`.** The read half of the permission model —
+`book:read`, `economics:read`, `team:read` — has a policy table, middleware, and
+a governance test that fails when a GET appears with no rule covering it. None
+of it runs, because `app.ts` never mounts it. Until it does, any authenticated
+member reads supplier cost, break-even price and every margin total regardless
+of team or role. Registration order is load-bearing: Hono runs matched handlers
+in the order they were registered, so the guard must be mounted before the
+handlers it guards.
+
+**2. Mount `learn.ts`.** `/learn` is in the navigation and every one of its API
+paths answers 404.
+
+**3. Enqueue the other six agent task kinds.** `AGENT_TASK_KINDS` declares
+eight. Only `enrich_account` and `enrich_contact` are ever written to
+`agent_tasks`, both from record creation in `routes/records.ts`. `write_brief`,
+`match_capacity`, `detect_idle_capacity`, `summarise_pipeline`, `watch_renewal`
+and `research_supplier` have no producer anywhere. The worker is generic and
+complete; the gap is entirely on the enqueue side, and each one is a few lines
+in the service that already computes the underlying answer.
+
+**4. Mount the HubSpot routes, or delete them.** Seven `hubspot_*` tables, an
+OAuth flow, sync cursors, jobs and a verified webhook endpoint, all written,
+all tested, all unreachable. Whichever way this goes it should not stay in this
+state — dead-but-tested code reads as shipped to anyone grepping the repo.
+
+**5. Row-level or team-scoped reads.** Every read returns the whole book. This
+is why read capabilities are platform-wide, and it is the honest reason the
+permission model says so out loud. It is also the thing to build before PIG
+serves a company where that is not acceptable.
+
+**6. Piggy writes.** Interactive chat is read-only by design for now. The
+queue-side agent writes only to `facts`. A write path for the chat agent needs
+the same evidence discipline plus a confirmation step, and should not be added
+casually.
+
+**7. Fill in `.env.example`.** `POSTGRES_PASSWORD` and
+`PIG_SETTINGS_ENCRYPTION_KEY` are both load-bearing and both missing from it.
+`ANTHROPIC_API_KEY` is declared in `apps/api/src/lib/config.ts` and read by
+nothing — remove it or use it.
+
+**8. A remote MCP transport.** The server is stdio only; there is no
+Streamable HTTP transport and no `/mcp` endpoint on the API, so every user runs
+the server locally. The package is also unpublished, so `npx @pig/mcp` does not
+work and the documented install command has to be a path into a clone.
+
+Not started at all, and deliberately: email or calendar ingestion, forecasting,
+quota and attainment, invoicing or billing reconciliation, multi-tenancy, and
+any native mobile application.

 ## On borrowing from Comp AI CRM
 
-Their repo (MIT) was cloned and inventoried. Findings that shaped this plan:
+Their repo (MIT) was cloned and inventoried early on, and three findings shaped
+the plan. All three have since been acted on.
 
-**Their component library is far deeper — 68 primitives to our 9.** Notably
-`data-table`, `command`, `sheet`, `drawer`, `combobox`, `chart`,
-`sortable-list`, and a set of agent-chat components (`message`, `reasoning`,
-`thinking-indicator`, `thread-message`, `suggestion`) that map almost exactly
-onto what Piggy will need.
+**Their component library was far deeper — 68 primitives to our 9 at the time.**
+PIG now has 22, including the ones that mattered: `data-table`, `command`,
+`sheet`, `drawer`, `sidebar`, `form`. The agent-chat compositions
+(`message`, `reasoning`, `thinking-indicator`) were rebuilt rather than copied,
+inside `PiggyChat.tsx`.
 
-**`SourcedValue` / `Provenance` is worth adopting outright.** A dotted underline
-on any agent-derived value, with a tooltip carrying the claim, the reasons, when
-it was observed, and the source URL. PIG already has that data — `facts` holds
-score, band, evidence and `sourceUrl` — and nothing currently surfaces it.

+underline on any agent-derived value, with a tooltip carrying the claim, the
+reasons, when it was observed and the source URL. PIG already held that data in
+`facts` and surfaced none of it. It does now.
 
-**But we are ahead of them on mobile, not behind.** Measured across both repos:
-
-| | Comp AI | PIG |
-|---|---|---|
-| tsx files | 329 | 16 |
-| Responsive utilities | 211 (0.6/file) | 58 (3.6/file) |
-| Safe-area handling | 0 | 5 |
-| Mobile nav | none found | bottom tab bar |
-
-They have no drawer or sheet used for navigation, no `viewport-fit`, and no
-safe-area insets anywhere. Their app is effectively desktop-only. So the plan
-below adds *depth* from them, not mobile behaviour.
+**We were ahead of them on mobile, not behind**, and the ratio has held: PIG is
+63 `.tsx` files with safe-area handling, a bottom tab bar, a sidebar Sheet and a
+hard rule that no route may scroll sideways at 393px. Their app is effectively
+desktop-only.
 
 **Do not copy their component files.** Most are shadcn/ui originals, which are
 MIT and designed to be installed from upstream — take them from source, where
-they are canonical and current. Borrow their *compositions* (data-table,
-provenance, agent chat) as ideas, and credit in NOTICE as already done.

-## Waves
-
-### Wave 0 — Foundation (must finish before Wave 1)
-
-Three tracks. F1 and F3 are independent of each other; F2 should follow F3, or
-the two should be built together, because the write path needs the permission
-model to call into.
-
-| | Task | Why it blocks |
-|---|---|---|
-| **F1** | Install the shadcn primitive set: dialog, sheet, drawer, select, dropdown-menu, table, tabs, tooltip, popover, command, form, switch, textarea, label, separator, sonner, avatar, checkbox, radio-group | Every form and table below needs these. Building them ad hoc in parallel guarantees five inconsistent buttons. |
-| **F3** | **RBAC.** A real permission model: capability checks (`deal:write`, `commitment:write`, `contract:sign`, `data:import`, `settings:admin`) resolved from team membership and role, enforced in one place, and used to disable the UI control as well as reject the request — so the button and the 403 cannot disagree. | Today authorization stops at "is a member". Eight CRUD tracks and a bulk-import feature are about to land; without this each invents its own check, and import in particular is a bulk write that must not be available to everyone. |
-| **F2** | A shared write-path convention in the API: zod schemas derived from the ontology, a mutation helper, consistent error shapes, automatic activity logging, and capability checks from F3 | Eight CRUD tasks land at once in Wave 1. Without a settled pattern they will each invent one. |
-
-### Wave 1 — Parallel build (up to ~10 tracks)
-
-Backend tracks need only **F2**. Frontend tracks need **F1**.
-
-**Backend**
-
-| | Task | Depends on |
-|---|---|---|
-| **A1** | Allocations + capacity commitments write API, with the availability invariant enforced server-side (cannot allocate beyond the shape) | F2 |
-| **A2** | API keys: generate, list, revoke. Show the plaintext once. | F2 |
-| **A3** | Auth-provider seam — extract Supabase behind an interface so OIDC is a second implementation | — |
-| **A4** | **Piggy**: worker draining `agent_tasks`, `AgentProvider` interface, prime-agent adapter using `defineTool` with PIG tools only (no bash, no filesystem), writing to `facts` | — |
-| **A5** | Slack adapter: link channels to accounts, post stage changes and idle alerts, slash command for capacity match | F2 |
-| **A6** | Buzz adapter behind the same notifier interface as Slack | A5 |
-| **A7** | `pig` CLI with `--json` output, for prime-agent's kernel and for scripts | A2 |
-
-| **A12** | **Capacity tiers.** Add a `government` (sovereign) tier alongside `secure_cloud` and `community_cloud`. A schema change with a migration, plus matching rules: a government requirement must never be satisfied by community capacity, and the tier interacts with the export-control predicate already in `compliance.ts`. | — |
-| **A14** | **Import framework.** CSV and Excel first, since both are just tabular: upload, column mapping, a dry-run preview showing what would be created or updated, per-row validation and error reporting, and an idempotent commit keyed on a chosen column. Gated on `data:import`. | F2, F3 |
-| **A15** | **Notion import.** Notion databases are tables with typed properties, so this maps onto A14's mapping step rather than being a separate importer. OAuth, database picker, property→field mapping. | A14 |
-| **A16** | **Google Sheets import.** Same shape as A15: OAuth, sheet and range picker, then A14's mapping. | A14 |
-
-**Frontend**
-
-| | Task | Depends on |
-|---|---|---|
-| **A8** | Data table (sort, filter, paginate, column visibility) + ⌘K command palette | F1 |
-| **A9** | `SourcedValue` / provenance display, wired to `facts`; fact review queue (approve/dismiss proposals) | F1 |
-| **A10** | **Contracts UI.** The schema is the richest part of PIG and nothing surfaces it. Build it out fully and plausibly: MSA / DPA / SLA / order form / capacity commitment, the parent-child hierarchy with order-form-beats-MSA precedence, negotiated SLA terms (uptime target, measurement unit and window, remedy type including fee abatement with its trigger duration, credit tiers and cap, claim deadline, credit expiry, spare-pool scope, maintenance classes, reasonable-endeavours carve-out, RCA hours), obligations with renewal alarms, and take-or-pay / prepay / termination-tier fields that make a backlog figure meaningful. Treat the field set as a first draft to be corrected by anyone who negotiates these for a living. | F1, F2 |
-| **A11** | Record create/edit sheets for accounts, contacts, demand deals, supply deals | F1, F2 |
-| **A13** | **Admin settings.** Platform-admin-only page: Piggy's model (defaulting to a Nemotron model on Prime Intellect inference), the inference endpoint, invite management, team and role administration, Prime Intellect API key, and sync toggles. | F1, F3 |
-
-### Wave 2 — Integration (needs Wave 1)
-
-| | Task | Depends on |
-|---|---|---|
-| **B1** | Allocation UI: allocate capacity to a deal from the matcher, place and release holds | A1, A8, A11 |
-| **B2** | Piggy chat UI: streaming, reasoning, tool calls, in-record ask | A4, F1 |
-| **B3** | Settings for Slack/Buzz connections and channel links | A5, A6, F1 |
-| **B4** | End-to-end tests over the critical paths: register → create a commitment → allocate → see margin move | B1 |
-

-## Sequencing advice
-
-Build **F1 and F2 first and alone.** They are small and they are the interface
-every other track codes against. Starting Wave 1 before they settle is how
-parallel work turns into merge conflict.
-
-**A1 and A2 are the highest value in Wave 1** — they close the two gaps that
-block a demo. If only two things get done, do those.
-
-**A4 (Piggy) is fully independent** and can start immediately alongside
-Wave 0; it touches no UI and no shared API conventions.
-
-**A3 (auth seam) should land before any second deployment exists.** It is cheap
-now and expensive once an on-prem install has to keep working.
-
-**F3 (RBAC) gates the import work.** Bulk import is the single most dangerous
-write in the product — one bad mapping can rewrite thousands of records — so it
-must not ship before there is a real answer to who may run it.
-
-**A12 (capacity tiers) is a schema change**, so it is cheaper before the tables
-carry real data than after.

+ * walkthroughs, demos. The distinction is load-bearing rather than cosmetic,

+ *
+ * **Only the platform track may be visible to a code-holder.** Someone holding

+ * works, because that is a sales asset. They may not see how we source and
+ * price capacity. This predicate is enforced three times on purpose — here, in
+ * the API write path, and in a database CHECK constraint — because a concept
+ * video becoming anon-visible through a mistake in a form is the failure that
+ * matters, and a UI-only rule does not survive an API caller.
+ *
+ * **The allowlist is the whole XSS surface of the feature.** A learn resource
+ * is a URL somebody pasted, and it ends up as an `iframe src`. So a pasted URL
+ * is never stored as a source and never rendered as one: it is resolved
+ * through the table below into a *provider* and an *external id*, and every
+ * embed URL is rebuilt from a hardcoded template and a pattern-checked id.
+ * Anything the table does not match is rejected at the write path, so a row
+ * that cannot be rendered safely cannot exist.
+ *
+ * Adding a provider is one row here plus one host in the proxy's `frame-src`
+ * (see `LEARN_FRAME_SRC_HOSTS`). Do not add a row whose URL shape has not been
+ * checked against the running service — the id extraction is what decides
