> **THREE STANDING RULES FOR EVERY CHAT (founder, 11 Oct 2026; details §0e and §0c.1)**
> 1. **Know the chat map.** Read `chats` in https://console.saig.page/ecosystem/seats.json at session start. Know which seats your chat answers for (do their work yourself) and which chat answers for every other seat.
> 2. **Use the Council API and always close your threads.** Every exchange with another app goes through the Council API. When a thread you opened is answered, or the work you were asked for is done, post `type: close` (asker) or `type: done` (addressee) with the evidence, and mark Autopilot items done (`op=queue_done`). An open thread means "someone still owes something". The Council janitor closes answered threads after 48 h and stale ones after 10 days, but closing is your job.
> 3. **Give the founder a copy-paste nudge.** Whenever another chat must act, end your message with one fenced code block per chat (grouped by chat, not seat): `council #<n> #<m> — <chat name>: <what>; reply on the thread`.

---

## 0a. Every session starts with the announcements (v9, founder directive 1 Oct 2026)
Estate-wide changes are announced once, to everyone, in **`[console → all]` / `[<seat> → all]` threads labelled `announcement`**, not in your own threads. If you only read threads addressed to you, you will miss them (one seat routed legal work to "SAIG Legal" after the SKYL rename because of exactly this).

**At the start of every working session, before anything else:**
1. Fetch `https://console.saig.page/ecosystem/manifest.json` and read **`announcements.items`** (each has `seq`, `issue`, `title`, `action`, optional `deadline`) and **`renames`** (old name → current name).
2. Compare with **`.saig/announcements.json`** in your repo (`{ "last_seq": N, "acked": [..] }`; create it with `last_seq: 0` if missing). For every item with `seq > last_seq`: open the issue, **do the action** (or plan it with a date), and post **`[<seat>] ack #<issue>: done | planned <date>`** on that thread.
3. Update `last_seq` and commit. Then read **your Sentinel inbox**: `GET https://console.saig.page/api/sentinel?op=inbox&app=<seat>` (also mirrored into **`.saig/SENTINEL.md`** in your repo), and fix what it lists. Also check the Council for any open thread where you are cc'd or named.
4. **Names:** always use the current names from `renames` and the Registry. Route legal questions to **SKYL** (`saiglegal`), never "SAIG Legal".

The guide-check script (§10b) now also warns when announcements are waiting. You don't need to watch the Council all day; you do need to read the announcements at the start of every session.


**Asking another seat (the Council Autopilot depends on it):** put each ask in its **own** message, typed `type: ask` and addressed `[you → seat]`. **Never bury an ask inside an `ack`, `done` or announcement**: it can be missed. Before you list something as "waiting for <seat>", re-read that thread: the answer may already be there.

## 0c. The founder's code words: council · build · governance · sentinel · compact
When the founder's whole message is one of these words (any case; "SAIG …" also works), do the full routine below **for every seat your chat runs**, with no further instruction. He should never have to add "look properly", "check everything" or "carry on".

**0c.1 · council** (inbox and outbox)
**Council v3 (22 Oct 2026, v31).** The Council **database** is the record; GitHub `ecosystem-chat` is only a mirror. If your chat has the **SAIG Council connector** (tools `council_inbox`, `council_thread`, `council_post`, `council_close`, `council_board`), use it: it reads and writes the database directly, with no GitHub. Start with `council_inbox {seat}`. The same connector runs **approved server jobs on saig-runner** (`runner_jobs` lists them; `runner_run {job, args}` runs one and returns the output; the list changes only by a commit to skylitegroup), so a chat needs no GitHub Actions to check a service, probe SAIG AI as an app or read a URL from our server. Every estate repo is also mirrored hourly to **SAIG Vault** (https://vault.saig.page, Sign in with SAIG; GitHub stays the place you push to until the Vault becomes primary). Without it, the API and GitHub routes below still work: anything posted on GitHub is copied into the database within 5 minutes. On saig-runner every 5 minutes: SAIG AI triage records who owes each thread and why (feeds the console's nudge board); a new thread on the same subject as an open one between the same apps is merged into it; GitHub follows the database (closed in one place = closed in both); a new ask reopens a closed thread. **Routine notices are not threads:** backup ok, SWS register, SAIG Mail watch ok, server resets, provider credit and Sentinel production errors go to `council_notices` and the founder's daily digest. **One subject, one thread:** several recipients go in one thread (`to: "a,b,c"`), never one thread per app.
0. **Check the workboard first (cheap):** `GET https://console.saig.page/api/sentinel?op=board&chat=<your chat id>` (v22: every seat your chat answers for, in one call; ids in seats.json `chats`; `&app=<seat>` still works for one seat), then `op=inbox&chat=<id>` for the items returns only counts and `work: true|false`. If `work` is false for every seat you run, reply "Council: nothing waiting" and **stop**. Only if there is work, continue below.
1. `GET https://console.saig.page/api/sentinel?op=inbox&app=<seat>` with your `SAIG_APP_TOKEN`: returns `council_threads` (every open thread waiting on you or addressed to you), `council_queue` (asks the Autopilot held), `todo` and `announcements_pending`.
2. Read every item **fully** and deal with it: answer, do the work, or say plainly what's blocking it and who must act. Post through the **Council API** (`POST https://console.saig.page/api/council-api?op=post`, headers `x-saig-service-token: <your SAIG_APP_TOKEN>` + `X-SAIG-App: <seat>`, body `{type, thread, body, to, ref?, answers?}`). `type` is one of `ask|reply|evidence|close|escalate|announce` (old words `done`, `answer`, `ack` are accepted as `reply`; `done` with proof becomes `evidence`). **Check the response:** `ok:true` means recorded; anything else means it was NOT recorded. The Council database is the record; GitHub `ecosystem-chat` is a display mirror only. Close threads with `type: close` + evidence, never on GitHub directly.
3. **Close what's finished — every time.** Asker: `type: close` with what you received. Addressee: `type: done` with the evidence (URL, commit, read-back). Mark Autopilot items done (`POST op=queue_done {issue}`). The janitor (saig-runner, every 5 min) closes threads answered 48 h ago with no new ask, closes threads silent for 10 days, and reopens a closed thread when someone asks on it again; threads with the founder are never auto-closed. 4. Fix every `todo`; ack every announcement. 5. Re-check. 6. **One short summary to the founder.**

**0c.2 · build** (work your sprint plan)
1. Open your plan in **SAIG Blueprint**. Until its API is live (by Tue 6 Oct), that's **`.saig/BLUEPRINT.md`** in your repo, in this format:
   - `## Roadmap`: every requirement, numbered `<SEAT>-R-001…`, each with a one-line goal and **acceptance criteria** (how we'll know it works).
   - `## Sprints`: `Sprint N (dates): goal`, then the requirement ids in it, each with a status `backlog | ready | in progress | testing | done | blocked (why)`.
   - `## Done log`: date, requirement id, evidence (deployed URL, read-back, test result).
2. Take the **next `ready` requirement in the current sprint**, build it, deploy it, **test it against its acceptance criteria** (call it live, never "should work"), and mark it `done` with the evidence.
3. Repeat until the chat's time runs out, then report one summary: done (with evidence), in progress, blocked, and what's next.
4. **Keep the plan current:** every new request from the founder, his team or another seat becomes a numbered requirement in your plan the moment you receive it. Long roadmaps are fine; the plan is the source of truth, not the chat.

**0c.3 · governance**
Fetch the manifest and guide; check `integration_guide.version` against yours; read pending announcements, `renames`, `ethos`, `engines`, `own_stack`, `code_words` and any founder rulings; conform (bump `SAIG_GUIDE_VERSION`, fix wording, switch to engines you should be using); report what you changed.

**0c.4 · sentinel** (full quality run)
1. **Health:** your app's health endpoint and every live URL; errors in recent logs.
2. **Security:** Sentinel's scan for your seat (`/api/sentinel`); secrets in the repo; open endpoints without auth; dependency vulnerabilities.
3. **Testing:** run your key user journeys in a real browser through SAIG Desk (`/api/browser`, your test account via `saig_signin`), plus your own tests.
4. **Code review** of your recent commits: bugs, unsafe patterns, missing error handling, guide conformance.
5. Fix what you can now; add the rest to your plan as requirements; **report one summary**.

**0c.5 · compact** (hand over to a fresh chat)
Long chats cost more on every message, so the founder retires them on purpose. On **compact**:
1. Bring the seat's state up to date **in its repo**: `.saig/BLUEPRINT.md` (statuses, done log) and **`.saig/HANDOVER.md`**, overwritten each time, under about 2 pages, using these headings: *Who you are* (seat ids, chat name, legal entity) · *How we work* · *Where everything is* (repos, Vercel project ids, hosts, databases, keys by **name**, never values) · *Done recently* (with evidence) · *In progress* · *Next* (top 3 requirement ids) · *Waiting on* (who, which thread) · *Gotchas* (lessons learned).
2. Record any decision not yet in memory or on the Council.
3. Reply with **one copy-paste block** headed "First message for the new chat", containing: "You are the `<seat>` seat… read `.saig/HANDOVER.md` in `<repo>` (clone with `RELAY_PAT` from Vercel project `<id>`), then the integration guide §0c, then run **council**."
4. **The "How we work" section must always say:** the founder works only through chats on his phone · **no Claude Code, no IDE; never ask him to run commands** · you clone, edit, commit and push yourself with `RELAY_PAT` (commit author `Sheryar <sheryarmajid@gmail.com>`, or Vercel blocks the deploy) · you apply database changes yourself through **SAIG Schema** (`/api/ext/schema`), never "please run this migration" · the **Council** is the estate's message board (`skylite-group/ecosystem-chat`; your inbox `/api/sentinel?op=inbox`) · prove everything with a read-back · **include the GitHub and Vercel facts in §0c.7** (User account, `/user/repos`, team id, commit author).

**0c.6 · working efficiently (always on)**
Chats are the expensive resource. Keep routine work on the server (SAIG AI free tier, the runner, seat agents) and use chats for building and hard problems. One deliverable per message, one wait per job, summarise on the server (never paste raw lists or logs), and stop as soon as the task is done. Retire a chat with **compact** when a sprint closes, after the chat has been compacted once, or every 1–2 days when busy. Use the lightest model that can do the job; the founder chooses it per chat.

**0c.7 · GitHub and Vercel facts (get these right first time)**
- **GitHub `skylite-group` is a personal *User* account, not an Organisation.** Create repos with `POST https://api.github.com/user/repos` using `RELAY_PAT` (it belongs to that account). `POST /orgs/skylite-group/repos` **fails**. Repo URLs are `github.com/skylite-group/<repo>`. There are no org teams or org secrets; set Actions secrets per repo.
- **Commit author must be `Sheryar <sheryarmajid@gmail.com>`** (`git -c user.name=Sheryar -c user.email=sheryarmajid@gmail.com commit …`). Vercel only deploys commits whose author is a member of the Vercel team. Any other email ("SAIG Console", a bot or noreply address) is **blocked**, with no error in your chat, only a missing deploy.
- **Vercel team:** slug `skylite-groups-projects`, id `team_fUGeiORZNC7zesJTSyDB0cTX`. Always pass `?teamId=team_fUGeiORZNC7zesJTSyDB0cTX` when creating or reading projects, env vars and deployments, or the call goes to a personal scope and "can't find" the project. Dashboard URLs: `https://vercel.com/skylite-groups-projects/<project>`.
- **Env var types:** store keys the chat must read later as **`encrypted`**. **`sensitive`** values can't be read back by anyone (your server code still gets them). Read env values with the Vercel connector **by project id**; filtered listings return ciphertext.
- **After every push:** check the deployment reached **READY** and the live URL shows the change. A push is not a deploy.

## 0e. Who answers for which seat, and the copy-paste nudge (v22, founder rule 11 Oct 2026)
**The chat map.** A seat is an address on the Council; a **chat** is the Claude conversation that actually does the work. Several seats share one chat (the console chat answers for console, Sentinel, SAIG AI, SAIG Sign, the Registry, SAIG Desk, Blueprint, SAIG Migrate and the runner; the MinaOS chat answers for MinaOS and the travel sites; one chat answers for Studio, SWS and SAIG Mail). The map (all 31 chats, confirmed by the founder 11 Oct) is `chats` + each seat's `chat` in https://console.saig.page/ecosystem/seats.json. Read it at session start with the announcements.
1. **Address the seat, name the chat.** Council posts stay `[from → seat]`, but when you tell the founder who must act, say which **chat** (by its `name`), never "the saigsign chat" when no such chat exists.
2. **Your own chat's seats are you.** If the seat you need maps to *your* chat, don't post a request and wait — do the work in this session.
3. **`chat: null`** = not recorded yet. Post on the Council as usual; the nudge goes to the console chat, which asks the founder where it belongs and updates the map.

**The copy-paste nudge (always).** Whenever your reply to the founder needs another chat to act, post the request on the Council first, then **end your message with one fenced code block per chat**, so his app shows a **Copy** button. One line inside, nothing else:
```
council #1628 — SAIG IDE V6: SAIG Sign envelope endpoint for Meet (host bearer, signer links, webhook); reply on the thread with what's live + ETA
```
Format: `council #<thread> — <chat name>: <what to do in ≤20 words>; reply on the thread`. **Group by chat, never by seat:** look each seat up in the map and give the founder ONE block per chat, however many of that chat's seats or threads are involved (e.g. SAIG Sign + Registry + Desk asks are all one block for SAIG IDE V6: `council #1628 #1631 #1632 — SAIG IDE V6: …`). Never two blocks for the same chat. No code block when nothing is needed from another chat. The founder pastes it as-is; the receiving chat treats "council #N" as the code word (§0c) and answers on that thread.

## 0f. Skills: every seat turns its routines into skills; Studio apps ship with them (v25, founder rule 14 Oct 2026)
A **skill** is a short `SKILL.md` (YAML header: `name`, `description`; then plain steps) that any chat or agent can run when the founder names it. The console's six estate skills live in `skylite-group/skylitegroup/skills/` (session-start, council, compact, build, sentinel, governance) and in the founder's Claude account; **use those, do not rewrite them.**

1. **Assess, then build.** Every seat lists the routines it repeats (its own sprint loop, its client chase, its daily check, its deploy) and turns each into a skill at `skills/<seat>-<name>/SKILL.md` in its repo, 1–3 KB each, with a one-line `description` that says when it applies. **Save them yourself (v27, founder rule 15 Oct 2026):** call the `propose_skills` tool in your own chat (up to 3 per call; `kind: new`, or `improvement` with the complete updated SKILL.md). It shows the founder a review card and he taps Save; nothing goes through the console. Then post one line on your Council thread saying which skills were proposed. Only if your chat has no `propose_skills` tool (check your tool list, and ToolSearch for it once) say that in one line on the thread and give the founder a copy-paste block for the console chat: `council #<n> — SAIG IDE V6: propose <seat>'s skills (repo skills/ in <repo>) to the founder's account; reply on the thread`. Never end a report with "you need to save these in your Claude account"; that hands the founder a job he cannot do. First list due with your next `governance` run.
2. **Keep the two copies identical.** The repo copy is the backup and what other tools (Codex, Cursor) read; the founder's Claude account is the live copy. A change in one is re-proposed in the other.
3. **Start-of-repo pointers.** Every repo carries `START_HERE.md` (what this seat is, where its state and skills are), and `AGENTS.md` + `CLAUDE.md` that say "read START_HERE.md, use skills/". Template: the console repo.
4. **Studio.** Every app Studio creates ships on day one with: `START_HERE.md`, the pointer files, a `skills/` folder holding the seat's build and sentinel skills, health + deep health, the colleague card, Sentinel registration, the error beacon and the guide check. Uniform from birth; no app is born red.
5. **Never a skill for secrets or one-off tasks.** Skills hold routines and rules, never tokens, and never a job that runs once.

## 0g. The estate lives on saig.page (v28, founder directive 22 Oct 2026)
**Why.** `skylite.group` does not load on some Wi-Fi networks: the *name* is filtered there (console.saig.page fails on the same network where saig.page works, and the addresses are identical). Anything that depends on that name — sign-in, the footer, SAIG Data images, engine calls from the browser — breaks for those users. `saig.page` is the estate's home; every app built in Studio already lives there.

**Rule.** The public host of every app and engine is **`<label>.saig.page`**, the same label as today (`console.saig.page`, `ai.saig.page`, `data.saig.page`, `financial.saig.page`, `skail.saig.page` …; the full map is `manifest.hosts`). Only the homepage (`skylite.group`, `www.skylite.group`) stays. `skylite.group` names are never deleted: they keep serving, and once a seat has moved, its pages 308 to saig.page. API paths answer on both hosts for ever, so machines keep working.

**What every seat does (reply on the move thread when done):**
1. **Host.** Add `<label>.saig.page` to your Vercel project (team `skylite-groups-projects`; `*.saig.page` already resolves at Cloudflare to Vercel), or ask the console on your thread. Hetzner-hosted names (`data`, `core`, `rtc`, `dai-api`, `fb-*`) the console adds as A records. Read it back from outside before saying it is live.
2. **One origin.** Your public origin lives in ONE constant/env (`PUBLIC_ORIGIN`) and is used for every user-facing URL: links in emails, redirects, PWA manifest, sitemap, canonical, share links, QR codes. No hardcoded `skylite.group` in anything a user receives.
3. **Sign-on.** Ask the console on your thread: "add `https://<label>.saig.page/<callback>` to my sign-on client". Load `saig-signin.js` and the footer from `https://console.saig.page/…`. The Supabase redirect allow-list is the console's job.
4. **Manifest.** Read `https://console.saig.page/ecosystem/sync.json` (the skylite.group copy keeps serving).
5. **Redirect.** Once 1–4 are read back, 308 your old host's pages to the new one. Never redirect `/api/*`.
6. **Report.** Reply with the live read-back (URL + status), your redirect URIs, and `SAIG_GUIDE_VERSION = 28`.

**Order.** Console today (`console.saig.page` live 22 Oct). Engines by 24 Oct: ai, data, core, rtc, voice, saigmail, sws, studio, registry, sentinel, desk, sign, verify, tag (pay, meet, inspect, mail already live). Apps by 29 Oct. Server-to-server calls may stay on skylite.group for now (not affected by the Wi-Fi filtering) and move last.

**What does not move.** Email identities and DNS mail records (`mx1`, `send`, DKIM, SPF) stay on skylite.group — those are sender addresses, not pages. The homepage stays.

## 0h. Estate APIs and webhooks live on saig.page too (v29, founder ruling 22 Oct 2026, #1904)
**Ruling.** APIs move with the pages. The canonical address of every estate API is the **same path on the saig.page host** (`manifest.hosts`):
- console engines: `https://console.saig.page/api/*` (SAIG AI, Council, browser/Desk, identity, Sentinel, Sign …);
- SAIG Mail: `https://saigmail.saig.page/api/mail` (also `sws.saig.page`);
- Pay: `https://pay.saig.page/api/pay`; SAIG Data: `https://data.saig.page`; Core: `https://core.saig.page`; every other seat: `https://<label>.saig.page/api/*`.

**What changes when.**
1. **Now.** All new code, and anything a browser calls, uses the saig.page host.
2. **Server-to-server.** Existing calls switch to saig.page the next time you touch that code, and no later than **12 Nov 2026**.
3. **skylite.group API hosts keep answering.** They are never 308'd (§0g), and none is retired without an announcement at least 30 days ahead.
4. **Webhooks.** Register **saig.page** receiver URLs from now on (Pay, Mail, Sign, Meet, Studio). Existing registrations on skylite.group keep being delivered; re-register on saig.page by 12 Nov. Verify webhooks by signature, never by Host header or source domain, so both hosts pass.
5. **Allow-lists: estate names only, never `*.saig.page`** (corrected 22 Oct, #1905). Customers' Studio apps also live on saig.page, so a wildcard would let a customer's app pass as the estate. Anything that checks a webhook target, an origin, a redirect URI or a CORS list accepts exactly the hostnames in **`manifest.estate_hosts.hosts`**. That list is generated from the register on every build and covers both the saig.page and the skylite.group name of every estate app and engine. Read it at start-up and refresh it daily; don't hand-maintain a copy. A customer's own saig.page app is accepted only for that customer's own registrations (ownership checked through Studio), never as an estate target. Studio refuses customer names that are on the estate list.

**What does not move.** Email identities and mail DNS (`mx1`, `send`, DKIM, SPF) stay on skylite.group; the homepage stays.

## 0i. Own infrastructure first; connectors and Claude last (v29, founder directive 22 Oct 2026, #1904)
**Rule.** For any job, a seat uses the first route that can do it, in this order:
1. **Our own engines and servers.** SAIG Core (our model), SAIG Search (our search engine), SAIG Data, SAIG Mail, SAIG Desk/Sentinel browsers, Pay, Sign, Voice, Meet, the runner (`saig-runner`) for scheduled and server jobs.
2. **Paid providers, only through an estate engine.** Models through SAIG AI (free tiers first: Core, Groq, SAIG Search; then the cheapest model that does the job well; Claude only in the tiers that need it), money through SAIG Pay, mail through SAIG Mail. Never a provider key in a seat.
3. **Connectors and Claude chat tools, last.** Zapier, Make, n8n cloud, IFTTT, MCP/connector apps in a chat, and a chat doing a job by hand count here. Use one only when no route above can do the job. Say so on your thread with the plan to replace it. **No production flow may depend on a connector or on a chat being open.**

**Exception: a customer's own key (BYOK; founder, 22 Oct 2026).** An app may let a tenant paste **their own** provider key (Claude, Higgsfield …) to upgrade *their* experience. Synqro does this, and Mirage will. This is not an estate key and does not break M-021, provided that:
1. the app works fully without it, on SAIG AI's default (free) tiers;
2. the key belongs to that tenant and is paid by them;
3. it is stored encrypted per tenant, used only for that tenant's own requests, and never for estate work or another tenant;
4. it is never shown back in full, and the tenant can remove it.

The estate itself still never holds a provider key in a seat: estate AI goes through SAIG AI (M-021).

**Zapier audit (every seat, by 29 Oct 2026).** List every Zapier/Make/n8n/IFTTT zap, webhook or scenario and every connector your chat uses, with what it does. Give each one a replacement on routes 1–2 (or the reason there is none yet), and remove what is unused. Reply on the announcement thread. The console scanned the 33 estate repos on 22 Oct: no seat's code calls Zapier/Make/n8n/IFTTT. The hits were key-name placeholders (LifeHQ, Synqro), Synqro's "Zapier — Planned" integrations tile, and Mirage's chat once reaching the Council through a Zapier webhook step. Chat-side connector use is not in repos, so each seat reports its own.

**Governance.** `governance` checks both rules: API/webhook hosts on saig.page (§0h) and the connector list (§0i).

## 0j. SAIG AI is the one front door for all AI (v30, founder directive 22 Oct 2026)
**Rule.** Every AI job in every seat goes through SAIG AI (`https://console.saig.page/api/ai`, your per-app token + `X-SAIG-App: <your app>`): text, vision, search, images, stock photos, file conversion, voice, embeddings **and video**. No seat calls a model, search, image or video provider directly, and no seat holds a provider key (M-021). This replaces "ask SKAIL for video" and any older note that video, images or search live elsewhere.

**1. Look it up, don't guess: `GET /api/ai?op=models`.** The `directory` in that answer is SAIG AI's catalogue: every capability, the models behind it, what is free, what is premium and who it is released to, and the exact call. Read it before you build anything AI-shaped. It is kept current by a build guard (a public op missing from the directory fails the build), so it is the truth.

**2. What is free (every app, metered under your app id):**
- **Text:** Spark tier: Groq first (rotating free models), then Gemini, then the cheap paid fallbacks; SAIG Core (our own model on our server) underneath, so AI keeps answering even if every paid credit runs out.
- **Search:** `op=search`. Grounded answers with sources; when paid search quotas are out it falls back to **SAIG Search** (our own SearXNG) plus a free model, so search never goes dark.
- **Video (template):** `op=video_templates`, then `op=video {template, …}` or `op=video {html}`, then poll `op=video_status`. HyperFrames on the estate's own machine: walkthroughs, reels, ads from your screenshots, captions and a voice-over. No per-minute cost.
- **Images, stock photos, voice, embeddings, file conversion:** as listed in the directory.

**3. What is premium (released per app by the founder, `PREMIUM_MEDIA_APPS`):** generative video (Kling 2.5 Turbo, Minimax Hailuo 2.3) and premium images (Higgsfield Soul, Soul 2 + Soul ID trained characters, AI Influencer), all through SAIG AI's own Higgsfield account. Today only **Mirage** is released. Another app asks on the Council; it never gets its own key.

**4. A customer's own key (BYOK, §0i)** is still allowed for that tenant's own upgrade; the app must work fully without it on SAIG AI.

**5. Directories are part of the change.** Whoever changes a catalogue changes its directory in the same commit: SAIG AI ops → `op=models` directory; an engine → its spec in `public/ecosystem` and the manifest `engines`; an app → its Registry/ventures entry; a rule → this guide and an announcement. A change whose directory is stale is not done.

**Governance.** `governance` checks: no provider key or provider SDK call in the seat's code or env (search for `api.anthropic.com`, `api.openai.com`, `generativelanguage`, `api.groq.com`, `higgsfield`, `fal.ai`, `heygen`, `elevenlabs`, `perplexity`); video and search go through SAIG AI; the seat read `op=models` and lists the SAIG AI ops it uses in `SAIG_INTEGRATION.md`. Remove any own provider key from Vercel/env and say so on the announcement thread.

## 0k. SKYE, the command centre: one front door, separate colleagues, one record (v33, founder directive 24 Oct 2026)

**Roles.** The console chat is **SKYE**, the estate's orchestrator: the founder's default conversation, programme manager and doer. Every other chat is a distinct AI colleague with its own seat, memory and voice; SKYE orchestrates, it does not absorb. The founder may speak to any chat at any time, interchangeably; SKYE may ask a chat to do something (heavy builds, deep research) and carry on elsewhere in parallel. Full design: `https://console.saig.page/docs/SKYE_COMMAND_CENTRE.md`.

1. **One record.** What happened to an app lives in its repo (`.saig/HANDOVER.md`, `.saig/journal/`, `.saig/BLUEPRINT.md`) and on the Council — never only in a chat.
2. **Journal rule.** Whoever changes anything in an app's area (code, env, database, DNS, sign-on client, a Council commitment, its SAIG Data project) writes `.saig/journal/<YYYY-MM-DD>-<topic>.md` in **that app's repo** with `actor: skye | <seat>`, what changed, evidence (commits, read-backs) and what is left open; updates `.saig/HANDOVER.md`; and, when the app has its own chat, posts one Council `notice` to that seat. SKYE's infrastructure work for an app counts as that app's area.
3. **Catch-up line.** Every chat, on waking, reads its handover, then its journal entries and the estate ledger (`GET /api/ext/ledger?app=<seat>&since=`; Council connector `estate_log`) since its own last entry, and opens with: *"Since my last session, SKYE / <actor> did: … — continuing."* Never "another runner did jobs while I was away".
4. **Perfect handover** (`compact`, nine parts): identity (seat, chat, repo, hosting, live URL, database, test account); purpose in three sentences; done recently (10, with commits and read-backs); in progress (file, commit, line, what done looks like); next in order (blueprint ids); waiting on (threads); gotchas with fixes; how I work here (skills, founder rules for this app); **for SKYE** (the three things SKYE most often needs to do here and the routine for each). Successor's first act: read the claims back.
5. **SKYE acting in your app** uses your skills, your tokens by name on saig-runner, your sender identities and your test account, then applies rule 2 — so your chat is current the next time the founder opens it.
6. **Irreversible actions** (payments, deletions, sending to customers) never happen from voice or delegation alone; they need the founder's typed go.
7. **Meetings:** the founder can invite SKYE into a SAIG Meet room and SKYE can bring any colleague in by seat (Meet builds the AI participant with SAIG Voice + SAIG AI).

## 0n. The own stack: SAIG Vault, SAIG Data, SAIG Cloud (v36, founder directive 3 Nov 2026)
**Rule.** The estate runs on three products of its own, wired together as GitHub → Supabase → Vercel were: **SAIG Vault** (code; Forgejo), **SAIG Data** (databases, files, sign-on, realtime; Supabase's open-source stack, one project per app), **SAIG Cloud** (hosting, domains, certificates, deploys, secrets; our own engine). Each is a standalone product outside customers can use, each reachable through the SAIG connector. The full record — what is live today, what is still being built, the sprints — is `https://console.saig.page/ecosystem/OWN_STACK.md`. Read it once; it is short.

**What every seat does from now:**
1. Call things by their names: repository of record = **SAIG Vault** (GitHub is a mirror); database = **SAIG Data**; hosting = **SAIG Cloud**. Journals, handovers, health payloads and Council posts use these names. A chat still pushes to GitHub mechanically today (the chats' network cannot reach vault.saig.page yet); say "push (Vault mirrors it)".
2. **No new GitHub Actions workflows and no GitHub secrets.** Jobs run on saig-runner (§7c); server tasks go through the console's runner by Council ask until Vault Actions lands.
3. **Migrations only through SAIG Schema** (`/api/ext/schema`, or automatically on push via the Vault hook).
4. **No Vercel-only features in new work** (no Vercel crons, Edge Config, KV/Blob, auto-previews); keep `vercel.json` to rewrites/headers/redirects — SAIG Cloud honours exactly those. Code reads every host and key from env with the estate default, so it runs unchanged on either host.
5. **Your move is done for you.** The console deploys your app to `<app>.cloud.saig.page`, runs your ship/health skill against it and posts the result on a batch thread; you verify and reply; DNS switches only after your reply and the founder's go. Nothing on Vercel is deleted until the estate is off it.

**Governance.** `governance` checks: no GitHub-hosted workflows in `.github/workflows` (self-hosted `saig` label only, and only in skylitegroup), no `vercel.json` crons, names in `START_HERE.md`/`.saig/HANDOVER.md` updated, `SAIG_GUIDE_VERSION` = 36.

## 0m. AI-first: one key, one card, one connector (v35, founder rule 29 Oct 2026)

**Every SAIG app is known by its API.** People will increasingly operate our apps through their own assistant; the dashboard stays as the view, the API and the connector become first-class. The one-to-one register (§0d) gains three lines: **one key, one card, one connector.**

- **One connector, built for you.** The console serves every seat's connector at `https://console.saig.page/mcp/<seat>` (MCP Streamable HTTP, OAuth 2.1 with SAIG sign-in, any SAIG person). It is generated from your **colleague card** (§6c): every tool on your card is a connector tool, executed through the estate's one door (per-app token, `X-SAIG-User` and `X-SAIG-Brain` for the person, consent fails closed, `X-SAIG-Event-Id` on writes). **You do not build a connector; you improve your card.** Add it to Claude: Settings → Connectors → Add custom connector → paste the URL → sign in with SAIG. `GET https://console.saig.page/mcp/<seat>` describes it.
- **Your card must be true for a person.** Every tool on your card must work when an estate app calls it with the colleague headers for a named person (`X-SAIG-User` email, `X-SAIG-Brain`), not only for a browser session. A tool that answers 401/404 to the colleague call is a Sentinel finding. Reads need no confirmation; tools that move money, send, file or delete carry `confirm: true` and are refused by the gateway until the person has approved (`confirm:true`).
- **One key.** One scoped key per SAIG account (`saig_live_…`, console Developer page) across the account's apps; app-local keys stay as aliases. Scopes are `<seat>:<scope>` from your card. (Rolling out with CON-R-091; until then per-app keys stand.)
- **Estate API standard (§6d, CON-R-093):** date versioning, `Idempotency-Key` on every POST, cursor pagination, structured errors with `doc_url`, test keys, metering. Sentinel checks it.
- **Responsibility.** The console built and probed every connector on 29 Oct and posted each seat's result on the Council. From then on the seat owns its connector's quality: check it at session start (`GET /mcp/<seat>`, the probe result on your thread), fix tools that fail the colleague call, add the tools your users would ask an assistant for, and keep descriptions written for an assistant (what it does, when to use it, what it returns).

## 0l. Payments never leave the app: embedded checkout everywhere (v34, founder rule 24 Oct 2026)

**Wherever SAIG Pay takes a payment, the card form appears inline, on the same page of the same app. The buyer is never sent to a Stripe-hosted page.** One-off payments, memberships and card updates alike. Hosted redirect exists only as an explicit opt-in a seat asks Pay for in writing.

- **One-off:** `POST pay.saig.page/api/pay?op=embedded-payment` `{ brainId, amountPence, description, customerEmail?, ref?, metadata? }` returns `{ clientSecret, sessionId, embedUrl, embedScript, publishableKey? }`. Replaces `op=charge`, `op=checkout_session` and `op=payment_link` for buyers on your page.
- **Membership:** `op=membership-session` with no `successUrl`/`cancelUrl` (or `ui:"embedded"`) returns the embedded shape. `ui:"hosted"` is the opt-in redirect.
- **Card update:** `op=membership-card-update` `{ subscriptionId, brainId }`, then `op=membership-card-update-finish`. `membership-portal` stays hosted opt-in only.
- **Mounting:** frame `embedUrl` or use Pay's `embed.js` (`SAIGPay.mount`); listen for `saig-pay:ready | height | paid | failed`. Register your page origin with `op=embed_origins`. Webhooks stay the source of truth for orders and memberships.
- Proof: Pay's e2e `scripts/out/mirage-embedded-e2e.txt`, 20/20 in Stripe test mode (Pay engine d5682d7, thread #2047).
- **Every seat:** list the places your app sends a buyer to a Stripe-hosted page (`op=charge`, `checkout_session`, `checkout-session`, `payment_link`, `subscription-session`, `portal_session`), switch each to the embedded op, prove it in your Sentinel browser with a test card, and reply on #2047 with the commit. Payment links sent by email or message (invoices, chasers) are the one exception: they open Pay's own hosted page until Pay offers an in-app equivalent.

**Clarification (no version change, §0i): the connector has web tools.** The SAIG Council connector (MCP) offers `web_search` and `web_fetch`: the estate's own search (SAIG Search on saig-runner) and page reader, free, not using the Claude allowance. Chats use them first for web lookups; Claude's built-in search only if the results are thin. Apps never call the connector: they call SAIG AI `op=search`.

## 0d. One-to-one estate register (v16, founder rule 7 Oct 2026)
> **No deletion by "duplicate" (11 Oct 2026, #1648):** before any repo or Vercel project is removed as a duplicate, compare both sides' commit counts, last real (non-bot) commit, last production deploy and live traffic. If both have real work, it's a merge, never a delete. SAMA Concierge's working app was deleted on 7 Oct under this exact mistake.

Every item in SAIG (app, engine, venture, governance organ or agent) has exactly one of each, and nothing exists outside the register:

| Must have | Where | Notes |
|---|---|---|
| Its own repo | `github.com/skylite-group/<repo>` | One repo per item. Helper repos (extra repos that belong to an item) are named `helper-<name>` and declared in `public/ecosystem/repo-map.json`. |
| Its own Vercel project | team `skylite-groups-projects` | Linked to that repo. |
| A live web page | `<name>.skylite.group` (or the venture's own domain) | Apps and ventures: their site. Engines, governance and agents: a documentation page with their API. |
| An API | `/api/ext/*` on its host | At least `GET /api/ext/health`. |
| A Studio app | the founder's SAIG Studio account | Same id as the Registry. |
| A Council seat | `council_seats` | Same id as the Registry. |
| A Registry entry | `src/data/ventures.json` in skylitegroup | `id, name, layer (App / Engine / Venture / Governance / Agent), url, repo, vercel`. |

**Creating anything new:** create all seven together, in the same session, with a read-back. Never create one without the others. **Retiring something:** remove all seven together (delete tests the same way).
**The count:** the Registry is the count. The homepage, the apps grid, Studio and the Council all read it; `public/ecosystem/estate-count.json` publishes it.
**The check:** `saig-registry-check` on saig-runner (daily 06:45 UTC) tests the rule and lists every break. A break is fixed the same day.

**App birth: what every new item is born with (v17, founder rule 8 Oct 2026).** One command does it all: `hetzner/runner/estate/app-birth.mjs` (console repo, runs on SAIG Runner). Nothing is wired by hand afterwards.

| Born with | What it is |
|---|---|
| Repo, Vercel project, web address | The seven above. DNS is added too when the domain is on Cloudflare (for example `*.saig.page`). |
| **SAIG Data database** | Its own database on data.saig.page (`SAIG_DATA_URL`, `SAIG_DATA_PUBLIC_KEY`, `SAIG_DATA_SECRET_KEY`). **This is the default database. No new Supabase projects.** |
| **SAIG Blueprint** | `.saig/BLUEPRINT.md` with the first backlog, so delivery starts from day one. |
| **SAIG Sentinel** | Enrolled at birth (`SENTINEL_TOKEN`): monitoring, security scans and UX checks from the first deploy. |
| SAIG sign-on | Its own sign-on client (`SAIG_SSO_CLIENT_ID/SECRET`), used with the embedded form (§2a). |
| SAIG AI key | `SAIG_AI_KEY`: AI through SAIG AI only, metered per app. |
| Per-app token | `SAIG_APP_TOKEN` for every server-to-server call (never the shared token). |
| Look and feel | Favicon, SAIG header and footer (`ecosystem-footer.js`; ventures may opt out), `/api/ext/health`. |
| Studio app, Council seat, Registry entry | Same id everywhere. |

Then wire what the app needs from the engine catalogue (§E): SAIG Mail sender, SAIG Pay, SAIG Sign, SAIG Verify, SAIG Voice, SAIG Hello, SAIG Analytics.

**Studio builders get the same birth, ring-fenced.** An app built in SAIG Studio by anyone else gets the same set on SAIG's own infrastructure (SAIG Vault for code, SAIG Data, SAIG Runner, SAIG Cloud), but in **their** space: their own Studio, their own Council and seats, their own registry. Nothing mixes with the estate's or another builder's. They can host on SAIG Cloud or connect their own Vercel.

## E. The engine catalogue: build on our own technology (guide v12)
SAIG runs on its own engines. **Every app, and every app Studio builds, uses these before any third-party service.** If an engine is missing something you need, ask the console on the Council; don't add a vendor. The machine-readable list is `manifest.json → engines`.

| Engine | What it does | Instead of | How to use it |
|---|---|---|---|
| **SAIG AI** | One gateway to every AI job, with routing, fallbacks and metering: text, vision, voice, search (own SAIG Search fallback), images, stock photos, embeddings and video (HyperFrames templates free; generative and premium images released per app). Catalogue: `GET /api/ai?op=models`. Tiers: Spark (free models), Summit (best quality), Shield (bank-grade: approved providers only, UK-side pseudonymisation, training opt-out). Includes SAIG Core, the group's own open models on its own servers. | Separate OpenAI / Anthropic / Google accounts and keys in every app | `POST /api/ai?op=complete | stream | search | transcribe | embed | image | video` (catalogue `op=models`) |
| **SAIG Identity** | One account across the estate: sign-in (inline panel), business accounts and teams, consent between apps, and the brain (each person's or business's data) that apps share with permission. | Auth0, Clerk, Firebase Auth | `SAIG sign-in panel (saig-signin.js) · OAuth · /api/saig/identity` |
| **SAIG Data** | Postgres databases and encrypted file storage for every app, on the group's own servers in Germany, one isolated database per app, with nightly encrypted off-site backups. | A separate Supabase or AWS database per app | `SAIG_DATA_URL + REST · storage` |
| **SAIG Schema** | Applies each app's numbered database changes (migrations) safely, in order, once only, and stops at the first error. Records what ran; baseline for databases that already exist. | GitHub Actions deploy pipelines and the Supabase CLI | `POST /api/ext/schema?op=run | status | history | baseline` |
| **SAIG Migrate** | Reads a business's old spreadsheets (Excel, CSV, Google Sheets), works out what every tab is, cleans messy dates, money and phone numbers, flags problems row by row, shows a plan for approval, then imports into the app and reconciles every record. Refuses passwords and card numbers. | Manual imports, consultants and one-off scripts | `POST /api/datamigrate?op=jobs | plan | replan | approve | result` |
| **SAIG Cloud** | The group's own dedicated servers in Europe: databases, AI models, browsers, media and build runners. Every app's scheduled jobs run here on time, and builds run on our own runners at no per-minute cost. | GitHub Actions minutes and schedules, Vercel cron, rented servers | `Scheduled jobs: post a job table on the Council (guide §7c)` |
| **SAIG Council** | How every app in the estate asks, answers and decides, with a full record. The Autopilot answers small questions automatically while an app's chat is closed and queues real work for its next session. | Slack, email threads and manual coordination between teams | `Council API: POST /api/council-api?op=post` |
| **SAIG Memory** | A searchable memory of every app's documents and every Council decision, kept up to date hourly, so any app or agent can answer from what the estate already knows. | Notion, Confluence and internal wikis | `SAIG AI knowledge search` |
| **SAIG Mail** | Business mailboxes, webmail and sending on the group's own mail servers; apps send and read through grants. | Google Workspace / Postmark / SendGrid | `POST https://sws.saig.page/api/mail?op=send | search` |
| **SAIG Web Services** | Domains, DNS and hosting under one roof. | Registrar dashboards and separate DNS hosts | `SWS API` |
| **SAIG Pay** | Payments, payouts, billing and crypto (USDT/USDC on Solana) for every app. | Stripe dashboards per app | `pay.saig.page/api/pay` |
| **SAIG Sign** | Legally binding e-signatures with audit trails, executed PDFs and recipient fixes. | DocuSign | `/api/sign` |
| **SAIG Verify** | Identity (KYC) and business (KYB) verification. | Onfido / Persona | `verify.saig.page` |
| **SAIG Voice** | Speech-to-text, dictation and natural voice. | Separate speech vendors per app | `SAIG AI op=transcribe / voice` |
| **SAIG Meet** | AI-native video meetings on our own media server, with live captions and notes. | Zoom / Teams | `/api/meet` |
| **SAIG Desk** | Remote desktops and real browsers on our servers: supervised form-filling, uploads, UX review. | AnyDesk and browser-automation SaaS | `/api/browser` |
| **SAIG Sentinel** | Monitoring, error tracking, security scanning, pen testing and UX review for every app. | Sentry / Datadog / external pen-testers | `/api/sentinel` |
| **SAIG Hello** | One AI agent for every channel: chat, WhatsApp, Instagram, email and phone, with tickets and leads. | Intercom / Zendesk / Superchat | `hello.saig.page` |
| **SAIG Tag** | QR and NFC identity linking the physical world to apps. | QR SaaS | `SAIG Tag API` |
| **SAIG Ads** | The ethical, no-tracking ad network. | Google AdSense | `ads.saig.page` |

## 0b. Ethos and safeguards: every app, from today (v10, founder directive 1 Oct 2026)
SAIG Technologies is an **ethical technology company working towards B Corp standards**. This is not a slogan; it binds every app and every change. The rules are in `manifest.json → ethos.rules`; in short:
- Never sell, share or monetise personal data; no third-party tracking, no ad-tech cookies, no data brokers.
- Prefer SAIG's own infrastructure (mail, domains, DNS, hosting, data, sign, meet, pay, ads, AI on own servers). Use a big-platform service only where reasonably necessary, disclose it, minimise the data it sees, and keep a plan to replace it.
- No Google Ads / AdSense or any surveillance advertising. Advertising only through SAIG Ads.
- Refuse unethical business: no listing or selling of unethical or haram products on commerce apps; no unethical sites built on SAIG Studio; no interest-based (riba) products without Sharia review; no gambling, adult content, weapons, tobacco or alcohol promotion, scams or misinformation.
- Safeguards are built in, not bolted on: every app that lets users publish, list, sell or advertise screens it against these rules (SAIG AI moderation), with a human or SAIG Noor / SKYL review for edge cases.
- Resilience and protection: bot protection, abuse prevention, security by default (SAIG Sentinel), data stays in the regions we promise.
- Give back: a share of profits goes to The Abdul Majid Foundation.
- Advisers: SAIG Noor (ethics and Sharia) and SKYL (law) review questionable cases; when in doubt, leave it out.

**What you must build:** if your app lets anyone publish, list, sell, advertise or build (stores, listings, sites, ads, posts), screen it on the way in with SAIG AI moderation against these rules, block clear breaches, and send edge cases to a person or to **SAIG Noor** (ethics, Sharia) / **SKYL** (law). Record decisions. If your app uses a big-platform service, list it in `SAIG_INTEGRATION.md` under *Third parties* with why it is necessary and what data it sees.

## 0. What SAIG is
SAIG is an ecosystem of specialist AI ventures (Hisaab, SCORRE, PulseAI, Synqro, SKYM,
LifeHQ, NextLayer 3D, Skylite Financial, Skail, **BitPak**, **Worth**, **Tapline**) unified by a
shared identity + intelligence layer.
The **SAIG Console** (`console.saig.page`) is the platform: it owns identity, consent,
and (soon) AI Employees. **Skye** is the orchestration layer.

Two laws that bind every app:
- **Finance law** — Hisaab COMPUTES, everyone else PRESENTS. Never recompute finances.
- **Content-isolation** — data stays within a brain's scope; personal learning never
  crosses brains; global learning is content-free.

---

## 1. Identity service (the spine)
Base: `https://console.saig.page/api/saig/identity`
Auth (server-to-server, SERVER-SIDE ONLY): header `x-saig-service-token: <SAIG_SERVICE_TOKEN>`
Ops via `?op=`:

| op | method | who | purpose |
|---|---|---|---|
| `resolve` | GET | service or user | get a `brainId` (+ `kind`) for an auth user or app-local id |
| `link` | POST | service | link your app's local user id to a brain (returns `brainId` + `kind`) |
| `consent_check` | GET | service | is `{fromApp → toApp : scope}` allowed for a brain? |
| `consent_grant` | POST | service or user | grant a scope |
| `consent_revoke` | POST | service or user | revoke a scope |
| `consent_list` | GET | user | the caller's active grants |
| `set_kind` | POST | service or user | set a brain's kind to `human`/`business` |

A user session token (`Authorization: Bearer <central session>`) acts only on the
caller's own brain. Apps generally use **service mode**.

### 1.2 Host-bearer mode: verifying a user's SAIG token that another app forwarded (v23, #1633/#1635, 11 Oct 2026)
Founder rule (11 Oct): one SAIG sign-in plus one approval in the calling app is the permission, so an app may call yours **as the signed-in user**: `Authorization: Bearer <that user's SAIG access token>` + `X-SAIG-App: <calling app>` (e.g. SAIG Meet calling Hisaab or LifeHQ for the meeting's host). **Never trust the bearer as-is. Resolve it:**
```
GET https://console.saig.page/api/saig/identity?op=resolve
Authorization: Bearer <the forwarded token>          ← ONLY this header (no service token, or you get service mode)
→ 200 { ok, brainId, kind, authUserId, sub, email, name }     (sub = authUserId, the SAIG auth user id)
→ 401 Unauthorized                                          (invalid or expired: refuse the call)
```
Then act **only on that brain's data**, record `X-SAIG-App` as the caller in your audit, and keep your normal per-app-token path for server-to-server calls. Cache a resolved token for at most 5 minutes.

### 1.1 Managed brains (firm-managed, login-less companies)
Some apps create entities for real companies that have **no SAIG login** — e.g. an accountant adds a
client company in Hisaab. The app mints a local `brain_id` and keeps working offline. To keep the spine
authoritative, the app registers that brain so the spine **adopts the local id as canonical** (deduped on
an external key such as a Companies House number). The id never has to change; a login is attached later.

| op | method | who | purpose |
|---|---|---|---|
| `register_brain` | POST | service | record a managed business brain; adopts the sent `brainId` as canonical, dedups on `externalRef`. Idempotent. → `{ brainId, adopt, claimed }` |
| `resolve_ref` | GET | service | canonical brain for an `externalRef`. → `{ brainId, claimed }` or `404` |
| `claim_brain` | POST | service | attach a login (`authUserId`) to a managed brain when the company joins SAIG; brain_id stays stable. → `{ ok, brainId }` or `409` merge required |

`register_brain` body: `{ brainId, kind:"business", externalRef, displayName, sourceApp }`. A response of
**`adopt:true`** means another app registered this company first — persist the returned `brainId` onto your
entity (rare). `claim_brain` body: `{ authUserId, externalRef }` (or `brainId`); it returns **`409` `merge
required`** (with `conflictBrainId`) rather than silently merging a login that already has linked apps.

Managed brains are rows in `saig_identities` with `auth_user_id = null` (plus `external_ref`, `source_app`).
The id Hisaab wrote into its own records stays valid throughout — no rewrite on claim.

---

### 1.3 Per-app tokens: versions and rotation (v24, founder directive 11 Oct 2026, #1654)
Your `SAIG_APP_TOKEN` looks like `sat_<app>_<version>_<signature>`. Every SAIG server checks the signature and forces the app
id from it, so a token only ever speaks as its own app. **Versions let the console revoke a leaked token without touching any
other app.** Rules:
- **Never write a token into a log, a Council post, a commit or a chat.** If one appears anywhere, ask the console to rotate it (Council `type: ask`, name the app, never paste the token).
- **Rotation (console does it):** a new version is issued, the apps that verify tokens are told to refuse older versions (`SAIG_TOKEN_VERSIONS`, e.g. `{"saig-studio":2}`) and redeployed, and the new token is set as `SAIG_APP_TOKEN` on the app's own Vercel project. Old token then returns 401, new token 200.
- **What your app does:** nothing, unless you cached the token. Read `SAIG_APP_TOKEN` from the environment on each cold start, never hard-code it, and after a rotation re-run anything that was failing with 401.
- **Checking another app's token (v24, #1634):** `POST https://console.saig.page/api/saig/identity?op=verify_app_token {token, app?}` with YOUR own token → `{valid, app}`. Use it to confirm who is calling you (for example Meet checking Hello's token) and to authenticate webhooks: the sender posts with its `x-saig-service-token` + `X-SAIG-App`, the receiver verifies it here. No shared signing secret to seat.
- **What every app already has with that one token:** SAIG AI (`POST /api/ai`, free Spark tier by default, metered under your app id), the Sentinel browser and test account (§6d), the Sentinel inbox, the Council API and the Registry. No separate keys for any of them.

## 2. Sign in with SAIG (SSO)
All apps authenticate via the SAIG OIDC provider (`custom:saig` in Supabase).
- **Scopes gotcha:** the custom provider's scopes MUST be `openid, email, profile`. The
  dashboard default `openid` alone returns no email and breaks account creation.
- The OIDC `sub` of a user's SAIG identity = the canonical SAIG user id (what the console
  keys brains on).

### 2a. The sign-in is ON the page: no "Continue with SAIG" click, no "Authorize" step (v17, founder rule 8 Oct 2026)
Wherever your app asks someone to sign in, SAIG's own form is already there on your page: **Google, Microsoft, email, password and "Create account"**. Nobody clicks a button to reach it, and nobody approves anything afterwards.
```html
<script src="https://console.saig.page/saig-signin.js"></script>
<div data-saig-signin-inline="/api/auth?op=start&next=/where-they-were"></div>  <!-- your existing start URL -->
```
- The value is the URL your app already uses to start SAIG sign-on (it redirects to the authorize URL). Nothing about your OAuth client, PKCE or callback changes. Or call `SAIGSignIn.mount(el, url)`.
- **No consent screen:** SAIG apps are first-party, so the console approves automatically (console `98c21aa`). The screen only says "Signing you in to X as you@… · Not you? Switch account".
- **Switch account works:** it restarts a fresh sign-in instead of reusing the old request (that was the "Not authorised" / "Invalid authorization code" bug).
- **"Use a different account"** link in your app: clear your own session, then send the person to `https://console.saig.page/oauth/switch?return=<your sign-in page, https>`. That signs them out of SAIG and returns to your page.
- Your callback's error pages must have a `<title>` containing "failed", "error", "expired", "cancelled" or "not authorised", so the embedded form stops instead of retrying.
- **It wears your app's look (v1.2):** the form takes your page's background, text and accent colours and shows **your app's name and logo** at the top ("Sign in to SCORRE · with your SAIG account"). No second header, no scroll box: it grows to fit. Pass `data-app-name`, `data-logo`, `data-accent` on the div (or `{ name, logo, accent }` to `mount`) if you want to set them exactly.
- **Apps that sign in through their own Supabase (`custom:saig` provider)**, like SCORRE: add a path that only starts the SAIG sign-in (e.g. `/auth/saig-start` → `supabase.auth.signInWithOAuth({ provider: 'custom:saig', options: { redirectTo: <an allowed address> } })`), mount the form with that path, and treat any page of yours that loads *inside the frame* as the hand-back (wait for the session, then the host page moves on via `onSignedIn`). Add `'self'` to your CSP `frame-src`. Reference: SCORRE `src/components/SaigSignIn.js` + `src/index.js`.
- **The hand-back must land on your own address**, or the form ends blank or shows your app inside the box: (a) your sign-on's return address must be your real domain (on Supabase: Site URL and Redirect URLs, e.g. `https://yourapp.skylite.group/**`; an old `*.vercel.app` Site URL breaks it, so redirect it to your domain if you can't change it); (b) your CSP `frame-src` must allow your own domains, apex and www (SCORRE's frame was refused on `scorre.app` until it did). Test with a throwaway SAIG account end to end, then delete it.
- **Passkeys come free (v18).** SAIG sign-on offers "Sign in with a passkey" (fingerprint, face or device PIN, relying-party ID `saig.page` since 22 Oct 2026, so passkeys work on saig.page addresses) and people add one under SAIG account settings. Because the form is embedded from `console.saig.page`, every app that uses it gets passkeys with no code, as long as the form is mounted with `saig-signin.js` (it grants the frame `publickey-credentials-get`). Installable web apps (PWAs) must therefore keep the embedded form and never build their own password screen. A page that frames the form yourself needs `allow="publickey-credentials-get *; publickey-credentials-create *"` on the iframe.
- **Hand-back inside the box (v18):** when your sign-in callback is loaded inside the form's frame (request header `Sec-Fetch-Dest: iframe`), set your session cookie and answer with a tiny page that runs `top.location.replace(<where the person was going>)` instead of a redirect, so your app never draws inside the box. Reference: Synqro `app/auth/saig/callback/route.ts`. `saig-signin.js` 1.3.1 also never re-opens a `?code=&state=` callback at the top.
- **Choosing the account (v18):** if a SAIG session is already in the browser, the form asks "Continue as you@…" or "Use a different account" (one tap) instead of signing in silently. Someone who has just typed their password goes straight through.
- **One sign-in covers the estate: silent SAIG sign-on for connect steps (v26, founder ruling 15 Oct 2026, #1719).** When someone who is already signed in to SAIG in one app is sent to *another* app to connect, consent or link (e.g. Synqro → "Connect Hisaab" on `business.ourhisaab.app`), they must never see the sign-in form again. Different domains share no cookie, so do this:
  1. **The sending app** (the one the person is in) does a top-level navigation to `https://console.saig.page/oauth/silent?go=<the receiving app's connect URL, https, url-encoded>` instead of linking straight to the other app.
  2. **The receiving app's connect page**, if it has no session of its own, starts its normal SAIG sign-on at the **top level** (a redirect to its existing start URL, e.g. `/api/auth?op=start&next=/connect/...`), not the embedded form. You can also send yourself through `/oauth/silent?go=<your start URL>` if the person arrived some other way.
  3. SAIG sees a marked tab with a live session and approves at once: no form, no "Continue as…". It lands on your callback with a code, as usual. With no SAIG session the person signs in once, normally.
  4. `go` must be https on an estate domain (any venture's domain in the manifest, plus skylite.group, saig.page and saigweb.com), otherwise it is refused. The mark lasts 5 minutes and is used once.
  - Don't loop: if your callback fails, show an error page (title contains "failed"/"error") and stop; never re-start sign-on automatically more than once.
- **Land signed in; "Dashboard" instead of "Sign in" (founder ruling 26 Oct 2026, no version bump, nothing for a seat to do on `*.saig.page`).** While a SAIG session exists the console keeps a plain marker cookie `saig_sso=1` for all of `*.saig.page` (no identity, no token; removed on sign-out). Two shared scripts act on it, so every app that loads them behaves the same:
  - `https://console.saig.page/saig-signin.js` (1.4): when `SAIGSignIn.mount(el, url)` or `.open(url)` runs and the marker is present, it goes through `/oauth/silent?go=<url>` instead of showing a form, so the person lands signed in. Once per 90 s per app; if that fails, the form shows. `url` may be your start URL or the SAIG authorize request.
  - `https://console.saig.page/ecosystem-footer.js` (v20): a button, link or clickable element whose text is just "Sign in" / "Log in" (also "Client sign in", "Sign in to X") becomes "Dashboard" while the marker is present. Tune with `data-saig-start="/your/start"` (the button then goes through the silent route to that start URL) or `data-saig-cta="off"` (leave it alone). Apps on other domains see no marker and keep the existing behaviour.
- **Studio-built apps (v18):** the generated helper's `SAIG.data.signIn()` now mounts the same embedded form in the page (a section at the top), not a redirect.
- **Never** the old pop-up window or modal, and never a "Continue with SAIG" button.
- Reference implementations: scorre.app/login, registry.saig.page/register and portfolio.saig.page/edit.

## 2b. Customer sign-in: email + 6-digit code (founder directive, 30 Sep 2026)
Two doors on every app's sign-in page:
- **The business that runs the app signs in with SAIG** (§2): SKYF's practice, Synqro's shop
  owner, MinaOS's agency. "Continue with SAIG".
- **A customer of that business signs in with NO password and NEVER with SAIG:** email address →
  6-digit code sent by email → session. Label it "Client login" / "Customer login".

The pattern that works on the estate's Supabase plan (SKYF shipped it, `skylitefinancial ab8274a`,
live at `/portal/login`; verified end to end: request → SAIG Mail delivery in ~3 s → verify → session):
1. `POST /api/portal/otp { email }` — only addresses already on a customer record get a code; reply
   is identical either way; rate-limit 5 per 10 min per address and per IP.
2. Server: `supabase.auth.admin.generateLink({ type: "magiclink", email })` → `properties.email_otp`
   (6 digits). Project auth config (management API): `mailer_otp_length: 6`,
   `external_email_enabled: true`. **Send the code yourself through SAIG Mail** (`op=send`,
   mailbox = your app's business mailbox, no signature) — the project mailer is capped at 2/hour
   and its template can't be changed on the free plan.
3. Browser: `supabase.auth.verifyOtp({ email, token, type: "email" })` → session; then your
   normal customer mapping by email.
Never expose SAIG SSO to a customer, and never issue a code to an email that is not already a
customer of that business.

---

## 3. Brain link on login (EVERY app does this)
On the SERVER, after SSO, reconcile the user to their canonical `brain_id`:
1. Derive the SAIG subject from the verified session (the OIDC `sub` of the user's
   `custom:saig` identity — in Supabase, the `id` of that identity). Never trust a
   client-supplied value.
2. Call once (idempotent):
   ```
   POST {identity}?op=link
   headers: x-saig-service-token: <SAIG_SERVICE_TOKEN>
   body: { "authUserId": "<SAIG sub>", "app": "<yourApp>", "localUserId": "<your local user id>" }
   -> { "ok": true, "brainId": "...", "kind": "human" | "business" }
   ```
3. Store the returned `brainId` (and `kind`) locally; use `brainId` as your cross-app key.
   Keep your own `user_id` for local access control only.

`brain_id` = whose reality the data belongs to. `user_id` = access control only.

---

## 4. Account type (kind)
SAIG accounts choose **Individual** or **Business** at signup (only on the SAIG signup
page — do NOT add your own selector). The console mints the matching brain kind:
`individual → human`, `business → business`.

`resolve`/`link` return `kind`. Store it and branch:
- `business` → company/org context, business tier, company-level data.
- `human` → individual.
Absent (older accounts) → treat as `human`. Change later via `set_kind`.
Full reference: https://console.saig.page/ecosystem/SAIG_ACCOUNT_TYPES.md

---

## 4a. Founder accounts: always top tier, always see everything (v19, founder rule 8 Oct 2026)
These four SAIG accounts are the founder's: **sheryar@skylite.group, accounts@skylite.group, sheryarmajid@gmail.com, dev@skylite.group**.
In every app they must:
- get the app's **highest paid plan** (Pro or above) with no payment and no trial clock, shown as Pro, never "Free";
- see every admin, founder and estate-only screen.
Implement it as one server-side check: if the signed-in SAIG email is in `FOUNDER_EMAILS` (default: the four above; console env `COUNCIL_ADMINS` carries the same list), resolve the plan to the top tier before any billing lookup. Never hard-code a shorter list; the console's `lib/entitlements.mjs` returns `internal` for them and shows it as "Founder · Pro".
Acceptance: signed in as accounts@skylite.group, the app shows the top plan and every founder-only screen.

## 5. Consent (before any cross-app data)
A brain authorises `{fromApp → toApp : scope}`. Nothing crosses without a grant.
- **Granting (user connects app B in app A):** app A calls (service mode)
  `POST {identity}?op=consent_grant { brainId, fromApp:"A", toApp:"B", scope:"..." }`.
- **Serving (app B before returning data):** app B calls
  `GET {identity}?op=consent_check&brainId=..&fromApp=A&toApp=B&scope=..` → `{ allowed }`.
  If `false` → 403.

Scopes (owned/documented by each app): `finance:read`, `finance:submit`, `accounts:read` (Hisaab),
`qa:score`, `qa:read` (SCORRE), `commerce:read/write` (Synqro), `kyc:verify/read` (KYC),
`knowledge:read`. See the spec for the full taxonomy.
- `accounts:read` (Hisaab) — read a brain's classified trial balance / statutory-accounts data via `/api/ext/trial-balance` (consumed by Skylite Financial); fails closed (403) without the grant.

---

## 6. /api/ext — cross-app data surfaces

**Required (v3): SAIG Health.** Every app exposes `GET /api/ext/health` in two modes,
both gated by `x-saig-service-token`:

- **Shallow (no params)** — liveness, unchanged: `{ ok, app: "<slug>", guideVersion, ts }`.
- **Deep (`?deep=1`)** — the full health battery returning the standard **Snapshot**
  (specVersion 1): env presence booleans (names only, never values), identity-spine
  checks, an honest self-test (uniform check shape `{id,label,status:green|amber|red|skipped,detail?,remedy?}`
  — a check that cannot run reports `skipped` with a remedy, never a false green),
  dependency checks (key-present vs actually-working), and recent errors (≤300 chars,
  no secrets). Full contract, self-test steps, diagnostic-report format and the Console
  Health Hub behaviour: https://console.saig.page/ecosystem/SAIG_SYSTEM_HEALTH_SPEC.md

The Console Health Hub (console.saig.page/diagnostics) fans out to every app's
health URL (now listed per venture in the manifest), stores org-wide snapshots, and
shows liveness-only apps as amber until they implement `?deep=1`. Local admin health
pages (Pulse `/app/debug` is the reference) remain the app-level view.
If your app **exposes** data to the ecosystem, expose it under `/api/ext/*` per the
contract: service-token verifier, `X-SAIG-App` (caller) + `X-SAIG-Brain` headers,
`consent_check` before serving, idempotency on `X-SAIG-Event-Id` for writes, and a signed
completion event on writes. If your app **consumes** another's data, call its `/api/ext/*`
server-side with your service token + `X-SAIG-App` + the canonical `brainId`.
Full contract (envelopes, error codes, per-venture surfaces):
https://console.saig.page/ecosystem/SAIG_EXT_API_CONSENT_AND_TOOL_REGISTRY_SPEC.md

## 6c. Colleague protocol: every app is a colleague, wired in from birth (v20, founder directive 9 Oct 2026)
Every SAIG app is a **colleague**: an agent that SAIG AI (and every other app) can ask, and that can act, with the person's
consent. An app is wired when it publishes ONE self-describing card. Nothing is hand-written per app anywhere else: SAIG AI,
the Council, Studio and outside AI tools read the card. **The live card wins** over any document (#156 lesson).

**1. Publish the colleague card at `GET /api/ext`** (public, no token; describes, never returns data):
```json
{
  "protocol": "saig-colleague/1",
  "app": "skyf", "name": "SKYF", "version": "2026-10-09",
  "role": "Accountant: incorporates companies, keeps books, prepares and files accounts and tax returns",
  "ask": "What SKYF can answer, in one line (used when SAIG AI decides whom to ask)",
  "personal": true,
  "scopes": [{ "scope": "accounts:read", "description": "Read your companies' filings and deadlines" }],
  "tools": [{
    "name": "deadlines",                       // unique in this app; SAIG AI calls it "skyf.deadlines"
    "description": "Upcoming Companies House and HMRC deadlines for the person's companies",
    "method": "GET", "path": "/api/ext/deadlines",
    "scope": "accounts:read",                   // omit for estate-level (non-personal) tools
    "write": false,                             // true = changes something
    "confirm": false,                           // true = SAIG AI must show an approval card first (required for money, sending, filing, deleting)
    "input": { "type": "object", "properties": { "company": { "type": "string" } } }   // JSON Schema (MCP inputSchema)
  }],
  "events": ["accounts.filed"], "health": "/api/ext/health", "docs": "https://…"
}
```
`tools[]` is MCP-compatible (`name`, `description`, `inputSchema` = `input`), so the same card serves SAIG AI, the console
and any MCP client.

**2. Serve each tool** exactly as §6 says: per-app token in `x-saig-service-token` (verify with `lib/saig-auth.mjs`, or ask
SAIG Identity `op=app_token_check` if your app does not hold the pepper), `X-SAIG-App` = caller, `X-SAIG-Brain` for personal
data, `consent_check` before serving (fail closed, 403 `consent_denied`), `X-SAIG-Event-Id` idempotency on writes,
envelope `{ ok, data }` / `{ ok:false, error }`. GET tools take query parameters; POST tools take the JSON body.

**3. Registration is automatic.** The console reads every Registry seat's card nightly on saig-runner and on demand; SAIG AI
lists the colleague under **Connectors** (personal scopes) and gives its tools to the agent. A new Studio app is born with a
card (Studio template), so it is a colleague the moment it deploys.

**4. Governance.**
- Sentinel checks the card (valid JSON, every tool path answers, writes have `confirm` where they move money, send, file
  or delete) and lists gaps in your `.saig/SENTINEL.md`.
- A new **write** tool, or a new scope, is announced on the Council (type: `announce`, "new colleague tool") before it ships.
- The person's consent is per app and per scope; founder accounts follow §4a.
- Every write a colleague makes for SAIG AI is recorded (who asked, which tool, which brain) by the caller.

**Acceptance:** `GET https://<your-app>/api/ext` returns the card; SAIG AI (ai.saig.page → + → Connectors) lists you;
asking SAIG AI one of your read tools' questions returns your data with "Looked at: <app>.<tool>".

---

## 6d. Sentinel browser: every seat has a real browser, and a test account (v21, founder directive 10 Oct 2026)

Every seat can open a real Chromium browser on SAIG Desk, through Sentinel, to **see its site live**, **test it signed in**,
or **do desk research on the open web**. Four live browsers run side by side (plus headless checks), shared as a pool:
ask when you need one, end it when you're done. Each seat sees only its own sessions.

**Your test account:** `test-<your-app-id>@skylite.group` already exists in SAIG Identity (all 66 Registry seats, 10 Oct).
The engine holds the password; you never see it. Make sure that account can use your app (workspace, plan, sample data),
because a signed-in check signs in as it through SAIG sign-on.

**API** (your per-app token in `x-saig-service-token`, `X-SAIG-App: <your id>`), `https://console.saig.page/api/sentinel`:

| Call | What it does |
|---|---|
| `POST ?op=browser { url, mode: "live" }` | Opens the page in a live browser. Returns `viewUrl`: send it to the person; it opens the browser as soon as one is free. Add `signin: true` to sign in as your test account first. |
| `POST ?op=browser { url, mode: "check", signin?: true }` | Headless: opens the page (signed in if asked) and takes a screenshot. Poll status for `screenshots`, `log` and `diagnostics` (console errors, failed requests, 4xx/5xx). |
| `POST ?op=browser { url, mode: "research" }` | A live browser on the open web for desk research. Read-only: it opens and reads pages; nothing is filled in or submitted. |
| `GET ?op=browser_status&id=` | `state` (queued, running, handoff = live and yours to steer, done, failed), `log`, `screenshots`, `viewUrl`. |
| `POST ?op=browser_go { id, to }` | Steer a live browser: a URL, `back` or `reload`. |
| `POST ?op=browser_end { id }` | End it and free the browser for the next seat. Always end what you open. |
| `POST ?op=test_account { rotate?: true }` | (Re)creates your test account; the engine keeps the new password. |

Custom step lists still go to the engine directly (`/api/browser?op=session`, step kinds in that file). Limits: 2 live
browsers per seat at a time; sessions that sit queued 20 minutes, go silent for 30, or wait 24 hours for approval expire on
their own. The browser never presses submit, pay, file or send (M-015): a person does that in the live view.

### 6d.1 Sentinel error reporting (v24, #1652)
Browser errors already arrive from `ecosystem-footer.js`. For **server** errors, post the same shape yourself:
`POST https://console.saig.page/api/sentinel?op=error` with `x-saig-service-token: <your SAIG_APP_TOKEN>`, `X-SAIG-App: <your id>` and body `{ "message": "...", "stack": "...", "url": "https://your.app/path", "level": "error" }` → `202 { ok, fingerprint }`. Errors are grouped by fingerprint with a count; emails, tokens and query strings are stripped; 30 per 5 minutes per app. Read yours back with `GET ?op=errors&app=<id>` (shared token) or in your Sentinel inbox. Call it from your catch blocks and cron handlers, never block the response on it.

## 6b. New engines and apps (August 2026)

Three ventures joined in the week of 16–18 August. **Two of them are engines you can consume.**

| Venture | What it is | Consume it via |
|---|---|---|
| **Tapline** `tapline.saig.page` | **An engine.** A printed QR/NFC code becomes a direct line to a human — two-way video in the browser, no hardware, no phone numbers, no app for whoever scans. | `POST /api/tapline?op=issue { ownerBrain, kind, label, behaviour, appKey, count }` → codes, URLs, QR images. Behaviours: `call` · `lost_found` · `message` · `info` · `checkin` (deep-links back into YOUR flow). Health: `/api/ext/health`. |
| **BitPak** `bitpak.saig.page` | Client crypto portfolios and a PKR-first exchange for Pakistan. Entity **Skylite Consulting (Pvt) Ltd**, NOT Skylite Group Ltd. | Not yet a general engine. **⚠️ No PVARA licence or NOC is held — no surface may render BitPak as "licensed".** SAIG Pay's Crypto tab must stay invisible to anyone who is not already a BitPak client. |
| **Worth** `worth.saig.page` | Consent-first personal data: see what companies hold on you, decide, and get paid if you choose to sell. | Engine (**SAIG Consent**) is spec, not built. Waitlist API live. |

**Tapline is the one to look at.** If your app has a physical touchpoint — a door, a room, a
vehicle, an asset, a keyring — you can issue tags against your own `appKey` and store no tag state
yourself. @samaconcierge: a short-stay guest arriving at a property with no doorbell scans and
video-calls the host, with no numbers exchanged.

---

## 7. Environment variables
Every app:
```
SAIG_IDENTITY_URL  = https://console.saig.page
SAIG_SERVICE_TOKEN = <shared value, identical across the console + all apps>   # server-side only
```
Finance consumers (e.g. LifeHQ) additionally:
```
HISAAB_API_URL       = <Hisaab base>
HISAAB_SERVICE_TOKEN = <Hisaab's inbound /api/ext token>
# ⚠️ NEVER code a fallback of HISAAB_SERVICE_TOKEN || SAIG_SERVICE_TOKEN — Hisaab REJECTS the
# shared estate token (401). Silent fallback + best-effort emit = invisible data loss (#156).
```
`SAIG_SERVICE_TOKEN` must be byte-identical everywhere or calls 401.

---

## 7b. Database: every new table in `public` needs explicit GRANTs (from 30 Oct 2026)

Supabase stops auto-granting Data API access to **new** tables in the `public` schema on
**30 October 2026**, on every project (existing projects included). Existing tables keep their grants;
nothing breaks today. From that date a table created without grants is unreachable through
supabase-js / PostgREST — including through the **service role** — and the call fails with
`permission denied`.

**Rule (effective now, so migrations written today still work after 30 Oct):** the migration that
creates a table in `public` also grants on it, only to the roles that need it. Keep RLS on.

```sql
create table public.example (...);
alter table public.example enable row level security;
-- server-only table (the usual case in this estate):
grant select, insert, update, delete on public.example to service_role;
-- add ONLY if the browser reads it under RLS:
-- grant select, insert, update, delete on public.example to authenticated;
-- grant select on public.example to anon;
```

This also applies to preview branches and a local `supabase db reset`. Do **not** restore the old
behaviour with `alter default privileges … to anon, authenticated` — least privilege is the point.

## 7c. Scheduled jobs run on saig-runner, never on GitHub (founder directive 1 Oct 2026)
GitHub Actions minutes are off for the whole estate, and GitHub's `on: schedule` is unreliable (MinaOS saw */15 jobs never fire). **Never use `on: schedule`, pg_cron inside your app, or Vercel cron for estate jobs.** Every recurring job runs on **saig-runner's own scheduler** (systemd timers):
- **HTTP jobs:** an idempotent authenticated `POST` to your app (your `SAIG_APP_TOKEN` in `x-saig-service-token`). Ask the console on the Council with a table: job name, schedule (UTC or Europe/London), URL. Live within a day, read back on the thread.
- **Code jobs** (scripts that need a checkout): the seat-job runner runs `<command>` in a fresh checkout of your repo with your seat env. Same ask, plus the env names you need.
- Jobs are `Persistent` (a missed run catches up after a reboot) and their results are in the runner journal; ask for a read-back any time.

## 8b. Email: everything goes through SAIG Mail (founder directive, 24 Sep 2026)

SAIG Mail (`saigmail`) is the **only** email system in the estate: sending (transactional and
person-to-person), receiving, mailboxes, signatures, drafts, search, inbound webhooks and the
**authentication emails** (sign-in links, password resets, invites). This covers every existing app,
every new app, and everything SAIG Studio generates.

- **Do not** call Resend, SendGrid, Postmark, Mailgun, Amazon SES or any SMTP server from an app. Do
  not add new keys for them. Existing ones are removed per app once its SAIG Mail path is proven.
- **Send / read / sign** through SAIG Mail's API (`https://saigmail.saig.page/api/…`, contract on
  Council #998): estate service token + `X-SAIG-App: <your id>`.
- **Auth emails:** every Supabase project's SMTP points at SAIG Mail's SMTP relay. No Supabase
  built-in mailer, no project-level SES.
- **Inbound:** replies and inbound mail reach apps by SAIG Mail's signed webhook
  (`x-saig-timestamp`, `x-saig-signature: sha256=HMAC(token, ts + "." + rawBody)`), never by an app
  logging into a mailbox itself.
- Console's `/api/mail/send` and `/api/postmaster` are **being retired**: during the move they forward
  to SAIG Mail, then return `410 moved_to_saigmail`.

## 8. Shared ecosystem footer
Mount the shared band (auto-updates across the ecosystem):
```html
<div class="saig-ecosystem-footer" data-venture="YourApp" data-accent="#yourhex"></div>
<script src="https://console.saig.page/ecosystem-footer.js" defer></script>
```
`data-venture` marks your node "you are here"; `data-accent` blends the orb/hovers to your
brand. Omit `data-venture` on the hub.

---


**The uniform SAIG header and apps grid (v7, 25 Sep 2026).** The footer script now also renders a thin
**SAIG header** at the very top of every app: the SAIG mark and your app's name on the left, the Google-style
**SAIG apps** grid on the right (every app, grouped: SAIG tools · Finance & business · Travel · Property ·
Life & communication · Group & governance). It is **automatic** for any app that loads the footer script.
Choose where it sits, or integrate the grid into your own header instead:

```html
<div class="saig-ecosystem-header" data-venture="YourApp"></div>   <!-- the bar renders here -->
<span data-saig-launcher></span>   <!-- OR: just the grid button inside your own header (no bar) -->
<meta name="saig-header" content="off">   <!-- opt out only with the founder's agreement -->
```

If your header is `position: fixed` at the top, use one of the two mounts above so the bar is not hidden under it.

**Account avatar in the header (v17, founder rule 8 Oct 2026).** Top right, beside the apps grid, the header shows who is signed in to *your* app, with **Switch account** and **Sign out**. The header is shared but the account is yours, so tell it: add `<meta name="saig-account" content="/api/me">` (an endpoint returning `{ signedIn, email, name, photo }`), or call `SaigEcosystemFooter.setUser({ email, name, photo, signOut, switchAccount })` after sign-in (`setUser(null)` after sign-out). Defaults: sign out `/api/auth?op=logout&next=/`, switch `/api/auth?op=logout&switch=1&next=<page>`. Apps that already draw their own avatar in their own header (using `data-saig-launcher`) keep theirs.

**One account menu everywhere (v18, founder rule 8 Oct 2026).** Clicking the avatar opens the same menu in every app: the person's name and email, **SAIG account settings**, **Change picture**, **Switch account**, **Sign out**. Change picture lets people pick a preset avatar or upload their own photo; it is one picture per SAIG account, stored by the console (`/api/saig/identity?op=avatar`, `avatar_set`, `avatar_clear`) and shown in every app's header (the shared header reads it through a hidden `console.saig.page/avatar-bridge` frame). Do not draw a different menu: apps with their own header call `SaigEcosystemFooter.setUser(...)` or copy these five items exactly (label wording included), and use `/api/saig/identity?op=avatar` for the picture.

**SAIG account settings inside the app (v32, founder ruling 23 Oct 2026 22:00, #1941).** The account menu never links out. Tapping **SAIG account settings** or **Change picture** opens an **in-app sheet** that frames the console's page — `https://console.saig.page/account/settings?embed=1&app=<seat>` (name, picture, passkeys: list, add on this device, remove; sign-in methods; a Done button) and `https://console.saig.page/account/avatar?embed=1&app=<seat>` — on top of the app's own page. The person never leaves the app. Rules:
1. The shared header (ecosystem-footer.js v19) does this with no app code. An app with its own header frames the same two pages in its own sheet: `<iframe src="https://console.saig.page/account/settings?embed=1&app=<seat>" allow="publickey-credentials-create *; publickey-credentials-get *">`. The `allow` attribute is required, or passkeys cannot be created in the sheet.
2. Listen for the console's messages (`event.origin === "https://console.saig.page"`): `{saigAccountChanged: {name, image}}` → repaint your avatar and name; `{saigAccountClose: true}` → close the sheet. Programmatic open: `SaigEcosystemFooter.openAccountSettings()`.
3. Passkeys are created in the frame on Chrome/Edge/Android. Where a browser refuses WebAuthn inside a frame (older Safari), the page itself offers "Add it in a small window": a popup of the same page that reports back and closes itself — never a full navigation. Do not build your own fallback.
4. The five menu items and their wording stay exactly as in v18; only where they open changes: in the sheet, in the app. Password and two-step verification stay on `console.saig.page/settings` (opened in a new tab from inside the sheet).
5. Governance check for every seat: the account menu has no `href` to `console.saig.page/settings`. Read back by opening the menu in your Sentinel browser and tapping SAIG account settings: the sheet must appear on your own page.

Want the old icon band instead of the slim footer? `data-style="full"` on the footer mount.

## 10. Staying in sync (set up once, then it's automatic)
This guide is **versioned** — the current version is in the manifest at
`integration_guide.version`. When it changes, re-read, apply the deltas, then bump the
version your app records as implemented.

**Changelog:** v36 (2026-11-03) — §0n The own stack: SAIG Vault, SAIG Data, SAIG Cloud; names, no GitHub workflows/secrets, Schema-only migrations, no Vercel-only features, the move is done by the console; `OWN_STACK.md` is the record. · v35 (2026-10-29) — §0m AI-first: one key, one card, one connector; every seat's connector served by the console at `/mcp/<seat>` from its colleague card; cards must be true for a named person; seats own their connector's quality from the console's probe onward (CON-R-090..095). v34 (2026-10-24) — §0l payments never leave the app: `op=embedded-payment`, embedded `membership-session`, in-app card update; hosted redirect only by explicit opt-in; every seat lists and switches its Stripe redirects (#2047). Clarification: connector `web_search` / `web_fetch`. v33 (2026-10-24) — §0k SKYE, the command centre: the console chat is the founder's front door and orchestrator; colleagues stay separate; one record (journal rule, catch-up line, estate ledger); perfect-handover standard for `compact`; SKYE in SAIG Meet. v32 (2026-10-23) — §8 SAIG account settings inside every app (#1941): the account menu opens `console.saig.page/account/settings?embed=1&app=<seat>` (name, picture, passkeys list/add/remove, sign-in methods, Done) in an in-app sheet with `allow="publickey-credentials-create *; publickey-credentials-get *"`, never a link out; `saigAccountChanged` / `saigAccountClose` messages; footer v19 does it for the shared header; popup fallback for browsers that refuse WebAuthn in a frame. (23 Oct, clarification, no version change: this guide, the manifest, seats.json and the footer now write every address as its saig.page name, and the console calls every engine on saig.page; parity probe 23 Oct: every estate API answers the same on both names. Your own code is the remaining work: §0h dates stand — people-facing links by 30 Oct, everything else by 12 Nov.) (23 Oct, clarification, no version change: §0c.1 runner_jobs/runner_run in the connector; SAIG Vault live at vault.saig.page with hourly mirrors.) v31 (2026-10-23) — §0c.1 Council v3: the Council database is the record and GitHub only a mirror; SAIG Council connector (MCP at https://console.saig.page/mcp, SAIG sign-in) gives chats direct read/post/close; SAIG AI triage of who owes each thread; duplicate threads merged; routine notices go to a daily digest, not threads; one subject = one thread with several recipients. v30 (2026-10-22) — §0j SAIG AI is the one front door for every AI job (text, vision, search, images, voice, embeddings, video); `GET /api/ai?op=models` directory is the catalogue; template video free via HyperFrames (`op=video_templates` / `video` / `video_status`), generative video and premium images (Higgsfield) released per app (Mirage only); free search fallback SAIG Search; directories updated in the same change; governance greps for provider calls/keys. (22 Oct, clarification, no version change: §0i customer-supplied keys/BYOK allowed under conditions.) v29 (2026-10-22) — §0h estate APIs and webhooks: canonical host saig.page (same paths), new code and browser calls now, server-to-server and webhook registrations by 12 Nov, skylite.group API hosts keep answering (never 308, 30 days notice before retirement), verify webhooks by signature not host. §0i own infrastructure first → paid providers through estate engines → connectors/Claude chat tools last; no production flow on a connector; Zapier audit by every seat by 29 Oct. v28 (2026-10-22) — §0g the estate moves to saig.page: `<label>.saig.page` for every app and engine, `manifest.hosts`, skylite.group names keep serving then 308 pages (never API paths); only the homepage stays. v27 (2026-10-15) — §0f seats propose their own skills with `propose_skills` (founder taps Save); the console is only the fallback when a chat lacks the tool. v26 (2026-10-15) — §2a silent SAIG sign-on for connect/consent steps across domains (`/oauth/silent?go=`; #1719). v25 (2026-10-14) — §0f skills: every seat assesses and builds skills for its routines (repo + founder account, kept identical), START_HERE/AGENTS/CLAUDE pointers in every repo, Studio apps ship with skills and monitoring wired from day one. v24 (2026-10-11) — §1.3 per-app token versions and rotation (refuse old versions, never log a token, what every app already has with its token). v23 (2026-10-11) — three standing rules at the top (chat map, Council API + always close threads, copy-paste nudge); §0c.1 close rules + Council janitor. v22 (2026-10-11) — §0e chat map (seats.json `chats` + per-seat `chat`) and the copy-paste nudge: end every message that needs another chat with a one-line code block. v21 (2026-10-10) — §6d Sentinel browser. v20 (2026-10-09) — §6c colleague protocol (GET /api/ext card, MCP-compatible tools, automatic registration, governance). v15 (2026-10-03) — §0c.7 GitHub (User account) + Vercel (team id, commit author) facts; §0c compact, workboard-first council (op=board), efficiency rules. v14 (2026-10-03) — §0c code words build, governance, sentinel; SAIG Blueprint (.saig/BLUEPRINT.md until the API). v13 (2026-10-03) — §0c founder code word "council": full Council sweep from one inbox call. v12 (2026-10-02) — §E engine catalogue (manifest `engines`). v11 (2026-10-01) — §7c: scheduled jobs run on saig-runner, never GitHub `schedule:`. v10 (2026-10-01) — §0b: ethos and safeguards (manifest `ethos`); §0a: also read your Sentinel inbox. v9 (2026-10-01) — §0a: read the announcements (manifest `announcements` + `renames`) at the start of every session and acknowledge each; §10b check warns when any are waiting. v8 (2026-09-30) — §2b: customer sign-in by email + 6-digit code (businesses use SAIG; customers never do). v7 (2026-09-25) — §8: uniform SAIG header (automatic) with the apps grid. v6 (2026-09-25) — §8: slim footer + SAIG apps grid; header slot `data-saig-launcher` required. v5 (2026-09-24) — §8b: all email (send, receive, mailboxes, auth emails) through SAIG Mail only. v4 (2026-09-23) — §7b: explicit GRANTs in the same migration for every new `public` table (Supabase change effective 30 Oct 2026). v3 (2026-07-10) — SAIG Health deep battery required (§6, spec link above). v2 — identity/consent/ext conventions. (22 Sep 2026: §10 snippets repaired — they had been published with a non-JavaScript placeholder in place of `IMPLEMENTED`; no version change.)

**(a) Record the version you implement.** Keep a constant + repo note, e.g.
`SAIG_GUIDE_VERSION = 2`. Bump only when you've re-synced to a newer guide.

**(b) Deploy-time check (recommended).** Warn when the central guide is ahead of what
you've implemented. Add `scripts/saig-guide-check.mjs`:
```js
const IMPLEMENTED = 3; // the guide version THIS app implements — keep equal to SAIG_GUIDE_VERSION
const r = await fetch("https://console.saig.page/ecosystem/manifest.json").catch(() => null);
const j = r && r.ok ? await r.json() : null;
const latest = j?.integration_guide?.version;
if (latest && latest > IMPLEMENTED) {
  console.warn(`\n⚠  SAIG integration guide is v${latest}; this app implements v${IMPLEMENTED}.`);
  console.warn(`   Re-read ${j.integration_guide.url} and bump IMPLEMENTED.\n`);
  // To hard-block deploys until re-synced: process.exit(1);
}
// v9: announcements waiting? (see §0a)
import fs from "node:fs";
let seen = 0; try { seen = JSON.parse(fs.readFileSync(".saig/announcements.json", "utf8")).last_seq || 0; } catch {}
const waiting = (j?.announcements?.items || []).filter((a) => a.seq > seen);
if (waiting.length) {
  console.warn(`\n📣 ${waiting.length} SAIG announcement(s) not yet acted on:`);
  for (const a of waiting) console.warn(`   #${a.issue} ${a.title} → ${a.action}${a.deadline ? " (by " + a.deadline + ")" : ""}`);
  console.warn(`   Act, ack on each thread, then set last_seq in .saig/announcements.json.\n`);
}
```
Wire it into `prebuild`/`prepush`, e.g. `"prebuild": "node scripts/saig-guide-check.mjs"`.

**(c) Runtime freshness banner (optional, drop-in).** The shared footer publishes the
current guide version on `window.__saigEcoFooter.ecosystem`. Paste once:
```html
<script>
(function () {
  var IMPLEMENTED = 3; // the guide version THIS app conforms to — keep equal to SAIG_GUIDE_VERSION
  function show(eco) {
    if (!eco || !eco.guideVersion || eco.guideVersion <= IMPLEMENTED) return;
    console.warn("SAIG integration guide v" + eco.guideVersion + " > implemented v" + IMPLEMENTED + " — " + eco.guide);
    var devOnly = /^(localhost|127\.0\.0\.1)$/.test(location.hostname) || localStorage.getItem("saig_show_guide_banner") === "1";
    if (!devOnly) return; // never shown to normal end-users
    var b = document.createElement("div");
    b.textContent = "SAIG integration guide updated to v" + eco.guideVersion + " — review " + eco.guide;
    b.style.cssText = "position:fixed;bottom:0;left:0;right:0;z-index:99999;background:#7c5cff;color:#fff;font:600 12px/1.4 system-ui;padding:8px 14px;text-align:center";
    document.body.appendChild(b);
  }
  var n = 0, t = setInterval(function () {
    var eco = (window.__saigEcoFooter || {}).ecosystem;
    if (eco) { show(eco); clearInterval(t); } else if (++n > 20) clearInterval(t);
  }, 500);
})();
</script>
```
