# Declared presence — provisioning the Telegram surface

`FT-WP-0001` T01–T03 were written as human steps: register a bot through
BotFather, create two channels, generate a salt. This document replaces that
route with a declared specification and a reconciler, and states honestly which
part of it cannot be automated and why.

## The constraint that shapes everything

**The Bot API cannot create a bot or a channel.** It can only act as one. Both
acts are client capabilities, reachable only through MTProto with a *user*
account — Canon INT-03, "capabilities unavailable through the Bot API".

So the provisioner is an MTProto client acting as a designated operator account.
It messages BotFather the way a person would, and it calls `channels.createChannel`
the way a client would.

Three things genuinely cannot be derived from a specification:

| Human step | Why | Frequency |
|---|---|---|
| A Telegram account for the operator | Requires a phone number and a device | Once |
| `api_id` / `api_hash` | Issued by a web form at my.telegram.org | Once |
| The login code (and 2FA password) that mints the MTProto session | Telegram sends it out of band, by design | Once, and again if the session is revoked |

Everything else — bot registration, naming, description, avatar, channel
creation, visibility, administrator rights, the redaction salt — is declared and
reconciled.

That is the honest boundary. This is not "no human steps"; it is **one bounded
bootstrap, then a declared surface that converges.** The steps that remain are
the ones Telegram places outside any API on purpose.

## Where the specification lives

The presence spec is **editorial**, not mechanical. It carries the bot's name,
its description, its avatar, and the channel titles a stranger will read. That is
brand, and brand belongs to the campaign:

```
pr-hall-of-helix/presence/telegram.yaml     # the declared presence  (campaign owns)
fluid-telegram/presence/telegram.schema.yaml # the schema it validates against
fluid-telegram/presence/resolved/<campaign>.yaml  # what provisioning produced
```

The provisioner takes a spec path as its input, so this interface stays reusable
by any HelixForge campaign rather than being about the Hall of Helix. It follows
the split `FT-WP-0001` T13 already draws: what to say belongs to the campaign;
how it is carried and proven belongs here.

## The two planes

```
  provisioning plane                    request path
  ------------------                    ------------
  operator (human) triggers             pr-hall-of-helix
      |                                     |
      v                                     v  POST /v1/channel-posts
  provision plan  ──▶ human reads ──▶ apply  fluid-core ──▶ adapter ──▶ Bot API
      |                                                        (post_messages only)
      v
  MTProto as operator account
  BotFather · channels.createChannel · channels.editAdmin
```

They share nothing but OpenBao and the resolved-state file. **The adapter has no
provisioning code path and no MTProto session.** It holds a bot token with
`post_messages` and nothing else, so a compromised adapter cannot create,
rename, delete or re-permission anything.

This is what keeps the scheme inside `InterfaceEvolutionIntent.md` §7, which
forbids the Daimon from creating channels or bots or changing permissions. The
provisioner is not the Daimon: it is operator-triggered, it is outside the
request path, and every run is a plan a person approved. §7's prohibition is on
*autonomous* administration, and nothing here is autonomous.

## plan / apply

Terraform's shape, deliberately, because the semantics are already understood.

- **`plan`** reads the spec, reads live Telegram state through MTProto, reads the
  resolved-state file, and prints a diff. It writes nothing.
- **`apply`** executes a plan the operator approved. It is idempotent: a second
  apply over an unchanged spec is a no-op, and every action is keyed on a
  resolved id rather than on a name.

Reconciliation is **converging, never destructive**:

- The provisioner has **no destroy path.** Deleting a channel destroys its
  subscribers and its post history irreversibly, and no specification is worth
  trusting with that. Removing a channel from the spec produces a warning, not a
  deletion.
- **Drift on a destructive field reports and stops.** If a channel's username has
  been taken over, or the bot has been demoted, `apply` says so and exits
  non-zero. It does not "fix" its way through a situation it does not understand.
- **Administrator rights are clamped, not declared.** The provisioner grants
  `post_messages` and refuses to grant anything else *even if the spec asks for
  it*. A spec requesting `can_delete_messages` fails validation. The intent
  forbids the system from holding a right it is not allowed to exercise, so the
  safe place to enforce that is where the right is granted.
- **The private test channel is created before the public one**, and `apply`
  refuses to touch the public channel until the private one has recorded a
  successful test publication. Canon PUB-01, and `FT-WP-0001` T02.

## Secrets

Nothing sensitive enters the spec or the resolved state. Both are committed.

| Secret | Path | Rule |
|---|---|---|
| MTProto session string | `bao:.../telegram/operator-session` | Provisioning only. Never given to the adapter. |
| `api_id` / `api_hash` | `bao:.../telegram/operator-app` | Provisioning only. |
| Bot token | `bao:.../telegram/bot-token` | Written by `apply` the moment BotFather issues it, read by the adapter at start. Never logged, never echoed, not even in error text. |
| Redaction salt | `bao:.../telegram/redaction-salt` | **Create-if-absent, never overwrite.** |

The salt rule is a hard one. `docs/observation.md` explains why: rotating it
silently invalidates every longitudinal comparison the interface has ever made,
and it does so without any visible failure. So the provisioner generates it once
if it is missing and will not replace it — the only way to change it is a
deliberate human write to OpenBao, which is a decision, not a run.

## What provisioning produces

`presence/resolved/<campaign>.yaml`, committed, no secrets:

```yaml
resolved:
  campaign: hall-of-helix
  spec_digest: "sha256:..."      # the spec this state came from
  provisioned_at: "..."
  bot:
    username: "..."
    id: 123456789
  channels:
    test:   { chat_id: -100..., username: null,  admin_rights: [post_messages] }
    public: { chat_id: -100..., username: "...", admin_rights: [post_messages] }
```

This is what the adapter's configuration is derived from, and what `plan` diffs
against. `spec_digest` is the link that makes drift detectable: if the spec
changed and the digest did not, provisioning is behind.

## Rate and account safety

Automating a user account is not what Telegram's terms are written around. Three
mitigations, all cheap:

- Use a **dedicated operator account**, never a person's own. If it is limited,
  nothing personal is lost.
- The provisioner runs at **human pace** — it is a reconciler that runs on
  change, not a loop. BotFather conversations are rate-limited to one exchange at
  a time with real delays between messages.
- The session **publishes nothing.** All ordinary traffic goes through the bot
  token on the Bot API, which is the supported surface. The user session exists
  only to do the three things the Bot API cannot.

## Open question for the operator

`InterfaceEvolutionIntent.md` §7 lists channel and bot creation under "explicit
non-authority" without distinguishing the Daimon from an operator-run tool. The
reading above — that §7 constrains autonomous action, and an approved plan is not
autonomous — is the intended one, but it is currently a reading rather than
something the document says. A one-sentence clarification in §7 would settle it.
That is a governance edit to a constitutional document, so it is proposed here
rather than made.
