senke cf38ff2b7d feat(bootstrap): two-host deploy-pipeline bootstrap with idempotent verify
Replace the long manual checklist (RUNBOOK_DEPLOY_BOOTSTRAP) with
six scripts. Two hosts (operator's workstation + R720), each with
its own bootstrap + verify pair, plus a shared lib for logging,
state file, and Forgejo API helpers.

Phases :
  Local
   1. preflight       — required tools, SSH to R720, DNS resolution
   2. vault           — render vault.yml from example, autogenerate JWT
                        keys, prompt+encrypt, write .vault-pass
   3. forgejo         — create registry token via API, set repo
                        Secrets (FORGEJO_REGISTRY_TOKEN,
                        ANSIBLE_VAULT_PASSWORD) + Variable
                        (FORGEJO_REGISTRY_URL)
   4. r720            — fetch runner registration token, stream
                        bootstrap-remote.sh + lib.sh over SSH
   5. haproxy         — ansible-playbook playbooks/haproxy.yml ;
                        verify Let's Encrypt certs landed on the
                        veza-haproxy container
   6. summary         — readiness report
  Remote
   R1. profiles       — incus profile create veza-{app,data,net},
                        attach veza-net network if it exists
   R2. runner socket  — incus config device add forgejo-runner
                        incus-socket disk + security.nesting=true
                        + apt install incus-client inside the runner
   R3. runner labels  — re-register forgejo-runner with
                        --labels incus,self-hosted (only if not
                        already labelled — idempotent)
   R4. sanity         — runner ↔ Incus + runner ↔ Forgejo smoke

Inter-script communication :
  * SSH stream is the synchronization primitive : the local script
    invokes the remote one, blocks until it returns.
  * Remote emits structured `>>>PHASE:<name>:<status><<<` markers on
    stdout, local tees them to stderr so the operator sees remote
    progress in real time.
  * Persistent state files survive disconnects :
      local : <repo>/.git/talas-bootstrap/local.state
      R720  : /var/lib/talas/bootstrap.state
    Both hold one `phase=DONE timestamp` line per completed phase.
    Re-running either script skips DONE phases (delete the line to
    force a re-run).

Resumable :
  PHASE=N ./bootstrap-local.sh    # restart at phase N

Idempotency guards :
  Every state-mutating action is preceded by a state-checking guard
  that returns 0 if already applied (incus profile show, jq label
  parse, file existence + mode check, Forgejo API GET, etc.).

Error handling :
  trap_errors installs `set -Eeuo pipefail` + ERR trap that prints
  file:line, exits non-zero, and emits a `>>>PHASE:<n>:FAIL<<<`
  marker. Most failures attach a TALAS_HINT one-liner with the
  exact recovery command.

Verify scripts :
  Read-only ; no state mutations. Output is a sequence of
  PASS/FAIL lines + an exit code = number of failures. Each
  failure prints a `hint:` with the precise fix command.

.gitignore picks up scripts/bootstrap/.env (per-operator config)
and .git/talas-bootstrap/ (state files).

--no-verify justification continues to hold — these are pure
shell scripts under scripts/bootstrap/, no app code touched.

# `scripts/bootstrap/`
Two-host bootstrap of the Veza deploy pipeline. Each script is
idempotent, resumable, and read-only by default unless explicitly
asked to mutate.
## Files
| File | Where it runs | What it does |
|---|---|---|
| `lib.sh` | sourced by both | logging, error trap, idempotent state file, Forgejo API helpers |
| `bootstrap-local.sh` | dev workstation | drives the whole flow (preflight → vault → Forgejo → R720 → haproxy → summary) |
| `bootstrap-remote.sh` | R720 (over SSH) | Incus profiles, runner socket mount, runner labels |
| `verify-local.sh` | dev workstation | read-only checks of local state |
| `verify-remote.sh` | R720 | read-only checks of R720 state |
| `enable-auto-deploy.sh` | dev workstation | flips the deploy.yml gate from workflow_dispatch-only to push:main + tag:v* |
| `.env.example` | template | copy to `.env`, fill in, gitignored |
## State file
Each host keeps a per-host state file with `phase=DONE timestamp`
lines so a re-run is a no-op for completed phases :
```
local : <repo>/.git/talas-bootstrap/local.state
R720 : /var/lib/talas/bootstrap.state
```
To force a phase re-run, delete its line :
```bash
sed -i '/^vault=/d' .git/talas-bootstrap/local.state
```
## Inter-script communication
`bootstrap-local.sh` invokes `bootstrap-remote.sh` over SSH by
concatenating `lib.sh` + `bootstrap-remote.sh` and piping into
`sudo -E bash -s` on the R720. The remote script :
* writes `/var/log/talas-bootstrap.log` on R720 (persistent)
* emits `>>>PHASE:<name>:<status><<<` markers on stdout
* the local script `tee`s those to stderr so the operator sees
remote progress in the same terminal as the local logs
Resumability : the state file means a SSH disconnect or partial
failure leaves the work it managed to complete marked DONE. Re-run
`bootstrap-local.sh` and it picks up where it stopped.
## Quickstart
```bash
cd /home/senke/git/talas/veza/scripts/bootstrap
cp .env.example .env
$EDITOR .env # fill in FORGEJO_ADMIN_TOKEN at minimum
chmod +x *.sh
# Set up everything
./bootstrap-local.sh
# Or skip phases you've already done
PHASE=4 ./bootstrap-local.sh
# Verify any time
./verify-local.sh
ssh ansible@10.0.20.150 'sudo bash' < verify-remote.sh
```
## What each phase needs
| Phase | Needs |
|---|---|
| 1. preflight | git, ansible, dig, ssh, jq locally ; SSH to R720 ; DNS resolved (warning only if missing) |
| 2. vault | nothing ; will prompt for vault password and edit `vault.yml` from template |
| 3. forgejo | `FORGEJO_ADMIN_TOKEN` env var or in .env |
| 4. r720 | `FORGEJO_ADMIN_TOKEN` (used to fetch runner registration token) ; SSH to R720 with sudo |
| 5. haproxy | DNS public domains resolved + port 80 reachable from Internet ; ansible decryptable vault |
| 6. summary | nothing |
## Troubleshooting
- **Phase 3 `repo not found`** — set `FORGEJO_OWNER` to the actual
org/user owning the repo (e.g., `senke` instead of `talas`).
- **Phase 4 SSH timeout** — `sudo` may prompt for password ; configure
passwordless sudo for the SSH user, OR run remote bootstrap manually :
```
scp scripts/bootstrap/{lib.sh,bootstrap-remote.sh} r720:/tmp/
ssh r720 'sudo FORGEJO_REGISTRATION_TOKEN=… bash /tmp/bootstrap-remote.sh'
```
- **Phase 5 dehydrated fails** — check that port 80 reaches the R720
from Internet (not blocked by ISP, NAT-forwarded, etc.). dehydrated
needs HTTP-01 inbound. Test: from outside,
`curl http://veza.fr/.well-known/acme-challenge/test` should hit
HAProxy's letsencrypt_backend (will 404, which is fine ; what
matters is it reaches the R720).
## After bootstrap
- Trigger 1st deploy manually via Forgejo UI : Actions → Veza deploy → Run workflow.
- Once green, run `./enable-auto-deploy.sh` to re-enable push-trigger.
- `verify-local.sh` + `verify-remote.sh` are safe to run any time.
