## felhom-host-install.sh v1.2.0 — /dev/tty passphrase read + vmid auto-detect (2026-07-01)

Two operator-experience fixes so a colleague can install online (via the hub's new "Option 1: Online
install" one-liner) and onto a host that already runs a guest at 9201.

- **Passphrase prompt reads from `/dev/tty`, not stdin** (`read_passphrase`). `read -rsp … < /dev/tty`
  makes the no-echo prompt work regardless of how stdin is wired — both download-then-run **and**
  `curl … | sudo bash` (where stdin is the pipe). Strictly more correct; the `--passphrase-file` path is
  unchanged. The passphrase is still never on argv / in logs / in the state file.
- **VMID auto-detect (`--vmid` now optional-smart).** New `VMID_EXPLICIT` flag (set by `--vmid`). The
  pre-flight vmid guard now determines "in use" against the **`pct list` + `qm list`** id-set (LXC and
  VMs share the id space — more complete than the old `pct status`, which only knew LXC):
  - **explicit `--vmid`** → unchanged deterministic behavior: die if the id is in use unless `--force`
    (destructive over-provision).
  - **default 9201, in use, no `--force`** → **auto-pick the next free id** (scan upward from 9201 over
    the used-set) and **ask to confirm** from the terminal (`read … < /dev/tty`, `[y/N]`); proceed on
    yes, `die "no free vmid confirmed"` otherwise. Never a silent auto-pick.
  - **default 9201 + `--force`** → over-provision 9201 (destructive) without prompting, as before.
  - New helpers `used_vmids` / `_vmid_in_use` / `next_free_vmid`. `--vmid` help text + `usage()` updated.

## felhom-host-install.sh v1.1.0 — self-install the agent + fetch the golden from Gitea (2026-06-28)

The script now **installs the agent itself** (the last big manual Day-0 prerequisite is gone). It
fetches the agent binary + golden from Gitea generic packages and **verifies each against the
hub-vouched artifact manifest** before installing/using it. BUNDLE slice; pairs with hub v0.16.0
(artifact manifest endpoint + operator UI) and felhom-agent v0.43.0 (canonical unit + publish).

- **New step `5/8 agent install`** (before agent-config): resolves the manifest
  (`GET /api/v1/artifacts/{id}`, passphrase) + the git fetch token (from the customer's
  `controller.yaml` via config-retrieve — **NO new credential**); fetches
  `/api/packages/admin/generic/felhom-agent/<ver>/felhom-agent`, **verifies sha256 vs the hub
  manifest** (aborts on mismatch — verify-before-use), backs up any existing binary, installs
  `0755 /usr/local/bin/felhom-agent`; ensures the non-root `felhom-agent` system user; installs the
  canonical sudoers (`0440`, `visudo -cf`-validated) + systemd unit; `daemon-reload` + enable. Idempotent:
  same version already installed + service active → skip.
- **`--skip-provision`:** install + configure + verify the agent (incl. golden fetch+verify) but do NOT
  provision a guest — the agent-only path for re-installing/upgrading the agent on a host that already
  has live guests. Adds an agent-only `step_verify_agent` (binary + non-root service active + a
  `--selftest=hub` collect-report).
- **New step `7/8 golden`:** local auto-discovery stays the default/fallback; otherwise fetches
  `/api/packages/admin/generic/felhom-golden/<ver>/golden.tar.zst`, **verifies sha256**, and imports it
  into the archive storage's dump dir for the restore. `--force-gitea-golden` forces the Gitea path.
- **Non-root agent model:** the agent now runs as `felhom-agent` with `privileged.mode: "sudo"` (was the
  dev/CI `direct`+root shortcut). The config is `chown`ed to the service user (0600) so the daemon can
  read it; `systemctl is-active` after restart is the real proof the non-root user can read the config.
- **Pre-flight relaxed:** a missing agent binary is no longer fatal (step 5 installs it); the local
  golden requirement is deferred to step 7.
- **Trust model:** checksum **trust root = the hub** (manifest), not Gitea; the fetch credential is the
  existing config-retrieve git token; artifacts are pinned to a version (never `:latest`).
- **Secrets:** the git token is a never-logged runtime carrier (cleared on EXIT alongside the passphrase
  / pve-token / hub api_key); the sudoers is `0440` and `visudo -cf`-validated before install.
- `bash -n` + `shellcheck` clean.

## felhom-host-install.sh v1.0.0 — Day-0 host bootstrap (provision mode) (2026-06-26)

First release. A single operator-run script that automates Day-0 on a freshly-PVE-installed
host: Proxmox API token → hub host enrollment (option C, single secret) → agent config →
guest provision → verify. Composes proven mechanisms (the `pveum` role/token sequence, hub
`POST /host-enroll`, `felhom-agent --selftest=provision`); grounded by
`documentation/audits/SPIKE-day0-firstboot-handshake-2026-06-26.md`.

- **7 steps, idempotent + resumable** via `/var/lib/felhom-install/state.json`: pre-flight →
  Proxmox token → compute grows → host-enroll → agent config → provision → verify.
- **Single-secret** (the retrieval passphrase): read no-echo or from a 0600 file, never on
  argv/logs/state. The global operator key never touches the box.
- **pveum automation:** 16-priv `FelhomAgent` role (create-or-modify), `felhom-agent@pve` user,
  privsep token (reuse-if-working else rotate), and **both** ACL grants applied **after** the
  token exists (token-remove purges the token ACL).
- **Auto-discovery:** golden archive (newest `vzdump-lxc-<golden-vmid>`), PVE node name, vmbr0
  bridge IP for the local-api, and the served-leaf TLS fingerprint pin.
- **Safety:** pre-flight fails fast (root, PVE 9.x, local-lvm headroom, hub reachable,
  customer+passphrase valid via read-only `GET /config/{id}`, golden resolvable); refuses to
  clobber an existing `--vmid` without `--force`; `--dry-run` previews every mutation;
  `--preserve-from` keeps operator infra (PBS/local_api/privileged/authz) on re-deploys.
- **`--mode dr`:** documented 10D stub (restore customer PBS snapshot instead of golden) — not
  implemented.
- **Live-validated** end-to-end on `felhom-pve`: authorized wipe of demo guest 9201 →
  re-provision from the golden → controller config-pull + public tunnel `HTTP 200` →
  host-report of guest 9201 → idempotent `--resume` no-op. (One ordering bug — token ACL
  applied before rotation — was found and fixed during the live run.)
