Provisions a LAN-only browser code editor (Atheos) in an Alpine 3.23 LXC on the scotty PVE node, with armistace/blog cloned and ready to edit. Built via the AI-DLC workflow; the full process trail is in aidlc-docs/. Deliverables - scripts/provision.sh rebuild the guest from scratch (re-runnable) - scripts/update-atheos.sh move Atheos to latest upstream and RE-PIN - scripts/build-and-test.sh captures evidence for every acceptance criterion - files/atheos.conf nginx vhost (socket path byte-matches the FPM pool) - files/ssh-config ~atheos/.ssh/config deploy-key alias - RUNBOOK.md operational guide (START AT STEP 1) - docs/security-notes.md credential model + wider-web hardening TODOs - docs/resiliency-notes.md what a non-PoC deployment would need Design decisions - D1 no git identity is configured by the agent; the operator sets it. Git will refuse the first commit until then, which is deliberate (requirement FR-11). - D2 Atheos pinned to commit f90cd18 (build 611) with a verified tarball sha256, plus update-atheos.sh as the deliberate escape hatch. - D3 nginx :80, web root /var/www/atheos, php-fpm over a unix socket. - D6 git auth is a per-repository DEPLOY KEY scoped to armistace/blog, not a personal access token (a PAT's write:repository scope reaches every repo the account can write). Verified on the live guest (40 checks, 0 failures) - AC-2 Atheos served over HTTP 200 by nginx+php-fpm; socket paths byte-match - AC-3 20 posts + themes/cleanblog present; owned by the php-fpm user - AC-4 all five writable paths writable as the service user - AC-5 remote targets armistace/blog; deploy key authenticates over SSH - AC-6 survival proven with a real container restart, marker byte-identical - AC-8 no python/pelican/pip/make and no DB engine - scope boundary enforced - FR-11 git identity is empty; deploy key mode 600 owned by the service user Traps documented in the RUNBOOK (each cost real debugging time) - The Gitea SSH user is `gitea`, NOT `git` (app.ini SSH_USER=gitea). With `git`, sshd answers "Invalid user git" and rejects before reading authorized_keys, which is indistinguishable from a bad key. - The Gitea SSH endpoint is the LAN address (:22 is not forwarded publicly). - `uptime` and `free` report the PVE HOST inside an LXC without lxcfs, so a container that just restarted can claim days of uptime.

# Requirement → Unit Map — atheos-blog-lxc
|
|
|
|
**Stage**: INCEPTION — Units Generation (Part 2)
|
|
|
|
> **Deliberate substitution.** The AI-DLC rules mandate `unit-of-work-story-map.md`, which maps
|
|
> *user stories* to units. The **User Stories stage was skipped** (user-confirmed at the Requirements
|
|
> gate: "no I'm good to skip"). With no stories to map, this document maps **requirements and
|
|
> acceptance criteria** to units instead — the same assurance (nothing is silently dropped) applied
|
|
> to the artifacts that actually exist.

## Functional requirements
|
|
|
|
| FR | Requirement (short) | Unit |
|
|
|---|---|---|
|
|
| FR-1 | Alpine 3.23 LXC on scotty, 20 GB root, 2 vCPU/1 GB, onboot, unprivileged | **U1** |
|
|
| FR-2 | nginx + PHP-FPM serving Atheos; ZIP/OPENSSL/MBSTRING; `allow_url_fopen=On` | **U2** |
|
|
| FR-3 | Atheos installed, pinned, 5 writable paths, no DB | **U3** |
|
|
| FR-4 | git integration configured (git installed, `safe.directory`, identity handling) | **U4** |
|
|
| FR-5 | `armistace/blog` cloned into `workspace/` on `master` | **U4** |
|
|
| FR-6 | Remote reachable; instructions to switch to SSH; agent doesn't switch it | **U4** (build) + **U5** (document) |
|
|
| FR-7 | RUNBOOK.md with IP, SSH, workspace path, remote-switch steps, credential setup | **U5** |
|
|
| FR-8 | README.md | **U5** |
|
|
| FR-9 | Repeatable provisioning script in the repo | **U5** |
|
|
| FR-10 | LAN-only; no NPM/DNS/forward | **U2** (bind + no proxy config) |
|
|
| FR-11 | Agent creates no `armistace` credentials or git identity | **U4** (verification asserts identity is empty) |
|
|
| FR-12 | `docs/security-notes.md` + `docs/resiliency-notes.md` | **U5** |
|
|
|
|
## Non-functional requirements
|
|
|
|
| NFR | Requirement (short) | Unit |
|
|
|---|---|---|
|
|
| NFR-1 | Fits comfortably in 20 GB | **U1** (sizing) |
|
|
| NFR-2 | Survives reboot with clone + edits intact | **U1** (onboot) + **U2** (services enabled) + **U3/U4** (persistence) → verified at Build & Test |
|
|
| NFR-3 | Repeatable / idempotent-friendly provisioning | **U5** |
|
|
| NFR-4 | No K3s dependency | all (negative) |
|
|
| NFR-5 | Timezone Australia/Brisbane | **U1** |
|
|
|
|
## Acceptance criteria
|
|
|
|
| AC | Short | Unit |
|
|
|---|---|---|
|
|
| AC-1 | `pct config 136` shows Alpine + 20 GB root + onboot | **U1** |
|
|
| AC-2 | `http://<ip>/` serves Atheos (not 502/404) | **U2**+**U3** |
|
|
| AC-3 | `blog` present as a project whose files open | **U3**+**U4** |
|
|
| AC-4 | Edit + save persists to disk | **U3**+**U4** |
|
|
| AC-5 | `git remote -v` points at Gitea; RUNBOOK gives the SSH switch | **U4**+**U5** |
|
|
| AC-6 | Reboot → Atheos serves again, clone + edits intact | Build & Test |
|
|
| AC-7 | RUNBOOK lets another agent re-provision/hand off | **U5** |
|
|
| AC-8 | **No Python/pelican present** (scope respected) | Build & Test |
|
|
|
|
