feat(frontend): the app says what it is running, and says so honestly when it cannot find out (#3329)
#3127 checklist 12, plus rule 27 — a capability with no surface the operator
can touch is not shipped.

The step was planned on the premise that nothing read `/api/version`. Two
things did, and the state was worse than nothing:

- `App.vue` fetched it, wrote `version` into a ref initialised to the literal
  `"dev"`, and swallowed the error. An instance that could not answer rendered
  EXACTLY what a healthy local build renders. That is checklist 12's named
  failure — a blank standing in for `unknown` — in the one readout whose whole
  job is to say what is running, and it would have made #3298's debugging
  session no cheaper.
- `SettingsView.vue` fetched the same endpoint again on every mount and wrote
  the result into a local ref no template ever read. A duplicate request whose
  answer was discarded.

So this is not "add a readout"; it is "make the existing one honest, and give
it the three fields nobody could see."

The readout — Settings → Config, first section, beside the other "what is this
instance doing" facts. Three states kept apart, because collapsing any two of
them is the defect:

  not asked yet (tab unopened)   nothing
  answered                       the values, each ABSENT field as "unknown"
  the fetch itself failed        its own message, with a retry

`version` and `channel` prominent, `commit` in full with a copy button so it
can be pasted into a `:sha` lookup (rule 145 — the registry's identity and the
artifact's own must be checkable against each other), `build` kept because its
ABSENCE is the diagnostic part: no ordering key means this build is not in any
update order, which is what a local or hand-built image looks like.

Absence, not falsiness. The payload omits what it does not know rather than
sending `""` or `0` (see `build_version_payload`), so the renderer uses `??`
throughout — `build` is a number and `0` is a legitimate ordering key, which
`||` would report as unknown. `tests/test_version_readout.py` pins that
operator specifically, along with the "no plausible default" property, because
`||` is the form a person reaches for by habit.

Rule 156 — the fetch carries a deadline. This readout is consulted when an
instance is misbehaving, which is exactly when it may never answer; without one
the surface sits on "still loading" forever, which is the same blank arrived at
from the other direction. `apiGet` gains an OPT-IN `timeoutMs` rather than a
default, so no existing call site's behaviour moves. Every other call in the
client still has no deadline — reported separately, not fixed here.

No frontend test runner exists, so verification is the typecheck lane plus four
source-inspection guards in the unit lane, each pinning one property.

Also folded in: `plugin/README.md` now leads with the mint script and offers
`make` second, since `make` is not installed on every workstation.

# Scribe plugin for Claude Code
Turns a self-hosted [Scribe](https://git.fabledsword.com/bvandeusen/FabledScribe)
instance into a first-class Claude Code extension:
- **MCP tools** over your notes, tasks, projects, milestones, systems, and
rulebook (the `scribe` server).
- **Session-start push channel** — a `SessionStart` hook injects your always-on
rules + active-project context so Scribe surfaces *without being asked*.
- **Prior-art recall on writes** — a `PreToolUse` hook on Write/Edit checks the
file about to be written against your recorded snippets (what's kept at that
path, and what resembles the code) and offers them before the helper is
rewritten. Titles only, never blocks the edit.
- **Universal process-skills** — using-scribe, writing-plans,
systematic-debugging, verification, brainstorming, reusing-code (record and
recall reusable code as snippets). Replaces superpowers.
- **Your Scribe Processes as skills** — saved Processes are synced into local
`~/.claude/skills/scribe-proc-*` stubs that auto-surface by relevance; the
stub fetches the live procedure via `get_process`. Refreshed each session and
on demand with `/scribe:sync`.
It is designed so you can uninstall `superpowers` and disable auto-memory and
depend on neither.
## Install
The plugin ships inside the Scribe app repo, so the marketplace *is* that repo —
you always get the plugin version that matches your Scribe instance.
```
/plugin marketplace add https://git.fabledsword.com/bvandeusen/FabledScribe.git
/plugin install scribe@scribe-plugin
```
On install you'll be asked for:
| Setting | What |
|---|---|
| **Scribe base URL** | e.g. `https://scribe.example.com` (no trailing slash) |
| **Scribe API key** | an `fmcp_` key from **Settings → API Keys** (stored in your OS keychain) |
| **Active project id** | optional — numeric project id to scope the session-start context |
## What gets wired
- `plugin.json` `mcpServers` → the `scribe` MCP server at `<base URL>/mcp` (Bearer auth).
- `hooks/hooks.json` → SessionStart hook (`hooks/scribe_session_context.sh`),
**fail-open**: if Scribe is unreachable it injects nothing and never blocks
the session.
- `hooks/hooks.json` → PreToolUse hook on `Write|Edit`
(`hooks/scribe_prior_art.sh`) → `GET /api/plugin/prior-art`. Returns
`additionalContext` with **no** permission decision, so it can inform the write
but never stop it; silent when nothing is recorded, which is most of the time.
Two framings: a REUSE menu (similar/nearby records), and a SYNC nudge when a
snippet records the exact file being edited — "updating the record is part of
the edit" — each with its own once-per-session dedup. A third, ledger-fed
line names a duplicate family (no canon) or a canon recorded elsewhere for
the names being written (its own dedup channel, `exclude_derive`).
Fail-open but not fail-silent: a configured instance that does not answer
in time is said, once per outage ("Scribe did not answer … this write went
UNCHECKED"), so a session can tell "checked, nothing there" from "never
checked"; an answer clears the marker. The local by-name arm needs no
server and always runs. Toggle in **Settings → Knowledge auto-inject**.
- `hooks/hooks.json` → PostToolUse hook on `Bash`
(`hooks/scribe_after_write.sh`): code written through sed/heredocs/scripts
never reaches the PreToolUse hook, so this one diffs the working tree after
every Bash call (per-session path+blob snapshot; one `git status` when
nothing changed) and runs the same arms on the definitions just written,
through the same endpoint and the same dedup channels. `additionalContext`
only; never blocks, and shares the pre-write hook's once-per-outage "did not
answer" line (8 s budget here — it runs after the tool, so it gates
nothing). The extractor, the prose/data skip list, the local by-name
duplicate arm and the outage line are shared in `hooks/scribe_defs.sh`.
- `skills/` → the universal process-skills, surfaced by description match.
- `hooks/scribe_sync_processes.sh` (a 2nd SessionStart hook) + the `/scribe:sync`
command → generate `~/.claude/skills/scribe-proc-*` stubs from your Scribe
Processes (via `GET /api/plugin/processes`); also **fail-open**, and pruned to
match what exists in Scribe.
## Notes
- **Do not hand-edit `version` in `.claude-plugin/plugin.json`.** It is minted
from the clock — run `python3 scripts/mint_plugin_version.py` (or `make
mint-plugin`, where `make` is installed) after changing anything under
`plugin/`, and commit the result. The installer decides whether to refresh the cache it
executes from by comparing that string, so content that ships without a new
version reaches the repo and stops there (#2209). CI fails the lane if you
forget.
- The session-start, auto-inject and prior-art hooks need only a **read**-scoped
key; the MCP tools need **write** scope to create/update. Every hook is a GET
for that reason — a read key cannot POST.
