10-localisation.md §10.3: the saved notes follow the box language at write time, with the one-night consequence stated rather than hidden; the globe, and the table of WHO reads which page and where its globe posts — getting that wrong makes the button do nothing, which it did on /recovery until the live probe found it. Decision 6 superseded a second time; decision 8 (a claim carries the visitor's language) recorded. Decision 5 of §11's anonymous-surface line: changing what a VISITOR reads is within what an anonymous request may do; changing anything the household owns is not, and POST /lang can do only the first. R-578 — the deadlock, and why it is a row rather than a fixed bug: UpdateOffboxStatus holds the settings write lock while running its callback, boxLang() wants the read lock, sync.RWMutex is not reentrant. On a real box an off-site run would have hung FOREVER holding that lock. The symptom was a test suite going from 8 minutes to a 25-minute timeout. Fixed and guarded, but the guard covers one package and three helper names; the class needs a gate. R-577 — a guest share visitor still has no way to pick a language, and the household's setting is the wrong default for a stranger. Deliberately left, pinned by a test, and the operator's to decide because it is a promise the share feature makes. .claude/rules/live-probes.md, unconditional: never send a deploy request for an app that is not installed, not even expecting a refusal — the endpoint accepts first and validates later. Two sessions made that mistake in two days, the second WITH a prompt line forbidding it. A prompt is read once; a rule file is loaded every session.

Live probes — what a probe may touch on a real box
One rule, earned twice in two days by two different sessions, both of which had a prompt line telling them not to. A prompt is read once; a rule file is loaded every session, which is the whole reason this file exists.
Never send a deploy request for an app that is not installed — not even expecting a refusal
POST /api/stacks/<name>/deploy ACCEPTS FIRST AND VALIDATES LATER. It answers 202 Telepítés elindítva and runs the validation inside a goroutine, so a probe that expects a refusal gets a 202 —
and if the app happens to need no required field, it is now installed on the box.
- 2026-09-17: a session probing the required-field refusal picked an app that needed no field. It
installed. Recorded in
STATUS.md. - 2026-09-18: a session that had read that record, and had a prompt line forbidding it, did the same
thing with
vaultwarden. Recorded indocumentation/audits/i18n-slice2-2026-09-18/B/live/README.md.
The lesson that sticks is narrower than "pick a different app": the deploy endpoint cannot be used to probe a refusal at all.
Instead, use a request that is refused BEFORE anything is created:
| you want to see | use |
|---|---|
| a deploy-path refusal | an app that is ALREADY installed → 409 already deployed |
| a not-found path | a name that exists nowhere → 404 |
| a validator's sentence | POST /sharing/shares with a bad name, POST /api/disks/assign with a bad mount point — both refuse before they write |
| a protected-resource refusal | POST /api/stacks/felhom-controller/remove → 403 |
If a probe does create something, remove it through the product
Not by hand, and not by docker rm: stop it, then POST /api/stacks/<name>/remove with
remove_hdd_data and remove_backups, and then verify — no container, no /opt/felhom/stacks/<name>,
no volume. Say in the report that it happened. A tidy-up nobody is told about is how the next session
learns nothing.
The general shape
Before sending anything to a live box, ask which side of the write the refusal happens on. A refusal that comes after the write is not a refusal you can probe — it is a change you are making.
