I3310 — majordomus start refuses a task, owner or reason that the task record cannot hold, and writes nothing

Součást failure-is-visible — Každé selhání, které může runtime potkat, je omezené, testované nebo uvedené a mění zdraví, které hlásí.

Cíl

Refuse at entry, with a usage exit and no write, any task description, --owner or --because value that is multi-line, carries a control character, or would not round-trip through the layer's YAML reader; adr propose, decision add, knowledge observe and question add/resolve already refuse multi-line text through mj_is_multiline.

Proč

lib/start.sh:144 and :150 write task, owner and exemption_because into .ai/local/state/current.yaml as double-quoted scalars, escaping the double quote in task and because and nothing in owner, and lib/start.sh never calls mj_is_multiline (lib/common.sh:1788). The layer's YAML reader rejects multi-line scalars (lib/common.sh:767), so a task started with an embedded newline, a trailing backslash or a quote in --owner writes a record that the next check, handover or finish cannot parse. The refusal belongs at the boundary that accepts the text (2026-09-04 archive review). Sources: chatgpt-majordomus:c003#4.

Aktuální stav

At 707a04c, start accepts any argument text. grep -n mj_is_multiline lib/*.sh lists the callers: adr propose, decision add, knowledge observe and question add/resolve refuse multi-line text; lib/start.sh is not among them.

Cílový stav

One shared predicate judges every scalar a task command writes, start applies it to task, owner and because, and a refused start leaves no state behind.

Závislosti

Žádné. Tento úkol je kořenem grafu.

Kritéria přijetí

• majordomus start with a newline in the task exits with the usage code and writes no current.yaml
• The same refusal covers --owner and --because
• A quote, a backslash and a non-ASCII letter in the task are stored and read back unchanged by check
• A case drives each refusal and each round trip in a disposable repository

Validace

• bash test/run.sh 04_start_check
