* fix(security): screen engine-ingested external text for prompt injection The X mentions poll and the vault inbox both fed attacker-writable text (tweets, tagged notes incl. meeting-bridge output) raw into local-model prompts and CEO-facing draft payloads. The agent-sdk prompt guard's detection moves to a pure roboco/foundation/policy/injection_guard.py (prompt_guard re-exports it — grok path byte-identical) and gains screen_external_text: per-line detection where a matched line is flagged in place, never dropped, and the whole text rides an explicit untrusted-content envelope. Both engines screen once at ingestion and use the screened rendering for the model prompt AND the persisted marker/description — including the vault engine's deterministic LLM-failure fallback, which previously used the raw body verbatim. * chore(docs): reflow hard-wrapped prose inherited from the six-PR merge train * chore(foundation): regenerate lifecycle artifacts; reflow inherited prose --------- Co-authored-by: Renn F <rennf93@users.noreply.github.com>

"""Vault intake watcher: #roboco-tagged notes become board-review drafts.
|
|
|
|
Mirrors the X-engine / roadmap-engine test shape. The engine opens a PENDING,
|
|
Product-Owner-assigned, team=board draft (source=vault_note) — the intake
|
|
"Board review & Start" shape. Nothing enters delivery until the CEO's
|
|
approve_and_start: the dispatch tests prove the draft routes ONLY to the
|
|
board review, and the cap tests prove approval/cancellation free the cap.
|
|
Asserted against a real Postgres DB.
