+T05 is complete. The daily triage ActivityDefinition now uses a single trusted
+scalar `context.daily_triage_digest` instead of raw State Hub JSON. The digest
+is built in activity-core from safe identifiers, counts, statuses, priority
+fields, health labels, and shortened titles, while excluding task descriptions,
+message bodies, and other free-text command surfaces. The digest also carries a
+`deterministic_scoring` extension marker so a later high-criticality path can
+move especially high-gain/high-effort candidate scoring into code without
+changing the ActivityDefinition contract.

 Verification:
 
 - `uv run pytest tests/test_state_hub_context_resolver.py -q`:
-  5 passed
+  6 passed
+- activity-core parser validation with
+  `ACTIVITY_DEFINITION_DIRS=/home/worsch/the-custodian`:
+  parsed the daily triage definition, cron trigger, trusted instruction, and
+  report sinks
 - `uv run pytest -q` in activity-core:
-  106 passed, 1 skipped
+  107 passed, 1 skipped
