+the full immutable read, emits content-addressed path-free documents and rejects
+source or definition drift before writing contracts or a queue intent.
+
+This portable definition is intentionally not executable yet. Its executor state
+is `not-installed`; no executor release or image identity is sealed. Conversion to

+mutation. A compatible recording, including RAV004, has only a successful

+The legacy RAV004 result remains independently viewable in the legacy catalog.
+The same fail-closed rule applies to every other session/setup combination.

+"""Source-independent, fail-closed Observatory RunDefinition registry.
+
+Portable definitions describe *what* a recorded K1 computation requires without
+binding it to one session, display label, filesystem path, command, environment,
+or caller-selected priority.  The registry owns every executable identity and
+recomputes every canonical digest while loading configuration.
+
+A portable definition becomes a durable ``RecordedRunDefinition`` only after
+its executor release and image have both been sealed and marked ready. Legacy
+results remain owned by the legacy LAB catalog and are not represented here.

+"""UI-ready Observatory projection for the portable LAB V1 definition.
+
+This module deliberately does not extend the legacy setup registry and does
+not submit work.  It projects two independent facts for one selected source:
+
+* the result of a lightweight recorded-source capability probe;
+* the executor state sealed by the portable RunDefinition;
+
+Keeping those facts separate prevents a compatible new recording from being
+described as incompatible merely because the executor is not installed yet.
+Historical vegetation-shadow results belong only to the legacy catalog and
+never become exact results of the generic portable v2 definition.

+"""Transport-agnostic Worker 006 core for sealed Observatory jobs.
+
+The agent accepts only the durable, path-free recorded-job projection.  It
+validates every identity sealed by Mission Core, resolves an executor from a
+local four-digest allowlist, and passes a typed job to that executor.  Server
+payloads can never provide commands, paths, environment variables, images, or
+other executable instructions.
+
+Network authentication, polling cadence, local CAS resolution, ML runtimes,
+and deployment are deliberately outside this module.  They are supplied by a
+transport and an executor adapter at the Worker boundary.
