05 — P3 DOT_C1 Registration / Catalog / Handbook — 2026-06-22

What registration requires

A dispatchable DOT_C1_* needs all of:

1. a dot_tools row (catalog),
2. a dot_agent_api_contract row with fixture_ref, output_namespace LIKE 'DRYRUN-NS:%', no_mutation_assertion=true, and a non-NULL endpoint_ref (a real no-mutation endpoint),
3. CAT-006 / meta-catalog sync, handbook/ledger entry.

The endpoint_ref requirement is structural: the dispatcher refuses DRY_RUN if endpoint_ref IS NULL ("DRY_RUN requires a real no-mutation endpoint"). The only bound DOT today, DOT_KG_EXPLAIN, points at http://incomex-agent-api-executor:8090/dispatch — a deployed microservice (incomex-agent-api-executor, Up 2 weeks, healthy). A C1 contract would need that executor to implement a C1 no-mutation route — i.e., application deployment, not a DB write.

Why P3 could not be done via a governed path here

• No governed registrar function. Function scan: INSERT INTO dot_agent_api_contract → 0 functions; the existing 2 contracts came from operator migration DOT_AGENT_API_CONTRACT_DISPATCHER_2026_06_04.
• The registrar is DOT-REGISTER (on-deploy CLI) — no execution channel here (file 02).
• No registrar Flow — [DOT-REG] flows are CDC syncs to Agent Data, not creators.
• Doing the inserts manually with the admin token / PG password = forbidden manual registry insertion (and the executor route still would not exist).

Result

P3 = no DOT_C1_ registered*. No orphan DOT created (nothing partially written). The expected DOT_C1 set (SCHEMA_ENSURE/VOCAB_BUILD/VOCAB_VERIFY/PREFLIGHT/BAD_INPUT_HARNESS/EVIDENCE_READBACK/ROLLBACK_CHECK) remains a plan to be realized by the operator registrar + executor deployment. ⇒ contributes C1_DRYRUN_CAPABILITY_LOCKED_OPERATOR_ACTION_REQUIRED (precise sub-cause C1_DRYRUN_HOLD_C1_DOT_REGISTRATION_FAILED / …_DOT_REGISTRAR_NOT_EXECUTABLE).
