chore(OMN-17241): de-register SEA from omnibase_core governance

[jonahgabriel]

OMN-17241 — de-register SEA from omnibase_core governance

Final governance site (9 of 9) in the SEA de-registration sweep. onex-self-extending-agent was archived (all 5 verdicts DEAD, project memory project_sea_is_temporary_absorb_to_canonical), but omnibase_core's validator-requirements handshake still declared it a governed repo — which kept the OCC autobind wedge class alive by minting requirements against a repo that no longer exists.

Change

architecture-handshakes/validator-requirements.yaml:

• removed the known_repos entry for onex-self-extending-agent
• removed all 10 applies_to_repos entries across the validator blocks (topic-compliance, stub-implementations, enum-governance, naming-conventions, self-gating-workflows, mypy-type-check, and the rest)
• rewrote the OMN-13579 topic-compliance comment so it no longer names SEA (omnicursor is now the only repo that comment covers)

tests/validation/test_validator_requirements_spec.py: updated the spec assertions to match the de-registered set.

The single surviving mention is the line-828 lineage comment (- OMN-13579 # onboard ungoverned public repos (omnibase, omnicursor, onex-self-extending-agent, knowledge-base)). That is a historical record of which ticket onboarded which repos, not a governance binding — deliberately retained.

dod_evidence

• Governed pre-push selector (OMN-13973) ran on the designated .200 host under the load gate. It escalated fail-closed to the full suite (is_full_suite=True reason=shared_module paths=[ tests/ ]) and then ran the impacted subset; both passed — [prepush-smart-tests] impacted tests passed; allowing push. Wall time 1h53m; no PREPUSH_* override and no --no-verify was used at any point.
• Targeted spec suite tests/validation/test_validator_requirements_spec.py: 14/14 green.
• pre-commit run --all-files: green.
• Post-change grep of architecture-handshakes/validator-requirements.yaml for onex-self-extending-agent returns exactly one line — 828, the lineage comment.
• Sibling governance sites already verified clean on merged dev/main: onex_change_control#7746, omniclaude#2086, omni_home#240.

Closes the last of the 9 governance sites tracked by OMN-17241.

📝 Walkthrough

Walkthrough

The validator registry no longer includes onex-self-extending-agent. Validator applicability and documentation-scan rollout metadata exclude the repository. Validation tests now expect three onboarded repositories.

Changes

Validator scope updates

Layer / File(s)	Summary
Repository registry and validator applicability architecture-handshakes/validator-requirements.yaml	The registry, validator scopes, and doc-content-scan metadata exclude onex-self-extending-agent.
Validation coverage expectations tests/validation/test_validator_requirements_spec.py	Tests now expect three onboarded repositories and exclude the deregistered repository from coverage checks.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: ⚪ Minimal · up to fbd75

The change removes SEA from governance bindings and updates the corresponding validation spec; the remaining follow-up is a minor test-hardening improvement, with no actionable merge-blocking risk.

Protect the SEA deregistration with a negative assertion.

The test documents that onex-self-extending-agent was de-registered, but it checks only that the three remaining repositories are present. A future re-addition of SEA to known_repos or an explicit applies_to_repos list could pass these tests. Assert that SEA is absent from both locations.
