All six @e2e anchors CI actually runs are dangling — agent-object-leaf was never promoted out of openspec/changes/

[rubenvdlinde]

Every @e2e anchor that CI actually runs points at nothing

hermiq's measured e2e coverage of its own spec tree is 0.0%. Part of that is #176 (69
refs sit in files the CI Playwright config never runs). The other part is this, and it is
invisible to the gate:

All six refs that CI does run are dangling.

DANGLING  agent-object-leaf::a-new-finding-triggers-the-seeded-triage-flow
DANGLING  agent-object-leaf::an-unresolvable-owner-blocks-dispatch
DANGLING  agent-object-leaf::seeding-twice-creates-one-agent
DANGLING  agent-object-leaf::the-flow-contains-no-hermiq-authored-http-step
DANGLING  agent-object-leaf::the-user-is-told-the-object-contributed-no-context
DANGLING  agent-tool-governance::the-agent-may-run-exactly-one-flow

Resolved against the 735 scenario refs actually present in openspec/specs/.

Why

openspec/specs/agent-object-leaf/ does not exist. That capability's spec lives only in
change directories:

openspec/changes/hermiq-agent-leaf/specs/agent-object-leaf/
openspec/changes/hydra-console-agent-leaves/specs/agent-object-leaf/

It was never promoted into the canonical tree. Five anchors therefore point at a spec with no
canonical home. The sixth names a scenario slug agent-tool-governance does not contain.

Across the whole e2e corpus (root-config arm): 75 live refs → 59 resolve, 16 dangling.

Why nobody noticed

gate-19 does not report a dangling anchor. It is silently not-coverage
(.github#354 / #357), so an anchor pointing at a spec that does not exist reads to any
human as traceability and counts for nothing. The scenarios are also, separately, not covered
— so the spec side and the test side each look fine in isolation.

This also means wiring #176 alone will not take these tests off zero.

Suggested fix

1. Promote agent-object-leaf from the change dirs into openspec/specs/agent-object-leaf/,
   and confirm the five scenario slugs match.
2. Fix the agent-tool-governance slug.
3. Add a check that every @spec/@e2e anchor resolves — an anchor into
   openspec/changes/… dies silently the moment that change is archived, which is exactly
   what happened here.

Found while closing the E2E red in #189, and while measuring gate-19's floor and ceiling
(491 uncovered / 736 ceiling / 245 excluded).
