Lock in the dynamic resource ownership model for runtime-spawned
resources (containers, TTYs, runner workspaces). Three decisions:
1. Storage: reuse the repo/adapter pattern (ADR-033, fourth instance
alongside IdentityProvider/IdentityStore/CredentialStore) with an
in-memory default adapter; sync read on the dispatch hot path.
2. Integration: AccessControl::check consults an ownership provider
directly (Option 2); OperationSpec gains resource_id_path (JSON
pointer into the input) so the spec is fully self-describing for
authorization.
3. Access pattern: proxy-only — spawner owns, proxy to share via
from_call + forwarded_for (ADR-032), teardown revokes. No grant
mechanism in core; 'poking holes' is a downstream-app concern. A
future grant is additive (new trait method), stated as reversal-cost
classification, not deferral.
Four edge specifics pinned: list = scope-gate + result-filter; teardown
= automatic, handler-driven; fleet = per-node ownership, downstream app
tracks 'who is this for'; composition = two orthogonal checks, ADR-015/022
unchanged.
Removes the prior hedging language ('decision direction set', 'open for
the ADR') and the contingent qualifiers from specifics 3/4 now that the
proxy-vs-grant call is made. The dependent crate specs (docker, tty,
runner, fleet) can declare their AccessControl shapes against this model.
