Defect A root cause: Gitea runs-list page flood (scheduled merge-robot
runs push relevant SHAs past the limit=50 first page) + collect-only-
first-page pagination -> terminal commit read as pending -> parked until
deadline. FIX: _fetch_runs paginates up to 4 pages collecting all matches
before verdict.

Defect B root cause: authority_verdict spawned deploy_qualify reading
DEPLOY_SHA from ambient env. FIX: explicit --sha arg (env masked when
sha is explicit); _ci_runs_verdict/op_ci_alive take sha as parameter
only; no env read remains in the authority path.

Defect C root cause: model sha treated as lookup key — a typo derived a
ghost operation. FIX: model sha is a HINT; unresolved sha + single
pending op -> stored target used with model_sha_mismatch logged; bound
op always wins over hints. deploy_qualify gained --sha flag (env kept
for workflow backward-compat only).

Tests: H-matrix (identity, prefix collision, env staleness,
monotonicity, aggregator lag, operation-id-first) + full 2179 suite.
