Cycle-close audit (architect: drift_found; design core clean). What
holds, architect-confirmed with the guard run and the diff read in
full: the shell boundary is real and enforced (full-workspace
c28_layering incl. completeness + shell-content checks, acceptance
grep clean — no member-run symbol left under crates/aura-cli/src);
aura-campaign keeps zero production dependency on the runner; the IC
move is verbatim against the anchor; the new library-only E2E pins C1
(two independent runners, byte-identical RunReport).
Drift items, all resolved as fixes in this commit:
- design ledger: the C28 status sentence "No crate exists yet for
measurement" contradicted this cycle's own phase-3 done line — now
records aura-measurement as seeded (#295), execution still unbuilt.
- the #147 registry-dispatch acceptance tests (IC deflation null,
seeded determinism, cross-vocabulary refusal) were pure library
properties stranded in the shell's test module — relocated to
aura-measurement/tests/registry_dispatch.rs (engine/registry as
dev-only, layering-exempt edges), per the cycle's own tests-move-
with-their-module rule.
- aura-runner's direct production edge on the external data-server
tree was structurally invisible (the direction table checks aura-*
keys only) and unrecorded — the C28 assembly prose now names it, and
a new c28_layering test pins the external tree's entry points to
exactly {aura-ingest, aura-runner, aura-cli}.
- the C28 shell prose named three buckets that did not cover two real
shell residents — it now names the op-script construction front-end
(translation) and the `aura new` scaffolder (authoring-tooling,
shell-resident like rendering until a second consumer wants it).
Deliberately deferred, tracker homes exist (not drift): #297
(process::exit sites in aura-runner's single-run verb paths), #294
(IC duplicate-timestamp semantics), #288-era rustdoc unresolved-link
warnings in aura-std/aura-backtest (pre-existing byte-identically at
the anchor).
No regression scripts are configured (the bench is report-only); the
architect review is the gate. Verification: cargo test --workspace
green (1474 passed, 0 failed) incl. the relocated registry-dispatch
tests and the new data-server guard; clippy --workspace --all-targets
-D warnings clean.
