Architect drift review (f68258b..HEAD) found no code drift — the firewall is
real at the dependency-graph level (aura-core/std/engine/cli carry no external
dep; the chrono/regex/zip tree is confined to aura-ingest), and C3/C7/C1 are
faithfully realized. Four ledger-level items, all resolved here:
- [ledger-drift] The zero-external-dependency commitment — the load-bearing
rationale for making aura-ingest a crate rather than a feature-gate — lived
only in spec 0011. Recorded in the ledger: C16 now states the engine workspace
is zero-external-dependency by commitment, names aura-ingest as the ingestion
edge / external-dependency firewall, and forbids an external dep in any engine
crate other than aura-ingest.
- [ledger-drift] C16's reuse taxonomy did not place aura-ingest. C16 now lists
the non-node engine crates (aura-engine, aura-cli, aura-ingest).
- [ledger-debt] C12's eager-materialization-now / Arc<[T]>-sharing-later choice
was only in the spec. C12 now carries a "Status (cycle 0011)" note recording
the deliberate gap.
- [debt] aura-engine/Cargo.toml carried a stale comment ("data-server enters
when the ingestion task starts") that contradicted the firewall it should
protect. Replaced with the dependency-pure / firewall-in-aura-ingest note.
The External components data-server bullet is updated to reality (pulled in by
aura-ingest; workspace now resolves from a populated cargo cache, not fully
offline).
Regression gate: no-op (commands.regression empty); architect is the sole gate.
Cycle 0011 is drift-clean. (Drift-clean, not a milestone close — the
Walking-skeleton milestone close additionally needs its end-to-end milestone
fieldtest, a separate deliberate act.)
