Architect review of 8814e295..HEAD. What holds: the cosmetic-only claim is verified (every -/+ pair in the code diff is a string literal; no exit(), channel, or control-flow byte moved; the C14 usage=2/runtime=1 partition preserved at every touched site); grep gates exact (zero lowercase usage: literals, 11 'Usage: aura' source lines = 10 edited + the pre-conforming run_args_from); fieldtests corpus and refusal diagnostics byte-identical. The recorded spec deviation (3 additive house-style pins) strengthens coverage over a real pin gap and is decision-logged on the issue. Regression: cargo build rc=0, cargo test --workspace rc=0 (cli_run 133 passed / 0 failed), clippy -D warnings rc=0, doc build rc=0. No baselines exist to move, so nothing to ratify. Drift resolved in this commit: the C14 ledger note still described the casing normalization as deferred after #179 landed - rewritten to record the landed house style (usage lines 'Usage: aura <verb> ...', refusal diagnostics deliberately unprefixed). Ephemeral cycle artifacts removed per convention: spec 0101, plan 0101. refs #179
