Architect review of 88e9c9a..HEAD. What holds: token purity of the rename (removed + mapping == added, 33 sanctioned prose rewordings, numeric golden bytes untouched); CLAUDE.md invariant 7 now matches the ledger C10 section clause-by-clause; no silent alias for the old selectors (unknown-selector exit-2 path is tested). Regression: cargo build / clippy -D warnings / doc build clean; cargo test --workspace rc=0, 51 targets, 0 failures. No baselines exist to move, so nothing to ratify. Drift resolved in this commit: the C10 terminology note (INDEX.md) still called Stage-1 a surviving identifier name after the glossary recorded the rename - aligned to name the r-family rename (#174). Remaining low items: the spec's own survivor-list contradiction was ratified and recorded on the issue; the RGrid const-seeding debt is recorded on the harness-retirement issue (refs #159). Ephemeral cycle artifacts removed per convention: spec 0100, plan 0100, and the spent prior-milestone fieldtest spec. refs #174
