+### AMENDMENT 1 — 2026-08-08, option (a) built
+
+**Steward authorized and (a) is landed** — studium-engine `8231bce`. `reading_index_status: VERIFIED-BOUND` → **`SHA-STALE`**, with the comment carrying the full truth: which sha the index declares, which the manifest and live file carry, when it diverged, and that **the anchors hold, hand-checked**, per R0 §3. Bounded to one field, two lines; shas untouched; manifest re-parses at 14 sources.
+
+⚠ **The open sub-question was checked before choosing the value, and the answer is: the vocabulary is UNDEFINED.** Censused across both repos, all file types — `NONE-YET` ×6, `RE-ANCHORED-BOUND` ×6, `VERIFIED-BOUND` ×1 (was 2), and **no definition anywhere**. Every external mention is prose *about this defect*, never a specification. **`SHA-STALE` is therefore a fourth undefined token**, added because none of the three could state the truth — recorded as a known cost, not hidden. Whether the field survives at all is engine-lane (D-1) and rides with PENDING-121 Q2, which ruled it **not a binding surface and not evidence**.
+
+✅ **The commit was also the mechanism's first real corpus exercise:** it touched `corpus/`, so both declared rules fired — binding check passed, then the fleet ran **7 suites green**. Not a probe.
+
+**(b) remains open** — re-anchoring the index to the current text, which must carry the ladder's *re-anchor = re-verify* discipline. **Re-anchoring without re-verifying is what produced this class**, so it is not a field edit and was deliberately not bundled here.
