# iter embedding-abi-m2.tidy — lockstep section rename `Embedding ABI (M1)` → `Embedding ABI`

**Date:** 2026-05-18
**Started from:** d1241b12c759765f12713584ce2aab21e2a74f74
**Status:** DONE

## Summary

Audit-driven docs-honesty tidy (no parent spec; source:
`docs/journals/2026-05-18-audit-embedding-abi-m2.md`, the M2
milestone-close audit). The DESIGN.md section `## Embedding ABI (M1)`
had a stale `(M1)` qualifier — its body now describes the post-M2 ctx
ABI present-tense, so the qualifier contradicts the current-state-mirror
discipline. Renamed the header and moved all four *live* coupled
references in lockstep so no pointer dangles at the vanished `(M1)`
title. Pure docs/test-string tidy: zero language / checker / codegen /
schema change; `ail check`/`run` byte-unchanged by construction. The
`docs_honesty_pin.rs:135` asserted substring is rename-immune (no
section-name token, matched file-wide via `d.contains`) and was left
byte-verbatim untouched; the pin staying green before AND after
empirically confirms the rename did not perturb it.

## Per-task notes

- iter embedding-abi-m2.tidy.1: lockstep rename across 5 live-coupling
  sites in 3 files — `docs/DESIGN.md:2266` (section header) +
  `docs/DESIGN.md:2354` (schema-block xref comment) +
  `crates/ailang-core/tests/docs_honesty_pin.rs:134` (test comment) +
  `:136` (assert-message) + `crates/ailang-core/specs/form_a.md:89`
  (compiled-in forward-xref). Each site: one-line in-place `(M1)`-token
  deletion, no reflow. Step-1 baseline grep showed exactly the 5 sites
  present (`:135` correctly absent — no `(M1)` token); Step-6 grep
  returned zero (exit 1). `docs_honesty_pin` 5 passed and
  `design_schema_drift` 8 passed both before and after. Footprint
  gated at exactly 3 files, 5 insertions / 5 deletions — no
  `docs/journals/**`, `docs/specs/**`, `docs/plans/**`,
  `bench/orchestrator-stats/**` touched (committed append-only history
  retains `Embedding ABI (M1)` as correct record of the name at the
  time; renaming it would falsify the record).
