 *Note: measure-don't-speculate (ch2 date-range story) is NOT proposed — already carried by the ladder (censused-routes, measure-toolchain-before-spec). Today's census re-proved it; no new instrument needed.*

+## New proposals (2026-06-08 evening — the tree + the memory-index archive pass)
+
+**Verification-ladder additions (the session proved both; → `reference-verification-ladder.md`):**
+- **content-multiset-identity gate (file-split/extraction under @layer)** — when a refactor *moves rules between partials* (not just reorders one), the byte-identical compile gate FAILS: each new partial adds a legitimate `@layer base { }` wrapper. The correct proof: strip `@layer …{` openers and lone `}` lines, sort, diff → identical content-multiset proves no rule changed/added/dropped while the wrapper count differs as expected. Proven 5× (the `_utilities` dissolution). PROPOSED.
+- **CAUTION: property-name-exact collision measures miss shorthand↔longhand + cross-selector-same-specificity** — the `.ornament` margin flip (`margin` shorthand vs `margin-top/bottom` longhand) was invisible to the automated `/tmp/collide.py`; only the source-read caught it. The automated census is the floor; the per-move render gate is the guarantor (byte-identical≠rendered-identical, one layer down). PROPOSED.
+
+**Memory-index (MEMORY.md) — the archive pass + the durable fixes:**
+- **DONE 2026-06-08 (steward-authorized, live): compress-in-place archive pass.** 90 archived-session bullets compressed to one-line pointers (detail preserved in the session files), **285KB→157KB**, all 239 pointers preserved, every load-bearing section byte-identical; backup `/tmp/MEMORY.md.bak`. ⚠ A naive split-at-first-`## Archived` was **caught-and-avoided** — the file is INTERLEAVED (archived blocks scattered among load-bearing reference sections: Pending work / Feedback / Drift patterns / ARC project state / CapableMind L1 / Personal Context / Reference Files). Surgical compression of only archived bullets is the correct tool for an interleaved index.
+- **[PATCH proposal] `/wrap-up` §3 — compress at demotion.** When demoting Active Session → Archived, compress the entry to a one-liner in the *same move* (it's already in the session file). Prevents index re-bloat at the source — without it the index re-grows ~4–5KB/session and this pass recurs.
+- **[PROPOSAL] deeper MEMORY.md reduction (only if 157KB still trips "only part loaded").** The load-bearing REFERENCE sections (steward profile / project states / ARC project state / CapableMind L1 / Reference Files) are large but largely STABLE — candidate to move to a consult-on-demand `MEMORY-reference.md`, leaving the wake-loaded MEMORY.md = standing prefs + trackers + Active Session + recent. Riskier (real memory, not duplication); its own focused pass, not a tail-of-session move.
+- **[reminder] the wake-canary** (PROPOSED 2026-06-07, above) still awaits authorization — the paired guardrail (every MEMORY.md pointer + `[[link]]` resolves at wake); should cover MEMORY.md + any future archive/reference split files.

 *Discipline reminder: "no harvest" is a valid outcome; do not manufacture proposals to fill the table (the inverse of Hermes's autonomous self-write). The yardstick is the steward's: did the steward have to re-explain something a skill could have carried?*
