chore(memory): Basic Memory trial begins — sync normalization baseline (283 files)

Basic Memory v0.21.6 first sync over the live memory dir (steward-authorized
live-dir trial, Option A 2026-06-06): adds permalink: to frontmatter, refolds
long YAML description lines, strips final newlines. Bodies untouched —
verified via full diff classification. From this commit forward, any diff in
claude/memory shows only what Basic Memory or the session writes.

Trial design: MemPalace untouched as incumbent; git status check on this dir
at every wrap; end-of-day evaluation (recall quality, sync robustness,
rebuild-from-files, malformed-file behavior).

 - 2026-05-27T~19:35 — Dispatched 3 read agents (L1 spec / L1 runtime / Hindsight code) under Symmetria §5 preamble. All three returned dense, well-cited, source-grounded. §5 audit: CALIBRATION honest (each marked verified-vs-inferred + could-not-confirm); CONVENIENCE — none stopped early, all surfaced inconvenient findings (Hindsight code≠paper; "Amendment 61 overstated for the epistemic layer"); SCOPE — surfaced beyond-ask (Agent A challenged the binary framing; Agent B flagged the dead similarity probe as a [HARDENING]). Verdict: ACT after my own verification of the 3 load-bearing claims.
 - 2026-05-27T~19:45 — VERIFIED against source (counter to assert-from-inference drift): (1) Hindsight opinion+confidence_score+CARA REMOVED — migration `g2h3i4j5k6l7_remove_opinion_fact_type.py` verbatim (DROP COLUMN confidence_score; CHECK→world/experience/observation); per-unit link caps real+tested; no reinforce/cara in engine. Shipped ≠ paper. (2) L1 `setSimilarityProbe` zero callers → observation-recall coupling DEAD in checkout `3bc8b75`. (3) L1 `earned_confidence`+`means_of_knowing` written in classification, read by NOTHING in query-router/synthesizer → orphaned at recall (the numeric confidence scalar IS threaded live; the qualitative epistemic kind is not). All three hold.
