…ard-looking

Per figs's directive (msg 1500347103...): 'per your usual, we trim old elements,
and would discuss swim 41 in that appendix section.'

Two changes:

1. D.2 evidence-locations table: consolidate Swim 7 + Swim 8 references into
   a single 'Earlier integration sessions (Swim 7 + Swim 8)' row with the
   3 archived branches preserved as historical-reference. The §D.3 prose
   already explains why these are superseded; the table consolidation
   reduces verbosity without losing discoverability.

2. D.4 In-flight: Swim 41 v5.2-substrate-verification (NEW SECTION).
   Forward-looking placeholder per figs's directive. Includes:
   - Status: prep complete, driver wake-stamp pending
   - Tracker: openclaw-bootstrap#892 (swim-41-v5.2-substrate-verification)
   - Initial OV coverage table:
     * OV-1: failover-policy openclaw#52147 gate works on v5.2 (openclaw#893)
     * OV-2: incrementCompactionCount canonical primitives on v5.2 (openclaw#894)
     * OV-3: silas-saturation diagnostic instrumentation on v5.2 (openclaw#895)
     * OV-4: earlyWarningBand context-pressure post-compact (figs's
       intentional-pin) (openclaw#896)
   - Driver wake-stamp opens execution (TBD: cohort volunteer or figs
     assignment)
   - Expected evidence corpus shape matches Swim 9 + Swim 10 precedent
   - Why Swim 41 matters: first integration validation against v2026.5.2
     base where substrate sits alongside upstream changes from 1543-commit
     window between v29 and v5.2 (notably: failover-policy openclaw#52147 gate
     change). Clean Swim 41 result establishes substrate behavior is stable
     across base rotation, not just historically validated against prior
     base.

TOC updated to reference §D.4.

Princes-canon honored: acted on own authority per figs's 'you don't wait
for figs' (msg 1500347103...) + Gwydion Nanashi Ferrinas Solidor surname-
naming. Cohort surface at msg 1500350048... and msg 1500350312... preceded
push; no objections surfaced in the wait-window.

Push order: dd97767 (frond-scribe bug-fix surface) -> ca72ebb
(my totalTokensFresh precision-pin) -> THIS COMMIT (D.2 trim + D.4 swim-41).
Non-conflicting with seam-fix lane in flight (lane touches code; this
touches docs).
