Rewrote the in-flight section to reflect that nothing is running and the
operator stood the session down. The GX10 work is recorded as what it was
asked to be: a baseline for the box and a check that the tooling loads,
with the run-3c port scoped but explicitly declined.
Added index lines for four decisions that had detail files but no pointer:
the GX10 baseline at 79.35 s/it, the costing error the operator overruled,
the althing four-surface deploy finding, and the irv-ml1 GPU resident map.
Auto-archival fired at the soft cap and moved 17 entries dated on or
before 2026-08-18 to archival-memory.md, holding back 4 that carry open
deferred-work pointers. The index went from 410 lines to 296, mostly by
rewriting in-flight rather than by archiving -- the dated log was not what
made it long.
