Final code review of slice 1 flagged one Important issue (the spec's
"zero cost when off" claim for the surface-dump path is technically
violated — _uploadMetadata always writes one dict entry per upload
regardless of env var) plus minor doc/consistency gaps. Applied:
1. Spec §5 "Cost when off": dropped the "Zero" claim; replaced with
"Negligible — one Dictionary write per upload (~30-50 KB at Holtburg)
plus a hash-table write per upload. Expensive work (file I/O,
histogram construction) is still env-gated." This matches reality.
2. Baseline doc §5: rewrote from "Raw logs (scratch, can be deleted)"
referencing files that were never preserved in this worktree, to
"Reproducing the measurements" with the actual PowerShell launch
commands. Honest about the raw logs not being kept; the captured
medians in section 2 are the canonical record.
3. New issue #55 filed in docs/ISSUES.md — static-entity slow path
reports ~1.45M meshMissing/5s at r4 standstill, drops to ~0 when
walking. LOW severity (no visible regression), hypothesis points
at a "permanently-missing entity gets re-classified every frame"
pattern that Tier 1 cache doesn't cover.
4. Roadmap shipped table: renamed "N.6.1" row to "N.6 slice 1" to
match every other artifact's naming. Search-discoverability fix.
None of these change the slice's conclusion or next-phase
recommendation (C.1.5 first, then reduced-scope slice 2).
