EntityClassificationCache keyed by (entityId, landblockHint) tuple lands
per spec docs/superpowers/specs/2026-05-10-issue-53-tier1-cache-design.md
+ plan docs/superpowers/plans/2026-05-10-issue-53-tier1-cache.md.
Perf result (horizon-safe preset + High quality, AMD Radeon RX 9070 XT
@ 1440p): entity dispatcher cpu_us median ~1200 us, p95 ~1500 us. Down
from ~3500m / ~4000p95 pre-Tier-1. ~66% / ~63% reduction. Well under
the A.5 spec budget (median <= 2.0 ms, p95 <= 2.5 ms). No BUDGET_OVER
flag across 30s+ standstill captures.
Visual gate cleared after 4 bug-fix iterations:
- 71d0edc: namespace stab Ids globally (cross-LB id collision)
- 95ebbf3: key cache by (entityId, landblockHint) tuple (defensive)
- c55acdc: skip cache populate when classification is incomplete
- f928e66: incomplete-entity flag must persist across same-entity tuples
User-confirmed visually via +Acdream test character: NPCs animate,
multi-part static buildings render fully (no airborne geometry, no
Z-fighting, no missing parts, no wrong textures), Nullified Statue of
a Drudge on top of the Foundry renders all parts, trees outside
Holtburg render with branches present.
Closes the post-A.5 polish phase. Issues #52, #54, #53 all closed.
Tests: 1711 passing, 8 pre-existing physics/input failures unchanged.
N.5b sentinel: 112/112 throughout.
Memory: ~/.claude/projects/.../memory/project_tier1_cache.md +
feedback_cache_per_tuple_pattern.md capture the audit-gap and per-tuple-
vs-per-entity recurring trap for future cache work.
