docs(meta): secure the cascade as the Phase-5 walkable-world mechanism (D-012 amendment)

Browse Source 
Jeroen's gap catch: T-750 never stated that the seed-to-tile cascade is
also what determines the world where the player walks. Now connected in
one statement across three homes: D-012 amendment (the founding 'chunks
load/unload around the player' driver now concretely = the D-227/D-239
cascade; 3x3 chunk neighborhood minimum, coarser context self-provided by
D-255(f) function composition, Atlas interaction never a precondition,
byte-identical either way), the matching T-750 deliverable note (in
changelog), and a one-truth consumer note on Q-093 for the Phase-5 insert
minimap (design deferred, no independent map pipeline expected).

PREP SESSION COMPLETE + BRIEF SIGNED OFF (2026-07-25, Jeroen + lead + Tyre). Jeroen''s design outline captured and clarified over two AskUserQuestion rounds; Tyre delivered governance-delta/implications pass and ratified the brief (zero misrepresentations, zero blocking gaps). Signed-off workshop brief: docs/workshops/body-map-viewer/body-map-viewer-workshop-brief.md (session artifacts: jeroen-outline.md, clarifications.md, tyre-implications.md, prep-grounding.md in the same dir). Settled premises: server-side content determination per zoom step; client map-art function; RTT terrain + screen-space vector annotations baseline (locks T-1176 candidates b+a; c1 styling open); GPU presentation-only; stepped zoom (supersedes continuous — recorded at workshop filing); tile=1m only, ''gridunit (at zoom level)'' coined; data resolution tunable (1px ideal, 5x5 fallback); hydrology = deterministic equilibrium; client-primary cache (store shape open: server-side SQLite cache / godot-sqlite / file cache — SQLite ships in the Rust server, NOT the Godot client). Workshop: 5 seats (Dudley/Araminta/Stig/Tyre + Troblum r2), 2 rounds + lead interview, extendable at Jeroen''s call, round 1 GATED on measurements — see blocker edges. Expected Output 2 mandates an explicit deprecation sweep (Clerk audit) of all conflicting DQR records/tickets at filing.
