D-166 amendment 2026-07-21 (Jeroen, from the Groombridge/Lendel zoom captures): the seamless zoom ladder this ticket designs is now a HARD Phase-4 deliverable condition — T-750 does not close until the ladder stands (planetary map -> tile scale, every level deterministically derived at native granularity, never magnified interpolation; BHAG itself unchanged). Evidence baked into the amendment: at Lendel scale one heightmap px spans ~19 districts, so the current 16-district window is sub-pixel vs its source — beyond fit-zoom the viewer can only magnify the same composite, and the real waterline sat ~36 districts from the pixel-edge estimate (all window-scale-and-below information is D-227 invented detail and must be derived, not smoothed). This raises the design pass''s stakes: the granularity-rung ladder, wire budget, and the D-226(d) floor question are now phase-gating.

INSERT INTO tickets (record_id, type, parent_record_id, title, description, status, priority, assigned_to, team, decision_ref, created_at, updated_at, deleted_at, hash, canonical_version) VALUES ('06FR97DPEHANCYX2AC4021BSJC', 'task', '06FB0TNSRZXCHGS16BFHSSGSV4', 'Regional window legibility on quiet interiors — window-local elevation contrast', 'Follow-on from Jeroen''s first descent (2026-07-21): even with T-1142 fixed, many interior windows are genuinely one morphology zone across 66km, and the composite''s absolute lightness modulation (0.7 + 0.3 x elev_q/100, D-226 T-1124 SS5) spans only ~1-3% lightness over a window whose local elev range is small — the window reads as a dead flat fill rather than terrain. Proposal to evaluate WITH Araminta (SS5 is her encoding): window-local contrast stretch — normalize lightness within the window''s own elev min..max (fixed band, e.g. 0.62..0.92) with a degenerate floor (single-value window stays honestly flat), deterministic per window, mirroring how the aliveness_probe elev panel achieved its 12-level local texture. Alternative/complement: a faint deterministic per-cell variation or contour hinting. Any change to the recorded SS5 encoding gets a one-line amendment note. Assess AFTER T-1142 lands — real clicks will then land on real terrain and the residual flatness can be judged on coastal vs interior windows.
Scope expansion (Jeroen round-2, 2026-07-21): beyond window-local contrast, evaluate SUB-DISTRICT SAMPLING to de-block the composite at the data level — the D-227 invention fields (invent_primitives: warped envelope, scatter, character) are continuous at metre resolution and quarter granularity (512m, 4x4 per district) sits WITHIN the D-226(d) Atlas ceiling (the cap rules out chunk/tile mapping, not quarters). But classification (derive_district) is per-district today — finer sampling means a new derivation mode (e.g. sample the continuous primitives at quarter spacing and reuse the district''s classification for hue while modulating lightness/moisture per quarter, or classify per quarter at 16x the derive cost — n=32 window = 16384 quarter cells x ~7us = ~115ms background). Needs Dudley/Tyre on data feasibility + cost, Araminta on encoding. INTERIM already shipping in T-1145: linear-filtered texture rendering (presentation smoothing, no data change) — judge the residual need after both T-1145 and real-aim clicking land.
RULING (Jeroen, 2026-07-21, round-3 direction): the smooth-gradient rendering is INTERIM ONLY — he expects not to like it as the destination. The destination is SMALLER DETERMINISTICALLY-CALCULATED PIXELS (sub-district sampling, the sketch above), and the larger vision: SCROLL-ZOOM AS CONTINUOUS INFORMATION LoD — zooming in from the regional level progressively refines the sampled resolution seamlessly (no mode transition), ''zoom in to tile size from this level'' in his words. The design pass must therefore produce: (a) the granularity ladder the zoom traverses (district 2048m -> quarter 512m -> ? ), with derivation modes + per-window costs at each rung; (b) wire implications — finer windows multiply cell counts (quarter = 16x district cells/window); weigh against the windowed-family ceiling and the SS4 budget model (likely per-rung window requests reusing the same district_window carrier at different granularity, or a granularity param — design call); (c) THE FLOOR QUESTION back to Jeroen explicitly: ''tile size'' intersects the D-226(d) ceiling (chunk/tile output never Atlas-mapped; quarter is the current legal floor) — the pass presents the options (stop at quarter vs supersede D-226(d) for the window view) rather than assuming; (d) Araminta: encoding continuity across rungs (one colorizer family, hue stability as resolution refines). The COMPOSITE_SMOOTH linear-filter path ships until this lands, then is expected to be retired.
