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).

D-248 (architecture): per-leg constant-velocity interpolation keyed to the
stance throttle; cadence-synced gaits; one smoothing layer per channel;
annotates D-054 (its 100-150ms tween scoped to the 2D renderer).
D-249 (architecture): 'server feet, client eyes' facing split with the
verified octant-to-yaw table and the set_facing() trap note.
D-250 (perception): wall cutaway is client camera presentation, decoupled
from fog-of-perception; fog-memory-for-geometry nuance parked for Phase 5.
D-251 (content): Quaternius rig reconfirmed after full 2026 re-evaluation;
Synty intake technically proven then product-rejected; in-house wardrobe
routes; UAL paid tiers close the animation gap; revisit tripwires recorded.
Annotations: D-148 editorial note (preset list authoritative; stepped camera
yaw needs a record), Q-020/Q-063/Q-079/Q-084 updates.

The push gate's integration tests (not in cargo test --lib) caught two regressions
from the relief change:
- derivation_harness::cross_district_elevation_blend_reduces_seam_step — the relief's
large per-position term (span 300 → ±200 m, far above the compressed elev_q/2 base)
swamped the T-1042 seam measurement and clamped heavily at sea level. Fixes:
(1) shift the voxel-relief octave band to 0.13–1 km (all sub-district, dropping the
2 km octave that competed with elev_q's district role); (2) reduce VOXEL_RELIEF_SPAN_M
300 → 100 so relief stays mostly below the base (fewer sea-level clamp artifacts,
proportional hills); (3) rewrite the seam test's avg_elev to average over an 8 km
multi-wavelength y-transect so the zero-mean relief cancels, isolating the base seam.
- derivation_harness::golden_seed_determinism_regression — legitimate golden refresh
(determinism still holds; elevation values changed intentionally).
Believability relief now ≈22 m mean (was 5 m flat; 59 m at the over-aggressive span 300)
— navigable hills without clamp artifacts, 7/8 criteria. Both goldens regenerated; full
cargo test (38 binaries) + clippy --all-targets -D warnings green. D-239 amendment +
Q-123 item 4 updated to the final span/octave/numbers.

T-1081 review (Hoshe + Tyre): the seed_domain_discriminants_are_pinned test (the
D-224 guard that fails CI if a variant is renumbered — which would silently re-roll
every world's relief field) did not pin the new VoxelRelief = 11. Add the assertion.
Also fold Tyre's two Q-123 calibration notes into item 4: (i) sanity-check the
slope_q*3 + elev_q envelope on a synthetic high-slope body (both terms cap at 100);
(ii) the relief transect is a single diagonal slice (fine for isotropic fBm, revisit
if an anisotropic ridge field is added).

The voxel tier read flat (the D-245 "0–3 m, no hills to navigate by" bug):
family generators set elevation from elev_q at a compressed scale plus only ±4 m
micro-scatter, and detail-scatter's mid-scale relief (D-243 §2) only ever reached
the district tier (elev_q), never per-voxel elevation_m.
- detail_scatter.rs: extract the enveloped-fBm core; add `voxel_relief` at the
0.25–2 km octave band (vs the district 4–40 km band).
- voxel.rs: add the mid-scale relief post-dispatch in derive_voxel_column, body-global
SeedDomain::VoxelRelief seed (position-keyed), f64 truncated to integer metres (D-010).
Envelope = slope_q*3 + elev_q — the coarse heightmap gives slope_q ≈ 0 even on high
ground (Arbour max 13), so elevation must drive ruggedness. Flat families only
(Alluvial/Lava/BraidedDelta/Dune/Meander); the dramatic families already carry strong
internal relief and WaterBody stays at sea level.
- seed.rs: SeedDomain::VoxelRelief (D-224 domain separation).
- believability.rs: new `contrast.voxel_relief_m` metric — mean within-district elevation
range over a 2 km transect (a single 64 m sample chunk is narrower than the relief
band) + a "voxel relief" criterion.
Arbour @ yolo: voxel relief 5 m → 59 m, 6/8 → 7/8 criteria (remaining fail = the
Q-123 vegetation-denominator item). Edict 59 m. Golden regenerated; 1586 lib tests +
believability harness (determinism) pass; clippy -D warnings clean.
D-239 amended (T-1081); Q-123 item 4 updated. Deferred to Q-123/follow-up: the
provisional span + threshold, and a per-body hypsometric absolute-elevation model.

Stack review (Hoshe + Tyre) of T-1083+T-1082+T-1080. Every finding fixed or disposed:
- believability.rs sample_indices: replace the rejection-sampling loop (could stall
when n ≈ take) with deterministic partial Fisher-Yates — O(n), guaranteed
termination, distinct, sorted (Hoshe+Tyre).
- believability.rs drainage proxy: exclude water-body districts (all elev 0, no banks)
and require both wet + dry voxels — they were passing vacuously and inflating the
metric (Hoshe).
- believability.rs read_cities: log skipped malformed rows instead of dropping silently
(Hoshe).
- voxel.rs: add the 3 WaterBody zones to all_families_no_panic_at_extreme_positions +
fix the "7 families" comment (Hoshe).
- climate_constants.toml: bold warning that [moisture_gradient] is not loaded until
T-1032 — tune ClimateConstants::default() (Tyre).
- Q-123: record the per-zone "water renders wet" threshold + the land-relative
vegetation-present denominator as calibration items (Tyre + the open 7th criterion).
- T-1083 ticket: note the sampling-fix attribution (landed in the T-1082 commit).
Believability golden regenerated (sampler + drainage fixes moved the metrics).
clippy --all-targets -D warnings clean; 1580 lib tests + harness pass.

Lock the cascade's nature-half deliverable to "reads alive anywhere", not
"implemented" — the holy-grail objective surfaced by probing the generation
cascade.
- D-245 (architecture): the nature layers are accepted only when the
believability litmus passes at randomly-sampled locations across all
habitable bodies/seeds — multi-scale + never-repeating (macro identity,
meso non-stationarity, micro mosaic), coherence + non-stationarity +
intra-class variety + relief + climate-appropriateness, automated screen
under a human sign-off, budgeted -> strict. Q-123: threshold calibration.
- T-1079 (epic, north-star, DoD=D-245) + findings T-1080 (uniform climate
fields), T-1081 (near-zero relief), T-1082 (no water-body generator),
T-1084 (intra-class micro-habitat mosaic), and T-1083 (the repeatable
believability test protocol / D-245 enforcer).
- aliveness_probe bin: the exploratory probe that found these (runs the
deterministic cascade for a body+seed, reports per-district nature +
verdict). Seed for T-1083.

Resolves Q-110 (region/chunk physical-scale anchoring), which had three
contradictory metres-per-scale assumptions in the cascade and no record
fixing metres-per-heightmap-pixel.
D-243 establishes a nested absolute-metre containment ladder with a single
elastic seam at planetary scale:
voxel 1m -> chunk 64m -> block 128m -> quarter 512m -> district 2km
-> region ~205km (100x100 districts) -> (elastic) -> planet
A body holds round(2*pi*R/204.8km) regions (the only per-body-floating
quantity); everything below is fixed integer math, so ChunkPos->RegionPos
is body-independent. The region is the largest hard block: the climate/
weather/season lockdown scale (the Q-105 cheap-dynamism source) and the
sane planetary grid. Sub-heightmap detail is invented deterministically
(interpolation + domain warp + detail-scatter, never stored, D-227); climate
is edge-fuzzed so the grid never shows ('climate does not change on a line').
Vocabulary locked and recorded in CLAUDE.md: 'region' = the 205km metric
cell only; the old 1km RegionProfile is dropped onto the 2km district; D-201
tier-4 'Region' renamed Province (the watershed/political overlay), amended
here. Refines D-239 §2 (district temperature now modulates a region baseline).
Implementation tickets: T-1077 (re-scale the code to the ladder + elastic-seam
resampling; blocks T-1046) and T-1078 (region climate stack + edge fuzz).
T-1046 is un-gated on Q-110 and now blocked only by T-1077.

Adopts the T-NNN convention (T-N == old #N == pql ticket id) across the active
operational layer: governance/ decision records, .claude/{rules,agents,skills},
CLAUDE.md, DECISIONS.md. 283 references rewritten.
Guarded against false positives (17 correctly skipped, each logged):
- PR references kept (PR #136/#138/... — PRs are a separate #-namespace)
- non-ticket numbers kept (#4122; the "#1 process failure" idiom; "task #3")
- only #N where N is an actual ticket id is rewritten; the 1-4 digit word-bounded
match also excludes 6-digit hex colours in the visual decision records
Git history is NOT rewritten (a commit's #N already equals T-N numerically), and
historical archives (docs/sprints, docs/discussions, docs/workshops) keep their
point-in-time #N. The /pr-process ticket-ID extraction logic moves to T-NNN in the
Phase 4 consumer cutover.
Verified: pql decisions validate ok; sync 357 records / 1057 refs / broken 0 (the
prose edits don't affect decision parsing or the tickets.decision_ref linkage).
Transform committed at tooling/pql-migrate/retag_ticket_refs.py.

Phase 1 of the pql migration. Moves the flat decisions/*.md layout into
governance/{decisions,questions,rejected}/<domain>.md — the tree pql's
`decisions sync` parses natively (record type from subdir, domain from
filename stem). Proven against pql 1.6.2: sync reports 357 records
(237 D / 108 Q / 12 R), 1057 refs, broken: 0; validate ok.
- 6 D-domain files -> governance/decisions/ (git renames)
- 5 questions-<domain>.md -> governance/questions/<domain>.md (prefix dropped)
- rejected.md split by domain -> governance/rejected/{architecture(R-001..010),
economics(R-011),perception(R-012)}.md
- decisions/README.md + questions.md index folded into governance/README.md;
pql's `decisions sync` now auto-maintains the record index appended below
the hand-written domain guidance (no more manual ID-list table upkeep).
- .pql/config.yaml: canonical vault config (tracked, not ignored).
Link rewrites are token-preserving: only the relative `foo.md` path portion
changes (e.g. `rejected.md#r-011` -> `../rejected/economics.md#r-011`); every
`[D-NNN]` bracket text and `#anchor` stays byte-identical, so pql's reference
extraction is unaffected. The one-shot transform is committed at
tooling/pql-migrate/restructure_decisions.py for provenance.
Codebase path references to decisions/ (CLAUDE.md, rules, skills, docs) are
updated in a follow-up commit.
