Records the T-1174 ruling: derive(seed, absolute world metres) via the
derive_at_metres family is the only derive core; the batch 64x32
pseudo-grid is re-scoped as a survey raster with a real SurveyCellPos
newtype (role name, not a D-243 rung); derive_district_profile becomes
a thin wrapper at survey-cell-centre positions with binding basin and
riparian preservation; point-feature terrain judgments move to exact
world positions; D-255 step canvases are fenced to the window family.
LayerRegionOutput rebuild deferred to T-1181 (tripwire verified: sole
reader is the region_grid overlay); voxel carrier deferred to Phase 5.
Consults: Tyre APPROVE-WITH-CHANGES, Dudley FEASIBLE-WITH-CHANGES —
both incorporated. Discharges the T-1174 blocker on D-255's T-1181
step-canvas envelope.

D-252 (new record, amends D-054/D-249, resolves Q-084's walk-vs-aim split):
Facing is view-only; movement no longer writes it. Client side: the rig's
moving-body yaw now always derives from leg velocity (the wire octant is the
VIEW and must never rotate the body — the follow-only commit flag
generalizes and disappears); the layered head/torso look-at runs during any
movement, WASD included; the ~100ms post-step re-assert mitigation is
removed as dead (server-side facing_from_delta removal lands separately).

D-246 (architecture): intra-class micro-habitat mosaic — a voxel_mosaic()
sub-chunk noise band modulates the D-228 axes into spatially-coherent,
relief-conditioned micro-habitats; palette keyed on surface-class ×
climate-biome × biosphere-register; five new D-228 axis values front-loaded
for determinism; within-patch believability metric in scope. Governs T-1084.
D-247 (content): habitable Reach worlds were alive before humans — the
settlement timeline forbids terraforming from dead rock. An authored per-world
chirality bit gates whether native life is edible (Compatible) or
inedible-but-inert (Mirror); "safe" and "edible" are decoupled; colonization
is ecological war that grows an Earth-crop footprint outward from settlements.
Grounds D-246's native-vs-introduced register.
D-228 amended: +Vegetation{Meadow,Deadfall,Lichen}, +TerrainMaterial{Hardpan,Scree}.

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.

D-244 ratifies what the character architecture (D-159..D-164, runtime
CharacterVisualDescriptor compositing) and the Trellis env pipeline already implied
but no decision had recorded: the in-world view renders 3D objects directly; the only
flattened 2D content is textures + flat 2D artwork (paintings/flags/billboards/signage).
There is no per-object sprite layer.
Roots out the drift: the early-spike 3D->2D sprite pipeline (#541) and the sprite-centric
docs/assets/visual catalog were never cleaned out when the project went 3D, so the
2026-06-12 fable-ous audit read them as live and re-injected the dead sprite model into
T-1049/T-1050. Fix:
- docs/assets/visual/README.md + docs/assets/README.md re-scoped to 3D models + textures
+ flat artwork (dropped the sprites/tilesets-as-entities framing).
- /sprite-gen + renderer/README repurposed as the 2D-artwork generator (paintings/flags/
billboards/signage), not the in-world object format; legacy 4-direction object-sprite
mode flagged as retired.
- T-961/T-1049/T-1050 already held in backlog pending this.

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.

Reviewing the T-1038 road-graph hub model surfaced that corp HQs are
cross-referenced into atlas_city_names as reserved rows — one per corp —
producing duplicate co-named "cities" (e.g. 10 'Groombridge' rows on
GJ380c) that the spatial layers place as separate settlements.
D-242 resolves the data model: corp HQs are not cities. The HQ relationship
lives with the corp; placement is a baked, specialization-keyed preference
(CityTenant vs Standalone, since corp_type is degenerate); population and
settlement_class are install-baked with only position seed-derived. This
supersedes the D-223 corp-HQ-cross-ref and deferred-pop/class notes.
Companion tickets under T-750: T-1074 (corp-HQ model / remove the cross-ref /
specialization map / standalone HQ settlements), T-1075 (bake per-settlement
population + settlement_class), T-1076 (road-graph hub refinement — scaled-cap
hubs, co-location collapse, hybrid minor attach, deferred RailHeadFacing pass;
blocked on T-1074 + T-1075). T-1038 annotated with shipped-vs-deferred.

416 binary files (~1.7 GB: .glb/.gltf/.bin/.png) removed from the index,
kept on disk; spikes/ keeps verdict/review markdown + spike code tracked
(61 files). .gitignore extended to cover model/texture/render binaries
under spikes/ going forward. Reproducible from purchased packs in
docs/assets/downloads/ + tracked scripts; zero markdown-embedded images
in spikes/, so no docs break. History rewrite deliberately NOT done —
recorded as out of scope in D-241. Closes fable-ous.md finding S-14.

Record D-240: a body's orbital position and stellar assignment are placeholder
registry data with no authored physical intent, so no derivation may use them as
physical inputs. Climate derives from authored planet_class (temperature envelope)
+ atmosphere + hydrosphere + seed. Supersedes the sun-driven Stefan-Boltzmann
portion of D-239 §2, which produced +356 C 'temperate' worlds (NULL spectral_class
-> G-Sun default on an M-dwarf catalog).
File T-1033 under T-974: rewrite derive_temperature_c to the class-envelope model,
drop the orbit/star inputs, regen the T-1031 golden. Audit confirmed the blast
radius is one function (derive_temperature_c).

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.
