The asset-brief template (scope/visual-reference/naming/gen-path/ acceptance, one page) and five real briefs — station walls, rural walls, doors, floors, furniture/props — each citing its D-235 axis tokens and palette.md register rows (or the D-257 toon default), conventions.md naming/mask/footprint rules, and the image-gen -> glb-gen -> promotion path with concrete acceptance counts. Doors carry the negative no-state-frame-files constraint (runtime mechanism stays Phase 5); furniture/props' first acceptance is promoting the three unpromoted spike GLBs. deferred.md is the formal register for the T-1051 four (lamp posts, barns, TVs, billboards) + cars/Q-067, with rationale and revisit triggers — satisfying T-1051's own 'or record formal deferral' deliverable. Child stories under T-961 are created lead-side at merge. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

# Deferred Asset Classes
|
|
|
|
This is the formal deferral record for five asset classes named in the T-750
|
|
epic description that do **not** get a one-page brief this batch: **lamp
|
|
posts, TVs, billboards, barns** (T-1051's four classes) and **cars**
|
|
(Q-067). This note is what lets T-1051 close as delivered-by-deferral (its
|
|
own acceptance criterion — "author briefs, **or record formal deferral**" —
|
|
is satisfied by this file) and records the rationale so a future re-scope
|
|
pass doesn't have to re-derive it.
|
|
|
|

|
|
|
|
## The four T-1051 classes: lamp posts, TVs, billboards, barns
|
|
|
|
**Rationale.** Phase 4's cascade deliverable is "deterministic walkable-world
|
|
data + per-layer Atlas maps + asset catalog" (`CLAUDE.md` cascade table).
|
|
Outside-in generation (D-166) needs building **exterior templates** — the
|
|
D-235 wall/roof/facade/street axes — to make districts/blocks walkable and
|
|
Atlas-legible. None of these four classes are a wall/roof/facade/street axis
|
|
token:
|
|
|
|
- **Lamp posts** (street furniture) and **TVs/billboards** (signage/screens)
|
|
are set-dressing objects that populate an *already-walkable* exterior or
|
|
interior — they read as Phase 6 "detail coloring / room-level population"
|
|
(cascade table), or at best late-Phase-4 polish once exteriors exist to
|
|
place them against.
|
|
- **Barns** are a rural *building type*, not a material/form/rhythm/surface
|
|
axis token — D-235's vocabulary describes what a wall/roof/facade/street
|
|
looks like, not what kind of building a set of walls forms. A barn's walls
|
|
and roof would draw from the same `rural-walls.md` brief's tags
|
|
(`timber_wall`, `rammed_earth_wall`) plus a roof tag; there is no separate
|
|
"barn" asset class to brief independent of that.
|
|
|
|
**No partial work is lost by deferring.** T-1049's own 2026-06-12 audit
|
|
matrix confirms zero repo hits for any of the four beyond the T-750 epic
|
|
description text — no ticket, no brief, no produced asset, no style-guide
|
|
mention. There is nothing to protect or unwind by waiting.
|
|
|
|
**Disposition.** Formal deferral, not a story. No brief is authored for any
|
|
of the four this batch.
|
|
|
|
## Cars (Q-067)
|
|
|
|
**Rationale, same shape, one added layer.** Cars are also set-dressing/
|
|
transport infrastructure that presupposes walkable exteriors — same Phase-4-
|
|
vs-later argument as the four above. Cars additionally carry a genuinely
|
|
**open design question**: Q-067 ("Vehicle physics for in-world transport")
|
|
has not decided whether the game needs driveable vehicles, NPC-only traffic,
|
|
or neither, nor whether vehicle movement is client-side physics or
|
|
server-authoritative. A car asset brief would have to assume an answer to a
|
|
question that is explicitly still open — Q-067's own audit note (2026-06-12,
|
|
S-47) already flagged this: "Scope for v0.2: probably not" (and v0.2 is
|
|
dropped per `CLAUDE.md`), recommending the phase question be answered before
|
|
any car brief is written.
|
|
|
|
**Distinction from the T-1051 four, in degree not kind.** The four above need
|
|
no open question resolved — their deferral is a pure scope/sequencing call
|
|
(exteriors first). Cars need Q-067 resolved *in addition to* that same
|
|
sequencing call. Only vehicle artifact today: `spikes/3dpipeline/models/
|
|
props/vw_beetle.glb` (a spike binary, untracked per D-241 — not production
|
|
prior art).
|
|
|
|
**Disposition.** Formal deferral. Blocked on Q-067 resolution in addition to
|
|
Phase-4 exterior-generation completion.
|
|
|
|

|
|
|
|
## Revisit trigger
|
|
|
|
**Revisit all five classes when Phase-4 exterior generation is complete** —
|
|
i.e. when the tile/chunk/block cascade is producing walkable districts/
|
|
blocks with building exteriors drawn from the D-235 axes (the point at which
|
|
set-dressing has something real to populate). For cars specifically, revisit
|
|
is additionally gated on **Q-067 resolving** to a driveable-vehicles-in-scope
|
|
answer; if Q-067 resolves "no vehicles" or "NPC-traffic-only, no player
|
|
asset," the car brief may never be needed in the form this note anticipates.
|
|
|
|
## Precedent
|
|
|
|
This deferral treatment mirrors the **Q-067 precedent already established**
|
|
in T-1049's refinement history: file a scope note now, do not write a brief
|
|
against an undecided mechanic or an unwalkable world, and let the phase
|
|
cascade (D-166) — not a milestone label — be the thing that reopens the
|
|
question when its gating condition is met.

## Cross-References
|
|
|
|
- T-1051 — the ticket this note satisfies ("author briefs, or record formal deferral")
|
|
- T-1049 — parent refinement ticket; "Lead ratification" note ratifies this deferral disposition
|
|
- Q-067 — open question, vehicle physics/mechanic scope
|
|
- D-166 — outside-in generation cascade (geo → economic/exterior → building templates → door contracts → Phase-6 interiors)
|
|
- D-235 — building-exterior visual grammar (wall/roof/facade/street axes; barns/lamp-posts/TVs/billboards are not axis tokens)
|
|
- `docs/assets/briefs/rural-walls.md` — barns' actual wall/roof material draws from this brief's tags, when barns are eventually built
