Per user direction at cycle-4 close: file wd=16 (trend prediction
validation) and vertical variants (column-stride TMU behaviour
unknown) as local issues for future cycles. Progress instead to
CDEF (AV1) for codec breadth.
docs/issues/001 — wd=16 prediction validation. Per cycle 4 lesson 4,
trend says wd=16 likely flips M4 negative. Quick incremental cycle
when revisited.
docs/issues/002 — vertical variants. Different memory access pattern
(column-strided vs row-strided). The load-bearing unknown is
whether the cycle 2 +6.9% mixed gain survives the TMU coalescing
shift. If positive, deployment recipe gains symmetry; if negative,
must split by orientation.
Both issues have acceptance criteria + expected outcomes documented.
Cycle 5 next: CDEF (AV1) — codec-breadth expansion.
No Gitea repo exists for daedalus-fourier yet (project is local-
only). If a tracker is wanted, create the repo and migrate these
.md files. For now they live in-tree as part of the project history.
