# 0.1.25: re-exports rotaryengine 0.1.12's new `chunk_revolver` coalescing surface.

# Standalone workspace: extracted from the znippy repo into its own leaf repo so
# both skade (stree/gatling) and znippy (codecs/gatling) depend on it without a
# release-cascade cycle. The codec sub-crates moved here from the deprecated
# standalone `*-rs` repos.
[workspace]
# `znippy-zoomies-build-thing` is this repo's `impl BuildThing` (lane AG,
# 2026-08-30) — a member, not a dependency: nothing shipped links it. It exists so
# `.nornir/build-variants.toml` can be EMITTED from code instead of hand-written,
# and dwarves' forge finds it by package name at the repo root (one of the two
# places it looks; this workspace has no `crates/`).

[features]
# `vann-mmap` WAS DECLARED HERE AND GATED NOTHING. It promised that
# `vann::ragnars_emb` could memory-map its int8 row blob instead of holding it
# resident; measured 2026-08-22, `src/vann/` has **zero** `cfg(feature = "vann-mmap")`
# sites and does not name `memmap2` at all, and no manifest anywhere in the
# constellation ever enabled it. A flag that compiles nothing either way is worse
# than no flag: a reader takes it for a capability, and a feature-coverage gate takes
# it for ground somebody is watching. Deleted rather than allowlisted — an excuse
# would have made it permanent. If the mmap path is ever written, the flag comes back
# WITH it.
# `testmatrix` — turn the crate's `functional_status(component, check, ok, detail)`
# self-reports (the gatling engines' run markers) into real nornir test-matrix
# rows. Compiled OUT of the default build (no nornir dep by default); pulls
# nornir-testmatrix's own `testmatrix` mode so the emit is a row-append, not a
# no-op. Additive and no-op unless explicitly enabled.
