Three small follow-ups bundled into a single version bump:
1. Real tile.opaque consumption (cell_is_opaque_on_layer)
v0.5.0e shipped a slot-13 heuristic for vertex-painted layers
because the atlas-baker wasn't computing real opacity. Atlas-baker
v0.2.0 now sets tile.opaque via alpha-analysis (all-alpha-255
detection). Both vertex-painted and tiles[] paths now resolve the
actual slot and read its tile.opaque from atlas metadata. Pre-
v0.2.0 atlases without the flag report not-opaque (safe-
conservative: extra draws, no missed cells).
2. Manifest-schema patch (reserved fields, accept-but-ignore)
Type-checked acceptance of forthcoming manifest fields the
validator will need before consumers can ship them in real
manifests without breaking changes:
map-level: z_level (int), z_below (string)
per-layer: base_color (string #RRGGBB), tint_override (table),
collision_policy (table), traversal_modes (table),
foundation_mode (array)
Future slices (lib-core.maps v0.6 multi-z-level, lib-core.actor
movement-modes, etc.) wire the fields into actual behaviour.
3. Override format extension {slot, rot, flip} (design paper §15.1)
Override entries now accept EITHER a bare integer slot_id (compact
canonical-orientation form, backwards-compat with 0.5.0d) OR an
object `{slot, rot?, flip?}` for explicit-transform placement
(unblocks map-editor v0.2's Direct-mode Transform controls).
New normalize_override_entry helper converts disk-form to runtime
{slot, rot, flip}. Validator (validate_map_table_v3) type-checks
per-entry. set_override accepts either form and auto-stores as
compact (bare-int) when rot+flip both 0, object form otherwise —
minimises disk diff for the common canonical case. get_override
returns normalized form regardless of how the entry is stored.
draw_layer + cell_is_opaque_on_layer updated to read the
normalized form.
Closure-gate: milestone-check.sh ctest + test-all-modules GREEN.
SPOREL_CI=1 vagrant-skeleton rc=0 with 60 render_frame_ok; no
magenta-placeholders, no render-hook errors. Existing override-cells
(vagrant's 3 wall pillars) still render correctly through the new
normalize path; opaque-ceiling cache now reads real atlas data.
Consumer dep-bumps for v0.5.1 land in their own commits per repo:
sporel-lib-core.render, sporel-module-vagrant-skeleton, sporel-
module-map-editor[-test].
