zone painter: record the bind/unbind/no-smooth milestone in the patch-edit plan Part 1 gains the first Tier B milestone entry (ops, group semantics, the closure-restricted bind snap and why, the Patch rollout, the m40 gates); Part 5 ticks the explicit-unbind item, marks the rollout started with the remaining spec items listed, and adds the deferred bind command mode.

zone_painter: reference spec of the legacy patch-edit rollouts Inventory of the legacy modifier's command-panel UI: rollout stack and placement, per-level enable rules, spinner ranges, right-click additions, modal dialogs, and icon and cursor motifs.

zone_painter patch edit plan: record the 2026-07-28 review pass (input-path fixes, TU split)
Zone painter patch editing: handles, transforms and pivot modes Records the handle interaction rule (handles win when both sets are non-empty, because the corner selection has to survive picking a handle), the W/E/R key resolution, the pivot modes, and that the gizmo now sits on the pivot. Also records why the M35-6 render assertion was replaced with a count: it was unsound rather than fragile - in the welded build the shared CTessVertex holds whichever patch refreshed last, so the pixel diff tracked refresh order, not the weld. Worth keeping as a shape to recognise.
Zone painter patch editing: welds are a paint relationship Records the finding that drove the change: CZone::compile does not merely bind welded zones, it aliases their corners into one CTessVertex, so a patch edit that breaks a seam is structurally invisible - the render shows a surface neither .max describes. Patch mode now builds the zones apart and the seam shows. Seam propagation is gone; the open workflow question it raised is closed with it, since across a session's welds the same edit meant different things depending on which files were open, and a ligo border profile is a contract across every brick sharing that edge type rather than a pairwise fact. Also folds the two rebuild paths into one rule: bind data cannot come from the retrieve either, because that reflects how the zone is built right now.
Zone painter patch editing: rewrap
Zone painter patch editing: tidy the gizmo paragraph
Zone painter patch editing: edge and patch sub-object levels Records what shipped and, more usefully, the two things that were not obvious: - The level's own selection set is the authority and the vertex set is a projection recomputed from it, which is what makes dropping one of two edges that shared a corner keep that corner. Written down because add/remove-two-vertices looks equivalent and is not. - The cage needs two draw passes. A shared edge is drawn once per patch, so a single pass let the neighbour drawn later paint over the highlight and a selected patch came out half red depending on patch order. Also notes why edge picking follows the drawn Bezier chain rather than the straight line between corners, adds the m36 gate table, and reframes the Tile level in the backlog: unlike edge and patch it is not a geometry selection at all, so what it should do is an open question rather than missing work.
Zone painter patch editing: node/object model done, plus the frame and seam fixes The open multi-file defect turned out to be two frame bugs and is closed, and the node/object model change the plan called for is implemented. Rewrites the document around what is now true rather than what was planned: - Part 2 gains what the write targets actually STORE (a mapper record holds a delta, a PatchMesh slot a position), why the geom-changed callback carries a delta, why ObjectTM is not the display frame, why a zone rebuild must read the live zone rather than the display cage, and that a byte gate cannot see the display at all. - Part 3 is now the model rather than a plan for it: nodes, objects, and the three per-node facts that replaced the id-range test. - Part 4 lists the m35 gates against what each one proves. - Part 5 is the remaining backlog, with the sub-object levels unblocked, and records one open workflow question about how far seam propagation should reach by default.
Zone painter patch editing: state, invariants, and the node/object model plan Resume point for the patch-editing story. The first milestone is complete and gated; the next piece of work is a model change rather than a feature, and the open defect may dissolve under it. Part 2 is the part worth having written down: invariants that cost real time to establish and should not be re-derived. Overlays run after the GUI draw and must project by hand. Bound vertices are derived for ALL FOUR bind types, so the test is Binded and not the bind type - keying on the type shows nothing at all on real data. The geometry write target is not the tile carrier, and neither the mapper path nor the modifier-free path is an edge case (46 and 26 of 72 surveyed nodes). Geometry dirtiness cannot be seen by the RPO blob compare. Byte identity is measured against the null-edit output, never the source .max. Part 4 records the open multi-file defect with the evidence already gathered and the two hypotheses still standing, so the next pass starts where this one stopped rather than re-measuring. Part 5 is the model change: retire the primary/instance id range in favour of the usual objects and nodes, where several nodes may reference one object. The shape already exists in the tool for tiles - the paint carrier fans out by RPO pointer - it is only the zone list that does not use it.
