osint/fma: heart anatomy /fma cockpit view — 8:8 [container:identity] HHTL tiers

[AdaWorldAPI]

What

Adds the FMA heart anatomy slice as the /fma route of the existing OSINT cockpit — same app as /osint, reusing decodeSoa, the OSO1 wire format, and the cockpit/public/*.soa serving path (no cockpit-server change; Railway re-embeds dist/). The slice is a heart organ → chamber → wall → tissue → cell partonomy plus six cross-cutting global tissue TYPEs at the ceiling pole, baked by osint-bake's fma binary.

The addressing — 8:8 [container:identity] HHTL tiers

Each HHTL tier is one u16 = [container : identity] = [mixin-node : instance-on-it] = 256 × 256 = 64k deterministic per tier. The high byte names the KIND mixin node (Organ/Chamber/Wall/Tissue/Cell — the family things attach on), the low byte the instance:

HEEL [Organ:Heart]  HIP [Chamber:LV]  TWIG [Wall:myo]  LEAF [Tissue:muscle]  family [Cell:B]

The non-zero tiers ARE the partonomy path, so the address says where a node sits — no edge lookup, no Morton decode. The cockpit lays out straight from the tiers (tierPos: y = depth, x = nested slot under the parent instance), so the HHTL block is load-bearing rather than write-only ornamentation.

The first commit (7455c4e7) tried a Z-order Morton path crammed into the single identity field; the second (a8603516) replaces it with the tier model above — kept as two commits to record the correction.

OGAR PR quarto-dev#116 alignment

This is the Cascade (ontology) reading of OGAR's [container:member] FMA tier model; OGAR's ogar-fma-skeleton is the Located (spatial) sibling (the same 8:8 tiers carry coronal x:y / depth-z Morton cells). Mirrors OGAR's [bodypart:bone] LeafTile, uses classid 0x0A01 (ConceptDomain::Anatomy), and supersedes the 12+4 EdgeBlock with family-node grouping (the container byte = the mixin/family node).

Verification

• Byte contract checked end-to-end: the cockpit's read offsets match the Rust-written GUID byte-for-byte across organ→chamber→wall→tissue→cell; ceiling sentinel ([ff:ff]) intact.
• Bake deterministic (95 nodes, 112 edges, 5176-byte asset); cockpit tsc clean.
• Browser render not exercised in this environment.

Summary by CodeRabbit

• New Features

  • FMA graph visualization now uses fixed tier-based positioning for more predictable and stable layouts, replacing physics-based simulation.

• Improvements

  • Graph rendering performance enhanced with automatic view fitting and eliminated stabilization delays.
  • Node sizing and visual styling adjusted to align with the new positioning model.

📝 Walkthrough

Walkthrough

Refactors FMA node addressing from a basin-local model to an 8:8 [container:identity] Cascade HHTL tier scheme. The Rust bake binary encodes tier GUIDs; the TypeScript SOA decoder gains per-node tier arrays (identity, heel, hip, twig, leaf, family); FmaGraph replaces force simulation with deterministic fixed positions derived from those tier values.

Changes

Cascade Tier Model: Encoding → Decoding → Fixed Layout

Layer / File(s)	Summary
Cascade tier encoding in fma.rs crates/osint-bake/src/bin/fma.rs	Changes CLASSID_FMA to 0x0000_0A01, adds MX_* mixin constants and a tier() packing helper, rewrites part_of_node to build GUIDs from HEEL/HIP/TWIG/LEAF/family tier pairs, updates build_heart() to iterate u8 instance ids per tier without basin values, and reformats the main() part-of-address output to [xx:yy] notation.
Soa interface and decodeSoa() tier arrays cockpit/src/OsintGraph.tsx	Extends Soa with identity, heel, hip, twig, leaf, and family Uint16Array fields; allocates and fills them per-node in decodeSoa() alongside the existing ceiling sentinel check; includes the new arrays in the return object.
FmaGraph fixed-position layout cockpit/src/FmaGraph.tsx	Adds layout constants (COL, ROW, POLE_Y), an inst() helper, and tierPos() mapping SOA tier bytes to deterministic (x, y) coordinates; disables vis-network physics; pins each node with fixed: {x, y}; places ceiling nodes as diamonds in a pole row ordered by index; replaces stabilizationIterationsDone callback with afterDrawing → fit({ animation: false }).

Poem

🐇 Hop, hop through the tiers we go,
Eight bits wide and eight bits deep,
No more physics making nodes creep—
Fixed in place like organs should be,
HEEL and HIP and TWIG, you see!
The cascade slots each chamber right,
A diamond heart glows in the light. 💎
