Agent Ensemble — Function Inventory

Reference catalog. Session-start spec lives in BOOT.md (mandatory reads, Knowledge Activation triggers, model policy). Read BOOT.md when starting a session; read this file when deciding which specialist to wake for a specific task.

Ensemble size: 6 specialists, all at .claude/agents/<name>.md. Each card declares its own tools, model, and scope.

abi-membrane-warden (Sonnet)

Guards docs/abi.md's contract on the Rust side: the ABI stays small, bulk-only, version-disciplined, string-free, callback-free, and never degrades into JNI-shaped one-crossing-per-element calls. First gate on any new lgj_* symbol.

simd-savant (Sonnet)

Holds the "all Rust SIMD comes from ndarray::simd::*, never ndarray::hpc::* or raw intrinsics" invariant for native/lgj-abi. Adapted from lance-graph's own card of the same name, scoped to this repo's one consumer file (kernels.rs).

handle-lifecycle-auditor (Opus)

Adversarially falsifies the generation-checked handle registry's safety claims — use-after-close, double-close, fabricated handles, parent-closed propagation — rather than trusting the design doc. The one agent whose job is actively trying to break the ownership story.

java-surface-warden (Sonnet)

Enforces the "zero FFM types, zero native-address-shaped values, zero per-row object materialization" rule on the public Java API, and checks that the fluent View/Mask surface stays lazy and reads as familiar, generatable-looking Java — the accessibility half of the mission thesis.

panama-bridge-engineer (Sonnet)

Owns correctness of internal/ffm: MemoryLayout definitions matching docs/abi.md byte-for-byte, downcall handles resolved once and cached, the manifest cross-check at load time, Arena/segment lifetime nesting.

valhalla-lab-scientist (Opus)

Enforces the three-truths method and measurement-before-claim discipline on everything in valhalla-lab/ and bench/. Rejects any performance or representation claim that isn't backed by a reproducible number, and specifically checks that the mandatory N-objects vs N-values vs 1-lane experiment is present and honestly reported.

See BOOT.md for the Knowledge Activation trigger table (which agent wakes for which file path) and the model-policy rationale.
