S271: Wave 44 — expand announced methods to cover science + inference

ANNOUNCED_METHODS expanded from 33 compute-only to 47 methods spanning
compute.*, science.*, and inference.* namespaces. All 14 science/inference
semantic impl names wired in dispatch_by_impl_name to existing compute
handlers. Wire L3 cost estimates added. Capabilities claim now matches
announced method surface (Wave 44 P2 fix).

88 JSON-RPC methods, 9,126 lib tests, 0 clippy warnings.

-**Date**: May 2026 — S270
+**Date**: May 2026 — S271
 **Philosophy**: Math is universal, precision is silicon. Workarounds are
 short-term solutions that increase debt. We aim to solve deep debt over
 iterations, evolving toward vendor-agnostic, capability-based solutions—
 with production stubs surfacing typed configuration errors and capability
 guidance, and auth policy driven by explicit environment configuration
 where applicable.

 **Post-budding, dependency-sovereign, IPC-first, fully concurrent, capability-based.** barraCuda is a separate primal at `ecoPrimals/barraCuda/`. ToadStool is the hardware infrastructure layer — GPU/NPU/CPU discovery, capability probing, workload orchestration, and shader dispatch.

+- **23,000+ tests** (9,126+ lib-only), 0 failures, 0 clippy warnings, 0 fmt diffs. Full workspace concurrent test suite.
 - **87 JSON-RPC methods** (direct) + semantic registry. Wire Standard L3 (partial): `cost_estimates`, `operation_dependencies`. **Recommended caller timeout: ≥3 seconds** for health probes during startup.
 - **Phase C complete** (S245–S253) — toadstool-cylinder (153 .rs, 520 tests), DRM/MMIO/AMD/NVIDIA/VFIO hardware modules absorbed from `coral-driver`. `OwnedFd` VFIO fd ownership (S253). SwapOrchestrator real quiesce/persist/restore (S253). `toadstool device` CLI with swap/list/status/warm subcommands (S253). GspBridge trait boundary.
 - **Phase D: Sovereign dispatch validated** (S250–S263) — `try_local_dispatch()` via `ComputeDevice` trait before `coral_client` IPC forward. Full buffer lifecycle. AMD DRM dispatch live. **NV VFIO e2e dispatch validated on Titan V** (S263): warm handoff → VFIO open → channel → DMA roundtrip → GR init. Current frontier: FECS PENDING_CTX_RELOAD.
 - **Stale socket hygiene** (S264) — CLI daemon SIGTERM + socket cleanup. Display IPC Drop impl. UDS unlink-before-bind audited.
 - **sporePrint Wave 28** (S265) — `sporeprint/validation-summary.md` + CI dispatch to sporePrint.
 - **Neural API primal.announce wiring** (S270) — `primal.announce` wired into JSON-RPC dispatch, startup self-announcement to biomeOS Neural API with capabilities (compute, science, inference), cost hints, latency estimates, signal tier (node). 88 JSON-RPC methods.
 - **Sandbox working_dir production** (S269) — `data_dependencies` pre-dispatch validation with BLAKE3 integrity. `SandboxSpec.working_directory` wired into sandbox manager. 90+ upstream clippy errors absorbed.
-- **Deep Debt** (S240–S270) — All Duration literals extracted to named constants. `CORALREEF_*` env vars deprecated with `TOADSTOOL_*` primaries + deprecation warnings (S253). Zero `#[allow(deprecated)]` remaining. All lint attrs have `reason`. Zero production mocks/TODO/FIXME/unreachable!(). All unsafe SAFETY-documented. `cargo deny check bans` passes clean.
