Capability matrix

Per-subsystem, per-estimator view of what is real today and what is not. The badges are defined in Fidelity. Each row points at the backlog item that is expected to raise the badge.

Last reviewed: 2026-05-23.

Deployment note. The badges below reflect origin/main at revision 43d0db2 (post PR #42). The catch-up train (PR #38) brought the L1 subsystem rollout onto main after the 2026-05-23 baseline, so the live VM picks up the L1 surface on the next auto-update poll. The live MCP audit in docs/audit-2026-05-23.md §4 was conducted before the catch-up; §10 records the post-catch-up state.

Subsystems

Subsystem	Implementation	Estimator	Model card	Backlog
power	filtered (Li-ion + Peukert + thermal derate)	filtered (SoC + voltage Kalman)	subsystem, estimator	BL-003
apu	filtered (solar MPPT, methanol FC, vehicle, USB-C PD)	filtered (per-source Kalman)	subsystem, estimator	BL-005a
pmu / pdu	planned (lifts off PowerSubsystem)	planned	planned	BL-005b
thermal	filtered (two-state lumped: junction + enclosure, profile-driven)	filtered (per-channel Kalman with shrinking covariance)	estimator	BL-005, BL-028
compute	filtered (load fraction, profile-driven draw curve, thermal-throttle clip)	filtered (per-channel Kalman over load and draw)	planned	BL-007, BL-031a
storage	filtered (NAND wear, capacity accounting, write amplification)	filtered (per-channel Kalman over used and wear)	planned	BL-008
sensors	filtered (temp / humidity / baro; authoritative ambient source)	filtered (multi-channel Kalman with bounds validation)	planned	BL-009
position	filtered (lat / lon / alt dead-reckoning + GNSS fix gating + IMU drift)	parametric (v0.1 EKF passthrough with NaN/Inf validation; full constant-velocity EKF is BL-026)	estimator	BL-010, BL-026
biometrics	filtered (HR / core temp / hydration / cognitive load with physiological clamps)	filtered (multi-channel Kalman; physiology grounding is BL-040)	estimator	BL-011, BL-029, BL-040
comms	filtered (per-link envelopes drive FSM state.comms_state each tick)	parametric (per-link belief tracker; full transition particle filter is BL-030)	estimator	BL-012, BL-030, BL-048
inference	parametric (local-path with profile-derived latency / energy / capacity; cloud path deferred)	n/a	local mock	BL-013, BL-043
self model	planned (assess returns the engine's last_capabilities dict; layer wiring is BL-018)	n/a	planned	BL-018, BL-035

Cross-cutting surfaces

Surface	Status	Notes
audit (JSONL, output-hashed)	filtered	append-only with fsync + chmod 0600; redaction still flat (AUDIT-2026-05-23 C2). The live VM is currently audit-degraded (AUDIT-2026-05-23 N2).
policy + runner (tier-classified admission)	filtered	tiers consistent with ADR 0001 and 0013. Denial path still misses exit_code=1 (AUDIT-2026-05-23 M1).
OAuth issuer	filtered for single-client lockdown; planned for L3 multi-tenant	BL-019, BL-059. File-store lock and refresh-family revocation still open (AUDIT-2026-05-23 H6, H7).
anthropic client (daily cap + prompt cache)	filtered	Flush-before-unlock race closed (AUDIT C1); test coverage in tests/unit/test_anthropic_client.py. BL-021 surfacing still planned.
interop adapters (CoT, MISB, NMEA, STANAG, SensorThings, MQTT)	parametric	Encoders emit standards-shaped output with timestamp freshness checks; conformance is self-declared and uncertified (docs/conformance/).
scenario injectors	planned	The scenario YAML loads, but the v0.1 injectors do not yet mutate engine state. BL-014.
deterministic replay	planned	A SimClock with seed control would unlock replay; not yet scoped.

How to read this page

A row at filtered for both implementation and estimator means a controller can use the matching MCP tool with the covariance that the estimator advertises. A row at stub for either column means the output is not yet calibrated; the showcase suppresses covariance for those rows. Rows at planned are surfaces the architecture promises but the code does not yet provide.

The matrix is reviewed alongside docs/backlog.md. When a backlog item moves to [done], the corresponding row is updated and, where appropriate, the scenario gallery is regenerated to reflect the new substance level.
