feat(hardware): Emergency Boot Witness reference implementation
Add compiling Lean modules and Python shim for the Geometry Emergency Boot Witness specification (graphene supercapacitor geometric encoding). Lean modules (Semantics.Hardware.EmergencyBoot.*): - EmergencyBootTypes: HexCoord, CapClass, OpticalPath, VoltageDifferential, GrapheneMemristor, HybridOpticalPath, material properties - EmergencyBootState: PowerState, SolarPowerState, ScanState, seed assembly, emergency boot state machine with 6502 calculator efficiency targets - EmergencyBootShell: Command opcodes, status byte encoding, process definitions, executeCommand dispatch All use Q16_16 fixed-point arithmetic (no Float in compute paths). Verified theorems: utilizationWithinBounds, powerFailureMonotonic, commandOpcode_roundTrip. Python shim (4-Infrastructure/hardware/emergency_boot/): - EmergencyBootEngine simulating FPGA geometric scan and seed extraction - Demo CLI showing power failure → self-powered calculator mode → geometric scan → seed assembly flow Build: 3302 jobs, 0 errors (narrow target), 3313 jobs, 0 errors (Compiler) Generated with [Devin](https://cli.devin.ai/docs) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com>

by explicit premise `onHyperbolaApprox (forwardStep s Δu) Q16_16.epsilon` (line 69).
|
||||
Remaining: `TODO(lean-port)` discharge that premise from a formal `Q16_16.sqrt`
|
||||
error-bound lemma.
|
||||
- `SSMS.aciPreservedByMlgruStep`: explicit premise `hBlendACI` replaced by
|
||||
`h_aciBound_nonneg : H.aciBound.toInt ≥ 0` (line 549). The `f_eps` and
|
||||
`omf_eps` sub-lemmas are proved with `omega` (lines 627–641). The `t1` proof
|
||||
(line 600) uses `mul_mono_left` with the correct hypothesis chain. The `t2`
|
||||
proof (line 617) corrected to pass `Q16_16.abs (cT i - cT j)` as the first
|
||||
arg to `mul_mono_left`. Critical remaining blocker: `Q16_16.abs_triangle` is
|
||||
admitted (FixedPoint.lean:674); the `bound` calc uses it and is effectively
|
||||
admitted. Once `abs_triangle` is proved, `aciPreservedByMlgruStep` closes.
|
||||
- `SSMS.aciPreservedByMlgruStep`: theorem signature updated with
|
||||
`h_ft_range : ∀ i, (fT i).toInt ≥ 0 ∧ (fT i).toInt ≤ FixedPoint.q16Scale`
|
||||
(line 546). The `hprev` and `hcand` sub-proofs use `abs_sub_comm` with correct
|
||||
argument ordering (lines 559–571). The `f_eps` and `omf_eps` sub-lemmas are
|
||||
proved via `mul_mono_left` + `one_mul` (PROVED, lines 605–607, 611–614).
|
||||
The `omf_toInt` equality is proved via `q16Clamp_id_of_inRange` (lines 575–599).
|
||||
The remaining `admit` (line 619) is the full mlgruStep preservation chain:
|
||||
triangle inequality + mul bounds → H.aciBound. Requires `abs_triangle` and
|
||||
`abs_mul_le` to be proved in FixedPoint.lean.
|
||||
- `FixedPoint.lean` Q16_16 lemma library (lines 617–695):
|
||||
- `mul_mono_left/right` ✅ PROVED — `Int.ediv_le_ediv hpos hmul` pattern works
|
||||
with explicit `hpos : 0 < q16Scale` proof
|
||||
- `abs_sub_comm` ✅ PROVED — three-case split on `d := a.val - b.val` relative to
|
||||
`q16MinRaw`/`q16MaxRaw` bounds
|
||||
- `sub_eq_add_neg` (line 620): admit, unused
|
||||
- `add_le_add` (line 652): admit, unused
|
||||
- `abs_nonneg` (line 659): admit, unused
|
||||
- `abs_mul_le` (line 665): admit, unused
|
||||
- `abs_triangle` (line 674): admit, used in SSMS `bound` — the `q16Clamp`
|
||||
internal `Int.abs` makes sign analysis non-trivial; needs case split on sign
|
||||
of `(a.toInt * b.toInt) / q16Scale`
|
||||
- `abs_triangle` (line 674): admit, needed for SSMS preservation chain
|
||||
- `EmergencyBootTypes.lean` — 6502 design philosophy hardware types (graphene memristor,
|
||||
optical fiber hot/cold paths, voltage differential computation). All structures compile;
|
||||
remaining formal work: `eigensolid_convergence` for optical delay-line memory,
|
||||
`receipt_invertible` for geometric seed extraction.
|
||||
- `EmergencyBootState.lean` — power failure detection, seed assembly, self-sufficiency
|
||||
checks. Verified: `utilizationWithinBounds` (FPGA resource limits), `powerFailureMonotonic`
|
||||
(bridge isolation implies no false detection).
|
||||
- `EmergencyBootShell.lean` — Tiny IP command interface (BOOT, SCAN, STATUS, EXIT, etc.).
|
||||
Verified: `commandOpcode_roundTrip` (opcode parsing correctness).
|
||||
TODO(lean-port): status byte round-trip theorem, phase-disjointness for command gating.

|
||||
Python I/O shim for the Geometry Emergency Boot Witness.
|
||||
Simulates the FPGA-based geometric scan, seed extraction, and
|
||||
emergency shell interface.
|
||||
|
||||
Per Research Stack contract:
|
||||
- Lean owns all decisions (admissibility, gating, classification)
|
||||
- Python owns I/O (read JSON, write JSONL, call subprocess, format output)
|
||||
- This shim calls Lean via lake exe for decision logic and formats/stores results.
