…egy decision

## Why

The original FALSIFY-QW3-MOE-FORWARD-004 test description references
`llama-cli ... --verbose --logit-output` as the reference path for
full-vector logit dump. **That flag does not exist** in stock
llama.cpp v7746 (`llama-cli --help` exposes `--logit-bias` but no
logit-output flag).

M32d cannot proceed without picking an actually-existing reference
path. This amendment records the decision so downstream M32d.1-.4
sub-slices have a stable target.

## Decision

PRIMARY (full-vector cosine > 0.99): HF transformers FP16 via uv-run
Python — `uv run --with torch --with transformers
scripts/generate_qwen3_moe_fp16_logits.py`. Dumps the full
151936-dim logit vector at position 0 to a JSON fixture.

SECONDARY (top-1 argmax sanity): llama.cpp via subprocess — runs
`llama-cli -m <gguf> -p ... -n 1 --top-k 1 --temp 0.0 --seed 0`
and parses stdout to extract the single emitted token; asserts
apr's argmax == llama.cpp's top-1.

REJECTED: patched llama.cpp full-vector logit dump (out-of-tree
patch maintenance burden too high for the discharge value).

## What ships

1. `metadata.amendment_history` v1.3.0 entry recording the three
   reference paths considered, the decision, the rationale, and
   the M32d sub-slice plan (.0–.4).

2. Top-level `version` 1.2.0 → 1.3.0; status comment expanded to
   note the v1.3.0 strategy decision and the missing llama-cli flag.

3. `implementation_stages` M32d entry rewritten to enumerate
   M32d.0–M32d.4 sub-slices with concrete deliverables per slice.

4. `falsification_tests` FALSIFY-QW3-MOE-FORWARD-004 rewritten:
   - `prediction:` two-axis (cosine vs HF FP16 + argmax vs llama.cpp)
   - `test:` references new fixture path + subprocess invocation
   - `if_fails:` 3-step diagnostic order keyed off which axis fails

5. `cross_repo_references[paiml/claude-code-parity-apr].current_version`
   bumped 1.19.0 → 1.20.0 (companion repo bumped this morning at
   PR #38 squash 5aff6d5).

## What's NOT in this PR

- The fixture-generation script (M32d.1, next slice).
- The parity tests themselves (M32d.2, M32d.3).
- The DRAFT → ACTIVE_RUNTIME flip (M32d.4).

## Test plan

- [x] `pv validate contracts/qwen3-moe-forward-v1.yaml` — 0 errors, 0 warnings
- [ ] CI ci/gate green
- [ ] Workspace test green
