Release notes: 2026-05-25 — tier1-num-fft-harnesses-wp1¶

Status: Ready for review
Repo: li-langverse/lic
PR: (feat/bench-fill-wp1-num)
PH / REQ: PH-5b, PH-7e
Author: agent

Summary (one sentence)¶

Adds tier-1 micro harness directories for all catalog num_* benchmarks plus fft_1d_fixed, each with params.toml, shared-C oracle, Li driver, and bench.py registration.

Agent continuation (required)¶

Read: benchmarks/tier1_micro/<id>/, benchmarks/harness/bench.py (_WP1_NUM_IDS), ../benchmarks/catalog.toml num rows.
Run: python3 benchmarks/harness/bench.py --tier 1 --verify-results --only num_cg (or full WP1 list); merge after CI green.
Then: benchmarks WP5 sync-paths-from-lic-tree.py to set catalog path fields; WP7 full bench run.
Blocked on: none

Changed (specific)¶

Area	What	Evidence
Harness dirs	17 new `benchmarks/tier1_micro/<id>/` (16× `num_*` + `fft_1d_fixed`)	`scripts/gen_wp1_tier1_num_harnesses.py`
Harness	`TIER1_BENCHES` extended via `_wp1_num_bench_specs()`	`bench.py --verify-results` 17/17 ok
Registry	`implemented_smoke: true` for catalog `num_*` in algo_registry	`benchmarks/competitive/algo_registry.json`

Not changed (scope fence)¶

Tier-2 physics / CFD / FEA / QM harnesses (WP2–WP4) — not in this PR
benchmarks catalog path column sync — WP5 in benchmarks repo
Full latest.csv measurement sweep — WP7
Pure-Li numerics implementations (smoke uses shared C oracle via LI_EXTRA_C)

Breaking changes¶

None

Security¶

N/A — smoke microbench kernels only; no trusted surface change.

Performance¶

N/A — harness scaffolding; ratios documented after WP7 ingest (dashboard).

Downstream¶

Repo	Action
benchmarks	WP5 path sync + WP7 ingest after lic merge
lip / lit / lis	N/A

CHANGELOG entry (paste into Unreleased)¶

### Added
- Tier-1 micro harnesses for catalog `num_*` + `fft_1d_fixed` (PH-5b) — `benchmarks/tier1_micro/`, `bench.py` registration
