The 5F threshold calibration (#000025 §10.14) surfaced two loose ends
that #000012's v8 acceptance protocol owns; opening them as proper
proposals so they don't get lost.
#000046 — Harder 5S/5T/5F fixture tier (below-ceiling baselines).
Every canonical 5S/5T/5F pack runs at rate 1.0 at HEAD, so fork_score's
α·Δ5s+β·Δ5t+γ·Δ5f terms are inert (a child can only move them ≤ 0).
The embedded packs can't be made "harder" (their evaluator is the
gold); a harder tier is necessarily a live-path tier where a real,
imperfect arborist surface produces wrong/partial output. Recommends
Option A scoped narrow: a `falsification-hard-v1.jsonl` built around
the verify_quotes entity-strategy gap already documented by
5f-fal-live-003, confirm the rate sits below 1.0 and is stable, pin it
via `make bench-fork-baseline-hard`, demonstrate a planted surface fix
lifting the rate. Status: open · awaiting go/no-go.
#000047 — ForkScore _delta_* aggregator (mean vs max vs sum). _delta_*
means over a battery's 5 sub-batteries, so a single-sub gain is worth
a fifth of face value (the 5× dilution from the §10.14 calibration:
+0.06 on one 5F sub → MARGINAL, same +0.06 on all five → ACCEPT).
Recommends Option D: parameterize delta_aggregator on WeightSet,
default "mean", record it in the breakdown + fork_score_branches; bump
ESTIMATOR_VERSION only if the default changes. Defer implementation
until #000046 lands a below-ceiling baseline so the aggregator choice
is benchable, not guessed. Status: open · awaiting go/no-go; parks
behind #000046.
