nx_fixflywheel.nx -- THE HEREDITY RATCHET (bugforge-swe-scale, 2026-07-24). Evolution needs the genome to GROW across generations: every machine-verified green becomes teaching data for the next. This organ harvests verified (buggy->fixed) pairs and folds them into bf_fixcorpus ADDITIVELY, de-duped, so generation N+1 always inherits from a LARGER survivor pool than generation N. SOURCE = a MINED manifest (name|path rows) whose instances the maker resolved GREEN. For each row it reads the emitted candidate's header (// src=<origpath> op=<label>), recovers the buggy fn (the candidate's own mutant, under its real name) and the ORACLE fixed fn (the original at src), and appends `buggy TAB fixed` (multi-line via the 0x01 sentinel, matching nx_fixshot_lib). CONTRACT: only append a pair that fsl_shots would accept (fixed != buggy) AND that is not already present (exact-row de-dup) -- the ratchet is monotone + idempotent (re-run adds nothing new). This is the same additive+preload+dedup discipline the seq756 wipe taught (never REPLACE a live genome). verbs: harvest <manifest> <ledger> | selftest license_tier: ORIGINAL No hw writes (Rule 26).
