Phase 6 chose match targets by eye from the boundary inventory. tools/sf3_triage
now ranks every eligible candidate by (tier, size, address) from tracked inputs
alone and records why everything else was excluded.
Eligibility: an exact or fallthrough extent, a non-degenerate body, not already
registered, not the header entry, not named by --exclude. indirect, escape,
outside, runaway, contained and standalone are excluded and counted.
Tiers: 0 duplicate-group representative (one match, several addresses), 1 exact
leaf (no cross-references, so no symbol rows), 2 exact non-leaf, 3 fallthrough.
Result: 1916 listed (tier 0: 9, tier 1: 509, tier 2: 1394, tier 3: 4), with 252
degenerate bodies, 88 low-confidence grades, 12 registered, 1 header entry and
2 named near-misses excluded. The nine tier-0 entries are the real duplicate
groups: matching those nine bodies registers 22 function addresses.
The two deferred near-misses are excluded by name in the Makefile so the
exclusion stays visible rather than buried in the tool. 160 synthetic tests pass.
