config: drop the stale src/game/actors dead-reference baseline entry

[andrewboudreau]

A baselined reference that resolves is a pre-armed mask

check_dead_references has been printing this on every run against main:

1 baselined reference(s) now resolve -- run --update to shrink the baseline (not a failure)

The entry is:

{ "file": "notes/src-domain-buckets.md", "ref": "src/game/actors" }

It went stale when #1985 landed src/game/actors/WingFeather/, which made the path resolve. Produced by tools/check_dead_references.py --update, which removed exactly this one entry and added none — 133 → 132.

"Not a failure" is right today and wrong tomorrow. TU promotion is a mass path-deletion event — #2071 removed 23 per-symbol files in one commit — so if that directory is ever consolidated away, this entry absorbs the break silently instead of failing. That is the same class of hole as [two-green-prs-can-make-a-red-main], one step earlier in the chain.

Negative control

Measured, not argued. Removing WingFeather from both the index and disk (my first attempt moved it only on disk and nothing changed — the checker resolves via git ls-files, so an on-disk move is invisible to it), then running the checker under each baseline:

baseline	result	notes/src-domain-buckets.md → src/game/actors
entry present	FAIL: 3 prose reference(s) name a path that does not exist	masked
entry removed	FAIL: 4 prose reference(s) name a path that does not exist	names `src/game/actors`, which is not in the tree

diff of the two runs is exactly that one row. The removal is what restores the signal, and nothing else moves.

What I deliberately did not bundle

The other 3 rows in that control are pre-existing and unbaselined — they already fire. They are per-symbol paths in notes/actor-leaf-provenance.md:

src/game/actors/WingFeather/_ZN11WingFeather13InitResourcesEv.cpp
src/game/actors/WingFeather/_ZN11WingFeather8BehaviorEv.cpp
src/game/actors/WingFeather/_ZN11WingFeather6RenderEv.cpp

Doomed twice over: by promotion, and by the rename promotion requires — WingFeather is a coined name the cartridge contradicts.

_ZTV11WingFeather @ 0x021088a8 (ov002)   ROM name 11daFeather_c   DISAGREES

I measured the tree-wide scale before deciding whether to fix them here: 622 per-symbol path mentions across 90 prose files (notes/smartball-provenance.md 67, notes/bgobject-provenance.md 67, notes/actor-leaf-provenance.md 44, …). That is a real backlog and it is not a sed — each mention needs the reason written into the prose, or the next reader restores the path as a helpful clarification. It is filed separately rather than smuggled into a single-entry config change.

Gates

Base is eace12bd8 = current origin/main, and git merge-base --is-ancestor origin/main HEAD succeeds, so the merge tree is the branch tree — these are merge-tree measurements, not proxies:

check_dead_references            no new dead references, no broken links, warning GONE
pytest test_check_dead_references  29 passed
check_python_names               PASS

Both consumers of this file — .github/workflows/dead-references.yml and .github/workflows/tool-tests.yml — are covered by those two runs.

Config only. One file, four deleted lines, no src/, no tools/, no generated state.

Byte-verified means the range carries complete in a delinks.txt, so the ROM build compiled it and compared it to the cartridge. The 364 claimed functions have a src/ file named after the symbol with no NONMATCHING banner, and nothing compiles them -- dsd fills their addresses with the ROM's own bytes. Both together are the 11,217 this project calls matched.
