The brief's rule is to commit reference data beside the finding so the
port can be built without a disc. Nothing had ever checked that the docs'
cited artifacts actually exist. doc_link_check.py walks every markdown
file under docs/, resolves each relative link, and reports targets that
are missing -- and separately targets that resolve to a ZERO-BYTE file,
which looks fine in any listing.
links resolving 1038 -> 1049
missing targets 16 -> 5
empty targets 0 -> 0
+11 resolving and -11 missing against 11 edits: the counts pair, which is
the confirmation the pass did what it claimed and touched nothing else.
Two of the sixteen were the evidence for the UI layout decode itself.
structures/ui-rat-layout.md is what the port is built on, and its two
figures -- backing "the tutorial PAUSE menu rebuilds pixel-accurately
from its sprites" and "the same method reproduces the main menu" -- were
written as captures/ui-layout/... from a file in structures/, one
directory too shallow. The headline evidence for the decode could not be
opened from its own document.
Eleven links had the wrong relative depth with the target present. Each
was rewritten only where exactly one candidate path resolved, so nothing
was guessed; the first pass left three alone because equivalent spellings
(captures/../captures/x) failed to collapse, and a second pass normalised
them.
Five remain genuinely absent and are left rather than invented: two point
at MEMORY.md outside the repo, one at a header in the separate
xenia-canary-native tree, and two name documents that were never written
(weapon-datasheet-runtime.md, canary-build-verified-env-confound.md).
None is port-relevant. A missing document is a different problem from a
bad path and is not something a link fix should paper over.
gworld.py's DEF_VTABLE 0x820AF844 and INST_VTABLE 0x820AF030 resolve exactly as
written: 13 unit definitions and 42 live instances, every one name-resolved, with
52 moving triples. The roster is coherent and stage-specific -- UN_S01_Asteroid_*
in the S01 training area, 2 e106 destroyers against 20 e007 turrets, 6 DeltaSaber_T
and exactly one _Player -- which is far stronger evidence than a hit count.
The constants were never stale. structures/unit-struct-runtime.md records its own
provenance ("all six tutorials and Stage 02 loaded from save slot 01") and
launch_mission.sh already encoded that route: title -> LOAD GAME -> slot 01 -> YES
-> READY ROOM -> TAKE OFF. LOAD GAME is the menu's SECOND item; the previous
iteration pressed the first (NEW GAME) and read the resulting 0/0 as evidence
about the constants. One `step down` separated a dozen iterations from this.
Control still owed and stated in the doc: the title-screen arm was measured in
earlier processes, not this one.
