Findings were going to docs/plan/level-assets.md and docs/formats/*.md while
roadmap.md kept listing work as open that has been done for some time. The worst
case was occlusion appearing twice: open at one line with "2 to 25 sectors, small
enough to read whole", and done further down with 412521 cells over 140939 masks.
The open line is deleted.
Also corrected:
- tfrag was listed flatly open while six tfrag entries beneath it were checked.
Now partial: format, topology, textures, LOD, normals and colour are done;
morph targets and strip/chain bookkeeping are not.
- sky was lumped in with volumes as open. Sky is done -- 149 sub-objects across 27
levels -- so it has its own entry, keeping the word at +0x0c documented as not
a count, since it disagrees with the table on most levels and reads 196617 on
level 2 against 4 sub-objects.
- level_overlay was open. It now has a parser and a 27/27 test, so it is partial
rather than done: header, constant block and level data parse, +0x10..+0x1220 is
identical on every level, and the word at +0x0c falls below the file length on 17
levels and above on 10. The header words are still unnamed and the Phase 3
seven-section parser is untouched.
- sound_bank was flatly open. It is partial: container framing parses and bounds
are verified on 27/27, but the SBlk record fields are not decoded and DAW shows
no stride, consistent with ADPCM.
- tie now records what is actually known, including the two indirection chains
that have not been walked: class table entries point into core_data.wad, and the
header's packets[0..3] resolve against the lump base. Level 0 has 74 tie, 238
moby and 7 shrub classes.
- collision now separates the header, which is decoded, from the cell layout,
which is not -- including the 17-entry table at +5932 against a 75-cell grid and
the disproved 64-byte RAM stride.
- moby_anim records the negative result: per-chunk-type record counts are
level-independent, so nothing in the chunk set is keyed by moby class.
The "Where we are" section now states plainly what has parsers and that what
remains open is naming rather than locating, and names the five types with no
decoded fields. Reading that list is how you would have known to ask.
Phase 2 remains in progress. Volumes and moby_anim have no located structure and
SBlk records, tie vertices and collision cells have located structure without
decoded fields.
