Thank you, that was a strong first pass. Your scope warning about L76 was right and important. I need to correct my
|
||
brief: "about 75% of field time is the passage composer" was **wrong**.
|
||
- L76's term profiler covered only about 6.0M legacy samples for FI (5.6M for TN).
|
||
- L73 counts about 52M density calls per FI or TN whole view: 512 LOD0 tiles × 44,121, 448 LOD1 × 43,322, and so
|
||
on.
|
||
- The measured passage/support cost is about 6.5 of FI's ~40 field worker-seconds (~15%), not 75%. Roughly
|
||
30 worker-seconds of field time is not attributed to any term we've measured.
|
||
|
||
Your gain arithmetic for recommendation 1 inherited that error. Please redo it.
|
||
|
||
## Deeper pass (you now have more reasoning budget)
|
||
|
||
Examine **the whole generation chain**, end to end, for one cold whole view on the legacy FI/TN path. For each
|
||
stage, say what it does, how often it runs, what it costs per call (from code structure and the measured numbers),
|
||
and whether its work is necessary:
|
||
- world/plan resolution;
|
||
- tile key selection;
|
||
- `ClassifyBoxDetailed`;
|
||
- the dispatch into `AnalyticDensityAt` (and whatever runs for the ~46M calls the term profiler did not see);
|
||
- the composer;
|
||
- grid fill;
|
||
- MC;
|
||
- normals;
|
||
- skirts;
|
||
- ground/cap refinement;
|
||
- payload;
|
||
- Unreal publication.
|
||
|
||
The central question: **where do the unattributed ~30 worker-seconds most plausibly go?** For example:
|
||
- a different evaluation path the profiler doesn't instrument;
|
||
- per-call overhead outside the timed terms (dispatch, stratum lookup, virtual calls, allocation, cache misses);
|
||
- border/halo samples evaluated twice;
|
||
- normals sampling the field again;
|
||
- duplicated work between neighbouring tiles or LODs.
|
||
|
||
Give file:line for each. Then name the cheapest measurement that would confirm your top explanation, so the next
|
||
implementation round can verify it first.
|
||
|
||
Then **revise your ranked recommendations** in the light of the whole chain. Keep what still holds and drop what
|
||
doesn't. Add anything the chain review reveals.
|
||
|
||
Same rules as before:
|
||
- read-only;
|
||
- no edits anywhere, including temp files;
|
||
- web allowed;
|
||
- labels [CODE]/[MEASURED]/[PRIOR ART]/[INFERENCE].
|
||
- At most ~3,500 words.
|
||
- **Lead with the stage-by-stage cost map**, then the revised ranking.
