Plans and draws flat field+monolith, repeating hills, road over cloud floor and pillar grid in a 3-strata fixture, binding passage/0-1 and 1-2 as fixed endpoints. Composed W1 probes: 3/4 seeds fail one passage interface, 4/4 fail the liminal walk audit near the mouths (support itself passes). Stopped per AGENTS.md. Same mouth-ownership failure class as FI (L133/L140) and VS seed 2 (L139).

# Linux144 — Core.Liminal.Field v1
|
||
|
||
| Variant (seed) | Arrival at eye height | Wide view |
|
||
|---|---|---|
|
||
| Flat field + monolith (0) |  |  |
|
||
| Repeating hills (1) |  |  |
|
||
| Road over cloud floor (2) |  |  |
|
||
| Pillar grid (3) |  |  |
|
||
|
||
**Result: stopped at the mouth-join gate; this is not ready to ship.** The new `Core.Liminal.Field` v1 recipe plans and draws all four seed-selected looks between fixed mouths. In the final composed probe, three of four seeds failed one of their two passage interfaces, and all four failed the liminal walk audit. The requested eight-seed-per-variant matrix was not run after the stop condition was reached.
|
||
|
||
## What changed
|
||
|
||
- Added one data-driven recipe, `Core.Liminal.Field` v1. `seed % 4` selects flat field with monolith, repeating hills, road over cloud floor, or pillar grid.
|
||
- The liminal plan binds the existing `passage/0-1/0` arrival and `passage/1-2/0` departure as fixed endpoints. It draws an 8-point route deck and structural supports; the road variant uses that deck as its route. The pillar variant resolved 221 grid pillars after route clearance.
|
||
- Added a three-strata fixture: Surface World → liminal → Tunnel Network. `BuildL144Fixtures.py` and `CaptureL144.py` reproduce the fixture and the eight captures.
|
||
|
||
## Composed probe
|
||
|
||
The final composed audit window was one run for each seed 0–3 at W1, using Clang 19 source stamp `8acbb7c3dfdb0484100d3d55036db20743ce76d74097b69362bb7d1a1c1d6302`. These are audit counts, not timing comparisons.
|
||
|
||
| Variant | Passage interfaces passed | Liminal walk audit | Passage shell / seam audit | Liminal negative control |
|
||
|---|---:|---|---|---|
|
||
| Flat field + monolith, seed 0 | 1/2 — FAIL | 222 blocked samples, 7 grade failures — FAIL | PASS | altered departure rejected — PASS |
|
||
| Repeating hills, seed 1 | 2/2; composed summary FAIL | 1 blocked sample — FAIL | PASS | altered departure rejected — PASS |
|
||
| Road over cloud floor, seed 2 | 1/2 — FAIL | 3 blocked samples — FAIL | FAIL, 1 floor violation | altered departure rejected — PASS |
|
||
| Pillar grid, seed 3 | 1/2 — FAIL | 289 blocked samples, 9 grade failures — FAIL | PASS | altered departure rejected — PASS |
|
||
|
||
The three partial passage-interface failures reached the requested stop threshold. Every liminal walk probe reported zero unsupported samples and zero structural-support failures; support alone therefore does not explain the blocked routes. The top Surface World route audit passed all four seeds. Passage naturalness and mouth-profile negative controls also detected their injected faults in all four logs.
|
||
|
||
## Captures and limits
|
||
|
||
All eight 1600×900 images passed `capture_quality.py`. Arrival cameras are 1.6 m above the fixed arrival mouth and look along the route. Capture exports used `--capture-skip-walkability` to preserve render evidence despite the failing composed audits; this flag was not used for the audit runs. The wide pillar view shows the overhead deck and one support rather than a legible field of grid columns, and the other images also expose the current route/deck defects.
|
||
|
||
No additional geometry change was attempted after the three-interface-failure threshold. Earlier diagnostics found the short terminal secant exaggerated the mouth grade; widening the tangent probe interval did not make the final composed walk pass. It remains unproven which combination of terminal connector geometry and nearby field solids accounts for the blocked capsule samples.
|
||
|
||
## Checks
|
||
|
||
- Clang 19 headless build completed; the final audit and capture executables report the source stamp above.
|
||
- Four composed probes ran at W1, one seed per variant. Planning/drawing and the per-audit results are in `Saved/Linux/l144/logs/probe8-seed00.log` through `probe8-seed03.log`.
|
||
- Eight capture quality checks passed. `git diff --check` passed.
|
||
- Not run after the stop gate: eight seeds per variant, GCC or W8/W12 determinism, owner canonical-hash comparison, fast tier, and one near-ready run. No performance timing window was collected.
|
||
|

Changed Unreal `Source/` files: none. Changed standalone sources include `StreamBenchmarkHeadless.cpp`, `StreamBenchmarkPipeline.h`, and `WorldAssemblyPrototype.h`.
