 # Current checkpoint — 18 October 2026
 
-The bundled game contains **5,463 reviewed HD pictures in 3,625 complete sequences**, including **4,338 Terrain pictures**. **290 originals still await approval**: 197 Terrain, 59 enemies and ground objects, 33 UI/other pictures and one boss. Held drafts and actual provider refusals are part of that remaining count.
+The included SourceF runtime now supports up to **256 explicitly listed Original detail cells**, with the quarter-painted-Source bound for lists above 64. The existing up-to-64 behavior and all cache identities through 128 remain unchanged. These are retained Original details, not generated HD. Raw PNGs, alpha, framing and asset eligibility are unchanged.
 
-This update adds 37 Terrain pictures across four separately reviewed scopes. The selected artwork uses untouched older PNGs, including the approved palette treatments; eight installed pictures now use the optional palette constraint. The `40365–40374` selection contains 14 explicitly static pictures and excludes `40372` and `40374`. No animation is split, and the earlier whole-group holds and the new `40374` provider refusal remain unchanged. Exact asset lists and qualifications are in the [HD completion ledger](hd-completion.json).
+The pack still contains **5,463 reviewed HD pictures in 3,625 complete sequences**, including **4,338 Terrain pictures**. **290 originals remain**: 197 Terrain, 59 enemies and ground objects, 33 UI/other and one boss. All 9,399 data files / 8,355,478,070 bytes, the eight palette opt-ins and the existing SourceE artwork/material/context authorities remain unchanged. No larger-detail trial is admitted by this runtime activation.
 
-The assembled data contains **9,399 files / 8,355,478,070 bytes**. Validation accepts all 5,463 HD frames with zero rejects and 45 mods with one override. Three 1920×1080 SDL controls completed successfully, and Root viewed each full image. Their PNG, RGB and alpha results matched the H5426 controls across 6,220,800 pixels, with zero measured changes. These controls do not establish visibility of all 37 additions or coverage of every optional policy. The finite scene and screenshot evidence does not establish every placement, seamless terrain or complete HD coverage.
+Focused production checks passed 113 Rust tests and 186 Python tests; 5 existing Rust tests were ignored. Full validation accepts all 5,463 frames with zero rejects, plus 45 mods with one override. Three 1920×1080 SDL controls completed successfully, and Root viewed all three full images. Their PNG, RGB and alpha results matched the SourceE H5463 controls across 6,220,800 pixels, with zero measured changes. These unchanged-art controls do not establish coverage or artwork approval for lists above 128 cells, every optional policy or all placements. The latest closed native Windows result is exact SourceE H5426 at 3f3107d6: 394 passed, 26 ignored and zero failed; no native Windows SourceF execution is claimed.
 
-The included Linux and Windows binaries remain at the validated SourceE runtime. The latest closed native Windows result is exact H5426 at `3f3107d6`: **394 passed, 26 ignored, zero failed**. That run also passed its HD, mod, Unicode relocation, `run.cmd` and audio checks. This new artwork revision has no claimed native Windows execution result yet. SourceF experiments remain private and unapplied.
+Iron Coast retains its published 14-mission retune and 45 current packages, including **Mission 2 version 1.0.2**. No mission schedules, scripts, prices or gameplay changed here; private pacing 1.0.3 is not part of this package. Earlier paid-route results and failed policies keep their recorded limits. See [Iron Coast retune evidence](iron-coast-retune.md). The 307 native AGX cinematic/font records remain preserved separately.
 
-Iron Coast retains the published 14-mission retune and the current 45-package resource set, including **Mission 2 version 1.0.2**. This artwork append changes no mission schedules, scripts, shop prices or gameplay. Earlier paid-route successes, failed policies and presentation checks retain their recorded scope; see [Iron Coast retune evidence](iron-coast-retune.md). The 307 original AGX cinematic/font records remain preserved separately.

-Current assembly, CLI, scene-review and SDL authorities are linked from [runtime release evidence](hd-runtime-release.json). Earlier SourceC, SourceE activation, artwork, HOLD and refusal records remain dated history. Validated package checkpoint; Git history records publication.
+Larger retained-detail lists still need independent whole-frame and genuine-context review, including coarse detail, palette cycling and neighboring join effects. Existing HOLDs and actual refusals remain in force. Current SourceF evidence and dated SourceE artwork records are separate in [runtime release evidence](hd-runtime-release.json). Validated package checkpoint; Git history records publication.
