 The Rust Options screen includes **HD art**. It starts disabled. Enable it to use reviewed artwork from the selected data directory's `hd/hd.json`; each missing or rejected frame keeps the selected original / 2x / 3x / 4x crisp treatment. The bundled runtime uses `data/`, while development artwork and review jobs live under `../data/`. The scale setting still determines the indexed rendering resolution, and the HD toggle can be changed while paused. HD art is presentation only: simulation, collision sizes, banking positions and save content IDs stay unchanged.

Old material and physical reviews remain under their actual composition/current8ada measurement epochs, with historical case22 RGB-only aliases, old compile/constructor/schema stops and all per-ID grain/relief/native 1/core/contour qualifications preserved. The genuine mutual Terrain update uses six deduplicated Source vectors (four both-target and two 1052a support endpoints), 24 selected views and four true ordered pairs. Fixture independently reads all six context and four ordered pages/136 panes; zero new context holds. The Tank-versus-Turret update preserves 32 semantic rows with 17 fully clipped and 15 visible scene-scales, rendering only 15 baseline and 15 selected outputs. T1 independently reads all 15 whole triplets/45 native panes, with no new context hold. Those visible rows belong to four previously captured normal player death-transition scenes; no survival, natural timing, World or new material approval is claimed. Original Source shadows/cap 25 and foreign Turret field 11=0 remain literal. Original control reuse is backed by actual saved-body equality; no currentepoch/index upgrade is inferred from old RGB aliases. Both real typed positive physical gates are mandatory in contracts and before any plan projection save.

These have explicit native-art preservation policies: keep the classic cinematics and sharp original glyphs, validate complete playback/alignment, and never count them as generated HD replacements.

Old material and physical reviews remain under their actual composition/current8ada measurement epochs, with historical case22 RGB-only aliases, old compile/constructor/schema stops and all per-ID grain/relief/native 1/core/contour qualifications preserved. The genuine mutual Terrain update uses six deduplicated Source vectors (four both-target and two 1052a support endpoints), 24 selected views and four true ordered pairs. Fixture independently reads all six context and four ordered pages/136 panes; zero new context holds. The Tank-versus-Turret update preserves 32 semantic rows with 17 fully clipped and 15 visible scene-scales, rendering only 15 baseline and 15 selected outputs. T1 independently reads all 15 whole triplets/45 native panes, with no new context hold. Those visible rows belong to four previously captured normal player death-transition scenes; no survival, natural timing, World or new material approval is claimed. Original Source shadows/cap 25 and foreign Turret field 11=0 remain literal. Original control reuse is backed by actual saved-body equality; no currentepoch/index upgrade is inferred from old RGB aliases. Both real typed positive physical gates are mandatory in contracts and before any plan projection save.

 Canonical proof `6a1c897c80e7e07ab891ed69d451d5c0a1b6d1aa1029365756803a657da457ec` binds six real Root private writers, six different native CODE peers and six independent actual five-file final audits. One unchanged registrar dry run and one main call add four complete1 headers and two complete4 families; no family is split into singleton definitions. All 30 promoted files are exact audited bytes, including six untouched generated raws. Full 3,506 old header prefix remains exact. Terrain10525/1052a/206a0 preserve native 32/frame 0/origin 0 with crop/cue/coverage absent;20402 retains its present314,314,313,313 crop. Both enemy families retain their four present627 quadrant crops and absent cue/coverage fields. Old material and physical reviews remain under their actual composition/current8ada measurement epochs, with historical case22 RGB-only aliases, old compile/constructor/schema stops and all per-ID grain/relief/native 1/core/contour qualifications preserved. The genuine mutual Terrain update uses six deduplicated Source vectors (four both-target and two 1052a support endpoints), 24 selected views and four true ordered pairs. Fixture independently reads all six context and four ordered pages/136 panes; zero new context holds. The Tank-versus-Turret update preserves 32 semantic rows with 17 fully clipped and 15 visible scene-scales, rendering only 15 baseline and 15 selected outputs. T1 independently reads all 15 whole triplets/45 native panes, with no new context hold. Those visible rows belong to four previously captured normal player death-transition scenes; no survival, natural timing, World or new material approval is claimed. Original Source shadows/cap 25 and foreign Turret field 11=0 remain literal. Original control reuse is backed by actual saved-body equality; no currentepoch/index upgrade is inferred from old RGB aliases. Both real typed positive physical gates are mandatory in contracts and before any plan projection save.

+## 17 October 2026: actual5,340 coverage and explicit retained-Original10511 contacts
+
+Canonical registration `44fe6c5d5adccbc7b9eb9299a3d47539a7a12036af5580b29288d5738293f1e2` and immutable handoff `467c10e4c5eb943388e681cfceefb5e9f13650c1ffd31e25e137878098f36b28` add only10511. The canonical pair is hd.json `f965f89e1e131ede0c6debd6b5194948d4ae1d6f397fc6489a2f2bf4c418ac5d` / provenance `169142b153c1df2417db3c6fc3744d7d2be2f3211fc105163385f56e9fb356da`; all 5,339 earlier frame bindings and 3,512 complete headers remain exact. Native32/frame0/origin0/crop absence are preserved. The `original_detail_cells` field names exactly `(16,3)`, `(17,4)`, `(17,5)`, `(18,6)`: explicitly retained Original contacts, not newly generated artwork. The unchanged PNG is `d5a5d3f6e200ecb47b7f7326a316a4e4158caeaa36b68955b641f150fc68e7e7`; candidate `a16e57bbe6bb7fa4c33355418a37a325010603377f1ab75c6f1b51511251798c` and coordinator review `482281bd84e6fb95d2dbc385ada6d22e7abfe6cbc66ac1ff03678e85c10a5e38` bind the new native route. Iron3 actual final5 audit `5a8f593b0a6e60b20aa711d20fdac2603c1294814e0fd5712b060ad876acbdf7` and strict `5f29bd0b639a02d6d6c8eafe025fcf754ec9615a6a1cc9f31d7fd1bd393fe3d6` precede the one real registrar call. T1’s different material/function/context review `93c2235eb328393896d6e3e12263f98cbc6cd4ae1318176b1425d0a769fc1101` personally covers 27 complete pages/332 panes, including 22 genuine context keys/88 scale views. Coarser retained gray contacts, fine rippled water, stronger stone relief and visible Original/HD texture/value islands remain qualifications. Six genuine static endpoint triples preserve intact-versus-settled meaning; no new timing/World/Host claim is made. The plain generated-default10511 HOLD and unrelated held30097 remain unchanged.
+
+The actual handoff contains 2,874 pack files / 8,140,450,765 bytes and 1,370 proof files. Root intake `288d6f469d5d9488c7e5c48b07533e8105252a3c35456ddaf754fe7e922da352` and actual assembly `b0565489781004c83213a76b8680dbea3e3d82e375e062469fdb38dd8ffa5c62` bind **9,324 runtime files / 8,153,633,623 bytes**, preserving old data/Original/source18/binary bodies. Windows count-only metadata `3862d24291c302d647d8700b6d4dbc4295dda07556ef4a213fc419fedbca1d90` is not Windows execution. Root’s Q36 CLI validation, publication and this 5,340 pack’s own native Windows result remain pending; no validation result is inferred from assembly. The actual10511 native/current386e epoch is separately bound; old8ada and historical7b reviews retain their original epochs. This documentation update performs no renderer, decoder, intrinsic, registration or new art approval.
+
+Prior asset commit `1bc0a9ceff4800a7f85a0f7d98fb2cc983b23f41` is remote-confirmed (`b5b966b598a010fb124270ed6902dd4b599313e61751a9e9a314537288c4e38d`). Its exact native Windows run 39005816869 / job 117317961145 succeeded with 5,339 HD frames validated and zero rejects; observer `d47136ca63aec9214ee3eed6b363c3c4c169160e0cab6182ae54c8966590e499` / strict `e7f0ce22ca28ec399aa59ef27a156f386c822192aef8024377508480bdb1a42c`. The source-change commit `9015a6c9552ca2fafdb6c0582cdc40a41406d516` is a distinct pending native Windows observation (`74957407c75f7b9efe5a462e7e9966a652b39ec27797c153e0c02040bbb24004`, run 39006558412); the earlier success is not transferred to that source epoch. Earlier frozen observations and every other asset’s ledger/source/candidate/review binding remain unchanged.

+# Current checkpoint — 17 October 2026
+
+The self-contained game now includes **5,340 HD pictures / 3,513 sequences**,
+including **4,243 terrain pictures**. Its **9,324 data files / 8,153,633,623 bytes**
+pass complete manifest verification. Actual CLI validation passes all 5,340 frames
+with zero rejects and 45 mods/one override. Terrain `10511` is the new reviewed
+hybrid: four explicitly listed logical cells retain Original detail rather than
+claim generated HD detail. Previous 5,339 bindings remain exact.
+
+**413 original pictures remain:** 292 terrain, 79 enemies/ground objects,
+35 UI/other and seven bosses. The requested 97-picture batch is already published
+as `a45abc58`. Asset commit `1bc0a9ce` passed native Windows CI with 341 tests,
+zero failures and 26 ignored; the later `9015a6c9` runtime rebuild has its own CI.
+Receipts for this one-picture append are in
+`.reference/hd-root-next-publication-after5339/`; immutable intake is
+`handoff-5340-20261017`.
+
+Iron Coast retuning is active in `.reference/campaign-retune-20261017/`.
+The baseline covers all 27 original and 14 mod missions at all four difficulties.
+Mission waves, enemy movement, bosses and weapon presentation are being validated
+in a combined private mod overlay before application. The working mod packages
+have not yet been replaced. The 45-picture terrain context sample found visible
+road-material seams; affected artwork remains held for repair.
