+merged at `edb6fece332863a28cb402996143ff900ef33133`. This accepts an explicitly
+selected managed .NET 10 `PortalExample` inside a genuine `fs-gg-fable-game` workspace.
+The browser player, production server and default solution do not reference it;
+omitted/default selection excludes it. It is headless managed scene projection,
+not browser rendering or server-integrated physics.
+
+The released public Workspace Template `0.18.2` names producer `20c009bc` and uses
+canonical Game example source `49c7f5a`. A fresh independently acquired signed public
+archive has SHA256 `496aad0e89496719bc543edc6ffbf829a82307862e630ba4e174e374ac11cc4e`;
+all 480 payload entries match the original release except its feed signature.
+Direct default/opt-in generations matched outside Portal before build outputs.
+The separate installed public SDD `2.1.0` receiver invoked the unchanged public provider
+descriptor and actual public template, without a local-archive source override.
+
+Direct, retained and provider projects independently passed canonical payload checks,
+fresh public-only locked restore, the exact seven-package boundary declared above,
+Release build and actual default/presentation/invalid entrypoints 0/0/2. These execute
+the canonical five-tick traversal/pose/momentum/replay checks and twelve-frame
+presentation correctness. The committed lock remained `7769c72f` in all three cases.
+
+Retained adoption used a newly generated genuine public pre-Portal `0.18.1` workspace,
+not the earlier candidate receiver. Inventory/apply, safe removal and both recoveries
+preserved all 118 original files, 152 inventory rows, modes and three authored sentinels.
+The foreign in-folder sentinel survived; both journals ended rolled back and nine
+managed files were absent. Known new Portal build outputs remained. Separate ordinary
+`Server.Tests` discovered and passed 20/20 tests, with zero failures or skips and the
+original source, configuration, locks and sentinels preserved. New test outputs were
+recorded separately; whole-tree equality is not claimed. The first direct private
+snapshot failure is retained separately from its admitted fresh successful successor.
+
+This closes Box2D `.4` for the declared managed-template scope and P3's fresh/retained
+adoption contribution. Whole P3 remains Done: No. Existing raw performance smoke is
+still bound to `13a8cdeb` and its measured assembly; T4 supplied no new timing evidence
+or accepted budget. A genuine Portal-to-Portal version upgrade awaits a separately
+needed public successor. Global Wizard acceptance, browser physics/rendering, server
+authority and P4 remain separate. Original resume04/resume05 custody and effects were
+not reused, retried or accepted by these operations.
+
 A crate straddling an opening and colliding on both sides, or a rope/joint spanning
 areas, requires a separately designed and measured solver/constraint strategy. Body
 recreation does not preserve hidden contacts, warm-start state or exact solver rollback.

+qualifies `.4` for an explicitly selected managed .NET 10 `PortalExample` in the real
+`fs-gg-fable-game` workspace. Public Template `0.18.2`, producer `20c009bc`, copies
+canonical Game `49c7f5a` example bytes. Independent direct generation and the installed
+public SDD `2.1.0` provider both exercised the actual public template. Default generation
+excludes Portal; ordinary browser/server/default-solution behavior remains independent.
+
+Fresh public-only locked restore proved the declared seven-package rendering closure:
+Core, Physics.Box2D and Render `0.17.0`, UI Scene and KeyboardInput `0.31.0`, Box2D.NET
+`3.1.654`, and FSharp.Core `10.1.302`. Direct, retained and provider projects built in
+Release and passed actual 0/0/2 entrypoints, including canonical five-tick rotated
+transfer/replay and managed traversal-safe presentation. This rendering consumer does
+not change the adapter's independent four-package headless producer boundary.
+
+Adoption into a newly generated public pre-Portal `0.18.1` workspace, removal and both
+recoveries preserved all 118 original files, 152 rows, modes and three authored sentinels.
+A foreign Portal-folder sentinel survived; nine managed files were absent after recovery,
+with known new build outputs retained. Ordinary workspace tests then discovered/passed
+20/20, zero failures/skips, with original source/configuration/locks still preserved.
+Templates PR689 `5279f0d9` and required programme projection4369 `edb6fece` make that
+accepted evidence durable. No old retained receiver or interrupted native custody was used.
+
+This completes `.4` only for that headless managed-template contract. It does not close
+whole Portal P3 performance acceptance, qualify a later Portal-to-Portal version upgrade,
+activate the global Wizard, add browser physics or integrate the production server.
+Hidden-solver rollback and cross-platform determinism remain outside the original profile.
