loadOverlayPatches already throws on a missing file (the caller named
it, so absence is a misconfiguration) — the existsSync guard was a
second fail-loud mechanism for the same miss with a prettier message.
The loader's throw keeps the fail-loud contract the Windows-default
note records.
The launcher's healProfilesModuleFallback BFS-links the apps/cli dependency closure into the profile's node_modules (the pwsh-local precedent): without dsh-pwsh-sandbox in apps/cli dependencies, a fresh Windows host cannot resolve the inserted row. Assert the closure reaches both inserted packages in the real-layers composition; rewrap the windows-shell layer comment.
The Windows platform layer re-enables the base fs-sandbox row (removing its disable), but still inserted dsh-fs-local: both extend FileSystem and provide ctx.fs, so every shipped win32 profile failed at load. Delete the insert; fs-sandbox stays the single fs provider exactly as on POSIX. Sync the roster specs, the base/reference README pairs, the sandbox core doc (read-only grants no sink on Windows), the windows-shell JSDoc, and re-record the i18n pairings.
The resolver suite previously exercised only fixture patch lists, leaving
the real shipped windows.cordis.patch.yml and the bundle→windows→user
composition ordering untested on Linux CI. The new cases load a temp
profile whose bundle layers resolve from the real dsh-base/dsh-web-app
packages (app installation anchor), apply the platform layer through the
boot's own composeEntries algorithm with the platform injected, and
assert the win32 danger-full-access roster (eight disables, three
inserts, no warnings on the web profile). A second case pins POSIX
unchanged and the base-only-profile ui-permission no-match warning as
warned-but-harmless, matching the patch header's documented contract.
win32 hosts booting a shipped profile now get pwsh-local as the ctx.bash
executor and tool-pwsh as the shell tool through the base bundle's new
windows.cordis.patch.yml platform layer, injected by the launcher between
the bundle layers and the user layers on win32. bash-sandbox, tool-bash,
permission, and ui-permission are disabled there: the POSIX-only executor
cannot run on Windows, and dsh-permission requires a confining executor.
Overriding the default is a composition decision through the user's
cordis.patch.yml; there is no environment override channel.
apps/cli and dsh-base re-declare dsh-pwsh-local/dsh-tool-pwsh so the
profile module fallback links them for cold starts (the profiles rework
had dropped them from the CLI closure).
Promotes the windows-pwsh-default Agent Note from proposed to implemented
and documents the platform layer in the base bundle README.
