Entry \disabled\ interpolation makes the launcher's separate platform layer
unnecessary: the base bundle's cordis.patch.yml now gates both shell stacks
on its own rows — bash-sandbox/tool-bash disable on win32, and their twins
pwsh-sandbox/tool-pwsh mount only there with the inverted expression — so
exactly one shell stack mounts per host from one shared patch file.
windows.cordis.patch.yml and the launcher's windows-shell.ts injection (boot,
live recomposition, config dumps) are deleted, with the workspace-constraints
entry and the dsh-base exports/files entries following. The windows-shell spec
pins the effective per-platform roster through the real bundle layers, and
base.spec pins the four symmetric gates. The superseded active notes are
updated and cross-linked; the loader note records the fold itself.
The Windows platform layer disables tool-bash and inserts the pwsh stack, but the shipped presets each mount a tool-bash row that re-enabled the tool on win32 — the session had both a PowerShell-backed bash tool and tool-pwsh, silently, because no spec pinned the composed preset layer.
The Loader now evaluates a disabled: !!js expression against the loader context at every mount decision; disabled is the only interpolated metadata field, and the raw node stays in the options so write-back keeps the !!js form. The standard/code/cordis presets gate tool-bash with process.platform === 'win32', verify-cordis-config allows expressions in disabled only, and the windows-shell spec pins the preset-level invariant.
