migration: 3 integer-brain kernels from idaptik straggler leaves (cluster C15) — corpus sweep complete

Closes the residual leaves the C13/C14 directory sweeps did not assign:
screens/{main,hub}, vm/wasm/src, devices/{types,common} — 8 .res files.

New brains (G1 compile, G2 parity all-pass vs independent JS oracle, G4 assail
clean): Logo (compass direction i%4), MainHubScreen (sidebar-nav dispatch),
DeviceTypes (device/security colour tables, distinct from the DeviceType
taxonomy brain). 217 parity cases.

CORPUS SWEEP COMPLETE. Across C13+C14+C15 this session: 315 .res files
classified, 32 new brains extracted (corpus 62 -> 94), 88 already-migrated,
195 documented NO_NEW_BRAINS (FFI shims, render-glue, float-domain cores,
string/JSON/wire cores, orchestration glue). Every non-test idaptik .res source
file is now accounted for. Capstone in EVIDENCE-C15-stragglers.adoc.

+// DeviceTypes -- the device/security colour-lookup co-processor, the pure-integer
+// core extracted from src/app/devices/types/DeviceTypes.res `getDeviceColor` and
+// `getSecurityColor`. The .res file is mostly type DEFINITIONS (the `deviceType`
+// and `securityLevel` variants, the `deviceInfo` record carrying name/ipAddress
+// STRINGS, and the `device` interface of unit->record closures); those stay
+// host-side. The two colour getters are the only computation, and both are pure
+// integer tables (an enum band in, a 24-bit packed RGB integer out) with no host
+// delegation -- exactly the AlertPalette shape.
+//
+// NOTE this is NOT the already-migrated DeviceType brain. That one captured the
+// shared/src 12-kind device TAXONOMY (Laptop/Desktop/Server/Router/Switch/... as
+// a 0..11 validity band). This brain captures the idaptik app-side 8-kind device
+// COLOUR table plus the 4-level security COLOUR table -- different variants,
+// different content, no overlap. Per the DESIGN-VISION the JS host keeps every
+// STRING (device name, IP) and every Pixi object; AffineScript owns only these
+// two integer tables, given an enum code returns the packed colour.

+
+*Outcome.* Every non-test idaptik `.res` source file is now accounted for as one
+of: a verified `Int(...)->Int` brain (corpus 62 -> *94*), a brain already
+extracted in an earlier cluster, or a documented `NO_NEW_BRAINS` host-side sense.
+The 195 `NO_NEW_BRAINS` files are FFI binding shims, PixiJS render-glue,
+float-domain cores (physics/geometry/animation), string/JSON/HTTP/wire-protocol
+cores, and orchestration/host-state glue — none of which admit a separable
+integer brain under the integer-only parity-harness ABI.
+
+*Method invariant.* Every brain is pure `Int(...)->Int`, no module state, floats
+carried as x1000 milli-units / permille where integer-exact (else host-side),
+guarded with `-1` out-of-band sentinels, authored in the flat early-`return N;`
+idiom, and gated three ways (compile -> differential parity vs an independent JS
+oracle -> assail). `total` is a reserved word and is avoided.
+
+*Not in scope.* This corpus is a demonstration + compiler-stress proof that lives
+in the affinescript repo. Wiring these wasm brains back into the running idaptik
+game (host bindings, replacing the `.res` consumers) is a separate downstream
+effort and is not part of this sweep.
