vasilito 22ba65ea07 LG Gram Round 2: build-blocker fixes + symmetric lid-switch wiring + docs
Three workstreams delivered in Round 2 (no build per operator
directive; verification deferred):

1. Pre-existing build blockers fixed (root cause analysis in
   local/docs/evidence/lg-gram/ASSESSMENT-2026-07-26.md):

   - relibc: edition-2024 unsafe-op-in-unsafe-fn in epoll::
     convert_event (commit dd2cd443 introduced unsafe fn with raw
     pointer derefs lacking unsafe blocks). Fix in submodule/relibc
     commit b80f8b47 wraps each deref in unsafe { } with SAFETY
     justification; outer unsafe fn signature preserved.

   - base: acpid Cargo.toml 'common' path bug. acpid lives at
     drivers/acpid/ (depth 2 in base workspace) but declared
     common = { path = "../../common" } (2 ..) which resolves to
     base/common/ — a path that has never existed. All 8 other
     depth-2 crates correctly use ../common. The build script's
     overlay-integrity auto-repair normally papers over this; it
     failed during Round 1 verification. Fix in submodule/base
     commit 28e356d5 makes acpid consistent with siblings.

2. Lid-switch symmetric wiring (submodule/base commit 887718da):

   Round 1 wired lid-closed → enter_s2idle() but missed the
   symmetric lid-open → exit_s2idle() counterpart. Without it,
   the system stays in 'wake devices armed' state when MWAIT
   never engaged. Round 2 makes the wiring symmetric. The
   userspace-driven wake path coexists with the kernel MWAIT-
   return path (kstop reason=2); the double-call is safe per
   ACPI 6.5 §3.5.3 (_WAK/_SST idempotent in working state).

3. Comprehensive stub sweep (no actionable findings):

   Extended the Round 1 sweep to cover all Red Bear original
   recipes and base fork non-driver crates. Zero unimplemented!()/
   todo!() macros in Red Bear original code. Remaining 'stubs' are
   either documented dead code (lookup_hid_quirks + HidQuirkFlags
   — 5-flag type defined, no consumer) or empty-by-design tables
   with real loader shape (PLATFORM_RULES, DMI_ACPI_QUIRK_RULES —
   documented in Round 1). No new stubs replaced.

Deferred to Round 3:

- acpi_irq1_skip_override kernel-side consumer (needs kernel
  SMBIOS scan + boot verification)
- LG Gram bare-metal boot validation (Phase 1, requires hardware
  + successful build)
- External-display detection for lid switch (Linux's
  HandleLidSwitchDocked=ignore)

The base fork submodule pointer in this commit was advanced by
a parallel agent session (b3fd5cc6 e1000d DMA barriers,
1331b8c0 rtl8168d DMA, 717bc436 ixgbed MSI-X) — those commits
are also tracked here. The relibc fork pointer advances to
b80f8b47 (my unsafe-block fix).
