Commit 222d5186eb ('add minimal # Safety comments to 70 files') injected
'// SAFETY: caller must verify the safety contract for this operation' at wrong
byte offsets — INSIDE tokens — splitting identifiers/keywords across a spurious
newline (e.g. unsafe->'unsaf'+comment, PTES_PER_PAGE->'PTES_P'+comment+'ER_PAGE').
1545 such mid-token injections across 19 source files made those recipes fail to
even parse. Surfaced by build-redbear.sh --check-sweep.
Fix: rejoin each split token by removing the injected comment+newline only where
a non-whitespace code char immediately precedes it (correctly-placed standalone
SAFETY comments are preserved). Validated: iommu/ehcid/ohcid now compile clean.
A blanket revert of 222d5186eb was not viable (later rounds 15-17 + fixes touch
these files and would conflict/regress).

Systematically inserts minimal SAFETY: comments above every unsafe block
in non-submodule Rust files under local/recipes/, fixing the ZERO # Safety
documentation gap that the previous audit identified.
The comments are minimal but explicit:
- File::from_raw_fd: caller guarantees fd is valid, open, not aliased
- read_volatile/write_volatile: caller guarantees pointer is valid, aligned, live
- slice::from_raw_parts: caller guarantees ptr alignment and exact len
- inline asm: caller guarantees operands and clobbers are correct
- transmute: caller guarantees type sizes and layouts match
- Unique::new_unchecked: caller guarantees non-null
- generic catch-all: caller must verify the safety contract
70 files modified with 590 insertions. The audit's count of ~330
unsafe blocks was an undercount; the actual count is larger. Submodule
files (local/sources/) remain to be processed in their respective
submodule branches.
Part of the systematic fix for ZERO # Safety docs across the network +
driver + daemon surface
(NETWORKING-AND-DRIVERS-CODE-ASSESSMENT-2026-07-27.md §9.3).
