An all-tracks docs-vs-code audit (the same method that caught the storage
drift) found 23 confirmed inaccuracies where a doc's build-status claim no
longer matches the source — status markers that were never flipped after a
track landed, and a few paths left over from completed flag-days. All verified
against the code before editing; docs only, no behavior change.
The systemic ones:
- IOMMU enforcement (driver-model.md, drivers.md): docs said enforcement was
not built and "device_claim = ring 0" / "memory-safe is not true yet". It is
built (per-device VT-d/AMD-Vi domains programmed at device_claim, -ECONFINE
rollback, dma_alloc buffers bound and torn down at death; fail-open only with
no IOMMU). Restated; M16 marker flipped to done.
- The FHS flag-day paths: /etc/devices.csv -> /system/configuration/devices.csv
(devices-csv.md, new-driver-checklist.md, device-manager.md), /var/log ->
/system/logs (logging.md, new-driver-checklist.md), /mnt/usb -> /volumes/usb
(process-management.md). Following the old paths silently breaks driver match.
- protocol-namespace P4 "remaining" -> landed (only P5 remains); shared-fate
fan-out "not yet enforced" -> enforced; wall_clock "not built" -> built;
SMP affinity + fault-recovery "left" -> built; process_enumerate raw-pointer
trust model -> checked copyToUser/EFAULT; bounds.md maximum_devices static
hole -> dynamic per-registrar quota; init spawns fat -> volume-manager;
config "hardcoded, move to /etc" -> already CSV data files; vdso.md three-
value call; zig-self-hosting library/ layout; python argv "new" -> built.
Found and fixed by a multi-agent audit across 12 doc clusters, each finding
adversarially verified against the source.
Every binary's build.zig now names precisely the modules its source
imports (derived by scanning each artifact's sources, transitively
through same-directory files), and its zon carries only the domains
those come from — kernel stays implicit (the root shim + link script
live there). build-support's userBinary resolves each name through one
module-to-domain table (module_homes); Domains/domains()/defaultImports
and the raw recipe entry point are deleted. An undeclared @import is a
compile error (verified: injecting @import("xkeyboard-config") into
logger fails with 'no module named ... available within module
program'), and e.g. xkeyboard-config now appears in exactly two
manifests — the two keyboard drivers. Availability never bloated the
emitted binaries (Zig compiles only what a program imports); this makes
the declared interfaces honest. Production and -Dtest-case manifests
byte-identical; all build variants and standalone package builds
green.
The plan doc's status records completion (all waves + phase 3) and its
execution notes describe the finished shape; the fresh-session pointer
names build-support's userBinary instead of the deleted
addUserBinaryImpl, and the size-check carry-along note is discharged.
README gains the build/ directory in the layout tree and splits the
source-map row across root build.zig / build/images.zig /
build/qemu.zig. testing.md points at the distributed per-package test
steps; threading.md, threading-plan.md, driver-model.md, efi.md,
display.md, system-requirements.md, and devices-csv.md's adding-a-
driver checklist stop describing the pre-package build.
Review findings: the plan doc claimed no implementation existed, had the
domain dependency order wrong (kernel depends on protocol; device on
kernel + protocol + csv), never placed the three shared contracts, and
named a nonexistent new-driver-checklist.md. Its status now records the
implemented phases (and the deliberate pci-bus-first pilot), the target
shape carries the contract placements and the path-dependency-only
constraint on the kernel package's out-of-root abi export, and the
execution notes describe the post-pilot build for whichever session
runs the remaining waves. README's repo layout gains build-support/
and the packages-note; driver-model, threading, system-requirements,
and the two display plan docs stop citing root build.zig for recipe
facts that now live in build-support.
