Repair the two defects that made the VFS rootfs/shell input sidecars
nonpublishable: an invalid fork_instrumentation="auto" and local-only
file:// bottle urls.
- scripts/homebrew-generate-sidecars-from-env.sh: package_fork_instrumentation()
now emits only the sidecar schema enum (not-required/required/disabled/
unknown), aggregated from per-output package.toml policies; the legacy
"auto" placeholder and any unknown value can no longer reach a sidecar.
- packages/registry/{16 scoped}/package.toml: declare fork_instrumentation on
each output (bash/dash/git/vim required; the rest not-required), matching
whether build-<name>.sh applies wasm-fork-instrument to a forking binary.
- docs/homebrew-publishing.md: document the fork_instrumentation disposition
values and the publishable https bottle-url requirement.
- test-runs/kd-0hns: regenerated sidecars with corrected fork disposition and
canonical GHCR https urls. Combined 12-package rootfs/shell tap validates:
`xtask homebrew-validate` -> packages=12 bottles=12 ok. Disposition and
passed/failed/skipped outcome lists cover all 16 scoped packages.
Publishable (12/16): dash, git, vim, less, lsof, modeset, nano, netcat, wget,
fbdoom (repaired) + bzip2, xz (adopted pilot). Blocked (4/16, missing Homebrew
Formula): bash, ncurses, curl, nethack.

…r.5) Run wasm32 in-browser smokes (Chromium/Playwright via BrowserKernel) for the 12 kd-0hns rootfs/shell packages and record the results in their Homebrew sidecars. Certified browser_compatible=true (10): dash, git, vim, less, lsof, nano, netcat, wget, bzip2, xz -- each boots in-browser and passes a package smoke (exit 0 + expected output). Sidecars regenerated via `cargo xtask homebrew-sidecars` so provenance shas stay consistent; `homebrew-validate: ok`. Skipped with reason_code (2): modeset (framebuffer-device-required, /dev/dri), fbdoom (framebuffer-and-iwad-required, /dev/fb0) -- framebuffer/device programs not certifiable via the non-interactive terminal smoke, mirroring the Node framebuffer skips. Encoded as browserFormulaUnsupportedReason(). Effect: homebrew-composite-status browser tier no longer blocks on these 12 being browser_compatible=false; vim-browser-bundle/browser moves skip -> pass. rootfs/browser now blocked only on bash+ncurses; shell/browser on bash/ncurses/curl/nethack (kd-1mr.4) plus modeset/fbdoom (framebuffer follow-up). Adds tailored browser smoke cases (dash/lsof/netcat) and the framebuffer skip hook. Brings in the kd-v3fs browser tooling required to run the smokes (browser-smoke/composite-status/smoke-cases/smoke-outcomes runners, the homebrew-smoke demo page, vfs-planner); those dedupe when kd-v3fs merges. Evidence under test-runs/kd-1mr.5/ (browser smoke 23 pass/0 fail/2 skip; composite-status; DISPOSITION.md). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
… (kd-k3l9) Adds a browser framebuffer/device smoke harness and uses it to certify the two rootfs/shell packages the terminal smoke (kd-1mr.5) could only skip, so the full 12-package kd-0hns rootfs/shell tap is now browser_compatible (homebrew-validate: ok). Harness: - scripts/homebrew-package-framebuffer-smoke.ts: pours the Homebrew VFS, injects the DOOM shareware IWAD for fbdoom, drives new-headless Chromium (WebGL2), runs the program, and asserts framebuffer/CRTC activity. - apps/browser-demos/pages/homebrew-fb-smoke/: boots the poured VFS with a PTY (framebuffer programs query /dev/tty and exit without one) and observes either /dev/fb0 writes (fbdoom, via FramebufferRegistry) or /dev/dri/card0 page-flip commits (modeset, via kmsAttachCanvas + a stats SAB, WebGL2 mode). Certified browser_compatible=true: - fbdoom -> /dev/fb0: bound 640x400, 1424 pixel-write frames, 249k non-blank px. - modeset -> /dev/dri/card0: 110 KMS page-flip commits at 1920x1080 via WebGL2. Sidecars regenerated via cargo xtask homebrew-sidecars (provenance shas consistent). Effect: modeset/fbdoom removed as shell/browser blockers; shell/browser now gated only on kd-1mr.4's bash/ncurses/curl/nethack. Evidence under test-runs/kd-k3l9/ (fb smoke 5 pass/0 fail; composite-status; DISPOSITION.md). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

What
Adds a browser framebuffer/device smoke harness and uses it to certify the two
rootfs/shell packages the terminal smoke (kd-1mr.5) could only skip -- so the full
12-package kd-0hns rootfs/shell tap is now
browser_compatible(homebrew-validate: ok)./dev/fb0: boots the Homebrew keg + DOOM shareware IWAD, binds a640x400 framebuffer, pushes 1424 pixel-write frames (91 MB), 249k non-blank
canvas pixels. CERTIFIED
browser_compatible=true./dev/dri/card0: 110 KMS page-flip commits at 1920x1080 viaWebGL2 (CRTC 1). CERTIFIED
browser_compatible=true.Harness
scripts/homebrew-package-framebuffer-smoke.ts-- pours the Homebrew VFS (reusingplanHomebrewVfs + buildHomebrewVfs), injects the IWAD for fbdoom, drives
new-headless Chromium (
chromiumchannel for WebGL2-in-worker), runs the program,asserts framebuffer/CRTC activity.
apps/browser-demos/pages/homebrew-fb-smoke/-- boots the poured VFS with a PTY,then observes either
/dev/fb0writes (fbdoom, viaFramebufferRegistryonChange/onWrite) or
/dev/dri/card0page-flip commits (modeset, viakmsAttachCanvas+ a stats SAB, WebGL2 mode).apps/browser-demos/vite.config.ts-- registers thehomebrew-fb-smokepage input.Two defects the harness solves: framebuffer programs query
/dev/ttyat keyboardinit and exit without a PTY (
pty: true); andkmsAttachCanvasmust run afterboot()(the worker doesn't exist before boot).Verification
test-runs/kd-k3l9/fb-smoke/summary.json).cargo xtask homebrew-validate --tap-root test-runs/kd-0hns/rootfs-shell-tap->ok (packages=12, bottles=12, ...); all 12 packages
browser_compatible=true.homebrew-composite-status(browser):shell/browserandrootfs/browsernolonger list modeset/fbdoom as blockers -- both now gated only on kd-1mr.4's
bash/ncurses/curl/nethack.
vim-browser-bundle/browserPASS.Sidecars were regenerated via
cargo xtask homebrew-sidecars(provenance shasconsistent); only
browser_compatible+runtime_supportchanged, no bottle sha/url.Stacking / review note
Stacks on kd-1mr.5 (which brought in the kd-v3fs browser tooling + certified the
10 terminal packages), which stacks on kd-0hns (#811) (the tap). Net kd-k3l9
contribution: the framebuffer harness (runner + page + vite input), the
modeset/fbdoom sidecar certification, and the evidence artifacts under
test-runs/kd-k3l9/. Suggested merge order: kd-0hns -> kd-v3fs -> kd-1mr.5 -> kd-k3l9.See
test-runs/kd-k3l9/DISPOSITION.mdfor full detail.🤖 Generated with Claude Code
