Review army + adversarial passes (Claude and Codex) on the merged branch:
setup
- _prune_stale_generated scans the host dirs too (the generator already
removed the render before setup ran, so the host branch was dead), skips
symlinks in the render tree (rm -rf on a slash-terminated link empties its
target), removes a host symlink only when it resolves into gstack, cleans a
bannered real dir through _cleanup_weak_dir, recognizes frontmatter-renamed
skills, and logs through log. The always-run codex render passes every host
dir that may link to it.
- NEEDS_BUILD checks all three binaries (with $_EXE) and lib/ sources; the
browser hint and the bootstrap summary honor GSTACK_SKIP_ASIDE, treat a
requested skip as a request, and derive one skill list.
lib/aside-render.ts + bin/gstack-render.ts
- The loopback server carries a per-render secret path, checks containment on
the real path (symlink escapes are 403), and rejects malformed encoding.
- Inline eval results are one base64 line, so page text cannot forge
ASIDE_DIR= or the sentinel; the last ASIDE_DIR wins.
- runProc escalates SIGTERM to SIGKILL, bounds every wait, and clears every
timer (an uncleared one kept gstack-render alive after printing OK).
- renderTmpDir refuses a shared /tmp name owned by someone else; the work dir
and server are created inside try; goto's budget follows the render budget.
- probeAside classifies a present-but-failing CLI as ASIDE_NOT_RUNNING like
the skills' bash probe; render() retries on gstack's own browser when Aside
could not start or its private CDP bridge is gone (never on a page error
or a timeout of a running script); the CLI reports the engine that actually
rendered, exits 0 on --help, rejects non-numeric flags, documents
--wait-timeout, fences EVAL/PAGE_ERRORS as untrusted content, and names the
daemon's cookie-import JS lock remedy.
- The browse path passes --scale only when asked (a scale change rebuilds
the daemon context) and restores the viewport after a sized screenshot.
resolvers / templates
- The bash probe honors GSTACK_SKIP_ASIDE and has a perl deadline on stock
macOS; .local is no longer LOCAL (mDNS); same-origin filters compare parsed
origins; link status is HEAD-checked only on LOCAL targets; every
aside exec goes through the receipted _aside_exec prelude
({{ASIDE_EXEC_PRELUDE}}), including nine template blocks that called it
bare; the design sketch and diagram staging use private directories.
- The generator prunes only bannered renders and never a host whose
generation failed.
Docs, stale comments and dead code cleaned; goldens re-rendered; tests
updated and added for every behavior above.

lib/aside-render.ts serves the HTML's directory on loopback (Aside refuses file:// URLs), opens it with waitUntil load, prints through CDP Page.printToPDF so tagged output, outlines, header/footer templates and page numbers survive, emulates device metrics for sized screenshots, and writes in-page evaluations to files; when Aside is absent it runs the same spec through the browse daemon (newtab, load, js, pdf, screenshot, closetab) and reports ENGINE=aside|browse. bin/gstack-render.ts is the CLI skill templates call. lib/claude-bin.ts and lib/error-handling.ts become the canonical copies (browse/src re-exports them).
