Three call sites in webclaw-fetch used .expect("semaphore closed") on
`Semaphore::acquire()`. Under normal operation they never fire, but
under a shutdown race or adversarial runtime state the spawned task
would panic and be silently dropped from the batch / crawl run — the
caller would see fewer results than URLs with no indication why.
Rewritten to match on the acquire result:
- client::fetch_batch and client::fetch_and_extract_batch_with_options
now emit BatchResult/BatchExtractResult carrying
FetchError::Build("semaphore closed before acquire").
- crawler's inner loop emits a failed PageResult with the same error
string instead of panicking.
Behaviorally a no-op for the happy path. Fixes the silent-dropped-task
class of bug noted in the 2026-04-16 audit.

* fix(cli): close --on-change command injection via sh -c (P0)
The --on-change flag on `webclaw watch` (single-URL, line 1588) and
`webclaw watch` multi-URL mode (line 1738) previously handed the entire
user-supplied string to `tokio::process::Command::new("sh").arg("-c").arg(cmd)`.
Any path that can influence that string — a malicious config file, an MCP
client driven by an LLM with prompt-injection exposure, an untrusted
environment variable substitution — gets arbitrary shell execution.
The command is now tokenized with `shlex::split` (POSIX-ish quoting rules)
and executed directly via `Command::new(prog).args(args)`. Metacharacters
like `;`, `&&`, `|`, `$()`, `<(...)`, env expansion, and globbing no longer
fire.
An explicit opt-in escape hatch is available for users who genuinely need
a shell pipeline: `WEBCLAW_ALLOW_SHELL=1` preserves the old `sh -c` path
and logs a warning on every invocation so it can't slip in silently.
Both call sites now route through a shared `spawn_on_change()` helper.
Adds `shlex = "1"` to webclaw-cli dependencies.

* chore(brand): fix clippy 1.95 unnecessary_sort_by errors
Pre-existing sort_by calls in brand.rs became hard errors under clippy
1.95. Switch to sort_by_key with std::cmp::Reverse. Pure refactor — same
ordering, no behavior change. Bundled here so CI goes green on the P0
command-injection fix.

Sites like Bluesky emit JSON-LD with literal newline characters inside
string values (technically invalid JSON). Add sanitize_json_newlines()
fallback that escapes control characters inside quoted strings before
retrying the parse. This recovers ProfilePage, Product, and other
structured data that was previously silently dropped.

Docker CMD gets overridden by any args, while ENTRYPOINT receives them.

Crawls are same-origin by default. Enable allow_subdomains to follow
sibling/child subdomains (blog.example.com from example.com), or
allow_external_links for full cross-origin crawling.
Root domain extraction uses a heuristic that handles two-part TLDs
(co.uk, com.au). Includes 5 unit tests for root_domain().

Try /sitemap_index.xml, /wp-sitemap.xml, and /sitemap/sitemap-index.xml
after the standard /sitemap.xml. WordPress 5.5+ and many CMS platforms
use non-standard paths that were previously missed. Paths found via
robots.txt are deduplicated to avoid double-fetching.

Stress testing showed 33% of proxies are dead, causing 30s+ timeouts
per request with 3 retries (worst case 94s). Reducing timeout from 30s
to 12s and retries from 3 to 2 brings worst case to 25s. Combined with
disabling 509 dead proxies from the pool, this should significantly
improve response times under load.

failure on the merge commit.

Two related fixes for content being stripped by the noise filter:
1. Remove <form> from unconditional noise tags. ASP.NET and similar
frameworks wrap entire pages in a <form> tag — these are not input
forms. Forms with >500 chars of text are now treated as content
wrappers, not noise.
2. Add safety valve for class/ID noise matching. When malformed HTML
leaves a noise container unclosed (e.g., <div class="header"> missing
its </div>), the HTML5 parser makes all subsequent siblings into
children of that container. A header/nav/footer with >5000 chars of
text is almost certainly a broken wrapper absorbing real content —
exempt it from noise filtering.
Pages like Express.co.uk live blogs nest 200+ DOM levels deep, overflowing
the default 1 MB main-thread stack on Windows during recursive markdown
conversion.
Two-layer fix:
1. markdown.rs: add depth parameter to node_to_md/children_to_md/inline_text
with MAX_DOM_DEPTH=200 guard — falls back to plain text collection at limit
2. lib.rs: wrap extract_with_options in a worker thread with 8 MB stack so
html5ever parsing and extraction both have room on deeply nested pages
Tested with Express.co.uk live blog (previously crashed, now extracts 2000+
lines of clean markdown) and drudgereport.com (still works correctly).
Sites like Drudge Report use <table> for page layout, not data. Each cell
contains extensive block-level content (divs, hrs, paragraphs, links).
Previously, table_to_md() called inline_text() on every cell, collapsing
all whitespace and flattening block elements into a single unreadable line.
Changes:
- Add cell_has_block_content() heuristic: scans for block-level descendants
(p, div, hr, ul, ol, h1-h6, etc.) to distinguish layout vs data tables
- Layout tables render each cell as a standalone section separated by blank
lines, using children_to_md() to preserve block structure
- Data tables (no block elements in cells) keep existing markdown table format
- Bold/italic tags containing block elements are treated as containers
instead of wrapping in **/**/* (fixes Drudge's <b><font>...</font></b>
column wrappers that contain the entire column content)
- Add tests for layout tables with paragraphs and with links
Research results saved to ~/.webclaw/research/ (report.md + full.json).
MCP returns file paths + findings instead of the full report, preventing
"exceeds maximum allowed tokens" errors in Claude/Cursor.
Same query returns cached result instantly without spending credits.

report + sources + findings, prints report to stdout
- --deep: longer, more thorough research mode
- MCP extract/summarize: cloud fallback when no local LLM available

boring-sys2 builds BoringSSL from C source via cmake. For aarch64 cross-

wreq uses BoringSSL (via boring-sys2) which needs cmake and clang

Migrated webclaw-fetch from webclaw-tls (patched rustls/h2/hyper/reqwest)
to wreq by @0x676e67. wreq uses BoringSSL for TLS and the http2 crate
for HTTP/2 fingerprinting — battle-tested with 60+ browser profiles.
This removes all 5 [patch.crates-io] entries that consumers previously
needed. Browser profiles (Chrome 145, Firefox 135, Safari 18, Edge 145)
are now built directly on wreq's Emulation API with correct TLS options,
HTTP/2 SETTINGS ordering, pseudo-header order, and header wire order.
84% pass rate across 1000 real sites. 384 unit tests green.

When a fetch returns a challenge page (small HTML with Akamai markers),
automatically visit the homepage first to collect _abck/bm_sz cookies,
then retry the original URL. This bypasses Akamai's cookie-based gate
on subpages without needing JS execution.
