block_ads is a browser-engine parameter (used by PlayWright/Camoufox
fetchers for ad-domain blocking) and is not recognised by curl_cffi's
Session.request(). When the CLI's --ai-targeted flag sets block_ads=True,
_merge_request_args forwards it unfiltered, causing:
TypeError: Session.request() got an unexpected keyword argument 'block_ads'
Add block_ads to the skip_keys set so it is stripped before the dict
reaches Session.request(), consistent with existing entries for
extra_headers and google_search.
Fixes#247
Allow users to specify a custom session_id when opening a browser session,
rather than always generating a random UUID. Useful for naming sessions
for easier management across multiple tool calls.
- Add session_id: Optional[str] = None parameter
- Validate session_id doesn't already exist before starting browser
- Fall back to uuid4().hex[:12] if not provided
- Add tests for custom session_id and duplicate detection

The Seconds type was defined as `Annotated[int, float, Meta(ge=0)]` which per PEP 593 treated float as metadata, not a type. This caused passing float values like wait=1.5 to be rejected. Fixed by using Annotated[float, Meta(ge=0)] since int is a subtype of float.
Correct fix for #240

Address review feedback: In full-path XPath generation, elements with
IDs were producing bare predicates like `[@id='x']` which creates
invalid XPath steps like `//body/[@id='main']`. Now emits `*[@id='x']`
for full-path mode (e.g. `//body/*[@id='main']/*[@id='target']`).
Short-path XPath mode unchanged — still uses `//*[@id='x']` prefix.
Also added XPath evaluation assertion to the regression test to verify
the generated selector actually selects the correct element.

When generating full-path CSS/XPath selectors, elements with id
attributes had their selector appended twice — once in the id branch
(line 30) and again unconditionally (line 50).
This produced selectors like 'body > #main > #main > #target > #target'
instead of the correct 'body > #main > #target'.
Move the append into the else branch so it only fires for elements
without an id (elements with id already append in the if branch).
Includes 2 regression tests.
On force-stop (second Ctrl+C), cancel_scope.cancel() was called BEFORE
_save_checkpoint(). Since cancel_scope.cancel() causes all subsequent
awaits within the scope to raise Cancelled, the checkpoint write was
silently aborted:
1. _save_checkpoint() uses anyio.open_file + rename — both are await
checkpoints that get cancelled immediately
2. self.paused never gets set to True (code after the aborted save)
3. The finally block sees 'not self.paused' and calls cleanup() which
DELETES the previous checkpoint file
Result: a user who ran a long crawl, pressed Ctrl+C twice to force-stop,
loses their entire checkpoint irrecoverably. The old checkpoint (from
periodic saves or a previous graceful pause) is deleted, and the new
one was never written.
Fix: move the cancel_scope.cancel() call AFTER the checkpoint save.
The save completes normally, self.paused is set to True, and only then
does the scope get cancelled to abort in-flight tasks. The finally
block correctly sees paused=True and skips cleanup.
Adds 6 regression tests covering:
- Force-stop checkpoint preservation (core regression)
- Graceful pause still works
- Force-stop checkpoint is loadable
- Normal completion cleanup still works
- Force-stop without checkpoint system
- Existing checkpoint not deleted on force-stop
curl_cffi v0.15.0 introduced CurlFollow.SAFE, which follows redirects but rejects those targeting internal/private IPs (loopback, private networks, link-local). This is now the default for all HTTP fetchers, the MCP server, and the shell curl converter.
Added FollowRedirects type alias supporting all curl_cffi redirect
modes: bool, "safe", "all", "obeycode", "firstonly".
