Introduces an `update` save mode that allows the LLM to revise an
existing script. Distinguishes this from `append`, which now performs
a blind append. Updates the save prompts and system instructions
accordingly.
A second /save with nothing recorded and no prompt sent an empty user
message, which Anthropic rejects (HTTP 400: text content blocks must be
non-empty). Bail out early instead, telling the user to run commands or
give a prompt.
When a /save targets an existing script (a remembered save path, or
choosing append for an existing file), feed the file contents back to
the model and ask for the complete updated script, then overwrite. This
makes '/save fix X' actually fix the saved script — previously the
blind regeneration was appended after the buggy one. The --no-llm dump
path keeps its verbatim append semantics.
Prior to adding support for preload/modulepreload, we'd just fire a dummy
load event on the next tick. But now that we have proper handling for these, we
should fire load (or error) when the file is loaded (or failed to load). Our
artificial Frame._to_load becomes a bit more generic...it still supports
synthetic loads (e.g. for images), but it also supports "error" event.
ScriptManage and ScriptManagerBase now queue a load/error event when a preloaded
script completed/errors.
Add the reflected IDL attributes to the existing HTMLSourceElement,
which previously reflected none: src (resolved as a URL like
HTMLEmbedElement.src), srcset, sizes, media, type, width and height.
Mirrors the reflection idiom used by HTMLEmbedElement. width and height
are reflected as strings, matching the sibling HTMLEmbedElement
accessors. Adds element/html/source.html covering parse-from-markup,
property/attribute round-trips and src URL resolution.
This adds more comprehensive and correct support for slot assignment. The
changes can be broken down into 3 buckets:
1 - Slot.assign is now implemented, and general correctness around finding/
assigning slots (e.g. Text.assignedSlot)
2 - Event dispatching for "composed" (propagating through the shadowdom) better,
specifically around the composedPath and slots
3 - The slotchange event is fires at the right time (snapshot before mutation
fire after mutation).
A number of WPT tests now pass, and there should be real-world impact for
slot-heavy frameworks (e.g. lit)
Every 300-399 status was routed into the redirect path, where the missing
Location header fails the transfer with error.LocationNotFound — the old
document is destroyed and nothing replaces it. Per the fetch standard's
HTTP-redirect fetch ("If locationURL is null, then return response") and
RFC 9110 §15.4, a 3xx without Location is a normal final response whose
body must be delivered. Guard both the redirect dispatch and the 3xx
skip-body branch on the header's presence so such responses fall through
to the regular completion path.

:has() arguments may start with an explicit combinator (":has(> div)",
":has(~ p)", ":has(+ span)") and are anchored at the element being
matched. Absolutize each argument at parse time by prepending a :scope
anchor segment, then match candidates with :scope bound to the element,
searching the parent's subtree for sibling-anchored arguments. This also
anchors plain arguments at the element, so ":has(span p)" no longer
false-positives when the span is an ancestor of the element.
Closes#2711
The WebSocket opening handshake must carry the document's origin in an
Origin header when initiated from a browser client (RFC 6455 §4.1), and
origin-checking endpoints (CSRF protection on WS servers) reject
upgrades that arrive without it. WebSocket.init already assembles extra
upgrade headers (Sec-WebSocket-Protocol, Cookie) but never added Origin.
Serialize the executing document's origin via URL.getOrigin next to the
existing header setup — "null" for opaque origins (about:blank, data:),
matching what Chrome sends. The TestWSServer captures the upgrade's
Origin header and exposes it via a new get-origin command; an
origin_on_upgrade fixture in websocket.html asserts the served page's
origin arrives on the upgrade.
Closes#2709
Per the HTML Standard's "update the current document readiness" steps,
every change to document.readyState must fire a readystatechange event
at the Document - twice during a normal load: when readiness becomes
interactive (before DOMContentLoaded) and when it becomes complete
(before the load event). The readiness flips in Frame.zig updated
_ready_state but never dispatched the event, so page scripts driving
their lifecycle off readystatechange never observed any transition.
Dispatch the event (non-bubbling, non-cancelable, trusted) right after
each flip, mirroring how DOMContentLoaded is emitted.
Closes#2707
Updates agent documentation to reflect the removal of the status bar
in favor of ghost hints. Also documents the `/model` command and
updates the JS mode prompt examples.
Network.setExtraHTTPHeaders applied caller headers with a plain
curl_slist append. Requests are seeded with a default `User-Agent:
Lightpanda/1.0`, so a caller-supplied User-Agent produced two
User-Agent entries; libcurl keeps the first and the override was
silently dropped (origins always saw `Lightpanda/1.0`). Other headers
worked because they had no default to collide with.
Add Headers.set, which replaces any existing header with the same
(case-insensitive) name before appending, and use it when applying the
CDP extra headers. This matches Chrome, where Network.setExtraHTTPHeaders
overrides default request headers.
Refs #2704
Updates isocline to support idle callbacks and registers a hook to
pump the session's curl multi while waiting for user input. This
prevents connection timeouts. Also refactors the idle pumping logic
into `Session.idleSlice` to share it with the MCP server.
Will have to come up with a solution for search getter/setter and URLSearchParams still; We've also encountered with a bug in URLSearchParams, a fix for it will also be included in the second phase.
