- Remove unused parameters from save helper functions.
- Inline and simplify save path duplication and file writing.
- Clean up optional unwrapping for the recorder.
Add a REPL-only `/save [filename.lp]` command that persists the current
interactive session as PandaScript without requiring the user to start the
agent with `-i <script>`. The command records the same replayable actions as
the existing script recorder, but keeps them in memory until the user chooses
to save.
Functional behavior:
- During a REPL session, record replayable browser actions into an in-memory
script buffer.
- Manual slash commands are recorded through the same PandaScript formatting
and filtering rules used by file recording.
- Natural-language turns record their prompt as a `# ...` comment only when
the LLM turn produces at least one successful replayable tool call.
- Failed LLM tool calls are skipped, and repeated successful `/extract` calls
keep only the last successful extract, matching the existing recorder logic.
- `/save filename.lp` writes the current in-memory recording to that file.
- Bare `/save` creates a random `session-<hex>.lp` file on first save.
- If the first save targets an existing file, prompt with the existing numbered
TTY picker and ask whether to replace or append.
- After the first successful save, the REPL session is locked to that filename:
later `/save` or `/save same-file.lp` appends to the same file without
prompting, while `/save other-file.lp` is rejected.
- After each successful save, reset the in-memory recorder so future saves only
append actions entered since the previous save.
- On any `/save` error or cancellation, keep the in-memory recorder intact so
the user can retry without losing captured actions.
- Restrict `/save` filenames to local file names, not paths, to keep behavior
scoped to the current directory.
Code changes:
- Add `Recorder.Memory`, an in-memory recorder that shares the existing
`Command.isRecorded`, `Command.format`, comment formatting, and `LP_*`
reverse-substitution behavior with file recording.
- Add `Recorder.Memory.reset()` so `/save` can clear only successfully saved
deltas.
- Add `/save` to the REPL meta command table and help/completion surface.
- Add `save_buffer` and `save_path` state to `Agent`.
- Feed manual REPL tool calls into `save_buffer` alongside the existing optional
file recorder.
- Extend LLM turn recording with a `capture_for_save` flag so natural-language
REPL turns can be captured without affecting non-REPL script/self-heal paths.
- Implement `/save` handling in `Agent`:
- parse and validate the optional filename,
- choose replace/append for existing first-save targets,
- remember the first successful save path,
- enforce the single-destination rule for the rest of the session,
- append later deltas by default,
- commit remembered path state only after a successful file write.
- Add focused coverage for the memory recorder’s filtering and reset behavior.
This is a bit all over the place.
1 - Replace libidn2 with rust-idna. It looks like there are different idna
profiles, and rust-idna (from the servo project) implements the whatwg
one. libidn2 would be too strict in some cases and not strict enough in
others. (Gemini says I could use libidn2 for this, but what it suggested
didn't work, and I couldn't figure it out myself, and claude insisted it
_did not_ have the correct implementation for what we want).
2 - We previously only ran a URL through idna if it wasn't ascii. Turns out
we also need to run it if there's a "xn--" (aka, an IDNA ACE prefix) in
there. This helps us pass hundreds of WPT cases, and it's pretty cheap.
3 - Implement more of the Area WebAPI. Mostly copied from Anchor.
4 - Add username/password accessor to Anchor/Area
5 - window.open validates the URL (i.e. tries to resolve it and handles the
error)
6 - Invalid idna conversion maps to a TypeError
7 - Cleanup closed popups on the next tick (like destroyed pages), rather than
at an interval or on shutdown. This one seems unrelated, but some of these
tests are opening hundreds (thousands?) of popups and then closing them.
If a synthetic url (blob URL) causes a navigation event, the frame abort will
deinit the transfer, causing the `defer transfer.deinit()` atop Synthetic.run
from firing. Flag the transfer as .completing to prevent this from happening.
This mimics what non-synthetic urls do.
Adds a pretty simplistic Notification WebAPI. Also adds a dummy drawImage to
CanvasRenderingContext2D.

Previously, Cookie.Jar.add would only conditionally take over the cookie. The
caller had no way to know whether or not to deinit it. This could result in
a double-free on certain error paths.
Cookie.Jar.add now unconditionally takes ownership of the cookie.
Move the per-Window storage bucket to an origin-keyed Shed on the Session
so localStorage and sessionStorage survive navigation within an origin,
matching the Web Storage spec.
Also fixes two pre-existing bugs surfaced by this work:
- setItem's quota counter was incremented on every call, never
decremented on overwrite — five same-key overwrites tripped the cap
spuriously. Now subtracts the old value's length first.
- Shed.getOrPut used allocator.free on a single-pointer allocation
where allocator.destroy was required, and inserted into _origins
before its dependent allocations could fail. Reordered so the entry
is only put once both key dupe and bucket creation have succeeded.
Adds an MCP test that round-trips localStorage between two origins via
the eval tool to lock in the persistence + isolation contract.
I noticed that `fetch www.openmymind.net` worked but, `fetch www.example.com`
didn't. www.openmymind.net redirects to `https://www.openmymind.net/` so
in `frameHeaderDoneCallback` we get the updated response.url(). www.example.com
doesn't redirect, so self.url remains `www.example.com` which just doesn't work
at various parts of the code (Location.init, RobotsLayer...).
Added a quick check in Navigate, if the URL isn't a "complete" URL, stick
"http://" infront. There are probably cases where this is wrong, e.g.
'javascript:...' but these don't work anyways.
(Curl works with www.example.com of course).
I'm not sure how this is happening, but we occasionally see an attempt to
execute a null v8::Function (from crash reports). It seems pretty clear that
this is a Global that is being reset, but I can't figure out a path where
a global is reset while a callback is still active. So, in != .Debug mode, we
null check functions before executing and return an error.
This potentially will work without causing any new/different issues. If this is
a global being reset, than we must be in some teardown state, and it probably
doesn't matter if a JS callback is or isn't executed.
In case anyone ends up here and wonders about the guard, here's a stack from
a crash dump:
```

Three changes:
- js.Execution now has a page (instead of calling exec.context.page)
- js.Execution now has a session (instead of calling exec.context.page.session)
- js.Execution.context renamed to .js to be consistent with Frame and WGS
Navigator properties moved from data properties to real accessors. This impact
how they're seen (and potentially treated) by JS code.
These change result in https://www.browserscan.net/bot-detection correctly
rendering. When paired with https://github.com/lightpanda-io/browser/pull/2561
we now render that page correctly (still detected as a bot, but we no longer
fail to render)
window.console (and many others) should be settable. This is the [Replaceable]
WebIDL attribute.
This improves loading of https://www.browserscan.net/bot-detection which would
immediately break/fail because we would throw on window.console setting.
This appears to come from obfuscator.io's disableConsoleOutput flag, so the
issue might be relatively common.
We currently skip capturing 401 and 407 bodies. This appears to be an
optimization with the intent that it won't be needed. While that might be true
in some cases (though, not sure when), it isn't always true. A page.navigate
to a 401 should display the content.
(Also, tried to silence meaningless BrokenPipe noise in tests).
