Carry prompt panel UX and backend follow-ups from source commits 0c112d9 and 99d8dc2 onto current dev. Keep recovery-only Repair on the canonical lock contract already merged upstream, preserve outgoing drafts, and bound external source reads. Co-authored-by: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>
Match the GUI test script to CI file isolation. Non-isolated runs allow a pre-existing fixture to leave a readonly React act global that prevents prompt-panel tests from entering their test bodies. Preserve the pinned runner, all assertions, product behavior and dependency lockfiles.

Keep the strict GUI script assertion aligned with the isolated pinned runner command. The runtime checks still prove the Bun pin, working directory, name filters and failure propagation.
Resolve the published config target before comparing rename destinations so Windows short TEMP paths still exercise the post-write superseded races. Use a noncanonical fixture spelling and verify each injected edit before checking file and journal preservation.

… canonical The scalar line editor matched assignments line by line, so assignment-shaped prose inside a multiline developer_instructions value could be edited as the real key: a confirmed base import rewrote the prose and left model_instructions_file pointing at the original file. Lines are now classified by lexical scope across the whole file; only lines that start outside every string and composite span are assignment or table candidates, and an unterminated span refuses the edit before any write. Ordinary multiline values and multi-line arrays keep working. Quoted toggle keys are now read with the same decoded-key matcher the writer uses, so a successful write no longer returns a defaulted snapshot. The base variant dialog reconciles an existing variant to its canonical saved title and body when no newer edit arrived, so a normalized save is not reported dirty.

Maintainer review follow-up pushed as 54c6819 on this branch.
New regressions live in |
Toggle reads matched quoted assignments line by line, so assignment-shaped prose inside a multiline value could be reported as the setting and a successful write could return a snapshot that disagreed with the file. The lexical scanner moves to encoding.ts and toggle reads use scopedBool, which skips lines that start inside a string or composite span and bounds tables by top-level headers only. Files whose spans never close keep the plain scan.
When Bun refuses a Codex-valid config (for example an i64 beyond the JS safe range), the model_instructions_file reader falls back to a line scan. That scan read root lines without lexical scope, so a model_instructions_file line inside a multiline value could be taken as the setting and a confirmed base import would install that file. The fallback now uses scopedRootLines, which skips lines that start inside a string or composite span.
…lback The fallback line scan kept the trailing carriage return, and JavaScript's '.' does not match it, so a CRLF line with a trailing comment was reported as unreadable and a base import refused an existing source. Strip the CR before matching.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Do not scan unclosed spans as root-scope lines.
When lexicalLineStarts returns null for an unclosed multiline value, scopedRootLines returns rootLines(content). A model_instructions_file assignment inside that value can then be treated as the real setting. The prompt snapshot can show a false base selection, and an import refusal can report the false path. The external file is not read, but the UI reports incorrect configuration state.
Return no scoped lines for an unclosed span. This preserves parser-fallback reads when spans close and keeps unreadable configurations from producing a false setting.

…port Cancel through the draft guard Two review findings at dd1133c: - importBaseVariant compared the preview hash before either write lock was held, so a source rewritten during lock acquisition was activated as the older approved copy. The locked build now re-reads the source and refuses with import_body_changed unless it still serializes to the previewed hash and path; the unreferenced variant copy is cleaned up as for other provable refusals. - The import preview's Cancel called onClose directly and unmounted the dialog, discarding unsaved base-variant drafts without the confirmation Close and Escape show. It now uses requestClose. Both regressions fail on dd1133c and pass here.

Hosted CI on this head decides readiness. Two follow-ups are left out of scope: reader parity for the alternate header forms that are now refused, and the CON-3 window narrowing to the instant between the locked re-read and the config publish. Co-authored-by credit for @luvs01 is preserved by the squash of this PR. Update: Update: |
…rences it The locked import recheck added in ca9b7e6 refuses with import_body_changed when the selection is no longer the previewed external file. Cleanup treated every non-uncertain refusal as proof the copy was unreferenced, so a non-cooperating writer that selected the visible copy in the meantime was left pointing at a deleted file. Cleanup now deletes the copy only after variantStillReferenced shows the live config does not name it, for every refusal. The new regression fails on ca9b7e6 and passes here.
…rence variantStillReferenced compared only lexically resolved paths, so a live model_instructions_file naming a symlink to the freshly copied variant was read as unreferenced and the refused import deleted the prompt in force. It now also compares canonical destinations, and keeps the copy unless the selection provably does not exist. The new regression fails on d19c316199 and passes here.
…dows The journal retry regressions intercepted renameAtomicFile only when the destination equalled realpathSync(fixture path). On windows-latest the plain realpath of a temp-dir path can keep its 8.3 short form while the transaction publishes to the realpathSync.native form, so the hooks never fired (windows 4/9 in run 38087693507: intercepted=false, peerEdits=0). Both sides are now resolved with realpathSync.native. Test-only change.
