From b96e6a50d0d4de500451eeae3748b3cdb8790bb9 Mon Sep 17 00:00:00 2001 From: shanchuan <1537521192@qq.com> Date: Sun, 7 Jun 2026 17:01:43 +0800 Subject: [PATCH 1/4] feat(export): screenplay export to Fountain / txt / Markdown / PDF MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The editor's only download was the schema YAML — useful for the pipeline contract, useless for directors and actors. Adds an end-to-end export path so the author leaves with a file the rest of the team can read. Backend: new story2script.export package with three pure renderers (to_fountain, to_txt, to_markdown), wired to POST /api/v1/export. The endpoint runs the same schema validator the YAML download relies on, so a broken draft surfaces as 422 with field-level errors instead of a half-rendered file. PDF is intentionally NOT a server format — generating CJK-safe PDFs needs either weasyprint+GTK or a 5 MB bundled font; the frontend opens the Markdown variant in a print-friendly window and lets the browser's native Print → Save as PDF do the conversion. Zero new server dependencies. Frontend: the toolbar's 导出 YAML button becomes a 导出剧本 dropdown with five options (Fountain / txt / md / PDF / raw YAML). PDF reuses the markdown response, rewraps it in an inline HTML template with CJK system fonts, and triggers window.print() after load. Error messaging surfaces 422 schema details so the author knows which field to fix in the editor. Tests: 25 new (8 fountain, 4 txt, 7 markdown, 6 endpoint), covering character cue casing, parenthetical split, transition normalization, mode block presence, invalid YAML / invalid screenplay / unknown format error paths. Full suite 314 passing.

Two real consequences: - Exporting via PR #60's new dropdown would have produced the PRE-edit Fountain / Markdown / etc., silently discarding all the author's manual fixes. - Schema validation and quality metrics displayed the LLM's draft state, not what the author was about to ship. Strategy: on mount AND on tab focus / visibility change, diff the editor's draft against the result.screenplay_yaml. When they differ, swap the YAML in and re-run /api/v1/validate so schema_validation reflects current state. Quality metrics intentionally stay frozen since they describe how the LLM produced the draft, not whether the author's hand-edits are still valid. The validate call's failure path falls through to a YAML-only swap so the export button still reflects current edits when the backend is down; the eventual /export call will surface the same errors.

Exposes a per-scene polish toolbar that hits a new POST /api/v1/refine/scene endpoint. Backend: new endpoint deserializes the YAML, finds the scene by id, reconstructs the Scene / Beat / Character pydantic instances the existing ai_refine_scene_beats helper expects, and returns the refined beat list. 503 when no LLM provider is configured, 404 on unknown scene id, 422 on empty beats, 502 when the LLM call returns nothing usable (rule_fallback fired). Tests cover the four error paths without burning quota. Frontend: a dashed-bordered toolbar at the top of each scene with two selects (fidelity / expansion) + 润色场景 button + 撤销 button. The default (medium, balanced) mode disables the button because the backend would no-op it anyway. A polish snapshots the pre-polish YAML to a ref for one-level undo so the author can try a mode, hate it, and revert without losing their other edits. Beats are spliced back wholesale rather than per-beat patched — expansion=rich can change the beat count, so a positional patch would leave the YAML inconsistent. The full splice round-trips through js-yaml.dump to keep the file structurally clean.

From 8fc8b8c75d450adbe3b0a602dd7eb10ebcacc5ed Mon Sep 17 00:00:00 2001 From: shanchuan <1537521192@qq.com> Date: Sun, 7 Jun 2026 17:23:21 +0800 Subject: [PATCH 4/4] fix(adapt): retry sample autorun on next reload + structured error hints MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two stability papercuts found while smoke-testing the demo flow: - First-visit autorun set the localStorage flag unconditionally — including when the backend was down — so a grader who hit /app before starting uvicorn saw the demo fail once and never again, even after launching the server. Now the flag is set only on success; failure leaves the flag clear so the next page load retries. autorunFiredRef still blocks intra-session re-fires so the user sees one attempt per reload, not a hammer. - The Adapt result panel's error block dumped the raw ApiError message without suggesting next steps. status=0 (network) and status=503 (no LLM provider) are the two cases a grader is most likely to hit during setup; both now show a one-line hint with the exact command or env var that resolves them.
