fix(templates): replace leaked internal note in Seedance 2.5 FLF2V default prompt

[purzbeats]

PR Created by the Glary-Bot Agent

---

Problem

The api_seedance2_5_flf2v template ("Seedance 2.5: FLF2V") shipped with an internal message baked in as the default prompt value on the ByteDance2FirstLastFrameNode:

Anyone opening the default template in ComfyUI saw this text in the node UI. Introduced in #1101 (Wan Animate 2 and Seedance2.5 templates).

Fixes PN-825 — https://linear.app/comfyorg/issue/PN-825

Fix

Replaced the leaked text with a generic cinematic prompt. The replacement describes the transition actually shown by the template's own bundled assets (pool_start_frame.png → pool_end_frame.png: an aerial wide of an empty resort pool ringed by a crowd → an overhead close-up of that pool packed with partiers), which also matches the "empty-to-packed" example called out in this template's index.json description:

Cinematic aerial shot, smooth continuous camera movement: the drone slowly descends and pushes in toward the pool below. First frame: high wide aerial view of a sunlit pastel resort, a large empty turquoise pool with a crowd gathered along its edge. Last frame: overhead close-up of the same pool now packed with people celebrating in the water, arms raised and drinks in hand, parasols and inflatables around the deck. Bright midday sunlight, sparkling water reflections, warm summer color grading, photorealistic, hyper-detailed 8K, no text overlays.

The style follows the sibling FLF2V templates (api_seedance2_0_flf2v, api_bytedance_seedance1_5_flf2v), which use the same "first frame: … last frame: …" camera-move phrasing.

packages/core/.../manifest.json is regenerated (npm run sync:bundles) for the new asset SHA256 — required, or validate:manifests fails.

Scope

Two lines, one string value. No other widget values changed — verified in a live graph that every widget still maps to its original value (720p, duration 5, generate_audio true, mp4, seed 0, randomize, watermark false, empty asset ids), so no widgets_values array shift.

Grepped every repo in the workspace for the leaked string — this template JSON was the only source occurrence. The copy under packages/json/.../templates/ is gitignored and build-generated; it regenerates correctly from this change.

Verification

• npm run validate:templates — ✅ all validations passed
• npm run validate:manifests — ✅ no errors (82 pre-existing unrelated warnings about unreferenced template files)
• pytest packages/core/tests — ✅ 38 passed
• Spellcheck unaffected — CI only spellchecks MarkdownNote/Note nodes and index.json title/description; confirmed via extract_workflow_text.py that this prompt is not in the spellcheck corpus
• End-to-end: started ComfyUI (--cpu) + frontend dev server, confirmed the backend serves the corrected prompt from /templates/api_seedance2_5_flf2v.json, then loaded the template into a real graph and inspected the node

The screenshot below is the same node from the bug report, now showing a normal prompt, with both input frames loading and no errors.

No findings to address here — CodeRabbit skipped the review because the PR is a draft, which is intentional on my side (our agent workflow opens PRs as drafts for a human to promote). No code changes were made in response.

Triggering a scan anyway so the change still gets covered before anyone promotes it, since this one is gating the prod template merge.

For reviewer context, the diff is two lines:

• templates/api_seedance2_5_flf2v.json — the leaked internal note in the ByteDance2FirstLastFrameNode default prompt replaced with a generic cinematic prompt describing the template's own bundled pool_start_frame.png → pool_end_frame.png transition.
• packages/core/.../manifest.json — regenerated asset SHA256 via npm run sync:bundles (required, or validate:manifests fails).

Already verified: validate:templates ✅, validate:manifests ✅ (no errors), pytest packages/core/tests ✅ 38 passed, plus an end-to-end load of the template in a live ComfyUI + frontend to confirm the node renders a normal prompt and every other widget value is unchanged (no widgets_values array shift).

Thanks for the review @synap5e. The approval came through with no comment body or inline comments, so I read it as a straight approve — no changes made, branch is still at the reviewed commit 363b355.

CI on that commit for the record:

• Spellcheck ✅ both checks passed (as expected — prompt widgets aren't in the spellcheck corpus, only MarkdownNote/Note nodes and index.json)
• ComfyUI Node Compatibility — "review suggested", but it's informational/non-blocking and api_seedance2_5_flf2v.json isn't among the 88 flagged templates. All 332 findings are pre-existing deprecated-node warnings on other templates, 0 errors.

Left as a draft per our agent workflow — ready for a maintainer to promote and merge whenever. Since this one is gating the prod template merge, no need to wait on me.

This looks superseded: #1106 landed the same fix on 2026-08-08 and main's flf2v default prompt no longer carries the internal text. That is also where the conflict here comes from, since both PRs rewrite the same widget value.

Suggest closing unless there is something in this version worth keeping over what merged.
