+# Calliope changelog — 24 August 2026
+
+**Agent + Assets Management** update. Ships in Windows zip **1.2.1**.
+
+Posted in both places:
+
+- [Release v1.2.1](https://github.com/benjiyaya/Calliope/releases/tag/v1.2.1) — zip download
+- [Discussion #20](https://github.com/benjiyaya/Calliope/discussions/20) — comments
+
+Video / H3 / Generate-all: [2026-08-23](https://github.com/benjiyaya/Calliope/blob/main/docs/changelogs/2026-08-23.md).
+
+---
+
+## Agents
+
+Agents chat is a plugin harness with an event-sourced session log. UI rows and LLM history are derived from that log — they are not written on their own.
+
+### Modes
+
+- **Project-linked** — tools stay on that film (story, scenes, assets, jobs).
+- **Sandbox** — no project. `@workflow` / generate queues on hidden **Playground scratch**. The agent does **not** `create_project` just to make an image. `create_project` / `link_project` only when the user wants a film; the session then re-scopes.
+
+### Tools the agent may use
+
+- Workspace: `create_project`, `link_project`, `list_projects`.
+- Story / script: draft and edit beats, characters, locations, **misc. items**, scenes.
+- Assets / render: `enqueue_asset_jobs`, `enqueue_video_jobs`, `run_workflow`, `wait_for_jobs`, `attach_asset`.
+- `attach_asset` files a finished generate (`job_id` or path) onto a film as a character sheet, environment, or misc. item. Refuses Playground scratch.
+
+Comfy MCP `comfy_*` generate tools are **not loaded**. Agents use Calliope HTTP tools only.
+
+### Human-in-the-loop (1.2.1)
+
+- Render tools (`run_workflow`, `enqueue_asset_jobs`, `enqueue_video_jobs`) stay **hidden** until the user’s latest message asks to generate or confirms an offer.
+- Tagging `@workflow` alone is not permission. Creating a misc. item (or any text edit) is not permission.
+- Intent is read from user prose only. The machine `[Calliope context]` appendix is stripped first (`kind=image` in the appendix cannot unlock renders).
+- More than three video clips needs an explicit “all scenes / every clip” — a bare “yes” after a 2-clip offer must not enqueue the whole timeline.
+- Destructive `replace=true` regeneration on a non-empty project still needs an explicit confirm (“yes, replace” / “from scratch”).
+
+Helpers live in `harness/policy.py`.
+
+### Operator controls
+
+- Settings → Agent: **hardening rules** appended last on the system prompt (blank disables). Same text on swarm sub-agents.
+- Step budget: `agent_max_steps`.
+- Composer: `@` mentions (workflows), file attachments. Welcome chips stay on a newly created empty session.
+
+---
+
+## Assets management
+
+Three entity types on Project → Assets. All three are LLM-extracted in Draft Storyline, editable in Story, and generated as reference images here.
+
+| Type | Stored as | Video refs |
+|---|---|---|
+| Characters | `characters` | Yes — sheets / portraits |
+| Environments | `locations` | Yes — location / env |
+| **Misc. Items** | `items` | Picker can use the image; items are **not** auto-attached to scenes |
+
+Items match locations in the form (`name`, `description`, `consistency_prompt`, `reference_image_path`). Image prompt on the card maps to `(Input:prompt)` by **role**, not node id.
+
+### Generate (Assets tab)
+
+- Per-entity **Image prompt** + workflow inputs (width/height/seed…). Shared top-form Text Prompt stays empty — use the entity prompt.
+- Worker writes the output path onto the entity. Items now persist `reference_image_path` (they used to finish in the queue and stay Pending on the card). Queue label: `Name · item`.
+- Characters / locations were already attached this way.
+
+### Playground → project
+
+- **Add to project** can add as Character sheet, Background / location, or **Misc. item**.
+- Misc. item **creates a new row**. It does not replace an existing item on the project list. Name field (prefilled from the file); existing items stay unchanged.
+- Character / location still pick an existing row.
+
+### Agent path
+
+- Sandbox generate → Playground job → `attach_asset` onto a real film (sheet / env / item).
+- Or enqueue from a linked project after the user asks to generate.
+

+# Calliope changelog — 29 August 2026
+
+**Per-agent LLMs + clip-native export** update. Development branch `test-pr-25`.
+
+Full changelog index: [README](./README.md). Previous: [2026-08-24](./2026-08-24.md).
+
+---
+
+## Model per agent (Settings → Agent)
+
+You can now choose **which LLM each agent uses** — no more one model for everything.
+
+- **Settings → Agent → "Model per agent"** sits above the hardening rules. Six rows:
+  **Main agent, Planner, Story agent, Script agent, Assets agent, Video agent**.
+- Each dropdown lists every saved LLM from **Settings → LLM** plus a **(use Active LLM)** default. Blank = Active LLM, so existing setups behave exactly as before.
+- Where the assignments apply:
+  - **Main agent** — the chat loop that answers you and calls tools.
+  - **Planner** — decides single vs. swarm, and writes the final swarm summary.
+  - **Story / Script / Assets / Video agents** — the four swarm sub-agents.
+  - The **Video agent** assignment also drives the MiniMax H3 prompt rewrite.
+- Typical setup: a strong cloud model for the main agent and planner, a fast local model for sub-agents.
+
+Details:
+
+- Assignments are stored in the local `calliope_config.json` (profile **ids**, never API keys) and survive restarts.
+- Deleting an LLM profile in Settings → LLM automatically clears any assignment that pointed at it.
+- The API validates assignments: unknown roles are ignored; assigning a non-existent profile id returns `400 Unknown LLM profile for role: <role>`.
+- Settings → Agent's stacked panels now have proper spacing between them.
+
+## Export film at the clips' own FPS
+
+Film export no longer forces everything to 30 fps.
+
+- Each scene clip is probed for its real frame rate; the export targets the **majority fps across clips** (e.g. 24 fps clips export at 24 fps).
+- Ties resolve to the lower rate; if no rate can be read, the old default (30) applies.
+- Mixed-rate projects are conformed to the majority rate — the 0.5s crossfade chain needs one common timebase.
+- The export progress message now reports the rate: **"Exporting film (24 fps)…"**.
+- Everything else in the pipeline is unchanged: 1080p normalize → 0.5s crossfades → loudness normalize.
+
+## Housekeeping
+
+- Added `.gitignore` files inside `calliope-backend/` and `calliope-web/` (venv, caches, SQLite data, node_modules, build output) so each sub-folder is self-protecting in addition to the repo-root rules.
+
+## For developers
+
+- `LLMClient` accepts optional `base_url` / `model` / `api_key` overrides and gains `LLMClient.for_role(role)`; unknown roles and dangling profile ids fall back to the Active LLM.
+- New config knob: `agent_llm_assignments` (role → profile id or null), exposed via `GET/POST /api/settings`.
+- `POST /api/settings` accepts `agent_llm_assignments` with server-side validation.
+- Export: `probe()` now returns `fps` (from ffprobe `r_frame_rate`), `parse_rate()` parses rational rates like `24000/1001`, `target_fps()` votes the conform rate, and `build_ffmpeg_cmd(..., fps=...)` takes an optional override.
+- Full backend suite: **248 passed**.
