+
+## Media generation contract (load-bearing - overrides softer wording above)
+
+This project is a **non-web** surface (image / video / audio). The unifying
+contract is: skill workflow + project metadata tell you WHAT to make; one
+shell command through \`OD_NODE_BIN\` + \`OD_BIN\` is HOW you actually produce bytes.
+Do not try to embed binary content inside \`<artifact>\` tags, and do not
+write image/video/audio bytes by hand. Always call out to the dispatcher.
+
+The daemon injects these environment variables for agent sessions:
+
+- \`OD_NODE_BIN\` - absolute path to the Node-compatible runtime that started the daemon.
+- \`OD_BIN\` - absolute path to the OD CLI script. On POSIX shells run with \`"$OD_NODE_BIN" "$OD_BIN" ...\`.
+- \`OD_PROJECT_ID\` - active project id. Pass it as \`--project "$OD_PROJECT_ID"\`.
+- \`OD_PROJECT_DIR\` - active project files directory.
+- \`OD_DAEMON_URL\` - base URL of the local daemon.
+
+Run media generation through the dispatcher:
+
+\`\`\`bash
+"$OD_NODE_BIN" "$OD_BIN" media generate \\
+  --project "$OD_PROJECT_ID" \\
+  --surface <image|video|audio> \\
+  --model <model-id> \\
+  --output <filename> \\
+  --prompt "<full prompt>" \\
+  [--aspect 1:1|16:9|9:16|4:3|3:4] \\
+  [--length <seconds>] \\
+  [--duration <seconds>] \\
+  [--audio-kind music|speech|sfx] \\
+  [--voice <provider-voice-id>]
+\`\`\`
+
+Always quote the prompt value. Never splice unquoted user text into the
+command line. The command returns JSON containing either a final
+\`file\` object or a \`taskId\` for long-running renders.
+
+For long-running renders, continue with:
+
+\`\`\`bash
+"$OD_NODE_BIN" "$OD_BIN" media wait <taskId> --since <nextSince>
+\`\`\`
+
+\`media wait\` exits \`0\` when done, \`2\` when still running, and \`5\`
+when the provider task failed. Exit code \`2\` is not an error; keep polling
+with the returned \`nextSince\`.
+
+Do not emit \`<artifact>\` blocks for media. The artifact is the generated
+file written by the dispatcher, and the file viewer will render images,
+videos, and audio automatically. If generation fails, surface the actual
+stderr / exit status instead of inventing a diagnosis.
+
+Special case: \`hyperframes-html\` video projects may author composition HTML
+in \`.hyperframes-cache/\`, then render through the daemon-backed dispatcher
+with \`--composition-dir\` so Chrome-bound rendering runs outside the agent
+sandbox.
