-- Media scrape project, branch `media-scrape-project` on `veskslop-t`. Plan drafted at
-  [media-scrape/PLAN.md](media-scrape/PLAN.md) and awaiting owner review; no code yet. The command
-  adds `scrape media` to archive a channel's history over time with DiscordChatExporter-style rate
-  limiting, a SQLite store, and a new Media tab in the Web UI. Open questions in the plan: scope,
-  storage location, bytes vs. links, and tab placement.
+- Media archive project, branch `media-scrape-project` on `veskslop-t`. Design approved 2026-09-16
+  (docs: [media.md](docs/media.md), [media-scraper.md](docs/media-scraper.md),
+  [slopbot.md](docs/slopbot.md), [media-mcp.md](docs/media-mcp.md)). Decisions: scrape the channel
+  the command is sent in; slopbot (discord.js bot core) for guild channels and the puppet core
+  bridge for group DMs; one self-contained SQLite + media dir per scrape under `media-scrape/db/`
+  (gitignored); links indexed by default, downloads optional, third-party embeds never downloaded;
+  30 GiB default limit with a 90% warning and 5% no-delete overrun, usage bar and clean button in
+  Settings → Bot; Media and Bot top-level tabs; MCP hooks designed for C7.

+  Checkpoints, push after each:
+  - [x] C1 design docs, AGENTS/INDEX pointers, `.gitignore`
+  - [ ] C2 core message shape: embeds, forwards, attachment metadata
+  - [ ] C3 media-scrape store and puppet walker, tests
+  - [ ] C4 slopbot backend, tests
+  - [ ] C5 Web UI Media and Bot tabs, API routes
+  - [ ] C6 storage limit, warning flow, clean modal, settings
+  - [ ] C7 MCP service hooks
+  - [ ] C8 live verification, tuning, docs
 - Flextalk voice profile, end to end. The profile window is a movable panel that recenters on each
   open; it carries the character sliders with engine defaults and +/-2 snapping, five named
   presets, radio-kit effects (high-pass 40-400 Hz, echo 0-100, word mode with a gap in ms), and
