 For example: `20260131-210000 Task Streamd.md`
 
-An optional `_file_type` segment can follow the timestamp to classify the file:
-
-```
-YYYYMMDD-HHMMSS_<file_type> [markers].md
-```
-
-For example: `20260413-083000_daily.md` — the `daily` prefix is stored as the `file_type` dimension and propagates to all child shards.
-
 Within files, `@`-prefixed markers at the beginning of paragraphs or headings define how a shard is categorized.
 
 ## Commands
 
 - `streamd` / `streamd new` — Create a new timestamped markdown entry, opening your editor
-- `streamd daily [YYYYMMDD]` — Open today's daily file (or create it if missing); pass a date to open that day's file instead
 - `streamd todo` — Show all open tasks (shards with `@Task` markers), numbered for easy reference
 - `streamd todo N edit` — Edit task N in your editor, jumping to the task's line
 - `streamd todo N done` — Mark task N as done by inserting `@Done` after `@Task`

 - `[markers]`: Space-separated marker names extracted from file content

-### R21a: Daily Command Behavior
-
-`streamd daily [YYYYMMDD]` provides quick access to the daily journal entry for a given date.
-
-**Date resolution:**
-- If a `YYYYMMDD` argument is provided, it is parsed as the target date.
-- If no argument is given, today's date is used, interpreted in the repository timezone (from `.streamd.toml`, defaulting to UTC).
-
-**File lookup:**
-- All markdown files in the base folder are localized.
-- Files with `file_type = "daily"` whose root shard `moment` falls within the target date (in the configured timezone) are collected.
-- The file with the earliest `moment` is opened in `$EDITOR` (defaults to `vi`).
-
-**File creation:**
-- If no matching file is found, a new file is created at `<now_local>_daily.md` (e.g. `20260413-083000_daily.md`) containing `# ` and opened in the editor.
-- The `_daily` suffix is permanent — it identifies the file type and is not renamed after editing.
