The landing page re-ran ~50 aggregate queries five times per load, then
repeated the whole sequence every 30 seconds forever — including in
backgrounded tabs. Against the live 1.44 GB database that was roughly 20
seconds of SQLite work per page load.
Move the work off the request path. A refresher thread in the viewer
process (which already runs migrations, so it works for a split-DB
install) writes two tables: daily_rollup, one row per local date, and
dashboard_snapshot, a single JSON row. A page load now reads one row.
Measured on the live database: first paint 6 requests -> 2,
/api/dashboard/summary p50 1.1 ms (304 in 0.8 ms), /api/stats 130 ms,
and a 0.32 s refresh once a minute in the background.
Make the numbers mean what they say:
- Window selectors are built from each source's retention. The page
offered "30d" and "All" against tables pruned at 7 days, so three of
four choices returned the same figure under a label that denied it.
- The incoming-packet chart reports its measured window instead of
claiming 7 days for a table pruned at 3 — it sat beside a genuine
7-day contacts chart inviting an invalid comparison.
- Days with no source data store NULL and render as gaps. Writing 0
would put a fake cliff at every retention boundary.
- Signal metrics are stored as sums and counts, never means, so any
window re-aggregates correctly.
- Delta chips compare the last two complete calendar days and say so;
the headline above them is a rolling 24 hours.
- Unmapped role ordinals (type0..type15) bucket into "Unknown".
- SNR comes from message_stats, where it is populated on every row, not
from complete_contact_tracking, where it is populated on 7%.
Kill the json_extract scans: packet_stream gains denormalized
route_type_name, payload_type_name, path_len and bytes_per_hop, written
at capture time. Aggregating those from JSON cost 3-6 s per query.
Existing rows convert a bounded batch per tick rather than in one
migration that would rewrite ~180 MB into the WAL and stall bot startup.
A partial index serves as the backfill worklist — without it the "any
rows left?" probe is a full scan costing 4.6 s per tick, and it costs
that after the backfill finishes, because finding nothing still means
reading everything.
Also: replace the per-contact hop-prefix scan with the existing bucketed
matcher and memoize the 7-day chunk set (264 ms -> 35 ms on a synthetic
100k-row database, regression-locked by a test); move the dashboard's JS
and CSS to static files, which removes the CSP nonce requirement for the
bulk of the page; and give cleanup_old_stats a future-timestamp guard,
without which rows dated 2103 are never older than the cutoff and so
live forever.
Deletes the orphaned /stats page, unreachable from the nav and rendering
stub charts that never populated. /api/stats stays as a shim with every
key name intact plus Deprecation and Sunset headers.
All schema changes are additive, so a downgraded codebase can read the
data; it would however need the new schema_version rows removed, since
MigrationRunner rejects versions it does not know.
- Updated the `[Rain_Command]` section in `config.ini.example` to include support for snow alongside rain, improving the command's functionality.
- Enhanced documentation for the rain command to reflect the new snow alias and clarify response behavior based on the selected keyword.
- Added a new `collect_stats` option in the `[Stats_Command]` section, allowing stats collection to be enabled independently of the user-facing command, with updated documentation to explain its behavior.
- Improved the web viewer documentation to clarify how stats are collected and displayed, ensuring users understand the configuration options.

- Updated documentation in `data-retention.md` and `web-viewer.md` to clarify how stats are collected and displayed, including the new `collect_stats` configuration option.
- Modified `StatsCommand` in `stats_command.py` to introduce `collect_stats`, allowing message and command statistics to be recorded even when the `stats` command is disabled.
- Adjusted logic in `record_message`, `record_command_stats`, and `record_path_stats` methods to utilize the new `collect_stats` setting for improved flexibility in stats tracking.
- Replaced direct SQLite connection calls with a context manager in various modules to ensure proper resource management and prevent file descriptor leaks.
- Introduced a new `connection` method in `DBManager` to standardize connection handling.
- Updated all relevant database interactions in modules such as `feed_manager`, `scheduler`, `commands`, and others to utilize the new connection method.
- Improved code readability and maintainability by consolidating connection logic.
- Updated `_format_path_for_display` method to support multi-byte path formatting based on `bot.prefix_hex_chars`, ensuring compatibility with both legacy and new path formats.
- Improved handling of descriptive text in paths and added fallback logic for legacy paths.
- Added a synopsis format for path display in the stats command, providing a concise representation when message limits are exceeded.
- Updated translation files for multiple languages to include the new synopsis format for path data.
- Standardized the configuration keys for various commands by replacing specific `*_enabled` keys with a unified `enabled` key across configuration files.
- Updated command classes to support fallback mechanisms for legacy configuration keys, ensuring backward compatibility.
- Enhanced the logic in the `BaseCommand` class to handle both standard and legacy keys for command enabling.
- Added tests to verify the correct behavior of the new configuration handling and legacy support for commands including Stats, Sports, Hacker, and Alert.
