Remaining findings from the same triage pass. None are security
relevant; each produces a wrong user-visible result.
- greeter: treat rollout_started_at as UTC. It is written by SQLite
CURRENT_TIMESTAMP, but datetime.timestamp() read the naive value as
local time, shifting the backfill cutoff by the host's offset (7h on
PT). Users who posted inside that window were never marked as already
greeted and could be sent a welcome they should not have received.
- greeter: write greeted_at in SQLite's own format. The rollout backfill
used isoformat() while every other path used CURRENT_TIMESTAMP. "T"
sorts above a space, so ORDER BY greeted_at interleaved the two
formats wrongly, corrupting duplicate cleanup and the web viewer's
recently-greeted list.
- greeter: let an empty `channels =` disable the command. BaseCommand
reads an empty value as disabled-on-channels, but the greeter
collapsed "key absent" and "key present but empty" into one fallback
and kept greeting via monitor_channels.
- greeter: stop comma-splitting greeting text. channel_greetings split
entries on ",", so "Public:Welcome to the mesh, {sender}!" was stored
as "Welcome to the mesh" with the placeholder silently dropped. A
fragment now starts a new entry only when the text before its first
colon looks like a channel name, which keeps commas, URLs and clock
times attached to the greeting they belong to.
- wxsim_parser: match condition abbreviations longest-first. Substring
matching in dict order let RAIN shadow CHNC. RAIN, so five conditions
lost their "chance" qualifier (rain, snow, drizzle, t-storm, and
FAIR-P.C.).
- wxsim_parser: re-anchor "now" on each parse. current_date and
current_year were fixed at construction and wx_command builds one
parser at startup, so after a few days forecast dates rolled back a
year and staleness checks read permanently true.
- thesportsdb_client: hold the rate-limit read/sleep/write under a lock.
Concurrent callers read the same last_request_time, slept the same
interval and fired together, bursting past the 2.1s throttle. This
exposes an unrelated request fan-out problem in fetch_league_scores;
filed in TODO.md rather than fixed here.
- alert_command: stop duplicating the first incident. The tail treated
any single-line buffer as "header only" and appended incidents[0],
but messages after the first carry no header, so a final chunk holding
one incident had incident 0 pasted onto it. The same confusion inside
the loop also let a second incident be appended past the 130-character
limit.
- feed: reject non-positive poll intervals. -1 is truthy and was stored,
and the poller's `now - last_check >= interval` then treats the feed
as permanently due and re-fetches the URL every cycle; 0 was ignored
while still reporting success. The web viewer, which is the primary
editor, had no validation at all, and a JSON null there raised a
TypeError that aborted the poll cycle for every feed rather than one.
feed_manager falls back to the default for rows written before this.
- transmission_tracker: age out confirmed transmissions that have
repeats. Cleanup removed only repeat_count == 0, so repeated records
accumulated for the lifetime of the process, which matters on a Pi
Zero. Repeat counts are already persisted to packet_stream, so the
longer 30-minute retention loses nothing.
- mesh_graph: weighted-merge avg_hop_position when promoting an edge.
Promotion overwrote the average with the single new observation, so an
edge averaging 2.0 over 4 observations became 9.0 instead of 3.4 and
skewed subsequent path scoring.
- multitest_command: show the path that ends exactly at the display LCP.
The suffix helpers are correct in isolation; the loss happens in the
cluster formatters, where _shrink_display_lcp refuses to shrink a
single-token LCP and the trunk then rendered as "96 ┐", meaning
"everything continues past here" and dropping the bare 96 route while
the header still counted it. Now uses the file's existing "├ common"
marker. Empty suffixes are also no longer handed to the nested
renderer, which mapped them onto the same [] as a route ending at the
inner LCP and drew a row for a route that did not exist.
- sports_mappings: stop shadowing seven unique team nicknames. In one
flat dict a repeated key silently drops the earlier team, so hawks
resolved to the NBA Hawks rather than the Seahawks alias it was added
as, blazers to Kamloops rather than Portland, and rockets to Kelowna
rather than Houston. First definition now wins for hawks, giants,
jets, rangers, kings, blazers and rockets; every shadowed team keeps
its unambiguous full-name alias. The 55 city and abbreviation
collisions (chicago, sf, la, ...) are genuinely ambiguous and stay
last-wins, now pinned by a test so a new collision fails loudly
instead of passing unnoticed.
- Added a regex pattern to validate SQLite column definitions, preventing SQL injection in the _add_column() function.
- Introduced a new validation function to ensure safe column definitions are used.
- Updated repeater_manager.py to use list() for iterating over contacts, ensuring compatibility with potential changes in the underlying data structure.
- Enhanced error handling in the MessageScheduler for better debugging during scheduler shutdown and message sending.
These changes improve the security and reliability of database operations and enhance the robustness of the repeater management system.
- Updated MessageHandler to use OrderedDict for SNR and RSSI caches, implementing LRU eviction to maintain a maximum size.
- Added thread safety to rate limiting classes by introducing locks, ensuring consistent behavior in concurrent environments.
- Introduced periodic cleanup in TransmissionTracker to manage memory usage effectively.
- Added unit tests for LRU cache behavior and automatic cleanup functionality.
These changes improve performance and reliability in handling message data and rate limiting.

- 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.
- Update prefix command to accept BOTH legacy 2-char prefixes and
configured prefix_hex_chars (e.g. 4-char) during firmware transition
- Replace strict length validation with dual-length validation (2 or N)
- Ensure prefix lookups work with either input length via LIKE matching
- Update related SQL prefix extraction to use configured prefix length

Notes:
- This is an interim compatibility change to support mixed networks
where RF path data is still 1-byte while bot config may be 2-byte.
- Needs additional testing across real multi-hop scenarios and mixed
bot configurations.
- Translation updates are incomplete: only English strings were updated;
other translation files still need review.
- Behavior and UX may need refinement after real-world testing.
- Updated the configuration handling for the web viewer to use the [Bot] db_path when [Web_Viewer] db_path is unset, ensuring consistent database access.
- Added warnings in the logging to notify users when the web viewer database path differs from the bot database path, guiding them to configure it correctly.
- Refactored database path resolution logic across multiple modules for better maintainability and clarity.
- Changed the default database path in config.ini.example and related files from 'bot_data.db' to 'meshcore_bot.db' for consistency across modules.
- Adjusted final hop proximity scoring parameters in config.ini.example to reflect updated distance normalization and thresholds, enhancing scoring accuracy for LoRa networks.
- Updated documentation to clarify the shared database usage between the bot and web viewer.
- Updated comments in `message_handler.py` and `transmission_tracker.py` to specify that the repeater prefix is extracted from the last hop in the message path.
- Modified the `extract_repeater_prefixes_from_path` method to focus on the last node, improving clarity and functionality by returning only the prefix from the last hop instead of intermediate nodes.
- Updated `send_dm` and `send_channel_message` methods to include an optional `command_id` for tracking message repeats.
- Integrated transmission tracking to record and manage repeat messages, improving message handling and response accuracy.
- Enhanced `capture_command` method in `BotIntegration` to store repeat information for better analysis in the web viewer.
- Added favicon support and improved web viewer templates to display repeat information effectively.
- Implemented JavaScript updates in the web viewer to handle command updates and display repeat counts dynamically.
