The known-contact gate for DM delivery returns before anything is recorded, so
a bot that keeps no contacts dropped every warning and wrote no rows: the page
showed "No warnings decided yet" indefinitely beside a status card saying it
was sending, and nothing distinguished a clean mesh from one where every
warning was being discarded. Only a debug log said otherwise.
Withheld warnings are now counted per local day in bot_metadata — a counter
rather than event rows, because this fires ahead of the cooldowns that would
rate-limit rows, so logging each one would bury the decisions worth reading.
The status card shows it, and the empty log explains itself and points at
channel delivery.
Also from the verification pass:
- The percent test built its value with config.set and a doubled %, which
set() is the one input that cannot produce the bug. It now uses read_string
with a bare %, and I checked it fails against raw=False by substituting
DEFAULT_MESSAGE — the actual failure mode.
- docs still said the bot identifies itself by public key, contradicting the
section forty lines above. On this path it is name-only, and that means the
self-exemption is spoofable; the doc says so.
- delivered_today folded dry runs in with real sends, so a morning's preview
read as afternoon transmissions. previewed_today is now separate and the
figure follows the current mode.
- TRIM(MIN(channel)) so a whitespace-padded historical row cannot become the
display name for a merged channel.
**A `global` verdict now requires RF correlated to the message.** It was also
reachable through `_is_confirmed_global_flood`'s argument-from-absence route
("no scope-eligible packet in the window, therefore unscoped"), so a row that
literally said TC_FLOOD, or a scoped ADVERT that the GRP_TXT filter excluded,
came back as "no region code". That inference is fine for deciding whether a
`*` in flood_scopes authorizes a reply; it is not fine for accusing someone of
a misconfiguration. Channel messages still correlate through the payload match
(#255), so the ordinary case is unaffected.
**A `%` in the warning message no longer wedges config reload.** `_get` read
without `raw=True`, so configparser's interpolation raised, the error was
swallowed, and the bot transmitted the default wording instead. Worse, the
bot's own `_validate_config_snapshot` iterates `config.items(section)` and
would reject every hot reload until the file was hand-edited. The save endpoint
now rejects `%` outright and caps the message at 500 characters, and the read
is raw so a hand-edited value is still honored.
**One unreachable sender no longer eats the daily cap forever.** The cap counted
failed attempts but the per-sender cooldown did not, so a node the radio cannot
reach was retried every `min_unscoped_messages` messages indefinitely and no
real offender was ever warned. Both count attempts now. The regression test
fails with three sends against the old filter.
**The sender is a display name, not an identity.** MeshCore's CHANNEL_MSG_RECV
carries no public key, so `sender_pubkey` was always empty on this path and the
only identity is a prefix anyone with the channel key can forge. DM delivery
now requires a contact the radio already holds, which bounds the bot to nodes
it knows and stops failed sends spending cap slots. Two tests asserted the
opposite because the fixture supplied a pubkey the radio never sends; they now
run with what the call site actually passes, and the docs no longer claim
pubkey identity.
Also: a negative `max_warnings_per_day` fell back instead of clamping to the
"unlimited" sentinel; tallies group case-insensitively so a `#` or case change
does not split a channel; retention uses the same clock the rows are written
in; the status figure shows delivered with attempts beside it, rather than a
count of four next to "last warning: none yet"; and the channel bars are scaled
over classified traffic so their width equals the percentage printed beside
them (33.7% was drawn at 28.7%).
A channel message with no "Name: " prefix falls back to a stand-in name.
That is not a node: every such message shares the identity, so they would
accumulate a run together and then get a DM addressed to a contact that
does not exist. The hook now passes no sender for those, so they are still
counted but can never earn a warning. The literal is a named constant and a
test pins the hook's guard to it.
Also folds the channel body-budget formula into models.channel_body_limit
rather than letting the web viewer keep a fourth copy of
"max(130, 160 - len(name) - 2)"; BaseCommand and CommandManager now call it
too, and 158 becomes models.DM_BODY_LIMIT.
Recording the decision after the send left an await between the cap check
and the row that check reads. Two channel messages in flight both passed a
cap of one and both transmitted; the new test fails with two sends against
the old ordering.
Every gate and the reservation now run with no await between them, so on the
single event loop they are atomic. A failed send corrects its own row to
'failed' and releases the mesh cooldown, but the row stays and still counts
against the daily cap: a send that reported failure may have put something on
the air before it did.
Also from a self-review pass: bound the per-sender run table (an unbounded
dict on the channel-message path is a slow leak), identify the bot's own node
by public key rather than only by the configured name, and respect
channelpause.
Closes#279.
A MeshCore client with no region configured sends every channel message as
a plain FLOOD, which every repeater on the mesh rebroadcasts. This adds two
things: free observation of how much of that the bot hears, and an opt-in
warning to the senders.
Observation classifies each channel message as scoped, global or unknown and
tallies it per channel per local day. It costs one upsert and no airtime, and
it is what lets an operator see the size of the problem before deciding to
spend airtime on it. The classification runs ahead of the flood_scopes
allowlist, because an unscoped message is exactly what that allowlist drops.
Warnings only ever fire on positive RF evidence of an unscoped FLOOD. Absence
of correlation is not proof that a sender omitted a region, so it classifies
as unknown and stays quiet. They are off by default, start in dry run, and are
fenced by min_unscoped_messages, a per-sender cooldown, a mesh-wide cooldown
and a daily cap on attempts. Dry run consumes the same budget it previews, so
the log is what going live would put on the air, not an upper bound. All three
limits read from the database, so a restart cannot release a burst.
Channel-delivered warnings go out at global scope on purpose: the recipient is
by definition outside any region the bot replies under.
New Settings -> Region Warnings page in the web viewer covers all of it. Its
dark-mode striped rows exposed a pre-existing base.html bug where Bootstrap's
light-theme text color survived on a dark row background (~1.3:1); fixed there
for every table in the app.
