Path distance was still leaking between concurrent requests three ways,
all of which Codex reproduced:
- The formatter fell back to shared instance state whenever the request's
own value was None, so a request with no measurable distance rendered
another request's. It now consults instance state only when there is no
request to read from.
- One extraction branch still called _decode_path without the request, so
that route stored its distance on shared state alone.
- _get_sender_location read the shared _current_message, so an
interleaved command could measure from the wrong sender. It takes the
request's message, falling back to the shared value only for direct
calls that pass nothing.
Scope authorisation: '*' permits unscoped global traffic, not traffic of
unknown scope. When a scope-eligible packet was heard but could not be
tied to this message, its scope is unknown and '*' no longer admits it.
Deliberately narrower than the reviewer suggested: when no scope-eligible
packet was heard at all, '*' still applies, because nothing scoped being
heard is what a genuinely global message looks like. Requiring positive
proof of FLOOD in that case would silence legitimate global replies
whenever correlation is unavailable, which is too much availability to
trade for the residual risk.
Correctness:
- {path_distance} was always blank in production. The resolution code that
builds repeater_info dropped latitude/longitude in every branch, so the
calculator could never find a coordinate. My tests passed hand-built
dicts straight to the calculator and never exercised the builder, which
is why they stayed green. Coordinates are now carried through all four
construction sites, and the new tests drive _lookup_repeater_names via
its lookup_func hook so the real builder runs.
- The #80 route guard was defeated two ways in the channel handler. When
the RF data was an uncorrelated fallback, control fell through to the
raw-hex and routing_info fallbacks below, which took the route from the
unrelated packet anyway; the guard had actually made that path
reachable. message.routing_info was also assigned unconditionally, and
the path command reads it. "Not attributable" is now a terminal branch
and the routing_info hand-off checks provenance.
- Same fix was incomplete for DMs: routing_info was captured and turned
into path_info before the provenance check ran, so the later check only
declined to overwrite an already-wrong value. Guarded at the source.
- Rendering could transmit for real. Capture only intercepts
send_response, but advert calls send_advert() directly and
send_response_chunked never checked capture_sink. Chunked sends are now
captured, and rendering is opt-in via BaseCommand.render_safe (default
False) instead of a denylist that cannot be complete. This also closes
the DM-only leak: schedule is not marked safe, so {cmd:schedule} can no
longer broadcast configuration to a channel.
- Multi-part rendered output was rejoined into one oversized send.
Scheduled messages are now split to the RF body budget and sent through
send_channel_messages_chunked, on character boundaries so multi-byte
text is not corrupted.
- _last_path_distance_km is instance state that was only set on success,
so an invalid path request could show the previous request's distance.
Reset at the start of every execute().
- Stale-contact retries were only counted on non-OK results, so timeouts
and exceptions left a contact eligible forever and could recreate the
storm. All failed attempts count now.
Web viewer:
- A failed config reload was reported as a successful save. The API and
UI now distinguish "saved and active" from "saved, restart needed".
- Preview count was unbounded; clamped to 1-20.
- update_ini_values is a read-modify-replace with no locking, so two
concurrent viewer saves could lose one. Serialised behind a lock.
Total path distance was already a solved problem here: the test command
computes it and exposes {path_distance} through the piped-template
engine, with pipe filters and docs. The path command just had no way to
reach it, since reply_prefix went through plain str.format.
Rather than add a second distance implementation, this reuses what
exists. BaseCommand.get_standard_placeholder_fields now returns the
shared placeholder set so subclasses can extend it, the path command
renders reply_prefix through format_piped_template with an added
{path_distance}, and the sum itself uses utils.calculate_distance over
the nodes the path command has already resolved.
Distance covers sender -> each hop -> bot and is deliberately blank when
the chain cannot be measured end to end (unresolved hop, prefix
collision, missing or 0,0 coordinates, unknown sender, no configured
bot position), so a partial sum is never reported as the real distance.
Because the prefix now supports pipe filters, an empty value takes its
label with it: {path_distance|prefix_if_nonempty:📏 }
Supersedes #198, which added a parallel haversine, a show_path_distance
flag, and a distance_traveled key across 10 locales.
