Adds Microwaveprop.Radio.TextSanitizer to remove BOM, zero-width
spaces/joiners, C0 control bytes (except CR/LF/TAB), and DEL, and to
collapse NBSP and other unicode whitespace into a regular space.
CSV: applied to the whole upload at the top of preview/2.
ADIF: applied per-field-value after extraction so the byte-counted
length tags still slice the right substring.
ADIF records frequently include operator commentary in the
<NOTES> field (multi-line, detailed) or <COMMENT> (short
one-liner). Now that contacts have a notes column, pass that
value through the import pipeline instead of dropping it.
Preference is NOTES over COMMENT to match the ADIF 3.1.4 spec's
intended split — NOTES is the richer field. Whitespace-only
values collapse to nil so a program that always emits a blank
NOTES tag doesn't fill every row with an empty string.
Tests cover NOTES capture, COMMENT fallback, NOTES-over-COMMENT
preference, and the absent-field nil case. ADIF upload blurb
lists the new carry-over so users see it before confirming.
Classifies every contact's likely non-LOS propagation mechanism and
persists the result on contacts.propagation_mechanism. Mechanism is
determined in priority order:
1. user_declared_prop_mode (ADIF PROP_MODE from the operator log)
2. EME — moon-ephemeris check, ≥2m band, >1800 km path
3. aurora — Kp≥5 + high-lat path, 50-432 MHz
4. sporadic-E — foEs × 5 ≥ band_mhz, 400-2500 km path
5. meteor_scatter — ±3 days of a shower peak, VHF/UHF
6. rain_scatter — common-volume radar heavy rain, 5-11 GHz ≤800 km
7. tropo_duct — HRRR native_best_duct ≥ band or ducting_detected
8. line_of_sight — ≤50 km path
9. troposcatter — default
Persisted via MechanismClassifyWorker (queue: :mechanism, unique on
contact_id). Submit-time enqueue path includes :mechanism by default;
BackfillEnqueueWorker cron now handles :mechanism alongside existing
types so prod continuously backfills any contact with
propagation_mechanism_status in (:pending, :queued, :failed). Also
added :radar to the cron's type list so common-volume radar backfill
runs automatically rather than only via `mix radar_backfill`.
New modules:
- Microwaveprop.Propagation.MoonEphemeris — Meeus low-precision moon
position, accuracy ±1° — enough for the mutual-visibility EME test
- Microwaveprop.Propagation.MechanismClassifier — plug-in priority
chain over the evidence map
- Microwaveprop.Workers.MechanismClassifyWorker — assembles inputs
from HRRR / native profiles / common-volume radar / solar_indices /
ionosonde + calls the classifier
ADIF importer now reads PROP_MODE into user_declared_prop_mode so
operator-tagged mechanisms (EME/ES/MS/RS/AS/AUR) become ground truth.
Widen dedup match to 4-char grid prefix so an upload with a longer grid
(e.g. FN42aa25) finds the existing FN42 contact. Within a match, classify
as a refinement when the upload strictly extends the existing grid or
fills a missing mode; as a contradiction (still skipped) when grids or
modes genuinely disagree. Refinements flow through a new preview bucket,
update the existing row in place, and re-enqueue enrichment when the
position changed.
Profile page:
* New MicrowavepropWeb.UserProfileLive at /u/:callsign is a public
page showing a user's contacts and beacons. Resolves case-
insensitively so /u/w5isp and /u/W5ISP are the same thing; unknown
callsigns redirect to /. Uses daisyUI card / stats / table
components with an avatar-placeholder initial and hero icons.
* Accounts.get_user_by_callsign/1 (case-insensitive) plus
Radio.list_contacts_for_user/1 and Beacons.list_beacons_for_user/1
back the page. Beacons list includes both approved and pending so
owners see their drafts.
* The top nav bar and the three LiveView sidebars (MapLive,
WeatherMapLive, ContactMapLive) now render the logged-in callsign
as a navigate link to /u/:callsign instead of a static label.
* Nine new tests cover the lookup, the LiveView render, and the
ownership-scoped queries.
Flexible band input:
* New Microwaveprop.Radio.BandResolver module converts any of:
ADIF wavelength labels ("33cm", "1.25cm", "6mm", case/whitespace
insensitive), numeric frequency strings ("903.100", "10368.000"),
and canonical MHz integers into the one of the site's known bands.
Returns the nearest allowed band for numeric inputs >= 900 MHz,
nil otherwise.
* 902 MHz is added to Contact.@allowed_bands, ContactEdit.@allowed_bands,
AdifImport.@allowed_bands, and the BandResolver list so "33cm"
round-trips end-to-end.
* AdifImport and CsvImport now delegate band resolution to
BandResolver, and Radio.create_contact/2 normalizes the :band attr
on the way in so the manual form and any API callers benefit too.
CsvImport's "invalid band" tests previously used 99999 MHz which
the new resolver snaps to the nearest allowed band; swapped to
"notaband" which is truly unresolvable.
Contacts and beacons list UX:
* Remove the "Submitted" column from /contacts — it duplicated info
already visible on the detail page and was pushing the real
columns off narrow viewports. submitted_cell/1 and its three
column-specific tests go with it.
* Hide the Lat / Lon columns from /beacons — six decimal places of
coordinates weren't useful next to the grid square and took a
disproportionate amount of row width.
Regex.scan with `return: :index` reports BYTE offsets, but String.slice/3
uses CHARACTER offsets. When a record contained a multi-byte UTF-8
character in an earlier field (e.g. "café" in NOTES), every subsequent
field's slice shifted one byte left, eventually landing on a literal
">" that crashed String.to_integer/1 with ArgumentError.
Switch to :binary.part/3 which is byte-based and matches what Regex.scan
reports. Also simplify the value offset calculation to use the scanned
tag_len directly instead of re-splitting the tag text. Reproduced in a
new regression test.
Prod stack trace: AdifImport.parse_fields/1 crashed on upload with
binary_to_integer(">") -- a FreeDV/N1MM logger that embedded UTF-8
characters in a NOTES field triggered it.
- AdifImport.normalize_mode/2 maps ADIF MODE (and SUBMODE when present)
onto the fixed set of modes the site accepts: CW/SSB/FM/FT8/FT4/Q65.
SUBMODE takes precedence so `MODE=MFSK, SUBMODE=FT8` correctly imports
as FT8. USB/LSB/DSB all become SSB; NBFM/WFM become FM.
- Unknown modes (RTTY, PSK31, etc.) map to nil so the row still imports
— mode is optional on the submission path now.
- AdifImport.mode_mapping_reference/0 returns the user-facing list of
recognized inputs and their mappings.
- Submit page's ADIF tab renders that list in a table so users can see
upfront what will happen to their file before uploading.
- Add belongs_to :user on Beacon schema, preload in get_beacon!/1
- Show "Submitted by {callsign}" on beacon detail page
- Add NTMS donation link on the about page
- Change grid preference text to 8 characters (e.g. EM12kp37)
Parse ADIF tagged-data format with fuzzy frequency-to-band matching
(nearest microwave band for any freq >= 900 MHz). Supports STATION_CALLSIGN,
OPERATOR, CALL, GRIDSQUARE, MY_GRIDSQUARE, FREQ, BAND, QSO_DATE, TIME_ON.
Same dedup and preview/commit flow as CSV upload.
Also fix select dropdown text alignment in daisyUI.
