Oversteer 0.14.0

Added

• Rev lights: Learn the limiter at each launch. A rally stage starts
  with clutch in, handbrake up and the throttle floored, which holds the
  engine on its limiter; Oversteer learns that RPM at every standing
  launch and the % shift point applies to it, so each car on each stage
  gets its own shift light even when the game reports no maximum or the
  wrong one. It is raised if the car is later held on a higher limiter
  flat out (a launch control capping the revs at the line), never by a
  moment past it, and forgotten when the telemetry stops between stages.
  With no handbrake fitted, clutch in and throttle floored is the launch.
• Rev lights: Shift lights at the learnt best upshift for each gear:
  once Oversteer knows the car's power curve and gearing, the lights
  complete where the next gear starts pulling harder; a gear that pulls
  to the limiter still flashes as it gets there.
• Telemetry tab: the shift table has a column per way of changing gear
  (H-pattern, sequential, paddles) once you have used it. How each change
  was made comes from the control you pressed: a shifter gear, the
  sequential plate or a paddle.
• EA SPORTS WRC telemetry: the game's default structure, or Oversteer's own
  (car and stage ids, session start/end/pause), set up with two Copy
  buttons under the Telemetry tab's Settings.
• scripts/telemetry-capture.py --write records raw telemetry to a file;
  scripts/telemetry-replay.py plays it back through the shift learner,
  re-sends it over UDP, or cuts a piece out of it.
• Telemetry history: every drive is kept as runs (a stage attempt, a lap
  session, a stretch of free driving) with their corners, a 10 Hz trace
  and every change of gear up or down, flagged when a gate was missed,
  a gear skipped, the engine over-revved or a paddle double-tapped. Each
  run is judged a discipline (rally stage, hillclimb, circuit,
  rallycross, time attack, free roam) with the evidence that decided it,
  or left unknown when there is none. Each gearing a car was driven with
  is kept as a tune.
• Coaching from that history in the Telemetry tab: what the last session
  was and why Oversteer thinks so, the habit to work on first, up to
  three tips with their numbers (changing up early or late per gear and
  way of changing, the limiter, missed gates and double taps, bogged
  launches, both pedals at once on tarmac, coasting and corners against
  your best run of a stage) and praise when a habit improves. A tip
  shown on two occasions (hours apart) goes quiet until it gets worse. Changing up early waits
  until the surface is known, since short-shifting on gravel can be
  right.
• Tuning advice from the runs on the car's current setup: a final drive
  too short or too long for a stage, a gear too long out of corners, and
  oversteer or understeer fitted to how you drive, always "if the setup
  allows" and with the driving alternative first.
• "Label last session…" in the Telemetry tab: say what a session was
  (discipline, surface, wet, shifter), for Oversteer to learn surfaces
  from.
• A read-only web page for a phone or another computer (off by default,
  TCP 5301, under the Telemetry tab's Settings): the live gear and revs
  against the shift point, the shift tables, coaching, setup advice and
  recent sessions with their evidence. Nothing can be changed from it;
  anyone on the same network can read it, so it can be limited to this
  computer. Clients with a public address are refused.
• "Learn from game telemetry": learn shift points and keep the history
  with the rev lights off, or with a wheel that has none.
• "Record raw telemetry" under the Telemetry tab's Settings (off by
  default): what the game sends is kept as it arrived, a file per drive,
  in Oversteer's data folder, up to a size you choose (1 GB by default;
  the oldest go first). Labelling a session also labels its captures and
  keeps them.
• Telemetry tab: the best upshift of each gear shows the range it is
  known to.
• Stage tables for WRC Generations (all 21 rallies, 165 stages), Assetto
  Corsa Rally (46 stages to update 0.6) and DiRT Rally 2.0 (every rally
  stage, rallycross track and DirtFish): a run on a known stage has its
  name, rally and surface from the first drive, without labelling. The
  WRC Generations and Assetto Corsa Rally tables come from the games'
  own data (exact lengths, names, surface shares); WRC Generations sends
  each stage's exact length, which identifies it, stage and reverse
  alike. DiRT Rally 2.0's data is encrypted: its table is the community
  one, checked against the game's stage counts.
• The Assetto Corsa family bridge (oversteer-run) sends more: the
  stage's length and the progress along it, wheel speeds, suspension
  travel and the game's current rev limit. OVERSTEER_BRIDGE_VERBOSE=1
  in a game's launch options logs the rest once a second, for checking a
  game's layout.
• Oversteer reopens the profile last used when it starts (unless
  --profile or a setting on the command line says otherwise): cars
  and history are kept per profile, and starting on none showed an
  empty Telemetry tab.

Changed

• Profiles saved before this version get both new rev light switches
  (the launch limiter, the learnt upshifts) turned on, as new profiles
  do: the lights then follow the car rather than the fixed percentage.
  Untick them under the Telemetry tab's Settings for the old behaviour.
  A profile that never stored a shift point keeps 97 %; new ones start
  at 95 %.
• The shift learner compares each gear's own power curve where it knows
  both, takes the slope out of the acceleration where the game says
  which way is up, ignores turbo lag and wheelspin, and gives each best
  change up a range. Its database moves to a new layout (a copy of the
  old file is kept as telemetry.db.v1.bak), and writing it no longer
  happens on the telemetry thread.
• A driving session now ends after two minutes without telemetry, not
  two seconds, so pausing mid-stage no longer splits it. Forgetting a car
  starts its learning over but keeps its history.
• The telemetry port is now UDP 5310 for new profiles and
  oversteer-run. Forza Horizon 6 binds its own socket in 5200–5300 and
  asks Data Out to stay clear of that range. Profiles that saved 5300 keep
  it. When nothing arrives, Oversteer listens on the other port for a
  second now and then and says so if a game is sending there.
• The listener takes telemetry from one source at a time (the first one
  heard, until it goes quiet), so a bridge left running next to a game
  no longer mixes two cars.
• The Telemetry tab is laid out like the other tabs, in two views.
  Car and coaching: the car, a one-line live status with a coloured
  dot, the shift points in a framed table (the best upshift in bold),
  coaching one row per tip with a Focus / Tip / Better tag, the last
  session with "Why Oversteer thinks so" and "Label…", recent sessions
  one row each, the setup. Settings: framed lists for receiving
  telemetry, the rev lights (no longer one crowded row), the web page
  and recording, each row a title with a short explanation or its status
  under it.
• The web page is a dark live dashboard for a phone or laptop next to
  the rig: shift lights, the gear huge, speed, rpm, where to change up in
  this gear and the stage by name with its progress, updated four times
  a second; then coaching, the shift points with the current gear
  highlighted, the setup and recent sessions. It fits portrait and
  landscape phones and puts the live panel beside the rest on a laptop.
  It keeps the screen on: with the browser's wake lock where allowed
  (HTTPS or the same computer), otherwise after a first tap with a tiny
  muted video made in the page. A chip at the top says whether the screen
  is being kept on.

Fixed

• Telemetry packets arriving in a burst, or a reset after a crash, were
  taken for a teleport and split one stage into several runs.
• WRC Generations sends its stage's length where DiRT sends progress: it
  was read as progress, so no stage finished.
• DiRT Rally 2.0 (and DiRT Rally, DiRT 4): engine rpm was read 4.7 % too
  high (the game sends rad/s, not rpm / 10), and with it the shift light
  and everything learnt. Cars already learnt are corrected once when the
  telemetry database opens (a backup is kept as telemetry.db.v0.bak).
• Reverse in DiRT Rally and WRC Generations, and neutral in Forza, were
  read as "unknown gear"; H-pattern changes through neutral are now seen
  in Forza Horizon.
• Gear ratios are learnt only at part throttle, where the tyres barely
  slip: a first run spinning up gravel no longer leaves a car with wrong
  ratios and a false "re-tuned" note.
