Icarus can now open Valorant match replays. A new Replays tab lists every match Valorant has downloaded. Opening one plays the match back on the Icarus map: each player's view cone is cut by walls, and utility, the spike, kills, health and armor, credits and weapons are all shown. Capture saves the moment on screen as a page of a strategy.

This replaces the Node prototype on codex/valorant-replay-file-reverse-engineering, which is left unmerged as the research record. That prototype only read build 13.00, took 30–300 s per match, and needed Node on the user's machine.

How it works

  • Decoding (native/replay, Rust, loaded over FFI like native/height). It is built on vrfkit v0.2.5 (Apache-2.0), which reads builds 11.06–13.06. Keeping up with new Valorant patches means bumping the vrfkit tag. A replay from a build vrfkit doesn't know is refused, never guessed. Why this route: docs/adr/0006-replay-decoder.md.
  • Oodle (native/replay/src/selkie.rs) is our own decoder, written clean-room. Every open-source Oodle decoder is GPL-3 or derived from it, including the ones labelled MIT. One agent wrote a facts-only spec from the format; a second agent, which never saw any ooz-derived code, implemented it from that spec. oozextract is not in Cargo.lock, and CI checks that.
  • The decoded replay is a versioned format holding Valorant facts only: subjects, agent UUIDs, class paths, game centimetres (docs/replay-format.md). Nothing in it names an Icarus type, so a future server can read it. It is a cache on disk, not part of the library.
  • Drawing. Each moment is built from the same PlacedWidgets a page holds and drawn with the editor's own read-only renderer (staticPlacedWidgetView, moved out of the transition overlay). Capture saves exactly what is on screen. Players keep their replay id on every captured page, so page transitions move them from one moment to the next.
  • Map projection. Uses the game-to-SVG alignment measured during the vision work. 99.6–99.9% of player positions land on walkable floor on all four maps the local replays cover. Cones also stand on the level the replay height puts each player on (e.g. under a roof rather than on it).

There was no replay UI on main before. The prototype's viewer never shipped.

Verification

  • Decoder, on all 7 local replays (build 13.00; Summit, Lotus ×2, Split ×2, Sunset ×2):
    • Decodes in 0.3–2.3 s.
    • Rounds, kills, plants, defuses and detonations equal the replay's Event chunks.
    • Movement record counts match vrfkit's own export exactly.
    • Score progression, sides per half and overtime, and team membership are all consistent; plants are by attackers, defuses by defenders, and no kill or assist is on a teammate.
    • Revives match vrfkit's export.
    • tests/corpus.rs pins all of this.
  • Selkie reproduces all 259 Oodle archives in the corpus byte for byte (931 MB at about 1 GB/s). The decoded replay is byte-identical to one decoded with the reference decoder. Malformed input is fuzzed and always returns an error, never a panic.
  • Dart:
    • 97 replay tests (reader, frame building, playback, capture against a real Hive box, files and cache, projection, ability catalog).
    • Full suite: 724 pass.
    • flutter analyze --no-fatal-infos is clean.
  • End to end: a widget test renders the real ReplayView against real replays through the production DLL. The screenshots above come from it. It also captures two moments and opens them in the real StrategyView.
  • Performance (profile build, 47-minute Split replay, round 3, 1× playback):
    • Opening the replay, decode included, takes 3.1–3.9 s.
    • Playback runs at 70+ fps: 60 fps steady on 60 Hz displays, and every other frame on 144 Hz.
    • With every cone recomputed every frame it was 46 fps. While playing, each frame now moves only the three players whose shown pose is oldest. Paused, scrubbed and captured moments are exact.
  • Windows build: flutter build windows puts icarus_replay.dll next to the exe. Release and Store builds package that same folder, and build_desktop_release.ps1 refuses an updater archive without the DLL. CI runs cargo test and clippy for the crate.

Known limits

  • macOS builds through native/replay/build_macos.sh (universal via lipo), but that is untested. Valorant only runs on Windows, so Mac users get replays they copy over.
  • Builds newer than 13.06 show as "Patch 13.xx" on the replay card until vrfkit registers them and we bump the tag. China-client replays use a different transform and are refused.
  • Archives over about 12.6 MB would use Oodle forms our corpus never contains, and fail as unsupported compression. The largest seen so far is 11.4 MB.
  • Breach's Fault Line draws at the default length. Its charged length fits 8 + 40 × charge m on the only two samples we have, which is too few to trust.
  • Untested maps: the 9 maps with no local replay use the same alignment pipeline but haven't been checked against a replay.

Follow-ups (not in this PR)

  • Vision height model (affects the editor too): Split's B heaven isn't modelled at 9 m, and automatic supports at 17–79 m exist on Lotus, Sunset and Summit. One support 37 m up is picked by default on ordinary Split floor.
  • Analytics: no replay events were added (docs/analytics.md keeps the set deliberately small). Captures count as strategy_created.

Summary by CodeRabbit

  • New Features
    • Added a Replays tab to the desktop library for importing replays, viewing match details and availability, and opening supported matches.
    • Added replay playback with map visualization, timeline and round controls, team perspectives, player stats, killfeed, and utility effects.
    • Capture replay moments as pages in a strategy and open them in the strategy editor.
    • Added replay discovery, decoding, and caching. Replay playback is available in the desktop app.
  • Documentation
    • Added replay terminology and documentation describing replay data and format.

RetriggerConfidence Score: 4/5

Not ready to merge: captures still lose smoke sight blocking, and two palette values still need to satisfy the repository's design requirement. The fallback-cone and same-name import concerns are non-blocking.

Findings

  1. P1 Capture loses smoke occlusion ▶
  2. P1 Captured smoke loses sight blocking ▶
  3. P2 Fallback ignores smoke occlusion ▶
  4. P2 Name the cone color ▶
  5. P2 Name the drop-overlay color ▶

Summary

The PR adds Valorant replay decoding, a replay library and viewer, and capture into strategy pages. The latest change reduces unnecessary native visibility rays and adds a curved-wall silhouette test. No new actionable finding was established. Previously reported problems with captured smoke, fallback cones, same-name imports, and palette values remain.

Written from a facts-only format spec; decodes all 259 archives in the
local replay corpus byte for byte at about 1 GB/s.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Reading: nullable facts stay null, non-finite numbers and malformed
buffers fail as bad format, every opening failure reaches the error
screen, cancel holds across awaits, one bad file never hides the list.

Playback: alive/dead follows whichever of round start, health and death
came last; quiet streams hold a living player in place; the dead stay
where they fell; speed carries fractional milliseconds; the score counts
the round being watched once it ends.

Capture: refuses non-finite frames before writing, starts a new strategy
if the old one was deleted or moved to another map, and Open lands on
the page just captured. The replay reclaims the editor's map and marker
settings when the user comes back from the editor.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Decodes all 7 local replays with no mismatch against the Event chunks
and the vrfkit oracle. Vitals fold round resets, damage, heals, deaths,
revives and armor items into a row per change; utility carries paths for
moving pawns and projectiles, Trapwire far ends, and wall points for Fast
Lane, Shear, Barrier Mesh and Blaze. Release and Store builds install
icarus_replay.dll beside the app and the updater archive refuses to ship
without it; CI runs the crate's tests and clippy.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Each player's view cone stands on the support level their replay height
puts them on (projection.visionElevationFor), so a player under a roof
sees from under it. While playing, a frame moves only the three players
whose pose is oldest (and any older than 66 ms): each move recomputes a
wall-cut cone, and ten in one frame held playback near 46 fps on a long
Split replay; three keep it at 70+ fps. Paused, scrubbed and captured
moments are exact. Size conversions the replay needs no longer depend
on a laid-out canvas.

Native:
- Cap file size, inflated data, schema groups and slots, retained records
  and output so a crafted replay is refused as corrupt instead of
  exhausting memory; the schema is checked before vrfkit allocates it.
- Progress and cancel go through a native control handle, so Dart never
  touches the atomics directly.
- quality.loss reports vrfkit's real loss counters.
- A repeated round reset no longer panics the decode; a dormant actor
  that wakes keeps one lifecycle; same-millisecond vitals follow wire
  order.
- Ship icarus_replay_NOTICE.md and the license beside the library.
- Pin Rust 1.96.1 and bootstrap it in CI and release builds; the cargo
  CI job gets a read-only token and no persisted credentials.

Dart:
- Parse decoded replays off the UI isolate.
- A probe player with no agent no longer fails the whole replay.
- Capture refuses non-finite rotation and lengths on every widget.
- The spike leaves the map when defused or detonated; players in Iso's
  off-map duel arena are not drawn or captured.
- Importing a different file of the same name replaces the kept copy.

A failed import no longer deletes the kept copy first: rename replaces it
atomically. The decoder version moves to 0.2.0 so caches decoded by
earlier builds of this change are rebuilt, and Cargo.toml says to bump it
whenever the output can change.

…65 Hz

Dara's notes from testing the viewer:

- Smokes block view cones. Every smoke (Omen, Brimstone, Clove, Jett,
  Miks, Astra, Viper's orb, Harbor's Cove, Cypher's cage) hides itself and
  the shadow behind it; Viper's Toxic Screen, Phoenix's Blaze and Harbor's
  High Tide hide what lies behind their line. Standing in a smoke, nothing
  shows.
- Thrown utility is shown in flight: its icon along the replay's path with
  a short trail (Omen and Jett smoke orbs, mollies, Sova's bolts, Fade's
  Seize, Reyna's Leer, Curveball and others), and a ring spreads where it
  activates.
- Utility that ends (destroyed, expired or popped) fades out where it
  stood with a burst, rather than vanishing. The replay does not say which.
- Ranges and areas players stand in are drawn at 30% so the agents and
  cones under them stay readable; smokes stay solid.
- Playback is smooth. Players moved a few at a time before (the cone cut
  was the cost); now every player moves every frame, moving utility glides
  between its 10 Hz path points, and cones are cut on a worker isolate
  (ReplayConeWorker) and drawn from their latest cut carried along with the
  agent, all in one layer clipped to the floor once (ReplayConesPainter).
  The roster, killfeed, dock and match card rebuild when what they show
  changes, and utility sits on its own cached layer.

Measured with the profile playback harness on Split: UI thread 3.0 ms and
raster 3.9-5.7 ms a frame (the window runs at its 144 Hz cap), from 13.5 ms
UI and 4.6 ms raster at 73 fps before.

The editor's view cone is unchanged apart from a hook that lets the replay
draw cones itself, and the height model's cone query is split so the
horizontal cut, which needs no dart:ui paths, can run off the root isolate.

Comment thread lib/replay/replay_cone_worker.dart
From Astra's review of the replay cones and effects:

- Smoke shadows are judged from where the agent stands now and erased in
  map space, so a smoke's shadow no longer slides or turns with a cone
  whose cut lags the agent by a frame.
- A wall's shadow closes along an arc past the cone's reach; a straight
  far edge between its ends cut back inside the reach when the wall was
  close, leaving what lay behind it visible.
- A cone whose cut was made from a point nudged out of wall ink is drawn
  with its apex on the agent, as the editor draws it.
- The cached utility layer follows the canvas size.
- A worker whose height models fail to load reports it instead of leaving
  the viewer waiting on it, and a failed cut is not asked for again in a
  loop; the frame is redrawn without it.

P1 Capture loses smoke occlusion

When active smoke blocks a player's sight, the replay cuts the view cone using this occluder, but Capture saves the player and smoke ability without preserving that sight block. Opening the captured page shows sight through the smoke instead of the moment shown in the replay.

Knowledge Base Used:

Artifacts

Focused smoke capture test source

  • The harness constructs a replay with active Omen smoke and captures a strategy page; its latest editor-cone revision has no confirmed execution result.

Passing replay-painter probe output

  • The executed Flutter test completed with exit code 0 and measured smoke-blocked versus blocker-free replay paint, establishing a narrower result than editor rendering.

P2 Fallback ignores smoke occlusion

While the cone worker is unavailable, agents draw their own cones without the frame's smoke occluders. An agent standing inside active smoke still shows a visible cone, temporarily misrepresenting what that player can see.

Knowledge Base Used: Ability vision boundaries

Artifacts

Executed fallback-smoke widget test source

  • This test mounts the replay canvas and captures its actual fallback cone painter before and during active smoke, providing the executable reproduction.

Fallback cone before smoke activates

  • The mounted cone painter was captured before the smoke spawned, showing the baseline visible sightline.

Fallback cone with smoke covering the agent

  • The same painter was captured with active smoke containing the cone apex; its pixels are unchanged, showing that smoke does not occlude the fallback sightline.

Flutter widget-test output for fallback smoke

  • The recorded command exited 0 and reported 1,031 painted cone pixels in both conditions, confirming the pixel-identical result.

P2 Name the cone color

The new replay painter hardcodes its cone color instead of naming the value in lib/const/settings.dart. This violates the design guide's single-source-of-truth requirement for palette values. The repository requirement must be satisfied before merging.

P1 Captured smoke loses sight blocking

  • Bug
    • A replay frame with active smoke paints zero cone alpha at and beyond the smoke, while the editor cone from the saved page paints alpha 81 and 58 at those points. The saved page therefore shows sight through smoke.
  • Cause
    • ReplayCapture saves the frame's agents and abilities without its occluders; SvgHeightViewConePainter has no smoke mask on the captured page.
  • Fix
    • Preserve active smoke occlusion for captured pages and apply it to the saved cone paint.

Three changes to the view-cone runtime, none of which change what a cone
covers:

- A vertex where touching pieces of one stroke meet, with the boundary
  running straight through it, is no visibility event. Skipping it drops
  35-65% of a cone's polygon points and 20-45% of its time (native and Dart
  alike); cone areas match the old ones to 1e-8.
- A ray aimed at an exact corner could land 1e-11 past both adjoining
  edges and run on to the range (9 of 485,570 vertex rays in an all-map
  audit). Endpoint slack is now 1e-10 SVG units along the wall instead of
  1e-12 of the edge, far below the 1e-8 radian rays that must pass a corner.
- Cones that overlook Lotus's and Icebox's measured floors no longer build
  their lit area with ~1,000 sequential path subtractions (160-190 ms per
  cone). The floor pass now returns its shadows as shapes, and painters
  fill each floor and erase them in a layer. The boolean area is kept, built
  only when the sightline report asks for it.

The floor pass no longer needs path operations, so the cone worker now
runs it after the horizontal cut and sends the floor layers back with the
polygon. Replay cones paint floors the way the editor does, in layers.

A cut was made for one facing and turned with the agent until the next
arrived, so a fast turn swung a stale cut through walls. Cuts now see all
the way round from where the agent stands, and the painter keeps the wedge
the agent faces. Turning never waits for a cut; only moving does.

- A shared edge cancels at a vertex only when the two walls lie on either
  side of it. Two walls over the same footprint, wound opposite ways, no
  longer lose their corners. Dart works out each edge's inside from its
  wall and hands it to native (ish_set_interior_sides); without it native
  skips no seams.
- Corner slack is 1e-13 + 1e-10 x the hit distance along the wall, so a
  ray 1e-8 radians beside a corner still passes it from a millimetre away.
- Floors are cleared and refilled without antialiasing, by the same pixel
  centres, so no faint seam is left along a floor edge inside a cone.

P2 Name the drop-overlay color

The replay drop overlay introduces Color.fromARGB(118, 2, 2, 2) directly in the widget instead of naming this new palette value in lib/const/settings.dart, as the design guide requires. This leaves the overlay outside the shared palette. The repository requirement must be satisfied before merging.

- An edge's side is taken only when a step either way tells inside from
  outside. A wall thinner than the step is "unknown" (2 in native), and no
  seam is skipped at its edges, so duplicated thin walls keep their corners.
- Floors are cleared and refilled with antialiasing, and the floor layer is
  added rather than laid over: at a floor edge on lit ground the cut keeps
  1 - c and the floor brings c, which sum to the fill. Edges facing open
  ground stay smooth.

A ray grazing a corner from within about 1e-5 SVG units of it is still
caught by the slack's 1e-13 floor; a smaller floor would let roundoff send
a corner-aimed ray through the wall, which is worse.

Merge note: once #238 is in, two tests in test/replay_map_projection_test.dart need updating. #238 makes Split's 36.5 m roof surface manual-only, so at (2548, -4509) the default level is already the 6.5 m floor. Split: under an automatic roof support, the floor should then expect no saved elevation (elevation returns null), and the defense side resolves the same level should drop that Split entry. I'll update them in whichever of the two PRs merges second.

A model may now list runtimeWalls: touching pieces with the same heights,
merged offline into one outline each. Cones and floor shadows are cast
against those outlines; the pieces stay the model for heights, standing and
ids. Merging cuts a map's cone edges about threefold and closes the hairline
cracks between pieces of one wall. The loader refuses a merge of pieces with
different heights, a piece in two merges, or a piece left out; without
runtimeWalls nothing changes.

…thing

A Lotus or Icebox cone built 900-2,200 shadow faces per frame, each a
rectangle clipped through lists and closures: 3 ms typical, 17 ms at p99 in
a profile-mode drag. Faces are now clipped in flat buffers, a face whose
wedge misses the floor is dropped before any clipping, and where a shadow
runs on for ever only the edges facing the eye cast it: an edge facing away
shades what the near side already shades. On 113 Lotus and Icebox cones the
shadows cover exactly the same 22,600 sample points, with 46% fewer faces
in a third of the time.

Where a merged outline cannot cover a piece's raw ring (a bow tie or a
sliver the union cleans away), the model lists that ring as extra edges
under the piece's heights, so a cone stops where the pieces stopped it.

A bow tie's crossing edges change side along their length, so the side a
midpoint probe found let floor shadows cull both diagonals and leave the
lobe behind them lit. Edges something crosses or meets inside their
length are now unknown, which only costs a seam or a shadow face; along a
run of a ring that nothing else comes near the side cannot change, so one
probe answers for the run. Cone edges and floor shadows share the answer,
computed once per runtime wall at load instead of per edge on the first
floor frame (Lotus: about 20 ms against 360 ms in a debug test).

Runtime edges carried under a piece's heights may no longer also name
members, which the loader ignored.

The caller waits for every chunk of a query, so a pool thread the
scheduler sets aside for a 15 ms time slice while holding one stalled the
drag. On a desktop busy with other work (12 busy processes on 16 cores) a
sweep of 16,000 Summit queries had p99 6.6 ms and a 163 ms worst case;
with the calling thread raised for the query and the workers raised for
good (they sleep when idle), p99 is 2.6 ms and the worst 5.5 ms. A quiet
machine is unchanged (p99 1.9 ms).

Every vertex in reach cast three rays: at it and just beside it on each
side, so that a wall turning away there lets the ray past it find what is
behind. Where the vertex's two active edges leave to either side of the
ray, the wall runs across it and the rays beside it only meet those two
edges. Curved walls flattened into centimetre edges are made of such
vertices. Cones keep their exact area (to 1e-9 against the Dart query on
1,200 Pearl, Summit and Lotus defense cones) with half the points; the
Pearl defense sweep's p99 goes from 6.5 ms to 5.1 ms.
