AGENTS.md

This file provides guidance to coding agents working in this repository.

Plan Mode

• When an agent is in Plan Mode and produces a final <proposed_plan>, it must also save that finalized plan as a Markdown file in the repo-root .plans/ directory.
• Save only finalized plans. Do not write interim exploration, questions, or draft revisions to .plans/.
• Use the filename pattern YYYY-MM-DD-short-topic.md such as .plans/2026-03-12-channel-filtering.md.
• If the intended filename already exists, append a numeric suffix such as -2, -3, and so on.

Agent Bootstrap

• In a fresh worktree, run pnpm install --frozen-lockfile before relying on Nx project discovery, lint, test, or build commands. Without node_modules, pnpm nx show projects will fail because the local Nx modules are unavailable.
• After dependencies are installed, verify workspace discovery with pnpm nx show projects.
• Use scoped path aliases from tsconfig.base.json such as @iptvnator/services, @iptvnator/shared/interfaces, and @iptvnator/ui/components. Do not add new imports from legacy bare aliases such as services, shared-interfaces, components, m3u-state, or database.
• Every Nx project should keep scope:*, domain:*, and type:* tags in project.json so @nx/enforce-module-boundaries remains useful for humans and agents.
• See docs/architecture/nx-workspace-boundaries.md for the current Nx tag and alias policy.
• Repository-specific skills are committed under .codex/skills/. Claude Code only discovers skills under .claude/skills/, so release-notes and release-cut are mirrored there and the two copies must be kept in sync; every other entry in .claude/skills/ is personal and stays gitignored. If an external agent does not support skills, treat those files as concise ownership docs.

Documentation After Changes

• After implementing a meaningful change, agents must assess whether canonical repo docs need updates before considering the task complete.
• Meaningful changes include new or changed user-visible behavior, architecture or data-flow changes, non-obvious maintenance workflows, new setup/debugging steps, and new subsystem contracts or boundaries.
• Skip doc updates for trivial refactors with unchanged behavior, formatting-only edits, and isolated test-only changes.
• Prefer updating an existing authoritative doc before creating a new one:
  1. README.md for top-level developer or user workflows
  2. docs/architecture/ for architecture, ownership, and behavior contracts
  3. the nearest module README.md for local usage or behavior
• Keep the root CLAUDE.md and this file up to date. They are living documents: whenever a change touches something they describe — monorepo structure (new/moved/renamed apps or libs), routes, database schema/tables, stores and their features, key components, commands, environment behavior, or coding conventions — update the affected sections as part of the same task, and keep the process sections mirrored between AGENTS.md and CLAUDE.md in sync.
• When adding a new feature area, check whether the Architecture or Key Features sections of CLAUDE.md describe the surrounding area; if they do, reflect the addition there instead of leaving the description stale.
• Do not let CLAUDE.md or AGENTS.md drift: a stale path or route in these files poisons the context of every future agent session. If you notice an outdated claim while working, fix it (or flag it in the final summary) even if it is unrelated to the current task.
• Repo docs are canonical even when they were originally drafted by an LLM.
• Final task summaries should state whether docs were updated and which doc changed.

Release Notes For User-Visible Changes

• Any change a user could notice — new behavior, changed behavior, bug fix, performance win, breaking change — must add one note file under .changes/ in the same PR. Format, field table, and writing rules: .changes/README.md.
• Name it <area>-<short-slug>.md; area matches the conventional-commit scope. There is no version field — the release version is chosen at release time.
• Write the body for a user, not a reviewer: "the player now remembers volume between episodes", not "hoist volume state into the session". Max 400 characters; depth belongs in the release blog post.
• Skip the note for test-only changes, docs, CI/workflow plumbing, and pure refactors with no behavior change. When skipping on a PR that touches apps/** or libs/**, apply the no-release-note label.
• CI enforces this: the "Release note gate" job in .github/workflows/ci.yml fails PRs that change runtime code without an added .changes/*.md or the label (policy in tools/release/check-release-note-gate.mjs; tests/e2e/website/mock-server/docs paths are auto-exempt).
• The release-notes skill covers writing notes; the release-cut skill covers the full release sequence.
• Validate before finishing: pnpm run release:notes:validate.
• Release-post screenshots come only from the release capture script running against the mock servers. Never add a screenshot taken from a real playlist or account to apps/website/public/blog/** — real streams, logos, and metadata are copyrighted, and credentials must never reach a published image.
• Final task summaries should state whether a release note was added or why it was skipped.

Regression Prevention And Test Updates

• Before the final summary for any feature, behavior change, bug fix, data-flow change, Electron IPC/database change, or user-visible UI workflow change, complete a test impact pass. Identify the affected projects and decide whether unit, integration, E2E, build, lint, or manual/CDP verification is required.
• Bug fixes must normally include regression coverage that fails on the old behavior and passes with the fix. If automated coverage is not practical, document why in the final summary and include the strongest manual validation performed.
• Feature work and behavior changes must update existing tests when assertions, fixtures, mocks, routes, or E2E flows are now stale, incomplete, or missing. Prefer extending the closest existing spec or E2E file before adding a new suite.
• Default validation ladder:
  1. Run targeted unit tests for directly affected projects with pnpm nx test <project> or existing scripts such as pnpm run test:frontend, pnpm run test:backend, or pnpm run test:unit:ci when the scope is broader.
  2. Run affected E2E coverage when changing user-visible workflows, routing, persistence, playback, portals, settings, import flows, or Electron-only behavior.
  3. Use pnpm nx show projects --withTarget test and pnpm nx show projects --withTarget e2e when project ownership or available validation targets are unclear.
  4. Prefer specific atomized E2E targets before broad suites when they cover the changed behavior, for example pnpm nx run web-e2e:e2e-ci--src/xtream.e2e.ts or pnpm nx run electron-backend-e2e:e2e-ci--src/search.e2e.ts.
• Electron-specific changes affecting IPC, SQLite, packaged runtime, external players, native file access, or Electron-only routes require Electron E2E coverage where available, or CDP/manual verification with agent-browser and the tracing flags documented below.
• Final task summaries must list tests added or updated, validation commands run with results, and any skipped validation with the reason. For docs-only changes, state that unit/E2E validation was not required and verify the changed Markdown instead.

Electron Debugging (CDP)

• Start the Electron development app with: nx serve electron-backend
• Package-script equivalent: pnpm run serve:backend
• Electron is configured to start with: --remote-debugging-port=9222
• Connect Chrome DevTools Protocol tools to: 127.0.0.1:9222
• For Electron automation/debugging tasks, use the electron skill
• Do not auto-open DevTools during normal CDP automation. In development, DevTools is opt-in via ELECTRON_OPEN_DEVTOOLS=1.
• If DevTools is open, agent-browser --cdp 9222 ... may attach to the DevTools page instead of the IPTVnator window. Symptoms: tab list shows about:blank, snapshots are empty, and screenshots are black.
• If that happens, inspect targets with curl http://127.0.0.1:9222/json/list and connect directly to the IPTVnator page websocket from the webSocketDebuggerUrl field.

Trace / Debug Startup

• Full startup tracing:

IPTVNATOR_TRACE_STARTUP=1 nx serve electron-backend

• Narrower trace flags:

  • IPTVNATOR_TRACE_IPC=1 traces renderer window.electron.* bridge calls
  • IPTVNATOR_TRACE_DB=1 traces DB worker requests and request-scoped DB events
  • IPTVNATOR_TRACE_SQL=1 traces SQLite statements in the main process and DB worker
  • IPTVNATOR_TRACE_WINDOW=1 traces BrowserWindow lifecycle and unresponsive events
  • IPTVNATOR_TRACE_PLAYER=1 traces external-player activity and bounded Embedded MPV runtime-probe stderr
  • IPTVNATOR_TRACE_RENDERER_CONSOLE=1 mirrors renderer console output into the Electron terminal

• Settings, portal request/response, and trace payloads must use @iptvnator/shared/logging or the redacting portal logger before reaching console.*; never log raw credentials while debugging.

• If local Nx state gets weird before a rerun:

pnpm nx reset

agent-browser (global install)

Radio / Audio Player

M3U playlists can contain radio channels identified by the radio="true" attribute on #EXTINF lines. When a radio channel is selected:

• The dedicated AudioPlayerComponent (libs/ui/playback/src/lib/audio-player/) renders instead of a video player
• The audio player always uses the built-in inline player — external player settings (MPV/VLC) are ignored
• The EPG panel is hidden (radio streams have no EPG data)
• The layout uses a cinematic hero pattern: the station logo is blurred as a full-area backdrop with a vignette overlay, and the artwork card + controls float above it
• Volume is shared with the video player via localStorage key 'volume'
• Keyboard shortcuts: ArrowUp/ArrowDown (volume +/-5%), M (mute toggle)
• Radio detection in the video player template: activeChannel.radio === 'true' — this is a string comparison, not boolean

Key files:

• libs/ui/playback/src/lib/audio-player/audio-player.component.ts — the audio player component
• libs/ui/playback/src/lib/audio-player/audio-player.component.scss — cinematic hero styling
• libs/playlist/m3u/feature-player/src/lib/video-player/video-player.component.html — template conditionals for radio vs video
• libs/shared/interfaces/src/lib/channel.interface.ts — radio: string field on Channel interface

Shared Player Controls

• libs/ui/playback/src/lib/player-controls/ contains the additive, engine-neutral PlayerController contract, standalone app-player-controls, generic web-video adapter/helper, and component-scoped WEB_PLAYER_SHARED_CONTROLS rollout token.
• In fullscreen, app-player-controls shows a pointer-transparent media-title overlay at the top while controls are revealed (mediaTitle input: movie/channel/series name, plus an S01E03 second line for episodes). Series names flow from the Xtream/Stalker detail views through PortalInlinePlayerComponent.seriesTitle and WebPlayerViewComponent.mediaTitle; movie and live hosts fall back to playback.title, skipping raw stream-URL fallbacks. Outside fullscreen the overlay stays hidden.
• Persisted Settings.webPlayerSharedControls is default-off, and its checkbox appears only when HTML5, Video.js, or ArtPlayer is selected. WebPlayerViewComponent snapshots the preference into WEB_PLAYER_SHARED_CONTROLS for each new player host. The parent /workspace route awaits the initial SettingsStore load, including cold-start direct links, before this snapshot can occur. Saving applies to the next host without an application restart; an existing session never changes controls mode in place.
• Embedded MPV ignores the web-player preference. Frame-copy always uses shared DOM controls through its component-scoped EmbeddedMpvControlsAdapter, while native-view retains the legacy compositor-safe dock and external MPV/VLC retain their own UI. The host must render exactly one controls system for the reported Embedded MPV engine.
• Frame-copy shared controls own DOM surface interactions, shortcuts, fullscreen, and recording feedback. showControls=false detaches the shared surface, modal overlays gate playback shortcuts, fullscreen still triggers bounds sync, and a playback/session transition key prevents engine or session handoff from presenting stale recording feedback while timers and pending commands are cancelled. Same-session IPC replies also yield to a broadcast snapshot received while the command was pending, preventing a successful recording acknowledgement from being rolled back by a stale reply.
• DASH (.mpd) sources play through a lazily imported Shaka Player source engine (libs/ui/playback/src/lib/shaka-engine/) inside the HTML5 and ArtPlayer components; ClearKey keys come from KODIPROP-derived Channel.drm, and the shared bridge exposes Shaka audio/text tracks via source kind shaka. See the CLAUDE.md "Video Players" feature entry and docs/architecture/m3u-playlist-module.md ("DASH + ClearKey Playback").
• The built-in HTML5/hls.js player is the second guarded consumer. HtmlVideoPlayerComponent provides a component-scoped WebVideoControlsAdapter; its neutral web-video-support bridge is shared with ArtPlayer and owns HLS/Shaka(DASH)/native tracks, MPEG-TS VOD duration correction, caption preference, and source cleanup. HtmlVideoElementSession owns native video-event lifecycle, persisted volume, start-time/time/ended propagation, and legacy post-play caption suppression. WebPlayerViewComponent.resolvedIsLive supplies authoritative live/VOD metadata, while a visible playback diagnostic disables both shared surface interaction and shortcuts and exits the HTML5 shell's own fullscreen so the diagnostic actions remain visible. The preference-off path keeps native controls and legacy series navigation unchanged.
• Video.js is the third guarded consumer. VjsPlayerComponent provides a component-scoped WebVideoControlsAdapter; its bridge binds the current Tech video, rebinds after playerreset, exposes source-stable audio/subtitle IDs, preserves caption preference and explicit subtitle-off state, and reads duration from Video.js. Reset-driven raw MPEG-TS changes pause first, coalesce to the latest desired source, preserve actual volume across Video.js's reset, and restart when authoritative live/VOD metadata changes. The shared-controls path disables native controls, Video.js click/double-click/hotkey actions, and spatial navigation; diagnostic gating and owned-fullscreen exit match HTML5. The preference-off path keeps the existing Video.js skin and legacy series navigation unchanged.
• ArtPlayer is the fourth guarded consumer. ArtPlayerComponent provides a component-scoped WebVideoControlsAdapter; ArtPlayerSourceSession owns HLS/DASH(Shaka)/MPEG-TS/native sources, the neutral web-video bridge, exact cleanup, and a destroyed-session guard for delayed customType callbacks, while ArtPlayerVideoSession owns native media/ArtPlayer events. Shared mode uses authoritative live/VOD metadata, HLS/Shaka/native tracks and caption preference, MPEG-TS VOD duration correction, and reapplies app volume directly after ArtPlayer restores its own stored volume. Vendor chrome/hotkeys are disabled, and a transparent capture layer gives shared controls exclusive click and double-click ownership. Diagnostic interaction gating and owned-fullscreen exit match the other web players. The preference-off path keeps the legacy ArtPlayer skin, source behavior, and series navigation unchanged.
• Shared web picture-in-picture stays inside that default-off rollout. PlayerController exposes capability pictureInPicture, state pictureInPictureActive/canPictureInPicture, and command togglePictureInPicture(). HTML5, Video.js, and ArtPlayer use standard element PiP from the adapter's attached video; shared ArtPlayer keeps vendor pip: false, while preference-off native/vendor paths remain unchanged. The capability-gated button sits before fullscreen and uses active enter/exit semantics; entry is disabled until metadata, and the action is disabled while an operation is pending. Embedded MPV reports capability/state false with a no-op command and has no popup/mini-window.
• WebVideoControlsAdapter supplies its current video and binding generation to WebVideoPictureInPictureController; the controller reads the video's ownerDocument, while browser enter/leave events remain authoritative. Exact-owner exit stays available if request support changes. Request/exit invocation remains synchronous for user activation, one operation is serialized, and binding generation plus exact video identity protects replacement and teardown from stale completion. Video.js Tech reset and ArtPlayer rebuild rebind with exact-owner cleanup; HTML5 source changes on a retained target preserve PiP. Standard PiP shows the browser/OS video surface without Angular control chrome, with browser-dependent subtitles. AirPlay, Cast, Document PiP, a PiP keyboard shortcut, and Embedded MPV popup/native support are out of scope.

Linux Embedded MPV Packaging

• Official Linux frame-copy artifacts are x64-only. AppImage, DEB, RPM, Pacman, Snap, and Flatpak are supported; non-x64 Linux packages must remain marker-only and must never inherit x64 native artifacts from environment overrides.
• Packaging runs three isolated profiles:
  • system: DEB/RPM/Pacman, no private native/lib, with package dependencies DEB=libmpv2,libegl1,libgl1,libgbm1, RPM=mpv-libs,libglvnd-egl,libglvnd-glx,mesa-libgbm, and Pacman=mpv,libglvnd,mesa
  • portable: AppImage/Snap with the pinned LGPL-compatible closure
  • flatpak: Flatpak with the same pinned closure
• Flatpak is an isolated packaging pass and keeps iptvnator as the real Electron ELF so Electron Builder's electron-wrapper passes it directly to Zypak. Other Linux targets retain the conditional iptvnator wrapper and iptvnator.bin. Mixed Flatpak/non-Flatpak target sets fail before mutation.
• The DEB system-runtime contract is Ubuntu 24.04+ (libmpv2). Ubuntu 22.04 provides libmpv1, so use the x64 AppImage on Jammy instead of weakening the package dependency or advertising frame-copy without a compatible runtime.
• Only iptvnator_mpv_helper may link libmpv. The Electron executable, Electron libraries, embedded_mpv.node, and embedded_mpv_frame_reader.node must not load or link it. Preserve this process-isolation contract in build, package, and smoke checks.
• electron-backend/native{,/**/*} is excluded from app.asar; afterPack exclusively writes the profile-normalized unpacked native tree. Layout and final-artifact checks must reject every archived /electron-backend/native/** entry so system and marker-only packages cannot hide stale x64 artifacts.
• Packaged addon, frame-reader, and helper discovery is package-owned app.asar.unpacked only. Writable cwd/dist candidates are development-only and must never satisfy packaged native-view support or the frame-copy gate.
• Pristine afterPack/unpacked layouts scan Electron libraries recursively. Extracted Snap payloads exclude only the package-manager lib/** and usr/lib/** trees that Snap overlays into the same root; every other directory remains recursive, and Electron-library symlinks still fail closed.
• Linux frame-copy availability is fail-closed. The packaged manifest, artifact modes, declared bundled hashes/closure, and bounded --runtime-probe must all succeed before frame-copy can relax the renderer sandbox. Any failure reports a stable reason and falls back to native-view without crashing; an environment flag never bypasses this gate.
• Snap is core22/strict and uses an exact private shared-memory plug plus the graphics-core22 content plug at an empty mode-0755 $SNAP/graphics, with mesa-core22 as default provider. It declares only the canonical provider layouts: /usr/share/libdrm binds from $SNAP/graphics/libdrm, and /usr/share/drirc.d symlinks to $SNAP/graphics/drirc.d. The provider is external shared content, not part of IPTVnator's package size, source archive, or notices. Installed-Snap CI must prove controlled unavailable exit after disconnect, then reconnect and prove success. The helper links libGL.so.1 rather than libOpenGL.so.0.
• The probe and playback helper share one sanitized loader environment: ambient audit, preload, library, graphics-driver, and shell-startup overrides are removed; the validated private closure wins; trusted Snap GL, graphics-core22, the core22 base x64 root, and exact GNOME-platform roots precede generic in-snap roots. The core22 base must precede GNOME so its libedit.so.2 cannot be replaced by the older copy requiring libtinfo.so.5. The extracted-artifact verifier removes the identical unsafe loader/graphics/shell set before direct helper smoke while preserving feature/debug selectors such as LIBGL_ALWAYS_SOFTWARE. Snap fixes the wrapper PATH, removes exported BASH_FUNC_* functions, and launches probe/playback through the regular executable $SNAP/graphics/bin/graphics-core22-provider-wrapper; a missing or disconnected provider returns snap-graphics-provider-unavailable before helper spawn. The packaging-only --embedded-mpv-runtime-probe app switch runs the complete cached manifest/hash/helper gate before BrowserWindow startup and exits with one availability JSON line. A nonzero helper exit keeps top-level reason helper-probe-failed; helperReason is present only for an exact protocol-v1 line carrying a fixed allowlisted reason, and its optional helperDetail must be 1–1024 printable ASCII characters. Invalid detail suppresses both helper fields. Every probe uses an explicit 16 MiB aggregate captured-output ceiling independent of tracing. With IPTVNATOR_TRACE_PLAYER=1, a non-empty helper stderr capture is emitted separately as one JSON-escaped stderr line whose stderr field is limited to 16,384 characters and whose truncated field is always explicit; trace-write failure cannot change the capability result. Installed-Snap CI enables Mesa EGL/GL diagnostics through this bounded channel. Any loader failure remains a stable native-view fallback, never a flag-enabled success.
• In the exact packaged Flatpak /app context, reconstruct only Freedesktop Platform 24.08's immutable __EGL_EXTERNAL_PLATFORM_CONFIG_DIRS; its GL extension loader path comes from the sandbox cache. Flatpak CI must invoke the application-level --embedded-mpv-runtime-probe, not a direct helper probe that bypasses capability detection.
• The packaged x64 Playwright smoke runs its fixture-contract target first and passes Chromium --ignore-gpu-blocklist so CI llvmpipe can expose WebGL2. This launch-only flag does not bypass the manifest, hash, loader, or helper capability gate; --no-sandbox remains root-only.
• Bundled Linux releases must publish the exact source archives/git records, checksums, licenses, flags, patches, build scripts, and the pinned hwdata pnp.ids input. Each bundled package carries embedded-mpv-notices.json, THIRD_PARTY_NOTICES.txt, and the exact licenses/** files. CI may cache immutable source inputs, but regenerates notices and a VCS-metadata-free linux-frame-copy-runtime-sources.tar.xz for the current checkout on every run while retaining the exact pinned six recursive libplacebo submodule records. Each record is canonical full-commit safe/path; clone-depth dependent git describe annotations are discarded and never form part of the provenance identity. Its source index carries the globally sorted libplacebo directory/file/symlink inventory; file hashes, sizes, executable bits, link targets, aggregates, and canonical tree digest must match the trusted pinned checkout. The archive has an exact member/type layout and its metadata/archive-sha256.txt records must match the actual source archives. Concatenated tar/xz streams are inspected past every end marker. The final archive's SHA-256 and repository revision are copied into every bundled x64 package manifest; system and marker-only packages carry no source-archive binding. Automated Snap Store publication is allowed only after a public v* GitHub release contains both the Snap assets and exactly one matching source archive. Before any upload, the workflow hashes and inspects that archive, verifies its exact member/type set and size bounds, clean tag revision, pinned sources including the six recursive submodule records and exact libplacebo tree digest, legal files, and exact released tooling, then performs bounded extraction and static package validation for every Snap. That public-release boundary independently revalidates the exact strict meta/snap.yaml graphics/shared-memory contract and enumerates resources/app.asar, rejecting any archived electron-backend/native/** payload before publication. Its bounded ASAR header reader uses only Node built-ins and released local tooling, so the clean tag checkout does not require node_modules. Exactly one x64 Snap must have matching sourceArchive and sourceRuntime; any non-x64 Snap must remain marker-only. Checkout and the artifact-transfer actions are pinned to full commits; checkout does not persist credentials, and repository credentials are limited to download steps. A secretless verification job copies assets through no-follow descriptors, checks pre/post hashes, writes an exact receipt, repeats the complete source/package verification on a root-owned read-only snapshot, and transfers only that data through the pinned artifact service while its receipt digest travels separately through a job output. The dependent publish job runs on a bounded ubuntu-latest runner with no checkout or release-tag code, verifies that digest plus the exact receipt, asset hashes, and file-only layout, root-seals the data again, and installs Snapcraft directly. Store credentials exist only in its final fixed shell step, which resolves no PATH command, executes no released code, and exposes the credential only to each exact /snap/bin/snapcraft upload --release=edge process. Candidate/stable promotion is manual after installed-Snap frame-copy and missing-runtime fallback smoke; GitHub Actions never promotes automatically.

General Guidelines for working with Nx

• For navigating/exploring the workspace, invoke the nx-workspace skill first when it is available - it has patterns for querying projects, targets, and dependencies. If it is unavailable, use pnpm nx show projects, pnpm nx graph, and project project.json files directly.
• When running tasks (for example build, lint, test, e2e, etc.), always prefer running the task through nx (i.e. nx run, nx run-many, nx affected) instead of using the underlying tooling directly
• Prefix nx commands with the workspace's package manager (e.g., pnpm nx build, npm exec nx test) - avoids using globally installed CLI
• You have access to the Nx MCP server and its tools, use them to help the user
• For Nx plugin best practices, check node_modules/@nx/<plugin>/PLUGIN.md. Not all plugins have this file - proceed without it if unavailable.
• NEVER guess CLI flags - always check nx_docs or --help first when unsure

Scaffolding & Generators

• For scaffolding tasks (creating apps, libs, project structure, setup), ALWAYS invoke the nx-generate skill FIRST before exploring or calling MCP tools

When to use nx_docs

• USE for: advanced config options, unfamiliar flags, migration guides, plugin configuration, edge cases
• DON'T USE for: basic generator syntax (nx g @nx/react:app), standard commands, things you already know
• The nx-generate skill handles generator discovery internally - don't call nx_docs just to look up generator syntax
