Resilience + scale pass on top of the v1 core. Stream health prober: - New SSRF-validated /probe endpoint (HEAD -> ranged-GET fallback, 6s timeout, 5-min TTL cache, concurrency-capped, no-store) + orb_probe_total metrics - Front-end health.js: lazy bounded-concurrency probing (current + sampled channels, not the whole catalog), LIVE/DEGRADED/DEAD scoring, guide skull glyph, instant no-signal on zap to a known-dead channel Oracle's Memory (memory.js): - Session resurrection (last channel, volume, mute, theater/dim/ambient) - Exponential-decay per-channel uptime history; pinning; dead-channel auto-skip Off-thread XMLTV: - lib/xmltv-parse.js (pure, hand-rolled scanner, no DOMParser/regex backtracking) run in epg-worker.js module worker; wired into the iptv-org provider - Unit-tested in node: entity decode, TZ offsets, 20k programmes off-thread Service worker / PWA: - manifest.webmanifest + orb icons; sw.js (cache-first shell + hls.js, stale-while-revalidate for JSON-over-relay, never caches streams) - CSP gains worker-src + manifest-src; relay sends no-store on /relay + /probe so the SW is the sole metadata freshness authority; webmanifest MIME fix Docs: README de-emojified (title only) and reframed as a peer parallel build. Verified: SSRF probes blocked, legit probe + cache, new headers present, PWA assets served, parser tests 8/8, JS syntax clean, zero Rust warnings.
