The long band is picked when a stall repeats and either the connection was closed by Cloudflare mitigation or lease mode is off, and lease mode (`tengu_slate_lantern_ember`) defaults to off, so a stock build takes the long band.\n\n**Details**\n\n- New timing constants: `longStallMinMs: 120000`, `longStallMaxMs: 240000`, `stallOutJitterMs: 900000`.\n- Give-up deadline is now per run: `maxStallMs` plus a random amount up to the jitter.\n- A counter event fires once per stall run carrying a startup flag and, when known, `http_status`.\n- The numbers are compiled in and copied into state; nothing in this build overrides them remotely.\n\n**Evidence**\n\n`stallOutJitterMs`, `stall_run_started`\n\n- Flag `tengu_slate_lantern_ember`: Off by default, switched on for this account (read for one account on one subscription tier against v2.1.250; this account: on, anonymous baseline: on, compiled default: off)\n- Area: Artifacts\n- Names: `tengu_slate_lantern_ember`\n- Tier: You'll notice\n- Useful: 3\/5\n- Signal: 4\/5"}
