• 🔴 (13:15) User stated telemetry must never break the embedding path.
• 🔴 (13:15) User stated a host logger or sink must never interrupt embedding-worker stream consumption.
• 🔴 (13:15) User stated CommonJS uses __filename, which is always defined there; ESM uses import.meta.url.
• 🔴 (13:15) User stated the last self-heal re-probe timestamp uses epoch milliseconds, with 0 meaning “never,” and is primed on the first tick.
• 🟡 (13:15) The embedding runtime defines EMBED_REPROBE_INTERVAL_MS = 5 * 60_000, a 5-minute self-heal re-probe interval.
• 🟡 (13:15) The worker fallback cache path is path.join(os.homedir(), ".cache", "lore", "worker.cjs").
• 🟡 (13:15) The embedding worker drains both output streams, including drainEmbeddingWorkerStream(worker.stderr, "stderr"); logger/sink failures are isolated so stream consumption continues.
• 🟡 (13:15) The embedding runtime reports upward cap recovery with the message embedding cap re-probed up: ≤${prev} → ≤${next} tokens (free memory recovered).
• 🟡 (13:15) Embedding failure handling includes an "oom-backoff" failure kind and bounded resubmission of in-flight requests after the live token cap shrinks.
• 🟡 (13:15) A synchronous worker respawn failure, such as new Worker(...) throwing, is handled as a rejection path rather than being allowed to cause silent data loss.
