keryx-miner-supr 0.14.4

Inference fixes for the H14 private-inference era, and an AMD dashboard fix. Recommended for every rig that serves inference, especially cards on the larger tiers (Qwen3.8-27B, Kimi-Linear-48B), which can now answer long private requests.

Fixed

• Private prompts larger than 4 KiB were refused. Before H14 an inference request was limited to 4 KiB and so was the miner (prompt exceeds 4096 bytes). Since the H14 gate, private requests can carry up to 64 KiB, and a compressed prompt can expand to more. Every valid larger request was refused and counted as a miss. The miner now accepts prompts up to 1 MiB, and each card decides by its model's context size whether the prompt fits. A prompt too large for a card's context is refused for that request only: the card keeps its model, stays serveable and keeps mining.
• A large inference request dropped the pool connection. The miner read pool messages with a 64 KiB line limit. A request carrying a prompt above about 48 KB exceeded it, and the miner disconnected and reconnected 30 s later, losing the request and any shares in flight. The limit is now 2 MiB, and a pool message that is still too large is skipped without disconnecting.
• AMD: two cards shown as INF. On AMD rigs where one card is reserved for inference, the dashboard also marked a second card INF whenever a request was served, although that card was mining (it numbered the serving card differently from the dashboard). Now only the reserved card shows INF; during a request the other cards show as paused, then mining again.

Tested

On an RTX 5090 serving Qwen3.8-27B (64k-token context) after the H14 gate, against a test pool with the node's share verifier:

Every answer recalled a code word placed at the very start of the prompt, so the whole context was read. 982 shares, 0 rejected. Also verified on the live pool.

Which download

No consensus, PoM or model changes; mining speed is the same as 0.14.2. H14 gate handling is unchanged. (0.14.3 was not released; its fixes are included here.)
