From 7abd17393df62c8020e4922be8b226bda6b9bde0 Mon Sep 17 00:00:00 2001 From: ZeR020 <88128532+ZeR020@users.noreply.github.com> Date: Mon, 17 Aug 2026 14:54:50 +0000 Subject: [PATCH] feat(cli): add pi-hook-ingest/inject with shared spool HTTP-first pi ingest on /api/pi-hooks, direct path via buildRawEventEnvelopeFromPiEvent + ingestRawEvents. Drain the shared spool before a boundary flush.
