Cap the forge's database pool at 40: the store's 100 connections are shared (issue 1966, recovery) #632

Recovery fix (mesh instruction recovery-fixes-merge-and-tell), on the operator's yes (2026-11-08 ~02:00, "cap the forge pool"); merged by lead-47@shanks, the operator told at the terminal.

Cause. The gitea module set no database pool limit (gitea 1.27.3 default MAX_OPEN_CONNS 0, unlimited). The store on novox has max_connections 100 for every module there. Live 2026-11-08 01:35-02:07: the forge held 40-84 connections, the store refused everyone else in bursts ('remaining connection slots are reserved'): builds, a push to hq, the knowledge base and the store's own reader failed.

Fix. files/server.env: GITEA__database__MAX_OPEN_CONNS=40, MAX_IDLE_CONNS=10, CONN_MAX_LIFETIME=5m. Over 40 the forge's requests wait for a connection (database/sql), they do not fail. Checked in the 1.27.3 source: SSH gitea serv and the git hooks reach the database through the main server's private API, so this pool carries them; admin-bootstrap reads the same env file. The delivery recreates only the forge container (changed env-file digest).

Quick vs thorough. This is the quick, one-module guard for the store. The cause of the demand (Go builds' git fan-out and the callers of the forge's API) is a note on issue 1966 for a thorough fix.

Watch after delivery. pg_stat_activity: the forge at 40 or fewer, no refusals; the forge's health and latency (a transaction holding one connection while asking a second could stall under a cap).

Tests. modules/gitea/test/pool-cap.test.ts (fails without the change).

Undo. Revert this merge commit.
