From 9159b7e1b960afe86e6505e7b53ca88699034ffc Mon Sep 17 00:00:00 2001 From: Kev Date: Fri, 7 Aug 2026 04:24:21 -0400 Subject: [PATCH] Diagnose the push block: it was the wrong remote, not the firewall The GATE-0 theory is REJECTED for VYNDR, tested rather than assumed. Both remotes are ALREADY HTTPS -- there is no git@ SSH URL in this repo to be blocked -- and both hosts answer on 443: git.builtbykev.com HTTP 200 in 0.64s, github.com HTTP 200 in 0.17s, Gitea's git endpoint 200, GitHub's 401 (auth required, reachable). No connectivity failure of any kind. COLYRA's HTTPS-remote fix was right for COLYRA; VYNDR was already in the state that fix produces, so applying it would have minted a new token to solve a problem that did not exist -- and the pre-existing credential would have made the new token look like the cure. The real cause is in the error text, which named it exactly and was misread all session: "could not read Username for 'https://github.com'". Every attempt used `git push origin main`, and origin is GitHub (kev3109/betonblk) with no stored credential. The WORKING remote is `gitea` (git.builtbykev.com/builtbykev/vyndr.git), and a valid credential for it sat in ~/.git-credentials the entire time. The habit of typing `origin` is what kept twenty commits local. Nothing was blocked. FIX: git push gitea main. Pushed 6452926..ecf78b9, 21 commits, verified by git ls-remote matching local HEAD exactly. No firewall rule touched, no token created, no code or model change -- infra only. The bundle and patch series stay as belt-and-braces; they are no longer the only copy. docs/GIT-PUSH-DIAGNOSIS.md records it so no future session re-reaches for an infrastructure theory when the error message names a credential and a specific host.
