+### Session 24 — 2026-05-22 — Gitea PR metadata wrapper hardening
+
+- Fixed `packages/mosaic/framework/tools/git/pr-metadata.sh` Gitea path to fail closed on non-2xx API responses instead of normalizing API error JSON into null/empty PR metadata.
+- Added token fallback behavior: try explicit `GITEA_TOKEN`, Mosaic credential-loader token, then matching `~/.git-credentials` HTTPS token; this handles stale host-scoped credential-loader entries while preserving existing credential sources.
+- Confirmed real U-Connect Gitea PRs #1905 and #1908 now return `number`, `headRefName`, `baseRefName`, `state`, `author`, `url`, and `mergeable` correctly, restoring `pr-merge.sh` base branch detection.

-# t_a292e96f — Gitea PR metadata wrapper fix
-
-## Objective
-
-Repair Mosaic git wrappers so Gitea PR metadata and merge preflight work for U-Connect PRs on `git.uscllc.com` without selecting the unrelated `git.mosaicstack.dev` tea login.
-
-## Findings
-
-- Reproduced the failure from `/src/uconnect-worktrees/t_39ce717c-authentik-smoke-gate` with the current `pr-metadata.sh`:
-  - PR #1905 returned JSON with `number=null`, `baseRefName=""`, `headRefName=""`.
-  - PR #1908 returned JSON with `number=null`, `baseRefName=""`, `headRefName=""`.
-- Root cause: the wrapper treated HTTP/API error payloads as PR payloads and normalized missing fields to empty strings.
-- The credential loader can return a non-working `git.uscllc.com` API token in this environment, while host-specific `~/.git-credentials` basic auth succeeds. The wrapper now falls back by host before normalization.
-- `tea login list` has only `git.mosaicstack.dev` configured here; `pr-merge.sh` previously forced `--login mosaicstack`, which is invalid for `git.uscllc.com` and caused `Login name mosaicstack does not exist`.
-
-## Changes
-
-- `packages/mosaic/framework/tools/git/detect-platform.sh`
-  - Added `get_gitea_basic_auth <host>` to retrieve host-specific HTTPS credentials from `~/.git-credentials` without printing secrets.
-- `packages/mosaic/framework/tools/git/pr-metadata.sh`
-  - Uses strict bash mode.
-  - Checks Gitea HTTP status and fails nonzero on API errors/non-JSON instead of emitting empty branch fields.
-  - Falls back from token auth to host-specific basic auth.
-  - Normalizes standard `head.ref`/`base.ref` and fallback branch fields.
-  - Requires non-empty `headRefName` and `baseRefName`.
-  - Preserves GitHub `gh pr view` behavior.
-- `packages/mosaic/framework/tools/git/pr-merge.sh`
-  - Reads metadata once for base-branch policy preflight.
-  - Selects a `tea` login only when its configured URL matches the repo host.
-  - Falls back to authenticated Gitea merge API when no matching `tea` login exists, avoiding the wrong `mosaicstack` login for USC repos.
-  - Keeps squash-only and main-only merge policy.
-- `packages/mosaic/framework/tools/git/test-pr-metadata-gitea.sh`
-  - Added fixture-based regression harness for standard Gitea fields, fallback branch fields, and API error payloads.
-
-## Documentation / changelog note
-
-This repository currently has no root `CHANGELOG.md`; the scratchpad and `docs/TASKS.md` carry the task-level change record for this wrapper fix.

-## Verification log
-
-- `bash -n packages/mosaic/framework/tools/git/{detect-platform.sh,pr-metadata.sh,pr-merge.sh,test-pr-metadata-gitea.sh}`: passed.
-- `shellcheck -x -P . -e SC1090 packages/mosaic/framework/tools/git/{detect-platform.sh,pr-metadata.sh,pr-merge.sh,test-pr-metadata-gitea.sh}`: passed.
-- `packages/mosaic/framework/tools/git/test-pr-metadata-gitea.sh`: passed; verifies standard Gitea fields, fallback branch fields, and nonzero API-error handling.
-- Live sanitized U-Connect metadata from `/src/uconnect-worktrees/t_39ce717c-authentik-smoke-gate` with `MOSAIC_CREDENTIALS_FILE=/src/jarvis-brain/credentials.json`:
-  - PR #1905: `number=1905`, `baseRefName=main`, `headRefName=edith/t_39ce717c-authentik-smoke-gate`, `state=open`, `host=git.uscllc.com`.
-  - PR #1908: `number=1908`, `baseRefName=main`, `headRefName=fix/t_23fa9e1d-portal-health-backend`, `state=open`, `host=git.uscllc.com`.
-- Merge preflight dry runs:
-  - PR #1905: `Dry run: would merge PR #1905 on git.uscllc.com with authenticated Gitea API fallback (base=main, method=squash).`
-  - PR #1908: `Dry run: would merge PR #1908 on git.uscllc.com with authenticated Gitea API fallback (base=main, method=squash).`
