# E2E coverage for today's (2026-05-18..19) merged PRs that landed with
# unit tests only. Each section asserts the FIX-SPECIFIC behavior through
# the REAL HTTP / DB / activity path, no mocks for the unit under fix.
#
# Covered PRs:
#   - mc#1525 + mc#1542 — GIT_ASKPASS + GIT_HTTP_USERNAME/PASSWORD env-inject:
#     a fresh workspace receives both halves so `git ls-remote https://…`
#     against the persona token succeeds (rc=0) inside the container.
#   - mc#1535 + mc#1536 — per-workspace MCP server-name slugs: two
#     workspaces created back-to-back must surface DIFFERENT
#     {{MCP_SERVER_NAME}} values in their external-connection snippets
#     (regression for "claude mcp add molecule -s user" overwrite class).
#   - mc#1539 — self-delegation echo gap closure on the inbox layer:
#     a workspace that self-delegates must NOT see its own timeout
#     surface in the inbox as a `peer_agent` row sourced from itself.
#
# Requires: platform running on $BASE (default http://localhost:8080)
# with at least one online agent available for the self-delegation leg.
