Recovery from the merge-gate rebase-conflict bounce. The feature branch was
rebased onto origin/main (which had merged ORCH-123). The single conflicting
hunk — docs/architecture/README.md — was resolved during the rebase: kept
ORCH-123's host-side staging-runner line AND the ORCH-116 test-runner bullet.
This follow-up commit reconciles the remainder:
- Renumber the global sweeping ADR adr-0049 -> adr-0050. ORCH-123 took adr-0049
(adr-0049-host-side-docker-execution-boundary.md) on main while ORCH-116 was
in flight, so ORCH-116 yields to the merged task and moves to the next free
number. Mechanical cross-reference reconciliation only (git mv + title + every
test-runner reference across README/internals/CLAUDE/CHANGELOG/config.py +
06-adr/ADR-001 + 12-review). Main's adr-0049 host-side references are left
byte-for-byte untouched. No design/verdict content was altered.
- Restore the ORCH-116 CHANGELOG entry that the CHANGELOG auto-merge silently
dropped (both ORCH-123 and ORCH-116 inserted at the same [Unreleased] anchor;
git kept only ORCH-123).
- Add the missing ORCH_TEST_RUNNER_* keys to .env.example (parity with the
ORCH_STAGING_RUNNER_* block; ORCH-101 canon of start keys).
