feat: rename FastCrest Reflex OSS to Tether (v0.12.0)#209
Merged
Conversation
Salvages the rebrand work the prior agent did before its watchdog timeout. - pyproject.toml renamed package to "tether"; entry point: tether = "tether.cli:app" - src/tether/ now exists alongside src/reflex/ (shim) - src/reflex/_redirect.py emits DeprecationWarning + forwards CLI to tether - ~20 doc files + workflows + Dockerfiles updated for new name - README, docs/, CONTRIBUTING all reference Tether (formerly Reflex) What remains (follow-up commit in this PR): - Final wiring of src/tether/__init__.py env-mirror - Test pass: pytest tests/ -x - Backwards-compat test (from reflex import X still works) - Repo rename via gh api (post-merge action by user) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
…her salvaged) - src/reflex/__init__.py: full DeprecationWarning + re-export shim - tests/test_backwards_compat.py: 3 tests proving the shim works - tests/test_observability_prometheus.py: preserve reflex_* wire-level metric names Salvaged from finisher agent that stalled on silent pytest run.

The salvaged rename commit changed the test payload from "reflex-vla-sha256-test" to "tether-vla-sha256-test" but left the expected hash digest pointing at the old payload, so test_sha256_large_file failed with a hash mismatch (7e889344... vs the stale be4d788a...). Recomputed the digest for the new payload and updated the assertion. Per CLAUDE.md: no band-aids. The hash IS the contract; verification.py's _sha256 is correct, the test fixture was just lagging behind the rename. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Summary
Renames the FastCrest OSS deploy CLI from
reflex-vla/reflexto Tether. Per the 2026-06-03 brand decision: one brand (FastCrest) with one OSS product name (Tether) that captures the hybrid edge-to-cloud thesis.What is in this PR
