Address the Codex GPT-5.5 review of the standalone fake C++ gRPC Shard
worker. Four root protocol defects fixed:
- Fail closed before SessionOpen: a per-session `opened` flag gates
chunk/decode so no activation bypasses lifecycle, cancellation, epoch
or flow-control state (terminal ERROR_CODE_INTERNAL), even when an
out-of-band Cancel created placeholder state.
- Strict flow-control negotiation: NegotiateFlow takes the strictest of
peer-vs-worker bounds (mirrors codec.negotiate_flow_control) and the
negotiated per-session max_chunk_bytes is enforced on every bundle
instead of trusting the peer proposal.
- In-stream ReleaseSignal now erases session state immediately.
- SessionOpen rejects incompatible schema, fingerprint, and shard-range
identity and reports the worker's own served fingerprint rather than
echoing the caller.
Adds 9 regression tests (worker suite 18 -> 27). Real gates on the
rebuilt pinned-gRPC binary: cmake build exit 0; ctest 2/2; worker
pytest 27 passed; harness+protocol 63 passed; compileall 0; diff --check
clean; ldd/nm show 0 llama/ggml linkage. DGR-033 passes -> true.

Derive the recipe's runtime_version axis from the DGR-027 lock manifest
(exact upstream commit + ordered patch-stack byte digest) in new
meshnet_node.runtime_pin, failing closed on any lock/series/SHA256SUMS/
patch disagreement, and enforce pin discipline on runtime_version in both
the node and tracker identity implementations.
Also repair pre-existing backlog consistency: add missing DGR-022/DGR-027
completionNotes, regenerate the DGR-022/025/027 issue projections, and
relocate three pre-DGR legacy GLM issue files to issues/legacy/. Mark
DGR-025 passes=true with evidence at evidence/DGR-025/README.md.
