- ADR-014: the multi-round ack loop, grounded in duplex git 2.43.0
captures cross-checked against fetch-pack.c: no-done rounds get
acknowledgments (ACK <oid> per recognized have, NAK when none, flush;
never ready so FLUSH is always the terminator), the done round
generates closure(wants) - closure(haves) with no cross-round server
state (clients re-send wants + commons every round), wait-for-done
stays (no capability change), want-less rounds answered empty, the
ack check is a new GitPackGen::common_haves seam (honest boundary at
the trait), budgets unchanged kinds
- docs/research/negotiation-captures.md: the normative negotiation
record (grammar, client behavior, malformed-section failure modes)
- transport.md: fetch section rewritten to the decided loop; references
updated
- OQ-02 resolved
Verification: cargo test / clippy -D warnings / fmt --check / doc pass
