- ADR-013: V0-framed push machine grounded in real git 2.43.0 captures
(file://, git://, smart-http mock, raw stdio into real receive-pack):
V0-shaped ref advertisement (caps on first ref line, capabilities^{}
sentinel only for empty repos), served capability set, shallow requests
rejected for v1, thin packs accepted with server-odb bases (no
capability involved; push.thin default), ingestion bound to
Bundle::write_to_directory_eagerly + gix-fsck + one gix-ref transaction
per push (.keep-guarded), unpack-first CAS timing with observed
upstream order, band-1 pkt-line-framed status report, http framing
(probe/Content-Length/chunked), v1 update policy (CAS only; deletes
and force-push allowed)
- docs/research/push-captures.md: the normative push wire record
- transport.md/backend.md/doors.md: receive-pack sections rewritten to
the decided shapes; backend.md ingestion composition bound; stale
OQ-04 references resolved
- ADR-003 amended: V2-only governs fetch; push is V0-framed by upstream
design (fixes the V2-only contradiction found in review)
- ADR-009 amended: haves default reconciled with the client's stateless
ceiling (16384); blocking-pipeline budget covers generation+ingestion
- OQ-04 resolved; tracker task closed; CAS-fail-fast optimization
tracked (tasks/architecture/oq-13-cas-failfast.md)
- research index: poc findings + capture docs listed
Verification: cargo test / clippy -D warnings / fmt --check / doc pass

Description
Tracker for OQ-04 (deferred(unclear)): receive-pack (push) design
validation. Resolved early (2026-09-25, ADR-013) — the investigation
was run in-session rather than waiting for scheduling: real git push
captures (git 2.43.0 over file://, git://, smart-http, plus raw stdio
requests into real git receive-pack) resolved the full push state
machine. OQ-04 is resolved by
docs/architecture/decisions/013-receive-pack-state-machine.md; captures
in docs/research/push-captures.md.
Work
None by default. On trigger: set OQ-04 to open in
docs/architecture/open-questions.md and spawn the focused session that
works through the push state machine. (Triggered and completed in the
2026-09-25 session.)
Verification
- OQ-04 status matches this task's state in
docs/architecture/open-questions.md(resolved).
Out of scope
- Actually implementing receive-pack (phase 3 implementation work).
Summary
Resolved early via ADR-013: the walkthrough ran in-session; all seven unknowns (advertisement set, shallow policy, thin-pack acceptance, ingestion composition, CAS timing, status report, version/framing surface) have capture-grounded decisions.
