- 2026-07-31 04:56:22 — part of check-in [562cf5be74] on branch sub-manifest — merge trunk: shun, the release-assert guard, and the split test lanes
  Trunk since d186a44e brought the repository shun table and its whole- branch verification fixes, the release-assert guard, the `test`/`gate` lane split, the structurally bounded logstore priority window, and the vendored crc32. Eight files conflicted. The decisions worth naming:
  Lanes. `git-import-e2e` was a compile-only proof hanging off `test`; that is exactly the cost trunk moved to `gate`, so it moves with `e2e` and `smoke`. `import-git-bench` stays on `test` because it registers a real unit-test run rather than a compile proof. `declared_steps` is the union plus `gate`.
  Sync ingest. Both sides rewrote it: trunk added the §7.7 receive-side shun admission, this branch added §7.1 phantom minting for a pushed tree's missing sub-manifests. They compose in one direction — admission is asked first, so a card §7.7 refuses is never stored and mints no phantoms either. The S references of an artifact this repository declines to hold are not names it should then go begging for.
  Client construction. Trunk factored the three verbs' `Client` literal into `syncClient` and threaded `RepoAdmission`; this branch had widened `project_code` into `RepoSyncIdentity`. The helper now carries both, which is what trunk's own comment asked for: three copies of that literal is how a repository filter comes to be wired into two verbs and not the third.
  Per-round server refresh. Trunk made the snapshot mandatory — `error.ServerStorage` rather than serving with no shun table — where this branch read its four sub-manifest fields through fail-open defaults. Trunk's reading wins for all six fields: serving a stale default is the failure, not the fallback.
  Two guards trunk owns caught real defects in this branch's code, which is the whole point of them:
  The total switch in `shunConsequence` refused to compile against the `submanifest` artifact type, exactly as its comment promised. It has an arm now.
  The release-assert guard found nine asserts on untrusted input across six functions. Two were reachable faults, not style: `lookupTree` asserted §4.4 on a sub-manifest a peer supplies, so a malformed node panicked a ReleaseSafe reader and was walked anyway under `--release=fast`. It returns `SubUnresolvable` now, which §5.2 already defines as "absent, or is not a SUBMANIFEST". The empty-S-run assert became an early `null`. The two sub-manifest writers refuse an empty group through a new `SubmanifestWriteError` rather than asserting; the builder's internal path keeps its allocation-only surface through `serializeLeafCore`, since the partitioner is what establishes non- emptiness there. The rest were tautologies or restatements of invariants the card parser already enforces, and now say so in a comment instead of carrying a panic.
  Verified on the merged tree: `gate`, `e2e`, `dst` (6 seeds x 1000 steps), `smoke` (S1-S10, including trunk's new shun interop), and `git- import-e2e` all green, `zig fmt --check` clean. Beyond the suite, the importer was run for real: the empty-email repro imports and its check- in carries `U mohye77`, and marktext imports end to end with the analyzed pin at k=5.
