board: PR #81 arc entry + LATEST_STATE - #82
Conversation
Discharges the merged-PR obligation for #81 at merge time, not as a backfill: the Panama x Valhalla framing, the RangeOutOfBounds fix and its falsifier, the 409/183 gate results, the flattening cliff reproducing on JDK 28 with RowRange and Row on the wrong side, the two allocation measurements that got worse, the lab re-scope and its removed confound, and the JMH numbers still owed.

The claim that no CI job compiles the native crate contradicts .github/workflows/lint.yml: both the clippy and rust-test jobs check out the lance-graph sibling and run cargo clippy --all-targets or cargo test --all-targets from native/lgj-abi. The actual coverage gap is that an upstream-only change does not trigger this repository's workflow, so recording the broader claim obscures the real cross-repository CI hazard.

Verified against .github/workflows/lint.yml; the finding is correct. Fixed in 229ff39.
The clippy and rust-test jobs check out sibling AdaWorldAPI/lance-graph (plus ndarray and OGAR) and run cargo clippy --all-targets -- -D warnings and cargo test from native/lgj-abi, so the native crate is compiled against the real sibling on every push and PR to this repo.
The gap is the trigger: on: {pull_request, push} fires for events in this repository only, so an upstream-only merge in lance-graph — which is what added ExecError::RangeOutOfBounds — cannot start the workflow, and the break stays invisible until the next push here.
Corrected in place in the #81 arc entry (unmerged), and by prepend as E-THE-CI-GAP-WAS-THE-TRIGGER-NOT-THE-COVERAGE-1 for the copy merged via #81, the board being append-only.

that the absence of row hydration applies to production, changing “no row
hydration introduced” to “no production row hydration introduced” while

Codex P2 on #82, verified against .github/workflows/lint.yml: the claim that no CI job here compiles the native crate is false -- the clippy and rust-test jobs check out the lance-graph sibling and run cargo clippy --all-targets and cargo test from native/lgj-abi on every push and PR to this repo. The real gap is the trigger: on {pull_request, push} fires for this repository only, so an upstream-only merge in lance-graph cannot start the workflow and the break stays invisible until someone pushes here. Corrected in place in the unmerged #81 arc entry, and by prepend for the merged epiphany.

Framing torque flagged in review on #82: the repo kept saying 'the Valhalla lab' after #81 made production the Valhalla arm, which reifies the superseded topology (Panama real, Valhalla experimental annex) the implementation had just removed. - docs/panama.md carried an objectively stale paragraph: the lab compiled with -source 27 --enable-preview and was 'never on the classpath the production tests run against', with physical separation as a structural guarantee against preview poisoning. All three are false now -- both arms are JDK 28, both load the production API, and that API is itself preview-marked. - README's stack diagram drew 'stable-JDK implementation / Valhalla laboratory' as layers; replaced with JDK 28 Panama + JEP 401 production and representation probes. - docs/valhalla-lab.md gains a legacy-name banner; the directory keeps its name for path compatibility. - The #82 arc bullet and LATEST_STATE now name the experiment as object-model and layout consequence, not Valhalla. Historical board entries are left as history. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01HScwwezRdMxFfTs3WLG19d

Board entries now name the experiment as object-model and layout consequence — Valhalla is production infrastructure; what remains under test is JVM representation economics. Generated by Claude Code |
CodeRabbit on #82: the entry claimed 'no row hydration introduced' three bullets after reporting a hydrate 65,536 Row measurement. That measurement is a lab probe of what hydration would cost, not a production path, so the unqualified claim contradicted the entry's own numbers.

Rewrites two passages as guidance for the next session: the CI note now says do not add a job (one exists) and names upstream-change notification as the open gap; the harness note states the CWD requirement and how to run the flip correctly. Technical content unchanged. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01HScwwezRdMxFfTs3WLG19d

Board hygiene only. Discharges #81's merged-PR obligation — written at merge, not backfilled as #79's was.
The arc entry banks what a future session would otherwise have to re-measure:
RangeOutOfBoundscross-repo break and its disable-verified falsifier, with the standing hazard named — an exhaustive match across a repo boundary turns an upstream additive change into a downstream build failure, and no CI job here compiles the native crate;RowRangeandRowon the wrong side — sovalue semantics ≠ flatteningis recorded against a real production type;Rowhydration), kept rather than dropped;bench/libabsent here), sobench/RESULTS.mdstays JDK 26 historical.Per this repo's board rules the entry lands in its own commit after the merge sha exists; no code, no ABI, no doc contract changes.
