Lance 7.0.0 shipped stable 2026-05-28 and still pins datafusion = "^53"
/ arrow = "^58" (verified against the published 7.0.0 dependency
manifest), so the pending 6.0.1 -> 7.0.0 bump is not a DataFusion bump:
the "Passive wins" table is unchanged.
- Current-pin stanza: note 7.0.0 is available upstream and holds DF ^53.
- Tier 2: the delete-Expr item's upstream gate (execute_uncommitted,
lance#6658) is now satisfied (in 7.0.0 stable); reframe the trigger as
our own 6->7 bump rather than waiting on a Lance release.
- Upstream cadence: correct the pre-release speculation — 7.0.0 stayed on
DF 53; a DF 54/55 jump is deferred to a later Lance.
- Drop the brittle exec/query.rs:771-796 line range (drifted; hydrate_nodes
is at 863 on main) in favor of the stable function name.

Captures the post-PR #111 (Lance 4→6) + PR #113 (structured Expr
pushdown) DataFusion state in one place, so future maintainers don't
have to re-derive what's done, what's free, and what's still on the
table from chat history.
Structure:
- Direct touchpoints (only 2 — narrow surface)
- Shipped: PR-by-PR delta of what's landed
- Passive wins active on DF 53 (PR-linked, with where-it-bites-us
notes)
- Still on the table, ranked by tier:
- T1: structural, unblocked today (hydrate_nodes Expr pushdown)
- T2: gated on Lance v7 (delete Expr via MR-A / issue #112)
- T3: future-shape unlocks (extension planner, expression
placement, etc.)
- T4: won't reach us without major changes (custom ExecutionPlan
territory)
- Upstream cadence note (Lance dictates the DF version)
- Maintenance section
Linked from docs/dev/index.md so the check-agents-md CI guard
passes.
