plan(D-AW): base single-sourced + OGAR per-app mint — the shrinkable two-place awareness model#731
Conversation
…e two-place model Operator directives (2026-07-18) fold into the M20 assembly plan: - Base layout has ONE root (lance-graph-contract), consumed by the OGAR-aligned cluster (lance-graph-ogar + OGAR + ogar-vocab). Awareness facets are OGAR-minted ClassView READINGS over one reserved facet region, NOT 19 named base ValueTenant variants — supersedes the auditor's bake-19 path. Activation overridable in 2 places (base region + OGAR mint); shrink later = re-mint (drop redundant readings), no base edit, no ENVELOPE_LAYOUT_VERSION bump. - Reuses the mechanism #729 P4 SHIPPED the same day: MailboxSoaView::style_rails_at (6x(8:8) ClassView-selected reading) + the "one register, two readings, per-class-not-per-lane" doctrine (3248bd9). Awareness facets = additional style_rails_at-shaped readings, one rung wider; style_lane_at (226-atom FROZEN palette256) is the frozen sibling. - Single-import prerequisite = close ENTROPY M21 (woa-rs/q2 NodeGuid hand-copies). symbiont is deprecated (surrealdb -> OGAR); its bridge.rs NODE_ROW_STRIDE copy retires with symbiont, not a fix target (drops the W2c SurrealDB arm from the live path). - Auditor LAYOUT-GATED verdict re-scoped: the delta is now reserve ONE facet region + the reading contract, re-audit needed before any canonical_node.rs edit. Rebased onto origin/main (picks up #729 P4 triangle bricks + the merged D-AW-1 via #730). Doc-only.

How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

There was a problem hiding this comment.
This plan makes the per-app awareness projection a ClassView value_schema, but the current contract's ClassView::value_schema returns only the ValueSchema enum preset (Bootstrap/Cognitive/Compressed/Full), and ReadMode.value_schema only selects which fixed ValueTenant set materializes (crates/lance-graph-contract/src/class_view.rs:1133, crates/lance-graph-contract/src/canonical_node.rs:1198). As written, an OGAR mint cannot encode different SpoFacet/PearlRung/sibling readings without either adding a new projection axis/API or hardcoding additional presets, so following this plan would leave the intended per-app facet readings unrepresentable.

What
Follow-up to the merged D-AW-1 plan (#730), folding two operator directives (2026-07-18) into the M20 awareness-assembly design. Docs-only (the plan file); no code carve yet.
The correction
The auditor's LAYOUT-GATED verdict audited "add 19 named
ValueTenantvariants to the base +Fullmask." Operator ruling supersedes that: 19 named base variants makes every M20 shrink a base-layout edit + version bump + blast radius across every consumer — the opposite of shrinkable. The correct, shrinkable shape:lance-graph-contract(one root), consumed bylance-graph-ogar+OGAR+ogar-vocabFacetCascadeshape. Content-blind.ENVELOPE_LAYOUT_VERSIONogar-vocabper-app mintvalue_schemaprojects the awareness readings onto the regionAwareness facets (A1–A7 + siblings) are OGAR-minted ClassView READINGS over one reserved region, not base enum variants → activation overridable in 2 places, cheaply tested, versioned, shrunken later (the M20 endgame: after jc measures redundancy, shrink by re-mint).
