+# Handover — Landing Odoo + Redmine/OpenProject into OGAR (the ERP/planning Foundry shape)
+
+> **For:** the next session that lands Odoo (ERP) and Redmine/OpenProject (planning)
+> into OGAR.
+> **Date:** 2026-06-28.
+> **One line:** land each source in the *best native-yet-agnostic-yet-truthful*
+> shape — "Odoo"/"Redmine" are **labels**; the **ontology** is the canonical
+> ERP/planning form, and lance-graph is the Foundry it executes on.
+
+---
+
+## 0. The frame (do not re-derive)
+
+- **OGAR = the transpiler** (transpile-time): `ogar-from-*` parse a source AST →
+  the SPO/`ModelGraph` IR → classids, `ClassView`s, facets. It *produces shapes*.
+- **lance-graph = the Palantir-Foundry-shaped execution** (runtime): where those
+  shapes run / store / think. Consumers (medcare-rs, woa, smb, and the
+  ERP/planning apps) **execute on lance-graph**.
+- **Connecting tissue** (BBB-allowed in any consumer binary): `lance-graph-contract`
+  / `-ontology` / `-ogar` / `-callcenter`. The BBB bars only the **brain/engine**
+  crates (planner, cognitive engine).
+- **"Odoo" / "Redmine" are render labels** (the hi-u16 `AppPrefix`): Odoo=`0x0002`,
+  OpenProject=`0x0001`, Redmine=`0x0007`. The **lo-u16 canonical concept** is the
+  shared, agnostic identity. Same concept across apps ⇒ same lo-u16.
+
+## 1. Mission: native + agnostic + truthful
+
+- **Native:** faithful to the source's real model (Odoo's ORM fields/associations/
+  methods; Rails/AR `belongs_to`/`has_many`/`validates`/`acts_as_*`).
+- **Agnostic:** the landed shape is the **universal ERP/planning ontology**, not an
+  Odoo/Rails-specific struct. The label drops; the concept stays.
+- **Truthful (lossless):** nothing dropped. Each member lands in an ontology target
+  (below); the 16-byte facet is just the content-addressed index over it.
+- **Adjacent (drift-free):** ontologically-related concepts share a `part_of:is_a`
+  prefix; identity is by **reference** (one ClassView / one adapter, never copies);
+  the canonical codebook is single-source ("pull, never re-mint").
+
+## 2. The import contract (per member — the truthful shape)
+
+| source member | lands as | drift-proofing |
+|---|---|---|
+| `has_field` | a `ClassView` slot | reference |
+| `field_type` | the **type's** `ClassView` (recursive — types are classes) | reference, not copy |
+| `has_function` / Odoo method / AR callback | **ActionDef/KausalSpec ontology + a consumer wrapper over reusable OGAR adapters** (logic *extracted as ontology*, not reimplemented; for ERP this is the posting/validation behaviour) | shared adapter |
+| object type | the **shared codebook concept id** | canonical id |
+| ERP ontology glue (the ICD-analogue) | **FIBO** (finance grounding) + **DOLCE** (upper) + **SKR03/04** + l10n_de regulation IRIs (HGB/UStG/GoBD) | hierarchy / pivot |
+
+> Over-cap classes (`>= 256` members — Odoo has god-models) **branch** via the SoC
+> lint (`ruff_spo_address::soc` / `soc_branches`): data → ClassView(s) (paginate via
+> class hierarchy if `> 64` distinct types), behaviour → ActionDefs/adapters. Branch,
+> never widen.
+
+## 3. What already exists (grounded — build on it, don't reinvent)
+
+**odoo-rs** (private):
+- `od-ontology` — SPO triple corpus (`triple.rs`, ~13 predicates × 4 NARS bands);
+  `schema_to_classes` / `emit_via_ogar` (`ogar_bridge.rs`) lower Odoo → `ogar_vocab::Class`
+  (pulls classids via `OdooPort`, a pure static lookup — no bridge object/registry).
+- `od-posting` — **GoBD double-entry** posting host (gapless Belegnummer +
+  inalterability hash chain). This is the ERP *behaviour* arm.
+- `alignment::ODOO_SEED` (`pivot_uri` + DOLCE + `label_uri`, keyed by odoo_class) +
+  `data/ontologies/odoo/alignment/odoo-to-fibo.ttl` — the FIBO pivot already exists
+  on the Odoo side.
+
+**lance-graph** (`crates/lance-graph-ontology/src/odoo_blueprint/`):
+- ~404 curated + huge auto-extracted `OdooEntity` consts (`account` 685 KB, `stock`
+  383 KB, `l10n_de_chart` 864 KB / SKR03-04 **2466 rows** + **37 UStVA Kennzahlen**),
+  with fields, methods, state machines, German `regulation_iri` anchors.
+- `class_signature.rs` `StructuralSignature` / `shape_families` (FNV-1a histogram) —
+  **the route/form duplication clustering** (collapse identical-shape classes to one
+  shared ClassView).
+- `hydrators/{odoo,dolce_odoo,fibo}.rs` — Odoo hydrated as `OGIT::ODOO_V1` inheriting
+  `FIBOFND_V1` (FIBO Foundations).
+
+**OGAR** (the transpiler): `ogar-from-ruff` (Python/Odoo SPO frontend),
+`ogar-from-rails` (Rails/AR), `docs/{ODOO-TRANSCODING,ODOO-DIGEST-TO-OGIT,FOUNDRY-ODOO-MARS-LENS}.md`.
+
+**ruff** (the SPO frontends + mint):
+- `ruff_spo_triplet` — closed **60-predicate** vocab, the neutral `ModelGraph` IR,
+  `expand` ⇄ `reassemble` (NOTE: `reassemble` is **C++-projection-only today** — a
+  general reassembler is the first build item if you round-trip Python/Ruby).
+- `ruff_spo_address` — the 16-byte facet mint (`mint_with_classid(triples, classid_of)`),
+  `soc` + `soc_branches` (the SoC lint, ruff PR #33).
+- `ruff_ruby_spo` — Ruby/Rails frontend (lib-ruby-parser, `app/models`, **27
+  OpenProject AR predicates**); `NAMESPACE="openproject"`.
+- `ruff_python_dto_check` — Python harvester (→ JSON bundles; needs a `bundle →
+  ModelGraph` adapter to enter the same IR door).
+
+**lance-graph-contract** (the tissue):
+- `ogar_codebook.rs` — `CODEBOOK` (`0xDDCC` concept ids), `canonical_concept_id`,
+  `AppPrefix`, `render_classid`. **The cross-app join key.**
+- `class_view.rs` — `ClassView` (trait), `FieldMask`, `RenderRow`, `FieldRef`.
+- `facet.rs` + `facet_schema.rs` (lance-graph PR #619, **merged**) — the 16-byte
+  facet with classid-selected format (`6×2` cascade | `4×3` SPO | `2×48`).
+
+**Convergence proof (the agnostic identity, already wired):**
+`crates/lance-graph-ogar/tests/bridge_codebook_convergence.rs` — OpenProject
+`WorkPackage` & Redmine `Issue` → `project_work_item 0x0102`; `TimeEntry` /
+`Stundenzettel` / Odoo `account.analytic.line` → `billable_work_entry 0x0103`;
+Odoo `account.move`+`sale.order` → `commercial_document 0x0202`; `product.template`
+→ `product 0x0207`; `account.account` → `accounting_account 0x0208`.
+
+## 4. Redmine / OpenProject (the parallel landing — same methodology)
+
+- Frontend: `ogar-from-rails` / `ruff_ruby_spo` over `app/models` (the AR shape:
+  `belongs_to`/`has_many`/`validates`/`acts_as_list`/callbacks → the 27 AR predicates).
+- Identity: `WorkPackage`/`Issue` → `0x0102`; `TimeEntry` → `0x0103` (shared with Odoo
+  — that 0x0103 convergence is the planner↔ERP billable-hours pin).
+- Render: the **"17-year Redmine QueryColumn evolution"** lands as the `ClassView` +
+  `FieldMask` line-view (`ogar-render-askama::list_view`, `render_rows`) — the same
+  field-view primitive medcare's views use.
+
+## 5. The cross-domain map (the Foundry payoff — LATER, easy once truthful)
+
+ERP ↔ planning ↔ health align at the **ontology plane**, by:
+- **shared lo-u16 codebook concept** (the de-facto `owl:equivalentClass`, expressed
+  as a u16) — *the only mechanism wired today*;
+- **FIBO/DOLCE pivots** (Odoo already has `odoo-to-fibo.ttl`; author the symmetric
+  twins so domains inherit a common FIBO/DOLCE category via `ContextBundle.inherits_from`).
+
+## 6. Gaps the session must close (from the ontology-preservation verification)
+
+1. **Carry the codebook concept through the mint** — always stamp `facet_classid`
+   via the OGAR resolver; **never ship `classid=0`** (no join key, no ontology).
+2. **Promote groundings to typed data** — give each `CODEBOOK` row an optional
+   `{ogit_uri, dolce_category, fibo_equivalent_class}` (lift today's doc-comment
+   annotations), and thread it through the mint (don't drop it at the `_ =>` arm).
+3. **FK facet → registry** — put the concept u16 on `MappingRow` (O(1) facet →
+   `OntologyRegistry`; today it's indirect `ogit_uri` string-match).
+4. **Fix the OWL hydrator** — store subject→object edges so `rdfs:subClassOf` is
+   reconstructable (today it flattens s/p/o into one `iri_to_id`; TTL export hardcodes
+   a flat `rdfs:subClassOf ogit:Entity`).
+5. **Behaviour arm** — land Odoo methods / AR callbacks as `ActionDef` ontology +
+   reusable adapter, **not** reimplemented (od-posting's GoBD logic is the test case).
+6. **Land `odoo_blueprint` extracted entities as OGAR `Class`** via
+   `od-ontology::schema_to_classes` (the future `od-ontology-bridge` binary).
+
+## 7. Hard constraints
+
+- Lossless + truthful **now**; cross-domain tissue **later** (don't let mapping drive
+  the import shape).
+- OGAR = transpiler; lance-graph = Foundry execution. Tissue crates in the binary;
+  brain/engine crates out (BBB).
+- Canonical codebook is single-source: **pull, never re-mint** (drift-guarded by
+  `codebook_ids_match_ogar_vocab`).
+- SoC lint fires at `>= 256` members → branch.
+- No German PII; **no model/session identifier in any committed artifact**; audit
+  never egresses.
+
+## 8. First moves (ordered)
+
+1. Land **one Odoo model end-to-end** (e.g. `account.move` → `0x0202`): SPO →
+   `ModelGraph` → `Class` (via `schema_to_classes`) → mint with classid → facet,
+   with its FIBO/DOLCE grounding **retained** (Gap #2). Round-trip it.
+2. Do the **OpenProject twin** (`WorkPackage` → `0x0102`) — prove the agnostic
+   convergence (same concept, two app labels) on a real model, not just the test.
+3. Promote the grounding tuple on `CODEBOOK` (Gap #2) + the `MappingRow` FK (Gap #3).
+4. Then scale `odoo_blueprint` (the 404 entities) through the same path.
