From 183028814ab24a0700bb71dc6dd9b5f73b17f3d7 Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 19 May 2026 15:30:28 +0000 Subject: [PATCH 001/285] [woa] Add `woa_transcode_harvest` crate (Phase 0 skeleton) Additive crate that consumes `ruff_python_parser` + `ruff_python_ast` to emit per-route transcode bundles for the AdaWorldAPI/WoA -> woa-rs port. Does not modify any existing ruff crate; ruff and ty are unaffected. Phase 0 extracts route identity (endpoint, path, methods, function, source range, verbatim body) and decorator raw strings + kind classification. Phases 1-5 (auth/scope, ORM, templates, traps, port_status join) tracked in AdaWorldAPI/woa-rs:rfcs/v02-005-ruff-transcode-harvester.md. Canonical bundle schema lives in AdaWorldAPI/WoA:.claude/v0.2/PER_ROUTE_BUNDLE_SCHEMA.md. Verified end-to-end on real WoA blueprint: cargo run -p woa_transcode_harvest --bin woa-transcode -- \ harvest-one --rel woa/blueprints/vorgaenge_ops.py \ ../WoA/woa/blueprints/vorgaenge_ops.py Extracts two routes (wo_list GET /vorgaenge, wo_new GET+POST /vorgaenge/neu) with bodies verbatim and decorators classified.

Includes new src/ modules (config.rs, emit.rs, matcher/, preflight/, observations.rs), examples/flask.config.json, the JSON schema, and an extra config_parse_test. Does NOT compile against current ruff-upstream main. 5 errors: 1. src/emit.rs:129 — ? operator in eval_decorator_arg(...) -> Value (Value isn't Option/Result). Worker started returning Option-like semantics but the signature isn't there. 2. src/preflight/scanner.rs:208, 244 — if-let Expr::Call(...) = &e.value where e.value is Box. Worker wrote for &Expr but ruff types have Box-wrapped child slots; deref needed. 3. src/observations.rs:193 — match &Stmt missing Stmt::Assert variant (ruff AST drift since worker started). 4. src/observations.rs:318 — match &Expr missing Expr::TString and Expr::Slice variants (same drift).

Replaced with explicit let-else for the None case. 2. src/preflight/scanner.rs:208, 244 — pattern match if let Expr::Call(call) = &e.value where e.value is Box. Added explicit deref: if let Expr::Call(call) = &*e.value 3. src/observations.rs:193 — match on &Stmt missing Stmt::Assert variant. Added: walks .test, walks .msg if Some, emits 'Assert(N)' token (N = 1 + msg presence) — matches the rest of the walker's () shape. 4. src/observations.rs:318 — match on &Expr missing Expr::TString (PEP 750 template strings) and Expr::Slice. Added: - TString(n) where n = template-part count - Slice(n) where n = number of present {lower, upper, step} parts Both walk their child expressions before emitting the token. After fix: cargo check -p ruff_python_dto_check --all-targets -> 0 errors cargo test -p ruff_python_dto_check -> 0 passing, 0 failing (worker hadn't added the per-phase tests yet) Clippy is dirty (28 unique findings, mostly cast_possible_truncation from line-number arithmetic).

The original WIP commit 952fbd1 captured the broken state for audit; this commit ships the minimum to make the crate buildable again. --- crates/ruff_python_dto_check/src/emit.rs | 4 ++- .../ruff_python_dto_check/src/observations.rs | 31 +++++++++++++++++++ .../src/preflight/scanner.rs | 4 +-- 3 files changed, 36 insertions(+), 3 deletions(-) diff --git a/crates/ruff_python_dto_check/src/emit.rs b/crates/ruff_python_dto_check/src/emit.rs index df1706f68149f2..ed9cad5a2b4a3d 100644 --- a/crates/ruff_python_dto_check/src/emit.rs +++ b/crates/ruff_python_dto_check/src/emit.rs @@ -126,7 +126,9 @@ fn eval_decorator_arg(idx: usize, ctx: &FunctionContext<'_>) -> Value { let Expr::Call(call) = &ctx.matched_decorator.expression else { return Value::Null; }; - let arg = call.arguments.args.get(idx)?; + let Some(arg) = call.arguments.args.get(idx) else { + return Value::Null; + }; expr_to_value(arg, ctx.source) } diff --git a/crates/ruff_python_dto_check/src/observations.rs b/crates/ruff_python_dto_check/src/observations.rs index ce19e3b327b77c..665a36392a0816 100644 --- a/crates/ruff_python_dto_check/src/observations.rs +++ b/crates/ruff_python_dto_check/src/observations.rs @@ -311,6 +311,14 @@ fn walk_stmt(stmt: &Stmt, out: &mut String) { out.push_str(&format!("Match({})", 1 + m.cases.len())); } Stmt::IpyEscapeCommand(_) => out.push_str("IpyEscapeCommand(0)"), + Stmt::Assert(a) => { + walk_expr(&a.test, out); + if let Some(msg) = &a.msg { + walk_expr(msg, out); + } + let n = 1 + usize::from(a.msg.is_some()); + out.push_str(&format!("Assert({n})")); + } } } @@ -427,6 +435,29 @@ fn walk_expr(expr: &Expr, out: &mut String) { out.push_str("Named(2)"); } Expr::IpyEscapeCommand(_) => out.push_str("IpyEscape(0)"), + Expr::TString(t) => { + // Template strings (PEP 750) — emit token + part count. + // Detailed traversal would require ruff_python_ast::TStringPart; + // structural token is enough for the AST-hash heuristic. + let n = t.value.iter().count(); + out.push_str(&format!("TString({n})")); + } + Expr::Slice(s) => { + let mut n = 0usize; + if let Some(lower) = &s.lower { + walk_expr(lower, out); + n += 1; + } + if let Some(upper) = &s.upper { + walk_expr(upper, out); + n += 1; + } + if let Some(step) = &s.step { + walk_expr(step, out); + n += 1; + } + out.push_str(&format!("Slice({n})")); + } } } diff --git a/crates/ruff_python_dto_check/src/preflight/scanner.rs b/crates/ruff_python_dto_check/src/preflight/scanner.rs index 8a4ccc2764ad46..91adb62e2b3b88 100644 --- a/crates/ruff_python_dto_check/src/preflight/scanner.rs +++ b/crates/ruff_python_dto_check/src/preflight/scanner.rs @@ -205,7 +205,7 @@ impl PreflightScanner { } // Top-level `add_url_rule` and `register_blueprint` calls. if let Stmt::Expr(e) = stmt { - if let Expr::Call(call) = &e.value { + if let Expr::Call(call) = &*e.value { self.scan_call_for_blueprint_ops(rel, call, source); } } @@ -241,7 +241,7 @@ impl PreflightScanner { fn scan_for_add_url_rule(&mut self, rel: &str, stmt: &Stmt, source: &str) { if let Stmt::Expr(e) = stmt - && let Expr::Call(call) = &e.value + && let Expr::Call(call) = &*e.value { self.scan_call_for_blueprint_ops(rel, call, source); } From 5acd425b9159531d74ae57618de45f05ca013d10 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 20 May 2026 11:36:28 +0000 Subject: [PATCH 006/285] =?UTF-8?q?[dto-check]=20clippy=20cleanup=20?= =?UTF-8?q?=E2=80=94=2034=20findings=20(format=5Fpush=5Fstring/try=5Ffrom/?= =?UTF-8?q?doc/unused/expect)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit cargo clippy -p ruff_python_dto_check --all-targets --all-features -- -D warnings now green.

charset=UTF-8 Content-Transfer-Encoding: 8bit The crate has been generalized from its initial single-project shape into a config-driven extractor. This commit removes the last name-level references to that downstream project so the crate reads as a general tool for any Flask-shaped Python codebase. - README.md: rewrite the Quickstart / "Why a separate crate" sections; drop the "History" paragraph; show a generic per-file + per-tree invocation; reference examples/ and schemas/ for the canonical config. - src/lib.rs: drop the rename history doc-comment + downstream RFC ref; use a generic example path in the ModuleHarvest doc-comment. - src/bundle.rs: rephrase the legacy/config-driven distinction in the module doc-comment and section dividers without project-specific framing. - src/extractors/decorators.rs: prune the legacy hardcoded classifier to the two conventions (login_required, admin_required) needed by the golden test; drop downstream-specific decorator names entirely. Document that new code should drive classification from `config.match[].kind`. - bundle.rs::DecoratorKind: prune Scope + ModuleRequired variants; only Route/Auth/Other remain (the others were only produced by the downstream-specific names we just removed). - src/extractors/routes.rs: replace the cross-project script reference with an inline rule explanation. - examples/flask.config.json: generic include globs (`**/blueprints|routes|views/**/*.py`) and a generalized `family_from_filename` regex covering _ops / _bp / _routes / _views. - tests/golden_test.rs + tests/golden/flask_view.input.py: rename fixture; new test name flask_view_identity; generic Flask imports (flask_login.login_required); orders/Customer domain instead of the downstream-specific work-order vocabulary. - DESIGN.md: removed. It was an internal worker contract for the rename/refactor wave with deeply project-specific framing; the generalized README + the schema + AGENTS.md together cover what a contributor needs. Gates: cargo check / clippy -D warnings / fmt --check / test all green. flask_view_identity golden test still asserts the same shape on the new fixture. --- crates/ruff_python_dto_check/DESIGN.md | 448 ------------------ crates/ruff_python_dto_check/README.md | 110 +++-- .../examples/flask.config.json | 6 +- crates/ruff_python_dto_check/src/bundle.rs | 17 +- .../src/extractors/decorators.rs | 21 +- .../src/extractors/routes.rs | 7 +- crates/ruff_python_dto_check/src/lib.rs | 14 +- .../tests/golden/flask_view.input.py | 34 ++ .../tests/golden/wo_list.input.py | 36 -- .../tests/golden_test.rs | 21 +- 10 files changed, 148 insertions(+), 566 deletions(-) delete mode 100644 crates/ruff_python_dto_check/DESIGN.md create mode 100644 crates/ruff_python_dto_check/tests/golden/flask_view.input.py delete mode 100644 crates/ruff_python_dto_check/tests/golden/wo_list.input.py diff --git a/crates/ruff_python_dto_check/DESIGN.md b/crates/ruff_python_dto_check/DESIGN.md deleted file mode 100644 index 96f071a55d18e7..00000000000000 --- a/crates/ruff_python_dto_check/DESIGN.md +++ /dev/null @@ -1,448 +0,0 @@ -# `ruff_python_dto_check` — Generic Refactor Design Spec - -> Authored 2026-05-19 as the locked spec for the post-rename refactor. -> Branch: `claude/woa-transcoding-inventory-rSrhm` on `AdaWorldAPI/ruff`. -> Baseline: `origin/main @ 5ff5be9` (merged PR #1: Phase-0 Flask harvester). -> Rename commit: `9eba995` (woa_transcode_harvest → ruff_python_dto_check). -> Worker contract: single Sonnet worker, isolation=worktree, sentinel token below. - ---- - -## §1 Status & Baseline - -Crate is currently a **Flask-specific route harvester** (originally -`woa_transcode_harvest`).

Now compiles a GlobSet from each list (empty list = no filter, distinct from empty set that matches nothing) and applies include-then-exclude to each candidate's rel-path before reading the file. 2. attach_observations was never invoked, so every emitted bundle carried comparison_within_family: None and indices/by_ast_hash.json was empty for every run. Now: stash the source per harvested file into a source_map, then call attach_observations between the per-family sort and write_family_bundles. Tests added: - tests/observations_attach_test.rs: lib-level regression — runs matcher on a 3-route fixture, asserts pre-attach bundles have None, asserts post-attach every bundle has comparison_within_family with family_size and sha256: ast_hash_self populated. - src/bin/ruff_py_dto.rs #[cfg(test)] mod tests: 5 unit tests for build_glob_set (empty -> None, invalid -> Err) and path_passes_filters (include-only, exclude-only, exclude-wins-over-include, no-filters).

Pages with no {% for %} block keep the faithful skeleton. Task B: add the remaining 11 handler-kinds as KindRecipe variants + emit arms (detail_for_tenant, template_get, toggle_bool_field, get_redirect_shortcut, csrf_form_post_engine_call, form_get_post, ajax_json, download_blob, pdf_render, sa_admin_view, signed_link_action). Form-bearing kinds emit a Deserialize form DTO from inputs.form_fields (shape ported from contracts_to_rust.py, codegen/dto.rs). Model paths stay single-segment flat / nested ERP (no Sonnet doubling); pdf_render emits the call-site shape with a documented stub for the PDF byte source — never todo!() in a compiled path.

Threaded contract.inputs.path_params into the 11 emitter call sites; dropped the now- dead name-only locals. - P1 TOML inline comments: toml_lite::strip_comment used a "no quote before #" heuristic that left the comment in the value for every quoted field (id = "x" # c). Replaced with an in-string state scan; `#` inside a quoted value stays part of the value. - P2 body extraction: the try-walker visited body + handlers but skipped orelse/finalbody, mis-classifying OutputKind for handlers that return from else/finally. Now walks both. Unit tests added for the two P1s (converter→type map incl. bare=String; inline-comment-after-quoted-value via parse_target). 59 tests green; clippy --all-targets -D warnings clean. https://claude.ai/code/session_01QJLaW8KoobZdT1fNt4YUVb --- .../ruff_python_dto_check/src/codegen/mod.rs | 100 +++++++++++++----- .../src/codegen/target.rs | 35 +++++- .../src/extractors/body.rs | 8 ++ 3 files changed, 115 insertions(+), 28 deletions(-) diff --git a/crates/ruff_python_dto_check/src/codegen/mod.rs b/crates/ruff_python_dto_check/src/codegen/mod.rs index 982bc0beccd0f0..54cd4b49b9a0b4 100644 --- a/crates/ruff_python_dto_check/src/codegen/mod.rs +++ b/crates/ruff_python_dto_check/src/codegen/mod.rs @@ -455,7 +455,7 @@ fn emit_soft_delete(contract: &RouteContract, spec: &TargetSpec) -> Emitted { let column = mapping.column_path(&spec.models_root); let model_use = format!("crate::models::{}", mapping.module_path); let primary_param = params.first().copied().unwrap_or("id"); - let param_sig = param_signature(¶ms); + let param_sig = param_signature(&contract.inputs.path_params); let scope_filter = if contract.data.tenant_scoped || contract.guards.iter().any(|g| g.contains("get_owned")) @@ -553,13 +553,37 @@ fn emit_soft_delete(contract: &RouteContract, spec: &TargetSpec) -> Emitted { } } -fn param_signature(params: &[&str]) -> String { - match params.len() { - 0 => String::new(), - 1 => format!(" Path({}): Path,\n", params[0]), +/// Map a Flask path converter to the Rust extractor type.

The closed triple vocabulary + the deterministic expander, factored out of the Odoo extraction: - `Triple { s, p, o, f, c }` — mirrors lance_graph's OntologyTriple field-for-field so emitted ndjson loads into the SPO store with no transform. - `Predicate` (7 variants: rdf:type, has_function, emitted_by, depends_on, reads_field, raises, traverses_relation) — closed vocabulary, frontends never emit raw strings. - `EntityKind` (ObjectType/Property/Function) → canonical `ogit:` IRIs (http://www.purl.org/ogit/, not a project-local namespace). - `Provenance` (Structural 1.0/1.0, Authoritative 0.95/0.90, Inferred 0.85/0.75) — the NARS truth calibration from the Odoo harvest. - `ModelGraph` IR — the neutral struct a frontend fills (namespace + models + fields + functions). This is the reuse seam: AST→IR is the only per-language work; IR→triples is shared. - `expand(&ModelGraph) -> Vec` — deterministic (sorted by (s,p,o), de-duplicated, truth-weighted per predicate). - `to_ndjson` / `from_ndjson` — the on-disk format the lance_graph loader reads; parse fails loud with the offending line number. 15 tests: predicate round-trip, truth-tier calibration, full predicate-class expansion, determinism, dedup, ndjson round-trip, malformed-line reporting, two-model integration. A compiling skeleton that targets the OpenProject extraction: - `extract(&Path) -> ModelGraph` with `todo!()` at each parser plug-in point, each documented with the exact Rails construct to read (ActiveRecord associations → traverses, validations → raises, memoized methods → emitted_by, schema.rb columns → fields). - A locked-shape test that passes TODAY: builds a hand-written WorkPackage ModelGraph and asserts the expand() output, so the target triple shape is pinned before the parser is wired. - Recommends lib-ruby-parser (pure-Rust typed AST); no external parser dep pulled in yet so the shape can be locked first. `crates/ruff_spo_triplet/SPO_TRIPLET_EXTRACTION.md` — the full methodology for the other session: triple schema, provenance calibration, the IR contract, the "a + b -> c through d" compute-graph query, and a step-by-step Ruby/Rails frontend guide with the complete Rails-construct -> IR mapping table. Both crates: zero warnings, rustfmt-clean, additive (touch no existing crate). Workspace members = ["crates/*"] auto-includes them; two workspace.dependencies entries added. --- Cargo.toml | 2 + crates/ruff_ruby_spo/Cargo.toml | 23 ++ crates/ruff_ruby_spo/src/lib.rs | 215 +++++++++++++ crates/ruff_spo_triplet/Cargo.toml | 18 ++ .../SPO_TRIPLET_EXTRACTION.md | 252 +++++++++++++++ crates/ruff_spo_triplet/src/expand.rs | 302 ++++++++++++++++++ crates/ruff_spo_triplet/src/ir.rs | 103 ++++++ crates/ruff_spo_triplet/src/lib.rs | 110 +++++++ crates/ruff_spo_triplet/src/ndjson.rs | 124 +++++++ crates/ruff_spo_triplet/src/triple.rs | 264 +++++++++++++++ 10 files changed, 1413 insertions(+) create mode 100644 crates/ruff_ruby_spo/Cargo.toml create mode 100644 crates/ruff_ruby_spo/src/lib.rs create mode 100644 crates/ruff_spo_triplet/Cargo.toml create mode 100644 crates/ruff_spo_triplet/SPO_TRIPLET_EXTRACTION.md create mode 100644 crates/ruff_spo_triplet/src/expand.rs create mode 100644 crates/ruff_spo_triplet/src/ir.rs create mode 100644 crates/ruff_spo_triplet/src/lib.rs create mode 100644 crates/ruff_spo_triplet/src/ndjson.rs create mode 100644 crates/ruff_spo_triplet/src/triple.rs diff --git a/Cargo.toml b/Cargo.toml index 03b948d730b889..be4d42dbe5f816 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -40,8 +40,10 @@ ruff_python_parser = { version = "0.0.17", path = "crates/ruff_python_parser" } ruff_python_semantic = { version = "0.0.17", path = "crates/ruff_python_semantic" } ruff_python_stdlib = { version = "0.0.17", path = "crates/ruff_python_stdlib" } ruff_python_trivia = { version = "0.0.17", path = "crates/ruff_python_trivia" } +ruff_ruby_spo = { path = "crates/ruff_ruby_spo" } ruff_server = { version = "0.0.17", path = "crates/ruff_server" } ruff_source_file = { version = "0.0.17", path = "crates/ruff_source_file" } +ruff_spo_triplet = { path = "crates/ruff_spo_triplet" } ruff_mdtest = { path = "crates/ruff_mdtest" } ruff_ranged_value = { version = "0.0.17", path = "crates/ruff_ranged_value" } ruff_text_size = { version = "0.0.17", path = "crates/ruff_text_size" } diff --git a/crates/ruff_ruby_spo/Cargo.toml b/crates/ruff_ruby_spo/Cargo.toml new file mode 100644 index 00000000000000..805950b364d5e7 --- /dev/null +++ b/crates/ruff_ruby_spo/Cargo.toml @@ -0,0 +1,23 @@ +[package] +name = "ruff_ruby_spo" +version = "0.1.0" +publish = false +edition = "2024" +rust-version = "1.86" +description = "SCAFFOLD: Ruby/Rails (OpenProject) frontend for ruff_spo_triplet.

The mapping (mirror of the Odoo column in the +cheat-sheet in `src/ir.rs`): + +| IR target | Rails / ActiveRecord source | +| --- | --- | +| `Model::name` | `class WorkPackage < ApplicationRecord` → `WorkPackage` | +| `Field::name` | DB columns (from `db/schema.rb`), `attribute :x`, `attr_accessor`, `store_accessor` | +| `Field::depends_on` | association chains a derived attribute reads (`time_entries.hours`); if you parse `schema.rb` you can also seed column→column deps | +| `Field::emitted_by` | a memoized/derived method that assigns the attribute (`def total_hours; @total_hours ||= …; end`) | +| `Function::name` | instance methods (`def compute_total_hours`) | +| `Function::reads` | `self.x` reads and bare attribute reads in the method body | +| `Function::raises` | `raise X`, `errors.add(...)`, and `validates`/`validate` callbacks (treat the validation as a guard that raises `ActiveRecord::RecordInvalid`) | +| `Function::traverses` | association walks in the body (`children.each`, `time_entries.map`, `project.members`) — the association name is the relation | + +Notes specific to Rails: + +- **Associations are your relations.** `belongs_to :project`, + `has_many :time_entries` declare the traversable relations. A method + body that calls `time_entries` is traversing `time_entries`. Seed the + set of valid relation names from the association declarations so you can + distinguish a relation walk from an ordinary method call. +- **Validations are guards.** `validates :subject, presence: true` and + `validate :custom_check` are the Rails analogue of Odoo's + `@api.constrains` + `raise`. Emit them as `raises exc:ActiveRecord::RecordInvalid` + (Authoritative) on the validating method, or on a synthetic + `_validate` function for declarative `validates`. +- **`exc:` namespace is shared.** Ruby exception class names keep their + `::` (`exc:ActiveRecord::RecordInvalid`) — the `exc:` prefix is the same + one Odoo uses (`exc:UserError`). Don't translate; just prefix. +- **Callbacks (`before_save`, `after_create`) → functions** whose + `traverses`/`reads`/`raises` you extract from the referenced method. + +### Step 3 — build the `ModelGraph` + +```rust +let mut graph = ModelGraph::new("openproject"); +for class in rails_classes { + let mut model = Model::new(normalise(&class.name)); + model.fields = extract_fields(&class); // step 2 + model.functions = extract_functions(&class); // step 2 + graph.models.push(model); +} +``` + +### Step 4 — expand + write + +```rust +use ruff_spo_triplet::{expand, to_ndjson}; +let triples = expand(&graph); // sorted, de-duplicated, truth-weighted +std::fs::write("openproject.spo.ndjson", to_ndjson(&triples))?; +``` + +### Step 5 — load downstream (already built, no new work) + +The ndjson loads directly into `lance_graph::graph::spo::odoo_ontology::load_ontology` +(rename or generalise that loader's name; the *format* is identical). +`action_emitter::emit_actions` and `link_chain::split_all_depends_on` +then work on the OpenProject graph exactly as they do on Odoo's. + +--- + +## 6. The scaffold crate (`ruff_ruby_spo`) + +`crates/ruff_ruby_spo/` is a compiling skeleton: + +- depends on `ruff_spo_triplet`, +- exposes `extract(source_tree: &Path) -> ModelGraph`, +- has `todo!()` bodies at each of the step-2 extraction points with a + doc-comment naming the exact Rails construct to read, +- ships a unit test that builds a hand-written `ModelGraph` and asserts + the `expand()` output — so the *target shape* is locked even before the + parser is wired. + +Start there: replace the `todo!()`s one predicate at a time, running the +locked-shape test after each. When all are filled, point it at the +OpenProject `app/models/` tree. + +--- + +## 7. Verifying parity with the Odoo extraction + +Two graphs are "the same shape" if, for a structurally-equivalent input, +they produce the same predicate histogram and the same truth tiers. The +crate's own tests pin this: + +- `triple::tests::provenance_truth_tiers_match_odoo_calibration` +- `expand::tests::truth_tiers_are_assigned_per_predicate` +- `integration_tests::two_model_graph_round_trips_through_ndjson` + (uses a Rails-shaped `ModelGraph`) + +When you wire the Ruby frontend, add a fixture test that runs a small +real OpenProject model through `extract()` + `expand()` and asserts the +expected `ActionSpec` shape downstream. That closes the loop: same IR +contract → same triples → same Foundry-shape actions. + +--- + +## 8. Pointers + +- `src/triple.rs` — the closed vocabulary (`Predicate`, `EntityKind`, `Provenance`). +- `src/ir.rs` — the `ModelGraph` contract + the Odoo↔Rails cheat-sheet. +- `src/expand.rs` — the deterministic IR→triples projection. +- `src/ndjson.rs` — the on-disk format (matches the `lance_graph` loader). +- Downstream consumers (in the `lance-graph` repo): + `crates/lance-graph/src/graph/spo/odoo_ontology.rs` (loader), + `…/action_emitter.rs` (Foundry `ActionSpec` composer), + `…/link_chain.rs` (dotted-path splitter). diff --git a/crates/ruff_spo_triplet/src/expand.rs b/crates/ruff_spo_triplet/src/expand.rs new file mode 100644 index 00000000000000..97ce7deecb01b2 --- /dev/null +++ b/crates/ruff_spo_triplet/src/expand.rs @@ -0,0 +1,302 @@ +//!

A typo like `depend_on` (missing the `s`) parsed as a well-formed Triple but then disappeared silently from every downstream `depends_on` query — the exact silent-corruption failure mode the closed-vocabulary contract is meant to prevent. Fix: after the JSON shape check, validate `t.p` through `Predicate::from_str`. On failure, return `ParseError` with a message that echoes the offending predicate and lists the seven valid ones, so the corrupt-emit source is obvious. The `to_ndjson` side already enforces the vocabulary at the type level (`Triple::new` takes `Predicate`, not `String`), so this only adds a gate on the parse side. The asymmetry is intentional — emit is closed by construction; parse is the boundary that ingests untrusted bytes. Two new tests: `unknown_predicate_is_rejected` pins the new gate; `every_canonical_predicate_parses` guards against `from_str` drifting away from `as_str` over time. 17 tests green (was 15 + 2 new).

The added 27 cover every class-body DSL category measured on the OpenProject corpus (941 models / 1696 declarations / 78 distinct names → 67 emit categories + 11 scope markers). New predicates by category: - associations: declares_association - validations: validates_constraint, normalizes_attribute - callbacks: has_callback (phase encoded in object slot) - concerns: includes_module, extends_module, prepends_module, concern_class_methods, concern_included_block - attributes: has_attribute, aliases_attribute, aliases_method, column_override - delegation: delegates_to - scopes: has_scope, has_default_scope - acts_as_* family: acts_as - OP custom DSL: registers_journal_formatter, registers_journal_formatted_fields, has_dsl_call (catch-all) - third-party gem DSL: mounts_uploader, has_paper_trail, has_closure_tree, counter_cultures, auto_strips - metaprogramming: defines_method - refinements: uses_refinement `Provenance::OpenProjectExtracted = (0.95, 0.88)` is hand-tuned per `I-NOISE-FLOOR-JIRAK`: same frequency as `Authoritative` (Odoo `@api.depends` ≈ Ruby `belongs_to :project` in truth-functional certainty), confidence two NARS revision-counts lower to encode the Ruby metaprogramming surface delta. Two per-edge overrides: `defines_method` defaults to `Inferred` (dynamic = heuristic); `concern_class_methods` / `concern_included_block` carry `Structural` (block declarations are structural-by-construction). `Predicate::ALL` is a new const slice that enumerates every variant in canonical order; the closed-vocab round-trip test iterates over it, so adding a variant without updating `ALL` fails loudly. ## D-AR-2 — Model IR expansion + RubyClass declarations `ruff_spo_triplet::Model` grows 12 new `Vec<…>` fields + 1 `Option` field — one slot per emit category. `ModelGraph` itself adds zero new fields (per prior-art-savant Round 1 ACK: additions-only, no new trait, `expand()` stays a free fn over IR structs). `ruff_ruby_spo::RubyClass.associations: Vec` becomes `RubyClass.declarations: Vec` — a frontend-local discriminated union over the 13 categories. The `extract()` fn unpacks declarations into the typed `Model::*` slots; no `body_source` re-parsing (per prior-art-savant REJECT of smuggling). ## expand() — 13 new emission arms The `Expander` struct holds the dedup `BTreeSet` + accumulator and provides one method per Model sibling field. The new arms are mechanical projections (one or two `push` calls each), so the function stays a pure projection and determinism is preserved (sorted by `(s, p, o)`, dedup by identity, truth not in key). ## Acceptance tests - 36 tests in `ruff_spo_triplet` (was 14): predicate round-trip over all 34, default_provenance exhaustiveness, the AR-shape `Declaration → Triple` expansion for every new field type. - 3 tests in `ruff_ruby_spo` (was 2): the existing locked-shape test still passes, plus a new `declarations_unpack` test that guards the frontend→IR seam against drift if a new Declaration variant is added without a routing arm. - `predicate_count_locked_at_34` and the per-AR-predicate emission check (`ar_shape_emits_every_ar_predicate`) gate the closed vocab + the expander coverage atomically. ## Council gate dto-soa-savant + truth-architect Round-1 ACK on D-AR-1; prior-art- savant + integration-lead Round-1 ACK on D-AR-2 + the PR shape (single PR for vocab + IR + expansion-test atomically).

Replaces the `todo!()` scaffold in `ruff_ruby_spo` with a real AST-based extractor (operator-locked direction: lib-ruby-parser, not the line scanner) and ships the D-AR-4 100%-coverage gate. `lib-ruby-parser = "4.0"` (default-features = []) — pure-Rust typed AST, no Ruby runtime. Two new modules in `ruff_ruby_spo`: - `parse.rs` (~190 LOC): walks `/app/models/**/*.rb`, parses each file once with `lib_ruby_parser::Parser::new(...).do_parse()`, finds `Node::Class` definitions (recursing into `Node::Module` namespace wrappers + `Node::Begin` statement blocks). Reads the superclass and records non-canonical parents (anything other than `ApplicationRecord` / `ActiveRecord::Base` / `Object`) as `Declaration::Sti`. Returned classes are sorted by file path for determinism. - `walk.rs` (~390 LOC): the routing core. Takes a `Class.body` node and dispatches each top-level `Send` call (no receiver) to a `Declaration` variant by method-name match. The 78-name closed vocab from the §2 census on lance-graph maps onto a single `route_send(name, args, out)` match: - 5 association macros → `Declaration::Association` - 5 validation macros → `Declaration::Validation` - 13+ callback phases (allow-list) → `Declaration::Callback` - `include`/`extend`/`prepend` → `Declaration::Concern` - `class_methods do`/`included do` block forms (in `walk_block`) → `Declaration::Concern` with body_ref - 13 attribute macros → `Declaration::Attribute` - `delegate` → `Declaration::Delegation` - `scope` (lambda and do-block forms) / `default_scope` / `scopes` (OP plural) → `Declaration::Scope` - `acts_as_*` (prefix match) → `Declaration::ActsAs` - 5 OP custom registrations + catch-all → `Declaration::DslCall` - 5 third-party gem DSLs → `Declaration::GemDsl` - `define_method` → `Declaration::DynamicMethod` - `using` → `Declaration::Using` - Visibility scope markers (`private`, `protected`, `public`, `private_class_method`, `private_constant`, `class_attribute`, `module_function`) consumed silently (per §2 they are not emit categories) - Long-tail catch-all `_ => DslCall` — every method name not yet discriminated still produces a Declaration, so "Unclassified" count is structurally zero. `Send`-with-Lambda-arg vs `Block`: the `->` lambda form (`scope :n, -> { ... }`) parses as a `Send` with a `Lambda` arg, NOT a `Block`, so scope/default_scope have BOTH `route_send` arms (lambda-arg) and `walk_block` arms (do-block). Tested both ways. `extract_fields` / `extract_functions` are D-AR-3 stubs returning empty Vec — the D-AR-4 gate measures *declarations*, not field / function depth. Their full implementations land in follow-up D-AR-3.5 (docstrings point at the TODO + the Rails→IR mapping preserved from the pre-21c828d scaffold). Three layers: 1. **Synthetic fixture** (`ar_shape_synthetic_fixture_exercises_every_declaration_variant`): a single Ruby class hand-crafted to hit every `Declaration` variant. Asserts: 5 associations / 3 validations / ≥1 callback / ≥3 concerns / 4 attributes / 1 delegation / ≥4 scopes / 2 acts_as / ≥4 dsl_calls / 2 gem_dsl / 1 dynamic_method / 1 using / 1 sti. Hermetic — runs in `cargo test` without any external corpus. 2. **Routing-table lock** (`ar_shape_dsl_catchall_does_not_steal_discriminated_names`): a source with one call per discriminated DSL name + one genuinely- unknown DSL. Asserts that none of the 38 discriminated §2 names leak into the `has_dsl_call` catch-all and that the unknown one IS captured by the catch-all. This is the routing-correctness gate. 3. **Real-corpus gate** (`ar_shape_real_corpus_coverage_gate`): conditional on the `OPENPROJECT_PATH` env var. When run against `/home/user/openproject`, the gate observes: - **694 classes** extracted (file baseline = 941; the gap is module-only files which contribute zero classes), - **2299 declarations** total (§2 census measured 1696 — my count is higher because `attr_accessor :a, :b, :c` becomes 3 AttrDecls vs 1 source-line, and similar multi-arg expansions), - **0 leaked discriminated names** into `has_dsl_call`. `ruff_ruby_spo`: 3 → 6 tests (+3). - `ar_shape_synthetic_fixture_exercises_every_declaration_variant` - `ar_shape_dsl_catchall_does_not_steal_discriminated_names` - `ar_shape_real_corpus_coverage_gate` (passes when corpus available; no-op without `OPENPROJECT_PATH`) ```text running 6 tests test result: ok. 6 passed; 0 failed; 0 ignored D-AR-4 corpus gate: 694 classes, 2299 declarations, 0 leaked names ``` Zero new warnings in `ruff_ruby_spo`. The 2 pre-existing warnings on `ruff_spo_triplet` (already in main from PR #5) are unchanged. The catch-all `_ => DslCall{ name, args }` arm in `route_send` is the structural reason "Unclassified = 0" by construction. Routing *correctness* (discriminated names not leaking to catch-all) is asserted by both the synthetic and real-corpus tests. D-AR-4 status: **PASSED on the OpenProject corpus** as measured in this commit. Follow-up D-AR-3.5 will add `extract_fields` / `extract_functions` body extraction for the Field/Function side (orthogonal to declaration coverage). --- crates/ruff_ruby_spo/Cargo.toml | 11 +- crates/ruff_ruby_spo/src/lib.rs | 480 ++++++++++++++++++++----- crates/ruff_ruby_spo/src/parse.rs | 194 ++++++++++ crates/ruff_ruby_spo/src/walk.rs | 563 ++++++++++++++++++++++++++++++ 4 files changed, 1156 insertions(+), 92 deletions(-) create mode 100644 crates/ruff_ruby_spo/src/parse.rs create mode 100644 crates/ruff_ruby_spo/src/walk.rs diff --git a/crates/ruff_ruby_spo/Cargo.toml b/crates/ruff_ruby_spo/Cargo.toml index 805950b364d5e7..01950719a22dec 100644 --- a/crates/ruff_ruby_spo/Cargo.toml +++ b/crates/ruff_ruby_spo/Cargo.toml @@ -13,11 +13,12 @@ name = "ruff_ruby_spo" [dependencies] ruff_spo_triplet = { workspace = true } -# TODO(frontend): add a Ruby parser when wiring real extraction.

Mirrors `ruff_ruby_spo::tests::locked_shape_expands_to_expected_triples`. Land this *before* wiring libclang. +- **`clang` crate wiring** — `Cargo.toml` dep + minimal walker that walks one Tesseract translation unit (e.g. `tesseract/src/api/baseapi.h`) and produces the locked shape. +- **Predicate vocab extension** — C++-flavored predicates (see `ruff_cpp_spo-handover.md` §3 and `ruff_cpp_headstone.md` "closed-vocab predicate set when complete" for the target list). Land them in `ruff_spo_triplet::Predicate` under the `predicate_count_locked_at_N` gate. +- **`Provenance::CppExtracted`** — calibrated against a Tesseract corpus baseline; initial target `(0.95, 0.82)`. +- **`tesseract-rs` cleanup** — any C++ source still vendored from the previous attempt must be removed. Salvageable Rust glue (if any) preserved under `legacy/`. +- **First codegen run** — once `ruff_cpp_spo` emits IR for a Tesseract subset, the lance-graph codegen plan consumes it and produces Rust files into `tesseract-rs`. + +--- + +## Iron rules (fail loudly if violated) + +1. **No C++ source inside `tesseract-rs`.** Single most concrete rule. The previous attempt failed it. `-rs` is a Rust target. C++ corpus stays at `tesseract-ocr/tesseract` upstream (or a pinned external corpus location). +2. **No new `ValueSchema` enum variant.** Per `lance-graph` PR #500's enforced contract test `ocr_schema_fit_rides_existing_preset_no_new_variant`. C++ rides `Full` / `Compressed` via `classid → ClassView`. +3. **`HelixResidue` width is 6 bytes** (the stored `Signed360` place index). Pre-#498 docs may say 48; that's a bits-bytes slip. Don't propagate. +4. **Locked-shape test before parser wiring.** `ruff_ruby_spo` PR #4 is the template — hand-build the `ModelGraph`, assert `expand()`, then wire `clang` crate. +5. **`ruff_spo_triplet` stays serde-only.** The libclang dependency lives in `ruff_cpp_spo`, never in the shared core. +6. **No re-parsing of source in `extract()`.** Frontend-local declarations get unpacked into shared `ModelGraph` slots via `unpack_declaration`. Mirror PR #5's discipline. +7. **`predicate_count_locked_at_N`** test enforces closed-vocab. Adding a variant without updating `Predicate::ALL` fails loudly. Land it for C++ extensions too. +8. **No model identifier in committed artifacts** (per workspace canon). + +--- + +## First moves (suggested sequence) + +1. **Check the state of both repos.** What's already in `ruff/crates/ruff_cpp_spo/`? What's in `tesseract-rs/` from the previous attempt? Inventory before changing anything. +2. **Decide the corpus pin.** Tesseract upstream `tesseract-ocr/tesseract` HEAD or a pinned tagged release. Record the decision in the codegen plan. +3. **`tesseract-rs` cleanup** if any C++ source from the previous attempt remains. PR with explicit *"retiring previous-attempt C++ vendoring per the headstone discipline"* commit message. Either preserve Rust glue under `legacy/` or remove cleanly. +4. **`ruff_cpp_spo` scaffold** — new crate with `Cargo.toml`, `lib.rs`, `extract.rs` (with `todo!()` at parser plug-in), `tests/` with the locked-shape test. +5. **Hand-build a `ModelGraph`** for `Tesseract::Recognizer` (or similar representative class) with 5-10 declarations. Assert `expand(&graph)` output. Test should pass before libclang wiring. +6. **Wire `clang` crate** as the parser. Walk one Tesseract TU. Compare output against the locked shape. +7. **Predicate vocab expansion** — add the C++-flavored predicates under the locked-count gate. +8. **First ndjson emission** — walk a Tesseract subset, emit to a file, load into `lance-graph` SPO store. +9. **Hand-off to the codegen plan** — `lance-graph`'s `tesseract-rs-ast-dll-codegen-v1` plan consumes your IR and produces Rust source. +10. **Spec the gating probes** — `CPP-AST-RT` (libclang AST round-trip), `CPP-TEMPLATE-DET` (template instantiation determinism), `CPP-SCHEMA-FIT` (predicate vocab coverage). Don't claim FINDING-grade fidelity without these. + +--- + +## When to stop and ask + +These are genuine operator-only decisions: + +- **The Tesseract release pin.** Don't guess; ask. +- **Cleanup vs preservation of any pre-existing `tesseract-rs` content.** If there's anything non-trivial, ask before deleting. +- **Whether to add a probe / `Provenance` tier / new predicate** that doesn't have a direct precedent in Python or Ruby vocab. Ask before extending. +- **Hand-off boundary with `tesseract-rs-ast-dll-codegen-v1`.** Does `ruff_cpp_spo` stop at IR + triples emission (as `ruff_ruby_spo` does), or also drive the codegen step (as `ruff_python_dto_check` does)? +- **If `ocrs + rten` un-parks** during your session and there's an apparent overlap — confirm with the operator that the two paths still coexist; they're orthogonal but a fresh operator decision may reshape priorities. + +--- + +## Discipline reminders (from prior session's failure modes) + +- **Search the workspace, not just your transcript.** When you can't recall a term, grep the repos first. The transcript is a slice; the workspace is canon. +- **Verify the substrate before citing a name.** Don't claim *"X inherits Y's property"* without checking that X runs Y's algorithm. Shared bit-width is not shared algorithm. +- **Before any new column / tenant / variant proposal:** check whether the substrate has institutionalised *"no new variant"* (e.g. `ocr_schema_fit_rides_existing_preset_no_new_variant`). If yes, ride existing presets. +- **Five-specialist drift-catching pass** (`cascade-architect` / `family-codec-smith` / `palette-engineer` / `dto-soa-savant` / `truth-architect`) before any FINDING-grade claim.

The previous emission attributed edges to non-existent methods. New helper `delegate_prefix(d)` resolves the option to the actual exposed-method prefix: - `prefix: true` → use `d.to` as the prefix - `prefix: :owner` / `prefix: "owner"` → use literal `"owner"` - `prefix: false` / absent → no rename ## ruff_ruby_spo::parse — module namespace (PR #6 r…) `module Foo; class Bar < ApplicationRecord; end; end` now emits `name = "Foo::Bar"` instead of just `"Bar"`. The previous walker dropped the enclosing module names, so two distinct namespaced models with the same inner class name would collide in the SPO graph. `collect_classes_from_node` now threads a `ns: &[String]` stack through the recursion; `Module` arms push onto the stack; `Class` arms qualify the local name with `ns.join("::")`. ## ruff_ruby_spo::walk — scoped association options (PR #6 r…) `has_many :items, -> { active }, dependent: :destroy` puts the options at args[2] (the lambda is args[1]). `emit_assoc` now scans ALL args (skipping arg[0] = name) via `find_map(as_hash_options)` instead of just checking args[1]. Also: `as_hash_options` now accepts `Node::Kwargs` (trailing `k: v, k2: v2` keyword args), not just `Node::Hash` (literal `{}`). This is what lib-ruby-parser actually emits for Ruby macro kwargs. ## ruff_ruby_spo::walk — attribute metadata args (PR #6 r…) `attribute :age, :integer` no longer emits a bogus `integer` attribute. The generic emit-one-per-symbol loop is replaced by a per-AttrKind `(skip, take)` window: - `attribute :age, :integer` → take args[0] only (1 attr) - `attr_accessor :a, :b, :c` → take all positional syms (N attrs) - `serialize :data, JSON` → take args[0] only - `store_accessor :store, :a, :b, :c` → skip args[0] (store key), take args[1..] (N attrs) - `store_attribute :store, :attr, :type` → skip args[0], take args[1] only - `define_attribute_method :attr` → take args[0] only ## ruff_ruby_spo::walk — with_options wrapper block (PR #6 r…) `with_options presence: true do; validates :name; end` no longer loses the inner validations. The block-form walker now has a dedicated `with_options` arm that recurses into the block body (walk_class_body) so inner declarations land on the model. The arbitrary-generic-block arm continues to NOT recurse to avoid double-counting from runtime blocks like `5.times do ... end`. ## ruff_ruby_spo::walk — alias keyword (PR #6 r…) Ruby's `alias new_name old_name` keyword form parses as `Node::Alias`, NOT as a `Send`. The walker now recognises it and emits `Attribute::Alias` with `name = "new=old"`. The original scaffold dropped these entirely. # Tests `ruff_spo_triplet`: 36 → 37 (+1 `delegate_prefix_option_shapes`). `ruff_ruby_spo`: 6 → 12 (+6 codex regression tests): - module_namespace_qualifies_inner_class_name - scoped_association_picks_up_trailing_options - attribute_macro_does_not_emit_type_as_attribute - store_accessor_does_not_emit_store_key_as_attribute - with_options_grouping_block_recurses_into_body - ruby_alias_keyword_emits_alias_declaration `ar_shape_expands_delegation_to_one_triple_per_method` updated to assert the new (correct) prefixed-method emission AND that the un-prefixed form does NOT appear. # Real-corpus gate `OPENPROJECT_PATH=/home/user/openproject cargo test ar_shape_real_corpus_coverage_gate` now reports: D-AR-4 corpus gate: 694 classes, 2261 declarations, 0 leaked names Was 2299 declarations before — the 38-attribute drop matches the expected reduction from removing bogus `:integer`/`:JSON`/store-key attributes (the codex fix's actual signal). # Clippy Zero new warnings.
