\\n\\n`@PhysShell` Read the doc end to end plus cross-checked the claims against `ownlang/analysis.py`, `ownlang/diagnostics.py`, `ownlang/evidence.py`, and `ownlang/codegen.py`. This is a genuinely well-argued bird's-eye plan — the strongest part is that the oracle rides on contracts you already froze (SARIF/evidence) rather than internal state. Pushback per prompt:\\n\\n### 1. Crate DAG / coupling\\n\\nThe `own-analysis → own-diagnostics` edge is actually *validated* by the current code: `ownlang/analysis.py` (Lines 239–262, 605–673) constructs `Evidence` — a type owned by `ownlang/diagnostics.py` — using solver-internal state (`st`, `rid`, line lookups). So the dependency correctly points from the solver toward the verdict/data type, not the reverse. Good sign the invariant will hold in Rust too (own-analysis depends on the `Evidence`/`Diagnostic` structs from own-diagnostics; own-diagnostics never reaches back into `Lattice`/worklist internals).\\n\\nBut I think the diagram has one edge that doesn't match reality: **`own-diagnostics ──▶ own-codegen`**. In the Python core, `codegen.generate(mod: A.Module)` (`ownlang/codegen.py:792`) takes only the AST — it never imports `diagnostics.py` or consumes `Diagnostic`/`Evidence`. Codegen is decided purely from AST-level shape (`_fn_has_buffer`, `_laminar_scopes`, `_buffer_modes`, etc.), not from analysis verdicts. If that stays true in Rust, `own-codegen` should depend on `own-cfg`/AST types directly, and the \\\"verdict-independent codegen\\\" fact is worth stating explicitly rather than implied by a diagram edge that suggests codegen is downstream of diagnostics. If Rust codegen *does* eventually want ownership verdicts (e.g., inserting a generated `Dispose()` based on the solver's own conclusions rather than re-deriving policy from AST shape), that's a deliberate new coupling worth flagging separately — don't let it sneak in through the diagnostics layer just because the arrow already points that way in the doc.\\n\\n### 2. Dataflow state representation\\n\\nAgree persistent maps are the right *default* to reach for, but bench against arena+generational-index CoW before committing, because:\\n- `imbl`/`rpds` win when merges are frequent and sharing is high (wide CFGs, many join points) — structural sharing amortizes well.\\n- A dense arena with a \\\"dirty\\\" bitset + copy-on-write clone wins when the analysis is mostly linear (few merges) and state is small per-RID, since persistent-map lookup has a real per-access constant-factor cost that a flat `Vec` doesn't.\\n- Given the doc's own description of the analyses (ownership/lifetime/effect/DI) as fairly *procedural* with modest branching per function (not the wide, deeply-nested CFGs of a whole-program solver), I'd bet the arena+CoW wins on this workload, and `imbl` wins only if you graduate to interprocedural/whole-program dataflow later. Benchmark on the corpus's largest real function (not synthetic), and measure both wall-clock *and* peak RSS — persistent maps often lose on RSS due to node overhead even when they win on clone-time.\\n\\n### 3. Parser\\n\\nHand-roll is the right call given the explicit goal is *golden-parity of error messages*, not just successful parses. `chumsky`/`winnow` optimize for combinator ergonomics and give you decent error recovery for free, but matching Python's specific error message wording/positions exactly through a combinator library's error model is friction you don't need in a differential-oracle context — you'd fight the library to reproduce quirks rather than benefiting from it. Once golden-parity is achieved and frozen (i.e., you have a byte-for-byte diffable error corpus), you can *then* evaluate whether a combinator rewrite still holds parity — but do that as a later refactor gated by the same oracle, not up front.\\n\\n### 4. The oracle\\n\\nThis is where I'd push hardest. `scripts/oracle_compare.py` is a great reference but it's built for a different job: cross-tool fuzzy matching against *external* tools with different line-numbering conventions (`near()` at Line 204: `a.fkey == b.fkey and abs(a.line - b.line) <= tol`, default tolerance 3 lines) and coarse severity buckets (`leak`/`use-after`/`double`/`other`). For a **golden** Python-vs-Rust comparison where both consume the identical source and OwnIR, you want the strict mode: exact `(path, line, code, subject)` set equality, not line-window fuzzy matching — reusing `near()` as-is would silently mask real divergences (e.g., an off-by-one in the Rust CFG lowering would slip through a ±3-line tolerance).\\n\\nBlind spots the SARIF/JSON contract comparison structurally can't catch:\\n- **Crashes/panics on valid input** — a Rust panic has no SARIF representation; the oracle needs an explicit \\\"did both binaries exit 0\\\" gate before it even diffs output.\\n- **Determinism/ordering** within the same `(line, code)` — if two diagnostics tie on the sort key, is intra-tie order also pinned, or could it drift silently?\\n- **Evidence step *semantics*, not just SARIF shape** — the `role` field (`\\\"moved\\\"`, `\\\"acquired\\\"` in `analysis.py`) drives label text; verify the oracle diffs message text too, not just `codeFlows` locations, since a step landing on the right line with the wrong label is a semantic bug SARIF-location-diffing alone won't catch.\\n- **Performance/timeout divergence** and **stderr/warning output** (e.g., P-014's OWN050 advisory) — neither is in SARIF and both matter for parity claims.\\n- **`.ownreport.json` fields not modeled in SARIF** — the doc says these contracts are compared \\\"layer by layer\\\" (Line 201), which is right; just don't let \\\"SARIF-clean\\\" imply \\\"fully parity\\\" in the CI gate's messaging.\\n\\n### 5. Prior art\\n\\nYour list is strong. One I'd add: **`clippy`'s lint-pass registry** (distinct from rustc's own dataflow) is a closer analogue to your OWN-code registry than `ruff`'s in some ways, since it's a second-party lint layer bolted onto a compiler's MIR, similar to how your analyses sit atop OwnIR facts from external frontends. Also worth a look: **`prusti-viper`**'s encoding boundary (Rust MIR → Viper IR) as a model for how you'd eventually seam a verification backend (ties back to P-002) onto `own-ir` without touching `own-analysis`.\\n\\n### 6. Repo layout\\n\\nMonorepo is right for this phase — the oracle's whole value proposition is \\\"one clone, one CI run, diff both binaries,\\\" and a sibling repo adds submodule/pinned-SHA ceremony that only pays off once the Rust core is independently versioned/released. Revisit the split once Rust is authoritative and Python becomes the legacy/reference-only artifact — at that point the coupling direction inverts and a monorepo's blast radius (Rust CI running on every Python-only doc change, etc.) becomes the annoyance instead of the benefit.\\n\\n

If the Rust port reuses it here, changes in evidence/codeFlows, subject/resource metadata, warning/advisory levels, non-leak diagnostics, full paths, ordering, or even exit status can still pass as “parity”.

If the Rust port starts diffing CFGs as written, there is no Python JSON oracle to compare against, and mirroring the text dump would bake in a non-contract debug format.

\",\"path\":null,\"side\":null,\"line\":null}{\"type\":\"pull_request_comment\",\"body\":\"Thanks both — genuinely useful architecture pushback. Folded all of it into `e2e0721`. Two points converged across both reviewers; one was Codex-only. Summary of what changed in P-022:\\n\\n**Codegen ⊥ diagnostics** (Codex P2 @65 + CodeRabbit #1) — redrew the DAG: `own-codegen` and `own-diagnostics` are now **sibling consumers** of `own-cfg`/`own-analysis`, not chained. Documented that codegen is verdict-independent (AST/CFG-driven, matching Python `codegen.generate(mod)`), and added a fitness function locking `own-codegen !→ own-diagnostics` (and `!→ own-analysis` for now; a future edge is an explicit, reviewed change to the allowed set).\\n\\n**Oracle is not `oracle_compare.py`** (Codex **P1** @191 + CodeRabbit #4) — you're right that it's a cross-tool *fuzzy* matcher (leak-only, ±N-line `near()`, coarse severity) and would mask off-by-one / label / subject / exit-status divergences. The doc now specs a **new exact harness** over canonicalized `status + stdout + stderr + SARIF/JSON`: exit/crash gate first, strict set-equality on `(path, line, code, subject)` **plus evidence label text**, pinned intra-tie ordering, and \\\"SARIF-clean ≠ full parity\\\". `oracle_compare.py` is referenced only for SARIF-reading plumbing.\\n\\n**CFG-JSON seam doesn't exist yet** (Codex P2 @185) — correct, `cfg` prints human text via `_print_cfg`, no `--format json`. Added migration **step 0**: build + freeze a canonical `cfg --format json` on the Python side before the ratchet leans on that seam; don't bake the debug dump in as a contract.\\n\\n**Also folded (CodeRabbit):** arena+CoW as the likely winner for this procedural workload (bench largest *real* function, wall-clock **and** RSS); prior art += clippy lint-pass registry + prusti-viper encoding boundary; parser combinator-rewrite deferred behind frozen error-parity; monorepo revisit-trigger noted.\\n\\nStill a draft / design doc — no code yet.

Do not add runtime “released?” flags to paper over static mistakes.\n- OwnIR schema is versioned in `ownlang/ownir.py`; additive optional fields like resource/type metadata are tolerated, incompatible vocabulary changes must fail loudly.\n- For C# repo scans, `scripts/own-check.sh` is the Action/bash surface and defaults to `--flow-locals`; on Windows use `scripts\\own-check.ps1` rather than requiring bash.\n- The Roslyn extractor auto-adds built `bin/` refs for `.csproj`/`.sln` inputs unless `--no-project-refs`; unresolved external events become advisory OWN050, not guessed leaks.\n- `audit/` must stay decoupled from `ownlang` and consumes `own-check` only through its CLI/SARIF; `audit/README.md` says active audit development currently lives in the separate OwnAudit repo.\n- Existing Cursor guidance: if CodeGraph MCP tools are available, prefer them for structural symbol/caller/impact questions; use text search for literal strings and comments.\n\n",{"_408":683,"_389":390,"_410":396},{"_411":684,"_413":-5,"_42":-5,"_414":-5,"_415":-5,"_97":685,"_93":417},[686,687],"developer",{"_46":689,"_93":674},{"_46":688,"_93":674},"\n## Skills\nA skill is a set of local instructions to follow that is stored in a `SKILL.md` file. Below is the list of skills that can be used. Each entry includes a name, description, and file path so you can open the source for full instructions when using a specific skill.\n### Available skills\n- imagegen: Generate or edit raster images when the task benefits from AI-created bitmap visuals such as photos, illustrations, textures, sprites, mockups, or transparent-background cutouts. Use when Codex should create a brand-new image, transform an existing image, or derive visual variants from references, and the output should be a bitmap asset rather than repo-native code or vector. Do not use when the task is better handled by editing existing SVG/vector/code-native assets, extending an established icon or logo system, or building the visual directly in HTML/CSS/canvas. (file: /opt/codex/skills/.system/imagegen/SKILL.md)\n- openai-docs: Use when the user asks how to build with OpenAI products or APIs and needs up-to-date official documentation with citations, help choosing the latest model for a use case, or model upgrade and prompt-upgrade guidance; prioritize OpenAI docs MCP tools, use bundled references only as helper context, and restrict any fallback browsing to official OpenAI domains. (file: /opt/codex/skills/.system/openai-docs/SKILL.md)\n- plugin-creator: Create and scaffold plugin directories for Codex with a required `.codex-plugin/plugin.json`, optional plugin folders/files, and baseline placeholders you can edit before publishing or testing. Use when Codex needs to create a new local plugin, add optional plugin structure, or generate or update repo-root `.agents/plugins/marketplace.json` entries for plugin ordering and availability metadata. (file: /opt/codex/skills/.system/plugin-creator/SKILL.md)\n- skill-creator: Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Codex's capabilities with specialized knowledge, workflows, or tool integrations. (file: /opt/codex/skills/.system/skill-creator/SKILL.md)\n- skill-installer: Install Codex skills into $CODEX_HOME/skills from a curated list or a GitHub repo path. Use when a user asks to list installable skills, install a curated skill, or install a skill from another repo (including private repos). (file: /opt/codex/skills/.system/skill-installer/SKILL.md)\n### How to use skills\n- Discovery: The list above is the skills available in this session (name + description + file path). Skill bodies live on disk at the listed paths.\n- Trigger rules: If the user names a skill (with `$SkillName` or plain text) OR the task clearly matches a skill's description shown above, you must use that skill for that turn. Multiple mentions mean use them all. Do not carry skills across turns unless re-mentioned.\n- Missing/blocked: If a named skill isn't in the list or the path can't be read, say so briefly and continue with the best fallback.\n- How to use a skill (progressive disclosure):\n 1) After deciding to use a skill, open its `SKILL.md`. Read only enough to follow the workflow.\n 2) When `SKILL.md` references relative paths (e.g., `scripts/foo.py`), resolve them relative to the skill directory listed above first, and only consider other paths if needed.\n 3) If `SKILL.md` points to extra folders such as `references/`, load only the specific files needed for the request; don't bulk-load everything.\n 4) If `scripts/` exist, prefer running or patching them instead of retyping large code blocks.\n 5) If `assets/` or templates exist, reuse them instead of recreating from scratch.\n- Coordination and sequencing:\n - If multiple skills apply, choose the minimal set that covers the request and state the order you'll use them.\n - Announce which skill(s) you're using and why (one short line). If you skip an obvious skill, say why.\n- Context hygiene:\n - Keep context small: summarize long sections instead of pasting them; only load extra files when needed.\n - Avoid deep reference-chasing: prefer opening only files directly linked from `SKILL.md` unless you're blocked.\n - When variants exist (frameworks, providers, domains), pick only the relevant reference file(s) and note that choice.\n- Safety and fallback: If a skill can't be applied cleanly (missing files, unclear instructions), state the issue, pick the next-best approach, and continue.\n","\nFilesystem sandboxing defines which files can be read or written. `sandbox_mode` is `danger-full-access`: No filesystem sandboxing - all commands are permitted. Network access is enabled.\nApproval policy is currently never. Do not provide the `sandbox_permissions` for any reason, commands will be rejected.\n","turn/started",{"_389":390,"_88":692},{"_104":-5,"_42":396,"_397":693,"_399":400,"_401":694},[],"inProgress",{"_401":696,"_389":390},{"_697":698,"_93":699},"activeFlags",[],"active","thread/started",{"_702":703},"thread",{"_704":-5,"_705":-5,"_706":707,"_708":400,"_473":474,"_709":15,"_710":-5,"_711":-5,"_712":-5,"_713":714,"_42":390,"_715":716,"_182":-5,"_717":-5,"_162":718,"_719":200,"_720":-5,"_478":721,"_401":722,"_723":-5,"_78":724,"_725":400},"agentNickname","agentRole","cliVersion","0.128.0","createdAt","ephemeral","extra","forkedFromId","gitInfo","historyMode","legacy","modelProvider","openai","parentThreadId","/opt/codex/sessions/2026/07/03/rollout-2026-07-03T02-52-20-019f25e4-3439-7f60-a38d-6482a11004b5.jsonl","preview","recencyAt","vscode",{"_93":405},"threadSource",[],"updatedAt",[],"messages",[729],{"_42":730,"_731":732,"_733":734,"_735":734,"_411":736,"_401":737,"_413":-5,"_738":32,"_739":740,"_741":742,"_743":-5},"a38516a9-c6fb-4581-8c23-10633689c34c","author",{"_97":325,"_182":-5,"_739":752},"create_time",1783047139.653588,"update_time",{"_748":46,"_749":750},"finished_successfully","weight","metadata",{"_744":745},"recipient","all","channel","l1239dk1",{"_746":747},"inline_comments",[],"content_type","parts",[751],"Thanks @codex — all four folded into `b23f5f8`:\n\n- **OWN050 is SARIF, not stderr** (@325) — corrected.

\n\n\n_{Comment `@coderabbitai help` to get the list of available commands.}\n\n\n@coderabbitai review\n@codex review\n\nThis is an **architecture brainstorm**, not a gate — `docs/proposals/P-022-rust-core-migration.md` is a design-only, bird's-eye plan for porting the Python core to Rust with the Python repo as a differential oracle. Please push back hard on the architecture, not the prose. Prompts I'd love takes on:\n\n1. **Crate DAG / coupling.** Is `own-syntax → own-cfg → own-analysis → own-diagnostics → own-codegen → own-cli` (with `own-ir` as a leaf-ish contract) the right decomposition? Where would coupling realistically leak — e.g. does `own-diagnostics` end up needing analysis internals for evidence, breaking the \"verdict layer independent of the solver\" invariant?\n2. **Dataflow state representation.** Persistent maps (`imbl`/`rpds`) vs an arena + copy-on-write for `State` at merges — which wins for a monotone worklist over a finite lattice, and what should we actually benchmark?\n3. **Parser.** Hand-rolled recursive descent (for golden-parity of error messages) vs `chumsky`/`winnow`. Trade-offs for a differential-oracle context?\n4. **The oracle itself.** Comparing on the SARIF/JSON contract via the existing `scripts/oracle_compare.py` (the Rust core as \"just another SARIF producer\") — what are the blind spots? Which divergences would this miss (e.g. things not represented in SARIF), and how would you close them?\n5. **Prior art.** Anything better than ruff / rust-analyzer / `rustc_mir_dataflow` / Polonius to steal the analysis-pass + lattice + registry architecture from?\n6. **Repo layout.** Monorepo (`rust/` subtree, easiest for the oracle to run both) vs sibling repo — any reason to prefer the split?\n\nFindings/suggestions welcome as inline comments on the doc. Thanks!\n\n---\n_Generated by [Claude Code](https://claude.ai/code)_\n\n\n

\n\n`@PhysShell` Read the doc end to end plus cross-checked the claims against `ownlang/analysis.py`, `ownlang/diagnostics.py`, `ownlang/evidence.py`, and `ownlang/codegen.py`. This is a genuinely well-argued bird's-eye plan — the strongest part is that the oracle rides on contracts you already froze (SARIF/evidence) rather than internal state. Pushback per prompt:\n\n### 1. Crate DAG / coupling\n\nThe `own-analysis → own-diagnostics` edge is actually *validated* by the current code: `ownlang/analysis.py` (Lines 239–262, 605–673) constructs `Evidence` — a type owned by `ownlang/diagnostics.py` — using solver-internal state (`st`, `rid`, line lookups). So the dependency correctly points from the solver toward the verdict/data type, not the reverse. Good sign the invariant will hold in Rust too (own-analysis depends on the `Evidence`/`Diagnostic` structs from own-diagnostics; own-diagnostics never reaches back into `Lattice`/worklist internals).\n\nBut I think the diagram has one edge that doesn't match reality: **`own-diagnostics ──▶ own-codegen`**. In the Python core, `codegen.generate(mod: A.Module)` (`ownlang/codegen.py:792`) takes only the AST — it never imports `diagnostics.py` or consumes `Diagnostic`/`Evidence`. Codegen is decided purely from AST-level shape (`_fn_has_buffer`, `_laminar_scopes`, `_buffer_modes`, etc.), not from analysis verdicts. If that stays true in Rust, `own-codegen` should depend on `own-cfg`/AST types directly, and the \"verdict-independent codegen\" fact is worth stating explicitly rather than implied by a diagram edge that suggests codegen is downstream of diagnostics. If Rust codegen *does* eventually want ownership verdicts (e.g., inserting a generated `Dispose()` based on the solver's own conclusions rather than re-deriving policy from AST shape), that's a deliberate new coupling worth flagging separately — don't let it sneak in through the diagnostics layer just because the arrow already points that way in the doc.\n\n### 2. Dataflow state representation\n\nAgree persistent maps are the right *default* to reach for, but bench against arena+generational-index CoW before committing, because:\n- `imbl`/`rpds` win when merges are frequent and sharing is high (wide CFGs, many join points) — structural sharing amortizes well.\n- A dense arena with a \"dirty\" bitset + copy-on-write clone wins when the analysis is mostly linear (few merges) and state is small per-RID, since persistent-map lookup has a real per-access constant-factor cost that a flat `Vec` doesn't.\n- Given the doc's own description of the analyses (ownership/lifetime/effect/DI) as fairly *procedural* with modest branching per function (not the wide, deeply-nested CFGs of a whole-program solver), I'd bet the arena+CoW wins on this workload, and `imbl` wins only if you graduate to interprocedural/whole-program dataflow later. Benchmark on the corpus's largest real function (not synthetic), and measure both wall-clock *and* peak RSS — persistent maps often lose on RSS due to node overhead even when they win on clone-time.\n\n### 3. Parser\n\nHand-roll is the right call given the explicit goal is *golden-parity of error messages*, not just successful parses. `chumsky`/`winnow` optimize for combinator ergonomics and give you decent error recovery for free, but matching Python's specific error message wording/positions exactly through a combinator library's error model is friction you don't need in a differential-oracle context — you'd fight the library to reproduce quirks rather than benefiting from it. Once golden-parity is achieved and frozen (i.e., you have a byte-for-byte diffable error corpus), you can *then* evaluate whether a combinator rewrite still holds parity — but do that as a later refactor gated by the same oracle, not up front.\n\n### 4. The oracle\n\nThis is where I'd push hardest. `scripts/oracle_compare.py` is a great reference but it's built for a different job: cross-tool fuzzy matching against *external* tools with different line-numbering conventions (`near()` at Line 204: `a.fkey == b.fkey and abs(a.line - b.line) <= tol`, default tolerance 3 lines) and coarse severity buckets (`leak`/`use-after`/`double`/`other`). For a **golden** Python-vs-Rust comparison where both consume the identical source and OwnIR, you want the strict mode: exact `(path, line, code, subject)` set equality, not line-window fuzzy matching — reusing `near()` as-is would silently mask real divergences (e.g., an off-by-one in the Rust CFG lowering would slip through a ±3-line tolerance).\n\nBlind spots the SARIF/JSON contract comparison structurally can't catch:\n- **Crashes/panics on valid input** — a Rust panic has no SARIF representation; the oracle needs an explicit \"did both binaries exit 0\" gate before it even diffs output.\n- **Determinism/ordering** within the same `(line, code)` — if two diagnostics tie on the sort key, is intra-tie order also pinned, or could it drift silently?\n- **Evidence step *semantics*, not just SARIF shape** — the `role` field (`\"moved\"`, `\"acquired\"` in `analysis.py`) drives label text; verify the oracle diffs message text too, not just `codeFlows` locations, since a step landing on the right line with the wrong label is a semantic bug SARIF-location-diffing alone won't catch.\n- **Performance/timeout divergence** and **stderr/warning output** (e.g., P-014's OWN050 advisory) — neither is in SARIF and both matter for parity claims.\n- **`.ownreport.json` fields not modeled in SARIF** — the doc says these contracts are compared \"layer by layer\" (Line 201), which is right; just don't let \"SARIF-clean\" imply \"fully parity\" in the CI gate's messaging.\n\n### 5. Prior art\n\nYour list is strong. One I'd add: **`clippy`'s lint-pass registry** (distinct from rustc's own dataflow) is a closer analogue to your OWN-code registry than `ruff`'s in some ways, since it's a second-party lint layer bolted onto a compiler's MIR, similar to how your analyses sit atop OwnIR facts from external frontends. Also worth a look: **`prusti-viper`**'s encoding boundary (Rust MIR → Viper IR) as a model for how you'd eventually seam a verification backend (ties back to P-002) onto `own-ir` without touching `own-analysis`.\n\n### 6. Repo layout\n\nMonorepo is right for this phase — the oracle's whole value proposition is \"one clone, one CI run, diff both binaries,\" and a sibling repo adds submodule/pinned-SHA ceremony that only pays off once the Rust core is independently versioned/released. Revisit the split once Rust is authoritative and Python becomes the legacy/reference-only artifact — at that point the coupling direction inverts and a monorepo's blast radius (Rust CI running on every Python-only doc change, etc.) becomes the annoyance instead of the benefit.\n\n

\n**_{_{![P1 Badge](https://img.shields.io/badge/P1-orange?style=flat)}} Replace the cross-tool oracle before using it for parity**\n\n`scripts/oracle_compare.py` is not an exact implementation-parity oracle: it parses SARIF down to `(path, line, rule, message, cls)`, then `compare()` keeps only leak-class findings and matches by basename within a line tolerance. If the Rust port reuses it here, changes in evidence/codeFlows, subject/resource metadata, warning/advisory levels, non-leak diagnostics, full paths, ordering, or even exit status can still pass as “parity”. For the Rust migration, make this a new exact diff harness over canonical stdout/stderr/status/SARIF, or extend the script with an exact mode, instead of using the cross-tool oracle.\n\nUseful? React with 👍 / 👎.\n**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Route codegen around diagnostics**\n\nThe diagram locks `own-codegen` behind `own-diagnostics`, but the crate notes say codegen emits from CFG + analysis results. With the allowed-edge test proposed below, codegen would have no legal access to solver result types unless `own-diagnostics` re-exports analysis internals or codegen re-runs/duplicates analysis, which breaks the stated “diagnostics knows nothing about solver internals” invariant. Model diagnostics and codegen as sibling consumers of `own-cfg`/`own-analysis` instead of chaining codegen through the verdict renderer.\n\nUseful? React with 👍 / 👎.\n**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Add a canonical CFG JSON seam before depending on it**\n\nThis treats `cfg` JSON as an existing per-layer contract, but the Python CLI currently prints a human CFG with `_print_cfg` and has no `--format json` surface. If the Rust port starts diffing CFGs as written, there is no Python JSON oracle to compare against, and mirroring the text dump would bake in a non-contract debug format. Add and freeze a canonical Python CFG JSON export before the ratchet uses this seam.\n\nUseful?

\nThanks both — genuinely useful architecture pushback. Folded all of it into `e2e0721`. Two points converged across both reviewers; one was Codex-only. Summary of what changed in P-022:\n\n**Codegen ⊥ diagnostics** (Codex P2 @65 + CodeRabbit #1) — redrew the DAG: `own-codegen` and `own-diagnostics` are now **sibling consumers** of `own-cfg`/`own-analysis`, not chained. Documented that codegen is verdict-independent (AST/CFG-driven, matching Python `codegen.generate(mod)`), and added a fitness function locking `own-codegen !→ own-diagnostics` (and `!→ own-analysis` for now; a future edge is an explicit, reviewed change to the allowed set).\n\n**Oracle is not `oracle_compare.py`** (Codex **P1** @191 + CodeRabbit #4) — you're right that it's a cross-tool *fuzzy* matcher (leak-only, ±N-line `near()`, coarse severity) and would mask off-by-one / label / subject / exit-status divergences. The doc now specs a **new exact harness** over canonicalized `status + stdout + stderr + SARIF/JSON`: exit/crash gate first, strict set-equality on `(path, line, code, subject)` **plus evidence label text**, pinned intra-tie ordering, and \"SARIF-clean ≠ full parity\". `oracle_compare.py` is referenced only for SARIF-reading plumbing.\n\n**CFG-JSON seam doesn't exist yet** (Codex P2 @185) — correct, `cfg` prints human text via `_print_cfg`, no `--format json`. Added migration **step 0**: build + freeze a canonical `cfg --format json` on the Python side before the ratchet leans on that seam; don't bake the debug dump in as a contract.\n\n**Also folded (CodeRabbit):** arena+CoW as the likely winner for this procedural workload (bench largest *real* function, wall-clock **and** RSS); prior art += clippy lint-pass registry + prusti-viper encoding boundary; parser combinator-rewrite deferred behind frozen error-parity; monorepo revisit-trigger noted.\n\nStill a draft / design doc — no code yet. Further pushback welcome.\n\n---\n_Generated by [Claude Code](https://claude.ai/code)_\n@codex review\n\nSpecifically: please pressure-test and **extend the \"Performance principles\" section** of `docs/proposals/P-022-rust-core-migration.md` with your own suggestions for this workload (a static-analyzer / compiler frontend — parse → CFG → monotone worklist dataflow → diagnostics/SARIF, ported from the Python `ownlang/` core, with a differential oracle vs Python as the correctness gate).\n\nAlready covered (please add **net-new**, not repeats):\n- intern everything (u32 symbols), FxHashMap for small-int keys\n- bitset lattice (`u8` bitflags for `VarState` + dense `Vec<_>` by RID) instead of `HashSet`\n- bump/typed arena for the immutable AST/CFG + `u32` indices; flat backing arrays over `Vec>`\n- `SmallVec` for the many-small collections (evidence steps, loans, per-block diags)\n- enums / `impl Trait` / `&dyn` over `Box`\n- `rayon` across independent per-function analyses; `mimalloc`/`jemalloc`\n- discipline: profile by cumulative cost, keep the transfer function pure, `#[inline]` only tiny cross-crate hot fns, LTO + `panic=abort`, micro-opt last\n- perf locked by an `iai-callgrind` instruction-count ratchet in CI\n\nWhat am I missing? Candidates I'd love your take on: worklist scheduling / RPO ordering to cut fixpoint iterations; representing the worklist itself (bitset-of-blocks vs `VecDeque` + in-queue flag); avoiding re-allocation across the per-block transfer (scratch buffers / state pooling); whether persistent maps (`imbl`) ever beat arena+CoW for our merge frequency; `serde`/SARIF serialization cost on large OwnIR inputs; string handling in diagnostics rendering; and anything about incremental/`salsa` that changes the data-model choices now. Concrete crate/pattern picks welcome.\n\n---\n_Generated by [Claude Code](https://claude.ai/code)_\n**_{_{![P3 Badge](https://img.shields.io/badge/P3-lightgrey?style=flat)}} Keep OwnIR and SARIF I/O in the perf budget**\n\nFor CLI/CI scans over large OwnIR dumps, `serde_json` parsing and SARIF/report rendering happen on every input and are O(input + findings), so after the transfer loop is optimized they can dominate wall time and allocations. This sentence tells implementers to exclude that path from profiling; add representative large OwnIR/SARIF benches (e.g. `from_slice`/`to_writer` with buffered output and borrowed/interned diagnostic strings) rather than only transfer-function microbenches.\n\nUseful? React with 👍 / 👎.\n**_{_{![P3 Badge](https://img.shields.io/badge/P3-lightgrey?style=flat)}} Avoid baking in persistent maps as the default state**\n\nThis table presents `imbl`/`rpds` as the replacement for `State.copy()`, but the same proposal later argues dense bitset/`Vec` arena+CoW is likely better for this workload. If this row is followed during the port, the solver may get locked into tree-node allocation and O(log n) lookups before the corpus benchmark has compared it with state pooling/scratch-buffer CoW, so make persistent maps an explicit benchmark candidate rather than the default idiom.\n\nUseful? React with 👍 / 👎.\n**_{_{![P3 Badge](https://img.shields.io/badge/P3-lightgrey?style=flat)}} Specify RPO-guided worklist scheduling**\n\nThe solver shape is left as a generic forward worklist, but for monotone intraprocedural analyses with loops, block order determines how many times joins and transfers rerun. Without an RPO/postorder scheduling principle plus a cheap `in_queue` bitset (or dense bitset-of-blocks for small CFGs), an implementation can burn most of its time revisiting blocks and reallocating states even with the compact lattice described below.\n\nUseful? React with 👍 / 👎.\n**_{_{![P3 Badge](https://img.shields.io/badge/P3-lightgrey?style=flat)}} Don't treat OWN050 as stderr-only**\n\nCurrent `ownir` SARIF output passes the shown findings into `build_sarif` (`ownlang/__main__.py:320-325`), and the test suite pins advisory OWN050 as a SARIF result with `level: \"note\"` (`tests/test_ownir.py:2251-2263`). Saying these notes live in stderr can make the exact oracle compare the wrong stream or double-count human summary text; stderr is only the machine-format summary/chatter, while the advisory finding remains semantic SARIF output.\n\nUseful?

This sentence tells implementers to exclude that path from profiling; add representative large OwnIR/SARIF benches (e.g. `from_slice`/`to_writer` with buffered output and borrowed/interned diagnostic strings) rather than only transfer-function microbenches.\n\nUseful?

Candidates I'd love your take on: worklist scheduling / RPO ordering to cut fixpoint iterations; representing the worklist itself (bitset-of-blocks vs `VecDeque` + in-queue flag); avoiding re-allocation across the per-block transfer (scratch buffers / state pooling); whether persistent maps (`imbl`) ever beat arena+CoW for our merge frequency; `serde`/SARIF serialization cost on large OwnIR inputs; string handling in diagnostics rendering; and anything about incremental/`salsa` that changes the data-model choices now. Concrete crate/pattern picks welcome.\n\n---\n_Generated by [Claude Code](https://claude.ai/code)_","Thanks both — genuinely useful architecture pushback. Folded all of it into `e2e0721`. Two points converged across both reviewers; one was Codex-only. Summary of what changed in P-022:\n\n**Codegen ⊥ diagnostics** (Codex P2 @65 + CodeRabbit #1) — redrew the DAG: `own-codegen` and `own-diagnostics` are now **sibling consumers** of `own-cfg`/`own-analysis`, not chained. Documented that codegen is verdict-independent (AST/CFG-driven, matching Python `codegen.generate(mod)`), and added a fitness function locking `own-codegen !→ own-diagnostics` (and `!→ own-analysis` for now; a future edge is an explicit, reviewed change to the allowed set).\n\n**Oracle is not `oracle_compare.py`** (Codex **P1** @191 + CodeRabbit #4) — you're right that it's a cross-tool *fuzzy* matcher (leak-only, ±N-line `near()`, coarse severity) and would mask off-by-one / label / subject / exit-status divergences. The doc now specs a **new exact harness** over canonicalized `status + stdout + stderr + SARIF/JSON`: exit/crash gate first, strict set-equality on `(path, line, code, subject)` **plus evidence label text**, pinned intra-tie ordering, and \"SARIF-clean ≠ full parity\". `oracle_compare.py` is referenced only for SARIF-reading plumbing.\n\n**CFG-JSON seam doesn't exist yet** (Codex P2 @185) — correct, `cfg` prints human text via `_print_cfg`, no `--format json`. Added migration **step 0**: build + freeze a canonical `cfg --format json` on the Python side before the ratchet leans on that seam; don't bake the debug dump in as a contract.\n\n**Also folded (CodeRabbit):** arena+CoW as the likely winner for this procedural workload (bench largest *real* function, wall-clock **and** RSS); prior art += clippy lint-pass registry + prusti-viper encoding boundary; parser combinator-rewrite deferred behind frozen error-parity; monorepo revisit-trigger noted.\n\nStill a draft / design doc — no code yet.

","**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Add a canonical CFG JSON seam before depending on it**\n\nThis treats `cfg` JSON as an existing per-layer contract, but the Python CLI currently prints a human CFG with `_print_cfg` and has no `--format json` surface. If the Rust port starts diffing CFGs as written, there is no Python JSON oracle to compare against, and mirroring the text dump would bake in a non-contract debug format. Add and freeze a canonical Python CFG JSON export before the ratchet uses this seam.\n\nUseful? React with 👍 / 👎.","**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Route codegen around diagnostics**\n\nThe diagram locks `own-codegen` behind `own-diagnostics`, but the crate notes say codegen emits from CFG + analysis results. With the allowed-edge test proposed below, codegen would have no legal access to solver result types unless `own-diagnostics` re-exports analysis internals or codegen re-runs/duplicates analysis, which breaks the stated “diagnostics knows nothing about solver internals” invariant. Model diagnostics and codegen as sibling consumers of `own-cfg`/`own-analysis` instead of chaining codegen through the verdict renderer.\n\nUseful? React with 👍 / 👎.","**_{_{![P1 Badge](https://img.shields.io/badge/P1-orange?style=flat)}} Replace the cross-tool oracle before using it for parity**\n\n`scripts/oracle_compare.py` is not an exact implementation-parity oracle: it parses SARIF down to `(path, line, rule, message, cls)`, then `compare()` keeps only leak-class findings and matches by basename within a line tolerance. If the Rust port reuses it here, changes in evidence/codeFlows, subject/resource metadata, warning/advisory levels, non-leak diagnostics, full paths, ordering, or even exit status can still pass as “parity”. For the Rust migration, make this a new exact diff harness over canonical stdout/stderr/status/SARIF, or extend the script with an exact mode, instead of using the cross-tool oracle.\n\nUseful?

","@coderabbitai review\n@codex review\n\nThis is an **architecture brainstorm**, not a gate — `docs/proposals/P-022-rust-core-migration.md` is a design-only, bird's-eye plan for porting the Python core to Rust with the Python repo as a differential oracle. Please push back hard on the architecture, not the prose. Prompts I'd love takes on:\n\n1. **Crate DAG / coupling.** Is `own-syntax → own-cfg → own-analysis → own-diagnostics → own-codegen → own-cli` (with `own-ir` as a leaf-ish contract) the right decomposition? Where would coupling realistically leak — e.g. does `own-diagnostics` end up needing analysis internals for evidence, breaking the \"verdict layer independent of the solver\" invariant?\n2. **Dataflow state representation.** Persistent maps (`imbl`/`rpds`) vs an arena + copy-on-write for `State` at merges — which wins for a monotone worklist over a finite lattice, and what should we actually benchmark?\n3. **Parser.** Hand-rolled recursive descent (for golden-parity of error messages) vs `chumsky`/`winnow`. Trade-offs for a differential-oracle context?\n4. **The oracle itself.** Comparing on the SARIF/JSON contract via the existing `scripts/oracle_compare.py` (the Rust core as \"just another SARIF producer\") — what are the blind spots? Which divergences would this miss (e.g. things not represented in SARIF), and how would you close them?\n5. **Prior art.** Anything better than ruff / rust-analyzer / `rustc_mir_dataflow` / Polonius to steal the analysis-pass + lattice + registry architecture from?\n6. **Repo layout.** Monorepo (`rust/` subtree, easiest for the oracle to run both) vs sibling repo — any reason to prefer the split?\n\nFindings/suggestions welcome as inline comments on the doc.

Кода на Rust пока нет — Python авторитетен, пока не сойдётся паритет. Документ отвечает на конкретные вопросы: крейт-топология (enforced acyclic DAG, decoupled по OwnIR-seam), Rust-идиомы против текущей accidental complexity, библиотеки-кандидаты, prior art, Rust architecture-fitness тулинг, и дизайн дифф-оракула поверх уже замороженных evidence/SARIF/JSON контрактов.\n\n**Это брейншторм-PR (draft): зову CodeRabbit и Codex специально ради архитектурного фидбека, а не как gate.** Особенно интересуют:\n- крейт-граница `own-analysis` vs `own-diagnostics`/`own-ir` — не течёт ли связность;\n- persistent state (`imbl`/`rpds`) vs arena+CoW для dataflow — что бенчить;\n- парсер: hand-roll vs `chumsky`/`winnow` для golden-parity;\n- дифф-оракул: сравнение по SARIF-контракту через существующий `scripts/oracle_compare.py` — дыры в подходе?\n- monorepo (`rust/` subtree) vs sibling-repo.\n\n## Тип изменения\n- [x] docs — документация\n- [ ] feat / fix / refactor / chore / test / ci\n\n## Как проверено\n- [x] docs-only; кода нет. Проверять нечего — Python-ядро и гейт не затронуты.\n- [ ] `python tests/run_tests.py`\n- [ ] `ruff check .` и `mypy`\n\n## Связанные issue\nНет связанного issue. Follow-up к execution-surfaces ADR (#164, #165) — Rust-переезд как триггер из §8.\n\n## Чеклист\n- [x] изменение покрыто тестом/селфтестом (или объяснено, почему нет) — docs-only, тестировать нечего\n- [x] README/docs обновлены — добавлен P-022, обновлён индекс `docs/proposals/README.md`\n- [x] коммиты в conventional-commit стиле (`docs:`)\n\n🤖 Generated with [Claude Code](https://claude.com/claude-code)\n\n---\n_Generated by [Claude Code](https://claude.ai/code/session_01TSqD7TSzxAnGWszaFwTZVt)_","base_ref","head_ref","pull_request_info",[1247],{"_748":46,"_46":1248},"Thanks @codex — all four folded into `b23f5f8`:\n\n- **OWN050 is SARIF, not stderr** (@325) — corrected. You're right: it's a real result at `level: \"note\"` (pinned in `test_ownir.py`), so the exact oracle compares it on the SARIF seam; stderr is only the machine-format summary/chatter. Fixed the exit/crash-gate bullet so we don't diff the wrong stream or double-count.\n- **RPO worklist scheduling** (@123) — added as a first-class lever: reverse-postorder visitation to minimize fixpoint iterations, an `in_queue` bitset (dense bitset-of-blocks for small CFGs) to avoid double-enqueue, and scratch-state reuse across transfers. Good catch that the compact lattice alone doesn't buy this.\n- **I/O in the perf budget** (@191) — softened \"one-time costs don't matter\": over large OwnIR dumps `serde_json` parse + SARIF render are O(input+findings) per run and can dominate once the transfer is tight, so the perf section now calls for representative large-OwnIR `from_slice` / buffered `to_writer` benches with interned strings, not only transfer microbenches.\n- **Persistent maps ≠ default** (@116) — the state row now reads \"dense bitset `Vec` + arena/scratch CoW (leaning default); `imbl`/`rpds` (benchmark
