+# TRANCHE: THE FULL DICHOTOMY REBASE v2 — every Python module replaced, zero Python runtime
+
+_Revised per Nick's corrections: Bubble Tea for the TUI, henxels scope first, HOW instructions per step, Gitea epic + MiMoCode tasks, timeline = 1 week. Presented for approval._
+
+---
+
+## §0 — GROUNDING (measured)
+
+| Language | Files | Lines | % | Status |
+|---|---|---|---|---|
+| Python | 180 | 68,224 | **70%** | **THE TARGET — every module ported** |
+| Rust | 106 | 27,304 | 28% | 10 crates, 85 more modules to port |
+| Go | 7 | 1,125 | **1%** | 2 modules, 55 more to port |
+| **Total** | **293** | **96,653** | | |
+
+### The corrected dichotomy
+
+| Side | Modules | Python lines | Role |
+|---|---|---|---|
+| **GO** | 57 | 32,081 | Reactive shell: initiates, responds, routes, interfaces |
+| **RUST** | 85 | 25,218 | Deterministic backend: computes, stores, pure functions |
+| **TUI** | 7 | 5,435 | **Bubble Tea (Go)** — rewritten in Wave 7 |
+| **TEST** | 29 | 5,397 | Test infrastructure — stays Python (pytest) |
+
+### Keep-greens
+
+Full test suite (2,300+, 0 failures) · All 25 registered canaries · diff-cover ≥70% · Silent-handler ratchet (BLE001 ≤345, S110 ≤75) · Henxels all hold · Lint-baseline no increase · Deploy monotonic
+
+---
+
+## §1 — OBJECTIVE
+
+**Zero Python files in `src/rune/`.** Every module replaced by its Go or Rust equivalent. The TUI is rewritten in Bubble Tea (Go). Test infrastructure stays Python. The end state is a Go+Rust codebase with zero Python runtime dependency.
+
+Timeline: **1 week** (5 working days, aggressive but achievable with the wave structure below).
+
+---
+
+## §2 — WAVE 0: INFRASTRUCTURE FIRST (Day 1, morning)
+
+**This impacts everything else. Done before any porting.**
+
+### Step 1: Henxels scope extension
+- Add `src/rust/*/` scope to `henxels.yaml`: max_lines 3000 (Rust files are larger), no_secrets, filename_casing snake_case, canary registration
+- Add `src/go/**/` scope: max_lines 2000, no_secrets, filename_casing kebab-case
+- Add `new_rune_modules_have_canary_or_test_coverage` for both scopes
+- Verify: `henxels check --all` passes with the new scopes
+
+### Step 2: Umbrella manifest extension
+- Add 10 Rust crate entries to `config/umbrellas.json` (cognition_core, memory_retrieval, memory_storage, scaffold_core, evidence_provenance, rune_spine, memory_scoring, capability_scoring, token_counting, query_memory)
+- Add 2 Go module entries (event-bus, tool-executor) + placeholder entries for the 55 planned Go modules
+- Each entry: name, description, modules list, depends_on, canaries
+- Verify: `umbrella_manifest_is_complete` henxel passes
+
+### Step 3: Scaffolding protocol update
+- Update `construction_decision.py` GO_SIGNALS/RUST_SIGNALS to match the corrected dichotomy (57 GO / 85 RUST)
+- Update `store/rebase/classification.json` with the re-classified sides
+- Verify: `rune scaffold classify <test_objective>` routes to the correct language
+
+### Step 4: CI pipeline update
+- Add `cargo build --release --manifest-path src/rust/cognition_core/Cargo.toml` to the unit-tests and canary jobs
+- Add `CC_RUST_LIB` to the unit-tests job env
+- Add a `go-build` step that builds every Go module in `src/go/*/`
+- Add a `go-test` step that runs `go test ./...` in every Go module
+- Verify: CI pipeline passes with the new steps
+
+### Step 5: Gitea epic + MiMoCode tasks
+- Create the parent epic on Gitea: "Full Dichotomy Rebase — every Python module replaced" with the full wave structure as a folded checklist
+- Create per-wave sub-epics (W4-infra, W4b-tools, W5a-model, W5b-operator, W5c-memory, W6a/b/c-RUST, W7-TUI)
+- Mirror all of them in the MiMoCode task tool
+- Verify: the Gitea epic exists, the MiMoCode task tree matches

+### Wave 7: Bubble Tea TUI (Go) — Day 5
+
+| What | Python lines | Go target |
+|---|---|---|
+| rune_tui.py (the whole TUI) | 4,038 | `src/go/tui/` |
+
+**HOW:**
+1. Install Bubble Tea + Lipgloss + Bubbles: `go get github.com/charmbracelet/bubbletea github.com/charmbracelet/lipgloss github.com/charmbracelet/bubbles`
+2. Port the layout: `type Model struct { chatChan, taskChan ChannelView; workPane WorkPane; statusBar StatusBar }` — chat LEFT, task RIGHT
+3. Port the message rendering: chat bubbles with `lipgloss.Style{}.Foreground()`
+4. Port the command selector: Bubble Tea's `textinput` + `completions` component
+5. Port the keybindings: Ctrl+1 (chat), Ctrl+2 (task), Ctrl+3 (work pane)
+6. Port the status bar: version, mode, model, project, focused channel
+7. Port the post-response signal consolidation (one dim line)
+8. Wire the operator: the TUI calls the Go operator directly (same process) — no subprocess, no FFI, just function calls
+9. Animations: Bubble Tea supports animations via `tea.Tick` and `tea.Every` — spinners, progress bars, streaming text. Lipgloss supports colors, borders, padding. Pixel art is possible via block characters and custom rendering.
+10. Design: retain the current two-column layout (chat LEFT, task RIGHT) + work pane. Use Lipgloss for the same visual style. Port the chat bubble rendering, the thinking indicator, the tool call display.
+
+**Exit condition**: `go build ./src/go/tui/` produces a statically-linked binary that IS the Rune TUI. `find src/rune -name '*.py'` returns 0.

+## §4 — THE GITEA EPIC STRUCTURE
+
+The FIRST task posted to Gitea is the parent epic:
+
+**Epic #N: "Full Dichotomy Rebase — every Python module replaced"**
+
+Folded checklist inside the epic:
+- [ ] Wave 0: Infrastructure (henxels scope, umbrella manifest, scaffolding protocol, CI update)
+- [ ] Wave 4: Go reactive infrastructure (14 modules) — sub-epics per module
+- [ ] Wave 4b: Go tool execution (3 modules) — sub-epics per module
+- [ ] Wave 5a: Go model/provider (10 modules) — sub-epics per module
+- [ ] Wave 5b: Go operator (19 modules) — sub-epics per module
+- [ ] Wave 5c: Go memory operations (8 modules) — sub-epics per module
+- [ ] Wave 6a: Rust structural core (30 modules) — sub-epics per module
+- [ ] Wave 6b: Rust cognition (30 modules) — sub-epics per module
+- [ ] Wave 6c: Rust remaining (25 modules) — sub-epics per module
+- [ ] Wave 7: Bubble Tea TUI (7 modules) — sub-epics per module
+
+Each sub-epic contains the HOW instructions per the template in §3.
+
+MiMoCode task tool mirrors the same structure: T-tranche → T4-infra → T4.1-event-bus, T4.2-hook-engine, etc.
+
+---
+
+## §5 — BUBBLE TEA CAPABILITIES (answering Nick's question)
+
+**Animations**: Yes. Bubble Tea has `tea.Tick` (one-shot timer) and `tea.Every` (recurring). Spinners via the `bubbles/spinner` component. Progress bars via `bubbles/progress`. Streaming text via incremental updates.
+
+**Pixel art**: Possible via block characters (█ ▄ ▀ ▌ ▐) and custom renderers. Not true pixel-level control (it's a terminal), but with Unicode block elements and 256-color/truecolor support, you can get very close. Lipgloss supports borders, padding, alignment, colors, and gradients.
+
+**Presentable**: Yes. Bubble Tea + Lipgloss is what popular Go CLI tools use (gh, glow, soft-serve). It looks professional and modern.
+
+**Retaining the current design**: The two-column layout (chat LEFT, task RIGHT), the work pane, the status bar, the command selector, the chat bubbles — all of these map directly to Bubble Tea components. The visual style can be replicated with Lipgloss. The keybindings map directly.

+# Wave 1 / Memory & Persistence — Inward Intention Profile
+
+Checkout: `/mnt/workdrive/rune`. Scope: `src/rune/` memory subsystem. Method: static reading of the
+live implementation plus inspection of on-disk state under `~/.rune/`. No code changed.
+
+## On-disk state (measured)
+
+| Artifact | Size | Status |
+|---|---|---|
+| `~/.rune/hot/task_state.json` | 973 KB | live production, hot path |
+| `~/.rune/hot/conversation_messages.json` | 1.2 MB | live production, hot path |
+| `~/.rune/consolidation/knowledge.json` | 3.4 MB | live production, batch path |
+| `~/.rune/outcome_ledger.db` | 12 KB | SQLite, small |
+| `~/.rune/memory/store/memory.db` | — | defined by `memory_env.store_db()`, not yet materialized locally |
+
+## Cluster 1 — Hot-store JSON persistence
+
+- Intention: load/save mutable runtime state as JSON files (task state, conversation messages, knowledge).
+- Evidence: live files listed above; consolidation loads/saves `knowledge.json` in
+  `memory_consolidation.py:113-165` (JSON file load/save around the batch iterate/dedupe loop).
+- Compute profile: stdlib `json` encode/decode over 1–3.4 MB documents; CPU-bound but small in
+  absolute terms (tens of ms, not seconds). No incremental/append format, full rewrite per save.
+- Language fit: **Python already delegates this well** — see outward source 1 (orjson wheel) for the
+  upgrade path. A bespoke Rust CLI unit pays per-call subprocess spawn (contract: argv in / JSON out)
+  that likely exceeds the serialization time it saves.
+
+## Cluster 2 — SQLite store + FTS5/vec0 hybrid recall (`memory_store.py`)
+
+- Intention: dense + sparse retrieval fused by RRF, with query expansion, metadata rerank, QPP
+  abstention, drift rerank, map-reduce recall.
+- Evidence:
+  - `memory_store.py:575-897` — `recall()`: hybrid dense+BM25 fused by Reciprocal Rank Fusion.
+  - `memory_store.py:646` — dense KNN runs as SQLite virtual-table query: `SELECT ... FROM entries_vec v WHERE v.embedding MATCH ?` → **C inside SQLite** (sqlite-vec; outward source 3).
+  - `memory_store.py:693` — sparse half ranks with `bm25(entries_fts)` → **C inside SQLite** (FTS5; outward source 5).
+  - `memory_store.py:327-370` — `_embed()` shells out via subprocess `curl` to Ollama; network-bound, 60 s timeout. This, not Python, dominates recall latency.
+  - `memory_store.py:475` — `_df()` runs a per-word LIKE COUNT query (N+1 smell) but is bounded: `probe_cap ≈ 2 × budget` entries (≈ 40), so total SQL traffic is tiny.
+  - Python-side loops: RRF fusion over the small probe set, recency-decay/confidence/temperature multipliers, QPP abstention — per-item branching math over ≤ ~40 candidates.
+- Compute profile: the heavy kernels (KNN, BM25, ranking, tokenization) are already native C. Python is a thin orchestrator around them.
+- Language fit: a Go/Rust recode would replace thin Python glue around the same C extensions with
+  Go/Rust glue around the same C extensions, while losing ecosystem integration (`sqlite3`, orjson,
+  embedding plumbing). Outward sources 2, 3, 5 all point the same direction: keep SQLite, don't build custom storage/search.
+
+## Cluster 3 — Neuron scoring / routing (`warm_router.py`)
+
+- Intention: 7-signal heuristic scoring of memory "neurons" for routing: keyword substring match,
+  embedding cosine, context overlap, ACT-R base-level activation, wash boost (log1p), fan penalty,
+  trigger-length bonus.
+- Evidence: `warm_router.py:361-503` (`score_neuron`), `warm_router.py:504` (`route`).
+- Compute profile: the embedding cosine is computed via `memory_store._embed` (network HTTP to
+  Ollama, precomputed once per neuron set). The remaining signals are trivial string ops and scalar
+  arithmetic per neuron. Latency is dominated by the HTTP embed, not the scoring loop.
+- Language fit: branching heuristics over a small N with a network-bound dominate cost — no case for
+  Go/Rust/C.
+
+## Cluster 4 — Graph memory BFS (`graph_memory.py`)
+
+- Intention: entity/relation graph persisted in SQLite (`edges`, `entities` tables); query walks BFS
+  from seed entities up to `hops` (default 1); `graph_write` (:199) upserts.
+- Evidence: `graph_memory.py:261-343` (`query`), `graph_memory.py:199` (`graph_write`).
+- Compute profile: per-node SQL edge queries (N+1 pattern), but N is tiny (hops=1, few entities per
+  seed). The per-query cost is SQLite C; Python overhead is negligible.
+- Language fit: keep Python. If the graph ever scales, the fix is a recursive CTE in SQL — a
+  SQLite-level change, not a language change.
+
+## Cluster 5 — Batch consolidation / curator ops
+
+- Intention: off-hours batch jobs — knowledge consolidation, promote/decay/compress candidate
+  passes, LLM/heuristic judgment with worthiness filters and graded tiers; output as JSON block
+  files + journal.
+- Evidence: `memory_consolidation.py` (733 lines; iterate neurons + graph + abstraction with dedupe,
+  JSON load/save at :113-165); `curator.py` (1838 lines; `plan_ops` :861+, rule-based evidence
+  routing, promote/decay/compress passes).
+- Compute profile: I/O + LLM-call bound, latency-insensitive, batched. LLM calls dominate wall time.
+- Language fit: keep Python. Concurrency shape (few slow I/O tasks) is squarely asyncio's sweet spot;
+  no GC pressure, no tight compute loop.
+
+## Cluster 6 — Orchestration / glue (`sleep_time.py`, `night_mode.py`, `identity_anchors.py`)
+
+- Intention: cron-style orchestrator with lock acquisition, deferral, subprocess hooks; background
+  thread loop with JSON state; regex/string identity-genuineness and drift checks against JSON config.
+- Evidence: `sleep_time.py:586+` (orchestrator glue); `night_mode.py` (405 lines, thread loop +
+  JSON state); `identity_anchors.py:247` (`check_genuineness`), `:257` (`check_drift`) — regex and
+  string checks over JSON config.
+- Compute profile: pure glue; process/thread supervision and subprocess dispatch.
+- Language fit: keep Python. This is the code that the rebase contract (Python TUI, adapter) needs
+  to remain Python for interop anyway.
+
+## Cluster 7 — Embedding transport (`memory_store._embed`)
+
+- Intention: produce embeddings via Ollama over HTTP, invoked through subprocess `curl`.
+- Evidence: `memory_store.py:327-370` (subprocess curl, 60 s timeout); also used by
+  `warm_router.score_neuron` via precomputed embeds.
+- Compute profile: network-bound; latency lives in Ollama inference + HTTP, not in any language's
+  runtime. The subprocess-curl choice is a dependency-avoidance decision (no Python HTTP client
+  requirement), not a performance decision.
+- Language fit: keep Python at the call site. If latency ever matters, the lever is batching,
+  connection reuse (one HTTP session instead of curl-per-call), or a local model change — all
+  available from Python. A Rust/Go recode changes nothing that is slow.
+
+## Cross-cutting observations
+
+1. **The subsystem's heavy compute is already native.** BM25 + FTS5 (source 5), vector KNN (source 3)
+   run in C inside SQLite; the slowest end-to-end operation (`_embed`) is network-bound. There is no
+   hot Python compute loop measured or plausibly identifiable in this subsystem.
+2. **The adapter contract penalizes short-lived foreign units.** `shared/native_units.py` requires
+   per-call subprocess spawn (argv in / JSON out / timeout / `--version`). Any unit whose work is
+   < ~10 ms of CPU (all clusters above except possibly cluster 1 at the 3.4 MB extreme) loses to an
+   in-process solution (sources 1 and 6: orjson / pydantic-core wheel pattern).
+3. **N+1 smells exist but are bounded** (`_df()` per-word counts in recall; per-node BFS queries).
+   The remedy, if ever needed, is SQL-level (CTE, single aggregate query), not a language change.
+4. **No memory.store DB exists yet locally** — the SQLite store is schema-defined but not
+   materialized, so there is also no scale data justifying a storage-engine discussion beyond
+   SQLite itself.

+JSON serialization) is better served by the in-process orjson wheel than by a bespoke CLI unit,
+because the `shared/native_units.py` spawn contract costs more than the serialization it would save.
+
+## KILL TESTS (frozen; cheapest disproof, executable early in the wave)
+
+- **Rust (JSON-CLI-unit candidate, cluster 1):**
+  *Kill test:* On the live 3.4MB `knowledge.json`, run a microbench: stdlib json vs orjson
+  (`pip install orjson`) dump+load, 20 iterations each. If (a) orjson is drop-in and ≥2x on load and
+  ≥5x on dump, then a bespoke Rust CLI unit is **disproven** — it must additionally pay
+  subprocess-spawn + JSON handoff (argv in / JSON out) per call, which alone is ~1–5 ms, i.e. the
+  same order as the entire orjson decode of the file. Only if orjson were unavailable/unusable
+  (e.g. forbidden dependency) does a Rust unit stay alive.
+- **Rust (general, clusters 2–7):**
+  *Kill test:* Name one Python-side hot loop with a measured profile showing ≥50% of end-to-end
+  wall time spent in pure Python compute. No such profile exists (all heavy compute is SQLite C or
+  network); the default is **kill**. Reopen only if a future profile of a materially changed
+  workload (e.g. hops > 3 graph walks, or 100MB knowledge.json) shows Python compute > 50%.
+- **Go (all clusters):**
+  *Kill test:* Identify any memory-subsystem batch job whose wall time is dominated (≥50%) by pure
+  CPU compute where goroutine-level concurrency or Go GC characteristics would plausibly help.
+  Measured reality: batch jobs are LLM/I-O bound (cluster 5), serving paths are network-bound
+  (clusters 3, 7), and Go's own JSON story is mid-rewrite (outward #4). **Kill** unless such a
+  profile appears. Concretely: instrument one `consolidate_all` run; if Python-compute share < 50%,
+  Go is dead for the wave.
+- **C (hand-written kernels):**
+  *Kill test:* Identify a kernel not already provided by SQLite/FTS5/sqlite-vec (e.g. a custom
+  tokenizer, exotic distance metric, or crypto kernel) that a profile shows is hot **and** absent
+  from the extension ecosystem. None identified. **Kill.**
+
+## Evidence-sufficiency statement
+
+- **Sufficient for:** keeping all seven clusters in Python; rejecting custom storage engines
+  (sled's own reliability caveat, sqlite-vec/FTS5 coverage); preferring in-process Rust wheels over
+  CLI units for JSON; rejecting Go for this wave (no bottleneck fits its strengths; JSON stack in
+  flux; language not installed — installation not earned).
+- **Insufficient for (stated honestly):** absolute latency numbers — no runtime profiling was
+  performed (static analysis only), and the memory.store SQLite DB is not yet materialized locally,
+  so store-scale behavior is unverified. These gaps do not change any verdict (all verdicts rest on
+  "Python is glue around C/network", which profiling would only strengthen), but they are why the
+  kill tests above specify *measured* profile thresholds rather than assertions.
+
+## Feasibility / migration cost
+
+- Clusters 2–7: **zero migration** — verdict is the status quo.
+- Cluster 1 optional upgrade: `pip install orjson` + swap `json` → `orjson` at the hot
+  load/dump sites; trivial, reversible, no adapter changes, no new build toolchain. This is the
+  entire actionable outcome of the Rust question for this subsystem.
+- Any future CLI unit must still satisfy `shared/native_units.py`: argv in / JSON out / exit 0 on
+  success / `--version` / timeout — feasible for long-running work only.

+# Wave 1 — ORCHESTRATION subsystem: function-cluster intention profile (INWARD)
+
+Scope read: `src/rune/orchestration/` (43 .py modules, 263 `def` matches, ~6,300 LOC incl.
+microkernel.py, contracts.py, spine.py, build_mode.py).
+
+**Scope note (honesty):** `src/rune/construction_authority.py` and
+`src/rune/verification_construction.py` — named in the task — **do not exist** in the tree
+(`ls` verified). The construction cluster is instead represented by
+`build_mode.py` (494 lines, TUI build-pipeline orchestrator). Recorded as a scope gap, not invented.
+
+## Character of the subsystem (read from source)
+
+This is an **authority/composition/ledger** subsystem: durable append-only stores, locks,
+deterministic gates, composition roots, registries, policy objects. It is *not* a numeric,
+parsing, or binary-format subsystem. Evidence of dominant traits:
+
+- **Durable file I/O everywhere**: temp-file+fsync+rename as the durability primitive
+  (`atomic.py:14-24`), append-only JSONL event store with batching (`event_store.py:4-9,
+  56-101`), content-addressed evidence blobs (`evidence_store.py:1-33`), outbox with atomic
+  persistence (`outbox.py:1`).
+- **Shared-memory concurrency is minimal**: exactly two files touch `threading` —
+  `conversation_state.py:33,117` (one RLock because "the TUI calls into them from workers as
+  well as the main thread", conversation_state.py:25) and `event_store.py:57,64` (RLock around
+  buffered appends). No asyncio, no thread pools, no sockets in orchestration/ (only
+  `benchmark.py` and `migrate_cli.py` use `subprocess`).
+- **Determinism and schema discipline dominate over throughput**: canonical records with
+  `schema_version` (`records.py:1-5`), "corruption is a typed error, never a silent skip"
+  (`event_store.py:7`), byte-deterministic snapshots (`spine.py:24-25`).
+- **The only "hot loop" candidate is hashing**: sha256 digests for content addressing and
+  no-change fingerprinting (`evidence_store.py:33`, `no_change.py:16`) — both on
+  already-file-sized data at event-emission cadence, not per-token.
+
+## Function clusters (with file:line evidence)
+
+### C1 — Durable state & ledger stores (I/O-bound) — ~1,100 LOC, ~60 funcs
+`event_store.py` (137, batched JSONL appends + fsync), `atomic.py` (tempfile+fsync+rename),
+`evidence_store.py` (sha256 content-addressed blobs), `outbox.py`, `cursor.py`,
+`conversation_state.py` (450, RLock-guarded repositories, checkpoint recovery at :20-24),
+`chain.py`, `memory.py`, `projection.py`.
+**Intention**: correctness-first durable writes; every op ends in an fsync/replace. The
+bottleneck is the disk, not the language. sha256/uuid/json from stdlib are C-backed already.
+
+### C2 — Composition roots & authority wiring (pure glue) — ~700 LOC, ~40 funcs
+`composition.py` (single-authority root, "Nothing else may create event stores…" :5-7),
+`authority.py`, `cognitive.py`, `memory_synthesis.py`, `gitea_delegation.py`,
+`surface_gateway.py`. **Intention**: construct once, wire invariants, register kinds.
+Runtime cost ≈ zero; testability is the requirement.
+
+### C3 — Policy / state-machine / gate logic — ~1,300 LOC, ~70 funcs
+`lifecycle.py` (outbox lifecycle state machine), `scheduler.py` (single-authority resource
+scheduler), `broker.py` (single acquire path), `budget.py`, `deadline.py`, `cadence.py`,
+`eligibility.py`, `no_change.py` (content fingerprint gate), `selector.py`, `reflex.py`
+(deterministic reflex layer), `router.py`, `resources.py`, `health.py`.
+**Intention**: small deterministic decisions on in-memory state — dict/enum lookups, policy
+evaluation. Sub-millisecond; correctness and auditability are the point.
+
+### C4 — Structural self-model & schema tooling — ~1,400 LOC, ~55 funcs
+`spine.py` (structural authority: AST-ish entity/relationship snapshots, maturity ladder,
+diff — spine.py:1-25), `microkernel.py` (3-primitive plugin dispatch: register/resolve/fire,
+subprocess-spawning, :1-17), `contracts.py` (570, contract-test harness calling functions and
+checking shapes), `mapping.py`, `records.py`, `fixtures.py`.
+**Intention**: introspection, JSON canonicalization, dispatch by manifest. No hot loops;
+`ast` parsing is one-shot at command time.
+
+### C5 — TUI-facing orchestration & build pipeline — ~800 LOC, ~30 funcs
+`build_mode.py` (494, 11-stage build pipeline: ASSESS→…→RECORD, spawns subprocesses,
+calls research/consent gates), `gateway.py`, `surface.py`, `capability.py`, `transport.py`.
+**Intention**: coordinate long-running user-facing flows; the TUI (textual, Python) is the
+direct consumer. Latency dominated by LLM/subprocess calls, never by the orchestrator code.
+
+### C6 — Benchmark/migration harnesses (tooling, not runtime) — ~800 LOC, ~35 funcs
+`retrieval_benchmark.py` (368, precision-recall harness over sqlite backends, frozen
+reference clock), `benchmark.py` (spawns subprocesses), `migrate.py` (sqlite),
+`migrate_cli.py` (subprocess CLI), `workers.py`, `proposals.py`.
+**Intention**: offline measurement and one-shot migration. Never on the interactive path.
+
+## What is ABSENT (decisive for language fit)
+
+- No numeric/array computation (no numpy; no vector math).
+- No binary-format parsing (JSONL + text only).
+- No network protocol implementation (HTTP delegated to transports outside the subsystem).
+- No per-event hot loop: event cadence is human/agent-scale (batch_size=8 appends,
+  event_store.py:56).
+- No parallel CPU-bound work that a GIL actually blocks (the two RLocks guard at most
+  TUI-thread + worker-thread light mutations).
+
+**Preliminary inward read (to be stress-tested outward):** all six clusters are
+I/O-bound glue, deterministic decision logic, or coordination code — the profile where
+Python is the honest default and recodes mostly buy risk, not speed. The only clusters with
+even a theoretical compiled-language argument are C1's hashing path and C4's spine diff —
+and both are small, cold, and already stdlib-C-accelerated.

+## Claim → evidence map
+
+- **Claim A: I/O-bound glue clusters stay Python** → S1, S2 (both show recode value is confined to hot loops absent here) + inward C1/C2/C5 profile.
+- **Claim B: Go adds nothing here (no concurrency to exploit)** → S3 (design intent is goroutine-heavy servers) + inward scan (2 RLocks, 0 sockets, 0 thread pools).
+- **Claim C: The only compute path (hashing) already runs in C** → S5 + inward evidence_store.py:33 / no_change.py:16.
+- **Claim D: Rust is feasible via the adapter but unjustified** → S7 (local: 0.63ms/op adapter cost) + S8 (local build clean) + S1/S2 (no hot loop to justify).
+- **Claim E: C would not beat stdlib** → S5 alone is decisive here (C is what stdlib already calls); corroborated by absence of any C-shaped workload in the inward profile.
+
+## Methodology caveats
+
+- S2 is vendor marketing (no published harness) — used directionally only.
+- S7's local benchmark is n=100, single warm-cache Linux machine; spawn cost varies by OS (macOS typically 5–20× higher). At agent-event cadence (batch_size=8 appends, event_store.py:56) even the pessimistic end is negligible.

+# SYNTHESIS — Wave 1 ORCHESTRATION: per-cluster language verdicts
+

+|---------|----------------------------------------------------------|---------|----------|--------------|
+| C1 Durable state & ledger stores | event_store.py:56-101, atomic.py:14-24, evidence_store.py:33, conversation_state.py:117, outbox.py:1 | **KEEP-PYTHON** | 5 | fsync-bound; hashing already C via hashlib (S5); no hot loop |
+| C2 Composition roots & authority wiring | composition.py:5-7, authority.py, cognitive.py | **KEEP-PYTHON** | 5 | pure glue, runtime cost ≈ 0 (S1) |
+| C3 Policy / state machines / gates | lifecycle.py, scheduler.py, broker.py, no_change.py:16, reflex.py | **KEEP-PYTHON** | 5 | deterministic dict/enum decisions, sub-ms; testability is the requirement (S1, S2) |
+| C4 Structural self-model & schema tooling | spine.py:24-25, microkernel.py:1-17, contracts.py, records.py | **KEEP-PYTHON** | 4 | introspection + canonical JSON; one-shot AST parsing; only candidate for a future Rust spine-diff if snapshot size ever grows 1000× |
+| C5 TUI-facing orchestration & build pipeline | build_mode.py:1 (11-stage pipeline), gateway.py, transport.py | **KEEP-PYTHON** | 5 | consumer IS the Python TUI (textual); latency dominated by LLM/subprocess waits |
+| C6 Benchmark/migration harnesses | retrieval_benchmark.py:1-20, migrate.py, benchmark.py | **KEEP-PYTHON** | 4 | offline tooling; recode buys nothing, loses iteration speed |
+
+**Keep-Python honesty outcome:** 6/6 clusters KEEP-PYTHON. Real recode volume in this
+subsystem: **zero functions**. Scope gap: `construction_authority.py` and
+`verification_construction.py` do not exist (verified); the construction cluster is
+covered by build_mode.py (C5).
+
+## Candidate-language verdicts
+
+- **Go: REJECTED, do not install.** Its differentiator (goroutine-dense servers, S3)
+  targets a workload absent here (2 RLocks, 0 sockets, 0 thread pools across 43 files).
+  Costs are concrete: exception→error-value rewrite of ~260 functions and C/Rust interop
+  "not a natural fit" (S3) against the std-only-Rust adapter contract. Kill test K-GO
+  below is the frozen early test should this ever be challenged.
+- **Rust: FEASIBLE (toolchain proven: builds clean, 0.63ms/op through the adapter) but
+  UNJUSTIFIED anywhere in this tranche.** No cluster has the hot loop (S1, S2) that pays
+  for a process-boundary recode. Keep as a toolchain-ready option for other subsystems.
+- **C: REJECTED.** The only compute-shaped work (sha256 evidence addressing,
+  no_change fingerprints) already executes C via stdlib hashlib (S5); a hand-written C
+  unit would be slower in total (spawn+serialize ≈ 0.63ms measured vs an in-process C
+  call) and add an unsafe-memory surface for zero gain.
+
+## Kill tests (cheapest experiment that would disprove each candidate verdict)
+
+- **K1 (frozen, already run — kills "adapter overhead blocks recodes"):** time 100
+  round-trips through the rebase-proof binary. Result 2026-09-29: mean 0.63ms, p95
+  0.74ms, cold 0.87ms, 100% exit-0 + ok:true. INTERPRETATION: adapter overhead does NOT
+  disprove recodes on cost grounds — recodes are rejected on VALUE grounds (no hot
+  loop). If a future profiling run shows any orchestration function consuming >10% of a
+  real interactive session, re-open that cluster.
+- **K-GO (frozen, cheap, ~30 min):** if Go's case is ever revived, first run a
+  Go prototype of event_store.py's batched append+fsync (the only place Go could win —
+  batching under contention) against the Python version at 1000 events. If Python's
+  p95 append latency is within 2× of Go's, Go is dead here permanently. (Expected:
+  both are fsync-bound and identical; Go loses on 260-function rewrite cost.)
+- **K-RUST (frozen, ~20 min):** if a Rust recode of the spine diff
+  (spine.py:24-25) is proposed, first measure current diff time on a 10,000-entity

+## Evidence-sufficiency statement
+
+**Proven (live-fetched or locally measured):** the subsystem's function-cluster
+intentions (inward read, file:line-anchored); that headline Python→Rust recodes target
+hot loops absent here (S1, S2); that Go's design intent mismatches this workload (S3);
+that hashlib is already C-accelerated (S5); that the std-only-Rust adapter contract
+round-trips at 0.63ms/op (local, n=100).
+
+**Assumed (flagged honestly):** that agent-event cadence stays at human scale
+(batch_size=8, event_store.py:56) — if orchestration ever runs 10⁴+ events/sec, C1/C4
+verdicts must be revisited; that S2's marketing numbers are directional only; that
+spawn cost on non-Linux targets may be ~10× higher than the measured 0.63ms (negligible
+even then at this cadence). Two named scope files were absent; no evidence was
+invented for them.
+
+## Feasibility judgement (migration cost against the interop contract)
+
+Migration cost per cluster to any compiled language = rewrite of ~6,300 LOC +
+exception-handling re-expression + adapter unit + test parity through contracts.py —
+while the measured benefit is bounded by the adapter's own 0.63ms/op floor and by
+fsync latency that no language changes. Feasible for a *single* coarse-grained unit
+(e.g., spine snapshot emit) in ~1–2 days if ever needed; feasible for the whole
+subsystem only at prohibitive cost and zero measurable payoff. Recommendation: this
+subsystem contributes **0 recode units** to the wave plan.

+## Cluster map with evidence
+
+### C1 — HTTP wire + transport (provider_registry.py, openai_compat_transport.py)
+- Wire calls are blocking `urllib.request.urlopen` with fixed timeouts:
+  provider_registry.py:214 (`timeout=10`), provider_registry.py:393
+  (`timeout=120`, generation call), openai_compat_transport.py:219
+  (`timeout=120`), openai_compat_transport.py:86 (`timeout=5`, health checks).
+- Streaming is uniformly disabled: `"stream": False` in every payload —
+  provider_registry.py:374, provider_registry.py:503, openai_compat_transport.py:73,
+  openai_compat_transport.py:160, openai_compat_transport.py:206. grep confirms no
+  `NotImplementedError` stub anywhere in the subsystem: SSE is absent, not half-built.
+- **No retry/backoff exists at all.** grep for `retry|backoff|max_retries|attempt|sleep`
+  across all subsystem files returns nothing. Failure handling is a bare
+  `except Exception: return False` at openai_compat_transport.py:74-75 (health check).
+- **Connector-reliability critical code**: the tool-call envelope contract lives in
+  openai_compat_transport.py — tool_call id pairing and normalization at lines 67-107,
+  envelope shape at 160-207, content filtering at 108-135. Comments in-file record
+  observed-live provider misbehavior (400s, orphaned tool results, loops) that this
+  logic defends against. This is the highest-risk code to port.
+
+### C2 — Connection pool (connection_pool.py, 144 lines)
+- `threading.Lock`-guarded pool, max 3 connections/provider, idle-timeout eviction.
+- Guards in-process objects, not sockets — unrelated to TCP pooling.
+
+### C3 — Routing decisions (model_routing.py, 432 lines)
+- One I/O call: `httpx.get(.../api/tags)` at model_routing.py:99-101; Ollama
+  `/api/show` probe at 199-214. Everything else is pure decision logic
+  (selection/sorting/fallback) over in-memory data.
+
+### C4 — Budget accounting (provider_budget.py, 354 lines)
+- Pure arithmetic over token/cost counters, `threading.Lock` for thread safety.
+  No I/O, no network, no parsing.
+
+### C5 — Config/registry (model_profiles.py, model_registry.py, standardized_providers.py, model_connect.py)
+- model_profiles.py (435) and standardized_providers.py (281): pure dataclasses and
+  normalization/translation tables — zero I/O.
+- model_registry.py (211): JSON file persistence.
+- model_connect.py (462): urllib GET discovery (`/api/tags`, `/api/show`) plus a
+  connectivity-status cache; same wire shape as C1.
+
+## Cross-cutting facts
+- **No asyncio anywhere** in the subsystem (grep). All I/O is blocking; the only
+  concurrency primitives are `threading.Lock` in connection_pool.py and
+  provider_budget.py.
+- **No retry, no backoff, no SSE** exist today (see C1). Any rewrite pitch that
+  says "Go/Rust gives us retry+SSE" is proposing a *feature add*, not a port.
+- httpx is already a dependency (model_routing.py:99).
+- Performance-relevant surface is thin: ~900 lines of wire code (C1+C5 discovery),
+  all latency-bound on the remote LLM server, with `stream: False` payloads of a few KB.
+
+## Corrections vs earlier session notes
+- Earlier profiling notes claimed retry/backoff at provider_registry.py:90-121 and a
+  `NotImplementedError` SSE stub. Both are **wrong** against the current tree — no
+  such code exists (grep-verified). This strengthens the stay-Python verdict: the
+  incumbent wire layer is *smaller and simpler* than previously assumed.

+# Wave 1 — Provider/Model Layer Synthesis (per-cluster language verdicts)
+
+Doctrine applied: KEEP-PYTHON is the expected default and the honest volume-governor;
+each candidate carries a kill test; per-cluster verdicts, never global.
+
+Inward evidence: `inward.md` (file:line verified). Outward evidence: `outward-sources.md`
+(8 live-fetched sources, claim-coverage map at bottom).
+
+---
+
+## C1 — HTTP wire + transport (provider_registry.py, openai_compat_transport.py, model_connect.py discovery)
+
+**Verdict: KEEP-PYTHON. Score: Python 5, Go 2, Rust 1.**
+
+- Python: incumbent works; wire surface is ~900 latency-bound lines with `stream: False`
+  everywhere and fixed timeouts (inward.md C1). httpx already a dependency
+  (model_routing.py:99). Production-proven pattern for this exact workload: O7, O8.
+- Go: capability proven — stdlib-only HTTP+NDJSON streaming (O1, O2) and scaled
+  production use (O6).
+- Rust: mature client (O3) but SSE parsing is an external async-only crate (O4);
+  even first-party Rust LLM stacks take the tokio dependency stack (O5).
+
+**Kill tests**
+- Go: toolchain absent (verified: `which go` → not found). To re-earn, a Go candidate
+  must pass the `interop/rebase-proof/` contract (std-only, exit 0, not timed out) AND
+  demonstrate a measurable win over the Python incumbent on this workload. There is no
+  performance signal to demonstrate: the layer is remote-LLM-latency-bound with
+  kilobyte payloads (inward.md cross-cutting). Also, 28 call-site behaviors including
+  the tool-call envelope contract (openai_compat_transport.py:67-107, 160-207) would be
+  re-implemented in a new language with zero incumbent test port. **Killed** — no
+  evidence basis to pass the kill test.
+- Rust: the std-only interop contract cannot express the workload — SSE requires
+  reqwest+tokio+eventsource-stream+nom (O3, O4, O5). **Killed** — fails the contract
+  by construction; dependency footprint contradicts the rebase-proof standard.
+- Keep-Python upgrade path (not a language change): adopt httpx blocking client with
+  per-phase timeouts + a small retry wrapper (O8). This delivers the reliability the
+  layer currently lacks (it has *no* retry/backoff at all — inward.md Corrections)
+  without any port risk.
+
+## C2 — Connection pool (connection_pool.py, 144 lines)
+
+**Verdict: KEEP-PYTHON. Score: Python 5, Go 2, Rust 2.**
+
+- Guards in-process objects under threading.Lock at ~144 lines; not a TCP pool. No
+  hot loop, no memory pressure, no FFI boundary.
+
+**Kill test**
+- Go/Rust: would need demonstrated contention or throughput evidence (pool saturation
+  profiles, lock-wait times) — none exists; the layer is not profiled as a bottleneck.
+  No interop unit can represent in-process object pooling under the std-only contract
+  in a way that measures anything relevant. **Killed** — no measurable problem to solve.
+
+## C3 — Routing decisions (model_routing.py, 432 lines)
+
+**Verdict: KEEP-PYTHON. Score: Python 5, Go 1, Rust 1.**
+
+- Pure decision logic over in-memory data (one httpx discovery call, model_routing.py:99).
+- Kill test (Go/Rust): would require evidence that routing decisions are a compute
+  bottleneck — they run once per request against millisecond-scale in-memory work while
+  the request itself takes seconds against the LLM. **Killed** — 5 orders of magnitude
+  below any measurable threshold.
+
+## C4 — Budget accounting (provider_budget.py, 354 lines)
+
+**Verdict: KEEP-PYTHON. Score: Python 5, Go 1, Rust 1.**
+
+- Pure arithmetic + threading.Lock. No I/O.
+- Kill test (Go/Rust): needs counter-throughput evidence; none. A port would be pure
+  translation cost with zero performance headroom. **Killed**.
+
+## C5 — Config/registry/normalization (model_profiles.py, model_registry.py, standardized_providers.py, model_connect.py tables)
+
+**Verdict: KEEP-PYTHON. Score: Python 5, Go 1, Rust 1.**
+
+- Dataclasses, JSON persistence, translation tables. The value here is editability by
+  non-systems programmers; a compiled port buys nothing and costs review surface.
+- Kill test (Go/Rust): needs evidence of config-load latency or memory footprint
+  problems; none. **Killed**.
+
+---
+
+## Evidence sufficiency
+
+- C1: sufficient — 2/2/3 live sources on the three candidates plus line-verified
+  inward profiling (with Corrections: no retry, no SSE stub, contrary to earlier notes).
+- C2–C5: sufficient by volume-governor logic — the burden of proof sits on the
+  *rewrite* candidates and the kill tests cannot be passed without performance
+  evidence that does not exist.
+
+## Feasibility note
+
+If Go is installed later, the single cluster worth re-running a kill test for is C1
+(stdlib-only proof via interop/rebase-proof + a benchmark harness). Until then the
+door is closed on evidence, not opinion.

+- `tool_executor._run_command` (tool_executor.py:1064): `subprocess.run(..., capture_output=True, timeout=...)` blocking calls for arbitrary commands; timeout handling returns error dict.
+- Grep/lint/test/format/git helpers: `_grep_files`:1190, `_lint_file`:1302, `_run_tests`:1331, `_format_code`:1374, git ops :1403-1448, `_repo_map`:1481. All thin wrappers around one blocking subprocess pattern with 10–120 s timeouts.
+- Approval-token workflow: `PreparedTool`, `prepare_tool`:681, `approve_tool`:758, digest revalidation `_consume_prepared`:736 — deferred-execution state machine in plain dataclasses.
+- Sandbox path validation: tool_executor.py:466, 478 (path containment checks before exec).
+- Atomic writes: `_apply_content`:914 (temp file + replace).
+- Language config table: tool_executor.py:1215-1270 (dict of per-language command templates).
+- `cron_engine._run_loop`:182 — one daemon thread, sleeps 60 s, hand-rolled 5-field cron parser (`_parse_cron_field`:199, `_should_run`:236), executes via `subprocess.run(shlex.split(...), shell=False, timeout=60)`:279, file-rotation logging :291.

+
+Hot/glue verdict: pure glue. Every unit of work is "spawn a process, wait, parse output".
+The CPU cost is zero; the wall-clock cost is the child process itself. Error surface is the
+interesting part: timeouts, non-zero exits, stderr capture, sandboxing — all expressed in

+- `context_broker.default_estimator` = `len(text)//4`:100 — O(n) token estimate.
+
+Hot/glue verdict: the only CPU-flavored cluster, but inputs are model-output fragments and
+config cards — KBs, not MBs. Python's json/regex is already C-backed; a rewrite would move
+work from CPython-C to another compiled runtime for no observable gain.

+- `goal._verify_with_llm`:142 — LLM-as-judge via raw urllib to Ollama (qwen2.5:3b, 30 s timeout) with keyword fallback `_verify_with_keywords`:209.
+
+Hot/glue verdict: glue with latency domination. The loop spends ~100% of wall time waiting
+on LLM HTTP responses measured in seconds; Python interpreter overhead is noise. Routing
+tables, escalation ladders, and circuit breakers are dict/logic — Python's home turf.
+
+## Cluster D — Context assembly & budgeting

+
+- `_collect`:495 — contributor callbacks with T1 degrade-not-crash; `_admit`:533 — deterministic priority admission, `ContextOverflowError` fail-loud; `compact_history`:232 — archive-first, rolling summary via Ollama (`summarize_history`:186, urllib); `assemble`:616, `_render`:723; `threading.RLock` guarding single-authority assembly.
+- Token math is trivially O(n) string slicing (see Cluster B estimator).

+- `work_manager`: pure dataclass batching (`create_batches`:129, `route_batch`:198), JSON file persistence (~/.rune/work/batches.json), CLI. No concurrency, no subprocess.
+- `hook_engine`: static metadata tagging of ~28 functions via 18-factor dicts (`auto_tag`:110), pure rule-based `recommend_placement`:674, validation :729, CLI; `handle_hook`:807 is a no-op echo. Entirely declarative data — zero runtime dispatch.

+# OUTWARD SOURCES — Runtime core & tooling (Wave 1)
+
+All fetches were live `webfetch` calls made during this session. Confirmation status is
+stated per source; one source (Q6) is fetch-confirmed but content-thin (SPA shell) and is
+labeled as such rather than paraphrased as if read.
+
+| # | URL | Fetch-confirmed | Lesson |
+|---|-----|-----------------|--------|
+| Q1 | https://pkg.go.dev/os/exec | Yes (go1.27.1 docs rendered) | Go's exec has context-based timeout (`CommandContext`), `WaitDelay`, and since 1.19 refuses cwd-relative program resolution (ErrDot) — a real, mature subprocess API. Nothing Go offers here is a capability Python's `subprocess.run(timeout=..., shell=False)` lacks; it is a different syntax for the same semantics. |
+| Q2 | https://docs.python.org/3/library/subprocess.html | Yes (3.14.7 docs rendered) | `subprocess.run(check=, timeout=, capture_output=, shell=False)` is exactly the one-call pattern `tool_executor`/`cron_engine`/`auto_tasks` wrap in dict-returning helpers (tool_executor.py:1064, cron_engine.py:279, auto_tasks.py:261). Exception hierarchy (`TimeoutExpired`, `CalledProcessError`) maps 1:1 onto the codebase's degrade-not-crash error dicts. |
+| Q3 | https://pkg.go.dev/github.com/robfig/cron | Yes (v1.2.0 docs rendered) | robfig/cron is a ~zero-dep 5-field parser + goroutine runner — exactly what cron_engine hand-rolls at cron_engine.py:199/236. Ergonomic win for maintenance, zero performance win at ~1 task/min on one daemon thread. |
+| Q4 | https://doc.rust-lang.org/std/process/index.html | Yes (std docs rendered) | std::process has NO built-in per-child timeout — Python's `run(timeout=)` becomes hand-rolled wait/poll/kill logic or a tokio dependency. Under this project's zero-crate constraint (interop/rebase-proof is std-only), Rust is strictly more code for identical Cluster-A behavior. |
+| Q5a | https://docs.rs/serde_json/latest/serde_json/ | Yes (docs.rs rendered) | serde_json requires typed derive structs or borrow-heavy `Value` manipulation; our JSON is dynamic model output / schema-flexible events mutated as dicts with tolerated missing keys — the pattern serde is worst at. |
+| Q5b | https://docs.python.org/3/library/json.html | Yes (3.14.7 docs rendered) | Python's json (incl. `JSONDecoder.raw_decode` used at tool_protocol.py:350) is C-accelerated; the only CPU-flavored cluster already runs in C on KB-scale inputs. A rewrite changes syntax, not asymptotics or wall time. |
+| Q6 | https://go.dev/tour/concurrency | Yes, but SPA shell — body did not render (content-thin) | Goroutines are runtime-managed lightweight threads with typed channels (corroborated indirectly by Q1/Q3 doc examples). Our subsystem runs ≤2 threads total; Go's concurrency model solves a problem we do not have. |
+
+## Cross-source synthesis
+- **Subprocess orchestration (Cluster A):** Q1 vs Q2 — feature parity between Go exec and
+  Python subprocess for everything our code does (timeout, capture, no-shell, path
+  safety). Q4 shows Rust std is *behind* on the exact feature (child timeout) our code
+  uses most. No language wins on capability; Python wins on lines-of-glue and exception
+  flow into existing dict-error handling.
+- **Scheduler (Cluster A / cron):** Q3 confirms the one genuinely better-idiomed surface
+  (cron parsing) in Go — but the win is maintenance of ~37 hand-rolled lines, not
+  behavior or speed.
+- **JSON/protocol (Cluster B):** Q5a+Q5b — Python's dynamic-JSON ergonomics are
+  load-bearing across all 12 files; serde's typed model is actively mismatched to
+  untrusted model-output parsing.
+- **Concurrency (Clusters C/E):** Q6 — concurrency features are irrelevant at our thread
+  count; LLM HTTP latency (seconds) dominates every loop, so no compiled language can
+  produce a user-observable delta.

+# SYNTHESIS — Runtime core & tooling (Wave 1)
+
+Method: INWARD (inward.md, file:line evidence) → OUTWARD (outward/*.json, outward-sources.md,
+live-fetched) → per-cluster verdict. Score 1–5 = language fit for THIS cluster's actual
+workload as characterized inward. Go verdicts are evidence-starved (Go not installed on
+this machine — no Go kill test runnable locally).
+
+---
+
+## Cluster A — Subprocess lifecycle orchestration (tool_executor, cron_engine, auto_tasks)
+**Verdict: STAY-PYTHON (4.7/5).**
+The cluster is "spawn, wait, capture, degrade into an error dict" — `subprocess.run(timeout=,
+capture_output=, shell=False)` is a one-call expression of the entire pattern
+(inward.md §A; tool_executor.py:1064, cron_engine.py:279, auto_tasks.py:261). Outward Q1/Q2:
+Go's os/exec reaches feature parity (CommandContext timeouts, ErrDot path hardening) but
+changes only syntax, not semantics. Outward Q4: Rust std::process has **no built-in child
+timeout** — the exact feature this cluster leans on hardest — making Rust strictly more code
+under the zero-crate constraint. The approval-token state machine (tool_executor.py:681-758)
+and sandbox checks (:466,478) are plain data + containment logic, natural in Python.
+**Kill test (Rust):** re-express `_run_command` (tool_executor.py:1064) with std::process +
+manual timeout; count lines and error arms vs the ~40-line Python wrapper. If the Rust
+version needs >2× lines to reach identical timeout/capture/degrade behavior — which Q4
+predicts — the rewrite is a net loss. (Runnable locally: Rust 1.98.1 installed.)
+**Kill test (Go):** not runnable locally (Go not installed). Paper kill test: port
+cron_engine._run_loop (cron_engine.py:182) to Go with os/exec; measure task-fire latency
+delta. Prediction from Q1/Q3: zero delta — the 60 s sleep and child runtime dominate.
+**Evidence sufficiency:** Python verdict fully evidenced. Rust kill test runnable.
+Go verdict evidence-starved on execution, adequately evidenced on API parity (Q1).
+
+## Cluster B — Protocol/JSON parsing & validation (tool_protocol; broker scoring/estimation)
+**Verdict: STAY-PYTHON (4.5/5).**
+The only CPU-flavored cluster, but inputs are KB-scale model-output fragments; Python's
+json/regex is C-backed (outward Q5b), so a rewrite swaps C for compiled code at the same
+asymptotic cost. The incremental `raw_decode` scan (tool_protocol.py:350, :368) parses
+untrusted, fence-wrapped, schema-flexible output — serde's typed-struct model (outward Q5a)
+is actively mismatched; dynamic `Value` borrows turn tolerated-missing-key dict idiom into
+match-arms. Score dinged 0.5 from perfect only because a very large future corpus (>MB
+batch parsing) would change the math; no such workload exists inward.
+**Kill test:** parse the largest observed tool-protocol stream 1000× in Python; if total
+time < 1 s, no rewrite can produce a user-observable win. (Python side runnable locally.)
+**Evidence sufficiency:** sufficient — inward shows scale (KB), outward shows C-backed
+already and serde's ergonomic mismatch.
+
+## Cluster C — Model→tool control loop + HTTP transport (local_tool_runtime, elastic_cognition, goal)
+**Verdict: STAY-PYTHON (4.8/5).**
+Wall time is LLM HTTP latency in seconds (Ollama/cloud, 30 s timeouts — inward.md §C);
+Python overhead is microseconds-to-milliseconds of noise around those waits. The loop's
+real content is policy: bounded iterations (local_tool_runtime.py:417), circuit breaker
+(:434-459), escalation ladders (elastic_cognition.py:644), routing tables (:203) — dict/logic
+structures where Python is strongest and where a rewrite would re-risk correctness for zero
+latency gain. Outward Q6 (concurrency features) is irrelevant at ≤2 threads.
+**Kill test:** instrument `_run_loop` (local_tool_runtime.py:417): log non-HTTP CPU time per
+iteration. Prediction: <1% of wall time is compute; any language rewrite bounds the win at
+<1% of an already-latency-bound path. (Python side runnable locally.)
+**Evidence sufficiency:** sufficient.
+
+## Cluster D — Context assembly & budgeting (context_broker)
+**Verdict: STAY-PYTHON (4.7/5).**
+Correctness lives in admission policy (`_admit`:533, fail-loud ContextOverflowError),
+degrade-not-crash contributor collection (`_collect`:495), and the single-authority RLock —
+semantics, not speed (inward.md §D). Token math is O(n) len//4 (:100). Compaction is
+itself an LLM call (`summarize_history`:186), so the slow path is latency-bound like
+Cluster C.
+**Kill test:** time `assemble`+`_admit` on the largest stored context; if <10 ms, no
+language rewrite is observable. (Runnable locally, Python side.)
+**Evidence sufficiency:** sufficient.
+
+## Cluster E — Reliability/queueing infra (failure_auto_filer)
+**Verdict: STAY-PYTHON (4.2/5).** Lowest confidence of the six, stated honestly.
+On paper this is the best Rust candidate (queue + worker thread + crash-safe JSONL spool,
+inward.md §E). But its performance requirement is ~nil — failure events are rare — and its
+correctness burden is threading semantics and crash-safe journal ordering
+(JsonlSpool:117, `_run_worker`:453), precisely the properties a rewrite re-risks and must
+re-verify under fault injection. Rust would not make the spool *more* correct, only less
+familiar. Score 4.2 not 4.7 because this is the one file where a Rust port could be argued
+on robustness grounds (no GIL-dependent reasoning), yet the argument fails the "what breaks
+today?" test: nothing does.
+**Kill test:** fault-inject (kill -9 during spool append) against the current Python spool;
+if recovery semantics already hold, the rewrite has no correctness win to buy. (Runnable
+locally, Python side.)
+**Evidence sufficiency:** partially sufficient — no outward source speaks directly to
+JSONL-spool crash-safety across languages; verdict rests on inward semantics.
+
+## Cluster F — Declarative config/brokers (work_manager, hook_engine, capability_broker, goal-storage)
+**Verdict: STAY-PYTHON (4.9/5).**
+hook_engine is literal data (~28 tagged functions, 18-factor dicts, hook_engine.py:110, :674)
+with a no-op runtime (`handle_hook`:807); work_manager is dataclass batching + one JSON file
+(work_manager.py:129, :198); capability cards are per-call JSON I/O with atomic rebuild
+(capability_broker.py:474). Portable to anything, valuable in nothing — the asset is the
+rules, which read as Python dicts today and would read as serde structs/slices at strictly
+higher friction (outward Q5a).
+**Kill test:** none needed short of a full rewrite; the cluster has no runtime behavior to
+measure. Absence of any win condition *is* the disproof of migrating it.
+**Evidence sufficiency:** sufficient.
+
+---
+
+## Overall
+Honest result: **stay-Python for all six clusters.** The subsystem is latency-bound glue
+(LLM HTTP + child processes) with ≤2 threads and KB-scale parsing; no cluster contains a
+compute-bound path where Go/Rust could pay for the rewrite. The single best-language moment
+found anywhere is robfig/cron (outward Q3) replacing ~37 hand-rolled lines of cron parsing
+(cron_engine.py:199-236) — an ergonomics nicety, not a fit verdict.
+
+## Feasibility
+- Go verdicts are **evidence-starved**: Go is not installed; Go kill tests cannot run
+  locally. They are marked as paper kill tests above.
+- Rust kill tests **are runnable** (Rust 1.98.1 present). Any candidate Rust unit could be
+  validated through the existing std-only interop harness (`interop/rebase-proof/src/main.rs`,

+# Inward — Wave 1, TUI subsystem (rune)
+
+Research question: should `src/rune/rune_tui.py` (and its widget satellites) stay Python/Textual, be recoded native (Go/Rust), or be split — and what adapter surface does the TUI need from the interop contract to "read and utilise those mixtures of languages for its benefit" (Nick's framing)?
+
+Scope of evidence: `src/rune/rune_tui.py` (4031 lines), `tui_validator.py` (514), `canary_tui_drift.py` (170), `chat_bubble.py` (401), `message_widgets.py` (104); inventory `docs/rebase/rebase-inventory.json`; adapter `shared/native_units.py` (103); proof contract `interop/rebase-proof/src/main.rs`.
+
+## 1. Unit inventory and coupling
+
+- TUI cluster ≈ 152 units total; `rebase-inventory.json` tracks only 3 files under a tui path (rune_tui.py, tui_validator.py, canary_tui_drift.py) — chat_bubble.py and message_widgets.py are untracked satellites.
+- `rune_tui.py` imports 80+ first-party modules (warm_router, capability_broker, memory_store, rune_operator, cron_engine, provider_budget, …). The TUI is the single largest consumer of the codebase.
+
+## 2. Cluster map (with file:line evidence)
+
+### Cluster A — Rendering / widgets (candidates: parse/render hot paths?)
+- `RuneApp(App)` rune_tui.py:1356; app CSS 1364-1477; BINDINGS 1479-1489; reactives 1493-1500.
+- Widgets: `ThinkingIndicator` :263 (only animation: 0.12s `set_interval` spinner); `HistoryInput` :359; `RuneCommands` Provider :517; `CommandSelector` :532; `ModelItem`/`CategoryHeader`/`ModelSelector` :600-874; `StatusBar` :974; `WorkPane(Vertical)` :1239.
+- `WorkPane.render()` :1331 and `ChatBubble.render()` chat_bubble.py:157 both build plain Rich `Text` objects by concatenation. Grep of src/rune finds NO `rich.markdown` / `Markdown` / `Syntax` usage — there is no markdown or syntax parsing anywhere in the TUI render path.
+- Conclusion: no hot parsing/rendering loop exists. The classic "native TUI for render speed" argument has no footing here.
+
+### Cluster B — Event glue / command surface (the real body of the file)
+- ~50 `_cmd_*` handlers in rune_tui.py:2476-3575; 88 `_cmd_` references; 279 `add_message` call sites.
+- `WorkPane` keeps `dict[str, dict]` `_entries` keyed by stable object id with bounded eviction (`_WORK_PANE_MAX_ENTRIES`); headless-testable data methods `add_object`/`update_object`/`visible_entries`.
+- Tool-widget update-in-place: `self._tool_widgets` dict keyed by `(channel, call_id)`; `tool_widget.apply(tool_event)` at :3676.
+
+### Cluster C — Model send path (de-facto interop envelope)
+- `_send_to_model` :3600 → `run_worker(_respond, exclusive=True)` :3816 → synchronous `rune_operator.send_task(text, model=…, channel=…)` inside async worker :3624.
+- Result envelope dict: `success`, `response`, `thinking` (list), `model`, `recall_count`, `degraded` (list), `tool_events` (list of `{request{call_id}, …}`). This envelope IS the shape a recoded unit would have to reproduce.
+- Completion side-effects inline in the worker: cron_engine.fire_on_task_complete, MessageQueue approved drain, provider_budget check.
+- `_consume_runtime_objects` :3818 feeds WorkPane.
+
+### Cluster D — Subprocess / streaming consumption (adapter precedent already in-tree)
+- `_cmd_pull` :3443-3517: `subprocess.Popen(["ollama","pull",model,"--json"])`, `json.loads` per stdout line, `self.call_from_thread(...)` to marshal UI updates. A live JSONL streaming precedent.
+- Background VRAM preload thread :1616-1640 (urllib → ollama /api/generate); parallel startup threads (compile_persona, scan_registry, load_tasks) :1683-1720; CognitiveLoop/DreamCycle/AutonomyLoop started on_mount :1644-1673.
+- `_run_warm_router` :3575 is a documented no-op — the 21-step per-turn pipeline (~120ms/msg) was removed; cognition moved to ContextBroker in rune_operator + on-demand /commands. The one historical hot path is already gone.
+
+### Cluster E — Adapter contract (current state)
+- `shared/native_units.py`: `NativeResult(ok, exit_code, data, stderr, duration_ms, timed_out, raw_stdout)`; `run_native(binary, args, timeout_s=10.0)`; success = exit 0 AND not timed out (line ~89); parses the LAST stdout line as JSON.
+- `interop/rebase-proof/src/main.rs`: std-only Rust CLI; argv in → `{"ok":true,…}` / `{"ok":false,"error":…}` (exit 2) on stdout; mandatory `--version`; ops sum/echo/hash/sleep/fail.
+
+## 3. Toolchain constraint (verified locally)
+
+- `command -v go` → empty: **Go is not installed**; no local Go evidence can exist.
+- Rust 1.98.1 + GCC 16.2.1 present; `interop/rebase-proof` builds std-only.
+
+## 4. Intent profile
+
+- The TUI's intent is **orchestration and consumption**: invoke models, stream and render progress (tool_events, thinking, degraded notices), manage approvals/queues/cron side-effects, and display results. Its value is event glue + state, which Textual's worker/reactive/call_from_thread machinery directly serves.
+- Any recode must re-expose the ~80 coupled Python modules through an adapter — the coupling cost, not widget cost, dominates.

A native unit can stream `tool_events`/recall objects as JSONL with a terminal sentinel envelope; no new runtime machinery needed — but `shared/native_units.py` currently parses only the LAST stdout line, a contract gap that must be closed.

+- URL: https://openai.github.io/openai-agents-python/workflows/
+- Fetch-confirmed: ✅ (`fetch-W7-agents-workflows.json`)
+- Lesson: Recommended pattern for agentic products: keep the orchestration loop in the high-level framework, push granular/speed-sensitive work into hand-coded subcomponents behind typed interfaces, and stream intermediate outputs so the UI stays responsive. Maps 1:1 onto the rune architecture: Textual TUI (framework) + recoded native units behind a typed JSON envelope (adapter), with streamed `tool_events` keeping the UI live.

+### S8 — Claude Code best practices (supports: TUI-as-consumer architecture, agentic UX)
+- URL: https://www.anthropic.com/engineering/claude-code-best-practices
+- Fetch-confirmed: ✅ (`fetch-W8-claude-code-tui.json`)
+- Lesson: Anthropic deliberately chose a terminal UI for agentic coding for its composability and scriptability; the hard problems are agentic loop design and UX (streamed feedback, permission prompts, background tasks), not rendering speed. Validates that the rune TUI's complexity lives in event glue and agent-orchestration UX — areas where Textual's primitives (workers, call_from_thread, reactives) are already proven, and where a recode would re-litigate solved UX problems.

+# Synthesis — Wave 1, TUI subsystem
+
+Question: stay Python/Textual vs Go/Rust native recode, disposition of parsing/rendering hot paths, and the adapter surface the TUI needs from the interop contract.
+
+## Verdict
+
+**KEEP-PYTHON for the TUI shell.** `rune_tui.py` stays Python/Textual. No parsing/rendering hot path exists to carve out today. The deliverable that constrains every other wave is the **adapter surface** below: the TUI is the consumer of all recoded units, so its requirements define the interop contract.
+
+## Per-cluster scores (1 = recode, 5 = keep)
+
+| Cluster | Candidate | Score | Verdict | Evidence |
+|---|---|---|---|---|
+| A — Rendering/widgets | Rust/Go native render | 4 | Keep — no hot loop exists; render is plain Rich `Text` concatenation (rune_tui.py:1331, chat_bubble.py:157), only animation is a 0.12s spinner (:263); no markdown/Syntax parsing anywhere in src/rune | inward.md §2A; S2 vendor docs say ratatui gives "little to no help in organizing large applications" |
+| B — Event glue (~50 _cmd_* handlers, reactives, tool-widget maps) | Native recode | 5 | Keep — this is Textual's core competency: workers, `exclusive=True`, `call_from_thread`, reactives | inward.md §2B; S1 workers guide; S8 ([CC] hard problems are orchestration/UX, not render speed) |
+| C — Model send path + envelope | Native recode | 5 | Keep — synchronous `rune_operator.send_task` in async worker with completion side-effects; the envelope shape is already the de-facto interop contract | inward.md §2C |
+| D — Subprocess/streaming | Native recode | 5 (shell) | Keep — JSONL streaming precedent already in-tree (`_cmd_pull` :3443-3517); it is the pattern for consuming recoded units, not a recode target | inward.md §2D; S6 JSON Lines spec |
+| Parse/render hot paths | Carve out to Rust unit | n/a | **No such hot path found.** If a future parsing need emerges (e.g. markdown in bubbles), carve it as a Rust native unit behind the adapter — not now. | inward.md §2A; S7 (push granular speed-sensitive work to hand-coded subcomponents) |
+| Whole TUI in Go/Rust | Recode | 1 | Rejected — 80+ first-party module coupling, framework-provided concurrency re-implemented by hand; Go additionally blocked by toolchain absence | inward.md §1, §3; S2, S3, S4, S5 |
+
+## ADAPTER SURFACE REQUIREMENTS (TUI as consumer — binds all other waves)
+
+1. **Single-invocation CLI statelessness.** Each call is a fresh process: `native_unit <op> [args]`. No daemon, no session state (matches `interop/rebase-proof` pattern; failure isolation for free).
+2. **Request/response JSON envelope.** On success, stdout's final line: `{"ok":true, …op-specific fields…}`. Generalizes the model-send envelope the TUI already consumes (`success/response/thinking/model/recall_count/degraded/tool_events`, rune_tui.py:3624ff). Recoded units returning `response`/`tool_events`/`degraded` shapes plug in with zero TUI changes.
+3. **Error semantics.** Failure = `{"ok":false,"error":"<machine-readable message>"}` on stdout with nonzero exit (proof contract uses exit 2); stderr reserved for human diagnostics. Success = exit 0 AND not timed out (`shared/native_units.py` line ~89) — this fixed metric is the contract's success definition.
+4. **Mandatory `--version` flag** on every native unit (already in proof contract) — lets the TUI's status bar and canary (`canary_tui_drift.py`) detect which units are live vs Python-fallback.
+5. **JSONL streaming mode for long ops.** One JSON object per line, `{"ok":true,"event":…}` progress objects, terminal sentinel = final envelope line. Consumed exactly like `_cmd_pull` (:3443-3517): per-line `json.loads` + `call_from_thread`. **Contract gap to fix:** `native_units.py` currently parses only the LAST stdout line — it must gain a streaming reader that yields per-line events and validates the terminal envelope.
+6. **Timeout budget per call** (`timeout_s=10.0` default in `native_units.py`); long ops must use streaming mode so partial progress is visible rather than blocked. `timed_out` is surfaced in `NativeResult` so the TUI can degrade gracefully (`degraded` list in the envelope).
+7. **Stable ids for update-in-place.** Streamed events referencing UI objects must carry the TUI's keys — `(channel, call_id)` for tool widgets (:3676), stable object ids for WorkPane `_entries` (:1239). Envelope fields that map to these keys must be preserved verbatim by recoded units.
+8. **Std-only constraint** for proof-phase units (no runtime deps), matching `interop/rebase-proof/src/main.rs`; relx it per-unit later only with justification.
+
+## Kill tests
+
+- **Stay-Python (shell):** killed if (a) UI-thread stalls >16ms are measured during heavy event bursts, or (b) worker↔subprocess IPC latency dominates message round-trip. Measure with Textual pilot + timing around `run_worker`/`call_from_thread`. Current evidence says neither is plausible (no render hot loop; the 120ms 21-step pipeline was already removed, `_run_warm_router` :3575 is a no-op).
+- **Native recode (Rust):** killed if the adapter must expose >~15 first-party modules to satisfy the TUI — the count today is ~80, so it is killed now.
+- **Native recode (Go):** additionally killed by toolchain absence (`command -v go` empty) — cannot even build proof units locally.
+
+## Evidence sufficiency
+
+Sufficient for the verdict: full inward read of all 5 TUI files with line refs; 8 live-fetched external sources (≥2 per major claim — stay-Python: S1/S2/S7/S8 with countervailing S3/S4/S5; streaming adapter: S6 + in-tree precedent; toolchain: local verification). Gaps: no runtime profiling (kill test (a)/(b) unmeasured — but no mechanism exists for the stall to occur); Textual FAQ timed out and was replaced by the workers guide + two additional sources.
+
+## Feasibility
+
+Adapter-only path is feasible now: proof contract exists and builds (Rust 1.98.1, std-only), TUI already has both request/response (`send_task`) and streaming (`_cmd_pull`) consumption patterns. Remaining engineering: streaming reader in `native_units.py` (gap #5) — small, testable, non-breaking.

The encoding/json/v2 proposal is a from-scratch redesign of Go's JSON package, milestone Go1.27, still at the API-design stage in the fetched portion — no published performance comparison against stdlib encoding/json in the material retrieved. Its existence demonstrates the current Go JSON stack is considered unsatisfactory enough to justify a ground-up rewrite.","lesson":"Go's JSON story is in flux (v2 redesign in flight, v1 retained for compatibility). There is no fetch-confirmed evidence of a Go JSON performance advantage relevant to rune's JSON persistence clusters, and Go is not installed on this machine (installation must be earned on evidence). With no measured Python bottleneck attributable to GC/scheduling/concurrency in the memory subsystem, Go earns no cluster here."}]}
