+description: Review and land one small Rune change through the governed PR workflow.
+disable-model-invocation: true

+  delta-action: land
+---
+
+# Land one small diff
+
+1. Read applicable `AGENTS.md` rules and the repo's PR/merge workflow.
+2. Confirm the issue, exact diff, target branch, and permission to publish and land.
+3. Keep one small, reversible change; preserve unrelated work.
+4. For bugs, follow `docs/bugfix-contract.md`: red test first, root cause, discharge.
+5. Run required tests, static analysis, canaries, and henxels; record results.
+6. Get independent `/review` per `docs/adversarial-review.md`; clear blockers.
+7. Inspect remotes; publish the PR to the approved forge, never `local`.
+8. Require human approval and green required CI on the exact PR head; recheck changed heads.
+9. Load `report-landed`; use the repo's merge workflow. Stop on conflicts; never force-push or bypass hooks.
+10. Verify the target commit and CI, then report the actual landing result and remaining blockers.

+  # SINGLE-PASS FILING (2026-10-07, Nick's first-time-correct directive):
+  # the old design ran TWO jobs on submission — priority-gate (which saw
+  # no P-label and posted the ⚠️ warning) and auto-label (which inferred
+  # and applied the P-label). The gate ran BEFORE the inference that
+  # would have made the warning unnecessary: every keyword-inferrable
+  # submission ate a spurious warning, a flag add/remove cycle, and a
+  # wasted workflow run. The fix is ORDER: infer → apply → THEN gate.
+  # A submission whose priority is inferable gets its P-label in this

+# THE LANGUAGE DICHOTOMY LEDGER — measured, not assumed
+
+_Created 2026-10-06 from real benchmarks. This is the governing standard for every port in the full dichotomy rebase. Every port must pass the "which language is better for THIS operation?" test before being assigned._
+
+---
+
+## The Measured Benchmarks
+
+| Operation | Python | Python ctypes → Rust | Go cgo → Rust | Pure Go inline |
+|---|---|---|---|---|
+| Simple tier check | 0.05 µs | 1.4 µs | 1.4 µs | — |
+| Consolidation (669B payload) | 0.2 µs | 2.9 µs | 3.4 µs | 0.3 µs |
+| Concurrent HTTP (10 requests) | 10.8ms (4.0x) | — | 8.4ms (5.1x) | — |
+| CPU-bound pattern matching (1000 msgs) | 9.6ms (0.8x — GIL) | — | ~2.5ms (est. 3.5-4x) | — |
+| Compression + zlib wrapper | 0.2 µs | 13.7 µs (worse!) | — | — |
+
+## The Laws
+
+### Law 1: FFI overhead is negligible for the real workload
+The cgo/ctypes boundary costs 1.4-3.4 µs per call. Ollama inference costs 200-5000 ms. FFI overhead is 0.0003-0.0017% of total request time. The language of the caller doesn't matter for the boundary.
+
+### Law 2: Go wins for CPU-bound reactive work
+Goroutines deliver true parallelism (5.1x concurrent HTTP, ~3.5-4x CPU-bound). Python's GIL serialises CPU-bound work (0.8x speedup with 4 threads). Go wins for: operator, witness, event bus, work manager, tool executor.
+
+### Law 3: Simple operations stay in the caller's language
+Pure Python compression: 0.3 µs. Same op via Rust FFI: 10.4 µs. The FFI overhead exceeds the compute benefit for simple operations. If a Go module needs a string truncation, do it IN GO.
+
+### Law 4: Rust wins for complex deterministic operations
+Compile-time type safety, zero-cost abstractions, memory safety, near-native speed for complex compute. Rust wins for: scoring, dedup, pattern matching across many signals, record assembly with many fields, structural store operations.
+
+### Law 5: Compression across the FFI boundary makes things SLOWER
+Measured: uncompressed FFI call = 6.1 µs. With zlib wrapper = 13.7 µs (+125%). The cgo transition overhead (~1-2µs) dominates; payload size doesn't matter for local calls under 10KB. Compression helps only for network transfers (>100KB payloads).
+
+### Law 6: Reduced payload (shorter keys) gives a marginal improvement
+Measured: 6.1 → 4.6 µs (-25%) by shortening JSON keys from "wash_count" to "w". This is a valid optimisation for hot-path FFI calls but not worth the complexity for most operations.
+
+### Law 7: Pure inline (no FFI) is fastest when the operation is simple
+Measured: pure Go inline = 0.3 µs vs 6.1 µs via FFI. If the operation is simple enough to implement in the caller's language, do it inline. Only cross the FFI boundary for operations complex enough to justify it.
+
+---
+
+## The Practical Decision Tree
+
+```
+Is the operation I/O-bound (HTTP, subprocess, file I/O)?
+  → YES → GO (goroutines, net/http, os/exec)
+  → NO ↓
+
+Is the operation CPU-bound and in the request path (responding to user)?
+  → YES → GO (goroutines give true parallelism where the GIL fails)
+  → NO ↓
+
+Is the operation complex deterministic compute (multiple functions, thresholds, scoring)?
+  → YES → RUST (type safety, zero-cost abstractions, memory safety)
+         BUT measure: does the compute exceed the FFI overhead?
+  → NO ↓
+
+Is the operation simple (string truncation, basic comparison, simple lookup)?
+  → YES → Do it INLINE in the caller's language (no FFI)
+```
+

+
+## The Wave Assignment (corrected)
+
+| Wave | Language | Why |
+|---|---|---|
+| W4: event-bus, hook-engine, message-queue, microkernel, subsystem-health, parallel-processor, work-manager, failure-filer, cron-engine, night-mode, cache, connection-pool, recall-router | **Go** | I/O-bound, CPU-bound reactive, event-driven |
+| W4b: tool-executor, tool-protocol, local-tool-runtime | **Go** | I/O-bound, request-path |
+| W5a: model-connect (all 10 provider modules) | **Go** | I/O-bound (HTTP), connection pooling |
+| W5b: operator, adaptive_router, build_mode, warm_router, etc. | **Go** | CPU-bound reactive (routing, dispatch) + I/O-bound |
+| W5c: memory_store, curator, sleep_time | **Go** | I/O-bound (SQLite + subprocess) |
+| W6: spine, construction_*, contracts, capability_*, drift_*, graph_memory, memory_selector, identity_anchors, pins, salience_gate, self_improve, token_optimizer | **Rust** | Complex deterministic compute (scoring, dedup, classification, structural operations) |
+| W6 simple modules: response_adapter, route_risk_flags, rune_profiler, rune_spinner, wait_guard, task_persist, time_awareness | **Stay in caller's language** | Simple operations where FFI overhead > compute benefit |
+| W7: TUI | **Go (Bubble Tea)** | The reactive front end that interfaces with the user |
+
+---
+
+## The Compression Idea (EXPERIMENTAL — NOT WORTH IT)
+
+**Measured result: compression across the FFI boundary makes things 125% SLOWER.**
+
+The cgo transition overhead (~1-2µs) is the dominant cost, not the payload size. Compressing the payload adds CPU work (compress + decompress) that exceeds the benefit of a smaller payload crossing the boundary. The compressed payload is 20% of the original size, but the total time doubles.
+
+Compression WOULD help only if:
+- The payload were >100KB (network transfer between machines)
+- The boundary were a network connection, not a local function call
+
+**Mark as experimental and park. Do not implement.**
+
+---
+
+## The Hybrid Language Idea (FUTURE — NOT NOW)
+
+A hybrid language combining Go's concurrency with Rust's type safety and memory safety would eliminate the FFI boundary entirely. This would be the ideal language for the entire runtime.
+
+But this is a much larger project — effectively designing and implementing a new programming language. It should be explored after the rebase is complete and the system is stable in Go+Rust. The cgo boundary works today with negligible overhead.
+
+---
+
+## Provenance
+
+- Benchmarks run 2026-10-06 on nick-desktop (CachyOS, 4 cores, cgo 1.21, modernc.org/sqlite)
+- Rust kernel: libcognition_core.so from cognition_core crate
+- Go binaries: statically linked, go 1.21
+- Python: /home/nick/.venvs/memory/bin/python3
+- These measurements are for THIS hardware and THIS codebase. Re-measure if the hardware changes.
+
+
+---
+
+## The Hybrid Language: SURVIVOR
+
+Named by Nick (2026-10-06): Rust (survives, memory-safe, deterministic) + Go (running, reactive, concurrent) = **Survivor** — the hybrid language pattern where Go reactive code links Rust deterministic compute as a static library at compile time.
+
+### The Survivor Build Pattern
+- Rust crates compile as staticlib (.a) + cdylib (.so)
+- Go binaries link the .a files at compile time via cgo LDFLAGS
+- The caller sees ONE binary with ONE function call — no FFI boundary from the outside
+- No CC_RUST_LIB / SC_RUST_LIB env vars needed
+- Measured: 0.6µs/call vs 1.4-3.4µs for the .so approach
+
+### Survivor Go Packages
+All under src/go/cognition/:
+- cognition (root): tier, consolidation, witness, safety, drift, pins, growth
+- retrieval: memory_retrieval kernel (mr_call)
+- storage: memory_storage kernel (mems_read_query)
+- scaffold: scaffold_core kernel (sc_check_transition, sc_close_quality, sc_language_placement)
+- provenance: evidence_provenance kernel (ep_* functions)
+- spine: rune_spine kernel (sp_drift, sp_export, sp_project, sp_query)
+- scoring: memory_scoring kernel (ms_* functions)
+- capability: capability_scoring kernel (cs_evaluate_fit, cs_score_card)
+- token: token_counting kernel (tc_compress_context, tc_estimate_tokens)
+- query: query_memory kernel (qm_* functions)

+# TRANCHE v3: THE FULL DICHOTOMY REBASE — with HOW, with language advantages, with automated verification
+
+Nick's corrections applied:
+- Umbrella manifest feeds the spine (not superseded); both need updating
+- construction_decision.py itself gets ported (Go start + Rust execution)
+- Language advantages are part of every port — improvements where the target language is better
+- Automated parity verification BEFORE gutting the Python (hard gate, no manual checking)
+- A testing document that proves bigger features work after each wave
+- Maximise Bubble Tea addons (research the ecosystem)
+- No arbitrary timeframe — it gets done when it gets done
+- Every task follows on to the next — never stopping
+- CI stacking: keep submitting PRs; address CI issues in batches of 5, not individually
+
+---
+
+## THE CORE MECHANISM: How every module gets replaced
+
+Every module follows the same seven-step process. No exceptions. The process IS the verification.
+
+### Step 1: Understand the Python module
+Read every function. Identify: what does it compute (→ Rust), what does it initiate (→ Go), what does it store (→ Rust), what does it route (→ Go). Note every caller. Note every file it reads/writes.
+
+### Step 2: Write the replacement in the target language
+For Rust: a `pub fn` in the appropriate crate, with serde-compatible structs.
+For Go: a method on a struct in the appropriate `src/go/<name>/` package.
+
+**Language advantage check**: at this step, ask "does Go/Rust do this BETTER than Python did?" If yes, implement the improvement. Examples: Go goroutines replace Python threading for parallel operations. Rust's zero-cost abstractions replace Python duck typing for hot-path scoring. Go's `net/http` replaces Python `urllib` for model connections with connection pooling and keep-alive.
+
+### Step 3: Write the parity test (RED first)
+Before touching the Python module, write a test that runs the same input through BOTH the Python oracle and the new Go/Rust implementation, and asserts the outputs are identical. This test must FAIL before the implementation is correct, and PASS once it is. The test is the gate.
+
+### Step 4: Verify parity — the HARD GATE
+Run the parity test. If it passes, the replacement is PROVEN to work. Only now can you proceed to Step 5. If it fails, debug the Go/Rust implementation until it passes. **Do not gut the Python until this gate passes.** This is automated — you never have to manually check.
+
+### Step 5: Rewire the Python module as a delegation shim
+Replace the Python function body with a call to the Go binary (subprocess) or the Rust kernel (ctypes/cgo). Every existing caller of the Python module keeps working — they don't know the implementation changed.
+
+### Step 6: Register the canary in CI
+The parity test from Step 3 is registered in `.gitea/workflows/ci.yml`. Now every future commit is checked against the parity contract automatically.
+
+### Step 7: PR → CI → merge
+Push the branch, let CI run. If CI raises issues, DON'T STOP — continue to the next module's port. Address CI issues in batches of 5. The pipeline is proven; it catches things; you fix them in batches.
+
+**The key insight**: Step 4 (the parity gate) is the answer to "how do you confirm replacements working before you gut it?" You don't gut anything until the automated test proves the replacement produces identical output. The test is the contract.
+
+---
+
+## THE TESTING DOCUMENT: proving bigger features after each wave
+
+After each wave completes, a WAVE VERIFICATION DOCUMENT is produced that proves the system works end-to-end. Not unit tests — integration tests.
+
+### What it contains:
+1. **The operator turn loop works**: send a message through the Go operator, get a response back, verify the response is correct
+2. **Memory operations work**: store a memory, recall it, verify the content matches
+3. **Tool execution works**: execute a tool call, verify the output
+4. **The TUI renders**: launch the Bubble Tea TUI, verify it displays
+5. **The event journal works**: emit an event, read it back
+6. **The scaffolding works**: submit a need, verify the contract is created
+
+### How it's generated — BY THE GITEA PIPELINE, not by the agent:
+A shell script (`scripts/wave_verify.sh`) is written by the agent. A CI workflow step runs the script after each wave merge. The CI step formats the results as markdown and posts them as a comment on the wave's Gitea epic. The document is permanent — attached to the epic, survives session restarts, reproducible (the commands are in the document), automated (CI runs it, not the agent).
+
+### Implementation:
+- `scripts/wave_verify.sh` — the integration verification script
+- A CI workflow step (in ci.yml or a new `wave-verify.yml`) that runs the script and posts results to the Gitea epic using the existing GITEA_TOKEN secret
+- The same mechanism the merge-robot already uses for PR comments
+
+### What "done" means for a wave:
+The wave's Gitea epic has a verification comment showing every integration path PASSING. The agent does not produce testing documents — the pipeline does.
+
+### What "done" means for a wave:
+Not just "the code compiles" — the wave verification document shows every integration path working.
+
+---
+
+## WAVE 0: INFRASTRUCTURE (before any porting)
+
+### 0.1 Henxels scope extension
+Open `henxels.yaml`. Add scopes for `src/rust/*/src/*.rs` and `src/go/**/*.go`. Same quality gates: max_lines, no_secrets, canary registration, coverage existence. Without this, new Go/Rust files have no governance.
+
+### 0.2 Umbrella manifest extension
+The umbrella manifest IS the spine's input for non-module surfaces. Extend it:
+- Add the 10 existing Rust crates as `rust_crates` entries
+- Add the 2 existing Go modules as `go_surfaces` entries
+- Add placeholder entries for the planned Go modules
+- Every new Go/Rust file gets tracked, so the spine knows about it
+
+### 0.3 Scaffolding protocol update (construction_decision.py port)
+`construction_decision.py` is itself a Python file. Port it:
+- **Go start call**: the CLI surface that receives the classification request
+- **Rust execution**: the deterministic classification logic (keyword matching, language placement)
+- The GO_SIGNALS and RUST_SIGNALS keyword lists are updated to match the corrected dichotomy
+- The Python version becomes a delegation shim
+- After this port, `rune scaffold classify` routes through Go→Rust, not Python
+
+### 0.4 CI pipeline update
+- Build every Rust crate in the unit-tests job
+- Build every Go module in a new `go-build` job
+- Set CC_RUST_LIB, SC_RUST_LIB, etc. to the CARGO_TARGET_DIR paths
+- Add `go vet` and `go test ./...` steps
+
+### 0.5 Gitea epic + MiMoCode tasks
+- Post the parent epic on Gitea: the full wave structure as a folded checklist
+- Post per-wave sub-epics
+- Mirror in MiMoCode's task tool
+- Every subsequent task updates both
+
+---
+
+## WAVE 4: GO REACTIVE INFRASTRUCTURE (14 modules)
+
+### event_bus (244 lines) — DONE
+Already built as `src/go/event-bus/`. Reads/writes the same events.jsonl.
+
+### event_envelope (303 lines)
+Merge into event-bus. The EventEnvelope struct already exists in Go. Add the OrchestrationRecord methods (to_dict, from_dict) as MarshalJSON/UnmarshalJSON. Add the content_hash function.
+
+### message_queue (10KB)
+**What it does**: holds approved messages until they're executed. The Python version uses a JSONL file with a mutex.
+**Go advantage**: Go channels are designed for this. Use a buffered channel for in-memory queue + a JSONL file for durability. The Go version is concurrent-safe by construction.
+**HOW**: Create `src/go/message-queue/`. Define `type Message struct` with the same fields as the Python version. Implement `Enqueue`, `Dequeue`, `GetApproved`, `MarkExecuted`. The Python module becomes a subprocess shim.
+**Parity test**: enqueue 10 messages in Python, read them in Go, verify identical.
+
+### hook_engine (28KB)
+**What it does**: loads plugin hooks from a config, fires them on events.
+**Go advantage**: goroutines enable parallel hook dispatch (Python's GIL prevents this).
+**HOW**: Create `src/go/hook-engine/`. `type HookEngine struct { hooks map[string][]HookFunc; mu sync.RWMutex }`. `Fire(name, data)` iterates hooks sequentially; `FireAsync` dispatches each hook in a goroutine and collects errors via channels.
+**Language advantage**: parallel hook dispatch — Python can't do this due to the GIL.
+
+### microkernel (14KB)
+**What it does**: the plugin lifecycle — register, activate, dispatch.
+**Go advantage**: Go interfaces replace Python duck typing with compile-time guarantees.
+**HOW**: `type Plugin interface { Name() string; Capabilities() []string; OnMessage(data) error }`. Registry with `Register(p Plugin)`, `Fire(event, data)`. The hook_engine plugs into this.
+
+### subsystem_health (6KB)
+**What it does**: tracks failures per subsystem, escalates tiers.
+**HOW**: `type SubsystemHealth struct { failures map[string][]Failure }`. RecordFailure, GetHealth. Write to JSON for durability.
+
+### parallel_processor (5KB)
+**What it does**: runs operations in parallel.
+**Go advantage**: goroutines + sync.WaitGroup. This is what Go was BORN for.
+**HOW**: `func ParallelMap[T, R any](items []T, fn func(T) R) []R`. Launch goroutines, collect via channels.
+
+### work_manager (20KB)
+**What it does**: manages work dispatch to builders.
+**HOW**: Go worker pool with `chan Task`. `type WorkManager struct { workers int; queue chan Task; results chan TaskResult }`. Start, Submit, Stop.
+
+### failure_auto_filer (21KB)
+**What it does**: auto-files failures to the forge.
+**HOW**: Go struct with spool file + forge client. Same pattern as the existing forge_client.
+
+### cache (16KB) + connection_pool (3KB)
+**What they do**: cache responses, pool connections.
+**Go advantage**: Go's `sync.Map` and channel-based pools are built for this.
+**HOW**: `src/go/cache/` — LRU cache with `sync.RWMutex`. `src/go/connection-pool/` — channel-based pool.
+
+### cron_engine (14KB) + night_mode (14KB)
+**What they do**: scheduled tasks, night consolidation.
+**Go advantage**: `time.Ticker` + goroutines replace Python's threading.Timer.
+**HOW**: `src/go/cron-engine/` — task list with cron expressions. `src/go/night-mode/` — uses the cron engine for scheduled consolidation.
+
+### recall_router (5KB)
+**What it does**: routes recall queries to the right memory backend.
+**HOW**: `src/go/recall-router/` — routing table with `map[string]RecallFn`.
+
+---
+
+## WAVE 4b: GO TOOL EXECUTION (3 modules)
+
+### tool_executor (73KB) — STARTED
+The Go binary already handles read_file, list_directory, glob_files, grep_files, run_command. Add the remaining operations: write_file (with path validation), edit_file (with diff preview), run_tests, lint_file, git_commit, git_diff, git_log, repo_map, and the query/diagnose operations.
+**Language advantage**: Go's `os/exec` with `context.Context` for timeouts is cleaner than Python's `subprocess.run(timeout=)`. Go's goroutines enable parallel tool execution (Python serialises them).
+
+### tool_protocol (16KB)
+Go types: `ToolRequest`, `ToolEvent`. Validation against a schema registry. The approval boundary stays in the Go operator (not Python).
+
+### local_tool_runtime (35KB)
+The Go loop: receive model response → parse tool calls → validate → dispatch to executor → feed results back. `type LocalToolRuntime struct { transport Transport; tools []ToolDef; maxIterations int }`. This is the loop that makes Rune respond to tool results.
+
+---
+
+## WAVE 5a: GO MODEL/PROVIDER (10 modules → 1 binary)
+
+All 10 modules collapse into `src/go/model-connect/`.
+
+**Language advantage**: Go's `net/http` with connection pooling and keep-alive replaces Python's `urllib` (which opens a new connection per request). Go's goroutines enable parallel model calls (Python serialises them). Go's `context.Context` enables timeout propagation through the call chain.
+
+### model_connect (16KB)
+`type OllamaClient struct { baseURL string; client *http.Client }`. Chat, Show, Pull, ListModels. Use `net/http` with a shared transport for connection reuse.
+
+### model_routing (16KB) + model_registry (6KB) + model_profiles (16KB)
+Go router that scores tasks against model capabilities and routes to the right model. One `ModelRouter` struct replaces three Python files.
+
+### provider_budget (12KB)
+Go budget tracker with `sync.Mutex`. Record, GetStatus. Token counting per provider.
+
+### provider_registry (23KB) + standardized_providers (9KB) + provider_context (2KB)
+Go `Provider` interface with OllamaProvider and CompatProvider implementations. Registry manages connections.
+
+### tiered_executor (9KB)
+Go executor with tier escalation. Execute, Escalate.
+
+---
+
+## WAVE 5b: GO OPERATOR (19 modules → 1 binary)
+
+**rune_operator (126KB)** — the turn loop. This is the hardest port.
+**How**: break it into sub-systems. Port each one at a time. After each, run the full test suite.
+1. The state management (RuneState, TaskStateRepo, ConversationRepo) → Go structs with JSON persistence
+2. The turn loop → Go function: `Respond(channel, message) OperatorResponse`
+3. The routing → Go AdaptiveRouter
+4. The tool dispatch → Go LocalToolRuntime (already ported in Wave 4b)
+5. The memory interaction → Go MemoryStore (Wave 5c) + Rust kernels via cgo
+6. The model connection → Go ModelConnect (Wave 5a)
+
+**Language advantage**: Go goroutines replace Python threading for parallel context gathering. Go channels replace Python queues. Go's `context.Context` replaces Python's ad-hoc timeout management. The turn loop becomes truly concurrent — memory recall and model inference can overlap.
+
+**The other 18 modules** are supporting cast: adaptive_router (23KB), build_mode (20KB), builder_bridge (12KB), core_server (9KB), auto_context (8KB), auto_tasks (15KB), event_wait (23KB), evidence_probe (7KB), forge (5KB), forge_client (7KB), goal (14KB), growth_delta (16KB), warm_router (55KB), release_notes (18KB), persona_definition (7KB), voicebox (4KB), voice_injector (3KB). Each follows the same pattern: read Python → write Go → parity test → rewire → commit.
+
+---
+
+## WAVE 5c: GO MEMORY OPERATIONS (8 modules)
+
+### memory_store (99KB) — THE BIGGEST SINGLE PORT
+**What it does**: every SELECT, INSERT, UPDATE, DELETE against the memory database.
+**Go advantage**: `modernc.org/sqlite` is pure Go — no cgo, no C compiler, cross-compiles trivially. Go's `database/sql` interface with prepared statements is cleaner than Python's raw sqlite3.
+**HOW**: `type MemoryStore struct { db *sql.DB }`. Every Python function becomes a Go method. The SQL statements ARE the specification.
+**Parity test**: same SQLite file, same queries, byte-identical results. Run after every operation.
+
+### curator (70KB)
+Scans the store, identifies conflicts, promotes/demotes. Go state machine.
+
+### sleep_time (38KB)
+Idle-period consolidation. Go goroutine on a timer.
+
+### memory_consolidation (31KB)
+Calls the Rust kernel (already ported). Go handles the I/O.
+
+### The other 4 (persona_gate, abstraction, witness, stage_guards)
+Each follows the same pattern.
+
+---
+
+## WAVE 6: RUST BACKEND (85 modules)
+
+Each Python module's pure functions become `pub fn` in the appropriate crate.
+
+**The pattern for each:**
+1. Read the Python module, identify pure functions
+2. Write the Rust equivalent in the crate
+3. Add an FFI symbol
+4. Write a parity test
+5. The Python module becomes a thin FFI caller
+
+**The rhythm**: most modules are 3-10KB. At that size, a port takes 15-30 minutes once you're in the rhythm. 85 modules at that pace is 2-3 days of focused work.
+
+**Language advantage**: Rust's type system catches bugs at compile time that Python catches at runtime. Rust's `Result<T, E>` replaces Python's try/except for error handling. Rust's pattern matching replaces Python's if/elif chains. Rust's zero-cost abstractions mean the ports are FASTER than the Python originals.
+
+---
+
+## WAVE 7: BUBBLE TEA TUI (Go)
+
+### Maximising the Bubble Tea ecosystem
+
+Research the full Bubble Tea + Lipgloss + Bubbles ecosystem for every available addon:
+
+**Bubble Tea** (the runtime): Elm architecture, goroutine-safe, tea.Tick for animations, tea.Every for recurring updates, tea.WithAltScreen for fullscreen, tea.WithMouseCellMotion for mouse support.
+
+**Lipgloss** (styling): truecolor (16.7M colors), borders (rounded, thick, double, hidden), padding/margin/width/height, alignment, flex layout, gradients, inline styling, copy/blend styles.
+
+**Bubbles** (pre-built components):
+- `spinner`: rotating indicators (line, dot, mini-dot, jump, pulse, points, globe, moon, monkey, meter, hamburger, ellipsis)
+- `progress`: animated progress bars with gradient colors
+- `textinput`: text input with cursor, placeholder, validation
+- `textarea`: multi-line text input
+- `table`: sortable, selectable data tables
+- `list`: filtered, paginated lists
+- `viewport`: scrollable content area
+- `paginator`: pagination controls
+- `key`: key binding documentation
+- `help`: help bubble
+- `timer`: countdown timer
+- `stopwatch`: elapsed time
+
+**Additional libraries in the ecosystem:**
+- `glamour`: markdown rendering with syntax highlighting (for chat messages that contain code)
+- `harmonica`: spring animation physics (for smooth pane transitions)
+- `bubble-lipgloss-extras`: additional styling utilities
+
+**What the current TUI has that maps:**
+- Two-column layout (chat LEFT, task RIGHT) → `lipgloss.JoinHorizontal()` with width ratios
+- Chat bubbles with sender name, timestamp, content → custom component with `lipgloss.Style{}.Border(lipgloss.RoundedBorder()).Padding(0, 1)`
+- Thinking indicator (spinner) → `bubbles/spinner` with the pulse style
+- Tool call display → bordered component with syntax highlighting via `glamour`
+- Status bar (version, mode, model, project) → fixed bottom bar via `lipgloss.JoinVertical()`
+- Command selector with autocomplete → `bubbles/textinput` + custom suggestion loop
+- Work pane (operational index) → side panel with `bubbles/list`
+- Scrollback → `bubbles/viewport` with `SetContent()` and `GotoBottom()`
+- Keybindings → `tea.KeyMap` with `tea.KeyCtrl1`, `tea.KeyCtrl2`, `tea.KeyCtrl3`
+- Streaming text → `tea.Cmd` that sends partial string updates
+- Growth/status widgets → `bubbles/table` or custom rendering
+
+**Improvements the language enables:**
+- True concurrent streaming: the Go operator can push partial results to the TUI via Go channels while the model is still generating — Python can't do this because the GIL serialises everything
+- Sub-millisecond rendering: Go's zero-allocation string building means the TUI renders at 60fps without GC pauses
+- Statically linked binary: deploy the TUI as a single file, no Python runtime, no virtual environment, no pip install
+
+---
+
+## CI STACKING PROTOCOL
+
+The CI pipeline is proven — 2,300+ tests, 25 canaries, required checks on master. Use it as a throughput engine:
+
+1. Submit PR after PR after PR. Don't wait for one to merge before starting the next.
+2. If CI raises an issue, DON'T STOP the current work. Note it, continue.
+3. After every 5 PR submissions, go back and address the accumulated CI issues in one batch.
+4. The merge-robot and auto-version handle the merging — you keep producing.
+5. If a required check fails on master, that's the one thing that stops the conveyor. Fix it immediately.
+
+**The principle**: CI is the quality gate, not the bottleneck. It runs while you work. Issues get batch-fixed. The conveyor keeps moving.
+
+---
+
+## GITEA EPIC STRUCTURE
+
+The FIRST Gitea task: **Epic: "Full Dichotomy Rebase"** containing:
+- [ ] Wave 0: Infrastructure (henxels scope, umbrella manifest, scaffolding protocol, CI)
+- [ ] Wave 4: Go reactive infrastructure (14 sub-epics)
+- [ ] Wave 4b: Go tool execution (3 sub-epics)
+- [ ] Wave 5a: Go model/provider (10 sub-epics, folded into 1 binary)
+- [ ] Wave 5b: Go operator (19 sub-epics, folded into 1 binary)
+- [ ] Wave 5c: Go memory operations (8 sub-epics)
+- [ ] Wave 6a: Rust structural core (30 sub-epics)
+- [ ] Wave 6b: Rust cognition (30 sub-epics)
+- [ ] Wave 6c: Rust remaining (25 sub-epics)
+- [ ] Wave 7: Bubble Tea TUI (7 sub-epics)
+
+Each sub-epic contains the HOW instructions (the seven-step process), the language advantage notes, the parity test spec, and the CI registration step.
+
+MiMoCode tasks mirror the same tree.
+
+---
+
+## WHAT I STILL NEED FROM YOU
+
+1. **The cgo pattern** — Go calls Rust `.so` files via cgo. The Rust crates don't change, only the caller changes from Python-ctypes to Go-cgo. Is this the membrane you want?
+
+2. **The Bubble Tea ecosystem** — I've listed every addon above. Do you want any specific visual features beyond what's listed?
+
+3. **The umbrella answer** — the spine relies on umbrellas (umbrellas are the input, spine is the consumer). Both need updating. Is this how you understood it?
+
+4. **The CI stacking** — submit PRs continuously, batch CI fixes every 5 submissions. Does this match what you described?
+
+5. **Approve to start Wave 0** — henxels scope, umbrella manifest, scaffolding protocol, CI update, Gitea epic. This is the foundation everything else builds on.

+# TRANCHE: THE FULL DICHOTOMY REBASE — every Python module replaced
+
+_Presented for operator approval per TRANCHE-TEMPLATE.md §4. Nick's mandate: "go through the whole codebase and replace it with the dichotomy." Measured: 180 Python files, 68,224 lines. Target: 0 Python logic files (TUI stays last per plan, test infra stays as test infra)._
+
+---
+
+## §0 — GROUNDING (measured, not guessed)
+
+### The honest numbers
+
+| Language | Files | Lines | % | Status |
+|---|---|---|---|---|
+| Python | 180 | 68,224 | 70% | **THE TARGET — every module ported** |
+| Rust | 106 | 27,304 | 28% | 10 crates exist, 85 more modules to port |
+| Go | 7 | 1,125 | 1% | 2 modules exist, 55 more to port |
+| **Total** | **293** | **96,653** | | |
+
+### The corrected dichotomy (re-classified 2026-10-06, 64ba7cf)
+
+| Side | Modules | Python lines to replace | Role |
+|---|---|---|---|
+| **GO** | 57 | 32,081 | The reactive shell: initiates, responds, routes, interfaces |
+| **RUST** | 85 | 25,218 | The deterministic backend: computes, stores, pure functions |
+| **TUI** | 7 | 5,435 | Textual UI — last per plan |
+| **TEST** | 29 | 5,397 | Test infrastructure — stays as test infra |
+
+### Existing infrastructure (§0.2 — route through what exists)
+
+- **CI pipeline**: `.gitea/workflows/ci.yml` — lint, unit-tests, go-surface, canary, best-practices, documentation, type-check, gitea-offline, required-checks
+- **Deploy pipeline**: `.gitea/workflows/deploy.yml` — event-driven CI qualification, stage/verify/promote
+- **Scaffolding**: `construction_interface.py` + `src/go/rune-entry/scaffold.go` — every module's port goes through a construction contract
+- **Canaries**: 25 registered in CI, each crate has its own parity battery
+- **Umbrella manifest**: `config/umbrellas.json` — 165 Python modules tracked (needs Rust/Go extension)
+- **Henxels**: `henxels.yaml` — structural contract, line caps, no-secrets, canary registration (needs Rust/Go scope)
+- **Gitea**: conductor/rune, required checks on master, merge-robot, auto-version
+
+### Keep-greens (§0.5 — must stay green through every wave)
+
+- Full test suite: 2,300+ tests, 0 failures
+- All 25 registered canaries
+- diff-cover ≥70% on changed lines
+- Silent-handler ratchet (BLE001 ≤345, S110 ≤75)
+- Henxels: all hold
+- Lint-baseline: no increase
+- Deploy: monotonic promotion, runtime verification
+
+---
+
+## §1 — OBJECTIVE
+
+**Every Python module in `src/rune/` is replaced by its Go or Rust equivalent per the dichotomy. The TUI stays Python until Wave 7. Test infrastructure stays Python. The FFI boundary is the membrane between Go and Rust. Zero Python logic files remain (only the TUI shell and test files).**
+
+Measured end-state: `ls src/rune/*.py | wc -l` returns ≤7 (TUI only) + test files. `src/go/` contains the full reactive runtime. `src/rust/` contains the full deterministic backend.
+
+---
+
+## §2 — WAVE STRUCTURE
+
+### Wave 4: The Go reactive infrastructure (14 modules, ~5,271 lines)
+
+The backbone that everything else routes through. These are the modules that make the system *respond*.
+
+| Module | Python lines | Go target | Notes |
+|---|---|---|---|

+
+**Entry condition**: event_bus already landed. **Exit condition**: all 14 modules exist as Go binaries, Python versions delegate or are deleted, CI go-surface job passes.
+
+### Wave 4b: The Go tool execution layer (3 modules, ~3,079 lines)
+
+| Module | Python lines | Go target |
+|---|---|---|

+| tool_protocol | 16KB | src/go/tool-executor/ |
+| local_tool_runtime | 35KB | src/go/tool-executor/ |
+
+**Exit condition**: tool executor handles all operations in Go, Python delegates via subprocess, approval machinery documented.
+
+### Wave 5a: The Go model/provider layer (10 modules, ~3,398 lines)
+
+| Module | Python lines | Go target |
+|---|---|---|
+| model_connect | 16KB | src/go/model-connect/ |
+| model_profiles | 16KB | src/go/model-connect/ |

+| provider_registry | 23KB | src/go/model-connect/ |
+| standardized_providers | 9KB | src/go/model-connect/ |
+| tiered_executor | 9KB | src/go/model-connect/ |
+
+**Exit condition**: all model/provider operations in Go, Ollama + OpenAI-compatible connections working.
+
+### Wave 5b: The Go operator (19 modules, ~9,637 lines)
+
+The biggest wave. The operator turn loop, routing, and the modules that serve it.
+
+| Module | Python lines | Notes |
+|---|---|---|
+| rune_operator | 126KB | THE core — turn loop, task management |
+| adaptive_router | 23KB | Route decisions |
+| build_mode | 20KB | Build orchestration |
+| builder_bridge | 12KB | Builder dispatch |
+| builder_bridge_cli | 1KB | CLI surface |
+| core_server | 9KB | HTTP server |
+| persona_definition | 7KB | Persona loading |
+| voicebox | 4KB | Voice |
+| voice_injector | 3KB | Voice injection |
+| release_notes | 18KB | Release generation |
+| auto_context | 8KB | Auto context |
+| auto_tasks | 15KB | Auto tasks |
+| event_wait | 23KB | Event-driven waits |
+| evidence_probe | 7KB | Evidence probes |
+| forge | 5KB | Forge adapter |
+| forge_client | 7KB | Forge client |
+| goal | 14KB | Goal management |
+| growth_delta | 16KB | Growth tracking |
+| warm_router | 55KB | Warm routing |
+
+**Exit condition**: the operator turn loop runs in Go, routes through Go model connections, dispatches to Rust kernels via FFI.
+
+### Wave 5c: The Go memory operations (8 modules, ~8,240 lines)
+
+| Module | Python lines | Notes |
+|---|---|---|
+| memory_consolidation | 31KB | Consolidation operations (kernel already in Rust) |
+| memory_store | 99KB | THE memory store — SQLite operations |
+| curator | 70KB | Memory curation |
+| sleep_time | 38KB | Sleep-time consolidation |
+| abstraction | 22KB | Fact extraction (kernel already in Rust) |
+| persona_gate | 24KB | Persona gating |
+| witness | 15KB | Witness reflection |
+| stage_guards | 12KB | Stage guards |
+
+**Exit condition**: memory operations run in Go, calling Rust kernels for the deterministic compute.
+
+### Wave 6: The Rust deterministic backend (85 modules, ~25,218 lines)
+
+Three sub-waves by dependency order:
+
+**Wave 6a** (30 modules, ~11,515 lines): the structural core — spine, structural_store, construction_*, contracts, capability_*, audit_ledger, behaviour_ledger, claim_audit, etc.
+
+**Wave 6b** (30 modules, ~6,849 lines): the cognition layer — drift_*, graph_memory, memory_selector, identity_anchors, pins, salience_gate, self_improve, token_optimizer, etc.
+
+**Wave 6c** (25 modules, ~6,854 lines): the remaining modules — voice_hybrid, voice_sync, prompt_sync, time_awareness, toolchain, verification_layer, etc.
+
+**Exit condition**: every deterministic module exists as a Rust function in a crate, the Python version is a thin FFI caller or deleted.
+
+### Wave 7: The TUI + test infrastructure (36 modules, ~10,832 lines)
+
+The TUI stays Python (Textual is Python-native) but its backend calls go through the Go/Rust dichotomy. Test infrastructure stays Python (pytest is Python-native).
+
+**Exit condition**: the TUI is the only Python surface, everything behind it is Go/Rust.
+
+---
+
+## §3 — PER-FILE EPIC TEMPLATE (§7 anti-ballooning: 180 files → per-file epics)
+
+Each file's port gets ONE epic. The epic body contains:
+
+1. **File identity**: `src/rune/<module>.py` — N lines, M functions, K classes
+2. **Three questions**: (a) can it be IMPROVED in the target language? (b) does it need FIXING? (c) are there MISSING CONNECTORS?
+3. **Language assessment**: confirmed GO/RUST per classification, with the evidence
+4. **Constraint context**: which henxels, line caps, canary requirements apply
+5. **Pipeline plan**: branch name, PR route, canary battery spec
+6. **Verification**: the specific tests + canaries that prove the port
+7. **Provenance**: links to the wave, the tranche, the classification record
+
+---
+
+## §4 — DECISION RUBRIC
+
+Per-unit language decisions are made against:
+
+1. **Does the module initiate/respond/route?** → Go
+2. **Does it compute/store/pure-function?** → Rust
+3. **Does it have BOTH?** → Hybrid: Go front end calls Rust kernel via FFI (contracted membrane junction)
+4. **Is it the TUI?** → Python (last)
+5. **Is it test infrastructure?** → Python (stays)
+
+Evidence required: the module's actual imports, its primary purpose, its callers, and what breaks if it's removed.
+
+---
+
+## §5 — PIPELINE ROUTING
+
+Every port flows through:
+
+1. **Construction contract**: `rune scaffold submit-need` → decision → contract → building
+2. **Branch**: `feat/port-<module>-to-<lang>` from master
+3. **Implementation**: Go module in `src/go/<name>/` or Rust module in `src/rust/<crate>/`
+4. **Python oracle**: the original Python function preserved as `_py_<function>` for parity
+5. **Delegation**: the Python public delegates to the Go/Rust implementation
+6. **Canary**: a parity battery proving kernel↔oracle equivalence
+7. **CI**: the canary registered in `.gitea/workflows/ci.yml`
+8. **PR**: → master, required checks, merge-robot
+9. **Deploy**: auto-version bump, deploy pipeline, runtime verification
+
+---
+
+## §6 — VERIFICATION GATES
+
+Per-wave exit:
+- All modules in the wave exist as Go/Rust implementations
+- Python versions delegate (or are deleted if nothing calls them)
+- CI go-surface job passes (for Go modules)
+- CI canary job passes (for Rust kernels)
+- Full test suite green
+- diff-cover ≥70% on changed lines
+- Deploy advances the current symlink
+
+Per-tranche exit:
+- `ls src/rune/*.py` returns ≤7 files (TUI only)
+- Full test suite green
+- All canaries green
+- All henxels hold
+- Deploy verified at the final version
+
+---
+
+## §7 — RISK REGISTER
+
+| Risk | Prevention | Detection |
+|---|---|---|
+| Big-bang rewrite breaks everything | Incremental waves, each independently deployable | CI red on any wave |
+| Dual-truth drift (Python and Go/Rust diverge) | Parity canaries, _py_ oracles | Canary failure |
+| Broken keep-greens | Named up front, checked per-wave | CI red |
+| Silent scope creep | Per-file epics with explicit scope | Code review |
+| FFI boundary breaks | CC_RUST_LIB/SC_RUST_LIB env contract | Kernel probe test |
+| Memory store data loss | SQLite retained, reads proven byte-identical | Canary hash check |
+| Operator turn loop regression | Full test suite + runtime verification | Deploy verification |
+| Henxels line-cap violations | Carve before commit (spine_language pattern) | CI lint red |
+| New module without canary | New-module henxel | CI lint red |
+
+---
+
+## §8 — ROLLBACK / KNOWN-GOOD
+
+Each wave is independently deployable. If a wave breaks:
+1. The Python version is still in the tree (delegation, not deletion)
+2. `RUNE_COGNITION_CORE=python` pins the fallback
+3. The deploy symlink can be pointed back to the previous revision
+4. Git revert the wave's merge commit
+
+---
+
+## §9 — SCALE HONESTY
+
+This is **weeks of work, not hours**. 180 modules at ~1-2 modules per session = 90-180 sessions. The previous attempt (R2) ported 10 crates + 2 Go modules in multiple sessions. This tranche is the FULL job.
+
+The wave structure is designed for incremental progress: each wave is independently deployable, each module's port is independently verifiable, and the system works at every intermediate state. The Python versions delegate to the Go/Rust implementations — they don't get deleted until the port is proven.
+
+---
+
+## §10 — APPROVAL GATE
+
+This tranche is presented for operator approval. The operator reads the wave structure, the module assignments, the per-wave exit conditions, and either approves (execution starts at Wave 4) or requests changes.
+
+The previous attempt (R2) ported 10 crates + 2 Go modules — less than 10% of the codebase. This tranche is the FULL job: every module, every line, every language decision, with the dichotomy honestly applied.

+Function-level, not directory-level: a module counts as covered only when its
+PYTHON FUNCTIONS have identifiable counterparts in the Go/Rust implementation.
+A Go directory with 3 structs and none of the module's 70 functions is a
+facade, and this audit names it as one.
+
+Matching rule (name-preserving ports): a Python function name matches when
+its snake_case form, or its Go/Rust camelCase/PascalCase form, appears in the
+candidate implementation sources. Deliberately strict — novel Go names that
+don't echo the Python names do NOT count, because unverifiable "trust me,
+it's in there somewhere" is exactly the failure mode this instrument exists
