+# FACTORY VERIFICATION LADDER (binding, 2026-10-11)
+
+Every dichotomy port landing MUST pass all six layers before it counts as
+FULL. The ladder is the anti-slop core: generation is cheap, verification
+is what transfers reliability.
+
+## The six layers (in order)
+
+1. **Existence.** The commit SHA is on gitea/master; the diff touches the
+   files claimed. Catches fabrication.
+2. **Green in MY checkout.** Battery re-run fresh (Go tests / cargo test /
+   clippy / vet / gofmt). Must pass on the reviewer's machine, not just
+   the agent's. Catches environment artifacts.
+3. **Truth consumed, not self-generated.** The test reads the frozen truth
+   file. Then: regenerate truth from the live oracle independently and
+   byte-compare against the frozen file. Catches self-consistent misreads
+   (agent + battery agree, oracle disagrees) — the most dangerous failure.
+4. **Live parity re-run.** Port vs live oracle on truth inputs, 100%.
+   Catches stale-library and PYTHONPATH artifacts.
+5. **Python surface intact.** Module's existing suite green, both with
+   delegation live and oracle pinned (RUNE_*_CORE=python). Catches wiring
+   regressions and collateral damage.
+6. **Phase B real (v2).** Battery green after the improvement commit; the
+   improvements are genuine language advantages (enums, exhaustive match,
+   iterators, Result, zero-copy, lifetimes / goroutines, interfaces,
+   compile-time safety), not cosmetic churn. Read the diff.
+
+## Limits of the ladder
+
+Parity proves faithful translation, NOT original correctness. Oracle bugs
+need architectural judgment — escalate per the bug policy (rare, to #2479,
+work keeps flowing).
+
+## Throughput law
+
+Verification scales linearly with landings; reviewer throughput is the
+gate. Spawn rate must not exceed verification rate. Backlog of unverified
+landings is a stop-spawning signal, not a queue to admire.
+
+## Factory workflow law (continuous-flow, 2026-10-11)
+
+**On every agent completion notification, the coordinator does exactly three
+things, in order:** (1) verify the landing through the six+1 layer ladder,
+(2) update the count, (3) run `scripts/factory_spawn_gate.sh` — if ALLOW,
+spawn the next queued module into a fresh worktree.
+
+**Wave-thinking is the anti-pattern.** Waves create dead time: 11 agents
+porting while the 12th lands means 11 worktrees idle until the wave drains.
+Continuous flow keeps every worktree occupied, the verification gate never
+starves, and the spawn gate (`factory_spawn_gate.sh`) enforces the limits
+deterministically — agent count and verification backlog never rely on
+coordinator cognition.
+
+**The spawn gate answers ONE question:** may a new agent spawn now?
+Limits: max 12 active, max 3 unverified landings. The gate is law — the
+coordinator does not override it from feel.
+
+## NO-REPORT LAW (operational, 2026-10-12)
+
+The coordinator does NOT report landings, counts, or progress to Nick between
+waves. Reporting interrupts autonomy — the coordinator's job is to keep the
+factory running, not narrate it.
+
+**What replaces reporting:**
+- The audit instrument (`dichotomy_audit.py`) IS the progress report — Nick
+  reads it when he wants to know.
+- Session notes capture the full state for checkpoint continuity.
+- The only exception: a genuine architectural blocker that needs Nick's
+  decision (per the bug policy), posted to #2479, not surfaced in chat.
+
+**Verification and spawning continue silently.** The coordinator verifies
+each landing, updates the count internally, spawns the next module — all
+without producing output for Nick. This is the no-stop law applied to
+reporting: stopping to report IS stopping.
+
+## DUPLICATE-SPAWN LAW (2026-10-12)
+
+Before spawning an agent for module X:
+1. Check `docs/factory-claims.json` — if the module is in `landed` or `in_flight`, SKIP.
+2. Check `git log gitea/master --oneline -- <module_paths>` — if a dichotomy wave commit exists, SKIP.
+3. Add the module to `in_flight` in `factory-claims.json` BEFORE spawning.
+4. On landing: move from `in_flight` to `landed`.
+5. On abort: move from `in_flight` back to the queue.
+
+general-47 wasted 1.5h porting behaviour_ledger because general-46 landed it
+first and the spawn dispatch didn't check. This law prevents that.

+## SIZE-ADAPTIVE BATCHING (2026-10-12)
+
+The factory auto-scales agent assignment based on module size:
+
+| Module size | Agent assignment | Rationale |
+|---|---|---|
+| < 100 lines | 3-5 per agent (batch) | Setup cost amortizes; context fits |
+| 100-300 lines | 1-2 per agent | Moderate context; maybe 2 small + 1 medium |
+| 300-800 lines | 1 dedicated agent | Full context needed per module |
+| 800-1500 lines | 1 dedicated agent, possibly split | Large oracle; agent may need 2 sessions |
+| > 1500 lines | Coordinator ports directly (Rune) | Load-bearing; agent context can't hold the full oracle reliably |
+
+The batch prompt template includes a "read the module, decide if it fits, skip if it doesn't" instruction so the agent self-reports when a module is too large for the batch context.

+"""freeze_truth.py — shared truth-freezing harness for dichotomy ports.
+
+ONE law for every factory agent freezing oracle truth. Replaces per-agent
+reinvention of: pinned clock, deep-copy inputs, envelope shape, verbatim
+embedding. Same conventions as the port laws in the verification ladder:
+  * RUNE_*_CORE=python pinned during capture (oracle runs pure Python)
+  * `now` is always an argument (no-clock law) — callers pass ISO-8601
+  * inputs are deep-copied before every call (no live-reference aliasing)
+  * truth is JSON: [{"fn", "args", "kwargs", "expected"}...] — embedded
+    VERBATIM into the battery (never hand-transcribed)
+
+Usage (as a library, from a generator script):
+    from freeze_truth import freeze
+    cases = freeze("module_name", [
+        ("fn_name", (arg1, arg2), {"kw": 1}),
+        ("other_fn", (deep_copied_obj,), {}),
+    ], oracle_module="rune.module_name")
+
+Usage (as a script, to re-verify a frozen file against the live oracle):
+    python3 scripts/freeze_truth.py --verify src/rust/<crate>/frozen_truth.json \
+        --module rune.<module>
+
+The generator script (per module) imports this, builds the case list

+(kernel_input, expected_kernel_output) pairs into
+src/rust/drift_resume/src/frozen_dr_resume_truth.json.

+Boundary law: the observer callable (reconcile) and the FILESYSTEM walk
+(detect_structural_drift: exists + the moved-twin rglob) stay in the
+Python facade — the kernel is a pure function of their results. Kernel

+"""gen_project_registry_truth.py — freeze/replay parity truth for
+project_registry (dichotomy wave, #2479 tranche).
+
+Freeze mode (default): exercises EVERY public function of the LIVE Python
+oracle (src/rune/project_registry.py) across every branch and records
+(kernel_input, expected_kernel_output) pairs into
+src/rust/project_registry/src/frozen_pr_truth.json.
+
+Replay mode (--replay): re-runs the SAME scenarios with the Rust core
+delegation active and asserts both kernel-level (loader direct) and
+facade-level (oracle methods delegate) parity against the frozen file.
+
+Poisoned-truth law: freeze pins RUNE_PR_CORE=python BEFORE any import (a
+no-op pre-port, load-bearing post-port — the facade must never delegate
+into the kernel while truth is being frozen).
+
+No-clock law: the wall clock is frozen by patching the `time` symbol in
+project_registry, so every kernel payload carries its own `now` and
+replay is deterministic regardless of run date.
+
+Boundary law: the registry FILE IO (_load hit branch, save) stays in the
+Python facade — the kernel is a pure function of the loaded doc. The
+`load` and `save` truth groups are facade-only (no kernel symbol) and
+are skipped by the kernel-level replay pass.

+"""gen_recall_uplift_truth.py — freeze the recall_uplift parity oracle
+(dichotomy wave #2479 tranche).
+
+Generator law: RUNE_RU_CORE=python pinned, inputs deep-copied, every
+expand() branch exercised: empty query, expansion-map matching (k in q /
+q in k / k in t), store pass (LIKE match, LIMIT 32, distinct-doc
+co-occurrence, df<5% distinctive filter, 24-term cap), and the best-effort
+degrade (no store / sqlite error → map terms only).
+
+PORTABLE LAW: CPython set iteration is hash-random, and the oracle's
+candidate sort is stable over dict insertion order — so the frozen corpus
+gives every co-occurring candidate word a DISTINCT doc count (ties would
+make even Python-vs-Python output order nondeterministic).
+
+Output: src/rust/recall_uplift/frozen_ru_truth.json — replayed VERBATIM by
+the crate's cfg(test) battery.
