refactor(construction_commands): Phase B language-advantage pass — dichotomy wave

Typed CommandType/Op/PhaseClass lattices replace the string-arm chains: parse IS the unknown-command refusal surface, the (command, phase-class) tuple match in _validate is exhaustive, and command_to_operation maps through to_op. Behavior byte-identical to the Phase A parity port — frozen battery the referee, zero truth changes (sha256 ba9fb44d pre == post; replay 54/54; pytest 12/12 both pins; clippy -D warnings clean).
feat(construction_commands): port to FULL Rust — dichotomy wave

+
+The adaptive_router precedent: preflight returns a BuilderCapsule the
+freeze harness cannot JSON-serialize and stamps generated_at from an
+in-function datetime import, and _default_selector/_get_selector return
+live selector instances. Those surfaces are pinned HERE, by driving the
+live Python oracle and the Go binary across every branch with full
+to_dict + to_markdown comparison (generated_at normalized — both sides
+render the same wall-clock shape, the value is the caller's).
+
+Case families:
+  * route branches: LOCAL_FIX defect, STANDARD_CHANGE, RESEARCHED_CHANGE
+    floor (incl. the doubled floor-prefix quirk), MEASUREMENT_REQUIRED
+    language, inspection-verb neutral class, unicode, >200-rune titles.
+  * construction branches: committed fixtures (active / quiet / terminal)
+    AND the DEFAULT store branch (both sides read the real repo store
+    live — equal at the same moment regardless of its content).
+  * memory: degrade-safe abstention under an isolated HOME (both sides).
+  * selector observables: lazy singleton identity + non-None default
+    selector (Python-observable contract; Go's is compile-time).

+surface (dichotomy wave #2479 gap close).
+
+Corpus: the frozen envelope (frozen_cm_truth.json — 36 classify cases, 3
+to_dict receiver cases, 5 from_dict projections, 3 error shapes) replayed
+against BOTH sides live, plus the invalid-override ValueError crash-parity
+case (un-freezable through the shared harness; compared here).
+
+The oracle side runs in a SUBPROCESS with PYTHONHASHSEED=0 — the oracle's
+lexicons are Python sets, so multi-hit evidence order is hash-random per
+process and the deterministic contract is the seed-0 order the Rust
+arrays reproduce (memory_consolidation precedent; the truth generator
+re-execs itself under the same seed).
+
+Usage: python3 scripts/check_construction_mode_parity.py

+"""check_drift_compression_parity.py — live parity for the drift_compression
+gap-close port (dichotomy wave, #2479 tranche).
+
+Three live layers over the FROZEN truth
+(src/rust/memory_scoring/src/frozen_dcomp_truth.json, 65 cases, frozen via
+scripts/gen_drift_compression_truth.py against the pure _py_* oracle):
+
+  1. facade PINNED  — RUNE_MEMORY_CORE=python: the public fns run the
+     load-bearing Python fallback against the frozen expectations.
+  2. facade LIVE    — delegation on (the built memory_scoring .so through
+     ms_loader): the same public fns against the same expectations.
+  3. KERNEL         — ms_loader.* called directly (the FFI envelope path).
+
+Plus two end-to-end seams the frozen file cannot carry (a sqlite
+connection is not JSON-freezable):
+  4. db-level get_compression_stats: an in-memory entries table seeded with
+     active/inactive rows, SQL nulls and mixed rock statuses — pinned vs
+     live vs the _py math, all three must agree (pins the status='active'
+     filter and the None coercion of SQL nulls).
+  5. FUZZ (seed 2479): deterministic random entries/rows/texts (unicode
+     included) — pinned facade vs live facade vs kernel, plus the stats
+     row-reduction, N rounds each.
+
+Comparison law: structural == (dict/list equality). The one documented
+representation quirk: integral FLOATS crossing the FFI render int-shaped
+(savings_pct 50.0 from the oracle, 50 from the envelope) — == treats them
+equal, which is exactly how the oracle's own consumers read the dict;
+byte-shape parity for the stats dict is pinned by the Rust battery's
+frozen replay instead.
+
+Exit 0 iff every layer is 100%.

+"""check_event_bus_parity.py — live oracle-vs-Go parity sweep for the
+event_bus gap closure (#2479, contract factory-gap-eb).
+
+The frozen envelope (truth_bus.json, 61 cases) pins the surface byte-
+identically. THIS script drives the LIVE Python oracle (under the
+scripts/eb_freeze_seams rig: frozen clock + deterministic uuid counter +
+hermetic journal sandbox) and the Go binary (`op` mode, EE_FROZEN_NOW +
+per-op reset + the same sandbox normalization envs) across the same
+branches plus live extras, comparing the PYTHON-json byte form of every
+result:
+
+  * store_path — the env-derivation matrix via SUBPROCESSES (sandbox/,
+    empty/, RUNE_HOME/, ~/ expansion, $HOME expansion, unset default),
+    normalized to EB_SANDBOX / EB_HOME / REPO_ROOT placeholders.
+  * event_types — the vocabulary table in definition order.
+  * content_hash — any-shape payloads (sort_keys, ensure_ascii).
+  * emit/emit_line — envelope build + durable append + journal LINE bytes,
+    incl. the loud ValueError branches (dict/int/NoneType/float/bool/list).
+  * log — filter + [-limit:] truncation matrix (0 → ALL, -N → front drop),
+    the typed corrupt-file raise, and the cross-writer probe (oracle
+    writes, Go replays the SAME file via the "replay" op).
+  * stats — (total, by_type) first-occurrence order.
+  * handle_hook — prefix, payload shaping (raw[:200], str(v)[:200] with
+    repr forms + truncation, falsy data), journal after each hook.
+  * main — captured CLI stdout + exit (emit/log/stats/hook, --json modes).
+
+Usage: PYTHONPATH=scripts/eb_freeze_seams:src python3 scripts/check_event_bus_parity.py
+  [--bin src/go/event-bus/event-bus]
+Exit 0 on 100% parity (incl. the negative control detecting perturbation),
+1 with the first divergences, 2 if the negative control fails to detect.

+  * EventEnvelope.create — canonical bridge: CHANNELS prior vocabulary,
+    channel/source/unknown fallback chain, canonical asdict nesting.
+  * to_dict — 9-key legacy dict with insertion-ordered payloads.

+  2. FUZZ — 40 seeded optimizer instances (seed 2479), each running a
+     random op script (static/dynamic/optimize/status/stats/save_if_dirty/
+     flush/mark_dirty) with a PATCHED module clock (frozen datetime +

+     storage file) must be IDENTICAL with RUNE_TOKEN_OPTIMIZER_CORE=python
+     (oracle floor) and with the Rust kernel live through the facade's
+     _run_kernel delegation.
+  3. LIVE — dual-mode E2E on the gap fns: the real module-level

+# Freeze rig for the construction_interface dichotomy gap-closing (dichotomy
+# wave #2479 gap port). Auto-imported on interpreter start
+# (PYTHONPATH=scripts/ci_freeze_seams:src) by BOTH the truth generator
+# (scripts/gen_construction_interface_truth.py) and the shared harness's
+# --verify mode, so frozen truth is byte-reproducible in any process:
+#
+# * EVERY RUNE_*_CORE gate is pinned to "python" — the oracle runs its
+#   pure-Python floors end to end (construction_interface, scaffold,
+#   structural_store, construction_decision, construction_mode, capability
+#   ledger, programme continuation, layout contract, ...). The shared
+#   harness's _pin_oracle_cores cannot reach the transitive gates; this
+#   blanket pin is the poisoned-truth law for the whole dependency cone.
+# * The wall clocks are FROZEN: rune.structural_store.now and
+#   rune.scaffold.now (bound import) report CI_FROZEN_NOW. The oracle
+#   stamps need ids, observed_at, checkpoints and closure records through
+#   these two seams; the frozen truth carries the constant instant.
+# * uuid.uuid4 is a deterministic counter (submit_need mints contract ids
+#   from uuid4().hex[:6]); the counter RESETS per rig helper call so a
+#   case's ids depend only on how many mints happen inside it.
+# * CI_FREEZE_HOME (default /tmp/ci_gap_freeze_home) roots every per-case
+#   hermetic store: cases/<case>/proj/.rune/scaffold — deterministic
+#   per-case dirs, because envelopes that carry paths (mini_doc) must
+#   replay byte-identically.
+# * DOC-CARRYING SEAMS: the Rust kernel is a pure doc-in/doc-out membrane
+#   (the store stays with the facade), so every stateful seam below takes
+#   the FULL input doc as an argument — the frozen args replay in the Rust
+#   battery without any store. The input docs are built by the deterministic
+#   builder helpers (build_doc/submit_doc/walk_doc) that the GENERATOR
+#   calls; the seam injects the doc into a fresh hermetic store, runs the
+#   ORACLE method, and returns the envelope (plus oracle-derived doc
+#   outputs where the kernel's contract includes them).
+# * write_mini_doc is redirected into the case dir (the oracle's default
+#   routes through the SOURCE TREE — a repo-dependent absolute path).
+#
+# KNOWN-NONDETERMINISTIC SEAM (memory_consolidation precedent): the
+# obligation ids in _obligations_projection carry Python's
+# process-randomized str hash. Cases whose output carries those ids live
+# in the SEPARATE frozen_ci_truth_hash.json battery (captured + verified
+# with PYTHONHASHSEED=0) and are SHAPE-pinned in the Rust battery and the
+# parity check — never value-frozen in the hash-free battery.

+    import the module-level pin cannot reach). The class patch runs before

+  * uuid.uuid4 is a deterministic counter (ee_freeze_seams precedent) —

+    seam call so a case's ids depend only on the mints inside it.
+  * RUNE_MEMORY_DIR is pinned to a hermetic mkdtemp sandbox BEFORE
+    rune.event_bus imports — journal writes never touch the repo, and
+    event_bus.EVENT_LOG (an import-time constant) resolves to the sandbox.
+  * The seam wrappers (eb_store_path, eb_event_types, eb_content_hash,

+    runs the REAL oracle fns and returns JSON-safe snapshots (journal

+"""Freeze the capability_broker gap-closing truth corpus (dichotomy wave
+#2479 gap-cb tranche).
+
+Drives the LIVE Python oracle (src/rune/capability_broker.py) through the
+shared harness (scripts/freeze_truth.py: RUNE_CAPABILITY_BROKER_CORE=python
+auto-pinned from the module stem, inputs deep-copied per case,
+{"fn","args","kwargs","expected"} envelope) into
+src/rust/capability_broker/frozen_gap_truth.json, embedded VERBATIM by the
+crate's cfg(test) battery (gap_battery.rs, include_str!).
+
+Determinism contract — fixture-home replay (provider_budget law): the
+oracle's module-level card I/O (REGISTRY / CARDS_FILE) resolves through
+memory_env from RUNE_HOME / RUNE_SCRIPTS_DIR, so every case replays
+against a rebuilt fixture home:
+
+    RUNE_HOME       = /tmp/rune_cb_truth_home
+    RUNE_SCRIPTS_DIR= /tmp/rune_cb_truth_home/src/rune
+      src/rune/.microkernel.json           ← SYNTHETIC_REGISTRY (frozen const)
+      memory/index/capability_cards.json   ← STALE_CARDS_SEED, written
+                                              BEFORE the registry (stale arm)
+
+The case list is a REPLAYABLE SCRIPT over that home (stateful mtimes are
+legal because every replay mutates the fixture identically from the same
+canonical seed): staleness flips when load_cards' atomic rebuild rewrites
+the index, and every later score/match/hook case reads the rebuilt index.
+
+WARNING: SYNTHETIC_REGISTRY / STALE_CARDS_SEED below are kept byte-equal
+with the consts embedded in src/rust/capability_broker/src/gap_battery.rs —
+the Rust battery rebuilds the same fixture home from the same values.
+
+Self-verifying (byte-identical law): rebuild → freeze → rebuild → freeze
+(byte-compare) → rebuild → run the shared harness gate in a fresh
+subprocess — must report byte-identical:
+
+    python3 scripts/gen_capability_broker_gap_truth.py   # self-verifies
+
+Standalone re-verify later (fixture rebuilt first):
+
+    python3 scripts/gen_capability_broker_gap_truth.py --setup
+    RUNE_HOME=/tmp/rune_cb_truth_home \
+    RUNE_SCRIPTS_DIR=/tmp/rune_cb_truth_home/src/rune \
+    RUNE_CAPABILITY_BROKER_CORE=python \
+    python3 scripts/freeze_truth.py --verify \
+        src/rust/capability_broker/frozen_gap_truth.json \
+        --module rune.capability_broker
+
+Excluded from the envelope (documented seams, not oracle-freezable — no
+absolute paths, no live module handles): `_cs_core`'s Some arm (returns the
+cs_loader module, not JSON — the pinned-None arm is asserted by the
+both-pins pytest and the kernel mirror by the Rust battery) and the
+corrupt-file / OSError arms of load_cards (seam battery + the live parity
+script drive those against dual fixtures). No absolute path appears in the
+frozen truth.

+"""gen_construction_commands_truth.py — freeze/replay parity truth for
+construction_commands (dichotomy wave, #2479 gap-close tranche).
+
+Freeze mode (default): exercises the LIVE Python oracle
+(src/rune/construction_commands.py — RUNE_CONSTRUCTION_COMMANDS_CORE
+pinned python, poisoned-truth law) across every command/branch and
+records (input, expected) pairs into
+src/rust/construction_commands/frozen_cc_truth.json.
+
+Replay mode (--replay): re-runs the SAME scenarios with the Rust core
+delegation ACTIVE (pin lifted post-import) and asserts both kernel-level
+(loader direct) and facade-level (dispatch end-to-end through a real
+ConstructionInterface + segment-architecture store) parity against the
+frozen file.
+
+Truth groups:
+  * command / dispatch_prep / dispatch_finish — kernel decision
+    surfaces. `command` expected values are literal oracle returns; the
+    prep/finish groups' expected values are the kernel surfaces the
+    facade consumes, derived from the oracle's observable pieces
+    (command() return, ledger state, interface envelope rules) — the
+    facade-only dispatch_exec group pins the END-TO-END equivalence.
+  * dispatch_exec — facade-only (real interface + segment-store IO
+    stays in Python): whole dispatch runs against seeded stores.
+
+Clock law: the oracle's recorded_at seam is time.strftime(time.gmtime())
+— the generator patches the ORACLE module's `time` attribute with a
+frozen gmtime, so kernels receive `now` as an argument (recorded_at is
+byte-stable across processes).
+
+Idempotency-ledger law: the module-global `_outcomes` ledger evolves
+across a case SEQUENCE within one process; freeze and replay run the
+identical case list with unique per-case command ids, so ledger
+evolution is identical. Kernel cases are otherwise stateless
+(prior_outcome is an explicit input; replay-pair cases derive prior
+from the oracle's own first-delivery envelope).
+
+Hash law: PYTHONHASHSEED=0 enforced by re-exec (resume projections
+derive obligation ids from hash() — frozen truth must never embed
+process-random hashes).

+"""Freeze the dichotomy-wave gap truth for src/rune/construction_interface
+through the SHARED harness (scripts/freeze_truth.py — one law).
+
+The oracle is a stateful facade (ConstructionInterface over a Scaffold
+store) with clock/uuid nondeterminism, so this generator runs under the
+freeze rig (scripts/ci_freeze_seams/sitecustomize.py):
+pinned RUNE_*_CORE=python floors, frozen clock, deterministic uuid mint,
+hermetic per-case stores (deterministic per-case dirs — envelopes that
+carry paths, like mini_doc, replay byte-identically), and DOC-CARRYING
+seam bindings the shared harness can getattr: the Rust kernel is a pure
+doc-in/doc-out membrane, so every stateful case carries the full input
+doc in its args and replays in the battery with no store.
+
+Run (from the repo root):
+    rm -rf /tmp/ci_gap_freeze_home
+    CI_FREEZE_HOME=/tmp/ci_gap_freeze_home \
+      PYTHONPATH=scripts/ci_freeze_seams:src \
+      python3 scripts/gen_construction_interface_truth.py
+
+Verify (byte-identical, same rig):
+    CI_FREEZE_HOME=/tmp/ci_gap_freeze_home \

+
+Every public function and branch is exercised. The obligation-id seam
+(_obligations_projection carries process-randomized str hash) lives in
+the SEPARATE frozen_ci_truth_hash.json battery (captured + verified with
+PYTHONHASHSEED=0) and is SHAPE-pinned downstream — never value-frozen

+"""gen_construction_projection_truth.py — factory wave GAP truth for
+construction_projection.
+
+Freezes the oracle behavior of ALL FOUR public functions (the audit named
+three gaps: _contract_entity, validate, write_mini_doc; project's
+pre-existing kernel path is replayed too) through the SHARED harness
+(scripts/freeze_truth.py — one law).
+
+Runs under the freeze rig (scripts/cproj_freeze_seams/sitecustomize.py —
+PYTHONPATH-imported by BOTH this generator and --verify): pinned floor
+(RUNE_CONSTRUCTION_PROJECTION_CORE=python), a JSON-specified fake scaffold
+(load() doc + project_id), and a pinned fake bridge for
+rune.event_wait.operation_wait (found / no-record / OSError /
+RuntimeError / no-lookup rows). write_mini_doc rows write into a hermetic
+fixed-path scratch dir and freeze the markdown BYTES + the file NAME —
+never an absolute path (quirks: machine-specific paths).
+
+The PROJECT rows carry the oracle kwargs in the harness-kwargs slot, and
+the rig echoes the adapter-resolved bridge scalars (waiting_state /
+live_correlation) inside the expected wrapper — the Rust battery rebuilds
+its kernel calls from the same rows (the SPEC-grammar law).
+
+Run (from the repo root):
+    PYTHONHASHSEED=0 PYTHONPATH=scripts/cproj_freeze_seams:src \
+      python3 scripts/gen_construction_projection_truth.py

+(null entities, non-dict projection, non-str slicing, non-str blocker

+"""gen_contracts_gap_truth.py — freeze/replay parity truth for the contracts
+gap-close (dichotomy wave, #2479 tranche).
+
+Freeze mode (default): exercises the LIVE Python oracle
+(src/rune/contracts.py — the 7 functions the audit names as missing:
+_ct_core, _resolve_and_project, _run_contract_python, capture_signatures,
+save_signatures, load_signatures, main, plus run_contract/run_all_contracts
+companions) and records the truth into
+src/rust/contracts/src/ct_gap_truth.json.
+
+The file has two sections:
+
+* ``cases`` — shared-harness schema, re-verifiable with
+  ``PYTHONPATH=src python3 scripts/freeze_truth.py --verify
+  src/rust/contracts/src/ct_gap_truth.json --module rune.contracts``.
+  Contract-taking fns cross via the harness ``recv`` form: the receiver
+  spec rebuilds a live ``Contract`` (cls __new__ + attrs, no IO) and the
+  fn is called as an unbound-style first argument. ``expect_type`` stays
+  None because a type object is not JSON-safe — the type-check branches
+  are covered by the pre-existing 58-case ``ct_truth.json`` battery,
+  replayed through the new ``_run_contract_python`` Rust kernel.
+  ``check_signature_drift()`` reads the real signatures file (no args) so
+  it stays out of the harness set (its compare kernel is already frozen
+  in ct_truth.json's drift_cases).
+* ``extra`` — oracle-derived rows the harness cannot round-trip
+  (``ContractResult`` dataclasses are not JSON-native; ``save/load`` touch
+  the signatures file; ``main`` drives argv/stdout/exit-code):
+  ``result_cases`` (run_contract / _run_contract_python asdicts),
+  ``run_all`` (42 asdicts), ``probes`` (loader-state -> gate bool),
+  ``file_cases`` (per-case deterministic dirs, no paths in expectations),
+  ``main_cases`` (argv/stdout/exit-code). Embedded VERBATIM in the
+  ``gap_battery`` alongside ``cases``.
+
+Replay mode (--replay): re-runs the SAME scenarios with the Rust core
+delegation ACTIVE and asserts facade-level and kernel-level parity.
+
+Poisoned-truth law: freeze pins RUNE_CONTRACTS_CORE=python BEFORE any
+oracle import (the shared harness also pins it per module stem).
+Mutation law: case inputs are deep-copied BEFORE they reach the oracle.
+Deterministic-dirs law: file/main cases redirect SIGNATURES_FILE into
+/tmp/ct-gap-freeze/<case>/ (fixed names — identical at freeze, --verify
+and --replay); expectations never embed the paths.

+"""gen_cron_engine_gap_truth.py — cron-engine gap-closing truth battery
+(#2479 dichotomy wave, GO side).
+
+Closes the PARTIAL audit gaps: to_dict, run_task (method + module),
+fire_on_task_complete, start/stop, _run_loop, _execute_task,
+_log_execution/_log_error, get_cron_engine/start_engine/stop_engine
+(parseCronField/shouldRun already existed; extra branch rows frozen too).
+
+Uses the SHARED harness (scripts/freeze_truth.py) with the hook_engine
+wrapper-shim law: CronEngine methods are stateful and touch the clock,
+HOME (~/.rune/cron.log), subprocesses and threads — none of which the
+bare harness pins. Every row is frozen against a module-level WRAPPER
+(_ce_* below, in THIS module registered as
+gen_cron_engine_gap_truth_shims):
+
+  * FROZEN clock: cron_engine.datetime patched with the harness's frozen
+    class (module-level import → the patch reaches every method).
+  * HERMETIC per-row HOME: fresh mkdtemp per wrapper call; every path in
+    the capture is tokenized to <CE_HOME> (no absolute paths in truth).
+  * _run_loop rows: cron_engine.time swapped for a stopper whose sleep()
+    flips the engine's running flag — exactly ONE loop iteration, then a
+    clean exit (deterministic under the frozen clock).
+  * record_failure (rune.subsystem_health) is neutralized during rows —
+    the oracle imports it lazily inside except blocks, and its ledger
+    writes are outside the captured surface.
+  * capture shape: {"result", "post": {running, storage_path, tasks
+    (insertion-ordered [name, to_dict] pairs), _last_run_minute},
+    "files" (~/.rune dir inventory), "storage", "log"}.
+
+Verify (this file ships its own --verify — same byte-compare law as the
+harness, plus the shim-module registration the stock CLI cannot do):

+"""gen_drift_compression_truth.py — freeze drift_compression oracle truth
+for the memory_scoring gap-close battery (dichotomy wave, #2479 tranche).
+
+Freezes the PURE, replayable oracle surface (the six _py_* kernels:
+_py_get_compression_ratio, _py_compress_text, _py_compress_entry,
+_py_should_warn, _py_warn_before_compress, _py_get_compression_stats)
+through the SHARED harness (scripts/freeze_truth.py) into
+src/rust/memory_scoring/src/frozen_dcomp_truth.json — the freeze_truth
+list format, so `freeze_truth.py --verify` re-freezes it byte-identically
+against the live oracle (byte-identical law).
+
+Poisoned-truth law: RUNE_MEMORY_CORE=python is pinned BEFORE any import —
+drift_compression's delegation chain runs through drift_core._ms_core,
+which reads RUNE_MEMORY_CORE (the harness's stem-derived pin cannot reach
+a cross-module chain). Freezing the _py_* kernels directly makes the truth
+delegation-proof by construction: no pin can poison a pure function.
+
+Boundary law: the sqlite read in the public get_compression_stats(db)
+stays in the Python facade — _py_get_compression_stats(rows) freezes the
+math on the fetched triples [rock_status, wash_count, text_len], exactly
+the payload the Rust kernel receives. The db-level seam (SQL, status
+filtering, None coercion of SQL nulls) is covered live by
+scripts/check_drift_compression_parity.py, not by frozen truth (a sqlite
+connection is not JSON-freezable).
+
+No clock, no HOME, no file seams in this module — no rig needed.

+"""gen_drift_core_truth.py — factory wave GAP truth for drift_core.
+
+Freezes the oracle behavior of the 8 audit-gap functions (dichotomy wave
+#2479: _ms_core, _now_iso, promote_entry, compute_fama,
+compute_drift_velocity, compute_drift_direction, pre_commit_gate,
+pre_commit_gate_entry) plus scoring-surface regression rows (compute_value,
+check_promotion_eligibility) through the SHARED harness
+(scripts/freeze_truth.py — one law).
+
+Runs under the freeze rig (scripts/dc_freeze_seams/sitecustomize.py —
+PYTHONPATH-imported by BOTH this generator and --verify): pinned floor
+(RUNE_DRIFT_CORE=python), frozen clock (RUNE_FROZEN_NOW reaches _now_iso
+and the velocity cutoff through the harness's module-datetime patch),
+hermetic per-row scratch store, embeddings off, and the db-carrying seams
+(promote/fama/velocity/direction/gate) that drive the REAL oracle fns with
+JSON-safe shapes. The memory_scoring kernel is intentionally LIVE (its
+Python oracle is retired and raises — determinism requires the built .so;
+the rig fails loudly when it is missing).
+
+Run (from the repo root, under the sqlite-vec venv):
+    PYTHONHASHSEED=0 PYTHONPATH=scripts/dc_freeze_seams:src \
+      ~/.venvs/memory/bin/python3 scripts/gen_drift_core_truth.py
+
+Verify (byte-identical, same rig):
+    PYTHONHASHSEED=0 PYTHONPATH=scripts/dc_freeze_seams:src \
+      ~/.venvs/memory/bin/python3 scripts/freeze_truth.py --verify \
+      src/rust/drift_core/frozen_truth.json \
+      --module rune.drift_core
+
+Case map (every gap branch):
+  * _now_iso        — None (frozen clock) + passthrough.
+  * _ms_core        — probe contract True under the rig (kernel live).
+  * compute_value   — no-goals + goals rows (ms-kernel regression).
+  * check_promotion_eligibility — eligible tuple row.
+  * pre_commit_gate_entry — short / refusal / well-formed critics.
+  * dc_freeze_gate  — the empty oracle body (None → null).
+  * dc_freeze_promote — not-found / already-rock / ineligible-low-wash /
+                      washable→established / established→rock /
+                      unknown-status→established; `after` pins the UPDATE.
+  * dc_freeze_fama  — empty ids / all-valid / mixed / missing rows /
+                      inactive / null-wash+established.
+  * dc_freeze_velocity — inside+outside window / over-threshold alert /
+                      days=0 (max(1,·) floor) / integral 2.0 rounding.
+  * dc_freeze_direction — stable / drifting / empty store / rock-only.

+  * eb_store_path — the canonical journal path under the hermetic RUNE_MEMORY_DIR
+    sandbox, normalized to EB_SANDBOX (machine paths never enter truth).
+  * eb_event_types — EVENT_TYPES in definition order (json.dumps keeps it).
+  * eb_emit — envelope build + durable append: schema_version-first to_dict,
+    partition_key from source-or-system, payload_hash truthiness ({}, 0 and
+    None hash ""), minted event_id / frozen clock, and the loud ValueError
+    branches (non-str source: dict/int/NoneType/float/bool/list — message
+    carries the Python type name, NOTHING written).
+  * eb_emit_line — the exact journal LINE bytes (json.dumps(to_dict,
+    sort_keys=True) + newline).
+  * eb_log — replay + event_type filter + events[-limit:] truncation
+    (limit 0 → ALL — the -0 slice quirk; -1 → [1:] drops the first).
+  * eb_log_corrupt — the typed corrupt-line raise (message-only contract).
+  * eb_stats — (total, by_type) with by_type in first-occurrence order.
+  * eb_handle_hook — hook.<event> vocabulary prefix, source microkernel,
+    payload shaping (str → json.loads with the raw[:200] fallback; dict →
+    str(v)[:200] CODEPOINT truncation with Python repr forms; falsy data
+    stays {}), and the journal replay after each hook.

+"""gen_event_envelope_truth.py — shared-harness truth battery for the
+event_envelope gap closure (#2479, contract factory-gap-ee).
+
+Uses scripts/freeze_truth.py (the ONE truth law) under the
+scripts/ee_freeze_seams sitecustomize rig (PYTHONPATH carries BOTH) to
+freeze src/rune/event_envelope.py behavior for the Go port at
+src/go/event-bus:
+
+  * classify_authority / classify_urgency — the \\b<word>\\b regex
+    semantics incl. the multi-word amendment list ("stop doing" is NOT
+    bare "stop"), punctuation adjacency ("stop," still matches), and the
+    channel-default fallbacks.
+  * create_envelope — the legacy direct-constructor path (auto authority
+    + urgency from payload["text"], explicit overrides, minted
+    event_id/timestamp under the deterministic uuid + frozen clock).
+  * EventEnvelope.create — the canonical-bridge classmethod: event_type
+    follows the CHANNELS prior vocabulary (tool -> tool_result),
+    channel-not-in-CHANNELS fallback chain, and the nested canonical
+    record rides in asdict form (_canonical).
+  * to_dict — the 9-key legacy dict.
+  * to_canonical_dict — schema_version-1 dict with content-addressed
+    payload_hash (key order: schema_version first, payload_hash in
+    place), incl. the loud RuntimeError branch for un-bridged
+    envelopes (message-only contract).
+  * test_envelope — the in-module self-test's exact stdout bytes
+    (captured under the rig's deterministic ids).
+  * CHANNELS / AUTHORITY_CLASSES — the constant tables.

+"""gen_microkernel_gap_truth.py — microkernel gap-closing truth battery
+(dichotomy wave #2479, worktree rune-wave-cq).
+
+Closes the PARTIAL audit gaps: now_iso, discover, _extract_manifest,
+_load_registry, _save_registry, _run_hook (fire's hook runner).
+
+Uses the SHARED harness (scripts/freeze_truth.py): RUNE core pinned to
+python, deep-copied inputs, envelope with its own frozen_now:
+
+  PYTHONPATH=src python3 scripts/freeze_truth.py \
+      --verify src/go/microkernel/truth_microkernel_gap.json \
+      --module rune.microkernel
+
+STATEFULNESS / DETERMINISM LAWS:
+  * _extract_manifest takes an fpath — the shim carries the file CONTENT
+    in args, writes a temp file, calls the real oracle fn, returns the
+    parsed manifest (paths never enter the result).
+  * discover iterates os.listdir (filesystem order) and stamps absolute
+    _file paths — the shim installs a fixture dir, pins os.listdir to the
+    EXACT frozen filename order (sorted — matches the Go port's
+    os.ReadDir), calls the real discover(), and normalizes every path to
+    <dir>/<fname> stubs. Machine-independent, replay-stable.
+  * _run_hook is a closure inside fire() — it is exercised through the
+    real fire() with ONE listener per branch class (fixture scripts are
+    in-file constants: deterministic stdout/stderr). wall-clock durations
+    (duration_ms / total_duration_ms) are normalized to "<ms>" — the
+    no-wall-clock law.
+  * _load_registry/_save_registry: missing file, corrupt file, full-shape
+    file (verbatim load), and a save->load roundtrip of the default shape.

+Usage: python3 scripts/gen_microkernel_gap_truth.py   (from repo root)

+"""gen_model_registry_gap_truth.py — model_registry gap-closing truth
+battery (dichotomy wave #2479 gap port).
+
+Closes the PARTIAL audit gaps: to_dict, get_profile, get_enabled_profiles,
+get_profiles_by_tier, list_profiles, test_registry (get_cheapest_capable
+and resolve_context_budget existed; resolve's constants were WRONG in the
+2026-10-09 Go port — toolReserve 2048 vs the oracle's TOOL_RESULT_RESERVE
+1024 — and task_kind was missing entirely; the frozen rows pin the live
+constants).
+
+Uses the SHARED harness (scripts/freeze_truth.py) through the
+scripts/mreg_freeze_seams rig (auto-imported sitecustomize that binds
+JSON-safe seam_* wrappers onto the oracle module — registry methods
+return ModelProfile dataclass instances, which the harness cannot
+serialize). The oracle is PURE Python: no loader seam (RUNE pin vacuous),
+no clock, no HOME — envelope frozen_now is conventional only.
+
+Registry states ride as ORDERED [tier_key, profile_dict] PAIRS (dict
+insertion order is load-bearing at three points: get_profile is a KEY
+lookup while get_profiles_by_tier matches the tier ATTRIBUTE;
+resolve_context_budget breaks on the FIRST id match; list_profiles
+returns values in insertion order). Receiver-style truth is NOT possible
+for this module — resolve_context_budget is module-level, so the shared
+harness's fn(inst, ...) call would bind the instance to model_id; the
+raw-receiver branch is pinned through a __new__ seam instead.
+
+Regenerate + re-verify (byte-identical law — two runs, then verify):
