Subject: [PATCH 1/7] feat(ci,ml): Tier-3 live-prover provisioning + uncap Flux
 training

.github/workflows/live-provers.yml
  Replace Tier-3 placeholder with a per-backend matrix.  Live-provisioned
  (apt / upstream tarball): tamarin, proverif, metamath, twelf, ortools.
  Deferred-to-Containerfile with explicit skip note: hol4, acl2, scip,
  imandra.  Each job probes the binary and runs the single matching case
  from tests/live_prover_suite.rs with continue-on-error while Wave-3
  wires up.

tests/live_prover_suite.rs
  Add #[tokio::test] entries for all nine Tier-3 backends and extend
  kind_label with their display names.  Tests SKIP when the binary is
  absent on PATH (existing `which` probe), so running locally or in PR
  CI costs nothing; only the weekly tier3 matrix exercises them.

src/julia/run_training.jl
  Drop the hardcoded max_proof_states=50_000 cap that made the expanded
  corpus pointless.  Default 200k on GPU / 50k on CPU, overridable via
  ECHIDNA_MAX_PROOF_STATES (0 = unlimited).  ECHIDNA_NUM_EPOCHS and
  ECHIDNA_NUM_NEGATIVES gain the same treatment.  Required before
  retraining on the 2026-04 corpus expansion.

Subject: [PATCH 2/7] feat(corpus): non-interactive upstream provisioning +
 extractor driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

scripts/provision_corpora.sh
  Single source of truth for every prover's upstream corpus mirror.  A
  catalogue entry per source (52 total: 45 git clones, 7 manual/gated)
  binds the external_corpora/<name>/ path the extractors expect to a
  concrete clone URL, replacing the comments-scattered-across-54-files
  pattern.  Idempotent, non-interactive, retries once on network
  failure, continues past a dead mirror so one 404 doesn't abort a
  40-source run.  --list, --status, --force, --all, and named-subset
  selection.  Meant for a nightly cron or a Justfile recipe.

scripts/extract_all.sh
  Composable companion.  Runs every scripts/extract_*.jl (or a named
  subset) under the src/julia Julia project and collects failures into
  a non-zero exit code.  Short-circuits gracefully when an extractor's
  upstream is absent (the extractors themselves already handle that).
  Together with provision_corpora.sh + run_training.jl this gives a
  three-step end-to-end retrain recipe: provision → extract → train.

Motivation: the existing expand_training_data.sh was interactive
(read -p) and only knew about three sources, so no CI job could grow
the corpus without human input.  Closing that gap unblocks the 100k
per-prover target.

+# ECHIDNA — Non-interactive upstream corpus provisioning.
+#
+# Clones the upstream mirror of every theorem-prover corpus the extractors
+# under scripts/extract_*.jl expect at external_corpora/<name>/.  Each
+# clone uses --depth=1 to keep the bandwidth bill finite (~4-8 GB total
+# when all sources are selected).
+#
+# Usage
+# -----
+#   scripts/provision_corpora.sh [NAME ...]     # provision the named sources
+#   scripts/provision_corpora.sh --all          # provision every source
+#   scripts/provision_corpora.sh --list         # print the source catalogue
+#   scripts/provision_corpora.sh --status       # show which sources are on disk
+#
+# Selection names match the external_corpora/<name>/ directory each extractor
+# expects.  Unknown names exit non-zero so typos fail loudly in CI.
+#
+# Behaviour
+#   * If external_corpora/<name>/ already exists the source is skipped
+#     (idempotent; safe to re-run).  Pass --force to re-clone into a
+#     fresh directory.
+#   * Network failures are retried once; a failure after that is logged
+#     and the script continues to the next source (so a single offline
+#     mirror doesn't abort a 40-source provisioning).
+#   * Designed to be callable from a Justfile recipe or a nightly CI
+#     workflow.  No interactive prompts, ever.

Justfile
  Three new recipes that compose the scripts landed in 9df340c into an
  idiomatic end-to-end retrain flow:

    just provision-corpora [NAMES...]   # scripts/provision_corpora.sh
    just corpora-status                 # on-disk report
    just extract-corpora [NAMES...]     # scripts/extract_all.sh
    just retrain                        # src/julia/run_training.jl
    just corpus-refresh                 # all three, in order

  Each step is idempotent; re-running the pipeline only touches what
  has changed.  The retrain recipe honours the env-var knobs added in
  5611cb2 (ECHIDNA_MAX_PROOF_STATES, ECHIDNA_NUM_EPOCHS,
  ECHIDNA_NUM_NEGATIVES), so:

    ECHIDNA_MAX_PROOF_STATES=0 just corpus-refresh

  re-baselines MRR against the full expanded corpus on GPU hardware.

Subject: [PATCH 4/7] feat(verisim): first-class Proof / TacticApplication /
 ProofVersion / ProofStateRecord
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

src/rust/verification/proof.rs
  New module (verisim-feature-gated) materialising the four entities the
  E-R audit flagged as missing from the Verisim schema.  Each closes one
  of the FK-discipline gaps identified in the 2026-04-19 audit:

  * Proof{id, goal_hash, theorem_hash, theorem_name, prover, first_seen}
    makes the SHA-256 digest already produced by
    proof_encoding::proof_identity() a first-class row.  theorem_hash
    (new helper theorem_identity) and goal_hash let cross-prover and
    cross-goal joins index on fixed-width columns without re-deriving
    the triple from the primary key.

  * TacticApplication{proof_id, step, tactic, goal_hash, status,
    goals_after, duration_ms, applied_at} persists the proof DAG.
    Success/Closed/Error TacticStatus is kept (not just success) so
    MCTS/agentic search retains failed-branch training signal.

  * ProofVersion{proof_id, version, snapshot_id, goals_remaining,
    is_qed, actor, recorded_at} is the append-only audit log that
    OctadPayload.temporal.versions currently lacks — the latter is
    render-only; this is durable.  `initial()` and `next()` chain
    monotonically so versions never collide.

  * ProofStateRecord{proof_id, step, goal_hash, prover, prover_version,
    state_cbor_b64, features, relevant_premises, label_confidence,
    source} is the typed corpus schema replacing the ad-hoc JSONL dict.
    state_cbor_b64 round-trips the tree structure the JSONL format
    loses; label_confidence separates human-verified ground truth from
    weak heuristics; prover_version attributes MRR deltas to solver
    builds.

  The module adds 8 unit tests (hash-derivation correctness, FK wiring,
  monotonic version chaining, QED marking, round-trip serde).  Existing
  OctadPayload posting continues unchanged — these rows are intended to
  be written alongside, not instead of, the octad, via an incremental
  migration path.

src/rust/verification/mod.rs
  Export the new types behind the existing `verisim` feature gate,
  matching how proof_encoding is gated.

src/rust/proof_encoding.rs + src/rust/verisim_bridge.rs
  Drive-by fix: the `verisim` feature tests referenced
  ProverKind::Lean4 (doesn't exist; the Lean 4 variant is ProverKind::Lean,
  Lean 3 is the sibling ProverKind::Lean3) and a hardcoded "Lean4" Debug
  string.  Restoring the 27 previously-uncompilable verisim-feature
  tests so the new proof.rs tests can share the harness.

Test counts: 613 default, 640 with --features verisim (0 failures).

+//! Persistent proof entities for the Verisim E-R schema.
+//!
+//! The existing `proof_encoding::proof_identity` function produces a stable
+//! SHA-256 hex digest for every `(theorem, goal, prover)` triple, but that
+//! digest lives only as `OctadPayload.key`.  Downstream entities
+//! (ProofAttempt, PortfolioResult, MutationResult, ParetoEntry, certificates,
+//! integrity records, training corpora) cannot FK into a `Proof` row because
+//! no `Proof` row exists — they each carry their own loose references to
+//! theorem names and prover strings.  This module materialises the missing
+//! entities so the proof territory has an actual map:
+//!
+//!   * [`Proof`]             — stable primary key with explicit
+//!                             `theorem_hash` and `goal_hash` for cross-prover
+//!                             and cross-goal joins.
+//!   * [`TacticApplication`] — one row per tactic step; makes the proof DAG
+//!                             reconstructable.
+//!   * [`ProofVersion`]      — append-only snapshot log so the temporal
+//!                             evolution of a proof is durable, not just
+//!                             renderable in `OctadPayload.temporal`.
+//!   * [`ProofStateRecord`]  — typed training-corpus schema replacing the
+//!                             untyped JSONL dict.
+//!
+//! All four types serialise to JSON/CBOR and are intended to be posted to
+//! Verisim alongside — not instead of — the existing `OctadPayload`.  An
+//! incremental migration strategy keeps the current octad-posting path
+//! working while downstream consumers start reading the new FK-structured
+//! tables.

Subject: [PATCH 5/7] feat(corpus): align premise proof_ids with UNIFIED after
 merge
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

scripts/align_premises.jl
  New Julia script that reconciles the three-way id-space bug found
  during today's retrain:

    * per-prover extractors emit proof_state.id and matching
      premise.proof_id sharing a local integer id space
    * scripts/merge_corpus.jl:350-352 dedupes proof_states by
      (prover, theorem) and rewrites every id to a fresh sequential
      counter 1..N in proof_states_UNIFIED.jsonl
    * the premise files retain their original extractor ids, so the
      dataloader's proof_id join matches ~0% of records — today's
      retrain saw 1 392/50 000 = 2.8% coverage

  Fix: rebuild premises_COMPLETE.jsonl keyed on (canonical_prover,
  theorem) — the same pair merge_corpus.jl dedupes on, which is
  durable across the id rewrite.  For every premise record, look up
  the fresh id assigned by the merge and rewrite proof_id := UNIFIED_id.
  Records whose theorem is not in UNIFIED get dropped and counted.
  Expected coverage jump: 2.8% → ~60–80% of proof_states with at
  least one matched premise, ~20-30x more training examples.

  Canonicalisation table held in lockstep with merge_corpus.jl's
  PROVER_CANONICAL.  Stats written to premises_ALIGNED_stats.json
  alongside the output.

Justfile
  Add `merge-corpora` (runs scripts/merge_corpus.jl) and
  `align-premises` (runs the new script) recipes and insert them
  into the corpus-refresh chain between extract-corpora and retrain,
  so the full pipeline is now: provision → extract → merge → align →
  retrain.  Individual recipes remain callable for targeted work.

+# align_premises.jl — rebuild training_data/premises_COMPLETE.jsonl with proof_ids
+# that match the fresh sequential ids written by merge_corpus.jl into
+# training_data/proof_states_UNIFIED.jsonl.
+#
+# Background
+# ----------
+# The per-prover extractors (scripts/extract_*.jl and scripts/max_extract_*.jl)
+# emit proof_states and premises sharing a per-extractor-local integer id space:
+#
+#     {"id": 60123, "prover": "Lean", "theorem": "Foo.bar", ...}     (proof_state)
+#     {"proof_id": 60123, "prover": "Lean", "theorem": "Foo.bar", ...} (premise)
+#
+# scripts/merge_corpus.jl then writes proof_states_UNIFIED.jsonl after dedup
+# by (prover, theorem) and **rewrites every proof_state's id to a fresh
+# sequential counter (1..N)**.  The premise files retain the original
+# extractor ids, so proof_state.id and premise.proof_id no longer share an id
+# space — the dataloader's join by proof_id matches ~0% of records.
+#
+# This script rebuilds premises_COMPLETE.jsonl using the
+# (canonical_prover, theorem) pair as the durable join key (which merge_corpus
+# already guarantees is unique within UNIFIED).  For every premise record,
+# we look up the fresh id assigned by merge_corpus and rewrite
+# `proof_id := UNIFIED_id`.  Records whose (prover, theorem) does not appear
+# in UNIFIED are dropped and counted.

Subject: [PATCH 6/7] chore(lints): clear all 4 stable + 2 verisim cargo
 warnings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

src/rust/agent/memory.rs, src/rust/vcl_ut.rs
  Drop `warn` from the default-feature `tracing` import — the macro is
  only called inside #[cfg(feature = "verisim")] blocks.  Re-import it
  behind the same gate so verisim builds keep compiling.

src/rust/vcl_ut.rs
  Move the `let theorem = ...` binding inside the existing
  #[cfg(feature = "verisim")] block at execute_find_proof — it's only
  used by the verisim octad-key path.  Removes the unused-variable
  warning under the default feature without sprinkling _theorem.

src/rust/provers/mod.rs
  Drop the `"lp"` arm from the Dedukti file-extension match (line
  1359).  `.lp` is already claimed by GLPK seventeen lines above, so
  the Dedukti branch was unreachable.  Inline a comment explaining
  the .lp ambiguity (LP/MIP vs lambdapi) and pointing readers at
  detect_from_file_content() for content-aware disambiguation.

src/rust/verisim_bridge.rs
  Drop unused `info` from the tracing import (only debug + warn are
  called) and unused `Tactic` from the top-level core import (only
  the test module references it; added there explicitly instead).

Test counts unchanged: 613 default, 640 verisim, 0 failures.

Subject: [PATCH 7/7] fix(bench): add missing diagnostics field in routing
 bench DispatchConfig

dispatch.rs:101 added a `diagnostics: bool` field to DispatchConfig
under #[serde(default)] but routing_benchmarks.rs:305 still constructs
the config with the old field set, breaking `cargo bench --no-run`.

Add `diagnostics: false` to match the field set.  Production callers
keep using DispatchConfig::default() so this only affects the bench.
