+(contract BUILDER-2026-10-07T16:31:17Z-997c9d).
+
+Why: batch 1's truth.json encoded the LEXICON DEGRADE — the phantom shadow
+("lexicon module unavailable — strength gate only") — because
+lexicon_evolution.py was absent when it was generated. The phantom has now
+been recovered from provenance (commit 5749029), so the LIVE oracle returns
+real lexicon verdicts and the Go port must match THEM.
+
+What this does:
+1. Rewrites ONLY the fn=='le_promote_eligible' cases inside truth.json,
+   regenerated against the live curator.le_promote_eligible (which now
+   delegates to the recovered lexicon_evolution). Other cases untouched.
+2. Emits truth_lexicon.json — direct live-oracle cases for the recovered
+   module's full surface: coherence (conflict/consistent/novel), grounded,
+   distinctive_terms, promote_eligible (shared / novel-grounded /
+   novel-parked / no-signal / strength-gate).
+
+Note on `existing`: the truth carries the block values as a single string;
+the oracle is called with a one-element list ([existing]) — the batch-1
+convention, documented here so the Go test wraps identically.

+HERMETICALLY (contract BUILDER-2026-10-07T16:11:35Z-70ca24-unknown).
+
+Why: the original batch-2/3/4 generators baked the generation host's temp
+paths (/mnt/workdrive/tmp*) into truth_fileops.json / truth_ops.json /
+truth_paths.json — inputs AND expectations. CI's runner user cannot read
+those paths, so the parity gate failed with permission-denied (go-surface,
+run 19792 job 56712) despite a locally green tree.
+
+Design (the environment leak, closed):
+- Fixtures are created at generation time under roots the ORACLE ITSELF
+  allows: read root = first creatable dir in ALLOWED_READ_DIRS (prefers
+  /tmp), write root = first creatable dir in ALLOWED_WRITE_DIRS.
+- Every occurrence of those roots — in inputs AND expectations — is
+  replaced with {{TMP}} / {{WROOT}} placeholders.
+- Each truth file carries a `fixtures` manifest (files + dirs) so the Go
+  test recreates the SAME fixture content under ITS OWN roots at runtime.
+  Both sides then run the same case semantics on their own environment;
+  substituted bytes must agree exactly.
+- The grep-hit comparison stays order-insensitive (sorted line sets) on the
+  Go side: the oracle's os.walk order is OS-scheduling dependent, not a
+  parity-relevant property. Everything else is exact after substitution.
+
+Oracle authority: src/rune/tool_executor.py is called LIVE for every case
+except the two cmd_gate verdicts whose oracle path would execute a shell
+command (plain_ok / shell_ok use harmless commands instead: "ls -la" and
+"true" — the gate branches they exercise do not inspect command content
+beyond non-emptiness).

+"""polyglot_lint.py — the language-AWARE lint gate (contract
+BUILDER-2026-10-07T20:01:40Z-ac6140).
+
+Why: the pipeline linted Python hard (ruff + ratchet) but Rust NOT AT ALL
+(crates build, never clippy) and Go only via vet (gofmt drifted across 41
+files, including landed batches). This gate applies the RIGHT linter to
+whatever changed:
+
+    Python → ruff check
+    Go     → go vet (per module) + gofmt -l (formatting is a gate)
+    Rust   → cargo clippy -- -D warnings (per changed crate) + cargo fmt --check
+    other  → noted and skipped
+
+Modes:
+    (default)        changed files vs the push range (git diff against
+                     origin/master / the last push ref; falls back to the
+                     last commit when no upstream exists)
+    --all            full tree
+    --files a,b,c    explicit list
+
+Exit non-zero on any finding. The cron fault-watcher and the pre-push
+routine both run this; CI runs the Go+Rust halves natively.
+
+Usage:
+    python3 scripts/polyglot_lint.py            # changed-only
+    python3 scripts/polyglot_lint.py --all      # everything
