+## ISS-FISHERZ-ENCODE-SATURATES-SILENTLY — out-of-family cosines encode to the edge code with no flag (2026-10-23)
+
+**Status:** OPEN. **Basis:** VERIFIED-IN-CODE (`crates/bgz-tensor/src/fisher_z.rs:67`, `i8_val.clamp(-128.0, 127.0) as i8`, read at `main` `8f610a85`) + MEASURED.
+**Fruit:** Low-hanging
+
+- `FisherZTable::encode` clamps anything beyond the family's
+  `[z_min, z_max]` onto the edge code, and nothing reports it. An
+  out-of-family pair therefore reads as maximal in-family similarity. Below
+  `z_min` the value lands on −128, which `decode` maps one step past `z_min`.
+- **Receipt:** P-D3, `crates/bgz-tensor/tests/p_d3_ood_support_probe.rs`
+  (`entries/2026-10-22-probes-pd4-pe2-pd3.md`). The clamp condition holds on
+  0/120 in-range cosines and 403/403 saturating ones, and
+  `encode(1.0) == encode(0.99995)`.
+- This is H5 of the H1–H5 falsifiers (EXO-50, session_01G22yT6 /tanh-01). H5
+  was proposed and never added.
+- **What closes it:** a checked encode that reports out-of-range values (a
+  count, or an `Option`) beside the existing one, with no change to the code
+  points. Add a can-fire test (a value past `z_max` is reported) and a
+  stay-silent test (in-family values are not).
+- Note: until TD-BGZ-TENSOR-INTEGRATION-TESTS-UNGATED-1 is fixed, a test under
+  `bgz-tensor/tests/` does not run in CI. Put this one in the crate's lib
+  tests.

+## TD-NARS-REVISION-UNGUARDED-CAUSAL-EDGE-ISA-1 — `Opcode::Revision` pools a duplicated source; a measured site of TD-NARS-REVISION-UNGUARDED (2026-10-23)
+
+**Status:** OPEN. **Basis:** VERIFIED-IN-CODE + MEASURED.
+**Fruit:** High-signal
+
+- `crates/causal-edge/src/isa.rs:209` `truth_code` (and `:197` `truth`) runs
+  `Opcode::Revision` through `truth::revision` on four scalars. There is no
+  stamp, so nothing can see that the two operands share evidence.
+- **Receipt:** P-E2, `crates/causal-edge/tests/p_e2_stamp_gate_probe.rs`
+  (`entries/2026-10-22-probes-pd4-pe2-pd3.md`). Revising one source with
+  itself k times starting from c = 128 gives c = 170 / 204 / 227 at
+  k = 2 / 4 / 8, with posterior sd ratio 0.837 / 0.658 / 0.491.
+- The test-local ONA-shape gate already exists in that file and is
+  disable-verified. It checks stamp overlap first, and on overlap keeps the
+  stronger belief. With it, duplicates give Δc = 0 and an sd ratio of 1.000,
+  while disjoint sources still pool.
+- This is the same defect as TD-NARS-REVISION-UNGUARDED (2026-07-23, ndarray
+  `nars.rs` and planner `nars_engine.rs`). That row does not list this site.
+- **Open:** where the stamp lives (G5 in the entry). The guard belongs at the
+  belief store, not in the pure truth function.
+- **What closes it:** pick the stamp's home, then call `Revision` only through
+  a gate that refuses or chooses on overlap. Move P-E2's three tests onto the
+  production path; each must go red when its guard is removed.
+
+## TD-BGZ-TENSOR-INTEGRATION-TESTS-UNGATED-1 (2026-10-23) — OPEN
+
+CI runs `bgz-tensor` with `--lib` only (`.github/workflows/rust-test.yml:274`),
+so nothing under `crates/bgz-tensor/tests/` runs in CI. The crate is
+workspace-excluded, so no other step reaches it.
+
+On main `8f610a85` that directory holds 9 lab probes, 23 tests. Among them are
+P-S2 (`p_s2_compose_chain_probe.rs`, #1726), the evidence behind TORQUE row
+T-2026-10-23-1, and P-D3. Draft #1731 adds the EXO-129 probe in the same
+directory, so its PR checks would pass without running it.
+
+**Receipt:** `cargo test --manifest-path crates/bgz-tensor/Cargo.toml --tests`
+on main `8f610a85` with `CARGO_PROFILE_{DEV,TEST}_DEBUG=0 CARGO_INCREMENTAL=0`:
+207 lib tests plus all 9 integration files (3+4+2+3+2+2+2+2+3 = 23 tests), 0 failed.
+No test reads a file or an env var, so nothing blocks gating them.
+**Fix:** drop `--lib` from that step (or add a second `--tests` step). The
+step comment gives no reason for `--lib`.
+**Fruit:** Low-hanging
+**Status:** OPEN
