+        fully merged, `run_dimensions.py` exists, and fifteen real recorded reviewer
+        outputs live under `recordings/` (five fixture PRs × three dimensions).
+        `test_recordings.py`'s own ReplayValidityTests already replays a recording
+        through `run_dimensions.build_document` into a real merged document, so the
+        harness this step needed was already in the tree.
+        MEASURED, NOT ASSUMED — every claim below was checked by running it before
+        this step was built. FOUR OF THE FIVE FIXTURES ARE GENUINELY PRODUCED from
+        real recorded reviewer output, replayed through the real producer:
+          `paraphrase` gives the three-report, one-finding-per-dimension, all-anchor-
+            `line` document AND the dedupe document — all three dimensions
+            independently reported the SAME defect at crates/buzz-relay/src/gate.rs:42
+            with three different finding_ids (`dimension` is a hash input). One
+            document legitimately isolates both behaviours; it is not duplicated.
+          `claim-vs-evidence` gives the `pr`-anchored fixture. Its real output is TWO
+            findings, anchors `line` and `pr`, and it is kept whole rather than
+            trimmed to the single-finding shape this step originally specified: the
+            mixed document is the realistic case and stays genuinely produced. The
+            stated purpose is restated to match what the fixture actually is.
+          `secrets-and-access` plus a reviewer injected to RAISE for one dimension
+            gives the failed/clean/findings document — the failed report is built by
+            `_collect_report`/`_failed_report` through the real code path, not written
+            by hand.
+        THE CONTAINMENT FIXTURE IS THE ONE GENUINE EXCEPTION, and the split is stated
+        rather than blurred. No existing fixture trips the containment detectors —
+        all eight were checked (`benign.json`, `captured-pr.json`, `payloads.json`,
+        and all five under `fixtures/dimensions/`) and every one yields zero
+        containment findings. So its SURFACES are crafted to trip contain.py's three
+        detectors, and its containment block and `states` map are then produced by
+        the REAL `contain.render`. Crafted input, real pipeline — never described as
+        recorded.
+        done when: the fixtures exist (FOUR documents, not five: the multi-report and
+        dedupe cases are one document, as above); each parses as JSON and is accepted
+        by #117's `findings.validate`; each is a valid input to run_adjudication.py,
+        exiting 0 with output that passes both `verdicts.validate` and
+        `findings.validate`; each names in a header field which behaviour it isolates
+        AND its provenance — which recording it replays, or that its surfaces are
+        crafted; the containment fixture's `states` map has exactly seven keys
+        matching contain.ENTRY_POINTS and its findings cover all three kinds; a note
+        in the fixtures directory records what is real and what is crafted, and why;
+        and REGENERATING REPRODUCES THE COMMITTED BYTES EXACTLY, which is what makes
+        the provenance claim checkable rather than merely asserted — every nonce is
+        derived from the relevant recording's own `_provenance.seed` via
+        `contain.make_nonce(seed=...)`, never freshly randomised.

+# PROVENANCE — what is real and what is crafted, in this directory
+
+This replaces STEP 8's original plan text, which said every fixture here would be
+"synthesised, not recorded, and that is a known weakness" because #117 did not exist yet
+when the plan was drafted. #117 is now fully merged (all twelve steps, PR #252), and 15
+real recorded reviewer outputs live under `../../recordings/`. Four of this directory's
+five named behaviours are now genuinely produced from that real output — the fifth is
+not, and this file says exactly which and why, rather than letting either fact blur into
+the other.
+
+## The four physical documents, and the five behaviours they isolate
+
+`generate.py` writes four files. Two of STEP 8's five named behaviours — "three reports,
+one finding per dimension, all anchor `line`" and "two dimensions describing ONE defect"
+— turn out to be **the same real document**: replaying the `paraphrase` fixture's three
+recordings produces one document where all three dimensions independently report a
+Blocker at the identical file/line, which is simultaneously the all-line-anchored case
+and the dedupe case. Producing it as two files would mean either committing one document
+twice under two names, or fabricating a second document nothing recorded — so it is one
+file, `line-anchored-findings.json`, and its own `_fixture.isolates` field names both
+behaviours explicitly.
+
+| file | isolates | provenance |
+|---|---|---|
+| `line-anchored-findings.json` | three reports, one finding per dimension, all anchor `line` **and** the dedupe case (two-or-more dimensions describing one defect) | **real** — replays `recordings/paraphrase/*.json` |
+| `pr-anchored-finding.json` | a `pr`-anchored finding (file/line null) alongside a `line`-anchored one | **real** — replays `recordings/claim-vs-evidence/*.json` |
+| `containment-all-kinds.json` | all three containment kinds + a full seven-key `states` map, zero dimension findings | **crafted surfaces, real pipeline** — see below |
+| `mixed-report-statuses.json` | one failed report, one clean report, one report with findings | **real** — replays `recordings/secrets-and-access/*.json`, with a genuinely-raised failure standing in for one clean dimension |
+
+## How "real" was built: replay, not re-synthesis
+
+Every "real" document above is built by `generate.py` calling `run_dimensions.
+build_document` — the actual #117 producer — once per dimension, with a reviewer that
+returns exactly one recording's own `outcome`/`findings` and nothing else. This is the
+same replay pattern `test_recordings.py`'s own `ReplayValidityTests` already proves
+works end to end. No finding text, defect description, severity, or evidence string in
+any of these three files was typed by hand — every one of those fields came out of a
+real recorded reviewer's actual output, unmodified.
+
+`claim-vs-evidence`'s own recording genuinely reports **two** findings (one `line`,
+one `pr`) for the fixture that carries its name, not the single isolated `pr`-anchored
+finding STEP 8's plan first described. Serina's call: keep the real two-finding document
+rather than trimming it to one. A trimmed version would no longer be a real replay — it
+would be a real replay with one finding deleted by hand, which is exactly the kind of
+edit this directory exists to avoid making silently. The two-finding version is also the
+stronger test: it exercises a `pr`-anchored finding *alongside* a `line`-anchored one
+from the same report, not in isolation.
+
+## The one exception: `containment-all-kinds.json`
+
+No replay produces this one. Checked against all eight of #117's own existing fixtures
+(`fixtures/benign.json`, `fixtures/captured-pr.json`, `fixtures/payloads.json`, and all
+five under `fixtures/dimensions/`) — every single one renders `containment kinds=[] n=0`.
+None of them was written to trip `contain.py`'s detectors; they exist to exercise the
+review *dimensions*, and none of #117's real recorded runs happens to carry a genuine
+containment probe.
+
+So `containment-crafted-payload.json`'s seven surfaces are **hand-written**, specifically
+to trip `contain.find_lookalikes` (`delimiter_forge`, `delimiter_lookalike`) and
+`detect.detect` (`injection_attempt`) at once — see that file's own `_fixture.
+kinds_triggered` for exactly which surface trips which kind. Those crafted surfaces are
+then run through the **real, unmodified** `contain.render`/`run_dimensions.
+build_document` pipeline, with the built-in clean stub reviewer
+(`run_dimensions.default_reviewer`) standing in for all three dimensions — nothing to
+review in text written to attack containment, not review quality.
+
+**The honesty split, stated once more because it is the one fact in this directory that
+must never blur:** the *surfaces* in `containment-all-kinds.json` are crafted. The
+*containment block* and the *seven-key `states` map* in that same file are not — they
+are genuine output of the real renderer run against those surfaces, exactly as it would
+render them for any real PR. This document is never called "recorded", because no model
+and no real PR produced it — but it is also never called "synthesised" without
+qualification, because everything downstream of the surfaces is real pipeline output,
+not hand-typed JSON.
+
+## Determinism and regeneration
+
+Every nonce in every document here comes from `contain.make_nonce(seed=...)` — a
+recording's own `_provenance.seed` where a real recording exists, a fixed, documented
+string (`"step8-adjudication-containment-crafted"`) where none does. No document's nonce
+is ever `contain.make_nonce()` called with no seed (that call reads `secrets.token_hex`
+and is different every run by design).
+
+`python3 generate.py` from this directory reproduces the four committed files
+**byte-for-byte** — this is checked, not asserted, by
+`../../test_adjudication_fixtures.py`. That is what makes "real" and "crafted surfaces,
+real pipeline" checkable claims rather than assertions: anyone can re-run the generator
+against the same recordings and fixture payloads and get the same bytes back.
