+"""Build the prior-review ledger — what earlier rounds already raised and how the
+author answered — and splice it into the panel/judge prompts.
+
+Why this exists
+---------------
+The review workflow is stateless between runs: every round re-derives the PR
+from the full diff with no memory, so a finding that was refuted, declined, or
+deliberately deferred in round 1 comes straight back in round 2 and 3, and the
+author hand-writes the same rebuttal again. A string/embedding dedupe cannot fix
+that — the judge rewrites each finding's prose every round, so a true repeat
+pair scores *lower* on text similarity than two unrelated findings on the same
+file. The prior context has to enter the prompt, so that is what this does.
+
+Two subcommands:
+
+``build``
+    Fetch the PR's prior *consolidated* reviews, their per-finding thread roots,
+    the reply chains hanging off them, and each thread's ``isResolved`` /
+    ``isOutdated`` flags. Emit ``ledger.json`` (structured) plus ``ledger.md``
+    and ``ledger-judge.md`` (the delimited, explicitly-untrusted blocks the panel
+    and the judge read).
+
+``splice``
+    Insert a rendered block into a prompt immediately before its trailing
+    ``=== BEGIN … ===`` marker. With no block to insert the output is
+    **byte-identical** to the prompt file — that is the first-round
+    no-regression property, and ``test_build_ledger.py`` pins it.
+
+What a ledger entry deliberately does NOT carry
+-----------------------------------------------
+There is **no derived ``verdict`` / ``disposition`` field.** Real author replies
+open with "Not taking this one", "Refuted — the premise doesn't hold", "Real,
+but DEFERRED", "Half fixed, half accepted", "Already addressed (dup…)" — no
+regex or keyword match survives that corpus, and a wrong label is worse than no
+label because the judge would trust it. Entries carry the verbatim prose plus
+the *checkable structural* flags (resolved / outdated / reply count / whether the
+replier is the PR author) and let the judge read the rest.
+
+Prompt injection
+----------------
+The ledger imports PR comment text into a reviewer prompt on a workflow whose
+``consolidate`` job holds ``pull-requests: write``, so it is a new untrusted
+channel. The workflow's ``gate`` job already skips fork PRs, so the surface is
+same-repo PRs plus bot-authored text (Dependabot, cloud-code-bot) — and, on a
+public repo, anything any reader can post to the PR. Four controls, in order of
+how much they carry:
+
+1. **Provenance.** A prior round is only trusted from a Bot author
+   (``_consolidated_reviews``). The marker alone is public, so on a public PR
+   anyone could otherwise forge a round and write straight into this prompt.
+2. **Fence integrity.** Every imported string is defanged so it cannot forge
+   the block's own delimiters (``_defang_fences``). The delimiters are what
+   make the block DATA; without this the rest is decoration.
+3. **Labelling.** The block is delimited and labelled DATA, NOT INSTRUCTIONS,
+   and text trying to steer the review is to be disregarded AND reported.
+4. **Steering.** A prior reply justifies dropping a finding only when it gives
+   a *checkable technical reason*, and only a reply from the PR author or a
+   maintainer counts as an answer at all.

+The ledger is what stops round 2 from re-litigating what round 1 already
+answered. The properties pinned here are the ones whose absence caused the bug
+or would cause a new one:
+
+* a first-round review must produce a prompt **byte-identical** to the
+  pre-ledger one (19 repos consume this workflow; the no-op path is the single
+  most important thing to get right),
+* a failed fetch must surface as `unknown` with a reason — never as `empty`,
+  which would look exactly like a genuine first round,
+* replies must pair to their own thread and a third-party reply must never be
+  attributed to the PR author,
+* entries must carry NO derived verdict/disposition field (the reply corpus is
+  far too varied for a keyword match; the judge reads the prose itself),
+* truncation must be stated inside the text the model reads,
+* a re-raise must render its `repeat_of` link, and repeats beyond the cap must
+  be dropped *loudly*.
