+    `docs/reviews/<task>-verification.json` and the second component uses
+    `docs/reviews/<task>-db-verification.json` (or `-indexer-`). Both carry the
+    same review `git_sha`. Check both after merging, and run each merged
+    feature's acceptance suite as the independent check.

+34. **Soft Gherkin mutation survivors from weak text assertions.** For
+    `txid-wire-encoding.feature` the survivors were single-character case
+    mutations of carried text (`message`/`option`/`comment`) that no scenario
+    asserts (the scenarios assert the Memo prefix and the referenced txid).
+    For `repair-txid-encoding.feature` the survivors were mutations of
+    `reversedPostTxid` in the negative "contains 0 entry whose key starts
+    with ..." assertions: the key is absent by construction, so any mutated
+    value still yields 0. Both are intrinsic equivalents (gotcha #12 class),
+    not implementation gaps; the wire-order and positive-repair mutations were
+    killed (14 executed/8 killed and 21/18).

+- **Txid wire encoding repair (2026-09-16):** fixed the endianness bug that
+  broke every like, reply, poll option, and poll vote broadcast by
+  psf-memo-client. The client embedded the referenced txid in big-endian
+  display order while the indexer expected little-endian wire order
+  (`txHashFromPush` reverses it), so the indexer stored a byte-reversed
+  reference that never matched the post/poll: like counts read 0, replies
+  vanished from threads, and poll options/votes detached. `hex.js` now owns
+  `txidToWireBytes`; `buildTxidTextPayload` reverses the txid, and the
+  reply-only `buildReplyPayload` was replaced by that shared helper. Added
+  `psf-memo-db/src/lib/repair-txid-encoding.js`
+  (`correctReference`/`repairTxidEncoding`) and the
+  `psf-memo-db/util/txid/repair-txid-encoding.js` CLI to rewrite existing
+  reversed references in `likes`/`postLikes`, `postParents`/`postChildren`,
+  `pollOptions`, and `pollVotes`, using `posts`/`polls` existence to keep the
+  correct orientation, leave unknown targets alone, and stay idempotent. The
+  20-byte hash160 follow/mute path is unchanged. Client + DB. Specs:
+  `psf-memo-client/specs/txid-wire-encoding.feature` and
+  `psf-memo-db/specs/repair-txid-encoding.feature`. Merged to `master` at
