-#    ironwood line the confirmed-working reference wallet **zcash-devtool** builds against. This is a
-#    **plain upstream pin: zecd no longer carries a librustzcash fork.** (Previously it pinned
-#    `zecrocks/librustzcash` = this rev + one cherry-pick, "Backfill received-note memos for own
-#    self-sends". That cherry-pick was DROPPED here to move off the fork - see below - and is being
-#    submitted upstream separately.) The ironwood leaf crates are published to crates.io as release

+# Still-relevant notes inherited from the git-pin era (they describe the published line too):
 #
-#    **Dropped cherry-pick - self-send memo backfill (fe9c4144).** It added a `zcash_client_sqlite`
-#    `put_blocks` pass that re-decrypts the wallet's own mined txs to fill a received note's NULL memo:
-#    a shielded self-payment is a `Recipient::External` (no received note at send time), the block
-#    scanner later creates the note with a NULL memo (compact outputs carry none), and enhancement
-#    skips the wallet's own txs (raw pre-stored → Status-only). The regtest suite showed this gap is
-#    **narrow and self-healing**: the live mempool path fills the memo on the authoring node in the
-#    common case, and a from-seed restore (no pre-stored raw → enhancement runs) recovers it - so it
-#    only bites the *authoring* node when the mempool missed its own self-send, and a rescan fixes it.
-#    Guarded by an ironwood-tier regtest that forces the block-scan-only path (send → stop → mine while
-#    down → restart same datadir); that test FAILS on this fork-free pin and PASSES with the cherry-pick,
-#    which is why it lives on a branch that carries the fix. Once the fix merges upstream, bump the rev.
-#    Not carried either: the create_pczt Ironwood-build (librustzcash#2543) - upstream
-#    `create_pczt_from_proposal` at this rev still rejects Ironwood PCZTs (`step_uses_ironwood`), so
-#    zecd routes **Ironwood sends through the fused `create_proposed_transactions` path** via the
-#    `ironwood_forces_fused` gate in `actor.rs` (~4.5 s/send keygen; drop the gate to reclaim the PCZT
-#    cache once upstream removes its guard).
-#    The upstream line carries the rest of the ironwood API zecd uses: ironwood receive **memos**
-#    (`decrypt_transaction` decrypts the Ironwood bundle), `ironwood_balance`, `Note::pool()`, the
-#    ironwood `ChainState`, and (for the fused send path) native Ironwood build+prove. NB the line
-#    pins **orchard `0.15.0-pre.2`** and needs the explicit-checkpoint-retention **shardtree** APIs plus
-#    a `clear_flags` checkpoint-pruning panic fix, so shardtree + incrementalmerkletree are git-patched
-#    below to **upstream `zcash/incrementalmerkletree`** (main, rev `7b23adb6`) - also not a fork.
+# - **Self-send memo backfill is NOT in this line.** A cherry-pick (submitted upstream separately)
+#   filled a received note's NULL memo for the wallet's *own* mined self-sends via a `put_blocks`
+#   re-decryption pass. The gap is narrow and self-healing (the live mempool path fills the memo on
+#   the authoring node; a from-seed restore recovers it via enhancement) - it only bites the
+#   authoring node when the mempool missed its own self-send, and a rescan fixes it. Re-check when
+#   bumping to the next RC/final.
+# - **Ironwood sends route through the fused `create_proposed_transactions` path** via the
+#   `ironwood_forces_fused` gate in `actor.rs` (~4.5 s/send keygen). NB the published RC now BUILDS
+#   Ironwood PCZTs (librustzcash#2543 landed - the old git rev rejected them), so the gate is a
+#   conservative choice, not an upstream constraint; drop it (and reclaim the PCZT proving-key cache)
+#   once the cached path is validated against an NU6.3-active chain.
+# - **Single-pool-group input selection** (upstream `00c789f9`): shielded inputs come from one of
+#   two mutually-exclusive groups - {Orchard} or {Sapling+Ironwood}, never mixed - the NU6.3
+#   migration model (past NU6.3 a new Orchard-address output becomes an ironwood V3 note, so Orchard
+#   V2 is a legacy drain-only pool). Applied *unconditionally* (pre-NU6.3 too), so the default
+#   (NU6.2) build no longer combines Sapling+Orchard inputs in one transaction; the `regtest_sapling`
+#   e2e was updated to the turnstile model to match.
+# - **Ironwood model** (matches devtool): ironwood notes are **Orchard V3 notes** - same key tree,
+#   same key derivation, scanned by the existing Orchard path, stored in `ironwood_received_notes`
+#   and surfaced in `v_received_outputs` with pool code 4; balances roll up via
+#   `AccountBalance::ironwood_balance()`. **Sends**: the proposal auto-routes Orchard payment/change
+#   into the ironwood bundle past NU6.3, and the prover adds an ironwood proof step
+#   (`requires_ironwood_proof`/`create_ironwood_proof`) using a `PostNu6_3` proving key (see
+#   `actor.rs`; mirrors devtool's `pczt/prove.rs`).
 #
-#    This rev **includes `00c789f9`** ("Select shielded inputs from a single pool group"): shielded
-#    inputs are selected from one of two mutually-exclusive groups - {Orchard} or {Sapling+Ironwood},
-#    never mixed - the NU6.3 migration model (past NU6.3 a new Orchard-address output becomes an
-#    ironwood V3 note, so Orchard V2 is a legacy drain-only pool). It is applied *unconditionally*
-#    (pre-NU6.3 too), so zecd's default (NU6.2) build no longer combines Sapling+Orchard inputs in one
-#    transaction; the `regtest_sapling` e2e was updated to the turnstile model to match (fund Orchard
-#    2 ZEC / Sapling 1 ZEC; a 1.5-ZEC payment to the Sapling receiver draws the Orchard group and
-#    produces an Orchard->Sapling turnstile). We accept this to stay lock-step with devtool/upstream.
-#    A `[patch]` git-workspace must be all-or-nothing (a git crate's path-siblings would otherwise
-#    conflict with the same crates.io versions), so the whole librustzcash set is pinned to this one
-#    rev. `[patch]` is global (cargo can't feature-gate it), but upstream exposes the ironwood types
-#    unconditionally (no `cfg(zcash_unstable = "nu6.3")` gating remains upstream), and NU6.3 stays
-#    inactive without the `ironwood` cargo feature, so the default build is released-equivalent.

-#    Ironwood model at this rev (matches devtool, differs from the old valar fork): ironwood notes are
-#    **Orchard V3 notes** - same key tree, same key derivation, scanned by the existing Orchard path,
-#    stored in `ironwood_received_notes` and surfaced in `v_received_outputs` with pool code 4;
-#    balances roll up via `AccountBalance::ironwood_balance()`. **Sends**: the proposal auto-routes
-#    Orchard payment/change into the ironwood bundle past NU6.3, and the prover adds an ironwood proof
-#    step (`requires_ironwood_proof`/`create_ironwood_proof`) using a `PostNu6_3` proving key (see
-#    `actor.rs`; mirrors devtool's `pczt/prove.rs`). Bump this rev (and the crates.io `-pre` version

-#    (intentionally - would ship unreleased WIP into reproducible images).
