[Protocol spec] Fix minor rendering issues
…tions/checkout-6.0.3 Bump actions/checkout from 6.0.2 to 6.0.3
A draft (modelled on ZIP 225) specifying version 6 of the transaction format for NU6.3: version 5 plus an appended Ironwood bundle, an Orchard-protocol shielded bundle committing to the Ironwood pool. Covers the v6 field layout (Ironwood bundle = Orchard bundle shape; no ZIP 233 amount and no per-input sighash info); the consensus rules (lead byte, field presence, the flag bits including enableCrossAddressOrchard at bit 2, and the no-new-value-into-Orchard turnstile rule); changes to ZIP 209 and § 4.17 for the Ironwood chain value pool balance; and the transaction-hashing changes — the Ironwood txid and auth bundle digests with their 16-byte personalizations, and the version 6 move of the Orchard and Ironwood anchors from effecting data to authorizing data. Open issues remain (the explicit fee field, the enableCrossAddress flag name, placement of the turnstile rules, and confirmation of the personalization strings).

- Title -> "Version 6 Transaction Format"; drop the fee field; coinbase empty-Orchard-bundle note; reword the Orchard/Ironwood tree/nullifier-set separation. - Sighash: extend the v6 anchor move (effecting -> auth data) to Sapling as well as Orchard and Ironwood; full txid/auth digest trees and the per-node personalization table (with _v6 personalizations where the encoding changed). - Add a "Changes to ZIP 221" section: the Ironwood chain-history MMR node fields (hashEarliest/LatestIronwoodRoot, nIronwoodTxCount) [NU6.3 onward], mirroring the NU5 Orchard fields. - Add a ZIP 209 intro citing [^zip-0209]; add the [^zip-0221], [^zip-0252], [^zip-0244-txiddigest], and [^zip-0244-authorizingdatacommitment] references. - Fix the #openissues internal anchor (MMD strips hyphens). The [0, MAX_MONEY] ZIP 209 change is left as a TODO pending the ZIP 256 update in zcash#1295.

…inology Recoverable notes are now created in the Ironwood pool (introduced by the version 6 transaction format), not directly in the Orchard pool. Retitle accordingly, distinguish "Orchard[ZSA] protocol" from the pools, and define the Ironwood/Orchard pool terms by reference to the v6 transaction format draft.

Substantial revision of the v6 transaction format draft: - Reframe around the Ironwood pool: Abstract/Motivation/Privacy Implications covering quantum recoverability, the supply-integrity motivation, the Orchard-address restriction, and the v5-vs-v6 anchor (effecting -> authorizing data) rationale; Requirements and Non-requirements reworked. - Terminology: Orchard protocol vs Orchard pool vs Ironwood pool. - Consensus rules split out; full txid/auth digest trees and the per-node personalization table. - Resolve all references: split the deployment citations into ZIP 257 (the NU6.2 deployment / vulnerability) and the NU6.3 deployment draft; add the ZIP 248, ZIP 2002, action-circuit-update, deploy-nu6.3, and ironwood-migration references; fix the action-circuit-update URL.

- Drop the "...Orchard" suffix from the flag bit names: enableSpendsOrchard → enableSpends, enableOutputsOrchard → enableOutputs, enableCrossAddressOrchard → enableCrossAddress. These bits have the same meaning in both flagsOrchard and flagsIronwood, so the suffix was misleading; add a note for the rename relative to v5. - State explicitly that version 4, version 5, and version 6 transactions are all valid from NU6.3 onward, and that the Orchard-protocol cross-address restriction is enforced for every Orchard-pool Action regardless of transaction version, so version 5 cannot be used to bypass it.

…wledgement - Add a "Note" column to the transaction-format table with †/‡/§/◊ markers for conditionally-present fields, and a legend giving each presence condition (matching the protocol spec § 7.1 convention). Move the presence conditions out of the Consensus Rules into that legend, leaving the 1:1 proofs/signatures correspondence rule. - Cosmetic improvements to the table presentations. - Acknowledge the developers of Penumbra for demonstrating the advantages of treating the note commitment tree anchor as authorizing rather than effecting data.
