…HashTag#8884) The twenty-seventh W2 target of the CR-CHAT-04 ring tracker: the block-alignment uniformity rules - the batch ceiling, then per block the zero-id probe, the repeated-id scan, the alignment floor and the power-of-two probe, then the uniformity check against the first block's alignment - as the D5 verdict with every payload field, the original's rule order, and all ten PBAU tests transcribed plus helper and rule-order tests. The original's Option<usize> first alignment becomes the sentinel zero (the floor runs first, so every tracked alignment is at least sixteen); the original's is_power_of_two becomes a halving loop - sixty-four iterations cover every usize. The BTreeSet dedup becomes a scan over the visited blocks. Checks (conventions 0-14): t27b test 12 passed 0 failed; t27c test-report 12/12, 0 vacuous; gen-rust output compiles under rustc; coverage Untested 0; ASCII only; seal saved, all hashes MATCH;

Merge request for the gHashTag merger: steward READY (required all SUCCESS — validate, check-linked-issue, parse-ratchet, t27b-native-linux, t27b-native-macos; the red ones are non-required per Q16 and red on master too). Ledger row included; one-line rebase if the earlier lane PRs land first — I take it on request. |

Superseded by #10175: the remaining CR-CHAT targets now land as one port-wave batch per specs/policy/pr_budget.t27 (#10067/#10074), which asks for one PR per ring batch instead of one per file. The spec body, seal and ledger row in this PR are unchanged there; the batch also carries one self-consistent duplicate-body bless. Closing this one-file PR keeps the merge queue and the Actions queue small. |

Refs #8884 (CR-CHAT-04 ring tracker). Parent epic: gHashTag/trios#1812 (W2, own lane, T-PORT). Twenty-seventh W2 target delivered: the block-alignment uniformity rules — batch ceiling (1024), per-block zero-id probe, repeated-id scan ([16]u8), alignment floor (16), power-of-two probe, then the uniformity check against the first block's alignment (expected/found payload) — D5 verdict carrying idx / got / bound for every variant, original rule order, all ten PBAU tests transcribed plus helper and rule-order tests (12 total, 0 vacuous). Option first-alignment → sentinel zero (the floor runs first, so every tracked alignment is ≥ 16 — documented); is_power_of_two → halving loop (64 iterations cover every usize); BTreeSet → visited-scan. t27b 12/12 native; t27c 12/12; gen-rust compiles under rustc (0 errors, 0 &'static str, 0 Vec<const); coverage Untested 0; seal all hashes MATCH; ledger row included (pass, non-pass untouched). Dedup checked. Sequencing: one-line ledger rebase if the earlier lane PRs land first — I take it on request.
