…ows on the two design ledgers The two ledger carriers grow by appended rows, and every row was a multi-line block ending in a suffix every other row also ends in. A three-way merge never includes a shared suffix in the conflict region, so two lanes appending two independent rows get one tail below the markers for two half-blocks above them, and the correct additive resolution gives the first row's closing lines to the second. Rows are now one line each. A one-line row has no tail to lose; the only suffix a merge can factor out is the blank separator, which carries nothing. Measured, discriminating pair, gunbc built from source at d0009ca: RED byte-exact mis-resolved file -> module index refused, exit 1, "dag/gunbc/recurring_failure_mode.dag:65912-65913: expected expression, found Eq" GREEN same two-lane merge against the transformed carrier, same additive resolution -> parses, evaluates, and both appended rows render in the projected ledger. So the class is LOUD, not silent: claim_executor phase 1, the .dag parse sweep over src/v1, dag and src/v2 on the required witnesses lane, is the first phase in the job and a parse error there is a phase failure. No wall is owed and none is written. Strings carried byte-for-byte; regen writes exactly one added line to DESIGN.md and one to docs/design-ledgers.md, both the new failure-mode row.

The annotation claimed construction of the one-line row shape. That is true of the thirty rows as they stand and false of the file: nothing enforces row shape on either carrier, so one hand-authored multi-line row restores the two-line tail and the whole geometry. Writable invalid state is mechanically preventable at best, and claiming otherwise is 4b(1) rung inflation sitting in the paragraph an appender reads first. Next-rung trigger named as the capability, not an artifact: a row-shape obligation decided for every declaration of a growth-surface type. data_decl_type_facts already reads a declared type per declaration; the missing producer is one carrying each declaration's source EXTENT, sufficient to refuse a multi-line row at authoring time. Also records the complete loss-state set, all three measured at d0009ca rather than the two previously run: losing both tail lines and losing `}` alone are PARSE refusals at the module index; losing `evidence: [],` alone is a RESOLVE refusal, "missing required field 'evidence'". Nothing silent in the set. Annotation-only: projections unchanged, no regen.

A live instance of the class this branch is about: main landed mitigation_injected_where_judgment_declined (#9902) into the same append points. Because this branch had already reshaped the rows, the conflict arrived as WHOLE declarations on both sides rather than two half-blocks over one shared tail, and the resolution was additive with nothing severed. Main's row is kept, converted to the one-line shape, at main's source position; main's roster prefix is preserved and this branch's row appends after it. All 30 of main's `authored` strings carry byte-for-byte. DESIGN.md and docs/design-ledgers.md were left unmerged by the generated-artifact merge driver and are REGENERATED, not hand-resolved: generated_artifact_gate main_wet, exit 0, 35 artifacts written. Against origin/main both projections differ by exactly 1 added line and 0 deleted — this branch's one new row.

Resolves the recurring_failure_mode.dag conflict at identity grain: our one-line row shape, main's grown state_space_conflation authored bytes (#9906) carried verbatim. docs/design-ledgers.md regenerated from the merged authorities, not byte-resolved.

Closing without rebasing. This PR re-proposes content that is already on main, and following the conflict remedy would revert other lanes' work behind a green check. The content landed. #9898 squash-merged at 11:53:05Z. Verified on current Why the branch still reads as unmerged. Squash-merge carries CONTENT, not ANCESTRY — the branch's commits never become ancestors of What rebasing would have done. The report was true and its remedy was wrong. It correctly detected a stale branch and prescribed the fix for unlanded work. The "blocks merge" line is also incorrect here: no other work depends on this PR. Standing guidance for this fleet: after a squash-merge, close the auto-opened successor rather than rebasing it, and verify the landing on |
