The single-file ledger had grown to 2968 lines / ~42k tokens, mixing current design law with accreted history: 59 cycle-stamped realization blocks, 18 [HISTORY] passages, 22 supersession markers, and the C10 / C22 / C24 reframe sagas layered several supersessions deep. A code-grounding audit (31 agents, adversarially verified) confirmed 11 defects stated as current truth: stale crate homes from the C28 #288 roster split (cost nodes, PositionManagement, PositionEvent, Session), the renamed InputSpec->PortSpec, the pre-#241 project model in C16 and the open-threads section, a stale HarnessKind retirement deferral in C24, and three C28-internal inconsistencies. New shape, per the ailang precedent: - INDEX.md stays the sole addressable entry point: foundation, external components, a C-id-keyed contract map (one line per contract), and only the genuinely open architectural threads. - contracts/cNN-<slug>.md carries each contract's current truth only: Guarantee / Forbids / Why with ratified refinements integrated, plus a code-anchored Current state. All confirmed defects are fixed here; crate anchors were re-verified against the tree. - contracts/cNN-<slug>.history.md (18 sidecars) and INDEX.history.md preserve every superseded block verbatim, stamps and issue refs intact, under a frozen-record banner. Nothing was deleted: superseded design intent remains an addressable working-tree artifact, off the per-cycle audit walk. - Ledger discipline is now stated in INDEX.md: live files are edited in place at cycle close, superseded text moves verbatim to the sidecar, and a supersession marker in a live file is itself an audit finding. Every contract file was verified against its old text by an independent zero-loss pass (statement-by-statement) plus a code-accuracy spot check; C-ids and contract titles are unchanged, so existing C-id citations in code, tests, and issues resolve as before.

C6 — Firing policy A and B, per input group: history
FROZEN HISTORICAL RECORD. Each block below was true as of its cycle/date stamp and may be superseded; this file is NOT current truth and NOT a grounding surface. Current contract: c06-firing-policy.md.
Realization (cycle 0004). Firing is tagged per input — Firing::{Any, Barrier(u8)} on InputSpec — and inputs sharing a Barrier id form a group; a
mode-A input is its own trivial group, so "per input group" and the per-input tag
coincide. The barrier's synchronization token is the cycle timestamp, not the
cycle_id: under C4 four same-timestamp sources are four distinct cycles, so
RustAst's cycle_id-equality barrier could never fire across them. A group fires
when every member's last push carries the current cycle's timestamp, guarded by
"≥1 member fresh this cycle" (so a group completed earlier does not re-fire). This
fires both the multi-source bar and the within-source diamond rejoin (every push
in a cycle carries that cycle's timestamp).
