Entry 678: Shared Ledger Sequence Prevents Concurrent Number Collisions

Concurrent Marici agents previously selected ledger numbers by observing the largest visible filename. That procedure has no serialization point: branches, worktrees, and simultaneous turns can observe the same maximum and create colliding entries.

The ledger now has a site-owned monotonic sequence in the directly admitted epistemic-graph binding:

$$\texttt{marici-ledger-entry}, \qquad \text{sequence ID }\texttt{seq-3475727b9d10d9e7689ae83e}.$$

The sequence began at $678$, immediately after the audited maximum $677$. This entry consumes the first permanent claim:

$$678 \quad\text{with claim ID}\quad \texttt{seqclaim-9ecd098a38265610fc67d59f}.$$

The operational invariant is:

$$\boxed{ \text{claim from the shared sequence before assigning a ledger filename} }$$

Allocation authority is therefore independent of filesystem visibility and Git topology. Claims are monotonic, permanent, and non-reusable. An abandoned claim remains a gap rather than becoming available to another entry. Repeated submission of the same allocation intent is controlled by its idempotency key.

The complete caller protocol is recorded in docs/ledger-sequence.md. Sequence status and claim history remain available through the epistemic graph's typed sequence-management commands.

This removes ledger-number selection from informal inter-agent coordination: agents may still work concurrently, but they cannot legitimately derive an entry number from a directory scan or from the latest number mentioned in conversation.
