FA-99716 / Chunk citation alignment / Open access

Chunk citation references remain local after bibliography compaction · case 01

Chunk citation references remain local after bibliography compaction.

ROOT CAUSE

Local reference numbers are not translated to compact global source IDs.

THE FAILURE

Local reference numbers are not translated to compact global source IDs.

Unsuccessful approach: Mapping only the first local reference leaves multiple citations partly invalid.

Case contract

Each chunk is [source_ids, local_refs]; return flattened global reference indices using first-seen unique source order.

Why this case matters

A deterministic citation bookkeeping model isolates source attribution from rendering and retrieval.

HELD IN THE MEMBER ARCHIVE

The verified repair and its recorded checks are member-only.

This mechanism has 6 recorded checks per implementation. The open-access tier publishes the failure and the unsuccessful fix; the repaired source that passes every check, and the observations that prove it, are available to members.

Every case sharing this mechanism uses the same contract and the same repair, so this one record is held back for all of them.

Member access is invitation-based. Sign in with your invited account to inspect the repair.

Verification & scope

Inputs are small integer offsets and identifiers under the stated toy contract; this does not define a document format or production citation API. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.
