# Source provenance and checkpoint boundaries The initial source was extracted from Website-Backend commit b6fb23825a87412397dec703b9617148ae7eb601, subtree corresponding to this QBit. Existing license and copyright files were retained. Subsequent changes adapt the source to a standalone Maven layout; the source is preserved unfinished, not advertised as a published release. The current status and known issues document the actual validation and limitations. Local build caches, credentials, tool transcripts and machine-specific operational handoffs are excluded from the repository. Git history records the closeout snapshot. No current artifact coordinate or deployment should be inferred from a private historical build version.
