Continuous regression suite
33-test automated suite anchored to canonical hadith (Bukhārī #1, #2, #8, #15, #7280; Aḥmad #22007) plus a 7-test cross-field consistency check. Runs on every release candidate; ship is gated on full pass.
-
NAQD adversarial framework
NAQD-1 / NAQD-2 / NAQD-3 adversarial agents stress-test grading decisions against fabrication patterns, theological subtleties, and cross-document contradictions. Findings are tracked publicly in the changelog.
-
Provenance discipline
Every record carries a `_provenanceDisclosure` block. Every grading decision carries a `verifiedBy` provenance stamp (deterministic vs LLM-assisted). External claims must cite the disclosure.
-
External review cycle
IPSC engages independent examiners on a recurring cadence to pressure-test framing, methodology disclosure, and headline claims. Reviewer feedback is integrated into the next release window.
Every release window includes recalibration items where the methodology was sharpened, a number was honestly de-inflated, or a framing element was tightened to match what the pipeline actually does. These are visible in the changelog as first-class release entries, not buried.
- v3.8
Cluster integrity rebuild
Rebuilt matn cluster taqwiyah counts to retire stale supportingChain inflation. Bukhārī sahih+hasan rate moved from 97.3% to 95.9% — an honest de-inflation, documented in the changelog.
- v3.11
Framing recalibration
Tightened external-facing framing to match what the pipeline actually does: applied AI grounded in classical rijāl methodology, structurally validated against documented teacher-student relationships, scholar-in-the-loop on residue queues.
- v3.11
Ikhtilāṭ onset backfill
11,380 onset years filled from documented sources so deterioration-period checks can run on a wider portion of the narrator graph.
- v3.11
NRS undefined-tier explicit
1,338 NRS narrator entries explicitly flagged as undefined-tier rather than silently inferred — improves downstream caller decisions.
- v3.12
NAQD-1 V1 closure
112 → 0 findings closed against the V1 NAQD-1 ruleset.
The full release-by-release timeline lives in the changelog. The authoritative provenance disclosure that ships with every record lives at /provenance.
IPSC is a computational tool, and computational tools improve fastest when they are paired with working scholars. The collaboration program runs continuously; no review queue is a backlog, it is the size of the program.
-
Open scholar collaboration
IPSC operates a scholar-collaboration program for qualified muḥaddithīn and hadith-science institutions. Collaborators inspect curated review queues, file corrections, and receive attribution in subsequent corpus versions.
-
Manuscript-collation roadmap
IPSC v3.x ships against OpenITI digital editions. Critical-edition collation (al-muqābalah) against original witnesses is a separate program of work on the long-horizon roadmap.
-
Mudallis registry expansion
Tracks 107 of ~152 narrators in Ibn Ḥajar’s Ṭabaqāt al-Mudallisīn. The remaining set requires source-text acquisition beyond the current OpenITI release window.
Qualified muḥaddithīn, hadith-science researchers, and institutional review teams: IPSC welcomes inspection, correction filings, and collaboration on the scholar-review program. Substantiated corrections are integrated with attribution in subsequent corpus versions.
