Source Document

A Source Document is a primary record, manuscript, or artifact that serves as the sole originating point for a specific chain of archival provenance within the Tower. It constitutes the material and conceptual foundation for all subsequent derivative works, analyses, commentaries, and holdings catalogued under its authority. By definition, a Source Document possesses Provenantal Integrity; its semantic and ontological status is inseparably bound to its moment and manner of creation. The identification, authentication, and custody of Source Documents are governed by the formal protocols of Source Authentication.

Definition and Criteria

According to the Seventeenth Concordance, Clause 4, a Source Document is characterized by the presence of a unique, non-replicable marking—often a Luminous Nimbus or an embedded Auditory Residue—that attests to its point of origin. More pragmatically, a document is granted Source status upon formal ratification by a panel of three senior Librarians, as per Ordinance 712-C. The ratified document is then assigned an archival signature (e.g., Sigma-9-Δ) and its location is logged in the Quarry Sigma registry. A Source Document is distinguished from a mere copy or transcript by its capacity for Property Extraction, a process by which intrinsic qualities such as latent sound or conceptual weight can be harvested for archival use.

Hierarchical Role

Within the Tower's epistemological framework, a Source Document occupies the apex of a tiered structure of authority. It serves as the definitive, non-negotiable reference for the subject it instantiates. All subsequent documents—including Concordances, Ordinances, Treatises, and derivative ledgers—must trace their lineage back to an authenticated Source. This principle of Provenant Authority is considered absolute, though its practical application is frequently complicated by contradictions between competing Sources, a phenomenon central to the ongoing Source Debate.

Physical Characteristics and Custody

Source Documents exhibit a wide variety of material forms. These include, but are not limited to: inscribed stone tablets from the lower floors, resonance-encoded Phonocylinders, folios of mutable script that rearrange themselves according to ambient light, and the so-called "quartz desiderata"—crystalline lattices that store information as refractive patterns. Regardless of form, all are housed within individual, environmentally sealed niches in dedicated Source Vaults, most notably Vault Theta on Floor 7,113. Access is strictly controlled via the protocols outlined in Determination 188, requiring a chain of physical keys and synchronized Signal Harvest from three separate custodians.

The Authentication Paradox

A significant doctrinal controversy, often cited in scholarly critiques, concerns the circularity of Source authentication. A document's status as a Source must be certified by a pre-existing authoritative document (typically a Concordance). However, that certifying document itself must derive its authority from an earlier Source, implying an infinite regress. The school of Locational Primacy argues this is resolved by the act of archival placement itself: a document becomes a Source when it is filed as one in a designated Vault. Proponents of Provenantal Integrity reject this as metaphysical convenience, insisting the Source quality must be intrinsic and pre-existing. This paradox remains formally unresolved, though it is operationally bypassed by the principle of Self-Citation employed in many foundational Concordances.

Notable Examples and Anomalies

• [[The Procurement Ledger Delta-9:]] A Source Document for all matters of unclaimed requisition. It is notable for its entries detailing tools and materials that were requested but, according to all other records, never manufactured or delivered.
• [[The Witness Ledger 44-Gamma:]] Serves as the Source for several procedural hearings. Its anomaly lies in the fact that the witness signatures it contains correspond to individuals not listed on any Tower roster, living or deceased.
• [[The Descent Protocol Delta 7 22 Practice Manuscript:]] The physical Source for the eponymous protocol. The manuscript is written on a composite material that grows incrementally heavier each time it is consulted, a property actively mined via Property Extraction for use in stabilizing unstable stairwells.

The integrity and continued discovery of Source Documents are considered the paramount archival activities. As stated in an Annex B addendum to the Fourth Concordance, "The Tower stands not on stone, but on Source; its floors are built not from rock, but from reference."
