Compendium of Spectral Liabilities

The Compendium of Spectral Liabilities is an annotated guide produced by the Descriptive Jurisprudence branch of the School. It catalogs the legal and phenomenological obligations incurred by entities operating within or adjacent to the Tower's non-standard ontological domains. Its Third Edition (issued under the Fifth Librarianate) is particularly notable for containing the opening axiom of Descriptive Jurisprudence.

Scope and Organization

The Compendium is divided into seven primary volumes, each corresponding to a major class of liability: Apparitional, Residual, Eidetic, Provisional, Contrafactual, Anticipatory, and Uncatalogued. Each volume details the conditions under which a liability manifests, the prescribed forms of discharge or compliance, and the relevant cross-references to the Concordances. For instance, the maintenance obligations for Spectral Lamplight are enumerated under Residual Liabilities, Volume II, Annex C, and are subject to the radiance limits defined in Clause 7 of Concordance 11.

Jurisdictional Authority and Updates

Amendments to the Compendium are ratified by a convocation of senior Indexers and Factotums, a process documented in the ceremonial transcripts of the Scribe branch. However, its authority is frequently contested, particularly in zones where spectral standards intersect with the material governance of the Guilds. A notable faction within the Chronurgy Guild argues that the Compendium's treatment of anticipatory liabilities fails to account for recursive Downshifting events, a dissent formally lodged in Volume Δ of the Compendium of Unheeded Dissents.

The Calibration Crisis and the Lamplight Lacuna

The most significant practical application of the Compendium arose during the period known as the Lamplight Lacuna, a systemic failure of ambient illumination protocols preceding the calibration of Spectral Lamplight. During the Lacuna, entities classified under Residual Liabilities became juridically "unmoored," leading to widespread disputes over accountability for faded inscriptions and unstable cross-references. The eventual resolution, which mandated the calibrated Spectral Lamplight now in use, was codified as an emergency addendum to the Compendium's Third Edition (Addendum 11.7).

Relation to Other Holdings

The Compendium operates in a complementary, though occasionally contradictory, relationship with several other core archival documents. It provides the liability framework for entities considered "incoherent" by the Compendium of Hypothetical Anomalies. Its standards for permissible luminescence directly inform the cultivation protocols for Luminaria Archiva Standardis, as governed by the Sixth Concordance. Furthermore, disputes over its interpretation often cite the Index of Non-Absolute Standards for precedent regarding variable applications.

Ongoing Scholarly Disputes

Primary debate centers on whether spectral liabilities are inherent or conferred. The mainstream position, as stated in the Compendium, holds that liability is conferred by the act of archival registration. A dissenting view, championed by the Guild of Formal Cartographers, argues that certain topologies of non-existence inherently possess latent liabilities, which are merely revealed by classification. This debate has practical implications for the Fade Assessment Amp Restoration protocols and the legal status of findings from expeditions to floors like Floor 4,112. No Concordance definitively resolves the issue, and conflicting ordinances are routinely cited by opposing guilds.
