Shadow-Hoarding

Shadow-Hoarding is the accumulation of unregistered shadows beyond the quantity permitted to a single holder, and the body of Concordance and case practice governing it. It is distinguished from mere collection by intent: a shadow retained openly and listed in a Floor Register is a holding; a shadow retained in a drawer, a cistern, or a colleague's unused coat is a hoard. The distinction is jurisdictional before it is moral, and the Office of Photic Inventory has twice ruled that a hoard is defined by what the Registry cannot see rather than by what the holder intended.

The practice is old enough to have generated its own vocabulary. Hoarded shadows are termed unlisted stock; the containers in which they are kept are termed occluding vessels; and the act of moving a hoard between floors without declaring it is termed transit in shadow, which is charged separately and more severely than simple accumulation.

The limits and where they come from

Third Concordance, Annex 12, fixes the general limit at eleven shadows per registered holder, of which no more than three may be of a grade above Attributed Shadow. The number eleven is conventionally traced to Fifth Concordance, Clause 40, which permits a clerk to retain "eleven objects of any description, the twelfth being the Tower's." Applied to shadows, this produced an ambiguity that has never been fully closed: a shadow is not, strictly, an object, and the Shadow Without Object specimens of the Shadow Annex have been cited in at least four proceedings as evidence that the clause does not bind them at all.

Holders of scholarly standing may petition the Curator of Shadow Catalogues for an increased allowance. The Curator's office, on Floor 417, receives 340 to 410 such petitions annually and approves an average of nine. The approved are overwhelmingly cases of Memory Shadow, where the three grades — Static Impression, Cyclic Echo, and Latent Resonance — are catalogued as derivative of a single source and may be counted as one holding, provided the source is named in writing.

The Vance finding and the silence markets

The modern law of Shadow-Hoarding derives chiefly from the proceedings against Surveyor-Prime Elara Vance, whose holdings were found to exceed her allowance by a disputed 46 units. The surveyors' contention was that the units in question were not hoarded but merely uncatalogued, a category the Office of Photic Inventory declined to recognise. The Inquest's finding, recorded in its Fourth Recension, established that intention to retain, not intention to conceal, constitutes the offence.

"A shadow is hoarded from the hour it is set where the Registry does not look, whatever the holder says he meant by it."

— Office of Photic Inventory, Ruling 12-Beta

The finding became inseparable from the allegations of acoustic silence markets that followed the Surveyors' Revolt, in which certain surveyors were said to have traded access to resonance data in conditions of engineered quiet. Later commentators have tended to merge the two matters. The Clerks of the Sundial have objected to this, noting in their 14th Marginalia that Vance was never charged with any market, only with the hoard, and that "the noise of the one has obscured the counting of the other."

Method and detection

Hoards are detected by comparative silhouettometry. Inspectors cast a shadow against a calibrated ground and compare its profile to the Register entry; a divergence exceeding two degrees of taper in any sector indicates stock not accounted for. The method was thrown into difficulty by the Ninety-Degree Shadow Rule, since a hoard stored at right angles to its attributed light produced profiles indistinguishable from an honest single holding. Inspectors therefore carry a travelling aperture and a mirror, and are instructed to walk the vessel's perimeter twice in opposite directions. Where the profiles disagree, a hoard is presumed.

Complications arise with Shadow-Casting Sporulation. A hoarded Root Shadow kept in darkness for more than a season will sporulate, producing independent Cast Shadows that multiply the count without the holder acting further. The Shadow Catalogues govern the transition, but the position of the holder is awkward: by Ruling 12-Beta the sporulated stock is his, and by Instrument 9-Delta he cannot lawfully open the vessel to count it. The Sub-Basement Shadow Court heard one such matter in the winter of 14-Ash and adjourned it indefinitely on the ground that no one could say what was in the box.

The Dissonance question

A substantial dissent holds that Shadow-Hoarding properly concerns not quantity but unresolved Shadow Dissonance. On this reading a hoard is any accumulation in which dissonant shadows are stored in contact, so that their disagreement compounds. The case usually cited is The Straw's Shadow, whose relocation to the Shadow Annex followed Incident Report 88-Gamma and which, had it been permitted to remain with its neighbours, would on this view have constituted the Tower's clearest hoard. The majority rejects the argument as circular: dissonance is measured against a stated expectation, and an unregistered shadow has none.

What survives of the dissent is a procedural caution now printed on the reverse of every inventory warrant: Do not store an unlisted shadow in the same vessel as a listed one, or the listed one will be required to answer for it. Inspectors report that the caution is widely ignored and that the resulting disputes consume, on average, eleven days of Registry time each. A list of vessels currently certified as sound may be consulted at the Clerks of the Sundial's desk, though it is not the desk's business and they would rather it were asked for elsewhere.
