Monsoon mortar
Status is derived only from the shepherd-authored triage/prediction data above -- community submissions and claims are a separate overlay and can never change it (see the participation panel below).
Claim (verbatim)
Monsoon mortar. The Swahili stone towns of the East African coast — Kilwa above all — were built of coral rag set in lime mortar, and construction there was governed by the monsoon: the rains halt building and lime-burning, so work proceeds in an annual pulse tied to the dry season. Mortar is not homogeneous stuff; each season's batch differs subtly in lime chemistry, aggregate and curing conditions, much as a tree's summer and winter wood differ. The conjecture is that Swahili coral-stone walls should therefore show annual lime-mortar banding locked to the monsoon building season — visible in mortar micro-stratigraphy as compositional or textural layers, one per building year. If so, a wall at Kilwa is an incremental climate archive: its bands count construction seasons and record the rainfall regime under which each was laid, architecture doing the work of a sediment core.
Prediction clause (verbatim)
For sampled wall sections at Kilwa, prepare mortar micro-stratigraphic thin sections and log compositional and textural layering; independently estimate each section's construction span from architectural phasing and dating. Primary clause: periodic banding is detectable in a majority of sampled sections, and in independently dated sections the band count matches one band per building year to within plus or minus 20% of the architecturally estimated construction span. The verdict follows the primary clause.
Kill-dataset (verbatim)
mortar micro-stratigraphy at Kilwa.

Nobody has run this test. The kill-data is named above. If you can run it — or you know the paper that already settles it — claim the kill or submit the prior scholarship. Kills and prior scholarship are credited here, by name, as they come in.

Provenance
Run: Imported conversation (verbatim harvest) · model: claude-fable-5
Origin: operator conversation with Claude Fable 5 at max effort, conducted 2026-07-03, relayed verbatim by the operator into the shepherd session on 2026-07-04. No ModelRun exists for the original generation (it happened outside the pipeline); this transcript file is the canonical capture. Transcript path: docs/generated/conjecture_harvest_fablemax_20260703.md. Model (operator-attested, not pipeline-recorded): claude-fable-5. Novelty disclaimer (verbatim, load-bearing -- rule 4): "Same caveat as before, doubled: at 100 items across all of archaeology and history, some of these will have cousins in the literature I can't check. What I can guarantee is the format — each links two things not normally linked, and each names the dataset or measurement that would kill it."
Novelty / leakage triage
no prior formulation located (search dated 2026-07-05)
Kilwa's coral-stone/lime-mortar construction, mortar radiocarbon-dating methods (limekiln-fuel entrapment), and seasonal growth-banding in living coral all exist as separate literatures, but no source was located examining micro-stratigraphic banding within construction mortar tied to monsoon building seasonality. No prior formulation located (search dated 2026-07-05) — one of the dossier's blank-join items.
