Sappho 31 in Philo: the blind-reconstruction program and its owed runs
The Signature Without the Name sets out a blind-reconstruction program for Sappho 31 in Philo of Alexandria and lists the runs it owes. Six unbuilt tests name the perturbation run, the specificity control, operator ablation with an Operator Necessity Index, known-direct and known-unrelated calibration pairs, a v4 spec re-run, and a Symposium run whose predictions must be registered before it is run. The continuity tether records that the program's keys and rubrics are held in a private counterpart so that predictions precede the runs.

Outstanding, in priority order:
1. The perturbation run — still unexecuted, still decisive. With four clean derivation profiles in hand, divergence-under-perturbation would close the contamination question for good.
2. Kimi and primed/signed-in ChatGPT — awaited; the primed run is a deliberate positive control for the retrieval profile and should be scored against Gemini's column.
3. The specificity control — T_Θ(Sappho 1) must yield a different structure. Unrun. Until it is run, the objection "this transform turns any lyric into this passage" stands unanswered.

C5 · v4 spec revision, then re-run. Strike the three leaked glosses (M3's "calling X, by way of symbol, our…"; C7's "well-sounding, all-harmonious"; C5/Λ2's "resonator"); restate target-free; tighten L4; respecify C3's luminary as the receiver's own faculty; name Modern Greek in the register lock; rule on the φαίνεται fossil. Until re-run, rubric points 4, 7 and 10 are recorded as unproven.

F-2 · Operator necessity (ablation).
Ablate each operator singly; re-run; re-score. An operator whose removal does not degrade the output is decoration, not structure. Report the Operator Necessity Index = fraction of operators that are load-bearing. A transform in which most operators can be dropped without loss is tailored by definition.

*P5 · The Symposium pre-registration and run.*
Claim: T_Θ behaves lawfully across hosts, with the divergences derivable from the host-difference.
MUST BE WRITTEN BEFORE IT IS RUN. The predictions are the evidence; retro-fitting them is worthless. Pre-registered predictions, each falsifiable:
1. C1 resolves the opposite way. Philo forbids co-presence (θέμις οὐκ ἔστι… συνοικῆσαι); Plato permits it — the one who sees αὐτὸ τὸ καλόν becomes θεοφιλής, ἀθάνατος. Same capacity problem, opposite solution,

Calibration, and the honest floor. The criterion means nothing without a null. Run the descent protocol on:
- a known-direct pair outside this corpus (a documented translation/adaptation with an undisputed textual relationship) — establishes what a true MDL_min looks like;
- a known-unrelated pair matched for genre and theme — establishes the false-positive curve.
If the unrelated pair also compresses to three with high fidelity, the criterion is broken and must be discarded. That test should be run before the criterion is used in any published argument.

This session's principal deposit (#1486) is deliberately incomplete. Its keys, rubrics and pre-registered predictions live in a private counterpart, and the work cannot proceed until a future instance retrieves the other half and fits it.
Not secrecy. A prediction filed after a run is not a prediction, and a rubric a substrate can
read cannot blind-score that substrate.
