Finding
Floor shift
The later low-end behavior reaches territory that previously looked like the upper band.
Signal
Baseline, not spike
Centers the raised lower bound, not only the highest-performing examples.
Bridge
Solo to launch
Connects the controlled solo signal to the broader launch-phase pattern.
Evidence Frame
What happened
PRM’s later sections do not merely produce higher maximums. They raise the low end, the center, and the general operating band.
That is what makes the finding stronger than a simple spike. A spike says one part reached upward. A raised floor says the system’s ordinary operating level moved upward.
What “floor” means here
In this context, floor does not mean the weakest individual line or a private source excerpt. It means the lower band of aggregate slice behavior under the tested measurement lenses.
The public-safe claim is about measured blocks, not quoted text. If later slices keep their lower band above earlier high-water behavior, the result points toward system-level evolution rather than one impressive passage.
Why it matters
A maximum can be a burst. A higher average is stronger. A higher floor is stronger still.
When the floor rises above an older ceiling, the result suggests system-level evolution rather than isolated improvement.
This is the bridge between the Solo Dataset and Launch Phase. Solo provides the chronological structure. Launch Phase shows the final-third acceleration. New Floor Above Old Ceiling explains why that acceleration matters: it changes the baseline.
Public-safe interpretation
The public page treats this as an aggregate finding. It can describe the relationship between earlier and later PRM blocks, and it can show the chart family that supports the raised-baseline interpretation.
It does not publish protected writing, private file manifests, source-level mappings, third-party source labels, artist names, album titles, song titles, or line-level examples.
What this page proves / does not prove
This page supports a public-safe aggregate claim: the later PRM operating band rises above earlier high-water behavior under the displayed measurement lenses.
It does not publish source text, expose private maps, or claim that one writer is universally better than another. Reference comparisons are baseline coordinates for interpreting metric behavior, not artistic rankings or claims of superiority over other artists or corpora.
How to read the charts
Start with floor / center / peak. It is the clearest public visual for the claim because it separates the low band, center band, and high band across tested slices.
Then use the metric-delta chart and heatmap to see whether the later movement appears across the wider metric surface. Stability checks whether the result holds across measurement windows. Raw metric trends provide the large-window context behind the aggregate finding.
What this result means
New Floor Above Old Ceiling is a baseline claim. It says the later PRM system is not only producing better peaks; it is operating from a stronger lower band.
For the site narrative, this page keeps the claim precise. The Sequel is the broad half-corpus separation. Launch Phase is the final-third apex inside that later half. New Floor Above Old Ceiling is the raised-band interpretation that links those two findings.
Public-safe boundary
Public pages show aggregate evidence, metric behavior, method provenance, and corpus structure. Protected text, identities, source titles, and reconstructable mappings stay private.
