Merge the two independent 2026-09-05 drafts under history/ into a single
normative specification at spec/PqrstEstimationPractice.md (v0.1).
Where the sources diverged on the canonical result format, the block/
signature record is adopted as the source of truth and the per-dimension
table is retained as an optional presentation form; recorded in the spec's
version history. Two rules the sources implied but did not state are added:
confidence stays outside the 5-tuple (R9), and no sixth dimension may be
introduced (R10).
Add PqrstPrompt.md in the root as the canonical end-of-session prompt,
pairing the fuller rule list with the strict fixed output block.
Add INTENT.md and SCOPE.md framing the repo as the means of closing
agentic coding sessions: why the practice exists, its anti-goals, and the
boundary that this is a specification-and-prompt repo only — no tooling,
storage, harness integration, scoring, or empirical validation.
Source drafts under history/ are retained unmodified and are append-only.
