docs(doctrine-v7): honest Putnam framing in §11 canonical-number example

[stephenlutar2-hash]

Summary

Doctrine v7 (doctrine/DOCTRINE_V7.md) lives in this .github repo (referenced by the lutar-lean README badge). Its §11 "Canonical-Number Propagation Deadline" example cited the Putnam value 83.3% (10/12) as the canonical/correct figure.

That figure counts files with structural scaffolding, not proved problems, and is itself misleading. Per the PhD Math audit:

• 0/12 Putnam 2025 problems are fully proved.
• A1, A3 are sorry-token-free but stated as → True shells.
• A5, B4, B6 carry root-level sorries on the main theorem.
• Two files previously encoded the wrong official answer (P_B6: r=1/2 vs official 1/4; P_A3: Alice vs official Bob), corrected in lutar-lean.

Change

Adds an honesty-correction note to §11. The historical example (the 1/12 staleness bug) is retained to illustrate the propagation rule, but the 10/12 value is explicitly forbidden as a progress metric.

Source verification

Official answers verified against the 86th Putnam official solutions (https://kskedlaya.org/putnam-archive/2025s.pdf): "B6. The largest such constant is r = 1/4" and "A3. Bob has a winning strategy for all n ≥ 1".

Notes

• Docs-only, single-file change.
• No canonical_numbers.json exists yet in this repo, so the doctrine doc is the authoritative location for this number.
• Out of scope this round: several coordination/ and cursor-directives/ files also cite 10/12-style Putnam numbers; flagged for a later pass.

Closed per founder directive 2026-05-30 16:23 EDT: Putnam is being dropped from the SZL story; the doctrine §11 example will be replaced with a non-Putnam example in a separate PR.
