docs: add empty intro and notes section wrappers

[Planeshifter]

Description

What is the purpose of this pull request?

This pull request:

• restores the empty intro and notes README section wrappers in math/base/tools/continued-fraction and math/base/tools/sum-series, the only two packages in the namespace that lack them.

Namespace summary

• Namespace: math/base/tools
• Members analyzed: 17 (no autogenerated packages)
• Majority threshold: ⌈17 × 0.75⌉ = 13 (≥76.5%)
• Features with a clear majority: file tree, package.json top-level key set, package.json field values, README section wrappers, README section order, test/benchmark/example filenames, lib/index.js banner sets, returnKind, JSDoc @returns type, JSDoc @param descriptions, @example presence, source-level dependency sets.
• Features excluded for want of a clear majority: errorConstruction (no throw site exists anywhere in the namespace); validation prologue (guard clauses present in 5/17 = 29.4%, absent in 12/17 = 70.6%); ## Notes heading text (12/17 = 70.6%); lib/factory.js and its paired test.factory.js/benchmark.factory.js (11/17 = 64.7%); test.main.js (6/17 = 35.3%).

math/base/tools/continued-fraction

Adds the empty <section class="intro">/<!-- /.intro --> and <section class="notes">/<!-- /.notes --> wrappers to math/base/tools/continued-fraction's README. 15 of 17 packages in math/base/tools (88.2%) carry both wrappers per the package-generator template; evalpoly-compile and hermitepoly ship them empty. No prose added or existing content touched; section order is now intro / usage / notes / examples / related / links.

math/base/tools/sum-series

sum-series's README.md was missing the <section class="intro">/<!-- /.intro --> and <section class="notes">/<!-- /.notes --> wrappers required by the package-generator template; 15 of 17 packages in math/base/tools (88.2%) already carry both, including evalpoly-compile and hermitepoly, which ship them empty. Both wrappers are added empty here — no prose invented, no existing line touched. The README now reads intro / usage / notes / examples / related / links, consistent with the rest of the namespace.

Validation

Checked: structural feature extraction across all 17 members (file trees, package.json key sets and values, keywords, README headings and section wrappers, test/benchmark/example filenames, source banner conventions); semantic feature extraction per package (public signature, return kind, validation prologue, error construction, JSDoc shape, source-level dependencies); and a three-agent review of every candidate correction before any edit.

Deliberately excluded, with the reason each was dropped:

• lib/main.js absent in continued-fraction and sum-series (present in 15/17 = 88.2%) — intentional. Both ship lib/basic.js and lib/generators.js and dispatch between them at load time via hasGeneratorSupport(); neither implementation is canonically "main", and both code paths are exercised by their tests.
• JSDoc @returns {string} in the four *-compile* packages (number in 13/17 = 76.5%) — intentional. These are code generators returning source strings; the contract is asserted in docs/types/index.d.ts and in tests.
• // MAIN // banner absent from lib/index.js in the four *-compile* packages (present in 13/17 = 76.5%) — intentional. Those files are bare re-exports with no statement to place under the banner; repo-wide, 292 such lib/index.js files in math/base/special carry no // MAIN // banner.
• Guard prologue in normhermitepolyf — excluded; the feature has no clear majority, and the NaN return is a documented contract shared with normhermitepoly and asserted by four tests.
• Keywords polynomial/eval/evaluate absent from continued-fraction and sum-series (present in 15/17 = 88.2%) — intentional. Neither package evaluates a polynomial; the keyword majority reflects the shared domain of the other 15.
• docs/repl.txt absent from the four *-compile* packages (present in 13/17 = 76.5%) — generator-owned artifact; out of scope.
• license field "Apache-2.0 AND BSL-1.0" in evalrational and evalrationalf ("Apache-2.0" in 15/17 = 88.2%) — legal attribution, not drift.

Disclosure

If you answered "yes" to using AI assistance, please provide a short disclosure indicating how you used AI assistance. This helps reviewers determine how much scrutiny to apply when reviewing your contribution. Example disclosures: "This PR was written primarily by Claude Code." or "I consulted ChatGPT to understand the codebase, but the proposed changes were fully authored manually by myself.".

This PR was written primarily by Claude Code. It ran an automated cross-package drift audit over the math/base/tools namespace: structural and semantic features were extracted from all 17 member packages, a per-feature majority was computed at a 75% threshold, and every candidate correction was reviewed by three independent agents before any edit was applied. Seven of the nine candidate corrections were rejected as intentional deviations and are listed under "Other" above; only the two README section-wrapper additions survived. The applied diff is 24 added lines across two README files, with no existing line modified.
