docs(knowledge): align model-matching table with dateless model-ID scheme

[kyle-sexton]

No linked issue.

Summary

Doc-alignment campaign row 228 ("Model IDs and versioning",
https://platform.claude.com/docs/en/about-claude/models/model-ids-and-versions).

The Anthropic profile's digest-agent model-matching table pinned model-specific guides to
"a full model ID — never a bare family alias, which resolves to the current family model".
The live page now documents that since the 4.6 generation the canonical model ID is dateless
(claude-{name}-{major}[-{minor}]) and "is not an alias. It is the snapshot" — so the old
wording would misclassify exactly the correct pin for a current-generation model guide as a
forbidden alias and wrongly fall through to the session default.

Changes

• Reword the table cell to "its pinned model ID — never an alias that can move to a newer
  snapshot", dropping the stale dated-era vocabulary.
• Add one sentence under the table routing the generation-dependent pinned-vs-alias
  resolution to the live page at spawn time (pointer-not-copy — no model-ID tables copied).
• Bump knowledge plugin 0.10.21 → 0.10.22 with changelog entry.

Evidence

• Live fetch 2026-08-04, raw-markdown channel (.md appended), 3836 bytes / 83 lines,
  channel re-verified working for this doc.
• Page: "This guarantee covers model IDs, not the convenience aliases that the Claude API
  accepts for some earlier models" (pinning guarantee); "A 4.6-generation ID such as
  claude-sonnet-4-6 is not an alias. It is the snapshot" (drift trigger).

Review: docs(knowledge) — align model-matching table with dateless model-ID scheme

• Gather context (diff, changed files)
• Understand the request
• Review changed files
• Post findings

Scope reviewed: plugins/knowledge/.claude-plugin/plugin.json, plugins/knowledge/CHANGELOG.md, plugins/knowledge/skills/docpage-digest/context/anthropic-docs-profile.md (per git diff origin/main...HEAD).

Summary

Straightforward, well-scoped doc-alignment change. No code logic involved — this is a prose/table wording fix plus a pointer sentence to the live model-IDs page. I don't have findings that need fixing.

Notes (no action required)

• Version bump correctness: 0.10.21 → 0.10.22 patch bump in plugin.json is consistent with the CHANGELOG entry and CLAUDE.md's "version is the delivery vehicle" rule — good.
• Pointer-not-copy discipline: the new sentence in anthropic-docs-profile.md#L179-L182 correctly routes generation-dependent resolution to the live page rather than embedding a model-ID table snapshot in the profile — matches this repo's stated anti-staleness pattern and avoids re-introducing the exact drift this PR is fixing.
• No duplicate references: confirmed the model-ids-and-versions URL only appears once in the file, so this isn't creating a second inconsistent copy of the same guidance elsewhere.
• Table cell wording (line 175) reads correctly — antecedent of "which would digest a historical guide on the wrong version" resolves unambiguously to "an alias," and the "When no pinned ID is resolvable, omit the override" fallback still matches the row's original intent.
• Fresh-docs mandate: PR body cites a live fetch (2026-08-04, raw-markdown channel, 3836 bytes) with two direct quotes from the source page as evidence for the "dateless ID is the snapshot" claim — satisfies the sourcing requirement for this class of change. I can't independently re-fetch the page in this review, so I'm trusting the cited evidence as presented.
• Out of scope for this lane: no security-relevant surface (no manifest/hook/MCP contract change, no code execution) — nothing to hand off to the security lane.

Security Review — PR #1928

• Fetch PR diff / read changed files
• Assess for logic flaws, injection, secrets handling, workflow permission changes
• Post findings

Scope: plugins/knowledge/.claude-plugin/plugin.json (version bump 0.10.21 → 0.10.22), plugins/knowledge/CHANGELOG.md (+15 prose lines), plugins/knowledge/skills/docpage-digest/context/anthropic-docs-profile.md (+6/-1, table-cell reword plus one routing sentence).

(Note: git fetch/gh pr diff were blocked by sandbox approval in this run, so I read the three changed files in full on the PR branch directly — diffs are small enough that full-file review gives complete coverage of what changed.)

Findings

No security issues found.

This is a docs-only change:

• No workflow files (.github/workflows/**) are touched, so no permissions:, trigger, or pull_request_target/workflow_run changes are in scope.
• plugin.json's only change is the version field bump — no new userConfig keys, no permission or capability widening, no new MCP/tool wiring.
• CHANGELOG.md is inert prose.
• anthropic-docs-profile.md is a static, maintainer-authored context file bundled with the plugin (not fetched from an untrusted runtime source), consumed as instructions by the docpage-digest skill's agent. The edit rewords one table cell and adds a sentence pointing to a first-party platform.claude.com URL — no user-controlled input, no new external fetch target, no secrets/tokens/credentials touched, no shell/script/template content introduced.

Nothing here creates a new injection surface, alters trust boundaries, or changes what code executes.
