Behavior-preserving cleanup of AI-generated code smells in 5 files authored/moved by this PR:
- src/hooks/model-fallback/fallback-state-controller.ts (-47/+47 net reorganization, redundant defensiveness removed)
- src/shared/model-string-parser.ts (-4 LOC obvious-comment cleanup)
- src/shared/ripgrep-cli.ts (-13 LOC obvious comments + redundant defensive checks)
- src/tools/delegate-task/tool-description.ts (-6 LOC)
- src/tools/look-at/look-at-input-preparer.ts (-6 LOC)
Targets: obvious comments that restate code, over-defensive null checks on guaranteed values, redundant existence checks. No public API signatures changed, no type hints removed, no new abstractions introduced. Full test suite still passes.
Move the pending fallback, toast, and session-chain maps behind a shared controller initialized from the hook factory. This preserves the existing singleton semantics because exported helpers and hook instances still resolve the same lazily initialized controller while hook.ts stays under the 200-line limit.

Move parseModelString into src/shared so callers can depend on a neutral module instead of reaching into delegate-task internals.
Cross-tool coupling violates module boundaries, and this keeps call-omo-agent plus runtime-fallback from importing through a sibling tool.
Addresses review feedback on #3486:
1. claude-thinking-legacy-alias now matches both claude-opus-4-6-thinking
and claude-opus-4-7-thinking, canonicalizing both to claude-opus-4-7.
The previous diff retargeted the regex to 4-7 only, which dropped
backward compatibility for users still pinned to the 4-6 thinking
suffix.
2. MODEL_TO_CATEGORY_MAP keeps the claude-opus-4-6 to unspecified-high
entry alongside the new 4-7 entry. The map is order-independent from
MODEL_VERSION_MAP, so preserving the 4-6 key avoids relying on a
specific migration ordering for legacy agent configs.
3. Fix stale 'Claude Opus 4.6' labels and BDD test comments that the
sed-based bump missed.
Updates the canonical Anthropic Opus model in every fallback chain
(sisyphus, oracle, prometheus, metis, momus, visual-engineering,
ultrabrain, deep, artistry, unspecified-high), the unspecified-high
category default, the think-mode HIGH_VARIANT_MAP, the Claude Code
alias map, the claude-thinking legacy alias, the context-limit GA
regex, and event.ts fallback strings.
Widens supportsCachedAnthropicLimit to accept both claude-*-4-6 and
claude-*-4-7 so the 1M context cache still applies across the bump.
Regenerates the bundled model-capabilities snapshot from models.dev
and the model-fallback snapshot to match the new source output.
verification-reminders.ts was updated to use task(task_id=...) but the
'should ignore extracted session ids' test still expected the old
task(session_id=...) format, causing a consistent CI failure on dev.
Fixes the pre-existing test failure unrelated to any code changes.
GitHub Copilot proxies Anthropic's API but does not support
output_config.effort: "max" (same constraint as Anthropic OAuth).
Previously the anthropic-effort hook early-returned for github-copilot
provider, skipping all effort clamping. Users on github-copilot/claude-opus-4.6
with variant=max got HTTP 400 'invalid_reasoning_effort'.
Fix: Remove the github-copilot early return. Treat github-copilot as a
constrained provider (alongside Anthropic OAuth), clamping max→high.
Rename isAnthropicOAuth→isConstrainedProvider to reflect the broader scope.
Fixes the remaining user report from #3429.
