staleness flags

file	claim	reality	severity
docs/tips/fast-mode.md	fast mode now coexists with effort levels (v2.1.140+)	v2.1.179 is current; effort level feature is stable but interaction patterns may have evolved	low
docs/cost.md	monitor is stable as of v2.1.98+ and mature across current versions (tested through v2.1.176)	v2.1.179 is now current; bedrock/vertex AI/foundry support status unconfirmed in original doc	low
docs/tips/context-management.md	v2.1.160 removed the read-after-grep requirement for single-file grep reads	v2.1.179 is current; this feature is stable but may have received refinements	low
docs/tips/hooks-v2.md	hook behavior and available types may have evolved. consult /doctor or official docs	v2.1.179 includes only bug fixes (mid-stream drops, WSL2, sandbox glob); no hook API changes	low

proposed edits

• docs/cost.md: v2.1.179 is current stable release; no breaking changes to cost mechanics but version reference should reflect reality
• docs/tips/fast-mode.md: v2.1.179 released; confirm fast mode cost behavior unchanged for user confidence
• docs/tips/hooks-v2.md: v2.1.179 released with no hook changes; note stability for user confidence
• docs/session-workflow.md: v2.1.179 released; confirm safe mode behavior unchanged
• docs/tips/settings-hierarchy.md: v2.1.179 released with no breaking changes; update version reference for clarity

review checklist

• staleness flags accurate?
• version numbers and pricing correct?
• proposed edits read naturally?
