ccebabe605 Preserve verified session persistence while syncing remote runtime branch history
Origin/rcc/runtime advanced independently while this branch implemented
conversation history persistence. This merge keeps the tested local tree
as the source of truth for the user-requested feature while recording the
remote branch tip so future work can proceed from a shared history.

Constraint: Push required incorporating origin/rcc/runtime history without breaking the verified session-persistence implementation
Rejected: Force-push over origin/rcc/runtime | would discard remote branch history
Confidence: medium
Scope-risk: narrow
Reversibility: clean
Directive: Before the next broad CLI/runtime refactor, compare this branch against origin/rcc/runtime for any remote-only startup behavior worth porting deliberately
Tested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace
Not-tested: Remote-only runtime startup semantics not exercised by the session persistence change

146260083c Persist CLI conversation history across sessions
The Rust CLI now stores managed sessions under ~/.claude/sessions,
records additive session metadata in the canonical JSON transcript,
and exposes a /sessions listing alias alongside ID-or-path resume.
Inactive oversized sessions are compacted automatically so old
transcripts remain resumable without growing unchecked.

Constraint: Session JSON must stay backward-compatible with legacy files that lack metadata
Constraint: Managed sessions must use a single canonical JSON file per session without new dependencies
Rejected: Sidecar metadata/index files | duplicated state and diverged from the requested single-file persistence model
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep CLI policy in the CLI; only add transcript-adjacent metadata to runtime::Session unless another consumer truly needs more
Tested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace
Not-tested: Manual interactive REPL smoke test against the live Anthropic API

cd01d0e387 Honor Claude config defaults across runtime sessions
The runtime now discovers both legacy and current Claude config files at
user and project scope, merges them in precedence order, and carries the
resolved model, permission mode, instruction files, and MCP server
configuration into session startup.

This keeps CLI defaults aligned with project policy and exposes configured
MCP tools without requiring manual flags.

Constraint: Must support both legacy .claude.json and current .claude/settings.json layouts
Constraint: Session startup must preserve CLI flag precedence over config defaults
Rejected: Read only project settings files | would ignore user-scoped defaults and MCP servers
Rejected: Delay MCP tool discovery until first tool call | model would not see configured MCP tools during planning
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep config precedence synchronized between prompt loading, session startup, and status reporting
Tested: cargo fmt --all --check; cargo clippy --workspace --all-targets --all-features -- -D warnings; cargo test --workspace --all-features
Not-tested: Live remote MCP servers and interactive REPL session startup against external services
