JSON config output already carries collected config diagnostics in warnings[], so prose stderr emission must be reserved for text/local paths. Lazy permission-mode default resolution prevents an earlier config load from leaking the same deprecation before the JSON renderer runs.\n\nConstraint: ROADMAP #815 requires text mode to keep human stderr warnings while JSON config/list suppresses duplicate app-level config prose.\nRejected: Filtering all stderr in JSON mode | would hide cargo/compiler or unrelated diagnostics outside the app config warning path.\nConfidence: high\nScope-risk: narrow\nDirective: Keep load_collecting_warnings side-effect-free; use load() for human stderr emission.\nTested: cargo fmt; cargo test -p rusty-claude-cli --test output_format_contract config_json_reports_deprecations_structurally_without_stderr_duplicate_815; cargo test -p rusty-claude-cli --test output_format_contract; manual target/debug/claw JSON config fixture.\nNot-tested: cargo clippy -p rusty-claude-cli --all-targets -- -D warnings is blocked by pre-existing runtime dead_code/trident warnings.
Doctor help was already on the local help path in current source, but the exact #702 dogfood surface lacked a focused guard and the JSON help envelope was still too prose-oriented for wrappers.

Extend auto-compaction error detection to handle additional error patterns
from llama.cpp backends: 'Context size has been exceeded',
'exceed_context_size_error', 'exceeds the available context size'. Also
recover from reqwest 'error decoding response body' errors — some
llama.cpp instances return a non-SSE plaintext HTTP 500 on context overflow,
causing the SSE deserializer to fail.
Add dynamic threshold adaptation: parse server-reported context window
size from error messages (e.g., '(81920 tokens)') and set the auto-
compaction trigger at 70% of that value. This replaces the need for a
hardcoded threshold, adapting automatically to any backend's limits.
This patch was developed with assistance from OpenCode and local Qwen 3.6
API server.
Keep malformed diff invocations with trailing JSON format flags on the parser error path and lock the contract with focused output-format regressions.
Constraint: Do not touch tracked .omx state files.
Rejected: Repeating direct binary smoke loops | local auth/provider configuration intercepts those invocations and obscures parser behavior.
Confidence: high
Scope-risk: narrow

Two classifier arms had no corresponding assert_eq! in
test_classify_error_kind_returns_correct_discriminants: invalid_history_count
(both prefix and contains paths) and unknown_option (#790). Now 49/39 = full
coverage of all classify_error_kind return values.
claw '' and claw ' ' returned empty_prompt + hint:null because the
error message had no newline delimiter. Added usage hint. 61 CLI
contract tests pass.
Parity with #791 (config extra-arg fix). The plugins arg parser emitted
'unexpected extra arguments after claw plugins show ...' with no newline
delimiter, so split_error_hint returned None. Added usage hint after newline.
60 CLI contract tests pass.
