Summary

• Align domestic WorkBuddy with the 5.9.3 request contract: runtime, baggage, ACP, stable UUIDv7 session IDs, per-attempt tracing and non-chat request IDs.
• Scope private-data and identity headers to the real account and JWT metadata, mark automated calls as auxiliary, and preserve the verified CLI and international profile differences.
• Add replay-safe gzip only to official chat endpoints: CLI and international WorkBuddy always use it, while domestic WorkBuddy uses it at 1024 bytes. Preview decodes gzip; media, search and fetch keep their original transport.
• Refresh the growth event fingerprint to 5.9.3 and update the English/Chinese behavior docs and regression coverage.

Tests

• uv run python -B -m pytest -q tests/ — 2371 passed, 2 skipped, 5323 subtests passed.

Summary by Sourcery

Align domestic WorkBuddy integration with the verified 5.9.3 client contract while preserving existing profile-specific behavior.

Bug Fixes:

• Align domestic WorkBuddy request handling with the 5.9.3 client contract.

Enhancements:

• Add profile-specific session, identity, tracing, ACP, baggage, and request-header behavior while preserving CLI and international differences.
• Apply deterministic gzip encoding to supported chat requests and decode compressed payloads in the preview service.
• Refresh WorkBuddy 5.9.3 growth-event metadata and update related documentation and regression coverage.

Documentation:

• Update English and Chinese advanced behavior documentation for the WorkBuddy 5.9.3 contract and transport behavior.

Tests:

• Expand regression coverage for profile-specific headers, stable session IDs, tracing, gzip transport, growth metadata, and compressed request decoding.

Reviewer's Guide

The PR updates domestic WorkBuddy support to the 5.9.3 client contract by revising profile and identity headers, introducing stable UUIDv7 session and per-attempt tracing metadata, and adding endpoint-scoped deterministic gzip serialization with preview decoding. Existing CLI and international behavior remains profile-specific, while growth fingerprints, documentation, and request fixtures/tests are updated for the new wire contract.

File-Level Changes

Change	Details	Files
Aligned client identity, authentication metadata, and account-scoped headers with the domestic WorkBuddy 5.9.3 contract while preserving CLI and international variants.	Bumped domestic WorkBuddy and growth-client version fingerprints to 5.9.3. Added enterprise-aware private-data headers and sanitized JWT/account identity metadata. Added domestic WorkBuddy-specific request IDs and adjusted refresh, catalog, and check-in headers. Marked automated chat and rate-probe calls as auxiliary local-agent traffic.	app/client_profiles.py app/credits.py app/buddy_task.py app/rate_measurement.py app/growth_events.py converter.py docs/advanced.md docs/advanced.zh-CN.md tests/test_identity_sync.py tests/test_credits.py tests/test_buddy_task.py tests/test_model_rates.py tests/test_growth_chains.py tests/test_catalog.py tests/test_upstream_compat.py
Implemented domestic WorkBuddy session, attempt tracing, ACP, baggage, and request-ID relationships using stable UUIDv7-shaped identifiers.	Derived stable session conversation IDs from profile, account, and session key. Generated per-attempt message/request/trace identifiers while keeping session and ACP identifiers stable. Added domestic runtime, session, ACP connection, root request, and baggage headers. Kept existing identity and tracing relationships for CLI and international profiles.	app/request_context.py converter.py tests/test_request_context.py
Added profile- and endpoint-aware replay-safe gzip serialization for official chat traffic.	Compressed all CLI and international WorkBuddy chat JSON and domestic WorkBuddy bodies at or above 1024 bytes. Restricted compression to official chat completion paths and preserved media, search, fetch, and other transport behavior. Made retries reuse identical serialized bytes and taught the preview server to decode gzip requests.	app/upstream_io.py preview/upstream.py tests/test_upstream_io.py tests/test_preview.py tests/test_region_routing.py tests/test_chat_input.py tests/test_dsml.py tests/test_message_normalization.py tests/test_nonstream_disconnect.py tests/test_reasoning_requests.py tests/test_server_tools.py tests/test_stream_failover.py tests/test_api_flow.py
