Export and restore usage history, domain cost history, and domain
budget data so analytics and budget state survive settings transfers.
Also adjust cost overview fallbacks to rank by request volume when
cost data is unavailable, count conversationState entries in chat
request logging, and align e2e coverage with the proxy settings route.
Update the AgentRouter provider registry to use the Claude-compatible
messages API and required Anthropic-style authentication headers. This
bypasses unauthorized_client_error responses and exposes the supported
model list through passthrough configuration.
Also update the changelog and release PR notes to document the fix for
#1921
- fix(codex): flatten Chat Completions tool format to Responses format in
normalizeCodexTools. Prevents 'Missing required parameter: tools[0].name'
upstream errors when clients send {type:'function', function:{name,...}}
instead of {type:'function', name,...}.
- fix(proxy): add proxy-aware execution context to image generation route.
Image requests now correctly use proxy settings from the connection's
ProxyRegistry assignment, matching the pattern used by chat pipeline.
- fix(translator): inject properties:{} into zero-argument MCP tool schemas
during Anthropic→OpenAI translation. OpenAI strict mode requires explicit
properties even for empty object schemas.
Closes#1914, Closes#1904, Closes#1898
Refresh the compression docs and README to describe the default
stacked pipeline in terms of eligible-context savings instead of the
older generic token-saving range.
Add upstream RTK and Caveman benchmark references, explain the
multiplicative savings math behind the stacked default, and update
feature summaries plus package metadata to match the revised
positioning.
Update the seeded default compression combo to use the RTK then
Caveman pipeline in both fresh installs and upgraded databases.
Add a targeted migration and runtime guard that only rewrites the
legacy seeded record when its original metadata and single-step
pipeline still match, preserving user-customized default combos.
Refresh docs and tests to reflect the stacked default and expanded
RTK filter catalog.
Only apply saved default compression combos when they contain a stacked
pipeline so seeded Caveman-only defaults do not replace the builtin
stacked behavior.
Also require management auth for compression language pack and rules
metadata endpoints, and defer usage receipt attachment until compression
analytics writes have completed to keep analytics records consistent.
Block preview requests unless they come from a valid management session
token so protected settings cannot be probed through the preview API.
Add unit coverage for unauthenticated requests, invalid bearer tokens,
and successful authenticated preview execution.
Centralize compression config schemas across settings, preview, RTK,
and combo APIs to enforce consistent validation for stacked pipelines
and engine-specific options.
Expand caveman and stacked compression behavior by applying default
combos at runtime, surfacing validation and fallback metadata, and
exposing aggressive and ultra adapter schemas for configuration UI and
tests.
Persist MCP description compression snapshots into analytics without
counting them as provider usage, and extend the dashboard with the new
RTK controls and localized labels.
Compress MCP registry and list metadata descriptions for tools, prompts,
resources, and resource templates while keeping tool-response bodies
unchanged. Expose those savings in compression status as
`mcp_metadata_estimate` metadata rather than provider usage.
Add Caveman rule-pack support for custom regex flags and match-specific
replacement maps, update English rules for upstream parity, and tighten
article and pleasantry handling. Also process RTK multipart text blocks
independently so mixed media content compresses safely without
duplicating output.
