Diego Rodrigues de Sa e Souza 99c6dc7fd6 Release v3.7.9 (#1917)
* chore(release): v3.7.9 — gemini-cli cloud code separation

* chore(provider): Update Jina AI model catalog (#1874)

Integrated into release/v3.7.9

* docs: update CHANGELOG for PR 1874 and retroactive credits

* fix: resolve stream defaults and codex prompt mapping (#1873, #1872)

* chore(compression): start caveman compression update

* feat(compression): expand caveman compression and analytics pipeline

Add caveman intensity levels, output mode instructions, validation, and
preview diffs across the compression pipeline.

Extend MCP and dashboard settings to support auto-trigger mode, system
prompt preservation, MCP description compression, and caveman rule
metadata. Record richer compression analytics with receipt fields,
validation fallbacks, output mode data, and add the related database
migration.

Improve preservation handling for code, URLs, markdown, math, and other
protected content while adding broad unit, integration, and golden-set
coverage for caveman parity and compression behavior.

* feat(compression): expose rule intensities and track usd savings

Add estimated USD savings to compression analytics so saved tokens can
be reported in cost terms alongside existing token metrics.

Expose caveman rule intensity metadata for settings consumers and add a
settings API route alias for rule lookup. Also preserve system prompts
when aggressive compression falls back to lite mode.

* feat(compression): RTK compression roadmap (#1889)

* chore(rtk): initialize compression roadmap branch

* feat(compression): add RTK engine and compression combos

Introduce RTK command-aware tool-output compression alongside
stacked RTK -> Caveman pipelines for mixed prompt contexts.

Add engine registration, declarative RTK filter packs, language-aware
Caveman rule loading, compression combo persistence and assignments,
analytics grouped by engine/combo, and new MCP/API endpoints for
configuration, previews, filters, and combo management.

Expose the new capabilities in the dashboard with dedicated Context &
Cache pages for Caveman, RTK, and compression combos, and update docs,
i18n strings, migrations, and tests to cover the expanded compression
surface.

* feat(compression): expand RTK DSL, filter catalog, and recovery APIs

Add RTK parity features across the compression pipeline, dashboard,
and management APIs. This expands the built-in filter catalog, adds
trust-gated custom filter loading, inline filter verification, code
stripping, smarter detection, and optional redacted raw-output
retention for authenticated recovery.

Also extend Caveman with file-based multilingual rule packs, localized
output-mode instructions, stricter preview/config schemas, engine
registry metadata, analytics fields, and broad unit test coverage for
RTK, rule loading, and stacked compression behavior.

* fix(auth): protect oauth routes and health reset operations

Require authenticated dashboard access for OAuth endpoints that can
create or import provider connections when login enforcement is
enabled.

Move `/api/monitoring/health` to the readonly public route list so
safe methods remain public while DELETE now returns 401 for anonymous
requests.

Also update Next.js native `.node` handling to avoid webpack parse
failures from external packages such as ngrok and keytar, and add
coverage for the new auth behavior.

* build(compression): ship RTK rule and filter assets with app bundles

Include compression JSON assets in Next output tracing, prepublish copies,
and pack artifact policy checks so standalone and packaged builds can
load RTK filters and caveman rule packs at runtime.

Also harden compression runtime behavior by resolving alternate asset
directories, scoping rule cache entries by source path, carrying RTK raw
output pointers through stacked runs, degrading oversized preview diffs,
and applying combo language/output mode defaults during chat routing.

Add coverage for packaging rules, provider-scoped model parsing, smart
truncate edge cases, raw output retention, and combo-driven compression
behavior.

* docs(workflows): update local repo paths to OmniRoute

Replace outdated `/home/diegosouzapw/dev/proxys/9router` references
with the current `OmniRoute` directory across deploy, release, and
version bump workflow guides so local command examples match the
renamed repository layout

* feat(compression): complete RTK parity coverage

* test(build): align next config assertions

* feat(compression): expand caveman parity and MCP metadata compression

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.

* feat(compression): unify config validation and persist MCP savings

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.

* fix(auth): require dashboard management auth for compression preview

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.

* fix(compression): preserve stacked defaults and secure metadata routes

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.

* fix(compression): align seeded standard savings combo with stacked default

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.

* docs(compression): document RTK+Caveman stacked savings ranges

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.

* fix: resolve 3 bugs — Codex tool normalization (#1914), image gen proxy (#1904), zero-arg MCP tools (#1898)

- 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

* chore(release): v3.7.9 — all changes in ONE commit

* fix: allow local ollama provider connections (#1893)

* fix(copilot): emit compatible reasoning text deltas (#1919)

* docs: update changelog and pr body with merged prs

* fix(providers): route agentrouter through anthropic endpoint headers

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

* feat(logs): show compression tokens in request log UI (#1923)

* docs: add PR #1923 to changelog
