6e458d2afe [management] Move agent-network access-log ingest into the agentnetwork module (#6568)
The agent-network access-log ingest path (metaKey wire contract, flatten,
usage derivation, and the dual-write of the usage ledger + settings-gated
full row) lived in the reverseproxy accesslogs manager, even though the
agentnetwork module already owns the rest of that domain — types, read
(ListAccessLogs / GetUsageOverview), the budget-counter writes, and
retention cleanup.

Move it next to the rest: a stateless agentnetwork.IngestAccessLog(ctx,
store, entry) that the reverseproxy SaveAccessLog delegates to when the
entry is agent-network. Removes the agentNetworkTypes import from the
reverseproxy manager. No behavior change; the write/read table separation
is unchanged.

Adds real-store coverage for the disable->enable log-collection toggle
(usage ledger always written, full row gated) plus the metadata parse and
group-dedup helpers, which previously had no dedicated tests.

b763f924df [management,proxy] Reduce agent-network cognitive complexity (#6566)
Address the SonarCloud quality-gate findings in new agent-network code
by extracting focused helpers. No behavior change.

- synthesizer.go: split buildIdentityInjectConfigJSON into per-shape
  rule builders; extract mergeGuardrail from mergeGuardrails to cut
  nesting depth.
- llm_identity_inject: extract injectionEmitsAnything validation
  predicate from New.
- llm_response_parser/streaming.go: extract applyOpenAIStreamUsage and
  applyAnthropicStreamUsage (via a named anthropicStreamUsage type) and
  simplify the OpenAI scanner loop.
- reverseproxy.go: decompose ServeHTTP into serveRouteError,
  buildTargetContext, serveDirect, serveWithChain, captureRequestForChain,
  serveDeny, newResponseWriter, observeResponse, and forwardUpstream,
  preserving the defer ordering so response observation still reads the
  captured writer before it is released.

db0f5fa4f5 [management] Add agent-network telemetry metrics (#6561)
Surface agent-network adoption and usage in the self-hosted metrics
worker: distinct accounts, providers, policies, budget rules, accounts
with log collection enabled, and aggregated input/output tokens plus
cost.

Tokens and cost are summed from agent_network_request_usage (the
always-written per-request ledger) so the figures are accurate
regardless of the log-collection toggle and carry no double-counting.
All values come from a handful of indexed aggregate queries run only on
the worker's periodic tick.

Adds store.AgentNetworkMetrics with GetAgentNetworkMetrics on the Store
interface, the SqlStore implementation, and a zero-valued FileStore stub.

b416063bcc [management,proxy] Agent network: per-account LLM gateway (policy, metering, multi-provider) (#6555)
* [agent-network] Shared proto, OpenAPI schema, and generated types

* [agent-network] Management: store, manager, synthesizer, policy engine, provider catalog, HTTP/gRPC API

Adds the account-scoped agent-network module: provider/policy/budget CRUD and
store, the reverse-proxy service synthesizer, policy selection + limit
enforcement, the provider catalog (incl. Vertex AI and AWS Bedrock entries),
and the management HTTP + proxy gRPC surfaces.

* [management] Fix agent-network proxy-peer fan-out on affected-peer recompute

The affected-peers resolver loaded only persisted reverse-proxy services, but
agent-network services are synthesized on demand and never persisted. As a
result the embedded proxy peer was never folded into the affected set when a
client's group changed, so the proxy received no network-map update for a newly
authorised client and rejected its handshake until a full resync (restart).

loadProxyServices now merges the synthesized agent-network services (injected
via a registration hook to avoid an import cycle), so proxy peers learn newly
authorised clients immediately.

* [proxy] Reverse-proxy middleware framework, chain, and request plumbing

The per-target middleware chain (slots, dispatcher, mutation gate, metadata
merger), body capture, access-log terminal sink, and the proxy wiring that
builds + runs chains for synthesized agent-network services.

* [proxy] LLM parsers, pricing, and builtin middlewares (OpenAI, Anthropic, Vertex AI, AWS Bedrock)

Request/response parsers and SSE/event-stream metering, the embedded pricing
table, and the builtin middleware set: request parser, router, policy
limit-check/record, cost meter, guardrail, identity inject, response parser.
Includes the path-routed providers — Google Vertex AI (keyfile:: service-account
OAuth minting) and AWS Bedrock (bearer auth, invoke/converse/streaming, optional
/bedrock prefix) — plus the Models allowlist and unmeterable-publisher deny.

* [proxy] IPv6 in-place apply and TCP accept-loop hardening on netstack listeners

* [agent-network] End-to-end test suite, module docs, and deployment preset

* [agent-network] Fix codespell typos and exclude false positives

- labelgen word pool: vermillion -> vermilion, racoon -> raccoon.
- codespell ignore list: add flate (Go compress/flate package), recordin
  (a test-local identifier), and unparseable (a valid alternative spelling used
  consistently across identifiers + a metadata-value constant).

* [management] Set LastSeen on injected proxy peer in realstack test (MySQL strict-mode)

The injected embedded proxy peer had a PeerStatus with a zero LastSeen, which
serializes to '0000-00-00' and is rejected by MySQL in strict mode (SQLite
tolerates it). Set LastSeen to a valid time so SaveAccount succeeds on both
engines.

* [agent-network] Remove e2e shell-script suite from this branch

The end-to-end shell scripts under scripts/e2e/ are maintained in a separate
testing suite and are not part of this change set.

* [agent-network] Polish module docs: remove internal review scaffolding, fix links, verify diagrams

Strip PR-review framing, commit references, absolute paths, and stale internal
references from the agent-network module docs; fix broken relative links; verify
all diagrams against the current architecture. Remove the internal AI-reviewer
prompt file.

* [management] Refine session expiration handling to support 3-state encoding for SSO deadlines

* [agent-network] Relocate agentnetwork package to internals/modules

Move management/server/agentnetwork (and its catalog/, labelgen/, types/
subpackages) to management/internals/modules/agentnetwork, alongside the
reverse-proxy module, and rewrite all importers. Pure relocation: package names,
the synthesizer + affectedpeers registration hook, and store access (shared
store.Store) are unchanged, so no import cycle is introduced (affectedpeers
still depends only on the agentnetwork/types leaf).

* [agent-network] Co-locate HTTP handlers in the module (RegisterEndpoints)

Move the agent-network HTTP handlers from server/http/handlers/agentnetwork into
the module at internals/modules/agentnetwork/handlers (package handlers) and
rename the entrypoint AddEndpoints -> RegisterEndpoints, matching the
reverse-proxy module convention. Wiring in http/handler.go updated accordingly.
