NewMultiClient constructs a MultiClient. It does not perform network calls. projectMap maps expanded credential paths to ordered project IDs to use.

Run a command and return the result.

Close closes the underlying DB if present.

NormalizeGeminiRequest ensures roles are present.

Single-file helper retained for callers to load per-path tokens. LoadRawTokenFromFile loads a RawToken from a single JSON file path (with ~ expansion)

NewWithCAClient allows injecting a custom CodeAssist client (for tests).

WithRetries runs fn with exponential backoff w/ jitter.

computeBackoffDelay helper for tests by wrapping WithRetries timing via injection isn't trivial. Instead, check deterministic bounds with a fake RNG v

countRequestTokens approximates the total token count for the request by summing tokens of all text parts in systemInstruction and contents using tikt

doJSON posts JSON to ":<method>" and decodes the JSON response into out.

isRetryable determines if an error should trigger rotation/retry. It treats HTTP 401, 403, 429, and all 5xx as retryable, as well as common transport

ComputeTokenKey returns a stable digest for a credential identity.

DiscoverProjectID attempts to derive the Google Cloud project ID to use with Code Assist when none is provided. It mirrors the Node implementation: 1)

StreamClient returns a channel of responses and an error channel.

GetProjectID returns the project id for tokenKey, and whether it was found.

GetRRCounter returns the persisted round-robin counter for a (provider, clientID). ok == false indicates not found.

IsSupportedModel reports whether the given model name is supported.

NewOAuthHTTPClient creates an *http.Client with OAuth2 transport. If proxyURL is non-nil, it is used as the upstream proxy. Supported schemes: http, s

Open opens a SQLite database at path and ensures schema. If opening fails, a memory-only store is returned with db == nil.

SetRRCounter upserts the round-robin counter for (provider, clientID).

UpsertProjectID stores or updates the mapping for tokenKey.

Calculate SHA256 hash of a file.

Release automation for gcli2api project.

parseSSEStream is a local minimal SSE parser to avoid extra imports.

TruncateLongStringInObject recursively truncates long strings in a JSON-like object. It mimics the Python function truncate_long_strings_in_object.

withConcurrencyLimit adds simple server-wide concurrency limiting.

withRecover adds a panic recovery layer to prevent leaking stack traces and to ensure a clean 500 response is sent to the client.

Helper to force-refresh a token if it's near expiry in the next N minutes.

Flush implements http.Flusher by forwarding to the underlying ResponseWriter

MarshalJSON implements custom JSON marshaling for GeminiRequest to include unknown fields in the output

System prompt from file feature removed; no tests required.

When projectIds is ["_auto"] only, we include just one discovery-based unit.

New behavior: per-credential project units and rotation across them.

When projectIds includes the special token "_auto", include a discovery-based unit in addition to any explicit project ids.

Focused test: rotation behavior on 401 vs 500.

UnmarshalJSON implements custom JSON unmarshaling for GeminiRequest to capture unknown fields while preserving known ones
