What is session-and-refresh-storage?

A local SQLite store for refresh sessions and refresh-token rotation. It records replacements and replay history for an authentication refresh engine, but is not a complete distributed authentication service.

Use it to store refresh sessions, rotate and replace tokens atomically, detect replay, enforce storage limits, and connect the store to a refresh manager.

It gives refresh handling persistent local storage while keeping issuance and ordering decisions in the refresh engine. SQLite alone does not preserve signing keys or immediately revoke already issued stateless access tokens.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00048	$0.03714
Opus 5.5	$0.00019	$0.01486
Sonnet 5.5	$0.00010	$0.00743
Haiku 4.5	$0.00005	$0.00371

Security

Grade A, and why

session-and-refresh-storage scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Session and Refresh Storage

Ownership and composition

The reference backend is plugins/session-and-refresh-storage/sqlite. It implements the compatible empty-scope tokenrefresh.Store, ReplacementStore and SessionValidator APIs, plus ManagedStore metadata, readiness and generation activation. Plain engine callers can pass sqlite.New(ctx, config) to tokenrefresh.NewManager with an empty scope. Named root/portal selection uses borrowed immutable ActiveStore views through the managed assembly contract. Importing the plugin does not register a host configuration kind. Portal sessions, OIDC grants, OAuth sessions and root runtime state retain their own storage. This is a local-host backend, not a distributed authentication service.

The refresh engine owns issuance, rotation, and publication ordering. The identity contract owns authenticated evidence and transactional current-identity checks. The embedding host must preserve its identity backend epoch and signing keys across restarts and coordinate identity changes with signing and store commit. SQLite persistence alone cannot supply those guarantees or immediately invalidate already issued stateless access JWTs.

Configuration

sqlite.Config has Path, MaxSessions, MaxRotations, and Timeout, with matching path, max_sessions, max_rotations, and timeout serialization keys. Config.Validate validates and normalizes without filesystem access. New snapshots the input; it neither retains nor modifies caller configuration.

Import the public sqlite/parser package and call NewSQLiteRefreshStorageConfigFromDirectives([]string). It accepts the complete body, one directive per encoded argument line:

path /private/authcrunch/refresh.db
max sessions 10000
max rotations 1024
timeout 1s

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
