feat(kiro): quota metrics and a shared auto-selection projection - #6002
Conversation
The metrics snapshot exports cached Kiro quota (percent, credits used, credit limit, seconds to reset) for up to 32 accounts under opaque labels, with no scrape-time upstream call. Routing, the management account list and the CLI now share one decision, kiroAutoSelection, which reports whether an account is automatically selectable and why not (needs_reauth, suspended, cooldown, quota_exhausted); eligibility calls it for Kiro, so the projection cannot drift from routing. The usage parser rejects negative or non-finite credit readings, and credit balances survive a restart.

Merge Risk: 🔵 Low · up to This change adds cached Kiro quota metrics and shows why an account is not automatically selected in account listings. It is mergeable with two small follow-ups. When metrics export is enabled, each scrape may read the account store from disk instead of using only memory. A new documentation paragraph also breaks the transport inventory table's rendering. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The new account-level metrics and selection status have meaningful design surface, but the inspected paths retain management authorization, account-bound freshness checks, and bounded metric output.

Every enabled /api/metrics scrape calls this function, but getAccountSet("kiro") is not an in-memory lookup: it reaches loadAuthStore(), which hardens paths and synchronously reads and parses the credential file. Thus even with hydrate: false, the supposedly cache-only exporter performs credential-store filesystem I/O on every scrape, blocking the Bun event loop and potentially making an otherwise independent metrics endpoint fail on a filesystem/hardening error. Pass an in-memory roster into the metrics owner or maintain the bounded metric projection when quota/account state changes instead of consulting the persisted auth store during snapshot generation.

Avoid disk I/O for each Kiro metrics scrape.
When metrics export is enabled, requestMetrics.snapshot() calls the Kiro projector. The projector calls getAccountSet("kiro"), which calls loadAuthStore() and can synchronously read the auth-store file. { hydrate: false } only disables quota-evidence hydration.
Pass an already-loaded roster to the projector or use a cache-only roster accessor.

Keep the Kiro note inside the transport table.
Lines 46–49 interrupt the Markdown table in structure/transports/inventory.md. The OAuth login callback row and every row after it will render outside the transport inventory table. Add the Kiro rules to the OAuth account failover cell, or move the paragraph below the complete table.
As per coding guidelines, structure/** inherits the repository-wide rules in AGENTS.md; the changed transport inventory must remain usable.

Summary
An operator running a Kiro pool had no way to see, outside the dashboard, how much of each account's allowance was left, and no way to tell from the account list why the pool was skipping an account: a suspended or exhausted account looked like any other row.
After this change:
opencodex_kiro_quota_percent, credits used, credit limit and seconds to reset — for up to 32 accounts under opaque labels (o+ 6 hex), from in-memory evidence only: no scrape-time upstream call and no disk read, rows dated in the future are dropped, and stale rows do not consume the 32-row budget. Credit balances now survive a restart.ocx account listreportautoSelectableand, when false, a closedskipReason(needs_reauth,suspended,cooldown,quota_exhausted); the CLI printsnot-auto-selected(<reason>). Eligibility itself calls the same function for Kiro, so what the list shows is what routing does.
