Colin McDonnell 5f3e46c42d fix: don't reuse disabled proxy key on workflow re-runs; non-fatal title-gen errors (#636)
* fix: don't reuse disabled proxy key on workflow re-runs; non-fatal title-gen errors

Three small surgical fixes addressing run https://github.com/pullfrog/app/actions/runs/25580969379:

1. **`/api/proxy-token` idempotency now checks `finalizedAt`.** GitHub re-runs
   share the same `run_id` (only `run_attempt` increments), so attempt N+1's
   action calls /api/proxy-token and inherits attempt N's `proxyKeyId`. The
   `workflow_run.completed` webhook between attempts retires that key on
   OpenRouter (`disableKey`), so attempt N+1 was getting back a disabled key
   and OpenRouter responded with `401 User not found` on every call. Falling
   through when finalized routes through the same billing gate
   (`handleRouterBilling` balance check), so no new attack surface.

2. **OpenCode title-gen / small-model errors no longer fatal.** OpenCode
   auto-spawns a small `agent=title small=true` background call at session
   start to name the thread, defaulting to `anthropic/claude-haiku-4.5`
   (anomalyco/opencode#1243). Pre-fix, the wrapper's `error` event handler
   treated any `type=error` as fatal, so a cosmetic title failure killed the
   run before primary inference even started. Now: stderr matching `small=true`
   sets a one-shot suppression flag for the next stdout `error` event, which
   is logged as a warning instead.

3. **Provider-error classifier puts auth patterns above rate-limit.** OpenRouter
   401 payloads bundle `x-ratelimit-*` response headers, and the loose
   `\brate[_ ]limit/i` pattern was winning. Added 401/403 status, `User not
   found`, `Invalid authentication`, `No auth credentials found` patterns
   ahead of rate-limit. Updated the existing 401-headers regression test to
   assert correct auth classification rather than `null`.

* opencode: correlate small-model error suppression by message, not by next-event

Pullfrog self-review on #636 flagged a real concurrency hole. OpenCode forks
the title-gen call (`session/prompt.ts:1452-1457` via `Effect.forkIn(scope)`)
so it races primary inference. The previous one-shot `suppressNextErrorEvent`
boolean had no per-call correlation: it was consumed by whichever stdout
`type=error` event landed next, regardless of which subagent produced it.
Under concurrent failures, a primary-agent error landing first could be
silently downgraded to a warning while the small-model error then propagated
fatally — the inverse of the bug the suppression was meant to prevent.

Replaced the boolean with a `Set<string>` of pending small-model error
messages. stderr extracts the inner `"message":"..."` from any classified
provider error tagged `small=true`; the stdout `error` handler suppresses
only when `event.error.data.message` matches a pending entry. Set is capped
at 32 entries so a long stream of small-model failures can't wedge memory.

Also corrected the comment that referenced "session summarizer" — verified
in opencode source that summarize() does NOT use `small: true`; only the
title generator does today (only `small: true` match in the codebase).

* revert: drop opencode title-gen suppression

We have no evidence — and can't construct a realistic scenario — where
title-gen fails on an otherwise-successful run. Title-gen and primary share
the same OPENROUTER_API_KEY and hit the same proxy/upstream; whatever breaks
one breaks the other. The original repro on run 25580969379 is fully
explained by the stale proxy key (fix #1) — title-gen happened to be the
first call that surfaced the auth error, but every subsequent primary call
would have died the same way.

Suppression code adds complexity (cross-stream correlation logic, message
matching, set capping) and a real failure mode of its own (a small-model
error with a unique message could mask an unrelated primary error landing
shortly after). Net negative. Removing.

Colin McDonnell ec43c0e0d1 router: fix bugs from PR #616 review (#625)
Three real defects flagged in the post-merge review of #616, plus one cheap
hardening:

1. OpenCode `limit.output` override was a silent no-op on opencode-ai@1.1.56.
   Top-level `limit.output` has no read site in OpenCode (verified against
   the v1.1.56 source: `OUTPUT_TOKEN_MAX = Flag.OPENCODE_EXPERIMENTAL_OUTPUT_TOKEN_MAX
   || 32_000` in session/llm.ts; per-model `model.limit.output` has its own
   scope). Plumbed via `OPENCODE_EXPERIMENTAL_OUTPUT_TOKEN_MAX=5000` env var
   on the OpenCode spawn instead. Drops dead `OpenCodeConfig.limit?` type
   field and the corresponding config write in `buildSecurityConfig`. This
   was the headline mechanism of #616 — without the env var, the upfront
   `max_tokens` reservation stayed at 32_000 and low-wallet runs continued
   failing the way #616 was supposed to prevent.

2. Phantom auto-reload buffer for detached-card accounts. DELETE
   /payment-method clears `stripeCustomerId` but leaves `autoReloadEnabled`
   intact, so an account with welcome-credit residue and a detached card
   could mint a key with `keyLimitCents = balance + autoReloadAmountCents`
   ($50 default, schema-cap $100K) of free spend headroom we have no way
   to bill. Conjunctive `account.autoReloadEnabled && hasCard` in the
   buffer selection closes this. Defense-in-depth follow-up worth doing:
   clear `autoReloadEnabled` in the card-detach handler.

3. The autoReloadEnabled 402 branch fired for phase-1 noop paths
   (`!stripeCustomerId`, `reloadAmountCents < 50`, `balance >= threshold`)
   where `result.failure == null`, returning `"insufficient balance"` with
   no actionable code. Gated on `result.status === "failed"` so non-charge
   paths fall through to the `hasCard` / no-card branches and emit
   `router_balance_exhausted` / `router_requires_card` instead.

4. (cheap) `ROUTER_KEYLIMIT_EXHAUSTED_PATTERN` now uses `/is` instead of
   `/i` so `.*?` crosses newlines. Defends the BillingError reclassification
   against any upstream layer that wraps the OpenRouter error onto multiple
   lines. Trivial.

Test plan: 488/488 unit tests pass (1 new test for newline regex behavior).

Colin McDonnell 4101df566b router: decouple per-run key budget from wallet, add overdraft buffer (#616)
Replaces today's `keyLimitUsd = min(walletBalance, $25)` with population-aware
buffers so users can use 100% of their credits before being paywalled, and
opaque mid-run "more credits" failures (e.g. https://github.com/pullfrog/app/actions/runs/25531633203)
get a clear PR comment instead of a generic stack-trace dump.

Policy matrix:
- Auto-reload accounts: `wallet + autoReloadAmountCents` (default $50, no cap)
- Card + no-autoreload: `wallet + $5` overdraft buffer
- No card: `wallet` (no buffer; existing zero-balance 402 stays)
- OSS: `$10` (unchanged)

Removes the $25 per-run cap entirely. Long Build runs at high-balance
accounts no longer silently cap at $25.

Other changes:
- Classify mid-run OpenRouter "requires more credits, or fewer max_tokens"
  errors as `router_keylimit_exhausted` BillingError so users get an
  actionable PR comment.
- Override OpenCode `max_tokens: 32000` default to `5000` via
  OpenCodeConfig.limit.output. Drops Opus per-call upfront budget reservation
  from ~$2.40 to ~$0.38 — what makes low-wallet runs viable at all.
- Switch `findInitialComment` and `findExistingPaywallComment` to GraphQL
  `issueOrPullRequest(number:) { comments(last: 100) }` (single round trip,
  actually returns newest-100; REST listComments doesn't support sort/direction).
  Also fixes a latent `comments.find()` returning the OLDEST match instead
  of the most recent — now selects max(databaseId).
- Wrap `syncAccountUsage` in `prisma.$transaction` with `SELECT ... FOR UPDATE`
  on the account row. Pre/post-balance reads inside the transaction enable
  deterministic low-balance edge detection (currently logs; will push the
  outreach.low_balance task once #592 lands).

Plan: .cursor/plans/router-low-balance-paywall.plan.md (in companion wiki-billing branch)

pullfrog[bot] 6f76a6a9da fix(action): tighten provider error detection and propagate agent error events (#580)
* fix(action): tighten provider error detection and propagate agent error events

Both bugs from #562:

1. detectProviderError used substring matches against "429", "rate limit",
   etc. — false-positives on commit SHAs containing 429 and on x-ratelimit-*
   response headers in dumped 401 error JSON. rewrote with anchored regexes:
   numeric status codes only match adjacent to a recognised status key, and
   `\brate[_ ]limit(?=[_ ]|\b)` rejects ratelimit-* headers (no separator).
   word-boundary anchors on INTERNAL / UNAVAILABLE / quota / limit:0 reject
   INTERNAL_SERVER_ERROR / time_limit:0 substrings. added 11-case regression
   test.

2. opencode 401s slipped through `eventCount === 0 && lastProviderError`
   because opencode's own type=error event increments eventCount before
   the guard runs. added an explicit `error:` handler that captures the
   event and propagates it to a non-success AgentResult. opencode emits
   the message under `error.data.message`, not the top level. mirror fix
   in claude.ts: error_max_turns / error_during_execution / any error*
   subtype on the result event now flips success: false.

* fix(action): match quota inside identifiers like insufficient_quota

\bquota\b missed insufficient_quota / quota_exceeded / quotaExceeded
because _ is a word character and camelCase has no boundary. quota is
specific enough to be matched as a plain substring.

* fix(action): match `rate limited` and `rate limits exceeded`

Drop the trailing `(?=[_ ]|\b)` lookahead from the rate-limit regex. The
lookahead failed when `limit` was followed by another word character
(`limited`, `limits`), so `rate limited` and `rate limits exceeded` were
slipping past detection. The leading `\b` plus `[_ ]` separator already
rejects `x-ratelimit-*` / `anthropic-ratelimit-*` headers without it.
