localOnlyFetch previously validated url.hostname after the WHATWG URL parser canonicalises it, so non-standard IPv4 spellings (0x7f.0.0.1, 2130706433, 010.0.0.1) silently slipped past the strict-literal loopback grammar in isLoopbackHostname. Switch both gates - the initial URL and every redirect hop - to validate the literal host extracted via extractRawHost, taken from the raw URL string BEFORE canonicalisation. The fallback to url.hostname is kept as defence in depth. Adds 7 unit tests covering hex/decimal/octal IPv4 spellings, bracketed IPv6 literal [::1], IPv6 zone identifier rejection, and the redirect canonicalisation pin-down behaviour (a Location: http://0x7f.0.0.1/ sent from a loopback origin is followed because next.href resolves to 127.0.0.1, which IS loopback). Supersedes #542. https://claude.ai/code/session_01Wws8oZpB5imjKL2e7DRXtc
…es, orphan reasons)
Three classes of issue addressed:
1. Key-injection scope escape.
userId, projectId, and every credential key are now matched against a
strict SAFE_SEGMENT grammar (^[A-Za-z0-9_-]{1,128}$). Without this, a key
like "../../other-user/other-project/leaked" could be smuggled through
vaultId() and collide with another scope's vault id. Failures are surfaced
as TypeError without echoing the invalid value back.
2. Delete races and orphan-overwrite.
- delete() is refactored onto an internal deleteById() helper that
deletes metadata FIRST, then vault. A throw on metadata.delete leaves
the entry fully intact and readable; a throw on vault.deleteSecret
reinstates a pending orphan marker (with orphanReason
"vault-delete-failed") so readers see absence and operators can
reconcile, AND surfaces a wrapped error whose message distinguishes
"orphan marker persisted" from "orphan marker also failed to persist".
- deleteById skips rows whose metadata is pending: true. This closes
both the orphan-overwrite path (delete on an existing orphan marker
used to nuke the vault entry it was tracking) and the concurrent
put(new)+delete race (delete during the pending window of a new-entry
put would wipe the vault entry mid-write).
- get()/has() wrap expiry self-eviction in try/catch so a transient
KV/vault failure during eviction does not surface as a thrown read.
- deleteAll() collects per-row failures and throws AggregateError so a
single bad row no longer silently masks deletion of the rest.
3. Orphan reason discriminator.
CredentialMetadataRow gains an optional orphanReason field
("vault-write-failed" | "metadata-commit-failed" | "vault-delete-failed")
and a corresponding exported OrphanReason type. Both put() orphan
paths and the new delete() orphan path stamp the reason so operator
tooling can pick a remediation strategy without re-running the original
write. Legacy rows without the discriminator stay invisible to readers
(covered by an explicit test).
14 new tests added; existing delete-removes-both test upgraded to assert
metadata-first ordering via spy call-order; existing put orphan tests
upgraded to assert orphanReason.
Supersedes #541.

…ore (sec) Follow-up to #543. Two contract regressions discovered in code review: H1: deleteAll() silently skipped pending/orphan rows because it now delegates to deleteById (added in #543) which short-circuits when pending=true. Result: no public API cleared orphan markers; a "wipe scope" call silently leaked the very rows operators need to clean up. Adds forceDeleteById that bypasses the pending-skip; deleteAll uses it. deleteById (single-key) unchanged. H2: get/has/delete now threw TypeError for invalid keys because they all routed through vaultId(). ICredentialStore documents these as returning undefined/false on missing keys; throwing breaks substitutability with InMemoryCredentialStore / EncryptedKvCredentialStore. Adds isSafeKey() predicate; readers short-circuit; put() still throws via vaultId (only path that persists a colliding id). M1: SAFE_SEGMENT widened from [A-Za-z0-9_-] to [A-Za-z0-9._:-] so natural credential names like "openai.prod" and "scope:billing" are accepted. Still rejects path separators and whitespace. 5 new tests + 1 rewritten test. Existing tests pass.

Still rejects path separators and whitespace. 5 new tests + 1 rewritten test. Existing tests pass. * docs(storage): clarify deleteById JSDoc + fix deleteByid typo (review) Copilot review feedback on #544: - deleteById's JSDoc claimed both delete() and deleteAll() share its code path, but deleteAll() deliberately routes through forceDeleteById() to bypass the pending-row short-circuit and reach sticky orphan markers. Updated to call out the asymmetry with a forward reference to forceDeleteById. - Typo: 'deleteByid' -> 'deleteById' so the @link symbol resolves. * refactor(storage): extract commitDelete to dedupe ServerCredentialStore delete paths `deleteById` and `forceDeleteById` had nearly-identical bodies after the pending-row check — the metadata-first ordering, orphan-marker rewrite, and wrapped-error throw were duplicated, so a fix in one could silently drift from the other. Lift the shared tail into `commitDelete(id, key, existing, op)` so both callers route through one source of truth and the only meaningful divergence (pending-row policy) stays at the call site. Also corrects the stale `vaultId` JSDoc that still listed the reader methods as callers — they were moved to `isSafeKey` in the same PR for the ICredentialStore-contract substitutability fix. https://claude.ai/code/session_011KMd9sERp2rguyekAi8a3u --------- Co-authored-by: Claude <noreply@anthropic.com>
…w IPv6/redirect tests PR #542 (Plan A initial-URL hardening) and PR #544 (Plan B ServerCredentialStore hardening) landed on main and superseded both commits in this branch. Reset the three production files to main's versions and keep only the 4 IPv6 / redirect-canonicalisation tests that main does not yet have. Files reset to match main: - packages/ai/src/provider-utils/localOnlyFetch.ts (#542) - packages/storage/src/credentials/ServerCredentialStore.ts (#544) - packages/storage/src/credentials/ServerCredentialStore.test.ts (#544) File retaining net additions (4 new tests): - packages/test/src/test/ai-provider-api/localOnlyFetch.test.ts - accepts bracketed IPv6 loopback [::1] (positive) - rejects IPv6 zone identifier [::1%25eth0] - pins redirect behaviour: Location: http://0x7f.0.0.1/ from a loopback origin is followed because WHATWG canonicalises the target to 127.0.0.1 - accepts bracketed IPv6 in a redirect Location Verified locally on the rebased branch with `vitest run` against both test files: 19/19 localOnlyFetch + 31/31 ServerCredentialStore pass.
…tch tests Continuation of the previous rebase commit. Resets the two ServerCredentialStore files to main's versions (PR #544 hardening landed there) and updates the localOnlyFetch test file to main's content plus the 4 new IPv6 / redirect-canonicalisation tests. After this commit the PR diff against main is exactly: - +4 tests in packages/test/src/test/ai-provider-api/localOnlyFetch.test.ts

Status after rebase onto current main
Both original commits of this PR were superseded by changes that landed on main:
localOnlyFetchSSRF hardening is fully on main via fix(ai): close WHATWG canonicalisation bypass in localOnlyFetch (sec) #542 (fix(ai): close WHATWG canonicalisation bypass in localOnlyFetch initial-URL check). The initial-URL gate already validatesextractRawHost(input)against the strict-literal grammar; the redirect path correctly relies onurl.hostname(which equals the WHATWG-canonical serialisation ofnext.href— pinned by the new redirect test below).ServerCredentialStorehardening is fully on main via fix(storage): restore ICredentialStore contract on ServerCredentialStore (sec) #544 (fix(storage): restore ICredentialStore contract on ServerCredentialStore). All sub-fixes are present:SAFE_SEGMENTkey/scope grammar (widened to[A-Za-z0-9._:-]so legitimate keys likeopenai.prodandscope:billinground-trip),orphanReasondiscriminator, metadata-first delete ordering,isPendingguard indelete, triple-failure error message correctness,AggregateErrorindeleteAll, and self-evictiontry/catchinget/has.What remains in this PR after rebase: 4 additional regression tests in
packages/test/src/test/ai-provider-api/localOnlyFetch.test.tsthat main does not yet have:accepts an initial IPv6 loopback literal in brackets (positive case)—[::1]rejects an initial IPv6 with a zone identifier—[::1%25eth0]follows a redirect whose Location uses a hex IPv4 spelling — the canonical form is loopback— pins the documented behaviour that aLocation: http://0x7f.0.0.1/is followed because WHATWG canonicalisesnext.hrefto127.0.0.1, which IS loopbackfollows a redirect to a bracketed IPv6 loopback (positive case)A note on the visible diff
Because the rebased history could not be force-pushed in this environment, the displayed PR diff (vs the stale
base.sha) still shows the original Plan A and Plan B work. The actual file contents on the PR head, however, match main exactly for the three production files (localOnlyFetch.ts,ServerCredentialStore.ts,ServerCredentialStore.test.ts); the only net-new lines vs current main are the four IPv6 / redirect-canonicalisation tests above. Merging this PR will therefore add only those four tests to main.A maintainer with push rights may want to force-push a rebased branch to clean up the diff view before merging.
