Review: scope durable onboarding admissions (#17546 → #17463)
Static review only. I inspected the exact head 09a7530eb1ca41b0a1d7bdb1121710e5d1830f79 from a trusted control checkout (gh pr view/diff/checks, git show against origin/develop). I did not check out the PR head, install dependencies, or execute any of its code, so no runtime verification of the claimed test results was performed. Every finding below is derived from reading the diff against origin/develop (332bdc638) and the surrounding trusted sources (packages/cloud/shared/src/lib/services/eliza-app/onboarding-chat.ts, packages/cloud/api/CLAUDE.md, the repo PR template).
The direction is right: replacing the single ledger value with session: / history:<n> / replay:<key> records genuinely fixes the unbounded-value and 64-entry-eviction defects from #17463, and the per-scope key derivation is a real improvement. Five correctness/robustness gaps and two evidence gaps block approval.
Blocking
1. src/onboarding-session-coordinator.ts:308-310 — an authenticated turn destroys the trusted-platform durable record.
if (sessionKey !== platformSessionKey) {
await this.state.storage.delete(platformSessionKey);
}This runs on every turn that carries authenticatedUser, not only on a successful migration. Note that runOnboardingChatWithStore (onboarding-chat.ts, "session bound to a different user; starting fresh session") replaces the loaded session with a brand-new random-id session when session.userId !== input.authenticatedUser.userId. In that path the platform session is not migrated anywhere — it is simply deleted.
Failure scenario: Discord user U chats over the gateway (platform:discord:U, several turns persisted under session:platform:...). Account B (a different cloud account that resolved to the same session id via a continuation token) sends one authenticated turn. The guard rejects adoption and mints a fresh UUID session for B; line 309 then deletes session:platform:discord%3AU. U's next gateway turn (trustedPlatformIdentity: true, no authenticatedUser) finds no durable record, no legacy ledger, and falls through to loadCachedOnboardingSession — the KV mirror that finding #2 makes unreliable. U's onboarding silently restarts.
Repair: only delete the platform record when the turn actually adopted it (storedSession came from platformScope) and result.session.id === request.sessionId; otherwise leave it. Add a test that runs a platform turn → an authenticated turn from a different account → a platform turn, and asserts the third turn still sees the first turn's history.
2. src/onboarding-session-coordinator.ts:228-242 (called at :268 and :312) — the mirror is fire-and-forget with no waitUntil.
mirrorSessionBestEffort returns void and leaves a floating promise. Two consequences:
- In workerd a promise not tied to the request lifetime (or
state.waitUntil) may be cancelled once the response is returned, so the mirror can simply never run. Given finding #1, the mirror is now load-bearing for platform-session recovery — this is not merely diagnostic state despite theerror-policy:J7comment. - Ordering is lost. Turns 1 and 2 arrive back to back; the serialized queue no longer covers the mirror, so mirror(1) can resolve after mirror(2) and write the older session over the newer one in
eliza-app:onboarding:<id>and the continuation key.
Repair (smallest coherent fix): keep the .catch(...) that logs and swallows, but await the resulting promise inside runTurn. That preserves the J7 non-fatal semantics and restores execution guarantee and ordering, since runTurn already runs inside serialize(). Then add the mirror-failure test (see #7).
3. src/onboarding-session-coordinator.ts:40, 264-273 — the "14 days with explicit expiry" retention contract is not actually enforced.
REPLAY_RETENTION_MS is only consulted when the same idempotencyKey is re-presented (:264), and the only delete is on that same key (:272). There is no alarm and no storage.list({ prefix: "replay:" }) sweep, so in steady state the DO accumulates one permanent replay: key per delivered message forever. The PR body and the issue both promise bounded durable records with an explicit expiry; the per-value size is now bounded, but the per-object key count is not.
Repair: schedule state.storage.setAlarm(...) and implement alarm() to list({ prefix: REPLAY_KEY_PREFIX }) and delete entries with expiresAt <= Date.now(), re-arming while entries remain. Verifiable by a test that stores N expired entries, invokes alarm(), and asserts list({ prefix }) is empty.
4. src/onboarding-session-coordinator.ts:86 — a missing history chunk is silently swallowed.
return { ...session, history: chunks.flatMap((chunk) => chunk ?? []) };If any index in 0..historyChunkCount-1 is absent (partial write, interrupted migration, an orphan-cleanup bug), the coordinator returns a transcript quietly missing 10 messages and reports success. That also breaks replayResult's historyEndMessageId lookup, which then silently falls back to the 2-message historyTail — a wrong-but-plausible replay body. Per the package/root failure-surfacing rules this should throw at the persistence boundary rather than degrade.
Repair: if (!chunk) throw new Error(...) inside the map, with a test that deletes history:<scope>:1 and asserts the turn fails loudly instead of returning a short history.
5. packages/cloud/api/scripts/onboarding-latency-report.ts:16-19 — not updated for the new storage API.
BenchmarkStorage still only implements put(key: string, value) and has no delete. The coordinator now calls this.state.storage.put(writes) with a single object argument, so the benchmark executes values.set(<object>, structuredClone(undefined)) — every subsequent get returns undefined. Every one of the script's 100 "unique" turns is a cold start, the 100 "cachedReplay" samples never hit the replay path at all, and the reported p50/p95 are for a different code path than the name claims. The test harness in __tests__ was updated for exactly this (object-form put, delete); the script was not.
Repair: mirror the TestStorage changes into BenchmarkStorage, and re-run the latency report if it is part of this change's evidence.
6. Evidence: the gate is red and the template is gone.
Develop PR Gate(run 30702978904) failed: at poll 80 all seven required checks —lint,typecheck,build,gitleaks,check-pr-evidence,check-pr-title,stale-base guard— reportedFAILED … no GitHub Actions check run. There is no exact-head CI for this head; the PR body'stypecheck/bun testclaims are self-reported only and were not reproduced here.- The PR body replaces
.github/pull_request_template.mdentirely with a free-form Summary/Evidence/Attribution block. None of the<!-- attribution-row:* -->markers, the Definition-of-Done checkboxes, the Risks section, or anevidence-headSHA marker are present — which is precisely whatcheck-pr-evidencegates. Restore the template, fill every row (N/A - <reason>where it truly does not apply), and runnode scripts/pr-evidence.mjs rows 17546 --row ...after the final push. - The head is 7 commits behind
origin/develop(merge-baseb5eb7e3d52920e08a73fc04a3396d95e27e8fe77), sostale-base guardcannot pass as-is. Rebase before re-capturing proof. packages/cloud/api/CLAUDE.mdrequires multi-tenant isolation proven including denied-access paths, plus request→response traces against the local cloud stack and the DB/durable state the change produced. No durable-state dump or trace is attached.
7. Test coverage: the required mirror-failure case is missing.
Issue #17463 enumerates the required tests as "cross-account collisions, duplicate deliveries, restart/replay, capacity pressure, expiry, and mirror failure." The added suite covers the first five; there is no test in which mirrorOnboardingSessionToCache rejects and the turn still returns 200 with the persisted result. Since that is the entire justification for the error-policy:J7 change at :229-231, it is the one behavior that most needs a test — and it would also have surfaced finding #2.
Non-blocking
- Orphaned chunks.
:309deletes onlysession:<platformScope>;history:<platformScope>:0..nare never removed. Same for stale high-index chunks when a session shrinks (storedSessionEntrieswriteshistoryChunkCountchunks but never deletes indices beyond it). Reads stay correct, but the DO leaks storage indefinitely — worth fixing given the issue is about bounded durable state. - Non-atomic migration.
:304,:306,:309are three separate awaited storage operations. Wrap them instate.storage.transaction(...)so a failure between them cannot leave the legacy ledger present alongside the new records. legacySessionFor:122.if (!authenticated) return session;hands an account-bound legacy session (withuserId/organizationId) to an unauthenticated trusted-platform caller, which makesrequiresLoginfalse and triggersensureElizaAppProvisioningfor that org from a gateway turn. This matchesdevelop's prior behavior so it is not a regression, but the migration window is the right moment to tighten it.- Isolation test strength (
__tests__/onboarding-session-coordinator.test.ts, "keeps identical delivery ids isolated by authenticated account"). The assertions (second.session.userId === "user-b", history excludes A's message) already hold ondevelopvia the "session bound to a different user; starting fresh session" guard inrunOnboardingChatWithStore— the test does not discriminate the new scoping from the old guard. Assert on the stored keys directly (e.g.session:account:org-a:user-astill present and intact after B's turn, andreplay:account:org-b:user-b:...distinct from A's) so it fails if the scoping is removed. - Provisioning mock.
mock.module("../../shared/.../provisioning")mocks a dependency rather than the system under test, which is acceptable, but it means the capacity test's 65 turns never exercise the provisioning branch. Worth a one-line comment stating why, given the package's "no larp" mandate.
Verdict
Requesting changes. Findings 1-5 are correctness/robustness defects introduced by this diff; 6-7 are evidence gaps against the linked issue's own acceptance list and the repository template. I did not execute the branch, so the PR's stated test results remain unverified from my side — please re-capture proof on a rebased head with a green Develop PR Gate and attach the durable-state artifacts the package guide requires.

I reviewed exact head 900789bdc9baf59dd2f5ab87b950ab66955f8f3d. The earlier correctness fixes are present, but this is not yet safe at production scale.
alarm() performs an unbounded storage.list({ prefix: "replay:" }), materializes the full replay namespace, then executes one awaited delete per expired key inside a single transaction. This namespace grows once per admitted delivery and retains 14 days of records. Cloudflare documents that an unbounded list() reads every matched value into object memory and can hit the memory limit; its batched key APIs are capped at 128 keys, and large storage operations can time out/reset an object. The current in-memory test with one replay cannot exercise any of those platform limits. See https://developers.cloudflare.com/durable-objects/api/sqlite-storage-api/ and https://developers.cloudflare.com/durable-objects/observability/troubleshooting/.
Please make cleanup bounded and resumable (for example, expiry-ordered/indexed records or a durable paged sweep cursor; deletion batches no larger than the platform limit; re-arm until the sweep completes), while preserving the next unexpired alarm across pages. Add a test with more than one batch that proves progress, resumption, and next-alarm selection.
The PR also still lacks the package-required real boundary proof: request-to-response traces against the local cloud stack, structured logs, and inspection of durable state for admitted and denied tenant paths. The body currently marks full verification and live runtime validation as unrun. Please provide that evidence and a current full bun run verify result before approval.

Added local cloud-e2e proof on exact head 46bbcf3ce7e3c9a4d055bc2166ea7cff25c2f509. Real local path exercised:
The test attaches the three raw request-response results as onboarding-tenant-isolation-trace to the Playwright test result. It passed locally in 1m 00s against the real Worker plus local PGlite, Hetzner mock, control-plane mock, and Durable Object: bun run --cwd packages/test/cloud-e2e test -- tests/onboarding-tenant-isolation.spec.ts Also passed: Biome on the new spec and git diff --check. The package-wide cloud-e2e typecheck remains blocked before this spec by existing unresolved workspace imports in other specs; I have not claimed it green. AI provider/model: OpenAI / gpt-5 |

Reviewed head 46bbcf3ce3aa601ab1309968e4c41cffff45e74d. The tenancy fix is sound and the parts that are easy to get wrong are right — I went looking for the usual failure in this shape and did not find it.
The adoption fence holds
legacySessionFor is the piece I expected to leak, and it does not:
if (!authenticated) {
return session.userId || session.organizationId ? undefined : session;
}
if (!session.userId && !session.organizationId) return session;
return session.userId === authenticated.userId &&
session.organizationId === authenticated.organizationId
? session : undefined;An anonymous caller cannot inherit a legacy ledger that already carries an owner, an authenticated caller can only adopt an unowned one or an exact match, and a mismatch falls through to undefined rather than to the unscoped record. That is the right shape for a migration path that has to keep working while old ledgers drain.
The platform-to-account promotion is likewise fenced on result.session.id === request.sessionId, so the platform record survives when adoption did not actually happen, and the whole put/delete set commits inside one storage.transaction. Reading platformHistoryKeys before opening the transaction rather than listing inside it is also the correct ordering.
Two other details worth naming because they are deliberate and a later reader might undo them: the fail-closed throw on a missing history chunk (a partial history silently rendered as a complete one is far worse than an error), and the error-policy:J7 mirror downgrade with the comment explaining that a cache outage must not report a persisted turn as a failed delivery.
The alarm's batch pagination with an explicit cursor, limit: REPLAY_CLEANUP_BATCH_SIZE, and setAlarm(now + 1) to continue in a fresh invocation is the right way to sweep an unbounded namespace inside a Durable Object, and seeding the nextExpiry reduce with cleanup?.nextExpiry correctly carries the minimum across batches.
Blocking: the evidence-head marker is stamped to a superseded commit
node scripts/pr-evidence.mjs verify 17546
[FAIL] evidence-head: does not match current PR head
… all seven rows [ok] …
Evidence gate FAILS.
The body carries <!-- evidence-head:900789bdc9baf59dd2f5ab87b950ab66955f8f3d --> while the head is 46bbcf3ce. Every row is otherwise satisfied and the N/A reasons are specific and correct for a Durable Object change, so this is purely the re-stamp after the last push:
node scripts/pr-evidence.mjs rows 17546 --row ...Worth re-running after any further push — proof captured against an older head does not qualify, and this is the failure mode that makes an otherwise-complete evidence matrix read as incomplete.
Blocking: base is 203 behind and verify was not run
compare/develop...46bbcf3ce → diverged, ahead 4, behind 203
The body is straightforward that full bun run verify did not run, and records the targeted coordinator tests and Cloud API typecheck instead. That is the honest way to report it, but with 203 commits of drift in packages/cloud I would want the rebase and a completed verify before merge rather than after — the sibling PR #17545 is in the same position, and both touch cloud storage paths that other in-flight work also writes.
Non-blocking: a replay written mid-sweep can outlive its own alarm
The cleanup paginates with startAfter, so a replay created by a concurrent turn whose key sorts before the cursor is not visible to the remainder of that sweep. If the sweep then finishes with no unexpired entries scanned, it takes the deleteAlarm() branch, and the skipped replay has no alarm scheduled for it.
It is genuinely narrow, and it self-heals: the next runTurn that writes a replay sees currentAlarm === null and schedules one. So the entry only lingers if that Durable Object never takes another turn with an idempotency key — a dormant object holding one stale record for longer than REPLAY_RETENTION_MS. Not worth restructuring the sweep for; worth a line in the alarm comment so the next person reading deleteAlarm() knows the namespace is not provably empty at that point, only that the scanned range was.
Non-blocking: chunk writes never delete a shrinking tail
storedSessionEntries writes chunks 0..ceil(len / HISTORY_CHUNK_SIZE) - 1 and updates historyChunkCount. If a session's history ever gets shorter, the surplus history:<scope>:<n> keys stay behind. Reads are correct regardless, since loadStoredSession iterates by historyChunkCount and never sees them, so this is storage residue rather than a correctness bug — and on the normal append-only path it cannot arise at all.
I raise it only because the 65-message capacity case in the test suite implies history is bounded somewhere. If that bound trims from the front and keeps the length constant, nothing shrinks and there is no issue; if it can ever reduce the message count, the orphans accumulate silently. historyStorageKeys already exists and would make the cleanup a two-line addition inside the same transaction.
Smaller notes
historyStorageKeys calls storage.list({ prefix }) with no limit, in a file that elsewhere documents the 128-key batch cap and paginates carefully around it. At HISTORY_CHUNK_SIZE = 10 a session would need over a thousand messages to approach it, so this is fine today — but the asymmetry with the alarm's careful pagination is the kind of thing that reads as an oversight later. A limit with an explicit comment saying why it cannot be reached would settle it.
scopeFor runs encodeURIComponent on the identity components, which stops a : in an id from forging a different scope. That is load-bearing for the fence above and currently unstated — worth a comment, since a future refactor to template literals without the encoding would silently reopen the tenancy hole this PR closes.
Caveat: static review plus reads of your head through the GitHub API — the coordinator in full alongside the diff. The repository contract requires an isolated disposable sandbox to execute an untrusted head, which I do not have, so I ran neither the coordinator harness nor the new onboarding-tenant-isolation e2e spec; the reasoning above is from source. The mid-sweep window in particular is derived from the startAfter/deleteAlarm interaction rather than observed, and I would not hold the PR for it.

Thank you for the careful review. I agree the branch must be rebased before merge, and the evidence-head plus any full verification must then be recaptured on that final head. I am holding that one rebase until these fork workflow runs can actually execute. At present every pull_request workflow on this fork remains action_required, so rebasing now would invalidate the exact-head E2E evidence and local verification while producing the same no-run aggregate-gate outcome. The underlying held-run diagnosis is tracked in #17551, with #17577 proposing the fail-fast reporting improvement. Once a maintainer approves the fork runs or the workflow path is otherwise usable, I will rebase once, reinstall as needed, run the requested verification to completion, re-confirm the migration/evidence state, and publish a new exact-head marker. I will not represent the full verify as complete before then. AI provider/model: OpenAI / gpt-5 |

| 6 | evidence: template, gate, stale base | partly — see below |
| 7 | mirror-failure test missing | fixed |
1. The unconditional delete(platformSessionKey) is now gated on platformSession && result.session.id === request.sessionId — the record is removed only when the turn actually adopted it, which is exactly the discriminator that was missing. platformSession is itself only loaded when !scopedSession && scope !== platformScope, so the rejected-adoption path can no longer reach the delete at all. Covered by "keeps a trusted platform session after a rejected account adoption".
2. mirrorSessionBestEffort is now awaited at both call sites while keeping the internal try/catch that logs and swallows. That preserves the error-policy:J7 non-fatal semantics and restores both the execution guarantee and ordering, since runTurn runs inside serialize(). This is the minimal correct fix.
3. This is the one I'd call out as better than the repair I proposed. Rather than a single list({ prefix }) sweep, alarm() pages through REPLAY_CLEANUP_BATCH_SIZE = 128 with a persisted { startAfter, nextExpiry } cursor and re-arms at now + 1 while entries remain, so the full replay namespace is never materialized in one invocation — the DO batch cap is respected rather than discovered in production. Three details I checked specifically:
nextExpiryseeds its reduce fromcleanup?.nextExpiry, so the minimum carries correctly across batches rather than resetting per page.REPLAY_CLEANUP_STATE_KEYis"replay-cleanup-state", and"replay-"does not match the"replay:"prefix (-is0x2D,:is0x3A), so the cursor cannot list or delete itself.alarm()andfetch()both run insideserialize(), so a concurrent turn cannot land a new replay between the sweep's read and itsdeleteAlarm(). Worth stating out loud, because that mutual exclusion is what makes the finaldeleteAlarm()safe, and it isn't obvious from either method alone.
The setAlarm guard in runTurn (currentAlarm === null || replay.expiresAt < currentAlarm) also correctly declines to overwrite a mid-sweep now + 1 continuation alarm with a 14-day expiry, since the continuation is always the earlier timestamp. If a multi-batch sweep runs long enough that a previously-unexpired entry expires, nextExpiry lands in the past and the alarm re-fires immediately — self-correcting, which is the right failure direction.
4. The flatMap(chunk => chunk ?? []) is now an explicit loop that throws onboarding session history is incomplete for ${scope}. Covered by "fails instead of silently dropping a missing history chunk".
5. BenchmarkStorage now implements object-form put, delete(string | string[]), list({ prefix }), the alarm trio and transaction, so the script exercises the same storage surface as the coordinator instead of silently keying a Map on an object.
7. "returns the persisted result when cache mirroring fails" is present — the case issue #17463 enumerated and the one that justifies the J7 classification.
Three of the four non-blocking notes are also addressed: the migration is now wrapped in state.storage.transaction(...), orphaned history: chunks are deleted alongside the platform session via platformHistoryKeys, and legacySessionFor no longer hands an account-bound legacy session to an unauthenticated caller. The isolation test now asserts on the stored keys directly (session:account:org-a:user-a, both distinct replay: keys) plus a replay-equality check, so it discriminates the new scoping from the pre-existing runOnboardingChatWithStore guard, which was the point.
What is left — finding 6 only, and none of it is code
I am not re-requesting changes; the code is done as far as I can verify by reading. One mechanical item stands between this and merge:
The evidence-head marker is two commits stale, and one of them is production code. The body records <!-- evidence-head:900789bdc9baf59dd2f5ab87b950ab66955f8f3d -->, but d9aad0da7 landed after it with +35/-7 in src/onboarding-session-coordinator.ts — that commit is precisely the bounded-batch alarm() rewrite above. So the recorded evidence covers a version of the sweep that no longer exists, and the strongest new logic in the PR is the part it does not cover. (46bbcf3ce then added the e2e spec.) A test log is evidence for the commit it ran at and for no other; please re-run and re-stamp.
The branch is 415 commits behind develop (merge-base abb37c1d2), so stale-base guard cannot pass and the Definition-of-Done line claiming a rebase onto abb37c1d2 is no longer current. Since the rebase is mandatory anyway, the cheapest ordering is: rebase → re-run the targeted suite and the Cloud API typecheck → re-stamp evidence-head at the new head in one pass.
The red Develop PR Gate is not evidence against this change and is not yours to fix. I read run 30889135168: at poll 80 all seven required checks report FAILED … no GitHub Actions check run after forty minutes of waiting — the workflows never dispatched. That is the fork approval-hold pattern, not a code failure. It needs a maintainer to approve workflow runs on this PR; no push will clear it.
Two residual non-blocking notes, neither worth a round trip on its own:
storedSessionEntrieswriteshistoryChunkCountchunks but never deletes indices beyond it, so a session whose history shrinks leaks stale high-index chunks. Reads stay correct (they are bounded byhistoryChunkCount) and a regrowth overwrites them, so this is storage leakage only — but it is the same class of unbounded durable state the issue is about.BenchmarkStorage.listignoresstartAfterandlimit. Harmless today because the benchmark never invokesalarm(), but it means the harness would silently misreport the batching path if anyone ever pointed it there.
Re-stamp the evidence on a rebased head and I will approve.

Re-review at 46bbcf3ce3aa601ab1309968e4c41cffff45e74d
Static review only. I inspected this head read-only from a trusted control checkout (gh pr view/diff/checks, gh api contents/compare against develop). I did not check out the branch, install dependencies, or execute any of its code, so the PR's stated bun test and typecheck results and the new e2e spec are unverified from my side — findings 2-4 are traced from the source, not observed.
Correction to my comment of 2026-08-06
That comment concluded "the code is done as far as I can verify by reading" and "re-stamp the evidence on a rebased head and I will approve." I am retracting that conclusion. It was the answer to the wrong question: I checked whether my seven earlier findings were fixed — they are, and several more carefully than I asked — and did not ask what the fixes themselves introduced. Three of the four blocking findings below live in the platform→account adoption path, which is code that did not exist when I filed the original review. Reviewing only my own list is how a fix-induced defect merges.
I am also correcting a factual error in that comment: it names the head 46bbcf3ce8, which resolves to no commit. See finding 5.
Blocking
1. packages/test/cloud-e2e/tests/onboarding-tenant-isolation.spec.ts is added to a directory that no longer exists on develop.
The e2e harness moved: packages/test/cloud-e2e/ → packages/cloud/e2e/.
gh api contents/packages/test/cloud-e2e?ref=develop → 404
gh api contents/packages/cloud/e2e/src/helpers?ref=develop → …, test-fixtures.ts, …
The spec resolves only because the branch is pinned to a base 456 commits old. After the mandatory rebase, ../src/fixtures/seed and ../src/helpers/test-fixtures resolve to nothing and the spec cannot compile, let alone run. So the one artifact that would satisfy packages/cloud/api/CLAUDE.md's real-boundary requirement is currently unrunnable.
Repair: rebase, move it to packages/cloud/e2e/tests/onboarding-tenant-isolation.spec.ts (the relative import depth is unchanged), run it, attach the trace. The spec's content is good — routing both accounts at the same sessionId through the same DO and asserting the owner's third turn still sees turn one is a test that genuinely fails on develop. It is worth the rescue.
2. src/onboarding-session-coordinator.ts:346-349 — the adoption transaction orphans platform-scope replay records, and the orphan turns an at-least-once retry into a duplicate execution.
if (platformSession && result.session.id === request.sessionId) {
await transaction.delete(platformSessionKey);
for (const key of platformHistoryKeys) await transaction.delete(key);
}replay:<platformScope>:* is not in that set. Now follow a retried delivery at :291-303:
if (replay) {
if (replay.expiresAt > Date.now()) {
const session = await loadStoredSession(this.state.storage, scope);
if (session) { … return replayResult(replay, session); }
}
await this.state.storage.delete(replayKey); // :302
}Failure scenario: Discord delivery K arrives (unauthenticated, trusted platform) → writes session:platform:P, its history chunks, and replay:platform:P:K. The user then logs in on the web; the authenticated turn adopts the platform session (result.session.id === request.sessionId holds) and :346-349 deletes session:platform:P. The gateway — at-least-once, which is the entire reason idempotencyKey exists — redelivers K. Scope is platform:P; the replay entry is present and unexpired, but loadStoredSession(platform:P) now returns undefined, so control falls through to :302, deletes a valid replay record, and re-executes the turn. The user's message is appended a second time and a second assistant reply is generated.
That is a duplicate admission — the defect class in the PR title — and the migration guarantees its precondition rather than making it rare.
Repair: list replay:${platformScope}: before the transaction and delete or re-key it inside the same transaction, and on a replay hit with no scoped session fall back to the platform scope before discarding the entry. Test: platform turn K → authenticated adoption → repeat platform turn K, asserting the message appears exactly once and the third response is a replay.
3. :346-349 with :319 — after adoption, trusted-platform continuity rests entirely on a write whose failure this PR made silent.
Once the platform record is deleted, a later unauthenticated gateway turn on the same session id resolves scope === platformScope, so scopedSession is undefined, platformSession is skipped by the scope !== platformScope guard at :311, and the legacy ledger is gone. The only remaining source is loadCachedOnboardingSession(request.sessionId) at :319 — the KV mirror written by mirrorSessionBestEffort, which this PR deliberately changed to catch-and-log under error-policy:J7.
So a cache outage on the adoption turn permanently severs that user's transcript even though the Durable Object still holds it under account:<org>:<user>; SESSION_TTL_SECONDS is 14 days, so the same loss occurs for any gateway user returning after a two-week gap, mirror healthy or not. The J7 downgrade is correct in isolation — it is unsafe only because this diff simultaneously made that mirror the primary recovery path for the platform side. The new test "returns the persisted result when cache mirroring fails" asserts a 200 and a replay; it does not exercise migrate-then-platform-turn with a failing mirror, which is where the loss lives.
Repair: write a durable alias:<platformScope> → scope pointer inside the adoption transaction and resolve it before the KV fallback (or retain the platform session: record as a pointer stub), then add that test.
4. :319 — the ownership fence this PR adds is applied to one fallback and not the other.
legacySessionFor (:148-149) is explicit and correct:
if (!authenticated) {
return session.userId || session.organizationId ? undefined : session;
}loadCachedOnboardingSession(request.sessionId) at :319 has no equivalent check, so an unauthenticated turn reaching it gets a session carrying userId/organizationId — requiresLogin is false and ensureElizaAppProvisioning runs for that organization from a gateway turn. Reach is limited (sanitizeSessionId rejects platform: ids from untrusted callers, and the behaviour matches develop), so this would be a nit on its own. I am calling it blocking because tenancy scoping is the stated purpose of this diff, the fence is written and tested for one of the two fallbacks, and finding 3's repair has to touch this line anyway.

Verdict
Requesting changes. Findings 2-4 are correctness/durability defects at this head, and all three live in the platform→account adoption path — the part of this change with no end-to-end coverage. Finding 1 is why: the test that would have exercised it is stranded at a path the repository abandoned 456 commits ago. Rebase first — it turns the evidence problem and the coverage problem into the same fix.
To be explicit about the reversal: the direction of this PR is right and the work since 900789bdc is real. My earlier "I will approve" was premature, and withdrawing it is on me, not on you.

There was a problem hiding this comment.
The problem is real and unfixed — packages/cloud/api/src/onboarding-session-coordinator.ts on develop still has the single LEDGER_KEY and MAX_REPLAY_RESULTS = 64 ledger at :33/:35, so the cross-tenant durable record is live. But the branch is 476 commits behind, and the adoption path this PR introduces has three gaps of its own.
Blocking: the e2e spec cannot compile after rebase
packages/test/cloud-e2e/tests/onboarding-tenant-isolation.spec.ts — that harness moved to packages/cloud/e2e/ on develop (git ls-tree origin/develop packages/test/ has no cloud-e2e), and git merge-tree reports CONFLICT (file location) … suggesting it should perhaps be moved to packages/cloud/e2e/tests/. After the rebase ../src/fixtures/seed and ../src/helpers/test-fixtures resolve to nothing. That spec is the one artifact that would satisfy this package's real-boundary evidence requirement, so it needs to move (relative import depth is unchanged, so it is a straight move).
Blocking: adoption leaves replay keys behind → duplicate execution
The adoption transaction deletes platformSessionKey and every history:<platformScope>:* key, but leaves replay:<platformScope>:*. A retried at-least-once delivery then finds a live replay entry, calls loadStoredSession(storage, platformScope), gets undefined because the session was just deleted, falls through to storage.delete(replayKey) — and executes the turn a second time. That is exactly the duplicate execution the replay ledger exists to prevent. List and delete replay:<platformScope>:* alongside the session and history keys.
Blocking: nothing maps the old platform scope to the new account scope
After adoption, no durable pointer maps platform:<sessionId> to the account scope. The next unauthenticated gateway turn (trustedPlatformIdentity: true) finds no session, no legacy ledger, and falls through to loadCachedOnboardingSession — the KV mirror this same PR downgrades to best-effort with a J7 catch. The trusted-platform transcript silently restarts. Write an alias:<platformScope> → scope pointer and resolve it before the cache fallback.
The ownership fence is applied to one of two fallbacks
nextSession = storedSession ?? legacySession ?? (await loadCachedOnboardingSession(request.sessionId)). The fence written and tested in legacySessionFor — an anonymous caller cannot inherit an owned record — has no counterpart on the cache fallback. So an unauthenticated turn can still receive a session carrying userId/organizationId and trigger ensureElizaAppProvisioning for that org. Tenancy scoping is this PR's stated purpose, so this one matters most. Apply the same predicate to the loadCachedOnboardingSession result.
The test double cannot fail the assertions it guards
packages/cloud/api/__tests__/onboarding-session-coordinator.test.ts — TestStorage.transaction is operation(this): no buffering, no rollback. Both atomicity claims this PR makes (the adoption migration and the alarm sweep) are asserted against a double structurally incapable of violating them. Also delete(string[]) returns boolean where the real DO API returns number. Make it buffer writes and discard on throw, and add a test that a mid-transaction failure leaves the pre-state intact.

Definition of Done:
Contribution provenance
Sync with develop
Risks
Medium: durable onboarding persistence and replay cleanup. The change fails closed on incomplete history chunks, preserves platform state after rejected account adoption, and keeps cache failure non-fatal.
Background
What does this PR do?
Scopes session and replay records by account or trusted platform identity; stores session history in bounded chunks; expires replay records through a Durable Object alarm; and preserves ordering while treating the KV compatibility mirror as best-effort.
What kind of change is this?
Bug fix (non-breaking).
Documentation changes needed?
No project documentation change is required.
Testing
Where should a reviewer start?
packages/cloud/api/tests/onboarding-session-coordinator.test.ts
Detailed testing steps
Run bun test packages/cloud/api/tests/onboarding-session-coordinator.test.ts. The nine cases cover platform/account collision, 65-message capacity, restart replay, explicit expiry/alarm cleanup, missing chunk failure, mirror failure, tenant-scoped replay keys, and concurrent ordering.
Run bun run --cwd packages/cloud/api typecheck for TypeScript and Worker dry-run validation.

Exact-head CI has since executed at 46bbcf3: quality, security, lint, typecheck, unit/integration/e2e lanes are green; the only prior failure was the stale evidence-head marker, refreshed above. The submitted evidence is the in-process Durable Object harness plus Cloud API typecheck, re-run at head in a clean worktree.
Review follow-up addressed in 900789b: preserve the platform record on rejected account adoption; await-and-swallow ordered cache mirroring; alarm-based replay cleanup; fail closed on missing history chunks; benchmark storage API parity; and adversarial tests for each path.
