The decorator that dual-writes snapshots to Redis has to own the snapshot id, or the same snapshot carries a different id in each store and the comparator chases a difference that is not real. Four of the six snapshot input types had no id field, so four write sites could not carry one. Add it to CompletionSnapshotInput, ExpireSnapshotInput, RescheduleSnapshotInput and CreateExecutionSnapshotInput, and thread it through every nested create. createCancelledRun built its create inline and dropped the id its input already carried; it now passes it too. The field is optional everywhere, so an absent id still falls through to Prisma's @default(cuid()) and no existing caller changes.
…ators RunStore has 71 members. A decorator that intercepts a dozen of them should not restate the other 59 forwarders alongside its real logic, and hand-writing them invites a typo no test would catch. Generate the base from the interface instead. The generator also emits the member-name lists, so the suite can assert that the class and the interface hold exactly the same members: a method added to RunStore and not to the base fails a test rather than becoming a silent hole in the decorator. The one data property on the interface becomes a getter over the delegate, read live rather than captured, so a delegate whose client changes is not cached.
…parity tests No nested write site returns the snapshot it created: createRun returns the run, expireParkedRun returns a count, and the rest return a selected TaskRun. So the Redis entry is built from each site's own input plus the caller-minted id. That means every value Postgres derives rather than receives has to be reproduced: the DEQUEUED-to-PENDING rewrite, the four values lockRunToWorker hard-codes, the three rescheduleRun defaults, and the engine column default a completion leaves unset. The parity suite covers all ten physical write sites, comparing the built entry against the row Postgres actually wrote. It caught the dropped id in createCancelledRun.
…write The last dial position makes the Redis store the sole snapshot writer, so Postgres has to stop writing snapshot rows without changing anything else it does. One constructor flag does that across all ten write sites. With it off, the nine nested creates are omitted and the run mutation still lands; createExecutionSnapshot echoes its input in the shape callers expect rather than inserting; and the completed-waitpoint join inserts are skipped, since they would otherwise link to a row that no longer exists. Defaults to true, so every existing caller and test is unaffected.
A decorator over any RunStore that also writes execution snapshots to Redis. It overrides only the methods that touch a snapshot and inherits the rest. Write order is the correctness property, and the two orders differ on purpose. A transition writes Postgres first: a crash in the gap leaves a stale latest snapshot, which the heartbeat stall watchdog already heals. A birth writes Redis first: a crash there leaves an unreachable key for a run that does not exist, where Postgres-first would leave a run with no snapshot at all and no way to read one. Each order is chosen so the crash state is the harmless one. A failed transition append retries three times, then hands the run to the repair job. It never rethrows, because Postgres has already committed and a throw would turn a healable gap into a caller-visible error. A failed birth append is survivable before redis-only, where Postgres still holds the snapshot, and refuses at redis-only, where it would otherwise create a run with no snapshot anywhere; refusing works only because the birth append comes first. None of the four non-failure append outcomes enqueues a repair: an absent keyspace is every pre-cutover run's transitions, a fork means another writer advanced the head, a duplicate is a retry that landed, and a cycle mismatch is the store refusing an untrustworthy pointer on purpose. At mode off the decorator makes no Redis call and builds no entry.
…ore handles Proves the deferral from inside the transaction callback rather than assuming it: a staged append is absent from Redis while the transaction is open and present once it commits, and a rollback leaves both stores agreeing the transition never happened.
The engine resolves its since-cursor to a createdAt before it asks for the window, so the snapshot id is gone by then and the id-addressed read cannot serve it. Adding a cursor-addressed read is the alternative to changing the engine's read path, which stays untouched. The cursor is exclusive and keeps the same-millisecond blind spot the Postgres read has. Matching it is the requirement, not an oversight: a Redis read that is more correct than the Postgres read shows up as divergence during compare mode, which exists to surface real defects. Closing the blind spot needs seq ordering on both sides and belongs after the cutover. The walk goes newest-first and stops at the first entry at or before the cursor, so its length is the length of the answer rather than the run's history. This adds a read operation. It does not touch the append script, the keyspace, or the write-ordering protocol.
…back Two of the five snapshot reads take arbitrary Prisma arguments, and a key-value store cannot answer an arbitrary query. Only three production call sites exist, all in the engine's executionSnapshotSystem, and both generic ones send a single fixed shape, so the decorator recognises exactly those shapes and delegates everything else. Each matcher rejects an argument object carrying a key it does not know, because a query that has drifted must be answered correctly by Postgres rather than approximately from Redis. A miss is the coexistence path, not an error: a pre-cutover run or expired history falls back to Postgres. The entry supplies every scalar column, and the checkpoint and waitpoint rows are read back through the delegate only when the entry says they exist, so the common read of a running run makes no Postgres call at all. Which runs read from Redis is a hash of the run id, so a run does not change store between two reads of one poll, two instances of the same dial agree, and raising the dial only ever adds runs to the cohort.
Two rules, because neither can see what the other leaves behind. A terminal run whose keyspace never received the completion expiry gets one applied, so it reaps on the schedule a healthy terminal append would have set. A keyspace with no run row at all, past an age threshold, is deleted outright — that is a crashed birth, which is non-terminal so it carries no expiry and has no run row, so the first rule can never match it. It never reaps on an unknown answer: a live run is left alone however old its keyspace, a young orphan is left for the birth that may still be in flight, and a batch whose run lookup failed is skipped rather than treated as absent. Run rows are resolved through the run store rather than a raw client, because under the run-ops split a run can live on either database and a raw lookup would report a live run as an orphan. Nothing schedules this. The engine's worker has to run it, and run-store cannot reach the engine. Also moves the decorator suites onto the worker-scoped container fixture. The per-test one boots a Postgres and a Redis container for every test, which is what the replication tests need and these do not; the sweeper suite alone went from repeated two-minute timeouts to ten seconds.
…eads on The engine's own flows, driven against the decorator with every snapshot read served from Redis, injected through the store seam that runStoreInjectability already proves. Same flows, same expectations, different store underneath — the point is that nothing in the engine has to know, so no existing suite changes. Covers a run driven to completion, the execution data at each step, a since-window wider than the fifty cap, and a pre-cutover run with no keyspace falling back to Postgres. The environment-boundary test asserts parity rather than a fixed shape: whatever Postgres answers for a foreign environment, Redis has to answer the same, or the tenant boundary behaves differently once reads move over.
…oth stores Three defects, all of which passed the existing suites because no test drove a snapshot that actually carried waitpoints, and because the parity suite compared createdAt against a value it had just read back from the row. The decorator never passed a cycle to the append, so no wp:<cycleSeq> key was written for any snapshot and the completed-waitpoint side of Redis was permanently empty. It now mints a cycle when the id set differs from the current head and carries the previous cycleSeq forward when it does not, so a resume writes the record set once and the copy-forwards that follow write no key at all. The since-window hydration returned an empty completedWaitpointOrder. That column is not the join: the engine reads it off the head row as the oracle that gives each completed waitpoint its position in a batch, so an empty order resumed every batched triggerAndWait with an undefined index. Seven of the eight write sites stamped the entry from the app clock while Postgres stamped its own column default, so the two stores held different instants for one snapshot. The decorator now supplies createdAt, and an equal updatedAt, at every site, and the standalone path supplies it too rather than reading the row back. Beyond making the field comparable, this aligns the since-window: the cursor is resolved from one store and applied in the other, and two different instants misfilter that window. The parity suite gains an independent clock-provenance guard, and a case proving an absent instant still takes the database default, which is what keeps the store's behaviour unchanged while the decorator is off.
…oint The generator that emits the pass-through store base is a runnable script, not dead code, and the same glob covers any script added there later.

…arity real The sweep discovered keyspaces by their cur key, which the append script writes only when an entry is valid. A keyspace whose entries all carry an error has no cur and no index, so neither sweep rule could ever see it and it leaked with no expiry, which is the same unbounded leak the second rule exists to close. It now scans on the entry hash, which every append writes, and the age probe falls back to the newest instant in that hash when the index is empty. Enumerating a run's cycle keys used KEYS. That command iterates the whole database and blocks while it does, and a hash tag routes a key without scoping the scan, so a sweep pass would have issued one full keyspace scan per run. It now reads the dense cycle high-water counter the append script maintains, which is the same source the store's own terminal-expiry loop uses, and pipelines the existence checks into one round trip. The timestamp parity assertion was still tautological. The previous commit added a note saying the builders receive an independent instant and did not change the builder calls, which kept reading the value off the row under test. Every case now mints one instant, passes it to the store, and gives the builder the same value, so a write site that stops forwarding the caller's instant fails here. Also documents what an injected fault actually does at each write path, since only the birth path rethrows, and scopes a run count in the chaos suite to the environment under test.

Review asked why the pass-through base is tested against a hand-built delegate rather than a real store. Checking what the compiler already guarantees showed the test's own stated reason was wrong, and that one of its cases could not fail. implements RunStore already rejects a missing member with TS2420, so the claim that a method added later would become a silent hole was not true. The case comparing the class against the generated name list could not detect a parse miss either, because both the class and the list come from one parse of the interface, so a miss drops the member from both sides. The generator's comment asserting otherwise was false. Parity now lives where it can actually fail: assertions tying the name lists to keyof RunStore in both directions, and one rejecting a public member the class declares and the interface does not. They sit in src rather than in a test, because the build config excludes test files, so a type assertion written in a test is never checked. Each was verified by making it fail. What the compiler cannot see is inside the forwarder bodies, since every one is typed (...args: any[]): any. A forwarder wired to the wrong member, or dropping an argument, typechecks cleanly. The remaining probe covers exactly that, using a per-member sentinel so a misrouted body returns the wrong value rather than merely returning something. Verified by rewiring a forwarder: typecheck passes, the probe fails and names the member. Renames the double to forwardingProbe across both suites and says at the top why a container cannot replace it: no database is involved in whether a pass-through passes through.
A member was removed from the generated list while verifying that the new parity assertion fails when one goes missing, and the restore did not run, so the verification state was committed. Regenerated from the interface. The assertion did its job: typecheck rejects the list, naming the missing member.

… client key prefix Two defects from review, both silent. An append staged inside a transaction dropped its expected-head argument, and the post-commit flush passed undefined in its place. That disabled the compare-and-set for every snapshot written inside a transaction, which is the path both engine transaction writers use, so a stale append that the store would have refused as forked was written instead and became the head. The expectation now travels with the staged entry. The sweep built its scan pattern without the client key prefix. ioredis prepends that prefix to keys for ordinary commands but not to a SCAN MATCH pattern, and returns matched keys with it still attached, so a prefixed client made the sweep match nothing and report a clean pass. The engine sets a prefix on every other Redis client it builds, so this would have surfaced at wiring time as a reaper that silently protected nothing. Also removes a keyPrefix option on the sweep that could never work: the keyspace prefix belongs to snapshotKeys in the store, which writes snap: keys unconditionally, so there was no other keyspace to point it at. Both fixes have a test verified by reintroducing the defect: the staged stale append is written without the guard, and the prefixed sweep scans nothing.

… source The generator was scaffolding for a one-off job: writing 70 near-identical forwarders. Keeping it meant carrying a hand-rolled scanner over the interface body, because the TypeScript compiler API is not resolvable in this workspace, which is more machinery than a file that changes only when the interface does. The two files it produced are now maintained by hand, and their headers say so. Nothing is lost, because the generator was never what guaranteed they were right. That is the compiler: implements RunStore rejects a missing member, and the parity assertions tie both name lists to keyof RunStore in each direction and reject a public member the interface does not declare. Each was re-verified by making it fail after the generator was removed. Also drops the knip entry that existed only to treat that script as an entry point.

The sweeper needs to know which run statuses are terminal and cannot import the list, because run-engine depends on run-store rather than the other way round. The copy's comment claimed a parity test kept the two equal. No such test existed, so the claim was false and the copy could drift silently. Drift is not symmetric. A status added to the engine and not the copy makes the sweep treat a finished run as live and never apply its completion expiry. A status removed from the engine and not the copy makes it treat a live run as finished, and that reaps state a run is still using. Verified by removing a status and rebuilding: the test fails and reports seven members against eight.
The forwarders were (...args: any[]): any, so the compiler could not see inside them. A body that called the wrong delegate member, or reordered its arguments, typechecked cleanly. That is not a theoretical gap: it is why a runtime probe existed to catch it, and it is the same shape of hole that let three other defects on this branch pass a green suite. Every member now restates its interface signature and forwards its arguments by name, so both mistakes are compile errors. Verified by making them: a forward to the wrong member produces two type errors, and swapping two arguments produces one. Seven members are overloaded. TypeScript cannot express a single body that satisfies an overload set, so their overloads are declared for callers and their one implementation forwards through a cast. That cast is now the only place the compiler is not checking the forward. The probe shrinks to what is left: those seven casts, a dropped OPTIONAL argument (omitting a trailing tx compiles and silently stops forwarding the transaction), and whether the data property is read live or captured once. Its header states which of those the compiler already covers. Headers on both files now describe what they are rather than that they were once scaffolded.

Sorry, something went wrong.
Typing the forwarders closed the wrong-member and reordered-argument holes but not this one: omitting a trailing OPTIONAL argument still compiles. Two forwarders did exactly that, because the retyping pass read parameter names with a pattern that a preceding inline comment defeated, and both affected parameters happened to be optional and commented. The effects were silent and not small. findLatestExecutionSnapshot stopped applying its tenant scope, so a direct use of the base could read across the environment boundary. upsertWaitpointTag stopped applying its residency hint, so a tag write for a new-database environment would land on legacy. A source-level guard now asserts that every single-signature member forwards exactly the parameters it declares, in order. It reads the interface and the base and compares them, because that property is invisible to the compiler by definition. It carries a vacuity check, so a parse failure fails the suite instead of quietly matching nothing, and that check earned itself immediately by catching a parser that skipped every generic member. Verified: with a parameter dropped again, typecheck reports zero errors and the guard names the member and the missing argument.

A completed waitpoint with no batch index was invisible to every Redis read, so a run resumed from the store lost that wait's result while Postgres still returned it. That is every wait.for, every single triggerAndWait and every token: the engine passes index as batchIndex ?? undefined, so only waits inside a batch carry one. The cause was reading the id set out of the ordered list. That list is the index oracle and its positions ARE the indexes, so it can only ever hold indexed ids, and deduping it yields a set missing exactly the index-less ones. Postgres has no such restriction: its completed-waitpoint join records every id. The cycle key now carries the complete distinct set in its own field, written when the cycle is minted and read back beside the order. The order keeps its meaning and stays index-only. Two tests: one asserting an index-less wait survives a round trip with an empty order, and one asserting the set matches the Postgres join for a mix of indexed and index-less waits. Verified by deriving the set from the order again, which makes the waitpoint vanish. The suites missed this because every earlier case gave each waitpoint an index.

Sorry, something went wrong.
The previous fix stored the complete id set but left three places still deriving it from the ordered list, and the ordered list holds only batch-indexed ids. A carry-forward decided on the order alone. Two DIFFERENT single waits both present an empty order, so they compared equal, the second inherited the first's cycle, and a read returned the wrong waitpoint entirely. The comparison now requires the id set to match as well. The dequeue site built its Redis refs from the ordered list while the delegate connects the complete set in Postgres, so an index-less waitpoint reached Postgres and never reached Redis. Refs are now built from the complete set, with the index taken from the ordered list where the id appears in it. The entry decode derived the set from the order too, which meant getLatest and getById returned an incomplete set. That is the hot read: findLatestExecutionSnapshot hydrates the waitpoint rows from it, so a resume would have fetched no row at all for a single wait. The read scripts now return the stored set alongside the order. Four tests, each verified against its own defect: two consecutive single waits keep separate cycles, a repeated one still carries forward, the dequeue snapshot keeps an index-less id, and the hot read hydrates its row.

A sweep for values derived where they should be read found one more. The hydrated payload left out lastHeartbeatAt entirely, so a Redis-served read returned undefined for it where Postgres returns null. No code writes that column, so null is not a guess: it is the only value Postgres ever holds. The effect was small but constant, on every read served from Redis, and it is the kind of difference a comparator has to either explain or chase. Guarded by comparing the KEY SET of the two payloads rather than their values, so a column omitted by the hydrator fails as a missing key rather than passing as an absent value. Verified by removing the line again: the test names the column. Also covers the timestamp write on both schema variants. updatedAt is declared @updatedat, which Prisma manages, so whether an explicit value survives a create is a property of the client rather than of the schema, and the two variants are separately generated clients. Agreeing declarations were not evidence. Both honour the caller's instant.

An independent pass hunting one shape, a value derived where it should be read, found these. None was reachable from a test that existed. The hot read paid a second Redis call in its most common case. An entry with no wait cycle has no waitpoints by construction, and the hydrator asked the store to confirm that rather than concluding it, on every read of a run that is not resuming from a wait. It now distinguishes the three cases and only asks when it genuinely does not know. decodeWaitpointIds still reconstructed the id set from the ordered list when the stored set was absent. That is the sixth instance of the bug fixed five times, surviving as a fallback. It is unreachable today, because both fields are written by one command, but the reconstruction is lossy by nature and the loss is silent. A missing set beside a non-empty order now reports the entry as not present, which sends the caller to Postgres. The window read checked one liveness anchor where the append script deliberately checks two and explains why. An index lost to eviction while the entry hash survived would have reported an empty hit rather than a miss, so the poll would have returned nothing new for the rest of the run's life while Postgres held the transitions. The wrapped store handle dropped the staging buffer, so a handle taken inside a transaction would have appended before the commit. No caller writes a snapshot through it today. Also restores excess-property checking on the nested snapshot writes. Routing them through a generic helper let a typo'd field name compile and fail at runtime; a concrete parameter type brings the check back at the five sites that pass a fresh literal. Verified: a bogus field is now TS2353.
Two paths reached the same silent hang, and neither had a test. When the store refuses a carried pointer it was still writing the entry, which then became the run's head with no pointer at all. A read of that answers present-with-nothing, and present-with-nothing is precisely the signal that tells the engine's read-repair it does not need to look, so the runner got a waitpoint-less continue and dropped it. Refusing the pointer stays right; the append now mints a fresh cycle from the refs the caller carried, in the same atomic call, so the entry always has a pointer that can be trusted. Refs are optional and only the fallback needs them, so callers that supply none keep the previous behaviour. The second path needs no refusal at all. An entry whose cycle key has gone still carries its pointer, and the read answered empty for it too. That is reachable by eviction and also by the completion expiry, which is applied to every key for a run at one moment but lets them expire independently. Reads now report such an entry as not present, which sends the caller to Postgres, where the join rows still are. The hot read and the window both fall back rather than serve it. Three tests. The refusal is driven at the store, because the decorator cannot reach it on purpose: its probe sees the id set no longer matches and mints a new cycle, so the refusal only happens when the key vanishes between probe and append. Each verified against its own defect.
At that position Postgres holds no snapshot rows, so a run routed away from Redis by the cohort percentage reads nothing at all. The percentage is only meaningful while both stores hold the data. Fixing it in the dial rather than documenting the constraint makes the combination unreachable, instead of leaving three settings that have to agree by convention.

Learning: When reviewing TypeScript in this repo, apply the rule “prefer type aliases over interfaces” only to data/object shapes and union/intersection type modeling. If an interface is being used as a behavioral contract for collaborators to implement (e.g., method-shape interfaces that define required behavior, such as `BackpressureLogger` / `BackpressureSignalSource` in `apps/supervisor/src/backpressure/backpressureMonitor.ts`), keep it as an `interface` and do not flag it as a type-alias-vs-interface violation.

Learning: In this repo’s Vitest setup, `vitest.config.ts` uses `globals: true`, so identifiers like `vi`, `describe`, `it`, and `expect` are available as globals in Vitest test files. During code review, do not flag missing `vi`/`describe`/`it`/`expect` imports as a runtime error or correctness issue when they’re used in `*.test.ts/tsx` or `*.spec.ts/tsx` files. Explicit imports are still preferred for consistency, but they’re not required for runtime behavior.

Summary
Adds a
RunStoredecorator that mirrors execution snapshots into Redis alongside Postgres, plus the orphan-key sweep and the fault-injection suite that prove the write protocol converges after a crash. Nothing constructs it, so merging this changes no behaviour: the configuration, the production wiring and the Redis client all arrive in later work.The execution-state log is the hottest table in the run graph, and moving it out of Postgres has to happen without a big-bang cutover. This is the attachment point for that: a decorator that wraps the existing storage interface and intercepts only the methods that touch snapshots, so none of the many callers change.
Design
Write order is the correctness property, and the two orders differ on purpose.
A transition writes Postgres first and Redis second. A crash in the gap leaves a run whose latest snapshot is stale, which is the state the heartbeat stall watchdog already heals in production today.
A birth writes Redis first and Postgres second. A crash there leaves an unreachable key for a run that does not exist. Postgres first would instead leave a run with no snapshot at all, which the engine treats as a hard error, so the run would be stuck.
Each order is chosen so the state a crash leaves behind is the harmless one. A lost cross-store write is never recovered by a transaction or an outbox; recovery is always the existing stall and repair job. A failed append retries, then hands the run to that job, and never rethrows, because Postgres has already committed and a throw would turn a healable gap into a caller-visible error.
Inside a transaction the Redis half is staged and flushed only after the commit, so a rollback cannot leave Redis holding a transition that never happened.
Reads are shape matched. Two of the snapshot reads take arbitrary Prisma arguments, and a key-value store cannot answer an arbitrary query, so the decorator recognises exactly the shapes the engine sends and delegates everything else. A miss falls back to Postgres, which is also how runs created before any cutover keep working.
The sweep reaps under two rules, because neither can see what the other leaves behind. A finished run whose keyspace never received its completion expiry gets one applied. A keyspace with no run row at all, past an age threshold, is deleted; that is a crashed birth, which is non-terminal so it carries no expiry and has no run row, so the first rule can never match it.
Inertness
Three independent reasons this is a no-op if merged alone:
Notes for review
The snapshot id and the creation instant are both minted by the decorator and written into both stores, so one snapshot has one identity and one timestamp wherever it is read. Without that, the two stores disagree on values that later tooling has to compare, and the cursor for a snapshot window resolved from one store misfilters the window walked in the other.
Three defects in this work passed the full existing test suites before being found by review rather than by a test: the decorator wrote no wait cycle at all, the snapshot window dropped the ordering used to give each completed waitpoint its position in a batch, and the two stores stamped different creation times. The common cause was that no test drove a snapshot that actually carried waitpoints, and that the parity suite compared a timestamp against a value it had just read back from the row it was checking. Both gaps now have tests.
