   Session: session_017ihL2c5z3q4h8inrn5kwqV (epic PM); implementing card thread session_017ihL2gRrVctbMWaHbABDch
   Account: marchtian
   Branch: claude/project-thread-wj01ct (the card thread's platform-assigned branch — measured platform exception to claude/issue-<n>-<slug>)
   Worktree: objectstack-issue-27741
   Domain: domain:server
   Seat: epic:#27261#1 (epic PM; no domain:* seat). Maintainer order, 田騏 2026-10-29T21:58Z: 「现在启动全部 P2」; 2026-10-29T21:59Z 「OData 驱动 只做 v4」
   File surface: packages/drivers/driver-odata/** (new package), the server plugin that publishes driver.odata, workspace wiring the new package needs (pnpm-workspace.yaml / root configs / lockfile), .changeset/** (stop on breach, including any packages/spec/src/** or DRIVER_VOCABULARY edit; explain in the report)
   Container & model: L, mode:thread, model: default tier (dispatch-gates --tier: no path-derived mandate), effort: high
   Clause-②: no
   Metadata-protocol: none
   Responsibility: epic #27261 P2 (ruling 6486145005, letter B); the engine floor from #27277 is the correctness net it relies on
   Thread-read: none
   Premise: holds — on origin/main no OData driver exists (packages/drivers: memory, mongodb, sql, sqlite-wasm, turso), and needsExternalDriverFloor floors any non-built-in driver id on a non-managed datasource.
   Serial constraints: #27745 and #27747 are Blocked-by this card. #27742 / #27746 (D7) are not; use credentialsRef auth only here.

New package @objectstack/driver-odata (fixed group, 18.2.0): createODataDriverPlugin publishes ODataDriver as driver.NAME (default driver.odata), a plugin driver id; DRIVER_VOCABULARY and packages/spec/src untouched. Config contract (strict zod, parsed at plugin build): name, serviceRoot (http/https, refused with userinfo or query), version 4.0, auth none|bearer|basic(username), pageSize, requestTimeoutMs; no credential key. Credential = the datasource's external.credentialsRef, read from engine.listDatasourceDefs() and resolved through options.secrets (the host's SecretBinder read half) at the first request, re-resolved once on 401; fails closed on missing ref, missing store, unresolvable handle, undeclared datasource, ref under scheme none. Reads: $filter/$orderby/$select/$top/$skip, @odata.nextLink (same origin only), key appended to $orderby on paged reads, count via $count=true only when the where translated completely. Translator never narrower: $not never pushed, $ne/$nin on nullable carry 'or P eq null', text only eq/in/contains/startswith/endswith/ASCII icontains, unspellable comparands left to the floor. ReadableIds leaves refused by the driver itself (readableIdsDriverRefusal). Writes POST/PATCH/DELETE by key with If-Match from the last read's @odata.etag, declared properties only; upsert/bulk/transactions/execute/dropTable refused by name (400). introspectSchema: entity sets, EDM types, keys, single-valued navigations with bound set as lookup candidates (for #27745). Dialect seam: ODataDialect (headers, envelope, etag, error body, CSDL reader, literals, functions, in-list, count option); only odataV4Dialect ships. Two files outside the claimed surface, both mechanical consequences of a new published package: packages/spec/llms.txt package count 72 to 73 (check:llms-txt red otherwise; spec patch added to the changeset) — not packages/spec/src. D7 (#27746) case: not on main at bcc0a1a3 (git grep of origin/main packages/types/src for a connector-credential seam: 0 hits), so not wired; the auth header comes from one function, ODataTransport.authorization() in transport.ts, fed by the plugin's credential() source in plugin.ts — the later wiring replaces those two.",

Suites: filter.test.ts (54-row translation table), dialect-v4.test.ts (CSDL reader + envelope), odata-driver.test.ts (recorded TripPin-shaped service: reads, paging, writes, ETag, keys, introspection, credentials), odata-driver.floor.test.ts (real ObjectQL engine + floor, objects bound by engine.syncSchemas: in-memory application of $like, count through floor, 400 read = INVALID_QUERY, 400 write = EXTERNAL_WRITE_REFUSED 422, 503 withheld), plugin.test.ts (service name, config refusals, bearer/basic, 5 fail-closed), odata-driver.conformance.test.ts (all 11 shared case-sets, 326 cases, through engine+floor over an in-process OData service that evaluates the $filter, read sets under ordinal and case-insensitive collation).

   PR #27796 merged through the queue as 0a4b0fb223 on 2026-10-30T01:32:02Z (head 7f91132b; seat ACCEPT 6512051940, the review of record for a no-contract-face PR; APPROVED by os-zhuang past the 3000-line gate). @objectstack/driver-odata is on main: a declarative OData v4 driver published as the plugin driver id driver.odata, held behind the engine floor, with a v2 dialect seam. Follow-ons: #27798 (#27744) adds the driver-odata test that runs the conformance kit; #27819 (#27746) wires the D7 connector credential into ODataTransport.authorization()'s source; #27745 ($metadata import) and #27747 (guide) are unblocked and dispatched next.
