Add an ESLint plugin for oracle files (scripts/eslint-plugin-oracle/) with the oracle/no-disabled rule. It reports `.only`, a `.skip` or `.todo` that switches off a body, `.skipIf`/`.runIf` conditions that name no replay, Playwright's unconditional runtime skips, and generated properties limited to one unpinned run. The rules have no inline exception. scripts/agent-lint-feedback.mjs runs the oracle rules in a pass that ignores inline directives, so an eslint-disable comment cannot silence them. It serves the Claude Code, Codex, Gemini CLI, and Copilot hooks after each edit and at the end of a turn, `pnpm lint:changed`, `pnpm lint:oracles` in CI, and the pre-commit hook. Pre-commit ESLint now runs in chunks to avoid running out of memory on large commits. Remove the skipped random campaign for the #2139 known gap; the fixed-seed `it.fails` cell still pins it, and its replay name is unregistered so a replay request fails loudly. Refs #2234 Co-authored-by: Isaac <no-reply@databricks.com>
Replace the rule's "names a replay" heuristic, which wrong-branch conditionals, inverted conditions, the node:path module, and environment seeds all passed. A one-run options object now needs a `path` (a recorded counterexample) or a seed that is a number literal or a constant bound to one. `skipIf` accepts only `oracleReplayRequested()` from oracle-config, and `runIf` is always reported. The rule also reports Playwright `fixme`, context skips such as `ctx.skip()`, and runtime skips other than `browserName !== '<browser>'`. oraclePropertyOptions now returns one run for a path replay, so six campaign sites drop their own one-run conditional. The OPFS diagnostics oracle uses the shared replay variables, and the replay calibration fixture overrides its run count after the replay options are chosen. The enforcing pass lists tracked oracle files with git, so it skips untracked worktrees, and it fails when no main branch is available to compare against. CONTRIBUTING.md states that lint:changed runs only the oracle rules. Stale prose about the removed replay name is corrected. Refs #2234 Co-authored-by: Isaac <no-reply@databricks.com>
The previous commit made oraclePropertyOptions run a path replay once. utils.test.ts still expected the base run count for the named property. Refs #2234 Co-authored-by: Isaac <no-reply@databricks.com>
Address CodeRabbit's review of 012f406: - oracleReplayRequested() means a path replay. A seed without a path only reseeds the random campaigns, so fixed tests keep running. - The OPFS diagnostics oracle takes its replay and random options from oraclePropertyOptions, so a path replay runs once and a seed-only run reseeds only the random campaign. - oracle/no-disabled accepts skipIf(oracleReplayRequested()) only when the helper is imported from oracle-config, so a local function of that name does not pass. - The context-skip check resolves the binding through scope, so a context captured by a nested callback is reported and a shadowing variable is not. Refs #2234 Co-authored-by: Isaac <no-reply@databricks.com>
oracle/no-disabled now requires every replay selection to go through the shared oracle-config helpers, so a selection cannot switch an oracle test off in an ordinary run: - A test modifier used as a value (`replaying ? it.skip : it`) is reported. oracleReplayTest(registration, ...properties) selects a replay instead. - A test registered under a condition, or after an early return, is reported unless the condition is oracleReplayRequested() or oracleReplaySkips(...properties), or a negation of one. An early throw fails loudly, so it guards nothing. Calls such as Playwright's test.info() are not registrations. - skipIf accepts oracleReplaySkips(...properties) as well. - A one-run path must be recorded: a literal, or a failure's counterexamplePath. A replay from configuration uses oraclePropertyOptions. - A literal run count above 1 that pins no history is reported, because it does not scale with TANSTACK_DB_ORACLE_RUNS_MULTIPLIER. oracle-config gains oracleReplaySkips and oracleReplayTest, both of which accept several properties. The registry adds the names that the migrated oracles select: numbered utils and comparison families, IndexedDB cross-tab history, OPFS diagnostics, and the package oracles that had their own replay variables. Refs #2234 Co-authored-by: Isaac <no-reply@databricks.com>
Move each oracle's replay selection onto oracleReplayRequested, oracleReplaySkips, oracleReplayTest, and oraclePropertyOptions, so the extended oracle/no-disabled rule passes everywhere. In an ordinary run, every file runs the same tests with the same seeds and run counts; literal run counts are wrapped in oracleRuns, which equals the count at multiplier 1. Replay changes: - Oracles with their own replay variables now use TANSTACK_DB_ORACLE_SEED, _PATH, and _PROPERTY: utils (utils.N), comparison (comparison.N), IndexedDB cross-tab history, db-ivm index refinement, offline KeyScheduler, Electric history and pg-serializer, SQLite core adapter, Node expression index, and op-sqlite. ORACLE.md and the coverage map show the new replay commands. - A seed without a path reseeds random campaigns and keeps fixed ones, matching the shared semantics. - Some fixed or unit tests now stand aside during any path replay, where they used to run during some replays. - Calibration witnesses register through oracleReplayTest and keep TANSTACK_DB_ORACLE_CALIBRATION as their fault switch. Other changes: - The replay guard's calibration fixture is renamed to replay-guard-calibration.fixture.test.ts. It is a fixture, not an oracle. - The includes transition matrix registers over a filtered table, not under `continue`. - The PowerSync correctness oracle now fails loudly when no SQLite binding loads, where it used to skip itself silently.

the random-seed campaign unchanged so both campaigns respect the configured run
multiplier.

- Around line 96-97: Update the fresh campaign flow using oraclePropertyOptions
so its calculated numRuns is passed through campaign and into the runCampaign
options, rather than using the unmodified runs value; preserve the existing seed
and path handling.
Review comments at @scripts/eslint-plugin-oracle/rules/no-disabled.js:
- Around line 416-418: Update guardingConditions and its use of
isReplayCondition so negated replay conditions are rejected when they guard an
early exit, while remaining valid in enclosing registration branches. Add an
invalid regression test for the early-exit form and keep positive-polarity
early-exit guards and negated enclosing branches valid; clarify the header
comment to distinguish these cases.

Address the medium code review and CodeRabbit's review of 95c16bb: - oracle/no-disabled checks a registration made through oracleReplayTest or oracleCalibrationTest as a registration of its test, so `.only`, `.skip`, `.skipIf`, and guards through the helper are reported. - A guard is accepted only when the test registers while the replay helper is false: under `!helper()`, in the `else` of `helper()`, or after `if (helper()) return`. A test that registers only during a replay is reported, and so is `if (!helper()) return`. - `continue` and `break` filter a loop's data, so they guard nothing; the two loop rewrites they forced are reverted. - The numRuns exemption matches only packages/db/tests/oracle-config.ts. - Replay-only lanes in the Electric, pg-serializer, SDK delivery, descriptor isolation, and includes-optimistic oracles become fixed and random campaigns through the shared helpers. - oracleCalibrationTest skips a calibration witness during a replay without its fault, where it used to pass without checking anything. - readOracleRunConfig rejects retired replay variables, so an old replay command fails instead of running the full campaigns. - The interruption-settlement oracle uses the shared replay variables, and the offline config no longer accepts TANSTACK_DB_OFFLINE_ORACLE_*. - The replay manifest names owners for the new replay properties, and its owner check covers the numbered utils and comparison families. - Fixed-campaign run counts scale with the multiplier in the queued-presence, binding-capacity, and IndexedDB cross-tab campaigns. - Comments and the coverage map describe the shared replay variables.

Include the run-count setting in the retired-variable error.
readOracleRunConfig rejects retired run-count variables, but the error only names replay selectors. TANSTACK_DB_ORACLE_RUNS_MULTIPLIER scales oracle run counts. Add it to the guidance.

🎯 Changes
This PR closes the gaps that #2236 left in
oracle/no-disabled. Every oracle now selects its replays through the shared helpers inpackages/db/tests/oracle-config.ts, so the rule can see each way to stop an oracle test. It follows #2236, which is merged, and is step 3 of #2234.In #2236, the rule could not see these forms:
Now the rule reports each of them, and the oracles use the shared helpers:
The law
An oracle test may stop running only while a path replay selects another test. Each shared helper is false in an ordinary run, so no replay selection can switch an oracle test off there:
oracleReplayRequested(): a path replay is selected.oracleReplaySkips(...properties): a path replay of a property outside the list is selected.oracleReplayTest(registration, ...properties): the registration'sskipform while such a replay runs, and the registration itself otherwise.oracleCalibrationTest(registration, property, fault): the same for a calibration witness. It also stands aside during a replay of its property without its fault, selected byTANSTACK_DB_ORACLE_CALIBRATION.oraclePropertyOptions(base, property): the run options. A path replay of the property runs once, from its seed and path. A seed without a path reseeds the random campaign.What the rule reports now
replaying ? it.skip : it.return. The rule accepts a guard only when the test registers while a shared replay helper is false. The accepted forms are!helper(), theelseofhelper(), andif (helper()) return. Each helper is false in an ordinary run, so such a test runs there. A test that registers only during a replay is reported.throwfails loudly, andcontinuefilters a loop's data, so neither guards a registration. Calls such as Playwright'stest.info()register nothing, so the rule ignores them.oracleReplayTestororacleCalibrationTestgets the same checks as a direct registration..skipIfwith any condition other thanoracleReplayRequested()ororacleReplaySkips(...).paththat is not recorded. A recorded path is a literal or a failure'scounterexamplePath.TANSTACK_DB_ORACLE_RUNS_MULTIPLIER, sooracleRunsmust wrap it.The helpers must come from the

A local function with the same name does not pass.packages/db/tests/oracle-config.tsitself may set a path replay from configuration, because it implements replay selection.readOracleRunConfigrejects the retired replay variables, such asUTILS_ORACLE_SEED. An old replay command fails with an error, and does not run the full campaigns and pass.Migration
The extended rule found 153 sites in 45 oracle files. Every site now uses the shared helpers. In an ordinary run, each file runs the same tests with the same seeds and run counts.
oracleRuns(n)equalsnat multiplier 1.These oracles had their own replay variables. They now use
TANSTACK_DB_ORACLE_SEED,TANSTACK_DB_ORACLE_PATH, andTANSTACK_DB_ORACLE_PROPERTY:utils-oracleandcomparison-oracle, as the registered familiesutils.Nandcomparison.Nin file order. A replay of an unregistered number fails withunknown oracle property.indexeddb.cross-tab-history).packages/db/tests/indexed-db/ORACLE.mdshows the new command.The registry adds the
utils.Nandcomparison.Nfamilies,indexeddb.cross-tab-history,offline.interruption-settlement, and 45 names for the package oracles. The replay manifest names an owner file for each new property, except two (see Limits).Some files use one helper for several properties. For example,
persisted-oracle.test.tsruns a suite during replays of three properties.oracleReplayTest(describe, a, b, c)keeps that behavior in one line, so the file does not re-indent.Other changes

The documented witness still gives its main-property failure at checkpoint 0.replay-guard-calibration.fixture.test.ts. It is a fixture, not an oracle, so the oracle rules do not apply to it.node:sqlite.Replay behavior that changes

They record the commands as they were then.OFFLINE_ORACLE_*replay variables. They are consistent among themselves. A later change can move them to the shared variables.main, and forsqlite-persistence.binding-capacityandsqlite-resume.baseline-lineage. Those two run through a host file that does not name them.🔬 Oracle Coverage
This PR changes no production code and no oracle law. It changes test registration, replay selection, and run-count plumbing. No model, generator, comparison, or assertion changes. The calibration witness keeps its assertions. It returns early only during a replay of its property without its fault.
