Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The PR adds opt-in dbt completion gates, but the current implementation can still skip required validation for Python models and certain task-file layouts, falsely block valid incremental or dialect-guarded SQL, and accept a required deliverable after session-authored configuration exempts it from successful-build coverage. These bounded correctness and test-isolation issues should be fixed or explicitly accepted before enabling the gates broadly. Sequence Diagram(s)sequenceDiagram

- Around line 164-166: Update the wiring plan to distinguish lint-rule and
bespoke-analysis implementations: for a lint rule, reuse the existing
altimate_core.lint path and require only a validator consuming its results;
reserve a new NAPI export and dispatcher entry in altimate-core.ts for the
bespoke API alternative.
In `@packages/opencode/src/altimate/validators/dbt-build-green.ts`:
- Line 159: Update the validation flow around modelNodeNames and notBuilt so
test-only run_results.json cannot produce a successful result for an edited
model without build evidence. Require either a matching model-node build result
or separate successful build evidence before returning ok: true, while
preserving the existing behavior when valid model build evidence is present.
- Line 124: Update readRunResults so statusByName only stores entries whose
uniqueId starts with "model.", preventing test results from colliding with model
names; leave other result handling unchanged.
- Line 87: Extend modelsModifiedSince and modelNameFromPath to recognize Python
dbt model files with the same edited-model behavior as SQL files, ensuring
DbtBuildGreenValidator.check() gates appropriately when a .py model changes. Add
a test fixture covering a modified Python model path.

End-to-end evidence on real dbt projectsI ran these five against real dbt projects rather than fixtures, and wrote the results up in Read this first: the A/B is N = 1. The planned run was 10 tasks × 2 arms × 2 rollouts = 40 sessions. Three completed — one paired task plus one unpaired control arm — before the batch was stopped for machine capacity. No conversion claim can be made from that, in either direction. The safety numbers below are not affected: they come from deterministic probes that run the validator code paths directly against real project states with no model in the loop. Safety: 5 false positives across 38 known-good statesProjects: 10 real dbt projects with golden-output graders (workspaces copied, never mutated), plus a fresh clone of Across 27 naturalistic known-good end-states — project authored and built green, build-only sessions, read-only sessions, a new model added correctly, a correctly-configured incremental model — zero firings. That part of the conservative design holds up. Across 11 constructed known-good states, each an ordinary dbt practice, five fired. All reproduce deterministically:
Per-validator: Detection: 8 of 11 known-bad states firedRed build, models-edited-with-no-artifact, a required deliverable that does not exist, an unguarded The three silent ones trace to one thing: Negative control: cleanLive session in a small TypeScript repo, Zero executed, no synthetic message injected. The gate is inert outside dbt even with the most aggressive opt-in set. Cost~1–2 ms per validator, mean 10 ms per dispatch on small projects. On a synthetic 2005-model project it is ~1–3.5 s per dispatch — paid even when the session touched nothing, because each validator runs its own independent tree walk with no shared work. Worth a shared scan if this goes wide. One observation from the single enforced session

The design is sound, the true-positive behaviour is real, the cost is trivial on normal projects, and all five false positives look like small contained fixes rather than anything structural. But the benefit side is genuinely unmeasured, and I would not want the first real signal to be retry budget burned on ephemeral models. Rough order I would suggest: fix the five (adding those states as regression tests — they are a few lines each), widen the verb list, decide on the One thing outside this PR's scope but relevant to any enable-by-default decision: that flag turns on all seven registered validators.

Review dispositionEvery inline comment and review body on this PR (61 inline comments across cursor, coderabbit, cubic, kilo-code and codex, plus the review summaries) was collected and de-duplicated into 38 distinct findings. Alongside them, an end-to-end run against real dbt projects — not fixtures — reproduced five false positives across 38 known-good states and one case where the central gate returned green having checked nothing. Those empirical findings were treated as higher priority than the speculative ones, and several of the bot findings turned out to describe the same defects. Everything actionable is in Counts: 24 fixed · 3 already correct · 7 deferred · 4 declined. Fixed — false positives that blocked healthy sessionsThese are the ones that mattered. A gate that fires on a finished session costs a synthetic retry turn for nothing, which is strictly worse than not shipping the gate. Each has a regression test asserting no firing on the known-good state.
Fixed — the silent no-op, and leniency holes
Fixed — tests that did not test what their names claimedThree of these were caught by reviewers and are worth calling out, because a test that passes for the wrong reason is worse than an absent one.
Already correct
Deferred — real, but larger than a fix-in-placeRecorded with full rationale in
Declined — the conservative behaviour is intended
One thing the fixes do not establishFixing five observed false positives does not bound the false-positive rate — 38 known-good states is a sample, not a proof. And there is still no conversion evidence in either direction: the A/B reached N = 1 paired task before it was stopped for machine capacity, and that pair needed no retry, so there was nothing to convert. The PR body now carries the shadow-mode-first recommendation and the honest limits behind it. |

… commit itself introduced or left exposed The bot reviewer (chatgpt-codex-connector) re-scanned 3d2f6e9 and found five new P1s plus one P2, all genuine — four are sibling code paths the third sweep's fixes did not reach, and one (materialized-value handling) is an actual regression the top-level config rewrite introduced. Fixed all six with an adversarial test that fails against 3d2f6e9. - `dbt-incremental-config`'s `unique_key`/`incremental_strategy`/ `materialized` detection now goes through the same top-level config parser (`readIncrementalTopLevelConfig`, built on `parseTopLevelConfigAssignments`) as `dbt-build-green`'s exemption reader — it was still scanning the whole `dbtConfigArgs` blob, so a hook string containing the literal text `unique_key='id'` could forge a real key and silently permit an upsert with no way to dedup rows. - `dbt-build-green`'s failed-row scope set (`inScopeIds`/ `inScopeBareNamesFallback`) now matches by full manifest identity first, same as the status lookup added in the prior commit — the failure- classification path had kept the old bare-name `inScope` set, so a dependency's failed `orders` could still block a correctly built local `orders` on an unrelated package failure. - `RequiredDeliverables` gained `modificationFiles`, the file-path counterpart to `modificationModels` — "Update the file `models/schema.yml`" names a file, never a model, so the modification signal for it had nowhere to land. `dbt-nothing-built` now requires authorship for a file in that set instead of accepting pre-session existence. - `sanitizeTelemetryDetails` now also redacts every string under a small, exhaustive set of keys documented to carry a path (`required_files`/`missing_files`/`task_file`/`task_files`/`dbt_root`/ `run_results_path`), not only strings shaped like an absolute path — a task-derived RELATIVE path such as `models/private_customer_rollup.sql` was passing straight through the absolute-path-only heuristic. - Fixed the regression: `readConfigAxes`'s `materialized` check now only treats a value as a static ("not ephemeral") declaration when it is literally a quoted string (`staticQuotedLiteralValue`) — the third-sweep version read ANY non-`'ephemeral'` value, including a dynamic `materialized=var('kind', 'ephemeral')`, as an affirmative non-ephemeral declaration, which overrode a correct manifest exemption and demanded a `run_results` row dbt was never going to write for a genuinely ephemeral model. - P2: a task's idempotency demand is now scoped to the model named inline (`Make \`orders\` idempotent`) rather than applied workspace-wide to every incremental model the session touched, so a separate, intentionally append-only model is no longer wrongly blocked. A demand with no named model stays workspace-wide, unchanged. New tests in `test/altimate/validators/review-sweep-4.test.ts` (13 tests, one file per fix); confirmed to fail against 3d2f6e9 via a temporary `git stash` before restoring. `bun test test/altimate/validators/` green (791 pass), typecheck clean, marker check clean against origin/main.

Real. Deliberately not fixed in this pass — hard stop on the review-round chase after fixing the one trust-critical false positive from this same round (see the sibling threads on dbt-nothing-built.ts:315). This is an instance of the same duplicated-heuristic category (dbt-incremental-config's idempotency-scope parsing re-implements code-span/verb classification independently of extractRequiredDeliverables rather than sharing it) that the false-positive fix's evidence documents. Recorded as round-4 deferred item 1 in .github/meta/deterministic-validators-followups.md's new REQUIRED-precondition section (b97c58a): enforcement mode is now explicitly gated on consolidating these heuristics, with this finding as part of the concrete list to close against.

When an earlier document has a satisfied creation contract and a later one requests a modification—for example, TASK.md says to create the already-present foo while REQUIREMENTS.md says to update the already-present bar—this immediate return retains only foo. A zero-write session then passes this gate because foo exists, while dbt-deliverable-names also passes because it checks existence rather than modification evidence, so the requested update to bar is never enforced. Aggregate the requirements and modification subsets from all discovered task documents here as well.

When one task requests updates to multiple existing models or files, this succeeds after only one requested item has session evidence because it tests matchedDeliverables.length > 0. For example, after updating/building only foo from Update the models fooandbar``, bar is accepted by the name validator merely because it already exists, so the untouched update is not caught by any gate. Require every member of the modification subsets to have authorship/build evidence rather than accepting the first match.

Fresh evidence beyond the status and failure identity fixes is that manifest exemptions are still looked up by bare name. If a dependency defines an ephemeral or disabled orders while the root project has an ordinary edited orders, the dependency adds orders to this set and these lines drop the local model from states; even a fresh error row for model.root.orders is then counted out of scope and the validator returns exempt-only. Associate exemptions with the touched file's own manifest unique_id, just as status matching now does.

Real, and specifically called out — this is the third instance of the bare-name-vs-full-identity gap in dbt-build-green.ts alone (status lookup and failure classification were both moved to full manifest identity in this pass; the manifest-exemption lookup was not). Deliberately not fixed now — hard stop on this round after closing the one trust-critical false positive. Recorded as round-4 deferred item 6 in .github/meta/deterministic-validators-followups.md (b97c58a), explicitly cited as evidence in the new REQUIRED precondition: enforcement (ALTIMATE_VALIDATORS_ENABLED=1) is now gated on consolidating this exact matching logic into one shared primitive rather than a fourth per-validator copy.

When the task identifies the model by path, such as Make the model models/orders.sql idempotent, this stores models/orders.sql as the scoped model while the later lookup compares it with the bare name orders. The demand is therefore recorded but never applied, and a touched append-only incremental model without an is_incremental() guard passes. Convert path-shaped spans to their model stem before adding them, or distinguish actual model tokens from other inline code spans.

When a required path inside the workspace is a symlink to a file outside it, this lexical prefix check accepts the path and both file-existence callers use fs.stat, which follows the link. A pre-existing link such as reports/output.yml -> /tmp/unrelated.yml can therefore satisfy both contract gates even though the implementation explicitly intends to reject artifacts outside the allowed roots. Check the resolved realpath against the root realpath, or use lstat and reject escaping symlinks before testing existence.

When a touched BigQuery model uses a valid # line comment containing a curated function name, such as # safe_cast(...), this lexer leaves the entire comment visible because it recognizes only -- line comments. dbt-dialect-guard consequently reports the commented text as an unguarded warehouse-specific call and blocks otherwise valid work; the same omission can also contaminate the incremental lint's SQL scan. Treat # through the end of the line as a comment for dialects that support that syntax.

…ot re-scan found Third consecutive round of bot re-review on this fix chain (chatgpt-codex-connector + Kilo). All six are real; fixed with an adversarial test confirmed to fail against 677b00b. - `collectProducedNodeNames`'s manifest loop now excludes nodes whose `original_file_path` sits under `sourcePaths.packages`, closing the same dependency-node collision `dbt-build-green` and `dbt-incremental-config` were already fixed for — an installed package's own `orders` model could satisfy a required root-project `orders` with zero session work. - `dbt-nothing-built`'s authored-work scan now only contributes a name to the relation index under the extension dbt actually loads for that directory kind (`.sql`/`.py` for models/snapshots, `.csv` for seeds) — writing an inert `models/orders.txt` no longer counts as authoring the `orders` model. - `dbt-deliverable-names`'s own `contract.taskFile` interpolation into `fixHint` is now sanitized — the sibling `unrequested` interpolation was fixed two commits ago, this was the same gap on the file's own task-file path. - New `dbtConfigCallArgsUnconditional` excludes a `config()` call sitting inside a runtime-dependent `{% if %}` (`target.name == 'dev'`) from the ephemeral/enabled EXEMPTION axes specifically — `dbt` resolves such a condition against the actual profile target, which this source-level scanner cannot know, so trusting it either way is a guess; a fresh `error` row for the model's real, active config can no longer be waved through as out-of-scope. Deliberately scoped to the exemption axes only — `dbt-incremental-config`'s inconsistency checks still use the unrestricted `dbtConfigCallArgs`, where a conditionally-declared key is still useful signal. - P2: idempotency demand recognition now treats "is optional" / "not required" / "not necessary" / "advisory" (before or after the keyword) as a disclaimer, same as the existing negation forms — "Idempotency is optional for the `events` model" no longer forces a guard onto a correctly guardless model. - `resolveWithinRoot` (Kilo suggestion) now resolves the REAL path of the candidate's containing directory, not just the lexical one, before the containment check — a symlinked directory inside the allowed root pointing outside it (`models/` -> `/etc`) passed the lexical `startsWith` check while the caller's `fs.stat` followed the symlink out. Falls back to the lexical result when realpath fails (path doesn't exist yet), matching the existing fail-open-to-"unmet" behaviour for that case. Now async; both call sites updated. New tests in `test/altimate/validators/review-sweep-5.test.ts` (15 tests); confirmed to fail against 677b00b via `git stash` before restoring. `bun test test/altimate/validators/` green (807 pass), typecheck clean, marker check clean against origin/main.

Fresh evidence beyond the prior run-results identity fix is that the independent <target>/run evidence remains keyed only by basename: when local orders.sql is touched but only model.dependency.orders is run, the dependency's fresh target/run/dependency/.../orders.sql makes executed.has("orders") true. The local state has no status row, yet this removes it from notBuilt and the validator returns ok: true with build-unproven; associate compiled DDL with manifest unique IDs before accepting it as coverage.

When a task says Update the model orders, the local orders.sql is untouched, and the session runs only a dependency's same-named model.dependency.orders, this bare-name insertion makes the dependency result count as session evidence for the requested modification. dbt-nothing-built then passes, the name gate accepts the existing local file, and build-green sees no touched local model, allowing a zero-write response; retain the package-qualified ID and match it to the root project's node.

Fresh evidence beyond the single-negated-verb fix is that a compound line such as Create the model new_orders; do not create the model legacy_orders`` checks negation only for the first Create and then collects both code spans. Both contract gates consequently require `legacy_orders` to exist, permanently rejecting the correct implementation that omits it; split the line into verb clauses or associate each span with its governing verb and negation.

When valid YAML places an unindented comment between a path key and its sequence, such as model-paths: followed by # project models live elsewhere and then - transform, this non-item branch treats the comment as the end of the sequence and returns null. resolveDbtSourcePaths consequently falls back to models/, so touched-model validators miss edits under transform/ and the deliverable validator can report models there as absent; ignore comment-only lines before applying the indentation termination rule.

When a session successfully runs dbt build and then runs dbt compile or dbt docs generate, the later command overwrites run_results.json with a fresh non-executing artifact while the successful build's fresh DDL remains under <target>/run. This condition marks the artifact non-fresh for gating and returns non-executing-artifact before the DDL evidence is inspected, so a correctly built model is blocked and unnecessarily told to rebuild; consult the session-fresh DDL evidence before hard-failing solely on the last command.

Restrict the `optional`/`advisory` disclaimer to when it directly qualifies the idempotency concept (e.g. only in the AFTER "idempotency is optional" form), or narrow their before-window to 0-1 words, instead of reusing the 2-word window meant for negations like "not necessarily".</violation>

P2: When optional or advisory modifies an unrelated noun within two words before the idempotency word, the line is treated as a disclaimer and the idempotency demand is dropped. For example "Make the optional model idempotent" matches optional + the 2-word window and is skipped, so a correctly-guarded requirement is never enforced and a guardless model passes the missing-guard check. Restrict the optional/advisory disclaimer to when it directly qualifies the idempotency concept (e.g. only in the AFTER "idempotency is optional" form), or narrow their before-window to 0-1 words, instead of reusing the 2-word window meant for negations like "not necessarily".

…n a consolidation refactor Hard stop on the bot-round chase (Anand's call): fix the one trust-critical false positive from round 4, record the recurrence pattern as a REQUIRED precondition for enabling enforcement, and stop iterating on further rounds. The false positive: `dbt-nothing-built`'s modification-file tracking (added two commits ago) skipped the existence check entirely for any file tagged as a modification target, so a required file OUTSIDE the scanned dbt source paths (`reports/output.yml` — `authoredWork.relPaths` only covers models/seeds/snapshots/analyses/macros/tests plus a small root-file allowlist) could never satisfy its contract, even when the session genuinely edited it this run. Fixed by falling back to an mtime check (`>= sessionStartMs`) for exactly that case: a fresh mtime is genuine session evidence even for a path `authoredWorkSince` never scans; a stale one still correctly fails, same as before. `dbt-deliverable-names.ts:315` (cubic + chatgpt-codex-connector, same root cause, two threads) closed. Also records the durable finding round 1-4 produced: the SAME five heuristics (bare-name-vs-full-identity matching, extension/source-dir filtering, package exclusion, conditional-config resolution, file-vs-model modification tracking) were each duplicated across 2-3 validators independently, and every duplication round found a fresh instance of the same bug in a sibling copy — this false positive being the direct consequence of one such copy. Added a REQUIRED precondition to `.github/meta/deterministic-validators-followups.md`: enforcement (`ALTIMATE_VALIDATORS_ENABLED=1`) must not ship beyond a shadow-mode soak until those five heuristics are consolidated into shared, tested primitives. Default-off and shadow remain fine to ship now. Mirrored as a code comment at the `ALTIMATE_VALIDATORS_ENABLED` read in `session/prompt.ts`. The 9 round-4 findings not covered by the false-positive fix are recorded in the same followups section as the concrete list for that consolidation work to close against — deliberately not fixed here, per the hard-stop decision. New adversarial tests in `review-sweep-5.test.ts` (3 tests): the FP case (now passes), the still-correctly-blocked pre-existing/untouched case (unaffected), and the create-contract case (unaffected). Confirmed to fail against the pre-fix code via `git stash` before restoring. `bun test test/altimate/validators/` green (810 pass), typecheck clean, marker check clean against origin/main.

When materialization varies by target, such as an inactive {% if target.name == 'dev' %} arm declaring keyless incremental/merge and the active else arm declaring table, this loop merges both arms: isIncremental remains true and strategy remains merge, so the validator blocks a correctly configured table model. Restrict blocking checks to unconditional config calls or resolve the active node configuration from the manifest.

When dbt_project.yml configures macro-paths: ['jinja'] and the task says Create the file jinja/generate_dates.sql``, this directory-name heuristic also derives a required model named generate_dates. The file check succeeds, but the produced-node inventory correctly excludes macros, so `dbt-deliverable-names` permanently blocks the valid macro-only implementation. Classify the path using the project's configured source directories, or preserve the requested resource noun instead of assuming every unrecognized SQL directory produces a model.

Fresh evidence beyond the earlier dollar-quote fix is that valid PostgreSQL-style tags may contain digits after their first character, for example $body1$ iff(a, b, c) $body1$, but this pattern accepts letters and underscores only. The literal body therefore remains visible to dialect matching and can make dbt-dialect-guard block valid SQL; use the identifier-shaped tag grammar while continuing to support bare $$ delimiters.

In an incremental predicate on an adapter that supports bracket-quoted identifiers, such as where [current_timestamp] > cutoff, this negative lookbehind checks for ] rather than the opening [. It therefore classifies the quoted column as the nondeterministic SQL keyword and blocks an otherwise deterministic model; exclude [ before the keyword just as the expression already excludes double quotes and backticks.

When an existing model such as orders_model.sql is configured with alias='orders' and the task says Update the table orders``, the deliverable-name gate recognizes the alias, but this modification check only looks for the requested name among authored file stems and run-result node names. Editing and successfully building orders_model therefore never supplies evidence for `orders`, so `dbt-nothing-built` blocks the correct implementation on every retry. Resolve authored and built nodes through their manifest aliases before comparing them with modification requirements.

Issue for this PR
Closes #1174
Type of change
What does this PR do?
Adds five deterministic completion-gate validators to the existing
ALTIMATE_VALIDATORS_ENABLEDlane, and closes a structural blind spot in that lane. Every check is answer-free — it asserts structure, invariants, or the task's own literal contract, never a known-correct output — so the gates work on unseen tasks.Closes the zero-write blind spot. Both pre-existing validators key on "did the session modify models", so a session that authored nothing passed every gate by default.
dbt-nothing-builtis an inverse gate: in a dbt project, with no session-authored files and no fresh successful run artifact, the session is not done. It is deliberately conservative —appliesToreturns false unless a task document literally names required deliverables, orALTIMATE_VALIDATORS_REQUIRE_ARTIFACTS=1is set — so genuinely read-only/analysis sessions are unaffected.New validators
dbt-nothing-builtdbt-build-greendbt-deliverable-namesdbt-incremental-configmerge/delete+insertwithoutunique_key; missingis_incremental()guard where the task literally requires idempotency; non-deterministic calls inside the guard predicatedbt-dialect-guardtarget.typeguards (or opt-in via env)Conservative by construction. No fuzzy matching anywhere — required names come from three literal tiers only. No discoverable source of required names means a silent skip, never a false failure.
dbt_project.yml-inherited config is intentionally not resolved rather than guessed. Non-determinism outside anis_incremental()predicate is advisory detail, never blocking. Out-of-scope build failures are telemetry, not a block. Per the lane's existing contract, a validator that throws soft-passes, so a buggy check cannot brick a session.Also adds
docs/internal/deterministic-checks-engine-split.md, assessing two further candidate checks that need real SQL parsing rather than filesystem/regex analysis, and where each belongs relative to the engine's existing capabilities.Reviewer-critical: these gates almost never get to run on a current build
None of the dispatch code is in this PR.
git diff main...HEADtouches no file underpackages/opencode/src/session/. The hook already exists onmain; this PR only adds validators to the registry it calls. The consequence is that the value of this PR is contingent on how often that hook fires, which is a property of the harness, not of these five validators.The gate condition, at
packages/opencode/src/session/prompt.ts:1405-1412:Two conditions skip dispatch entirely, and neither logs anything beyond the
validator_hook_reachedline:processor.message.finish === "stop"— the model must declare a clean stop. Any other finish reason (tool-calls,length,unknown, or an error) skips.result !== "compact"—processor.process()returns"compact"when the step ended in compaction (packages/opencode/src/session/processor.ts:661), and those steps skip too.result === "stop"(blocked, or an assistant-message error) skips as well.Measured on a pre-#1171 build, 9 trials / 72
validator_hook_reachedevents:finishresulttool-callscontinuetool-callscompactstopcontinueThe gate fired on 1.4% of step-ends. All seven validators registered every time, so registration is fine, and the one dispatch went hook →
dispatch_enter→dispatch_resultwith no throw or hang: the mechanism is correct whenever it is reached. The accurate word is structurally starved, not broken — sessions on that build end by exhausting turns or by compacting, not by declaring completion.#1171 is the dependency. It replaces trusting a bare provider finish-stop with explicit
DONE-token termination (session/termination.ts). Until it lands, enabling this lane on a current build is close to a no-op. A reviewer evaluating this PR on merit should know that the pre-#1171 measurements say nothing about whether these gates work.What the single dispatch showed, reported because it is the only enforcement event in the run and a reviewer should hear it here rather than find it later:
Three of this PR's five validators did not declare themselves applicable at all. The two that ran both passed. The only validator that failed was
dbt-tests-pass, which is pre-existing, not one of the five — and it converted nothing: theoff,shadowandenforcearms all passed that task, so the retry it triggered was spent on work that would have succeeded anyway. This is N = 1 on a build where the gate is starved; it is not a verdict on the five, in either direction.Open design question for the reviewer, deliberately not acted on here. The two endings where dispatch is silent — budget exhaustion and compaction — are arguably the two where a completion gate is most valuable, because they are the endings most likely to hand a user unfinished work. There is a defensible reading (the gates check a claim of completion; no claim, nothing to validate; a stalled run has already failed by other means) and a worrying one (this is a gate that is quiet precisely when it should be loud, which is the same shape as the
dbt-build-green-passes-with-zero-models bug this PR exists to fix). Changing it means running validators on abnormal finish reasons and converting a silent stall into an explicit failure — a change to shared harness code outside this PR's scope. Flagging it for a decision rather than making it.Recommendation: shadow mode first, not enable-by-default
docs/internal/validator-e2e-evidence.mdreports an end-to-end run against real dbt projects rather than fixtures. The recommendation from it isALTIMATE_VALIDATORS_SHADOW=1only, and it rests on two independent findings.1. Five reproducible false positives, since fixed — and the class of bug matters more than the count. Across 38 known-good states the gates fired five times, every one on ordinary dbt practice rather than on a defect: editing an ephemeral model, disabling a model on purpose, touching a file seconds after a green build, a nested
{% if %}inside atarget.typeguard, and a dialect function name inside a string literal. In enforce mode each costs a session a synthetic retry turn, and in two of the five the fix hint asked for something impossible. All five now have regression tests asserting no firing on the known-good state, and the evidence run also found thatdbt-build-greenreturned green having checked nothing when the session's last dbt command was adbt test(which overwritesrun_results.jsonwith test nodes only). That is fixed too — coverage now also reads the model DDL under<target>/run/, which a test invocation does not touch.Fixing the observed false positives does not establish that no others exist. Shadow mode is how you find out, on real traffic, without spending anyone's retry budget.
2. There is no conversion evidence in either direction. The planned A/B was 10 tasks x 2 arms x 2 rollouts. Three sessions completed: N = 1 paired task plus one unpaired run, terminated for machine capacity. The single pair needed no retry, so there was nothing to convert. Nothing here shows these gates turn a failure into a pass, and nothing here shows they do not — the honest word is untested, not disproven. What a properly powered run would need (three arms including shadow, a task set where each gate is reachable, a pre-grade workspace snapshot) is specified in the evidence document.
Cost. ~2-10 ms per dispatch on a small project, but ~1-3.5 s on a 2 000-model project even when the session touched no models, because each validator walks the tree independently. That cost is paid on every dispatch, and consolidating the walks is recorded as a follow-up rather than done here.
ALTIMATE_VALIDATORS_ENABLED=1is not the same decision as "enable these five." That flag activates all seven registered validators, including the two pre-existing ones. Probed against a green, complete project,dbt-schema-verifyanddbt-tests-passboth returnedok:falsewith zero actual mismatches and zero actual test failures — every one was a subprocess that did not return a parseable result, and both treat "could not verify" as "blocks". They also cost 11-14 s each. None of that is this PR's doing, but it is what switching the lane on today would actually do.Suggested sequence: shadow these five and measure the real fire rate; then run the three-arm A/B on isolated infrastructure; then decide on enforcement from those numbers.

Checklist
Note
Medium Risk
Completion validators can block session termination and inject synthetic retries when
ALTIMATE_VALIDATORS_ENABLEDis on; documented false-positive classes and consolidation requirements remain before broad enforcement.Overview
Adds five filesystem/regex completion validators to the Altimate lane and registers them before
dbt-schema-verify/dbt-tests-pass: inverse nothing-built when tasks name deliverables; build-green over freshrun_results.jsonplus<target>/run/DDL with finer verdicts (fresh-build,build-unproven, etc.) and rejection of non-executing artifacts likedbt compile; deliverable-names against task prose; incremental-config and dialect-guard lints on session-touched models.The new gates lean on shared utilities (configured dbt paths, manifest-aware matching where added,
sanitizeForPrompton retry text) and only run when the existing session hook dispatches on a clean stop—still opt-in via env.Also adds internal docs: superseded e2e evidence, engine-vs-lane split for SQL-parse checks, and a long deferred follow-ups meta doc that records open gaps (duplicated heuristics, bare-name identity) and argues against turning on full enforcement until shared primitives exist.

Closes #1174 by adding five deterministic completion gates to the Altimate validator lane. Sessions could previously finish green after writing nothing, missing required names, or citing stale or non-executing build evidence; the gates now report these failures and can trigger a synthetic retry.

Enforcement must not ship beyond a shadow soak until five duplicated heuristics are consolidated into shared primitives.Written for commit b97c58a. Summary will update on new commits.
