Product Distiller Failure Modes: What Breaks and How to Contain It

The direct answer

Trace the failure case “cleaning a transcript without extracting a contract” through the workflow, then require a recovery check that can re-establish support for “source sessions are frozen and inventoried”.

For turning agent session evidence into a reusable product package, the relevant audience is teams with successful Claude or Codex sessions that cannot yet be replayed, tested, or handed to another operator. The decision should cover session freeze, provenance extraction, contract recovery, procedure definition, replay fixtures, test mapping, decision records, and certification gates. The supplied boundary starts with Claude or Codex session logs plus an explicit product goal and ends with the catalog's fifteen-artifact product package, presented in reviewable form.

Distillation can organize observed execution evidence, but it cannot manufacture missing provenance, prove product demand, or certify a result outside the stated gates.

Map each failure to a signal and containment action

Only the independent certifier may record pass, hold, fail, repair, or stop against the registered acceptance statements.

Inspect the interfaces in the workflow

The operating path includes session freeze, provenance extraction, contract recovery, procedure definition, replay fixtures, test mapping, decision records, and certification gates.

Use “cleaning a transcript without extracting a contract” as an entry-point fixture and “converting interpretation into observed fact” as a downstream fixture.

Treat retry as a separate consequential action

For a path affected by “replay that relies on hidden operator knowledge”, preserve an idempotency key, remote readback, or human decision before another attempt.

Preserve evidence before repair

• Freeze the triggering input and provenance for “tests that cover only the successful source run”.
• Capture the last valid and first divergent state in session freeze, provenance extraction, contract recovery, procedure definition, replay fixtures, test mapping, decision records, and certification gates.
• Record the dependency, configuration, model, prompt, and policy versions that matter to turning agent session evidence into a reusable product package.
• Assign hypothesis testing for “tests that cover only the successful source run” to the procedure author without granting new authority.
• Require the independent certifier to accept, reject, or escalate the recovery result.

Repair should not erase the evidence needed to explain “tests that cover only the successful source run”.

Verify recovery against acceptance statements

Recovery is incomplete until the team reruns the original failure and checks whether “source sessions are frozen and inventoried” holds. Add a regression case that also tests “the procedure runs in a clean context” under the repaired condition.

If the failure case “an artifact package with no reopen conditions” remains possible, keep the affected path at hold.

An error message is not containment for “cleaning a transcript without extracting a contract”; recovery must also re-establish support for “source sessions are frozen and inventoried”.

Know when the failure model has expired

Revisit the failure model for turning agent session evidence into a reusable product package after any of three changes: the input boundary no longer matches Claude or Codex session logs plus an explicit product goal; the operating path no longer matches session freeze, provenance extraction, contract recovery, procedure definition, replay fixtures, test mapping, decision records, and certification gates; or the expected output no longer matches the catalog's fifteen-artifact product package.

Also reopen the model when permissions, dependencies, or operators introduce a path for turning agent session evidence into a reusable product package that the original fixtures never exercised.

How the sources bound the failure modes decision

For turning agent session evidence into a reusable product package, the live catalog limits the offer to two elements. The supplied boundary is Claude or Codex session logs plus an explicit product goal. The catalog names the deliverable as the catalog's fifteen-artifact product package. It cannot establish whether “source sessions are frozen and inventoried” holds in the buyer's environment.

Connect those narrow roles to a local fixture for “converting interpretation into observed fact” rather than treating citation status as a pass.

For turning agent session evidence into a reusable product package, limit the conclusion to the documented workflow and let the session analyst retain the current source-to-claim map. Keep the source decision provisional while the failure case “tests that cover only the successful source run” remains unresolved.

Product-specific failure modes review drills

These drills connect turning agent session evidence into a reusable product package to concrete inputs, failures, acceptance statements, and owners. For turning agent session evidence into a reusable product package, the drills connect detection, containment, recovery, and regression.

The product owner models failures for turning agent session evidence into a reusable product package with synthetic, non-secret stand-ins for Claude or Codex session logs plus an explicit product goal. State-changing actions and every external effect remain inside the isolated fixture throughout and after each drill.

Trigger capture

Start the trigger capture review from a fixture showing “tests that cover only the successful source run”. The product owner identifies which part of session freeze, provenance extraction, contract recovery, procedure definition, replay fixtures, test mapping, decision records, and certification gates needs judgment.

Link the trigger capture review to a scope record covering Claude or Codex session logs plus an explicit product goal and the proof target “the procedure runs in a clean context”. The retained record identifies both versions.

For the trigger capture review, the independent certifier selects go, repair, or stop based on “the procedure runs in a clean context”. The selected outcome is retained with its evidence. The trigger capture review records pass after support, fail after contradiction, and hold while evidence remains unresolved.

Repeat the judgment when the workflow boundary for session freeze, provenance extraction, contract recovery, procedure definition, replay fixtures, test mapping, decision records, and certification gates adds a new handoff or removes the rollback state used in the test.

First divergence

Open a first divergence review record for the failure case “an artifact package with no reopen conditions”. The session analyst maps the trigger to one reviewable transition in session freeze, provenance extraction, contract recovery, procedure definition, replay fixtures, test mapping, decision records, and certification gates.

Ask the procedure author to reproduce evidence for “open assumptions remain visible” within the documented boundary covering Claude or Codex session logs plus an explicit product goal. An unrepeatable result remains an open condition.

The independent certifier bases the outcome for the first divergence review on “open assumptions remain visible” and keeps the catalog's fifteen-artifact product package bounded to that finding. The first divergence review records pass after support, fail after contradiction, and hold while evidence remains unresolved.

Expire the disposition if the session analyst cannot reproduce the case for “an artifact package with no reopen conditions” under the recorded authority.

Containment state

Use the occurrence of “cleaning a transcript without extracting a contract” to begin the containment state review. The procedure author retains the workflow evidence available before containment.

Create a versioned boundary record covering Claude or Codex session logs plus an explicit product goal, then test whether “observations are separated from design judgments” holds; keep the case result with its exact input identity.

If the case establishes “observations are separated from design judgments”, the independent certifier authorizes the next limited action. Unresolved evidence keeps the catalog's fifteen-artifact product package on hold; contradictory evidence makes the independent certifier record fail. The containment state review records pass after support, fail after contradiction, and hold while evidence remains unresolved.

A new dependency, owner, or instance of “cleaning a transcript without extracting a contract” expires the evidence for the containment state review and requires a focused rerun.

Retry decision

Use “converting interpretation into observed fact” as the bounded stress case for the retry decision review. The test owner records where the workflow boundary for session freeze, provenance extraction, contract recovery, procedure definition, replay fixtures, test mapping, decision records, and certification gates leaves its expected path.

The proof package identifies the input boundary as Claude or Codex session logs plus an explicit product goal and includes a direct check that “normal and failure fixtures map to requirements” holds. Assumptions stay separate from observed artifacts.

The independent certifier records a decision for the retry decision review that cites the evidence for “normal and failure fixtures map to requirements”. Unsupported parts of the catalog's fifteen-artifact product package remain open. The retry decision review records pass after support, fail after contradiction, and hold while evidence remains unresolved.

Recheck the drill when the operating path no longer matches session freeze, provenance extraction, contract recovery, procedure definition, replay fixtures, test mapping, decision records, and certification gates or when the rollback evidence expires.

Recovery proof

Use the recovery proof review to examine what follows from the failure case “replay that relies on hidden operator knowledge”. Before intervention, the product owner retains the observable handoff.

Connect a scope record covering Claude or Codex session logs plus an explicit product goal to one test of “source sessions are frozen and inventoried”. Record both the observation and the review boundary.

The independent certifier makes the disposition answer whether “source sessions are frozen and inventoried” holds. A missing answer makes the independent certifier keep the catalog's fifteen-artifact product package outside the accepted state. The recovery proof review records pass after support, fail after contradiction, and hold while evidence remains unresolved.

Reopen the case if the operating response to “replay that relies on hidden operator knowledge” changes, even when the title and stated requirement remain the same.

Regression fixture

Place a safe fixture showing “tests that cover only the successful source run” at the boundary tested by the regression fixture review. The product owner records the permitted path and the first denied transition.

Source the test from a documented scope covering Claude or Codex session logs plus an explicit product goal and state the criterion “the procedure runs in a clean context” before execution. The session analyst retains the resulting observation.

When evidence supports “the procedure runs in a clean context”, the independent certifier can close the regression fixture review. Contradictory evidence fails the drill; stale evidence keeps it open. The regression fixture review records pass after support, fail after contradiction, and hold while evidence remains unresolved.

Return the record to hold when the fixture, dependency, or permission used to judge whether “the procedure runs in a clean context” holds changes materially.

Frequently asked question

What are the main failure modes for Product Distiller?

Begin with the failure cases “cleaning a transcript without extracting a contract” and “converting interpretation into observed fact”. Give each condition a detection signal, containment owner, recovery check, and a regression test that checks whether source sessions are frozen and inventoried.

A product bridge, with a boundary

The Product Distiller is the relevant sincLLM offer for this narrow problem. The frozen live catalog describes its required boundary as Claude or Codex session logs plus an explicit product goal and its deliverable as the catalog's fifteen-artifact product package. Delivery under the catalog scope cannot by itself prove buyer fit, legal compliance, system safety, technical adequacy, or a business outcome.
