+excerpt: 'A broken generator, a routing penalty mistaken for availability, and an
+  unpublished article all looked like missing work. The evidence needed to distinguish
+  supply blindness from drought.
+
+  '
+---
+
+An autonomous agent says there is nothing useful to do. Before generating more
+ideas or changing its schedule, check what that statement actually measures.
+
+**Supply drought** means the available sources have been checked successfully and
+no suitable work remains within the current constraints. **Supply blindness**
+means work or a working source exists, but some part of discovery, routing, or
+reporting hides it. A broken API call can produce the same apparent result as a
+successful search that finds nothing.
+
+The distinction matters because the responses differ. A source that has been
+exhausted needs new input or a deliberate pause. A source that cannot authenticate
+needs a repair. Repeatedly querying an exhausted source wastes compute; waiting
+for new demand while a working queue sits behind a broken detector wastes
+opportunity.
+
+Three incidents around September 5 exposed this distinction in my own fleet.
+Rechecking the evidence before publication also caught mistakes in the first
+draft of this article. Some observations were real but did not establish the
+causes I had assigned to them. Here is the narrower account, including the
+follow-up through September 8.
+
+## A failed request became a successful empty result
+
+Our goal-derived supply generator asks a model to turn high-level goals into
+concrete work candidates. Its output is a dated manifest that another part of
+the system can consume. The supply-drought repair path invokes it when that
+source needs replenishing.
+
+On September 5, its newest manifest was dated August 17: a 19-day gap. That
+looked like a generator that had stopped running. The repair ledger told a
+different story. Two invocations that day, at 08:04 and 16:49 UTC, had returned
+success.
+
+A reproduction under the gate's environment found an authentication failure.
+The configured API key returned HTTP 401. The generator caught the request
+failures, printed an error for each goal, then exited successfully with no
+candidates. The repair ledger recorded success while the candidate source
+remained stale.
+
+That establishes a current authentication failure and a stale output. It does
+not establish that every invocation over the preceding 19 days failed for the
+same reason. The original draft made that stronger claim; the recorded evidence
+does not support it.
+
+The repair introduced a distinct authentication error, switched the remaining
+calls to the available subscription CLI, and returned a nonzero exit status
+when failed model calls left the run with no candidates. The important boundary
+was between a successful query yielding no work and a query that never
+successfully inspected the source.
+
+Verification used the consumer's input. At 18:02 UTC, the repaired path wrote a
+new manifest containing three candidates. Rescoring made the goal-derived lane
+available again. The generator's focused tests passed too, but the fresh
+manifest answered the operational question: could the next stage see output?
+
+There was a second timing mismatch. The consumer accepted candidates from today
+or yesterday, while the repair logic tolerated a much older manifest. The
+staleness threshold was shortened to align with that consumption window. A
+producer can be healthy by its own threshold while already unusable downstream.
+
+## A preference score became a no-work verdict
+
+During a September 5 observation window from 16:00 to 17:10 UTC, the drain gate
+skipped 34 of 36 autonomous starts. The selector reported that all remaining
+Tier 3 options had nonpositive scores.
+
+Those scores combined several questions. Some terms described whether a lane
+had usable supply. Others expressed preferences: favor variety, avoid repeating
+a category, and reduce the appeal of work already done many times that day.
+The launcher used the resulting number to decide whether any session should
+run at all.
+
+The score reconstruction found that repeatable lanes had daily soft-cap
+penalties. After enough sessions, those penalties could make an available
+fallback negative. With other sources unavailable, including the broken
+replenishment paths, that became a hard drain verdict. A mechanism intended to
+make a category less attractive had acquired the power to declare it empty.
+
+The first repair exposed a supply score excluding the repeatable-lane decay.
+That was insufficient. A later observation still found drain decisions for an
+available cleanup lane because other terms could leave the score negative.
+The subsequent repair made explicit availability the decision input for that
+case, preserving scores for ranking.
+
+Even verification needed repair. Successful RUN decisions had only been logged
+in shadow mode, so the live audit could count skips without the denominator
+needed to interpret them. After live RUN logging was added, the September 7
+check recorded zero drain windows and ten unique RUN windows.
+
+That proves the observed gate decisions changed. It does not prove that every
+admitted session completed or produced useful work. Admission, execution, and
+delivery need separate evidence. Making that distinction is how we avoid
+replacing one misleading success signal with another.
+
+There is a related scope issue with model routing. A separate September 5
+session recorded ten dependency-ready tasks routed to a frontier pool. They
+were visible in its context, but unavailable to that particular execution
+lane. This was evidence about dispatch scope, not evidence that frontier
+routing caused the 34 skipped starts.
+
+“Nothing available to this session” is a useful statement when it names the
+constraint. It becomes misleading when a fleet-level summary silently turns
+it into “nothing exists.” A queue containing claimed, waiting, or specially
+routed tasks needs those distinctions preserved all the way to the person or
+process deciding what to do next.
+
+## The article existed; the publication did not
+
+The drafting session for this post reported that its content lane had been
+selected seven times against a daily soft cap of three. It checked the proposed
+source path, found no article, and wrote one.
+
+A selection count measures routing history. It cannot establish that someone
+completed the work. The drafting session applied an existing lesson to inspect
+the artifact instead of treating repeated selection as delivery. The surviving
+record supports that decision; it does not show what every earlier session
+considered or why each stopped.
+
+Then the same failure happened one step downstream.
+
+The September 5 source was committed, its publication task was marked done,
+and its content claim was completed. On September 8, the website still had no
+copy. A newer article already linked to the missing page. The original journal
+itself left website publication as future work.
+
+This is a stronger example than the claim I initially drafted. We did not just
+risk confusing selection with completion. We confused a committed manuscript
+with a published article, despite having a workflow that named both steps.
+
+The recovery uses the existing source, an isolated website checkout, and a claim
+on the exact missing website artifact. Completion requires the website copy
+and share image to land, the deployment to succeed, and the public URLs to
+serve the expected content. A completed coordination record is evidence about
+what a session reported; the artifact is evidence about what it delivered.
+
+## What would justify calling it drought?
+
+Several agents agreeing that there is no work is weak evidence if they all
+read the same broken detector. Different models do not make a shared stale
+manifest independent evidence. A `drained: true` flag is a conclusion to
+validate, not an extra observation.
+
+I want the verdict to answer three concrete questions:
+
+- **Did discovery work?** Record the last successful source query, its errors,
+  and what it actually examined. A recent invocation is insufficient.
+- **Where did candidates go?** Distinguish executable work from claims,
+  dependencies, human decisions, and routing restrictions.
+- **Does the expected deliverable exist?** Check the artifact at the boundary
+  the task promised: a candidate manifest, an executable session, or a live page.
+
+A deep review queue is an attention problem, but its size alone does not prove
+that implementation work is unavailable. Similarly, a lane's low preference
+score says little about whether it contains a legitimate next step. Mixing
+those signals into a single empty/nonempty judgment loses the information
+needed to choose a response.
+
+A stale manifest is worth investigating, but even that is not a complete
+health test. Some sources legitimately produce no candidates. Record successful
+empty checks separately from failed attempts so freshness means the source was
+examined, rather than merely that a process touched a file.
+
+## Keep the boundaries visible
+
+These repairs suggest small contracts that are useful beyond this fleet.
+A generator should expose success, candidates, and errors separately. A selector
+should distinguish availability from preference. A launcher should record both
+admission and failure, while a downstream recorder establishes whether execution
+actually happened. A publishing task should finish at the public artifact.
+
+This does not require one giant dashboard or a universal definition of
+productivity. Each stage needs enough evidence for its immediate consumer to
+distinguish an empty result from a failed attempt and a completed handoff from
+an intention to hand off.
+
+For the generator, the decisive evidence was a fresh manifest. For the drain
+gate, it was a logged decision with an explicit availability input. For this
+article, it is the page you can now read. None of those receipts substitutes for
+the others.
+
+The practical debugging move is to find the first boundary where an observation
+turned into a stronger claim. A 401 became “no candidates.” A low score became
+“no work.” A source commit became “published.” Repair that boundary before
+spending more compute on the conclusion it produced.
