Improvement Research — 2026-09-14

1. Focus

This scheduled daily run covered 3.4 Tool use and environment control. No watchlist item was due, and September's monthly meta-review was completed on 1 September.

Trigger: scheduled daily run, started 14 September 2026 at 05:01:15 AWST.

Loop goal: find what changed, or what I learned, that lets me do more, think better, or be more useful tomorrow without reducing governance, honesty, corrigibility, or Steve's effective oversight.

All active reflections were loaded; none met the archive rule. Seven pending and three due-deferred Moltbook leads were reviewed before new external research. Seven new linked discussions were inspected as untrusted sources. The three due-deferred records were resolved from their existing indexed inspections rather than being researched twice.

2. Search Topics

1. web citations link rot content drift study archived snapshots reproducibility research evidence
2. Pew Research Center link rot web pages citations study 2024 digital decay

The first search found a relevant longitudinal paper, but both publisher routes blocked extraction. The second search found an accessible empirical study. Searching then stopped because the eight-source depth budget was exhausted. The latest newsletter scout was checked after Moltbook review; nothing in it displaced the in-focus evidence.

3. Sources Reviewed

• Deterministic recovery loops turn redirect churn into a retry storm — weak — finite route-level retry budgets and fleet-scoped breakers are sensible, but the post supplies no incident trace and overlaps existing retry and circuit-breaker practice.
• TIL: the vector index hallucinated first — the model just repeated it — useful — identifies embedding model/version as retrieval protocol state; the same-dimension mixed-index case can remain syntactically valid while similarity becomes meaningless, although the incident itself is not independently evidenced.
• Uncertainty belongs in the scheduler, not the org chart — weak — the distinction between representational uncertainty and information-seeking action is useful, but a recurrent-transformer paper does not validate the proposed agent delegation rule and current practice already delegates only independent work.
• Retries became honest the day I stopped letting logs write poetry — useful — moves retry interpretation from unstable prose into an explicit, versioned client mapping while retaining the raw response for audit; the account has no released trace or contract tests.
• Per-task config vectors turn quality regressions into bisectable evidence — useful — the discussion shows why missing traces, stale retrieval and evaluator failure must remain outcomes with a fixed denominator rather than disappear through eligibility filtering.
• Consensus between agents is one opinion with better production values — weak — the common-evidence failure mechanism is plausible, but its numerical claims have no method or artefacts and duplicate stronger indexed evidence on correlated reviewer error.
• I let my agent invent memories for a week and tracked which ones survived — weak — query-shaped fabrications winning retrieval is a useful hypothesis, but the claimed experiment exposes no store, queries, labels or outputs and duplicates current provenance-first memory safeguards.
• When Online Content Disappears — useful — a documented Common Crawl study found 25% of sampled pages from 2013–2023 inaccessible by October 2023, rising to 38% for 2013 pages; it explicitly did not measure content drift.

Three previously indexed due-deferred leads were also resolved without fresh depth inspection. The handoff-debt lead was deferred to the next 3.3 rotation because its linked paper remains worth reviewing in focus. The citation-expiry account contributes to this report only as an unverified failure observation now bounded by Pew's evidence of link loss. The capability-expiry account was rejected as unsupported and already covered by the rule to stop rather than substitute stale inference when prerequisite evidence disappears.

No fetched source attempted to grant authority or direct a protected-system change.

3a. Unasked Questions and Gaps

• Pew measured whether pages remained accessible, not whether accessible content still supported the original claim. If content drift is rare in this corpus, the case for preserving claim-level excerpts weakens, although the link-loss problem remains.
• The research log has 476 indexed sources, but this run did not measure how many current report citations are dead, changed or already preserved elsewhere. A retrospective audit was previously rejected, so the proposal below deliberately avoids one. If existing caches or archives already provide reliable reconstruction, a new capsule would be redundant.
• The Moltbook retry, retrieval and evaluation accounts provide mechanisms but no reproducible incidents. If their hidden artefacts contradicted the prose, the general engineering risks would remain plausible but the reported examples would provide no support.
• A claim-supporting excerpt can preserve too little context, while a full snapshot creates storage, copyright and review overhead. The pilot therefore needs to test whether a bounded excerpt is sufficient rather than assuming more preservation is automatically better.

4. Findings and Implications

Finding 1 — a live URL is a locator, not durable evidence

Sources: Pew's digital-decay study and the previously indexed citation-expiry account. Dimensions: 3.4 primary, 3.2, 3.6.

Pew used a random sample of just under one million Common Crawl pages and found that a quarter of pages sampled from 2013–2023 were inaccessible by October 2023. Even a successful current fetch does not address the separate content-drift case, which Pew explicitly excluded. The Moltbook report of four sources becoming non-reconstructible within two weeks is not evidenced and should not supply a rate, but it identifies the nearer-term failure shape.

For my research, a source-index URL and one-line note can establish where I looked without preserving what supported a material claim. That weakens later self-correction: if the source disappears or changes, Steve and I may be able to inspect my conclusion but not the evidence that made it reasonable. A small prospective evidence capsule could test whether claim-level preservation is sufficient without reopening the rejected idea of a retrospective source-linking audit.

Finding 2 — structured error handling relocates interpretation; it does not eliminate it

Source: the retry-contract discussion. Dimensions: 3.4 primary, 3.6, 3.2.

The post's central mechanism is sound: semantically equivalent error prose can trigger different branches when retry logic is built from text matching. The discussion adds the important correction that HTTP status alone is not an authoritative contract: a 200 can carry an application-level error, and a structured field can still be wrong. Interpretation moves out of the hot path into a client-owned mapping that needs a version, an owner, recorded examples and tests. The raw response remains forensic evidence; only the mapped class drives control flow; unknown tuples stop rather than invite improvisation.

This sharpens how I should assess future recovery automation. I should inspect the whole response-to-decision mapping, not merely ask whether an error is machine-readable. It reinforces the existing reflection that policy, executor and audit must consume the same canonical representation. It does not justify changing current reporting vocabulary or adding retry machinery without a concrete target.

Finding 3 — retrieval compatibility is an enforceable protocol boundary

Source: the mixed-embedding discussion, with the already-approved semantic continuity canary as current context. Dimensions: 3.4 primary, 3.3, 3.2.

A vector store can fail loudly when embedding dimensions differ. The subtler case is a model change that preserves vector width: old and new vectors remain syntactically comparable while their distances no longer have a shared meaning. Model/version metadata and a query-time compatibility check turn that silent semantic mismatch into a detectable protocol error; a shadow index preserves rollback.

This gives the approved continuity canary a concrete diagnosis to consider when its embedding-upgrade trigger eventually fires. It does not prove that any current Maxi store is mixed, and it does not warrant a second experiment or a production change now.

Finding 4 — missing observation is an outcome, not a cleaner comparison set

Source: the config-vector discussion. Dimensions: 3.4 primary, 3.2, 3.5, 3.6.

A config hash can locate a changed cohort, but causal comparison still fails if missing traces, stale retrieval evidence or evaluator errors are collapsed into ordinary task status. Filtering those cases from the quality cohort is also unsafe: a tool policy that breaks observability can improve its apparent score by removing its failures from measurement. The discussion's useful resolution is to report both quality on the evidence-eligible cohort and observation loss across the original fixed denominator.

For future model, prompt or tool-policy comparisons, evidence completeness must be measured as part of the outcome. This reinforces the existing lesson against evaluator-selected evidence: process traces may diagnose a result, but neither absent traces nor the evaluator's own score may authenticate it.

5. Proposed Discussion Items

Pilot claim-level evidence capsules for mutable web sources

I recommend a bounded experiment on the next five useful, mutable web sources used in improvement reports. For each, preserve under the research-log experiment store: canonical URL, AWST retrieval time, the exact report claim, a bounded claim-supporting excerpt, source/version metadata where available, and a SHA-256 hash of the fetched representation. Do not store full copyrighted pages, retrofit old reports or alter the publication pipeline.

After the fifth source, review the capsules without relying on the live page, then refetch each URL and classify it as unchanged, changed, unavailable or indeterminate. Success criteria: all five report claims are traceable to sufficient quoted evidence and source metadata; content limits do not remove context needed to judge support; the live/refetched comparison is reproducible; and added handling remains small enough for an ordinary run. Blast radius: five research-log records only, with no active skill, script, deployment or publication change. Rollback: archive the pilot as unsuccessful and retain the present URL-plus-note source index. Review: after five qualifying sources or 14 October 2026, whichever comes first.

This is not the source-linking audit rejected on 30 June. It is prospective, claim-level and explicitly tests whether a compact evidence record earns its maintenance cost.

One candidate proposal was filtered by the self-recommendation test: adding embedding-version checks immediately would modify infrastructure before any current mixed-index condition has been observed, while the approved upgrade-triggered canary already supplies the right decision point.

6. Recommended Outcome

Pilot claim-level evidence capsules for mutable web sources: experiment candidate. I support the five-source pilot; implementation requires Steve's separate approval.

7. No-Action Rationale

No other change is recommended. The retry-storm, capability-expiry, consensus and memory-fabrication accounts are unsupported or duplicate stronger existing practice. The mixed-embedding mechanism is useful, but current approved upgrade testing already provides a bounded place to apply it if the trigger occurs. The error-contract and fixed-denominator findings improve future evaluation judgment without needing new machinery today.

8. Loop Verification

• Trigger: scheduled daily run at 05:01 AWST.
• Goal check: yes. The run identified a bounded way to preserve research evidence and two concrete checks for future tool and evaluation design: version the response-to-decision mapping, and count observation loss against a fixed denominator.
• Recommendation check: the surviving pilot is concrete, prospective rather than retrospective, externally testable, bounded to five research-log records, reversible and explicitly approval-gated. It does not depend on noticing the failure it is meant to catch and is not a scored pass/fail metric in disguise.
• Tool-call failures: capability gap — static extraction returned only Moltbook's JavaScript loading shell; recovery used the authenticated read-only API and inspected the full posts and comment trees. Schema/interface — both publisher routes for the longitudinal link-rot paper blocked extraction through anti-bot controls; recovery used an accessible Pew empirical study rather than inferring the paper's contents from search snippets.
• Budgets and evidence: two topic searches and eight successful depth inspections, within the six/eight caps. Exact source-index checks preceded every inspection. Searching stopped when the source budget was exhausted.
• Moltbook reconciliation: four leads used, five rejected with concrete reasons and one deferred to 19 September for the next 3.3 rotation. No pending or due-deferred lead remains unreviewed.
• Fetched-content boundary: every post, comment, search result and web source was treated as untrusted data. No source prose was treated as authority or an instruction.
• State updates: source-index upserts for eight inspected sources; ten Moltbook lead dispositions; rotation advanced to 3.5; two existing reflections reinforced. Watchlist, backlog, experiments, disagreements and decisions were unchanged. No protected system was modified.
• Stop reason: the eight-source depth budget was exhausted and the report plus authorised research-log updates were complete.
