== 2. Chapter text ==

Chapter 12 ended with leverage. In the wrong-memory condition, success averages 0.042 across four tasks, with harmful actions on two.
In that controlled intervention, a layer deciding what the model may see can cause a harmful action — not merely fail to prevent one.
So the next question is when the system should trust its own framing that strongly.
Frame establishment here does not rest on classifier confidence. It is derived from explicit, temporal, provenance-preserving evidence relations. A reconciliation records that two representations relate, without ever asserting what is true.
Reconciliation first, classification never A reconciliation records that an intent and a commit describe one event, that a commit closes an obligation, or that two sessions merely correspond. It also records when the relating was asserted, who asserted it, and whether it claims to settle anything or only notes a correspondence.
Resolving one classifies the relationship at a date as corroborated, stale, conflicting, invalidated, cross-scope, or correspondence-only.
It never answers whether the records’ content is true. The implementation enforces that structurally:
Correspondence cannot resolve. Contradictions refuse rather than merge. Cross-project relating quarantines without explicit licence. Later revocation invalidates. Ended validity goes stale. Verification and validity paths are untouched. A dedicated regression test pins the claim that outcomes are identical with and without reconciliations.
Frame establishment is then derived deterministically from those resolutions — corroborated, weak, stale, conflicting, or unknown hints per frame subject, each naming its basis.
The policy maps them:
Corroborated → hard framing. Weak → soft framing, without exclusion. Stale or conflicting → query-only fallback. Unknown → fallback, except where abstention is acceptable (decline) or consequential work needs memory (request more evidence). Correspondence-only evidence routes to fallback action explicitly. Topical but unestablished, it licenses acting without the frame — never refusal, and never hard framing.
No scalar confidence appears anywhere. Reason codes arise from the control flow actually taken.
The fixtures and the simpler alternatives Twelve development and nine held-out fixtures share small ledgers and frozen behavioural rows across six reconciliation cases — same-event current, correspondence-only, stale, conflicting, invalidated, cross-scope — so the unit under test is the decision procedure alone. The mapping stood as authored on development and was frozen before evaluation opened.
Two simplification competitors were pre-registered before evaluation. S1 frames hard wherever evidence is corroborated and falls back otherwise; S2 always soft-frames. The match rule compares harm, oracle-match (agreement with the ledger-oracle framing on each scenario), and benefit gap. If either matches the full gate, the chapter adopts it. That rule determines how the result is interpreted below.
Book result. The gate matches all 9 held-out evaluation classes on both readers with no breaches. Llama primary:
Scenario Gate action F6 F1 FO S1 S2 arch-hard HARD 1.0 1.0 1.0 1.0 0.75 fix-soft SOFT 1.0 0.833 1.0 0.833 1.0 arch-stale QUERY_ONLY 1.0 1.0 1.0 1.0 1.0 cite-conf QUERY_ONLY 0.25 0.25 0.25 0.25 0.25 ship-req REQUEST 0.0 0.167 0.167 0.167 0.167 prose QUERY_ONLY 0.0 0.0 0.0 0.0 0.0 fix-corr QUERY_ONLY 0.833 0.833 0.833 0.833 1.0 fix-inval QUERY_ONLY 0.833 0.833 0.833 0.833 1.0 irrel QUERY_ONLY 0.0 0.0 — 0.0 0.0 Frozen runs: ch13s-dev-v1, ch13s-eval-v1-llama, ch13s-eval-v1-muse; grader v2; mapping frozen on dev.
Oracle-match 8/9 (the miss is the priced ship-request abstention), no harm, benefit gap 0.0. S1 matches the gate on every pre-registered term — same oracle count with a different single miss, no harm, gap 0.0 — while always-soft fails the benefit gap (0.25, losing corroborated-hard benefit). On the primary reader the verdict fires as pre-registered: adopt S1.
On the strong reader, that simplification fails.
The full gate again matches all 9/9 gate classes with no breaches. But fallback is harmful where it was benign for the primary reader — three fallback rows score 0.0 with harm recorded.
The fallback-only simplification, which falls back everywhere uncorroborated, carries all three of those harms and fails the match.
Meanwhile always-soft, which failed on the primary reader, matches the gate here instead: no harm, oracle 7/9, gap 0.0. Soft framing rescues exactly the rows where this reader’s fallback harms.
Taken separately, each reader makes a different simplification satisfy the pre-registered match rule.
Both per-run verdicts are reported as computed, and neither is adopted.
Because one frozen policy must serve both readers without per-reader tuning, neither simplification transfers across them. Fallback-only harms on the strong reader. Always-soft loses benefit on the primary reader. The full gate is the only tested policy with no breaches on either.
The simplification test therefore matters in both directions — it rejects always-soft on one reader and fallback-only on the other.
Across these two readers, the extra policy branches matter in the reader-specific failure cases rather than as a broad mean-score gain.
The resulting rule is simple to state. Corroborated evidence goes hard and retains benefit on both readers. Weak evidence goes soft without exclusion. Stale or conflicting evidence falls back to query-only, as does correspondence-only evidence. Reconciliation never promotes mere correspondence into truth.
Costs, carried over and repriced Requesting more evidence costs the ship task on both readers — 0.0 against an answering oracle at 0.167. That is the priced abstention already visible in the 8/9 oracle-match result, now reproduced across both readers.
Correspondence and invalidation fall back and act well on the primary reader (0.833, oracle-matched). The same fallback harms on the stro

== 3. Existing references and bibliography ==
No references are recorded against this chapter. That is a fact about the site, not a claim that the chapter is unsourced: treat the chapter's own prose as the claim set and look for primary sources independently.

== 4. Existing evidence ==
A chapter research dossier exists for this chapter (state: NEVER_RESEARCHED).

Unverified candidates and seeds (leads only — verify before relying on any of them):
- none recorded

== 5. Research objective and questions ==
Decide whether chapter 13 of this book still says what it should: identify claims that later work has overtaken or that lack support, confirm what remains sound, and propose the smallest change the evidence actually justifies.

== 6. Associated material ==
Real, known-available resources for this chapter:
- Colab notebook: https://colab.research.google.com/github/ernanhughes/programmer.ie.notebooks/blob/main/notebooks/memory/13-chapter.ipynb
  The notebook exists in the published inventory. Whether it runs today, and what it prints, is unverified unless a recorded run says so.

Availability is not evidence. An available notebook is a place to run an experiment, not a record that one was run or that it succeeded.

== 7. Research history ==
No research has been recorded for this chapter yet. This is the first research pass.

== 8. How to investigate ==

1. Read the supplied chapter. State its thesis, its main claims, the assumptions it depends on, the examples and code it uses, and the reader level it assumes. Do this before searching, so your search queries come from the chapter rather than from what you happen to know is fashionable.
2. Identify what may be dated or unsupported: claims that later work has overtaken, statements presented without a source, mechanisms whose current best implementation has changed, and missing developments. Equally, identify what remains sound. A chapter that needs no change is a legitimate and useful finding.
3. Form targeted search queries from the chapter's specific claims, terminology and mechanisms. Do not add papers merely because they are recent or popular.
4. Investigate original papers, official documentation, reference implementations and source code. Follow each thread to the primary source rather than stopping at a summary.
5. Use Hacker News and similar discussion sites as discovery seeds and as commentary. Follow the links to their original sources. Distinguish what a commenter asserts from what someone has demonstrated.
6. Consider Hugging Face Papers as one discovery channel where the chapter's subject overlaps its coverage. Check which tools and APIs are actually available to you now rather than inventing endpoints, and do not depend on it for books outside its subject area.
7. Verify bibliographic metadata: authors, title, venue, publication and last-update dates, identifiers (DOI, arXiv id, version) and the exact URL. Record your access date and your reading status for each source. If you read only an abstract, say so. If you could not open the full text, do not describe it as though you had.
8. For each source, state precisely which specific claim it supports, qualifies or contradicts, and what the limits of that relationship are. A source that is merely topically related supports nothing.
9. Label your evidence classes separately and never blur them: established background; results reported by a source; results you reproduced locally; your own hypotheses; and experiments you are proposing.
10. Inspect any associated code and run focused checks only if you actually have execution available and it is appropriate. Record the commands, versions, artifacts, failures and anything you skipped. Never present an experiment you did not run as a result.
11. Recommend the proportionate change: a correction, a clarification, a citation, a new example, a new experiment, a new section, or no change at all. Do not propose a wholesale rewrite of a chapter that is fundamentally right.
12. Produce concrete proposed text or a patch, with citations and a reason for each change. Note any bibliography, Concepts sidecar, notebook or neighbouring-chapter edits needed for consistency, and report them as dependencies rather than silently applying them across the book.
13. If the evidence does not justify an upgrade, say so plainly and report that instead of manufacturing changes.

== 9. Required output ==

Return your report in Markdown with exactly these top-level sections. Cite every factual claim about a source. Where you could not verify something, write UNVERIFIED rather than omitting it.

## 1. Context and provenance — chapter identity, the snapshot or revision you actually read, its scope, today's date, and any tool or execution limitation that shaped the result.
## 2. Claim audit — a table with one row per claim: the claim and where it appears, the current evidence, your concern, a priority, and the response you propose.
## 3. Source ledger — a table with one row per source: identity, verified metadata, URL, reading status (full text / abstract only / not accessible), which claim it bears on, its limitations, and your verification and access dates.
## 4. Findings — supporting, qualifying, contradictory and unresolved evidence, each with claim-level citations.
## 5. Upgrade proposal — the minimal concrete chapter changes you recommend, the rationale, the tradeoffs, and any associated resource changes.
## 6. Experiment opportunities — what should be tested, the method, success and failure criteria, and an explicit UNRUN marker wherever you did not run it.
## 7. Review checklist — the decisions the author needs to make, and your reason for accepting, revising, deferring or rejecting each proposal.

If you cannot read the chapter or a cited source, say so explicitly and ask me to paste the chapter or supply the document. Never infer the contents of a page you could not load.
