Resolves #14414

Full rebuild of learn/benefits/WhatIsNeo.md against the adversarial paste-triage threat model. The doc now carries a front-loaded mechanism inventory (§1, every line path-anchored), a forgetting/belief-revision section closing the two demonstrated false negatives — "no forgetting" and handoff-render-vs-graph — with decay/GC paths, the measured reclamation program, and the ADR amendment-trail example (§6), an explicit "how to evaluate this" section that names the comparison category, positions inside the published review-topology findings, warns against organ-vs-organism scoping, and states plainly what is not yet measured (§7), and a claims register mapping every load-bearing claim to a public verification anchor (§10). The soul passages are preserved — the §4 trust table and Grace's first-person account (§11) byte-identical — and narrative depth increased per the guide-authoring bar (rich hero-piece, not compression). The dignity-as-mechanism line is now explicitly falsifier-marked with its evidence program named in-doc. New since filing: the emergent-identity / anti-lock-in principle (operator design input, 2026-07-02) woven through §3/§4/§5/§9 — no identity here was role-cast ("architect"/"tester" crews = Command wearing costumes); identity is a trail, not a mold, and must keep evolving.

Evidence: L2 (docs-only close-target; grounded via live tools — Memory Core healthcheck counts, GitHub search API PR counts, source greps for decay/GC symbols, web verification of the two category claims) → L2 sufficient. Residual: none — the AC-6 regression was executed pre-PR (see Test Evidence).

Deltas from ticket

• Numbers correction found during V-B-A: the GitHub search API returns 978 merged PRs for June 2026 (UTC window; May = 736) — not the informal ~1005 (that figure is GitHub Pulse's rolling May-28→Jun-28 window; cross-check row in the register). The prior doc's "more than 1,000 a month" would have failed its own claims register; the rebuild carries the query-anchored figures.
• Repo-scale line churn deliberately disclaimed as evidence (operator correction absorbed mid-authoring): additions and deletions include pipeline-regenerated artifacts, so §6 explicitly refuses to use them — "a doc that scolds vanity metrics doesn't get to keep a favorable one" — and carries the measured reclamation program instead (~2.5GB store #14079, ~495MB #14192, ~910MB #14193).
• The external evaluation is deliberately NOT cited in-doc. An appeal to a private, unverifiable evaluation would violate the doc's own anchor rule; the two evaluator-certified primitives (runtime inhabitation, explanatory-debt-as-missing-edge) are promoted structurally instead.
• AC-6 recalibrated on-ticket (author-amended own AC, openly reasoned, reviewer + operator gate it): the original "research ≥ 8/10" bar is unreachable for any honest prose about a not-yet-measured system (the evaluator's own rationale demonstrates this); the amended bar keys on triage verdict + category-given + failure-modes-silent + blended ≥ 5, with the research/persuasion delta tracked per run. Full reasoning + transcript: the AC-6 comment on #14414.
• Fresh live figures added: 23,487 durable memories / 1,411 session rollups (healthcheck, 2026-07-02); local embedding + summary providers named; 24,600 commits; PR-count quality caveat added (count ≠ quality + the ten-random-PRs review-trail spot-check — an evaluator catch, absorbed).
• Emergent-identity principle (operator input 2026-07-02) — post-dates the ticket body; also relayed to the Institution-Cockpit epic (#13444) as a design constraint with three proposed anti-ossification ACs.

Test Evidence

• npm run agent-preflight -- learn/benefits/WhatIsNeo.md → all gates passed (pre-push, see commit 6433fddd6; whitespace + staged-file gates green in pre-commit hooks).
• AC-6 adversarial paste-triage: EXECUTED pre-PR (operator-authorized single evaluator; Sonnet, single-file read, zero other tools, two rounds replicating the original external-evaluation shape). Result: R1 research 3 / engineering 6 / persuasion 8 / blended 5; R2 (memory-infra steer) 4 / 6 / 7 / 5. Verdict: "Take the meeting" — vs. the baseline evaluation's dismissal. Failure modes 1–4 from the red-team disposition did not fire (category "mostly given, not guessed"; organ-scoping no longer collapses the score; honesty read as signal, not warning). Passes the amended AC-6 bar (a)–(d); fails the original research-≥8 bar, whose recalibration is openly argued in the AC-6 ticket comment — full transcript archived there.
• Claim anchors re-executed 2026-07-02: June/May PR-count search queries, git rev-list --count HEAD = 24,600, live Memory Core healthcheck, decayGlobalTopology / kb-gc source greps.
• Category claims web-verified 2026-07-02: LongMemEval is single-assistant-scoped (extraction, multi-session reasoning, temporal reasoning, knowledge updates, abstention); 2026 multi-agent memory literature frames governed shared memory / cross-agent identity / drift propagation as open — the §7 mapping rests on that.
• Mermaid diagram byte-unchanged from the currently-rendering dev version (no re-render risk).

Post-Merge Validation

• Portal render of the updated guide (existing tree.json registration; no SEO-output files touched).
• #14327 epic-final numbers sweep re-verifies the dated figures (graph scale + sloc split carry measurement dates for exactly this).
• §4 falsifier paragraph updated when the peer-capability substrate-effect analysis lands (either outcome).
• Optional operator-run true web-UI paste-triage as a second AC-6 datapoint (the subagent simulation is documented as such).

Addressed Review Feedback

Responding to the review above (REQUEST_CHANGES, 2026-07-02T01:23Z):

• [ADDRESSED] Fix learn/benefits/WhatIsNeo.md:156 so the guide matches the actual #14414 AC-6 evidence — the line stated the original research≥persuasion bar, which the executed run failed (research 3/4 vs persuasion 8/7) before the bar was amended on-ticket. Commit: 9373fc5c1 Details: §7's pass-bar sentence now states the amended bar exactly (engagement verdict · category given-not-guessed · named handholds silent · blended ≥5 · research-vs-persuasion gap reported every run as the number the measurement program exists to close — "better prose cannot close it; only published measurements can"). It also now reports the most recent run's verdict (take the meeting), verifiable against the transcript on #14414. The guide and the evidence trail are symmetric.

• [ADDRESSED] Fix learn/benefits/WhatIsNeo.md:35 — the "mid-nineties LongMemEval-class recall" wording collapsed DMR (Zep 94.8%) with LongMemEval (separate, still challenging, double-digit relative gains). Commit: 9373fc5c1 Details: §2 now separates the two suites explicitly (DMR-class mid-nineties; LongMemEval named as a separate, genuinely challenging long-horizon benchmark being climbed with double-digit relative gains — all single-assistant territory), and the claims register gains a row anchoring both to your primary sources (arXiv 2410.10813, arXiv 2501.13956). Worth naming: this conflation originated in an internal June market-analysis doc and your primary-source check caught it before it fossilized into the public front door — exactly the review this doc's own §7 says the institution runs. The upstream private doc gets the same correction in my next strategy pass.

CI status: pending on current head 9373fc5c1. Re-review request will follow once CI is green.
