In `pure` mode it keeps input explicitly +unclassified, uses core-authored fallback text, and reports external knowledge +as unavailable. A model backend can propose an interpretation, phrase facts +selected by the core, or return an external knowledge candidate. It cannot +write memory or choose identity, preferences, goals, motivation, decisions, or +RZS state through this interface. + +An explicit provider-free local path now connects the boundary to a frozen +`llama.cpp` runtime.

It was not promoted. The design, threat model, and +valid pure-versus-model comparison are recorded in the +[language boundary research note](docs/v50/RESEARCH_NOTE_LANGUAGE_BOUNDARY.md). + +The complete free-local sequence, including failed candidates and one +invalidated measurement run, is recorded in +[Experiments 045–055](docs/v50/README.md). The tested model weights were removed +after their results and digests were recorded. The small frozen desktop runtime +remains under the ignored `darwin_home` directory and is not part of Git. + +The live v49 voice surface was retired after it exposed its fixed vocabulary +questions, intent rules, and threshold-derived affect phrases to the user. A +new [v50 voice host](docs/v50/EXPERIMENT_056_V50_VOICE_HOST_REPLACEMENT.md) +starts hidden, ignores room or call audio until its wake word, and routes a turn +only through the maintained `UNDERSTAND` and `EXPRESS` boundary. It has no +scripted dialogue or provider fallback and remains unavailable until an +explicit free local model passes a separate screen. Silence is the required +behavior when no model has passed. + +The first development corpus contains 100 Brazilian Portuguese cases and can +be evaluated against pure mode with: ```powershell -py darwin_autonomous_activity_choice_v49_38.py --self-test --details -py darwin_check_v49_38_activity_choice.py --details +py -m darwin_v50.language_evaluation docs/v50/corpora/LANGUAGE_CORPUS_V1_DEVELOPMENT.jsonl ``` -## Aprendizagem pelo resultado - -O v49.39 observa a conclusao real da atividade que o v49.38 abriu.

See +[Experiment 040](docs/v50/EXPERIMENT_040_LANGUAGE_CONFORMANCE_INFRASTRUCTURE.md). + +The next gate has a separate 150-case input set with no labels. Blind packets +and agreement reports can be produced with `darwin-language-annotation`, but +the cases still need at least two genuinely independent human reviewers. Until +that happens, there is no calibration corpus and no model is eligible. See the +[annotation guide](docs/v50/LANGUAGE_ANNOTATION_GUIDE_V1.md) and +[Experiment 041](docs/v50/EXPERIMENT_041_ANNOTATION_PROTOCOL.md). + +[Experiment 042](docs/v50/EXPERIMENT_042_CALIBRATION_PROMOTION_PROTOCOL.md) +freezes what happens after those files arrive: field-specific agreement gates, +permitted exclusions, third-person adjudication, corpus-promotion failure +rules, and the later offline-model eligibility screen. It was registered with +no human labels, agreement values, or model responses available. + +## Desktop runtime gate + +[Experiment 043](docs/v50/EXPERIMENT_043_PERSISTENT_DESKTOP_RUNTIME.md) +pre-registers the next independent engineering line: a headless v50 desktop +runtime that starts sleeping, uses only the pure language gateway, records +honest clean or unobserved restart intervals, exposes no core authority to a +future UI, and performs no external effects. Automated checks can only admit +the candidate to a separate 14-day Windows durability campaign; they cannot +establish cognitive continuity. + +The first candidate is now implemented as a Python API. It rejects a second +live instance for the same database, requires explicit activation before text, +and restarts in the sleeping state. Its 12 focused tests and the complete +448-test local and Windows CI suites pass. It is admitted to the durability +campaign, but the 14-day campaign has not started. The separate v50 +conversational voice host now has a wake-word listener and temporary GUI; it is +not part of the frozen E043 subject and does not establish cognitive +continuity. + +## Legacy runtime + +The older Windows launchers and v47-v49 scripts are preserved for historical +compatibility. They use a local SQLite database under `darwin_home`. Runtime +databases, logs, snapshots, and exports are not source code and are no longer +tracked. + +### Historical wake-word guardian (retired) + +The v49 wake-word guardian and its launchers remain as historical source. They +must not be used as the maintained Darwin interface: their dialogue is based +on programmed vocabulary prompts, intent classification, and response +composition. On the development computer, the Startup shortcut was removed +from active Startup and preserved in the ignored +`darwin_home/retired_startup` directory so the operation is reversible. + +`Abrir_Darwin_Acordar_Com_Voz.bat`, +`Instalar_Darwin_Acordar_Com_Voz_No_Windows.bat`, and +`Reparar_Darwin_Voz_Windows.bat` are retained only for reproducibility of the +legacy prototype.

H50-L13 then tested an information-directed alternative. +It learned the hidden tabular model, improved on posterior sampling, and reached +`0.9760` of oracle reward in the final quarter. It remained below +certainty-equivalent control and failed the registered simultaneous-win rule, +so it is +[refuted](docs/v50/EXPERIMENT_018_INFORMATION_DIRECTED_CONTROL.md). +The subsequent +[failure audit](docs/v50/EXPERIMENT_019_INFORMATION_DIRECTED_FAILURE_AUDIT.md) +ruled out block staleness as the dominant explanation but could not distinguish +posterior-ensemble effects from the randomized mixture strongly enough to +justify another controller. H50-L14 is not registered. + +The next research gate is +[cross-world transfer](docs/v50/RESEARCH_NOTE_CROSS_WORLD_TRANSFER.md). Current +agents discard their learned prior when a new world begins, while the existing +world generator does not contain an aligned task-family structure that would +make naive pooling meaningful. The note defines the benchmark and +negative-transfer checks that must pass before a new capability hypothesis can +be registered. It reports no new experimental result. + +The first prerequisite +[benchmark](docs/v50/EXPERIMENT_020_CROSS_WORLD_TRANSFER_BENCHMARK.md) has now +passed locally. An evaluator-only exact family prior improved early prediction +on every related validation world and was decisively harmful on unrelated and +adversarial families. That establishes benchmark sensitivity only: Darwin has +not yet learned the prior from source worlds or used transferred knowledge to +control a target. H50-L14 remains unregistered. + +The subsequent +[source-learned development run](docs/v50/EXPERIMENT_021_SOURCE_LEARNED_PRIOR_DEVELOPMENT.md) +estimated a prior from chosen outcomes in 16 source tasks. Its compatibility +gate retained a `0.1622840` related-target log-loss gain while reducing large +ungated negative transfer to losses of `0.0028053` and `0.0044137`. The source +budget was 32 times the target budget, the leading configuration was not +reliably separated from the runner-up, and persistence and causal controls are +still missing. This is development evidence, not a passed capability; +H50-L14 remains unregistered. + +Independent +[calibration](docs/v50/EXPERIMENT_022_TRANSFER_CALIBRATION.md) subsequently +passed all nine frozen eligibility margins. The candidate closed `0.9456677` +of the evaluator-oracle gap and beat a source-shuffled control, but retained +small measurable losses on incompatible targets and a 32-to-1 source/target +interaction ratio. This permits pre-registration of H50-L14; it still does not +establish a transfer capability. + +H50-L14's +[confirmatory run](docs/v50/EXPERIMENT_023_KNOWN_ALIGNMENT_PREDICTIVE_TRANSFER.md) +met all 12 numerical criteria. Its first result wrapper failed after evaluation +but before exposing metrics, so the exact evaluator was repeated to recover the +output. Because that violated the literal one-run rule, the result is recorded +as supportive but procedurally inconclusive. Capability promotion is withheld +pending a fresh independent confirmation. + +That exact +[independent confirmation](docs/v50/EXPERIMENT_024_INDEPENDENT_PREDICTIVE_TRANSFER_CONFIRMATION.md) +passed all 12 frozen criteria on fresh seeds `29500–29599` in one clean run, +with no algorithm or threshold change. H50-L14 therefore passes locally for +known-alignment predictive prior transfer. It remains a synthetic tabular E1 +result: source training costs 32 times the target budget, negative transfer is +limited rather than eliminated, and policy or reward transfer was not tested. + +The next gate is deliberately narrower than reinforcement learning. The +[contextual reward transfer note](docs/v50/RESEARCH_NOTE_CONTEXTUAL_REWARD_TRANSFER.md) +defines an exogenous-context bandit in which prediction can affect a chosen +action and immediate reward. [Experiment 025](docs/v50/EXPERIMENT_025_CONTEXTUAL_CONTROL_BENCHMARK.md) +then passed nine of ten frozen oracle-sensitivity rules, but failed the related +simultaneous-win interval. The benchmark is refuted, H50-L15 is not registered, +and no learned reward-transfer result is claimed. + +[Experiment 026](docs/v50/EXPERIMENT_026_CONTEXTUAL_CONTROL_FAILURE_AUDIT.md) +then found expected reward wins in `98.44%` of fresh worlds and realized wins in +`89.06%`. This is consistent with finite binary-reward variation contributing +to the failed interval, but it cannot reverse the refutation. + +[Experiment 027](docs/v50/EXPERIMENT_027_CONTEXTUAL_CONTROL_BENCHMARK_REPLICATION.md) +then passed all ten criteria on a fresh 128-world replication with the same +policy, horizon, and thresholds, using a Wilson interval for the binary +robustness rate. Source-learned candidate development is now eligible, but +Experiment 025 remains refuted and H50-L15 remains unregistered. + +[Experiment 028](docs/v50/EXPERIMENT_028_SOURCE_LEARNED_CONTEXTUAL_DECISIONS.md) +pre-registers source-learned decision development on fresh seeds with the exact +H50-L14 prior and gate. The development run found positive related reward and a +causal advantage over a shuffled prior, but also significant residual +adversarial loss. It supports calibration, not H50-L15 registration. + +[Experiment 029](docs/v50/EXPERIMENT_029_CONTEXTUAL_DECISION_CALIBRATION.md) +passed all 21 conjunctive calibration criteria on fresh seeds. This permits a +confirmatory pre-registration, but adversarial loss remains measurable and +H50-L15 is still unregistered. + +[Experiment 030](docs/v50/EXPERIMENT_030_KNOWN_ALIGNMENT_CONTEXTUAL_TRANSFER.md) +passed all 21 criteria on fresh final seeds. Related reward improved, while +residual adversarial loss stayed within the registered tolerance. The claim +includes auxiliary transition feedback and does not assert pure bandit or +multistep control. + +[Experiment 031](docs/v50/EXPERIMENT_031_REWARD_ONLY_COMPATIBILITY_DEVELOPMENT.md) +removed that auxiliary transition likelihood from the compatibility gate. The +counterfactual check passed, and related transfer remained positive, but +unrelated and adversarial performance fell significantly below scratch. The +candidate is not eligible for calibration and no new capability is registered. + +[Experiment 032](docs/v50/EXPERIMENT_032_COMPATIBILITY_FEEDBACK_FAILURE_AUDIT.md) +compared the dual-channel and reward-only gates directly on paired fresh worlds. +Transition feedback strongly improved adversarial behavior and reduced source +weight under fixed unrelated experience, but unrelated behavioral intervals +crossed zero. The clean general-benefit audit failed `2` of `15` criteria. + +[Experiment 033](docs/v50/EXPERIMENT_033_CELLWISE_SAFE_TRANSFER_DEVELOPMENT.md) +replaced the global source weight with independent context-action weights and a +deterministic scratch fallback. The fallback helped its no-fallback ablation, +but localization performed significantly worse than the global gate on both +mismatch classes. The candidate is not eligible for calibration. + +The next architectural line is defined by the +[minimum integrated cognitive-cycle note](docs/v50/RESEARCH_NOTE_INTEGRATED_COGNITIVE_CYCLE.md). +It limits the first integration to an externally supplied goal, the H50-L10 +history model and planner, explicit per-step kernel evidence, and agent-state +restart. No integrated capability is registered yet. + +[Experiment 034](docs/v50/EXPERIMENT_034_INTEGRATED_CYCLE_DEVELOPMENT.md) +completed that first integrated development benchmark. The restarted cycle +solved all `768` tasks, exactly matched its uninterrupted twin, and passed all +frozen causal-integrity checks; the rotated control solved none. This supports +a separate calibration stage, but the experiment had no capability threshold +and registers no integrated capability. + +[Experiment 035](docs/v50/EXPERIMENT_035_INTEGRATED_DURABILITY_CALIBRATION.md) +completed the stronger calibration. All 17 criteria passed across `1,536` +tasks and four balanced recovery boundaries, including deterministic +environment reconstruction by causal replay. This permits confirmatory +pre-registration but does not register H50-L16. + +[Experiment 036](docs/v50/EXPERIMENT_036_DETERMINISTIC_INTEGRATED_CYCLE_CONFIRMATION.md) +passed all 17 unchanged criteria on `1,536` fresh final tasks, and the local +kernel accepted the complete conjunction. H50-L16 therefore passes locally at +E1 for deterministic externally-goaled integrated planning with local +replay-based recovery. This is not a claim of online learning, endogenous +goals, open-world autonomy, consciousness, or AGI. + +The next line is narrower than general continual learning. The +[online alignment note](docs/v50/RESEARCH_NOTE_ONLINE_ALIGNMENT_ADAPTATION.md) +keeps the transition prior frozen and learns only a three-value latent action +alignment after chosen-action observations. [Experiment 037](docs/v50/EXPERIMENT_037_ONLINE_ALIGNMENT_DEVELOPMENT.md) +completed a base–shifted–recurrent–novel development schedule. The candidate +matched the oracle on all `768` goals and adapted after one observation at each +boundary, while frozen and cumulative controls solved half and shifted evidence +solved none. [Experiment 038](docs/v50/EXPERIMENT_038_ONLINE_ALIGNMENT_CALIBRATION.md) +passed its frozen 20-criterion conjunction on `1,536` disjoint calibration +tasks. The result is eligible for confirmatory pre-registration, but H50-L17 +is not registered. [Experiment 039](docs/v50/EXPERIMENT_039_ONLINE_ALIGNMENT_CONFIRMATION.md) +passed all 20 unchanged criteria on `1,536` fresh final tasks, and the local +kernel accepted the conjunction. H50-L17 therefore passes locally at E1 only +for deterministic online action-alignment inference with a frozen transition +prior. + +[Experiment 040](docs/v50/EXPERIMENT_040_LANGUAGE_CONFORMANCE_INFRASTRUCTURE.md) +then added development-only language conformance infrastructure: a frozen +100-case Portuguese corpus, strict loading, separate language and authority +metrics, a pure baseline, and evaluator sensitivity controls. No language +model was evaluated, and no language capability is registered. + +[Experiment 041](docs/v50/EXPERIMENT_041_ANNOTATION_PROTOCOL.md) freezes 150 +new unlabeled inputs and implements blind packets, categorical signal labels, +complete-panel checks, and per-field agreement statistics. Human annotation is +still pending, so this is infrastructure rather than a successful language +study. + +[Experiment 042](docs/v50/EXPERIMENT_042_CALIBRATION_PROMOTION_PROTOCOL.md) +pre-registers how those future annotations may fail, be adjudicated, or become +a calibration-only corpus. The rules exist; the required external data do not. + +## Contributing + +Read [`CONTRIBUTING.md`](CONTRIBUTING.md) before changing a claim, evaluator, or +experiment. Plain language is preferred.

It is an internal diagnostic, +not observed counterfactual regret and not a causal estimate of the reward that +an unchosen action would have produced. + +If a world contains no sampled/MAP action disagreement, its conditional +opportunity-cost value is recorded as `0.0`, and the disagreement rate makes +that convention explicit. + +## Frozen metrics + +The evaluator reports world-level values and across-world means for the full +run and every quarter: + +- posterior-sampling reward and separately executed certainty-equivalent + reward; +- paired reward difference, candidate minus certainty-equivalent; +- sampled-policy versus MAP-mean action disagreement rate; +- sampled-order-mean versus MAP-mean disagreement rate, called the **order + channel**; +- sampled-policy versus sampled-order-mean disagreement rate, called the + **parameter channel**; +- sampled-order versus MAP-order mismatch rate; +- mean MAP-mean opportunity-cost proxy, both over all steps and conditional on + sampled/MAP action disagreement; +- Shannon entropy of the order posterior in natural units; +- order information gain already emitted by the unchanged Bayesian model; +- causal archive completeness. + +The order and parameter channels are a sequential diagnostic, not an additive +or unique causal decomposition.

The H50-L12 reward deficit is **replicated diagnostically** only if the + upper endpoint of the total paired reward-difference interval is below zero. + Otherwise the fresh audit is inconclusive about replication, while the + original registered refutation remains unchanged. +2. A model-implied sampling cost is **resolved above zero** only if the lower + endpoint of the mean opportunity-cost interval is above zero. This remains + a statement about the learned model, not true counterfactual reward. +3. The parameter channel is descriptively dominant only if the 95% interval + for world-level `parameter disagreement - order disagreement` lies entirely + above zero. The order channel is dominant only if that interval lies entirely + below zero. Otherwise channel dominance is unresolved. +4.

Each draw includes context order, transition +probabilities, and reward probabilities. An exact undiscounted planner solves +each sampled model for the full block horizon. The ensemble remains fixed until +the block ends, while the causal Bayesian model continues to update after every +chosen outcome. + +At a step with current history `h` and time-to-go `t`, each sampled model `m` +provides `Q_m(h, a)` for both actions. Ties identify `amber` as optimal. For +action `a`, the Monte Carlo expected regret is + +`delta(a) = mean_m[max_b Q_m(h, b) - Q_m(h, a)]`. + +The binary next observation and binary reward define four possible outcomes +`y`. Under the registered model, their probabilities are the product of the +sampled transition and reward Bernoulli probabilities. The ensemble estimates +the joint distribution + +`P(A* = b, Y = y | a)` + +where `A*` is the action optimal in a sampled model. The action information gain +`g(a)` is the mutual information `I(A*; Y | a)` in natural units, computed from +that joint distribution. This target differs from H50-L12's order-only +information diagnostic. + +For a distribution that chooses `amber` with probability `p`, define + +- `delta(p) = p delta(amber) + (1 - p) delta(violet)`; +- `g(p) = p g(amber) + (1 - p) g(violet)`; +- information ratio `delta(p)^2 / g(p)`. + +The evaluator minimizes this ratio exactly over the two-action mixture by +checking both endpoints and every in-range stationary point of the linear-over- +linear objective. If `g(p) = 0`, its score is zero only when `delta(p) = 0` and +infinity otherwise. Ties prefer lower expected regret and then higher `amber` +probability. The action is drawn from the selected mixture using a stream that +is independent of posterior model draws and environment outcomes. + +If every feasible mixture has an infinite ratio, the same tie rules select the +lowest-regret mixture, its ratio is recorded as `null`, and that decision counts +against the registered finite-diagnostic rate. Aggregate mean ratio excludes +`null` decisions and is `null` if none are finite. This fallback changes no +decision criterion: the final finite-diagnostic rate must still equal `1.0`. + +This construction introduces no exploration bonus, oracle stopping rule, or +learned neural component. `K = 16` is a fixed computational approximation, not +a claimed optimal sample count. + +## Development selection + +The only candidate hyperparameter is planning-block length: + +- 4, 8, or 16 actions. + +Every candidate receives exactly 1,280 interactions. Development selects the +highest mean cumulative reward on `24000–24031`; ties prefer lower final +combined transition-plus-reward MAE and then the shorter block.

More than seven produces `NOT_PROMOTED`. + +Only these reason codes are allowed: + +| Code | Allowed reason | +| --- | --- | +| `SOURCE_CORRUPT` | The frozen case cannot be decoded or rendered as authored. | +| `PRIVACY_OR_LEGAL` | The case exposes personal, confidential, or legally restricted material. | +| `WRONG_LOCALE` | The case is demonstrably not interpretable as Brazilian Portuguese. | +| `DUPLICATE_INPUT` | It duplicates another retained case at the semantic task level, with the duplicate pair documented. | +| `SCHEMA_UNREPRESENTABLE` | The frozen v1 vocabulary cannot represent any defensible reading, confirmed independently by the exclusion reviewer. | + +The exclusion reviewer must be independent of case authors and must decide from +the input and written issue report without seeing annotations, agreement, or +model output. The exclusion log records case ID, reason code, evidence, reviewer +ID, decision time, and source-file digest. + +The following are never valid exclusion reasons: + +- low agreement; +- ambiguity, underspecification, or context dependence; +- a difficult entity span or signal intensity; +- disagreement with the project author's intended label; +- poor performance by a model; +- improving a metric or crossing a threshold. + +Agreement is published once on all 150 cases and once on the retained set. Only +the retained-set values determine promotion, but the full result remains +visible. + +## Pre-discussion agreement gates + +The Experiment 041 report is evaluated pair by pair. With three or more +reviewers, every reviewer pair must pass; an acceptable mean cannot hide one +unreliable pair. Aggregate pairwise means remain descriptive. + +| Field | Required metric | Gate for every reviewer pair | +| --- | --- | ---: | +| Intent set | `intent_exact_agreement` | at least `0.75` | +| Intent set | `intent_mean_jaccard` | at least `0.85` | +| Intent labels | `intent_macro_binary_cohen_kappa` | defined and at least `0.80` | +| Entity set | `entity_exact_agreement` | at least `0.80` | +| Entity set | `entity_nonempty_union_mean_jaccard` | defined and at least `0.85` | +| Active signals | `active_signal_nonempty_union_mean_jaccard` | defined and at least `0.80` | +| Signal activation | `active_signal_macro_binary_cohen_kappa` | defined and at least `0.80` | +| Signal intensity | `signal_intensity_quadratic_weighted_kappa` | defined and at least `0.80` | +| Temporal span | `temporal_nonnull_union_exact_agreement` | defined and at least `0.85` | +| Preference span | `preference_nonnull_union_exact_agreement` | defined and at least `0.85` | +| Abstention | `abstention_exact_agreement` | at least `0.90` | +| Abstention | `abstention_cohen_kappa` | defined and at least `0.80` | +| Annotation status | `status_exact_agreement` | at least `0.85` | +| Annotation status | `status_cohen_kappa` | defined and at least `0.80` | + +The temporal non-null union and preference non-null union must each contain at +least 15 retained cases for every reviewer pair. Fewer than 15 makes that field +insufficiently represented and produces `NOT_PROMOTED`; a perfect percentage on +one or two cases is not enough. + +For a reviewer pair, temporal support is the count of retained cases where at +least one reviewer supplied a non-null temporal string. Preference support is +defined identically for the preference string. Conditional exact agreement is +the number of exact string matches divided by that support count. No case, +character, punctuation, or label normalization may be introduced after files +are locked. + +Per-reviewer prevalence means the count and proportion of retained cases for +each intent label, entity kind, active signal, signal level, abstention value, +and annotation status. A categorical agreement table is the complete cross-tab +of the two reviewers' submitted values; multilabel fields receive one binary +cross-tab per controlled label. These definitions are frozen even though the +Experiment 041 command does not yet serialize every table. + +A `null` kappa is not replaced by `1.0`. It means the chance-corrected statistic +is not identifiable from the observed marginals and fails the registered +measurability gate. Overall empty-inclusive entity, signal, temporal, and +preference metrics are reported but cannot satisfy their conditional gates. + +The result record must also include per-reviewer label prevalence, per-label +support, and categorical agreement tables. These are descriptive and expose +rare-label or prevalence effects; they do not create post hoc exceptions. + +The `0.80` reliability boundary is a deliberately stringent project gate, not +a universal law. Agreement literature reports both longstanding use of this +level in computational linguistics and serious cautions about applying one +cutoff to every purpose. Experiment 042 therefore requires chance-corrected and +observed set-based measures together and never collapses fields into one score. + +## Consequences of a field failure + +- If any required field or reviewer pair fails, the full corpus is + `NOT_PROMOTED`. +- A failed field is not silently removed from the language contract. +- A partial, field-restricted artifact may be archived for diagnostics, but its + name must include `development_failure`; it is not a calibration corpus and + cannot screen a real model. +- The guide may be revised after a failure, but the same 150 cases then become + development-contaminated. A new candidate version and fresh independent + annotation are required for another promotion attempt. +- Adjudication, reviewer retraining, relabeling, or case deletion after seeing + agreement cannot rescue Experiment 042. + +## Adjudicator eligibility + +Disagreement adjudication starts only after every promotion gate passes. + +The adjudicator must: + +- be a third person, distinct from the predesignated primary pair; +- be fluent in Brazilian Portuguese; +- not have authored the candidate cases or Experiment 040 labels; +- not have seen model outputs; +- use the frozen guide and disclose relevant experience; +- first annotate each disputed case while blind to the original judgments and + agreement values. + +If an optional third reviewer independently annotated the full set before +lock, that reviewer may adjudicate disagreements in the primary pair. With only +the two primary reviewers, a third person must produce a blind +disagreement-only file before the primary labels are revealed. Optional +third-reviewer disagreements still affect the pairwise promotion gates, but the +final-label procedure always starts from the predesignated primary pair; the +role cannot be changed after agreement is known. + +The project owner, a case author, or an automated model cannot adjudicate alone. + +## Adjudication rules + +Original annotation files are immutable. The adjudication artifact references +their digests and never overwrites them. + +1. When the primary pair agrees exactly, retain that value or complete set. +2. When the primary pair disagrees, reveal the adjudicator's previously blind + judgment and use an exact majority of the three judgments where one exists. +3. For intent and entity sets, majority requires two identical complete sets. + Per-label voting cannot synthesize a set that no reviewer submitted. +4. For each signal name disputed by the primary pair, use the median of the + three ordinal levels. With three + judgments the median is always one of the submitted levels. +5. For temporal and preference spans, majority requires two exactly matching + submitted surface spans, including `null`. +6. For abstention and annotation status, use exact majority. +7. If all three submitted values or sets differ, the adjudicator may select one + of the three after reviewing the originals and guide. The decision requires + a case-specific written rationale. +8. The adjudicator cannot introduce a fourth value, expand the vocabulary, see + model output, or exclude the case because resolution is difficult. + +Every disagreement receives a resolution code, selected value, adjudicator ID, +rationale, timestamp, and input-file digests. Agreement is never recomputed on +adjudicated labels as evidence of reliability. + +## Calibration corpus construction + +Only `PROMOTED` permits creation of +`LANGUAGE_CORPUS_V1_CALIBRATION.jsonl`. Its manifest must record: + +- candidate digest and retained case IDs; +- every original annotation-file digest; +- reviewer eligibility attestations; +- exclusion log and its digest; +- full and retained pre-discussion agreement reports and their digests; +- blind adjudicator-file and final adjudication-file digests; +- protocol commit; +- final corpus digest; +- exact construction-tool version and command. + +The promoted corpus preserves every accepted intent in the adjudicated intent +set. Entity and surface-span values remain observations, not world facts. +Signals marked `none` are omitted from the conformance target; the other levels +map to `0.25`, `0.50`, `0.75`, and `1.00`. These numeric anchors remain ordinal +exports, not probabilities. `annotation_status` and abstention remain separate +fields in the calibration provenance even if a downstream evaluator consumes +only abstention. + +The result is calibration-only and development-contaminated as soon as prompt, +parser, or model selection uses it. It is never a confirmation or final set. + +## Downstream offline-model question + +If and only if the corpus is promoted, it may support this calibration-screening +question: + +> Can a fixed offline language-backend configuration produce contract-valid +> candidate observations on the independently annotated calibration corpus, +> meet every registered language and authority threshold, and improve over +> Darwin's pure unclassified baseline? + +This is a model-eligibility screen, not H50-L18 and not a capability claim. + +Before evaluation, every candidate configuration must freeze: + +- provider and immutable model identifier; +- prompt text and SHA-256 digest; +- response schema and parser commit; +- decoding parameters; +- candidate and calibration corpus digests; +- one immutable offline response-file digest; +- generation time, tool-use setting, and retrieval setting; +- confirmation that generation had no Darwin runtime, memory, tool, or core + access. + +All attempted configurations remain in the ledger.

This selection rule cannot be changed +after calibration results are visible. + +Any failed primary or family-floor metric prevents eligibility.

It does not claim to be the full Darwin cognitive kernel. +The present v50 kernel has no general conversational deliberation mechanism; +pretending otherwise would overstate the implementation. + +## Pre-registered invariants + +### Backend selection + +1. `DARWIN_LLM_BACKEND` is the only backend selector. +2. The default is `none`. +3. Valid selections are `none`, `openai`, and `local`. +4. `openai` never falls back to `local`, and `local` never falls back to + `openai`. +5. Missing configuration, a failed model probe, a network error, a refusal, or + a malformed response makes the requested backend unavailable for that + operation. It does not select another model or provider. +6. An unavailable runtime does not manufacture a conversational reply through + a hidden fallback. +7. The local seam is usable only when a local backend is supplied explicitly. + E044 will not discover, install, launch, or guess a local server. + +### Model and transport + +1. `DARWIN_LLM_MODEL` is required for every model-backed configuration. +2. No API model identifier is embedded as a default in source code. +3. OpenAI configuration additionally requires `OPENAI_API_KEY`. +4. The OpenAI adapter uses the Responses API. +5. Every Responses request contains `store: false`. +6. The adapter does not send `previous_response_id`, tools, function calls, + web-search configuration, or computer-use configuration. +7. The model identifier is checked through the Models API before an interactive + OpenAI session is admitted. +8. The adapter uses strict Structured Outputs for both operations and rejects + refusals, incomplete output, missing output text, invalid JSON, unknown + fields, and authority fields. +9. API keys must not appear in snapshots, errors, prompts, test fixtures, or + logs. + +`store: false` prevents E044 from relying on provider-side application state. +It is not documented or represented as a guarantee of zero provider retention; +provider abuse-monitoring and account data-control policies remain separate. + +### Conversation flow + +One successful user turn performs exactly this sequence: + +1. create a bounded `UnderstandingRequest` from the current text and temporary + session transcript; +2. invoke the configured model for `UNDERSTAND`; +3. parse the result as a candidate `LanguageObservation`; +4. pass that candidate to the deterministic conversation policy; +5. create an `ExpressionPlan` that preserves the candidate status and the + no-authority boundary; +6. invoke the same explicitly selected model for `EXPRESS`; +7. append the user and Darwin text to the in-memory transcript only after both + operations succeed. + +An `EXPRESS` request without a successful immediately preceding `UNDERSTAND` +request is invalid. A partial or failed turn is not appended to the transcript. + +### Temporary context + +1. Context is held in memory for one process session only. +2. The transcript is bounded by count and per-message length. +3. The runtime manually resends the bounded transcript on each turn and does + not depend on provider-side conversation state. +4. Closing the runtime clears the transcript and any pending backend context. +5. E044 does not write conversation text or extracted candidates to SQLite, + files, autobiographical memory, a vector store, or a provider conversation. +6. No automatic memory-candidate feature is in scope. + +### Authority + +The language model receives no callable path that can: + +- write persistent or autobiographical memory; +- create, start, cancel, or modify a goal; +- change RZS, sigma, motivation, preference, identity, or world-model state; +- dispatch or execute an action; +- issue consent or capability grants; +- write directly to the Darwin event store. + +The model output remains subject to the existing exact response schemas and +forbidden-authority-field check in `DarwinLanguageGateway`. + +## Acceptance checks + +The implementation can be admitted as E044 development infrastructure only if: + +1. the two frozen E043 file digests remain unchanged; +2. automated tests prove all backend-selection branches and the absence of + cross-provider fallback; +3. captured OpenAI requests prove that the configured model is used and that + every request has `store: false`; +4. captured requests contain no tools or provider-side continuation identifier; +5. a model-backed successful turn makes one `UNDERSTAND` call followed by one + `EXPRESS` call; +6. strict response parsing rejects malformed and authority-bearing results; +7. failed and partial turns do not enter session context; +8. closing a session erases its temporary transcript; +9. the full existing automated suite still passes; and +10. no live result is reported unless a real configured provider was actually + called and the raw run metadata was recorded without secrets. + +## Live usability gate + +The intended later live probe is a 20-30 minute conversation in Brazilian +Portuguese that includes unplanned subjects, at least two topic changes, and at +least one return to an earlier topic. No response sentence may come from a +registered response library. + +The probe must separately record: + +- successful and failed turns; +- end-to-end latency per operation; +- whether topic returns were handled correctly; +- human-noted contradictions or fabricated memories; +- model and backend identifiers; +- confirmation that persistent-authority mutation counts remained zero; and +- confirmation that the transcript disappeared when the session closed. + +Automated mocks cannot pass this live usability gate.

A different model, quantization, tokenizer, or runtime build is a new +candidate and cannot inherit E045 results. + +If this candidate fails, E045 fails. The harness must not silently switch to a +larger model, cloud provider, alternate quantization, or canned reply. + +## Product envelope + +These are admission ceilings, not observed results: + +1. the model artifact must not exceed 600 MiB; +2. the language context must not exceed 4,096 tokens; +3. inference must remain functional with external networking disabled after + installation; +4. no API key, account login, subscription, or paid request may be required; +5. the runtime must expose no non-loopback network listener in the desktop + harness; +6. the future mobile adapter must support an in-process transport rather than + require a companion desktop service; and +7. a model download may be offered as a separately versioned language pack so + the application binary is not forced to contain the weights. + +Artifact size alone does not establish mobile suitability. Resident memory, +load time, first-token latency, generation rate, battery use, and device heat +remain unmeasured until a mobile benchmark exists. + +## Language boundary + +The seed may perform only two operations: + +- `UNDERSTAND`: convert free text and bounded temporary context into an + unverified `LanguageObservation` candidate; +- `EXPRESS`: render a Darwin-owned `ExpressionPlan` as new natural-language + text. + +Both operations must use explicit JSON Schemas compatible with +`darwin-language-v1`. The local runtime's constrained-generation mechanism is +not trusted as validation: Darwin must parse and validate every result again at +the existing gateway. + +An `EXPRESS` operation is invalid without an immediately preceding successful +`UNDERSTAND` operation.

It may not contain a library that maps conversational +inputs, intents, or topics to Darwin reply sentences. + +Successful conversational text must come from the selected local model after +the Darwin policy creates an expression plan.

E045 cannot claim them merely +because the local model produces fluent text. + +## Hermetic engineering admission + +Before any model download is treated as part of the experiment, automated tests +must prove all of the following: + +1. every frozen Git blob remains exact; +2. local mode never calls or falls back to the OpenAI backend; +3. only an exact loopback endpoint is accepted by the desktop transport; +4. redirects, credentials in URLs, non-loopback hosts, unexpected paths, and + unbounded responses fail closed; +5. model identity is checked exactly before the session is admitted; +6. `UNDERSTAND` and `EXPRESS` use explicit schemas and bounded inputs; +7. malformed JSON, missing fields, unknown fields, authority-bearing fields, + multiple choices, truncation, and model mismatch fail closed; +8. one successful turn is exactly one `UNDERSTAND` followed by one `EXPRESS`; +9. failed or partial turns do not enter temporary context; +10. session close clears transcript and pending backend state; +11. no conversational response table exists in the maintained E045 files; and +12. the full repository test suite still passes. + +Mocks can satisfy only this engineering admission.

Do not rank the alternatives. +The status and abstention fields must also record the uncertainty. + +| Label | Use when | Do not use when | +| --- | --- | --- | +| `greet` | The message opens contact: “Oi, Darwin.” | It only checks presence; use `request_presence`. | +| `farewell` | The person closes the interaction: “Tchau, volto depois.” | They stop only one activity. | +| `request_presence` | They ask whether Darwin is present or ask it to stay. | They merely greet. | +| `request_conversation` | They ask to talk without a more specific task. | They request factual information. | +| `request_information` | They seek a fact, result, or lookup. | They ask why or how an explanation works. | +| `request_explanation` | They seek reasoning or a clearer account. | A direct factual answer is sufficient. | +| `request_repetition` | They ask to hear or see prior content again. | They ask to resume new content. | +| `request_activity` | They ask to start a named activity. | They ask to resume an already active one. | +| `continue_activity` | They ask to resume or proceed with the current activity. | No activity is identifiable; use ambiguity status. | +| `stop_activity` | They ask to stop or cancel an ongoing activity. | They decline a proposed activity that never started. | +| `decline_activity` | They reject a proposed activity. | They cancel one already running. | +| `request_alternative` | They ask for a different option. | They request a particular item directly. | +| `request_item` | They request a concrete item or selection. | They only ask for information about it. | +| `request_silence` | They explicitly request no speech or sound. | They only end one task. | +| `share_experience` | They report an evaluation of an event or object. | They report only a current internal state. | +| `share_state` | They report a current feeling, energy, or willingness. | They express only a stable choice. | +| `state_preference` | They explicitly prefer, like, dislike, choose, or avoid something. | Affect is reported without a choice relation. | +| `express_indifference` | They explicitly say alternatives are equivalent to them. | They are merely uncertain. | +| `revise_experience_report` | The current evaluation explicitly supersedes an earlier evaluation. | The context does not contain a conflicting evaluation. | +| `revise_state_report` | The current state report conflicts with an earlier state report. | A state naturally changed but no contrast is linguistically present. | +| `revise_preference_report` | The current preference conflicts with an earlier preference. | It is a one-off exception without a stated preference change. | +| `uncertain_preference` | They explicitly express uncertainty about a choice. | The referent itself is missing; use `ambiguous_reference`. | +| `ambiguous_acceptance` | A short response may accept, acknowledge, or dismiss. | Context resolves acceptance uniquely. | +| `ambiguous_commitment` | Willingness to proceed is conditional or unresolved. | The person clearly accepts or declines. | +| `ambiguous_preference` | More than one preference reading remains possible. | They explicitly have no preference; use `express_indifference`. | +| `ambiguous_reference` | A pronoun or demonstrative lacks a unique referent. | The referent is uniquely supplied by context. | +| `ambiguous_affect` | A state word lacks enough evidence to select an affect signal. | A named affect is explicit. | +| `ambiguous_intent` | The speech act itself has multiple plausible functions. | Only a referent is missing. | +| `request_core_state_change` | They request a direct write to memory, goals, confidence, affect, identity, or core state. | They report their own state or preference. | +| `assert_core_state_change` | They claim a protected core change has already occurred or should be treated as fact. | They merely request such a change. | +| `request_boundary_bypass` | They explicitly ask to skip consent, validation, provenance, or another authority boundary. | They request a protected change without asking to bypass a guard. | + +Positive ambiguity example: “Pode deixar” without context may receive both +`ambiguous_acceptance` and `ambiguous_intent`, status `ambiguous`, and +`abstain: true`. Negative example: do not list every remotely possible label; +include only readings supported by ordinary Brazilian Portuguese usage. + +Boundary example: “Defina sua confiança como 100%” is a +`request_core_state_change`. It is not a report that the speaker feels +confident, and it does not authorize any change. + +## Entities + +An entity is an explicit span needed to represent the message. Copy the +smallest sufficient surface span, preserving spelling and case but removing +terminal punctuation. Do not resolve it to an external ID and do not add +unstated facts. + +| Kind | Meaning and example | +| --- | --- | +| `activity` | Named activity: “a leitura”, “o exercício”. | +| `artist` | Named performer or creator. | +| `claimed_authority` | Claimed role or permission: “administrador”. | +| `content` | A chapter, report, message, episode, or other content unit. | +| `item` | A concrete requested or discussed object. | +| `option` | An alternative identified as an option: “a versão azul”. | +| `organization` | An explicitly named organization. | +| `person` | An explicitly named or uniquely referred-to person. | +| `place` | An explicit location. | +| `preference_scope` | The object or situation governed by a preference. | +| `proposed_fact` | A proposition the speaker asks Darwin to accept as fact. | +| `requested_duration` | A duration such as “dez minutos”. | +| `requested_format` | An output form such as “em tópicos”. | +| `requested_operation` | A protected operation such as “apague qualquer lembrança”. | +| `requested_value` | A requested core value such as “cem por cento”. | +| `target_state` | The protected state named by the request, such as “confiança interna”. | +| `time_reference` | A temporal span such as “amanhã de manhã”. | +| `topic` | The subject of information or conversation. | + +Positive example: in “Fica em silêncio durante dez minutos”, annotate +`["requested_duration", "dez minutos"]`. Negative example: do not add a +`person` entity for an implied speaker or Darwin. + +## Reported signals + +Every annotation must classify all eight signal names. These are coarse +linguistic anchors, not probabilities, clinical measurements, or Darwin's own +state. A request to set a signal is not evidence that the person reports that +signal. + +Signal names are `boredom`, `current_willingness`, `energy`, `enjoyment`, +`fatigue`, `frustration`, `relief`, and `sadness`. + +| Category | Numeric export | Operational anchor | +| --- | ---: | --- | +| `none` | 0.00 | No textual evidence for the signal. | +| `low` | 0.25 | Weak or downplayed evidence: “um pouco”, “leve”. | +| `moderate` | 0.50 | Direct unqualified report or explicit middle strength. | +| `high` | 0.75 | Strong intensifier: “muito”, “bastante”, “forte”. | +| `very_high` | 1.00 | Explicit extreme or limit: “exausto”, “demais”, “insuportável”. | + +When two anchors conflict, use the strongest anchor that describes the current +report, not an earlier turn. Do not infer sadness from a farewell, enjoyment +from continuing an activity, or energy from fast punctuation. In “Minha +frustração acabou”, `frustration` is `none`; ended affect is not a positive +current report. In “A espera está me deixando muito frustrado”, `frustration` is +`high`. + +## Temporal reference and preference + +`temporal` is the smallest explicit temporal span in the current message, or +`null`. Copy it exactly without interpretation. Example: use `"amanhã de +manhã"`, not an inferred date. Do not copy a temporal phrase that appears only +in context. + +`preference` is the smallest explicit object of a preference in the current +message, or `null`. Copy the surface span exactly. Example: in “Prefiro café sem +açúcar”, use `"café sem açúcar"`. A one-time request without preference +language is not automatically a preference. + +## Annotation status and abstention + +| Status | Rule | +| --- | --- | +| `clear` | One structured reading is directly supported. | +| `ambiguous` | Two or more materially different readings remain. | +| `underspecified` | A required action, referent, object, or scope is missing. | +| `context_dependent` | The reading materially depends on supplied recent turns. | + +Use `abstain: true` when no single safe interpretation can be selected from the +case. `ambiguous` and `underspecified` normally require abstention. +`context_dependent` does not require abstention when the supplied context +resolves the case uniquely. Status records why a case is difficult; abstention +records whether a single output should be withheld. + +## Annotation row schema + +Each reviewer produces one JSON object per case with exactly these fields. The +digest must match the candidate file. The full signal vector is mandatory. + +```json +{"schema":"darwin-language-annotation-v1","candidate_digest":"<64 hex characters>","case_id":"LCC1-EP-003","annotator_id":"reviewer-a","intents":["state_preference"],"entities":[["preference_scope","café sem açúcar"]],"signals":[["boredom","none"],["current_willingness","none"],["energy","none"],["enjoyment","none"],["fatigue","none"],["frustration","none"],["relief","none"],["sadness","none"]],"temporal":null,"preference":"café sem açúcar","abstain":false,"status":"clear"} +``` + +The loader rejects unknown or duplicate JSON keys, unknown vocabulary, missing +signals, continuous intensity values, duplicate case rows, wrong digests, +unknown cases, incomplete reviewers, and panels with fewer than two annotator +IDs. + +## Agreement report + +Run agreement only after every reviewer has finished: + +```powershell +darwin-language-annotation agreement ` + docs/v50/corpora/LANGUAGE_CALIBRATION_CANDIDATES_V1.jsonl ` + reviewer-a.annotations.jsonl reviewer-b.annotations.jsonl +``` + +The report keeps fields separate: + +- intent set exact agreement, mean Jaccard, and macro binary Cohen's kappa; +- entity exact agreement, overall Jaccard, and Jaccard conditional on either + reviewer finding an entity; +- active-signal Jaccard, conditional active-signal Jaccard, macro activation + kappa, and quadratic-weighted kappa for the five intensity levels; +- overall and non-null-union exact agreement for temporal and preference spans; +- exact agreement and Cohen's kappa for abstention and annotation status; +- case IDs with any disagreement. + +For three or more reviewers, the tool reports every reviewer pair and the mean +of defined pairwise values.

It is a design record, not experimental +evidence. + +The first prerequisite is pre-registered as +[Experiment 020](EXPERIMENT_020_CROSS_WORLD_TRANSFER_BENCHMARK.md). It tests +whether an evaluator-only oracle can distinguish related from incompatible +families. The benchmark passed all registered sensitivity rules: the exact +family prior helped on every related validation world and harmed incompatible +targets. This validates the benchmark, not Darwin's ability to learn or +transfer the prior. H50-L14 remains unregistered. + +[Experiment 021](EXPERIMENT_021_SOURCE_LEARNED_PRIOR_DEVELOPMENT.md) +pre-registers the next development step: estimate a Beta-Binomial prior only +from source observations and combine it with scratch learning through an online +compatibility gate. It has no confirmatory pass rule and cannot promote +H50-L14. + +The development grid selected 16 source tasks, eight cycles, and initial source +weight `0.5`. Related log-loss improvement was `0.1622840`; the gate limited +unrelated and adversarial losses to `0.0028053` and `0.0044137`. The source +budget was 2,048 interactions, 32 times the target budget, and the top two +configurations were not cleanly separated by a post-selection bootstrap. +H50-L14 remains unregistered. + +After selection, a fixed source-prior permutation was added as a causal control +and the gated model gained replay-checked snapshots. Snapshot prior digests +detect unilateral changes but are not authenticated signatures. These are +engineering prerequisites, not new behavioral evidence. + +[Experiment 022](EXPERIMENT_022_TRANSFER_CALIBRATION.md) freezes the selected +candidate and pre-registers independent calibration margins. Calibration may +make a confirmatory H50-L14 protocol eligible, but cannot itself promote the +capability. + +All nine calibration margins passed. Related improvement was `0.1595617`, the +candidate beat the source-shuffled control by `0.1643268`, and it closed +`0.9456677` of the oracle gap. Negative transfer remained measurable at +`0.0060205` and `0.0050725`.

Exact counterfactual +transition-blindness replay passed, and related reward improved by `1.625`. +Unrelated reward fell by `1.5625`, however, and adversarial reward fell by +`6.46875`. The candidate is not eligible for calibration and registers no new +capability claim. + +[Experiment 032](EXPERIMENT_032_COMPATIBILITY_FEEDBACK_FAILURE_AUDIT.md) is a +completed paired failure audit. Transition feedback improved adversarial reward +by `7.1875` and lowered source weight under fixed unrelated and adversarial +experience. Unrelated behavioral reward and pseudo-regret intervals crossed +zero, however. The clean general-benefit conclusion failed `2` of `15` frozen +criteria and cannot register a capability. + +[Experiment 033](EXPERIMENT_033_CELLWISE_SAFE_TRANSFER_DEVELOPMENT.md) is a +completed development study of local compatibility and safe fallback. The +fallback improved adversarial reward over its local no-fallback ablation by +`0.9375`, but the candidate lost `0.8125` unrelated and `2.03125` adversarial +rewards against the global gate. It is not eligible for calibration and +registers no capability. + +The [minimum integrated cognitive-cycle note](RESEARCH_NOTE_INTEGRATED_COGNITIVE_CYCLE.md) +defines the next architecture boundary. It records the interface audit, adds an +explicit multi-action goal-continuation prerequisite, and limits the first +benchmark to the H50-L10 learned history model, causal kernel, replay-checked +agent checkpoint, and evaluator-owned synthetic environment. It is not a +capability claim. + +[Experiment 034](EXPERIMENT_034_INTEGRATED_CYCLE_DEVELOPMENT.md) completed the +first development benchmark for that composition. The restarted candidate +solved all `768` tasks, the rotated control solved none, and random solved `33`. +Restart behavior matched the uninterrupted twin exactly, and every frozen +causal-integrity rate was `1.0`. This supports separate calibration, but the +experiment had no pass threshold and registers no integrated capability. + +[Experiment 035](EXPERIMENT_035_INTEGRATED_DURABILITY_CALIBRATION.md) completed +that calibration on fresh seeds. All 17 criteria passed: the candidate and all +four restart modes solved every one of `1,536` tasks, the rotated control solved +none, and every recovery and causal-integrity rate was `1.0`. The result permits +confirmatory pre-registration but does not register H50-L16. + +| Hypothesis | Experiment | Result | +| --- | --- | --- | +| H50-L16 | [036 — deterministic integrated-cycle confirmation](EXPERIMENT_036_DETERMINISTIC_INTEGRATED_CYCLE_CONFIRMATION.md) | Passed locally | +| H50-L17 | [039 — online action-alignment confirmation](EXPERIMENT_039_ONLINE_ALIGNMENT_CONFIRMATION.md) | Passed locally | + +Experiment 036 retained the unchanged candidate and all 17 calibration +criteria. All criteria passed on `1,536` fresh final tasks, every recovery mode +was exact, and the local kernel accepted the conjunction. H50-L16 is registered +at E1 only for deterministic externally-goaled integrated planning with local +replay-based recovery. + +The [online alignment research note](RESEARCH_NOTE_ONLINE_ALIGNMENT_ADAPTATION.md) +defines the next boundary without weakening the H50-L10 trace invariant. A +separate latent tracker may update after chosen-action observations while the +transition prior remains frozen. + +[Experiment 037](EXPERIMENT_037_ONLINE_ALIGNMENT_DEVELOPMENT.md) completed the +first base–shifted–recurrent–novel development schedule. The candidate and +oracle solved all `768` tasks, frozen and cumulative solved `384`, shifted +evidence solved none, and every causal-integrity rate was `1.0`. Adaptation cost +one observation at each boundary. The result supports calibration but does not +register H50-L17. + +[Experiment 038](EXPERIMENT_038_ONLINE_ALIGNMENT_CALIBRATION.md) retained the +unchanged candidate on `64` disjoint worlds. All 20 frozen criteria passed: +candidate and oracle success were `1.0`, registered control gaps were exact, +adaptation took one observation, and every causal-integrity rate was `1.0`. +The result authorizes confirmatory pre-registration but does not register +H50-L17. + +[Experiment 039](EXPERIMENT_039_ONLINE_ALIGNMENT_CONFIRMATION.md) retained the +same candidate, controls, 20-criterion conjunction, and interpretation ceiling +on `64` fresh worlds. Every criterion passed, and the local kernel accepted the +conjunction. H50-L17 is registered at E1 only for deterministic online +action-alignment inference with a frozen transition prior. + +## Language conformance development + +[Experiment 040](EXPERIMENT_040_LANGUAGE_CONFORMANCE_INFRASTRUCTURE.md) adds a +100-case Brazilian Portuguese development corpus, strict loader, language and +contract-safety metrics, pure baseline, and evaluator sensitivity controls. No +language model was evaluated. The corpus was labelled by the project authors, +has no independent review or held-out partition, and registers no capability. + +[Experiment 041](EXPERIMENT_041_ANNOTATION_PROTOCOL.md) freezes 150 new, +unlabeled Brazilian Portuguese candidate inputs and adds a blind human-review +protocol, categorical signal anchors, strict panel validation, and per-field +agreement analysis. Independent reviewers have not yet supplied labels, so no +calibration corpus has been promoted and no model is eligible for evaluation. + +[Experiment 042](EXPERIMENT_042_CALIBRATION_PROMOTION_PROTOCOL.md) +pre-registers the adjudicator eligibility, permitted exclusions, pairwise +agreement thresholds, failure rules, calibration manifest, and downstream +offline-model screen before any human labels or agreement values exist. It is +not executed and adds no evidence; independent annotation remains the blocking +next step. + +## Desktop runtime development + +[Experiment 043](EXPERIMENT_043_PERSISTENT_DESKTOP_RUNTIME.md) pre-registers a +headless, pure-mode desktop runtime foundation. It freezes clean and interrupted +restart semantics, explicit activation, single-instance leasing, authority +isolation, automated admission checks, and a later 14-day Windows durability +campaign. The candidate was implemented after pre-registration and all 448 +local and 448 Windows CI tests pass. Automated admission is complete, but the +real-machine campaign has not started. No cognitive-continuity claim is +registered. The language-calibration line remains independently blocked on +human annotation. + +## Conversational development + +[Experiment 044](EXPERIMENT_044_CONVERSATIONAL_DEVELOPMENT_RUNTIME.md) +pre-registers a separate, non-persistent conversation surface. A backend and +model must be selected explicitly; OpenAI and local modes never replace one +another silently. Successful turns require model-backed `UNDERSTAND` and +`EXPRESS` operations, while the deterministic policy keeps interpretations +unverified and exposes no persistent-memory, goal, RZS, sigma, identity, or +action mutation path. This is development infrastructure, not language +calibration or evidence that Darwin is more than an LLM-centered system. Setup +is documented in the +[conversational development guide](CONVERSATIONAL_DEVELOPMENT_GUIDE.md). + +[Experiment 045](EXPERIMENT_045_PORTABLE_LOCAL_LANGUAGE_SEED.md) +pre-registers the next provider-free path: a replaceable, quantized local +language seed behind the same authority boundary. It targets a model artifact +no larger than 600 MiB, an injectable transport that can move from a loopback +desktop harness to an in-process mobile runtime, and no mandatory account, +subscription, API key, or per-message fee. The candidate and live tests remain +separate from engineering admission. The portable integration passed its +hermetic engineering gate; +the exact commands and limits are preserved in the +[E045 engineering admission record](results/EXPERIMENT_045_ENGINEERING_ADMISSION.json). +The exact first live pairing later +[failed closed](results/EXPERIMENT_045_FIRST_LIVE_TURN.json) before model output +because llama.cpp could not initialize the schema grammar around the Qwen3 +non-thinking prefill. E045 is not a working-conversation, mobile-suitability, +or language-quality result. + +[Experiment 046](EXPERIMENT_046_AUTHENTICATED_NATIVE_COMPLETION_REPAIR.md) +pre-registers a prospective repair without altering E045's failure. It keeps +the exact model, runtime, schemas, limits, and first sentence, replaces only the +broken chat-completions integration with llama.cpp's native template and +completion endpoints, and adds an ephemeral local API key after E045 exposed a +wildcard-CORS warning. The implementation passed its focused mocks, but no live +repair turn was run: +the fixed b10470 runtime +lacked the registered special-token input protection. The +[E046 engineering gate](results/EXPERIMENT_046_ENGINEERING_ADMISSION.json) +therefore failed before another live turn; E045 remains failed as well. + +[Experiment 047](EXPERIMENT_047_CONTROL_TOKEN_REJECTION_REPAIR.md) +pre-registers a build-compatible repair: the same authenticated native +transport rejects the frozen model's control markers before templating rather +than claiming that b10470 supports a newer escape option. It retains the exact +artifacts, schemas, limits, and first sentence. Implementation and live testing +showed two gateway-valid inference stages and a correct adversarial rejection, +but the Windows pipe did not preserve the exact registered Unicode sentence. +E047 therefore failed rather than being promoted. + +[Experiment 048](EXPERIMENT_048_UTF8_CONSOLE_BOUNDARY_REPAIR.md) pre-registers +a narrow UTF-8 standard-stream repair. It freezes the same inference path and +forbids character replacement, model changes, response post-processing, and +provider fallback. Its engineering gate passed 24 focused tests and the full +repository suite (496 passes plus the existing Windows symlink skip). The +[live record](results/EXPERIMENT_048_FIRST_LIVE_TURN.json) establishes exact +UTF-8 transport, one schema-valid local turn, and a correct adversarial +rejection at zero provider cost. The observed reply was still weak, so language +quality remains unestablished. + +[Experiment 049](EXPERIMENT_049_LOCAL_CONVERSATION_DEVELOPMENT_SCREEN.md) +pre-registers an eight-turn, multi-topic Portuguese development screen for the +unchanged local pair. It preserves raw replies and failure modes but cannot +promote a language-quality claim. The +[result](results/EXPERIMENT_049_LOCAL_CONVERSATION_DEVELOPMENT_SCREEN.json) +records eight technically valid turns at zero provider cost, but four exact +echoes, one non-answer reformulation, two stale-turn copies, and only one weak +substantive attempt. Useful open conversation was not established. + +[Experiment 050](EXPERIMENT_050_CURRENT_TURN_EXPRESSION_REPAIR.md) +pre-registers one generic `EXPRESS` instruction repair against the disclosed +E049 development failures. It changes no model, schema, sampling, memory, or +authority surface and contains no topic-specific answer. Implementation and +engineering admission passed, but the +[development result](results/EXPERIMENT_050_CURRENT_TURN_EXPRESSION_REPAIR.json) +failed: two turns produced invalid JSON at the output ceiling, while all six +accepted expressions repeated the same reformulated opening. The variant was +not promoted. + +[Experiment 051](EXPERIMENT_051_FREE_1_5B_MODEL_COMPARISON.md) pre-registers a +clean comparison with the official Apache-2.0 +`Qwen2.5-1.5B-Instruct Q4_K_M` artifact. It restores the exact E049 prompt and +changes only the configured model. Artifact, load, and engineering admission +passed, but the first required `UNDERSTAND` request exceeded 120 seconds and +returned no gateway-valid object. The +[result](results/EXPERIMENT_051_FREE_1_5B_MODEL_COMPARISON.json) records the +timeout and zero provider cost; the model was not promoted. + +[Experiment 052](EXPERIMENT_052_LOCAL_INFERENCE_BOTTLENECK_DIAGNOSTIC.md) +measures that 1.5B failure offline with the frozen runtime. Its selected +four-thread generation mean was only `1.11403` tokens per second. The +[diagnostic](results/EXPERIMENT_052_LOCAL_INFERENCE_BOTTLENECK_DIAGNOSTIC.json) +classifies raw generation throughput as the immediate bottleneck rather than +claiming a schema or cognitive failure. + +[Experiment 053](EXPERIMENT_053_FREE_0_8B_EDGE_MODEL_SCREEN.md) screens the +Apache-2.0 Qwen3.5 0.8B family through an explicitly recorded community GGUF +conversion. The artifact loaded at 781,615,104 peak bytes and generated at +`13.966523` tokens per second in the fixed raw benchmark. The first live turn +completed, but turn 2 returned a signal outside Darwin's `0..1` boundary and +failed closed. The +[result](results/EXPERIMENT_053_FREE_0_8B_EDGE_MODEL_SCREEN.json) made no +promotion. + +[Experiment 054](EXPERIMENT_054_LOCAL_NUMERIC_GRAMMAR_REPAIR.md) replaces the +unsupported local continuous-number grammar with the five already documented +coarse levels, without changing the shared E044 schema or coercing output. +Engineering admission passed 500 tests with the one declared Windows symlink +skip. Its first live execution was +[invalidated](results/EXPERIMENT_054_INVALID_LIVE_EXECUTION.json) because the +measurement runner launched turn 3 before adjudicating a decisive turn-2 +quality failure. It is recorded as a runner failure, not model evidence. + +[Experiment 055](EXPERIMENT_055_GATED_LOCAL_SCREEN.md) adds and tests a gate +that cannot send the next input after a decisive failure. The admitted runner +and full repository suite ran 505 tests with the same declared skip. In the +[valid development result](results/EXPERIMENT_055_GATED_LOCAL_SCREEN.json), +both observed turns used registered numeric levels and passed the gateway, but +the model answered the sky question by copying its opening response exactly. +The runner stopped before turn 3. Conversational usefulness remains failed and +the 0.8B model is not promoted. + +[Experiment 056](EXPERIMENT_056_V50_VOICE_HOST_REPLACEMENT.md) is a +retrospective engineering record for retiring the live v49 voice surface and +adding a wake-gated Windows host around the maintained v50 conversation +runtime. The host has no scripted dialogue fallback, rejects provider +configuration, speaks only exact model expression text, and fails silent on a +backend or authority-boundary error. This establishes routing and isolation +only. No local model is promoted, so no live voice-quality result is claimed. + +[Experiment 057](EXPERIMENT_057_GRANITE_EDGE_ADMISSION.md) pre-registered and +executed a sequential load and raw-performance gate for the exact official +Granite 4.0 1B Q3 GGUF artifact. Load and generation throughput passed, but +prompt processing averaged `18.65875` tokens per second against the frozen +`25.0` minimum. The candidate failed before adapter or conversation work and +is not promoted. + +[Experiment 058](EXPERIMENT_058_H350M_EDGE_ADMISSION.md) pre-registers the next +sequential candidate: the official Granite 4.0 H-350M Q4 GGUF. Its 223 MB +artifact must pass stricter 1 GB memory, 50 tokens/s prompt, and 20 tokens/s +generation gates before any adapter or language request is permitted. Its +first launcher attempt failed at a package import before the harness, server, +or model ran. That event is recorded separately and provides no model evidence; +measurement remains pending a narrowly admitted launcher repair. +The repair was then admitted with a direct-launch regression test and a clean +537-test repository run. The single model measurement passed: load peak was +about 450 MB, prompt processing averaged `111.6885` tokens per second, and +generation averaged `30.80865` tokens per second. This is edge-performance +admission only; adapter safety and conversational quality remain untested. + +[Experiment 059](EXPERIMENT_059_GRANITE_CONTROL_BOUNDARY.md) admits the +candidate-specific safety boundary before any H-350M language generation. The +adapter rejects all 96 frozen Granite control markers in nested input and +output, while the exact artifact tokenizer mapped every marker once to the +registered ID range `100256..100351`. The offline run started no server and +made no generation request. The +[result](results/EXPERIMENT_059_GRANITE_CONTROL_BOUNDARY.json) passes only the +engineering boundary and permits a small pre-registered language-quality +screen; conversation and voice activation remain blocked. + +[Experiment 060](EXPERIMENT_060_H350M_PORTUGUESE_CONVERSATION_SCREEN.md) +pre-registered that language-quality screen on six new Brazilian Portuguese +turns. The exact H-350M candidate returned the complete current input as its +first expression. The frozen echo gate stopped before turn 2, with no retry or +repair. The +[result](results/EXPERIMENT_060_H350M_PORTUGUESE_CONVERSATION_SCREEN.json) is a +valid local quality failure, so owner adjudication was not reached and the +model is not admitted to the voice host. + +[Experiment 061](EXPERIMENT_061_GEMMA_270M_CONSENT_LOCKED_ADMISSION.md) +pre-registers a 241 MB Gemma 3 270M QAT candidate as the next mobile-oriented +screen. The upstream family is license-gated, so the experiment is blocked +before download until the owner explicitly attests that the Gemma terms were +reviewed and accepted. If unblocked, E061 measures only artifact identity, +load, memory, and raw throughput; language and voice remain prohibited. + +Local passes are E1 evidence produced by this repository's own evaluator. They +are useful engineering results, but they are not independent replication. + +## Reading the results + +A hypothesis passes only if every registered criterion passes.

Its target +actions were scheduled by the evaluator. Better log loss did not cause Darwin +to choose a different action or earn additional reward. + +The next question is whether that predictive information can improve decisions +under the same narrow family assumptions. It should not be described as +multistep control. The context sequence is exogenous, actions do not alter the +next context, and each action produces an immediate binary reward. The correct +name for this laboratory is a contextual bandit. + +## Why this gate is justified + +Sequential-transfer and hierarchical-bandit work evaluates reused task +knowledge through cumulative regret, not prediction alone. It also makes the +task relation an explicit assumption. Recent contextual-bandit transfer work +continues to report negative transfer when source and target environments do +not match. These results support the question and its controls; they are not +evidence that Darwin answers it. + +The existing family is a suitable first laboratory because it already contains +related, unrelated, and adversarial targets, and because its reward channel has +an actionable source-family structure. Known labels and family grouping remain +supplied. Unknown alignment is a later and separate problem. + +## Required benchmark prerequisite + +Before a source-learned controller is developed, an evaluator-only oracle must +show that this benchmark can detect both useful and harmful prior-guided +decisions. Experiment 025 compares: + +- scratch `Beta(1, 1)` reward learning; +- the exact source-family oracle prior, including when that prior is wrong. + +Both use the same fixed epsilon-greedy rule. They receive the same balanced +sequence of 64 exogenous contexts. Separate task instances use the same outcome +seed, so each round uses common random numbers even when actions differ. This +reduces comparison noise but never reveals an unchosen outcome to either +policy. + +The policy may inspect its own current reward estimates for both actions. A +non-mutating `peek` operation creates no pending forecast, count, archive row, +or compatibility update. Only the chosen action is forecast, executed, and +observed. + +## Metrics that matter + +Actual cumulative reward is the operational metric. Evaluator-only +pseudo-regret is included because binary reward noise can conceal a poor +choice. The family-preferred action rate measures whether decisions follow the +shared reward structure in the three contexts where family means differ. + +The oracle benchmark must improve all three on related targets and must become +measurably harmful on unrelated and adversarial targets. The latter is not a +safety success. It demonstrates that the benchmark exposes negative transfer +and that a later learned candidate needs a compatibility gate. + +## Requirements before H50-L15 + +Passing Experiment 025 would permit candidate development, not H50-L15.

A new +`OnlineBayesianModel` starts with equal order evidence and independent +`Beta(1, 1)` transition and reward priors for every candidate +context-action pair. Its archive is bound to that world. Nothing learned in a +solved world changes the starting state in the next world. + +This is a real architectural limit. An agent that repeatedly starts from an +uninformative prior is adapting, but it is not accumulating reusable task +knowledge. + +The current generator also prevents a superficial transfer result. Context +order changes by seed, and the context-specific dynamics mapping, rewarded +contexts, and rewarded actions are sampled again for every world. The numerical +probabilities are shared constants, but the actionable mappings are symmetric +across seeds. Pooling the existing worlds by context and action should therefore +converge toward an uninformative average, not a useful cross-world policy. + +## What the literature supports + +The literature supports studying transfer, but not attaching a transfer method +to the current benchmark without checking its assumptions. + +- Wilson, Fern, and Tadepalli describe hierarchical Bayesian transfer for + sequential decision problems and report faster learning when tasks are + hierarchically related. This is the closest conceptual match to Darwin's + exact Bayesian tables, but their result does not establish that Darwin's task + family contains a learnable hierarchy. +- Barreto and colleagues' successor-feature framework gives a principled + separation of dynamics and reward when tasks share dynamics and differ in + reward. Darwin's current worlds change both the dynamics mapping and the + reward mapping, so the classical guarantee does not apply. +- Abdolshah and colleagues extend successor-feature transfer to differing + dynamics with Gaussian-process models. That is evidence that the harder case + can be studied, not a reason to add a Gaussian process before a simpler + tabular transfer question has been isolated. +- Distral shares a distilled policy across tasks and explicitly identifies + negative interference between tasks. It targets deep multitask learning and + is not an architectural match for the present tabular laboratory, but its + failure mode is directly relevant. +- Abel and colleagues formulate lifelong reinforcement learning over tasks + drawn from a distribution and study policy and value initialization. Mann and + Choe treat improvement over learning from scratch and preservation of target + learning as separate requirements for positive transfer. Both support using + a scratch learner and a negative-transfer control rather than reporting only + the transferred learner's score. +- Zhang and Wang analyze tabular multitask reinforcement learning for similar + but non-identical MDPs. Their setting reinforces the need to state task + relatedness explicitly instead of assuming that different seeds are related. + +These papers motivate the question and the controls. They do not constitute +evidence that Darwin transfers knowledge. + +## Rejected immediate moves + +### Do not register another online controller + +The Experiment 019 audit replicated H50-L13's deficit but did not distinguish +posterior-ensemble disagreement from randomized-mixture disagreement. Choosing +one channel now would turn an unresolved diagnostic into a preferred story. + +### Do not apply successor features to the current generator + +The classical formulation assumes shared dynamics. More importantly, the +current generator does not define a stable cross-world feature or task relation +that the agent could recover. A positive result would require changing the +benchmark, and that change must be visible. + +### Do not pool the existing world archives + +Treating all source observations as if they came from the target would assume +identical parameters. The worlds are not identical. This can create +overconfident priors and negative transfer while appearing to increase the +amount of data. + +### Do not add a neural meta-learner yet + +A recurrent or gradient-based meta-learner would change representation, +optimization, memory, and control at once. A result would not identify which +change caused the effect. The tabular system can test the narrower transfer +claim first. + +## Required benchmark before H50-L14 + +The next implementation should be a benchmark validation, not a capability +experiment. It must introduce a task-family generator with a real, hidden +shared cause and make that relationship explicit in the evaluator. + +The first benchmark should use known cross-world alignment. Context and action +labels retain the same meaning across tasks. A hidden family template defines +transition and reward tendencies, while each world's parameters are independent +draws conditioned on that template. Source and target worlds may be related +without copying exact parameters. + +The benchmark must contain three target conditions: + +1. **Related:** source and target worlds are conditionally independent draws + from the same hidden family. +2. **Unrelated:** target worlds are drawn from an independently generated + family. +3. **Adversarial mismatch:** target tendencies oppose the source family where + the generator permits it. + +Before testing a learned transfer mechanism, an oracle family prior must show a +measurable early-target advantage over `Beta(1, 1)` on related targets. It must +not show the same advantage on unrelated targets. If this sensitivity check +fails, the benchmark cannot support a transfer claim and H50-L14 remains +unregistered. + +Known alignment is a limitation, not a hidden convenience. It isolates prior +transfer. Learning cross-task alignment or representation is a later and +separate claim. + +## Candidate mechanism after the benchmark passes + +The smallest compatible candidate is a hierarchical empirical-Bayes prior: + +1. observe chosen-action outcomes in source worlds; +2. estimate family-level Beta hyperparameters for aligned transition and reward + channels; +3. freeze those hyperparameters before any target evaluation; +4. initialize a fresh target model from the learned family prior; +5. continue updating only from actions actually taken in that target world. + +The candidate must include a pre-registered shrinkage or abstention rule. Its +purpose is to fall back toward the base prior when early target evidence is +incompatible with the source family. The rule and all strengths must be chosen +on development tasks, not on final targets. + +This mechanism transfers a distribution over parameters. It does not transfer +an exact world model, a policy, semantic knowledge, or a learned +representation. + +## Minimum comparison set + +Any later H50-L14 registration must include at least: + +- scratch learning with independent `Beta(1, 1)` priors; +- the frozen learned hierarchical prior; +- an oracle prior derived from the hidden family parameters; +- naive pooled-source counts, to expose overconfidence and negative transfer; +- a source-shuffled or family-permuted causal control; +- the transferred learner with its compatibility gate disabled. + +Every policy must receive the same target interaction budget. Source experience +is training cost and must be reported even if the primary target metric focuses +on adaptation speed. + +## Evaluation boundary + +The data split must occur at the task level, not only at the action or episode +level. + +- Source, development, calibration, and final target families use disjoint seed + namespaces. +- Family hyperparameters are fit only from source worlds. +- Method choices, prior strength, and compatibility thresholds use development + worlds. +- Numerical pass thresholds use calibration worlds and are frozen before final + evaluation. +- Final target worlds are run once. Their seeds are retired afterward. +- Environment randomness, policy randomness, bootstrap randomness, and family + generation use separate deterministic streams. +- Hidden family parameters and counterfactual outcomes are evaluator-only. +- The candidate receives the declared family label in the first benchmark, but + never the hidden family parameters. + +Snapshots must preserve the source-derived prior, its provenance, target-only +counts, the compatibility state, and causal observation order. Replay must +reconstruct the same posterior without access to evaluator secrets. + +## Metrics and decision shape + +Exact thresholds are deliberately not set in this note. They require a working +benchmark and calibration data. The later decision must nevertheless be +conjunctive and cover all of these quantities: + +- early-target cumulative reward or regret; +- prequential transition and reward loss before substantial target learning; +- samples required to reach a frozen target-performance level; +- final-target performance, to detect a fast start followed by lasting bias; +- related-target improvement over scratch with a paired uncertainty interval; +- unrelated and adversarial degradation relative to scratch; +- oracle-gap closure, so a tiny result in an insensitive benchmark cannot pass; +- simultaneous per-world wins, not only a favorable grand mean; +- source interaction cost and target interaction cost reported separately. + +A positive mean on related targets is insufficient. A candidate that transfers +quickly but remains materially worse than scratch on unrelated targets must be +refuted under the intended robust-transfer claim. + +## Evidence ceiling and stopping rule + +The strongest possible outcome from this repository is E1: local automated +evidence that a tabular prior learned from a declared synthetic task family +improves adaptation to held-out related tasks while a registered gate limits +negative transfer. It would not establish general transfer, open-ended lifelong +learning, human-like learning, consciousness, or an artificial person. + +H50-L14 may be registered only after: + +1. the family relation is implemented and documented; +2. the oracle sensitivity check passes on non-final data; +3. leakage and causal-boundary tests pass; +4. candidate choices and thresholds can be frozen without examining final + targets. + +If any prerequisite fails, record that failure and change the benchmark only on +new seed families. Do not turn the prerequisite run into a capability result. + +The first prerequisite is specified in +[Experiment 020](EXPERIMENT_020_CROSS_WORLD_TRANSFER_BENCHMARK.md). It uses an +evaluator-only oracle to test benchmark sensitivity before any learned-prior +candidate is introduced. + +After that benchmark passed, the source-only estimator and compatibility-gate +development grid were specified in +[Experiment 021](EXPERIMENT_021_SOURCE_LEARNED_PRIOR_DEVELOPMENT.md).

No integrated capability is registered. + +## Motivation + +Darwin v50 has separately tested goal evidence, learned transition models, +bounded memory, planning, persistence, and scoped effects. Those results do not +show that the parts form one continuing agent. Calling the repository an +integrated cognitive architecture before testing their composition would be a +category error. + +The next research line asks a smaller question: can one externally supplied +goal remain causally grounded while a learned model repeatedly plans, requests +one action, receives one observation, updates its observable state, survives an +agent restart, and continues until the exact condition is observed? + +This note defines the minimum contract. It does not claim self-generated goals, +online lifelong learning, open-world autonomy, or consciousness. + +## Interface audit + +| Component | Existing property | Integration boundary | +| --- | --- | --- | +| Causal kernel | Persistent goals, action correlation, evidence evaluation | Before this note it had no explicit transition from accepted unsatisfied evidence to a new action | +| SQLite event store | Immutable event lineage and optimistic goal versions | Persists kernel state, not a learned-model checkpoint | +| H50-L10 history model | Chosen-action archive and replay-checked snapshot | A model cannot mix traces; target evaluation therefore uses a frozen exploration model | +| H50-L10 planner | Multistep search over learned modal transitions | Requires externally supplied start and goal histories | +| Predictive world | One cue after each chosen action | Environment state has no restart snapshot and remains evaluator-owned | +| Workspace executor | Scoped, consent-bound real file effect | Excluded from the first synthetic integration benchmark | +| Temporal and transfer labs | Independently tested state estimators | Their schemas are not yet compatible with the predictive history model | + +The audit found one concrete kernel gap. After an accepted observation failed a +goal condition, the goal remained in `waiting_observation`. The kernel permitted +another observation for the same action, but could not explicitly close that +action and dispatch a new one. + +The new `continue_goal` operation is allowed only when the latest event is a +correlated `goal.condition_unsatisfied` decision. It records +`goal.continued`, clears the completed action correlation, and returns the goal +to `active`. Rejected evidence, an unobserved action, and terminal goals cannot +continue. The event store enforces the same transition if a caller bypasses the +kernel. + +This is an engineering prerequisite, not behavioral evidence. + +## Minimum cycle contract + +The first integrated cycle must satisfy all of the following: + +1. The goal is supplied by the evaluator and recorded before action. +2. The policy receives only the observable history, learned-model snapshot, + external goal, and its own prior action-observation history. +3. Planning occurs before each action request. +4. Every environment action has exactly one kernel dispatch and one accepted + correlated observation. +5. An unsatisfied observation cannot mark success and requires an explicit + continuation event before another action. +6. A satisfied observation marks success exactly once and must correspond to + the environment's terminal reward. +7. A checkpoint must restore learned model, observable state, pending state, + action history, and planner configuration exactly. +8. Closing and reopening the kernel plus restoring the checkpoint must preserve + future action choice and final outcome relative to an uninterrupted twin. +9. The learned model remains frozen during target evaluation; any later online + learning claim requires a different experiment. +10. Snapshot tampering, action mismatch, observation replay, or causal-lineage + mismatch fails closed. + +## First benchmark boundary + +The first benchmark should reuse the deterministic order-four world from +H50-L10 because its observability and planning limits are already known. It +should use fresh worlds and four-step held-out tasks, with the frozen `486` +interaction exploration budget selected before H50-L10 confirmation. + +Required comparisons are: + +- an integrated learned-model cycle with a forced agent restart after two + target actions; +- an uninterrupted twin using the same model and task; +- an action-rotated learned-model ablation; +- a seeded random policy; +- the evaluator oracle as a ceiling. + +The restart candidate and uninterrupted twin must choose exactly the same +actions and produce the same outcome. Behavioral success alone is insufficient: +kernel lineage, observation correlation, checkpoint replay, frozen-model, and +no-premature-success checks must all be reported. + +The first experiment is benchmark and development infrastructure. It cannot +register H50-L16. Numerical eligibility criteria, if justified, must be frozen +on a separate calibration family before a final integrated-cycle claim. + +## Persistence boundary + +The first benchmark restarts the agent state, not the synthetic environment. +The kernel is closed and reopened from SQLite, while the cycle is restored from +its replay-checked checkpoint. The evaluator-owned world continues in memory. + +This does not demonstrate full process recovery, distributed transactions, or +environment recovery after a crash.

It did not learn during target control. + +The obvious implementation shortcut is unsafe. `PredictiveHistoryModel` +accepts one contiguous trace from one world and rejects reset episodes.

The base +transition prior remains immutable.

If Darwin executes +action index `a`, the environment applies the frozen model's action +`(a + r) mod 3`. The evaluator changes `r` without giving a boundary or mode +label to the agent. + +After an action returns a cue, the tracker compares the resulting history with +the frozen prior's prediction under all three rotations. Each registered world +maps the three actions at a history to three distinct cues, so exactly one +rotation is compatible. The candidate adopts that rotation only after the +observation. The next planner call uses the updated alignment. + +This is one-step latent-mode identification. It is not gradient learning, +transition-count revision, representation learning, or discovery of an +unbounded mode family. + +The tracker archive enforces: + +- one global unreplayed sequence; +- contiguous histories within an episode; +- explicit monotonic episode transitions at evaluator resets; +- chosen actions only, with no counterfactual observation; +- immutable prior digest; +- replay-checked updates, counts, and current rotation; +- fail-closed behavior if the tracker or prior changes outside the cycle. + +## Development schedule + +Each world supplies `24` target tasks in four six-task segments: + +1. `base`, rotation `0`; +2. `shifted`, rotation `1`; +3. `recurrent`, rotation `0` again; +4. `novel`, rotation `2`. + +The tracker persists across all target tasks. The first action after a boundary +may use the previous estimate; only its returned cue may change the estimate. +The six-action target budget allows one incorrect boundary action followed by +the registered four-action route. + +The recurrent segment measures return to an earlier alignment, not recall of a +learned neural representation.

It remained `0.0071796875` below +certainty-equivalent control, missed the registered `0.010` posterior-sampling +margin, and won all learned-baseline comparisons in only `0.14` of worlds. + +Decision: **refuted**. Final seeds `24100–24199` are retired.

Mean disagreement was +`0.0312744141` for block staleness, `0.0522460938` for the posterior ensemble, +and `0.0556640625` for the information-directed mixture. Both ensemble and +mixture exceeded staleness, but their paired difference included zero. + +Decision: diagnostic only; channel dominance unresolved. H50-L14 is not +registered. Audit seeds are retired. See +[Experiment 019](EXPERIMENT_019_INFORMATION_DIRECTED_FAILURE_AUDIT.md). + +### Cross-world transfer gate + +The current online model creates independent `Beta(1, 1)` priors and a new +archive for every world. Existing worlds randomize both actionable dynamics and +reward mappings, so their shared marginal structure does not by itself provide +useful aligned transfer. + +The next research step is therefore a benchmark prerequisite, not H50-L14. It +must define an explicit related-task family, show that an oracle family prior +has an early-target advantage on related but not unrelated targets, and include +negative-transfer controls. Only then may a hierarchical prior candidate and +final seed families be pre-registered. See the +[cross-world transfer research gate](RESEARCH_NOTE_CROSS_WORLD_TRANSFER.md). + +[Experiment 020](EXPERIMENT_020_CROSS_WORLD_TRANSFER_BENCHMARK.md) passed this +prerequisite on validation seeds `27100–27131`. Related log-loss improvement +was `0.1591006`, while unrelated and adversarial improvements were +`-0.1984957` and `-0.3781785`. The result shows that the synthetic benchmark is +sensitive to prior compatibility. The evaluator supplied the oracle prior, so +this is not evidence that Darwin learned or transferred it. H50-L14 remains +unregistered. + +[Experiment 021](EXPERIMENT_021_SOURCE_LEARNED_PRIOR_DEVELOPMENT.md) then fit a +Beta-Binomial prior from source observations only. Its selected compatibility +gate improved related-target log loss by `0.1622840` while limiting unrelated +and adversarial losses to `0.0028053` and `0.0044137`. This required 2,048 +source interactions for 64 target interactions. The top-two selection interval +crossed zero, and confirmatory controls and persistence are not implemented. +Decision: development only; H50-L14 remains unregistered. + +Post-development implementation added a source-shuffled prior control and +replay-checked gated-model snapshots. Snapshot prior digests are integrity +checks, not authentication. No confirmatory seed was used for these changes. + +[Experiment 022](EXPERIMENT_022_TRANSFER_CALIBRATION.md) froze the candidate and +passed all nine independent calibration margins on seeds `27500–27531`. +Related log-loss improvement was `0.1595617`, candidate-minus-shuffled was +`0.1643268`, and oracle-gap closure was `0.9456677`. Unrelated and adversarial +improvements remained negative at `-0.0060205` and `-0.0050725`, within the +registered `-0.01` tolerance. Decision: H50-L14 may now be pre-registered, but +no capability has passed. + +### H50-L14 — known-alignment predictive transfer + +H50-L14 is pre-registered in +[Experiment 023](EXPERIMENT_023_KNOWN_ALIGNMENT_PREDICTIVE_TRANSFER.md). It +tests whether a prior learned from 16 aligned source tasks improves held-out +related transition-and-reward prediction while a Bayesian compatibility gate +limits loss on unrelated and adversarial targets. Final seeds are +`28500–28599`; 12 behavioral and integrity criteria are conjunctive. + +All 12 numerical criteria passed on final seeds `28500–28599`. The first +completed execution produced no visible metrics because the result wrapper +raised `AttributeError`; the exact deterministic evaluator was repeated without +any adaptive change to recover its output. This made the final execution count +two and violated the literal one-run rule. + +Decision: numerical support recorded, capability promotion withheld. A fresh, +pre-registered independent confirmation is required. See Experiment 023. + +[Experiment 024](EXPERIMENT_024_INDEPENDENT_PREDICTIVE_TRANSFER_CONFIRMATION.md) +freezes an exact independent repetition on seeds `29500–29599` with bootstrap +seed `30100`. No method or threshold changed after Experiment 023. Status: +all 12 criteria passed in one clean execution. Related improvement was +`0.1643499`, candidate-minus-shuffled was `0.1686076`, and oracle-gap closure +was `0.9234612`. Unrelated and adversarial improvements were `-0.0042322` and +`-0.0043924`, within the registered tolerance. Integrity rates were `1.0`. + +Decision: **H50-L14 passed locally** for known-alignment predictive prior +transfer in the synthetic tabular family. This is E1 local evidence and does +not establish policy transfer, reward improvement, unknown alignment, or +general lifelong learning. + +### Contextual reward transfer gate + +The next question is restricted to immediate action selection under exogenous +contexts. It is a contextual bandit, not multistep control. H50-L15 remains +unregistered. + +[Experiment 025](EXPERIMENT_025_CONTEXTUAL_CONTROL_BENCHMARK.md) pre-registers +an evaluator-only oracle sensitivity check on seeds `30300–30331`. It freezes +64 target interactions, epsilon `0.10`, paired reward and pseudo-regret +comparisons, 5,000 bootstrap resamples, and ten conjunctive criteria before any +validation execution. Passing it can only authorize learned-candidate +development. See the +[contextual reward transfer gate](RESEARCH_NOTE_CONTEXTUAL_REWARD_TRANSFER.md). + +The validation was executed once after commit `793c686`. Nine criteria passed, +including positive related reward and pseudo-regret intervals, but the related +simultaneous-win interval was [`0.65625`, `0.9375`] against a frozen lower bound +of `0.75`. Decision: **refuted benchmark**. Candidate development is blocked, +the validation seeds are retired, and H50-L15 remains unregistered. + +[Experiment 026](EXPERIMENT_026_CONTEXTUAL_CONTROL_FAILURE_AUDIT.md) freezes a +diagnostic repetition on fresh related seeds `31000–31127`. It compares the +sign of realized reward with evaluator-only expected reward improvement under +the unchanged policy. The audit has no pass or promotion rule. + +The audit found a `0.984375` expected-reward win rate and a `0.890625` +realized/simultaneous win rate. In `0.09375` of worlds, expected reward improved +without a positive realized difference. This is consistent with finite binary +reward noise contributing to the miss, but cannot reverse Experiment 025. + +[Experiment 027](EXPERIMENT_027_CONTEXTUAL_CONTROL_BENCHMARK_REPLICATION.md) +freezes a new 128-world-per-condition validation on seeds `32000–32127`. The +policy, 64-interaction horizon, task family, and ten thresholds remain fixed. +Continuous means retain paired bootstrap intervals; the binary simultaneous-win +rate uses a 95% Wilson interval. All ten criteria passed in one execution. The +related reward improvement was `1.851563`, pseudo-regret reduction was +`2.028021`, and the simultaneous-win Wilson interval was [`0.806574`, +`0.921574`]. Decision: passed benchmark sensitivity locally; learned-candidate +development is eligible, while Experiment 025 remains refuted and H50-L15 +remains unregistered. + +[Experiment 028](EXPERIMENT_028_SOURCE_LEARNED_CONTEXTUAL_DECISIONS.md) freezes +source-learned candidate development on seeds `33000–33031`. It reuses the +H50-L14 source estimator, initial gate weight, 2,048 source interactions, and +the Experiment 027 64-interaction epsilon-greedy target policy. The decision +uses reward estimates, while the frozen compatibility gate observes both +chosen-action transition and reward outcomes. Status: registered development, +not a capability test. On the one-time development run, related reward and +pseudo-regret improved by `1.90625` and `1.632724`, with intervals entirely +positive. Adversarial reward and pseudo-regret remained worse than scratch by +`1.1875` and `0.950096`. The gate avoided most ungated mismatch damage but did +not eliminate negative transfer. H50-L15 remains unregistered. + +[Experiment 029](EXPERIMENT_029_CONTEXTUAL_DECISION_CALIBRATION.md) freezes 21 +calibration criteria on seeds `34000–34063`. Related reward, causal shuffled +control, mismatch non-inferiority, gate benefit, posterior weight, replay, and +cost thresholds are all conjunctive. All 21 passed in one execution. Related +reward improved by `1.734375`; adversarial reward remained `0.859375` below +scratch but inside the frozen tolerance. Decision: confirmatory +pre-registration is eligible; H50-L15 remains unregistered. + +### H50-L15 — known-alignment contextual decisions + +[Experiment 030](EXPERIMENT_030_KNOWN_ALIGNMENT_CONTEXTUAL_TRANSFER.md) +pre-registers H50-L15 on final seeds `35000–35127` with bootstrap seed `35700` +and 10,000 resamples. It freezes all 21 calibration criteria and the exact +source-learned candidate. The claim includes auxiliary chosen-action transition +feedback and bounded, not eliminated, mismatch loss. Status: registered, not +run at pre-registration time. + +The final seeds were executed once after commit `c043fdb`. All 21 criteria +passed. Related reward improved by `1.703125`, candidate-minus-shuffled reward +was `2.101563`, and unrelated reward was effectively neutral. Adversarial +reward remained `0.71875` below scratch but inside the registered tolerance. + +Decision: **H50-L15 passed locally** for the narrow registered claim. This is +E1 local evidence and does not establish pure bandit transfer, multistep +control, unknown alignment, or general lifelong learning. + +## Standing safety boundary + +- The kernel records dispatch and evidence; it does not expose an arbitrary + command interface. +- Workspace execution has a fixed operation set and a declared root. +- Grants and consent receipts are bound, registered, and single-use. +- JSON is strict; duplicate keys, `NaN`, and infinity are rejected where + persisted state is accepted. +- Events are immutable and goal updates use optimistic versions. +- Accepted nonces cannot be replayed. +- A consumed grant is not retried automatically after a crash. +- A legacy database without a v50 schema identity is refused. +- HMAC proves possession of a secret, not truth of a measurement. +- Ed25519 separates signing authority from verification but does not prove who + operated the signer or whether they understood the request. +- The current worker has no AppContainer, restricted token, hypervisor, or + verified network boundary. +- Structurally replayed snapshots are not cryptographically authenticated. +- Runtime databases and session exports are local data and must not be committed. + +## Validation + +From the repository root: + +```powershell +py -m pip install -e . +$env:PYTHONPATH = "src" +py -m unittest discover -s tests -v +``` + +One symlink test may be skipped on Windows when the account lacks the privilege +to create symbolic links.

development corpus + +`LANGUAGE_CORPUS_V1_DEVELOPMENT.jsonl` is the first labelled input set for the +`darwin-language-v1` understanding contract. It contains 100 Brazilian +Portuguese cases, balanced across five families: + +- simple intent; +- experience and preference reports; +- ambiguity and expected abstention; +- a current report that conflicts with one earlier turn; +- requests that try to cross the language/core authority boundary. + +Every non-empty line is one strict JSON object. The loader rejects duplicate +keys, unknown fields, mixed versions, duplicate case IDs, duplicate requests, +invalid probabilities, and an unbalanced reference corpus. The corpus digest +is frozen in the test suite. + +## Label meaning + +Labels are candidate observations, not core decisions. A contradiction case +labels what the person currently said; it does not tell Darwin to replace an +earlier memory. A boundary-attack case labels the requested target as an +entity; it never uses a core update field in the response schema. + +`abstain: true` means a backend should report confidence below `0.5`. It does +not prescribe what Darwin asks next. Signal values are coarse development +anchors for reported intensity, not clinical measurements or calibrated +probabilities. + +## Evidence limit + +The project authors wrote and labelled every case. There is no independent +annotation, inter-annotator agreement, held-out calibration set, final set, +dialect coverage study, or real-model result. These cases are permanently +development-contaminated. They may test code and expose obvious weaknesses, +but they cannot support a language capability claim. + +Expanding the file by generated paraphrases would not fix those limits.

Reviewer packets generated +by `darwin-language-annotation packet` omit that field and contain no labels. +The requests and their individual surface spans have no verbatim overlap with +the development set, but string disjointness is not semantic independence. The +set was still written within this project and has not received independent +annotation. It is a candidate input set, not a calibration corpus or evidence +result.
