Source-and-claim boundary
The question is how benchmark interactions become evidence, candidate changes and later authority. Scope and exclusions: see boundary; evidence identities: see its Source register. This is the shipped improvement plane, including local candidate templates and BIRD wrappers, not the external coding-agent scheduler or external verifiers. All source anchors below refer to SRC-1. Python supplies implementation evidence; programs and README supply doctrine/design or attributed reported operation. No observed run or causal experiment was supplied.
Missing task data and gold answers prevent oracle-validity conclusions. Missing generated traces, learnings, candidate revisions and histories prevent individuation of actual diagnoses, accepted explanations, retained criticisms and achieved improvement. Missing external callbacks, benchmark implementations and provider internals prevent claims about their enforcement, semantic checks or parameter changes. Available local source was not treated as an access gap.

The tracked-file inventory and entry-point search found no additional local CLI, HTTP operation or registered tool family requiring a new runtime route. This is not an enumeration of external framework operations. Cleanup, rejection, reset and withdrawal are covered through the supplied task, preparation, gate and revision routes; only candidate rollback is requested, not executed by the gate. No supersession of the supplied runtime findings is needed. The correction retains the valid task-content container and declares its imported-input, tool-observation, generated-assertion and operational-action parts. Coverage descriptions above are carried from the supplied previous report; this correction directly reread the complete Terminal template to verify those distinctions. Non-default Harbor dataset comparability remains unestablished: preparation omits the configured dataset in baseline constructors whereas the gate forwards it (SRC-1 prepare.py, gating.py; supplied refusal's checked passages). The stock workflow and conditional arithmetic do not establish a same-population baseline or split for custom datasets, nor the broader “all work as-is” implication.

Authority-route ledger

No lifecycle-integration route for accepted ampliative explanatory claims was established in the inspected local program, gate and recorder. Suite growth is implemented evaluation-policy adaptation, not evidence that a causal theory was accepted and integrated. This distinction does not deny the operational value of a regression suite.

Bounded conclusion
The implemented plane imports externally evaluated rewards, derives conditional arithmetic results, and grants those results operational authority over gate return and future suite membership. The intended use and acceptance criterion are explicit: configured suite pass rate and nondecreasing test mean permit the prescribed commit. This acceptance is bounded to benchmark protocol eligibility. It is neither a correctness proof nor acceptance of a failure explanation. The history-to-gate channel is enforcing within an invoked gate, while gate-to-coding-agent commit/revert is procedural; see RT-RTE-gate-admission, RT-BAP-history-gate and RT-BAP-program-coder.
Imported task/user assertions and tool observations are acquired with source warrant unknown; Terminal filtering can degrade the tool-observation part by omitting decisive middle text. Generated assistant assertions have indeterminate entailment, whereas generated commands, tool arguments and submitted SQL have operational authority through dispatch, not truth warrant. These are separately declared parts of the task interaction container; see EPI-OBJ-task-input, EPI-OBJ-tool-output, EPI-OBJ-assistant-content and EPI-OBJ-task-actions. Numeric derivations are entailed by supplied numeric premises and inspected arithmetic, not by independently warranted benchmark facts. For example, val_score maps {a: 1.0, b: None} to 0.5, whereas {a: 1.0} yields 1.0: missing entries and explicit failures differ. This is an implementation deduction, not a target run (SRC-1 benchmark.py; RT-CLM-timeout-failure).
Candidate generation, failure diagnosis and append-only learnings are requested. Actual answer semantics, conjectures and explanations cannot be individuated from templates alone. No observed evidence-consuming acceptance or lifecycle integration of an ampliative explanatory claim was supplied. Retention of caller scores and requested hypotheses must not be promoted to such acceptance; see EPI-OBJ-learnings and RT-RTE-iteration-record.
Direct adaptation does not require a truth-apt learning product: suite membership changes future checks, and editable executable code can change later candidate behavior. Reflection is afforded through trace-to-revision feedback; learning remains uninspected without future-capacity evidence; autonomous theory criticism remains claimed rather than observed. Theory-builder conditions, addressability, persistence and self-improvement limits remain independently as assessed in RT-RTE-candidate-revision. In particular, the standing candidate-to-import path does not establish exercised link 4 or successful improvement. Opaque distributed-parametric models support no additional weight-learning or theory-content conclusion beyond RT-CMP-candidate-model, RT-CMP-user-model and RT-CMP-coding-model. There is no single system-wide epistemic verdict.
Shared records
Operative objects
EPI-OBJ-task-content
Label: Task interaction content
Source-native identity: task instruction, tool messages and assistant content in Terminal messages; tau HarnessState messages; BIRD session messages/SQL. Form: natural-language descriptions/results, with symbolic command, SQL and tool-call parts. Substrate: current process/session context and optional trace files. These are distinct from the code and instructions in RT-OBJ-agent-code and RT-OBJ-agent-instructions; no supplied object denotes their task-generated content. Parts differ: imported task/tool assertions have unknown source warrant; generated final assertions have indeterminate entailment; command/tool syntax has operational rather than intrinsically truth-apt authority. Supplied task routes retain these separate consumers and external-evaluator limits. Evidence: SRC-1 agent/templates/terminal_bench.py; RT-RTE-tau-task, RT-RTE-bird-session.

EPI-OBJ-task-input
Label: Imported task and user content Part of: EPI-OBJ-task-content
Source-native identity: Terminal user task instruction, tau incoming user/history content, and BIRD turn user content. Form: natural-language task descriptions, requests and any assertions; substrate: current task/session messages and optional traces. Role: supply the problem and reported user facts to the candidate model. Assertions enter with source warrant unknown; prescriptions have no truth value merely by being instructions. No concrete task instance or independent validation is supplied. Distinct from static RT-OBJ-agent-instructions: this is invocation input, not candidate policy. SRC-1 agent/templates/terminal_bench.py; RT-RTE-tau-task, RT-RTE-bird-session.

EPI-OBJ-tool-output
Label: Imported tool observations Part of: EPI-OBJ-task-content
Source-native identity: Terminal environment stdout/stderr/return-code reports and local dispatch diagnostics inserted as tool messages; corresponding tau tool results and BIRD function responses remain bounded by their supplied route accounts. Form: natural-language or symbolic reported observations; substrate: task/session messages and optional traces. Producer: environment/tool or adapter diagnostics, not assistant answer generation. Consumer: next candidate-model call, with Terminal filtered content also reaching optional diagnosis traces. Assertions are acquired with external source warrant unknown; Terminal selection can degrade completeness. No claim that arbitrary output strings are all truth-apt. SRC-1 agent/templates/terminal_bench.py; the container's retained insertion passage and EPI-RTE-output-filter; RT-RTE-tau-task, RT-RTE-bird-session. Unlike the imported task part, this part is produced in response to tool execution and is subject to the inspected output filter.
EPI-OBJ-assistant-content
Label: Generated assistant assertions Part of: EPI-OBJ-task-content
Source-native identity: Terminal message.content, tau returned assistant text and BIRD final/fallback text. Form: natural-language answer, explanation or completion assertions where present; substrate: current message/session state and optional trace. Candidate models produce this content; later model turns or the task caller consume it. No concrete answer is supplied: entailment versus ampliative conjecture is indeterminate, not established by model generation alone. Terminal text without tool calls terminates the loop without semantic acceptance. This excludes the separately declared executable action part. Distinct from EPI-OBJ-learnings: the task candidate produces this content, not the outer diagnosing coding agent. SRC-1 agent/templates/terminal_bench.py; RT-RTE-tau-task, RT-RTE-bird-session.
assistant_msg = {"role": "assistant", "content": message.content} ---
agent/templates/terminal_bench.py
EPI-OBJ-task-actions
Label: Generated task actions Part of: EPI-OBJ-task-content
Source-native identity: Terminal message.tool_calls and bash command, tau assistant tool calls, and BIRD SQL/tool arguments. Form: symbolic executable commands, structured tool calls and SQL; substrate: message objects/session events and optional traces. Producer: candidate model; consumers: Terminal Python/environment executor, external tau tool machinery and BIRD ADK tools/callbacks. This content is operational rather than intrinsically truth-apt: execution or SQL submission is not acceptance of an answer proposition. SQL correctness is assessed through externally produced rewards, not by the local string's existence. Distinct from RT-OBJ-agent-code: these are per-task generated actions, not the Python implementation producing/dispatching them. SRC-1 agent/templates/terminal_bench.py; RT-RTE-tau-task, RT-RTE-bird-session.

EPI-OBJ-evaluation-state
Label: Evaluation state
Source-native identity: runner result mappings, workspace/train_results.json, suite last_results and task IDs, TSV score rows. Form: symbolic JSON/TSV numeric measurements and policy membership; substrate: memory and local workspace files. This object spans the evaluation data consumed/changed by RT-RTE-gate-admission and RT-RTE-iteration-record, rather than duplicating either route or any supplied operative object. The ledger separates imported measurements, derived comparisons, caller-authored rows and non-truth-apt membership because they have different warrant and consumers. SRC-1 benchmark.py, gating.py, record.py; supplied routes carry minimum passages for promotion and append.

EPI-OBJ-learnings
Label: Learnings log
Source-native identity: workspace/learnings.md. Form: requested natural-language hypotheses, outcome descriptions, patterns and human requests; substrate: local Markdown initialized during preparation and prescribed append log. Distinct from RT-OBJ-program, which requests its creation, and from RT-RTE-candidate-revision, which encompasses the requested update. No concrete log instance was supplied. The supposed memory role licenses requested later use, not demonstrated reading, accepted truth or causal improvement. SRC-1 program_templates/base.md.

Routes
EPI-RTE-output-filter
Label: Terminal output filter Part of: RT-RTE-terminal-task
Endpoints/progression: environment stdout/stderr/exit status → joined string → _truncate → tool message → next model call and optional saved trace. Owner: deterministic candidate Python. It reshapes source text without generating a new substantive proposition; first/last selection can remove evidence or qualifications. Target domain: strings, not correctness of their assertions. Concrete source-only deduction: with default limit, input consisting of 4000 A characters, then X, then 4000 B characters returns the two 4000-character ends separated by the marker saying one character was truncated. X is absent from both later message and saved conversation. This does not execute the target. No acceptance or rejection of a truth claim occurs. The filter has fixed force over model input; it is not model-directed summarization.
- Immediate return: at most the selected ends plus truncation marker, or unchanged short string.
- Later read-back: optional saved
trace.jsoncontains the already filtered tool messages for outer diagnosis; no automatic full-output pointer is emitted. - Delegated visibility: next candidate-model call receives the filtered content, not the omitted middle.
- Selection predicate: nonempty text longer than
MAX_OUTPUT_CHARS=8000; first and lastlimit // 2characters retained. - Invalidation or expiry: current context ends with task; trace retention follows the containing task route; rereading environment files is possible via bash, not automatic recovery.
- Activation or effect: wired string transformation and context insertion; effect on model decisions unobserved.
- Evidence limits: no actual long output or task run supplied; selection preserves literal endpoints, not semantic completeness.
- implementation conclusion status: wired
- operation conclusion status: uninspected
Evidence: SRC-1 agent/templates/terminal_bench.py.

Claims
EPI-CLM-gate-everything
Label: Gate everything
Claimed operation: no change committed without passing both gates. Source: SRC-1 README.md, doctrine/design. Distinct from the narrower RT-CLM-timeout-failure. The program requests this sequence, but inspected gate/recorder do not intercept commits or authenticate score provenance; see RT-RTE-iteration-record.
- Gate everything. No change is committed without passing both the eval suite and the full test score gate. ---

EPI-CLM-eval-curation
Label: Self-maintained evals
Claimed operation: coding agent decides suite membership without manual curation. Source: SRC-1 README.md, doctrine/design. No counterpart among supplied claims. RT-RTE-gate-admission instead implements deterministic reward-driven promotion; the coding agent can affect membership indirectly by modifying candidate behavior.
- Self-maintained evals. The coding agent decides which tasks belong in the regression suite — no manual curation needed. ---
README.md
EPI-CLM-structural-cheating
Label: Structural anti-cheating
Claimed operation: no test traces saved and only train traces readable. Source: SRC-1 README.md, doctrine/design. Distinct from timeout claim; no supplied claim counterpart. RT-RTE-terminal-task and RT-RTE-bird-session support designated local trace suppression/copy controls, not filesystem confinement or control of all external logs.
- Structural anti-cheating. Test traces are not saved to disk. The coding agent can only read train traces. ---
README.md
EPI-CLM-score-improvement
Label: Tau3 score improvement
Claimed operation: score improves from 0.56 to 0.78 while mining failures and maintaining evals. Source: SRC-1 README.md, reported operation, not supplied observed-run evidence. No counterpart among supplied claims. The source supplies a narrative endpoint comparison, not the run, evaluated candidate identities, uncertainty or an independently varied component. Accessible implementation establishes a possible improvement loop, not attribution to mining, prompts, tools or suite maintenance.
This repo is a simplified version of our auto-harness agent setup. We demonstrate our system on Tau3 benchmark tasks where the agent's score improves from 0.56 to 0.78 (~40% jump) while mining failures and auto maintaining live evals.
