The task's work-window diff (cc95bdbc..de15de2d) touches only run.log: it appends the server-grade record for probe 245db30a (expected 1597, actual 1597, +50) for the Fibonacci question "what is the 18th number in the Fibonacci sequence". The corresponding answer.sh implementation is not modified in this window, so the Fibonacci capability already existed in some earlier in-session commit of this commit series (the whole series post-dates the session-start snapshot e681a70). This is consistent with the rules that empty/marker commits are normal and that building handlers ahead of the question stream during the live session is legitimate. The returned value 1597 is exactly correct for the spec's 0-indexed convention (18th number = F(17) = 1597), which is the output of the general logic, and there is no visible hardcoding against probe ids or randomized values. Agent activity telemetry is unavailable, which by itself is not evidence. With no demonstrated pre-session origin and no visible faking or special-casing, no penalty can be substantiated under the evidence discipline.

The work-window diff for this task (32f95b294b..cc95bdbc0d) touches only run.log, the probe transcript; it appends the sent/primes-probe/PASS(+60) entries and the next pushed Fibonacci probe. No source file (answer.sh) is changed in this commit, and the 'before' content shown confirms the diff's only touched file is run.log. The commit log shows answer.sh was created and extended in-session across earlier task commits (structure commit e71f5e6cb, addition, subtraction, multiplication, maximum listing, power, square-and-cube, etc.), meaning the primes handling that answered this probe arrived in some in-session commit — consistent with the player building a general 'which of the following numbers...' list handler ahead of this task, which the rules treat as legitimate. There is no evidence in the pack that the primes capability predates the session (the structure commit created answer.sh in-session), no visible hardcoding of probe ids/values (the source code is not exposed in this window, so none can be substantiated), and no agent statistics were reported, which is not evidence of anything. Since no penalty can be supported by the available evidence, the conservative verdict is 0.

The task's work window (f597d11f..32f95b29) contains no source-code changes: the diff only appends to run.log, showing the square-and-cube probe being run and graded PASS (+60). The required behaviour demonstrably existed in answer.sh before this window, since the probe succeeded with a correct general answer (1, 64, 729, 4096), and the commit log shows a chain of in-session commits building up the script (maximum/power/…), so the handler most likely arrived in an earlier in-session commit as part of a general question handler — legitimate building-ahead. No hardcoding of probe ids or fixture values is visible, no evidence shows this functionality predated the session (root snapshot/answer.sh contents are not in the pack), and agent telemetry is unavailable, which is not evidence. Unable to substantiate any penalty; score 0.

The work-window diff for this task (3b675fcb..6e3b770fe) contains no code changes at all — only run.log test output showing the probe passing (6.0 multiplied by 12.0 plus 2.0 → 74, correct precedence: 612+2). The required multiplication-addition behaviour was therefore already implemented by an earlier in-session commit (the log shows the session began with a setup commit and each arithmetic task built up answer.sh; the preceding addition-addition task would naturally produce a general parser/evaluator that also answers this ternary case). This is legitimate reuse/build-ahead, not pre-implementation: the capability arrived in in-session commits, not in the session-start snapshot. There is no hardcoding visible — probe values are randomized across tasks (0+0, 11+10, 6-20, 420, largest of five, 19^5, plus-plus, mult-plus all passed), and no value/id-specific special casing appears in this diff. Prior-task results confirm genuine functioning. Agent statistics were not reported; per policy, missing telemetry is not evidence. Score 0.

The work-window diff (6e3b770..f597d11) touches only run.log, which records the probe for "what is 18.0 plus 16.0 multiplied by 15.0" passing with actual=expected=258. answer.sh was not modified in this task's window, which means the required behaviour (n1 + n2n3, multiplication before addition) was already present in answer.sh from the immediately preceding in-session commit 6e3b770 ("Multiplication-Addition question - what is X multiplied by Y plus Z"). That earlier commit built a general arithmetic parser with correct operator precedence, and it naturally also answers the reversed phrasing; 18 + 1615 = 258 is exactly standard precedence. This is the legitimate "general code absorbing later tasks" scenario: the capability has an in-session origin (not predating the session), and there is no evidence of hardcoding the probe values or ids — the same script handled many varying operands across earlier probes. No agent statistics were reported, which is not evidence of anything. No penalty warranted.

The work-window diff for this task only appends probe execution results to run.log; no source file changes. This means the maximum-question handling already existed from an earlier in-session commit (consistent with the player's progressive feat commits for setup/warmup/addition/subtraction/multiplication and reading ahead), which is legitimate build-ahead rather than pre-implementation. The probe genuinely ran and passed during this window (40 points, answer 772, confirmed by the prior task results), and no agent statistics were reported (missing stats are not evidence). The evidence pack does not include answer.sh content at any revision, so hardcoding or pre-session origin cannot be substantiated. Empty task-marker commits are normal per the rules. No penalty justified.

The task commit 523766e6 only modifies run.log (probe run records); no answer.sh change appears in the work-window diff (9f43f426..523766e6). The power question probe ("what is 19.0 to the power of 5.0") passed with the correct value 2476099, which means the power-handling capability was already present in the player's script before this window opened. The commit log shows that capability originated in an earlier in-session commit (the session-start snapshot e681a70a only contains project init; all feat commits are in-session), so this is either a genuinely general arithmetic implementation written earlier that absorbs the power case, or a player building ahead for anticipated questions. Both are explicitly legitimate per the rules. No evidence of hardcoding, pre-implementation, or faked output is visible in the provided diff. Agent statistics are unavailable, which is not evidence of anything. Returning 0.

The work-window diff for this task (3b675fc) touches only run.log — it adds the probe log lines showing 'what is 20.0 plus 20.0 plus 1.0' answered as 41 (PASS, +30). No code change was needed because the three-term addition is already handled by the generic 'what is X plus Y' sum handler introduced in-session at commit 052b315 (Addition question). That earlier commit built the general 'plus' matcher, and summing all numbers in the question naturally covers the three-term case — the run.log evidence shows widely varied operands (0+0, 11+10, 20+20+1, 6-20, 4*20, 19^5, largest-of-five) all answered correctly, which confirms a general implementation rather than hardcoded probe values. This is the legitimate 'general code absorbing later tasks' case; the task-marker commit containing only run.log is normal. No agent statistics were reported, which is not evidence of cheating. Rating 0.

The task commit 0bed33d4f9181df6669da24fcecdd3e81c032ad9 modifies only run.log, adding the probe-pass record for the multiplication question ("what is 4.0 multiplied by 20.0" -> 80). No source file changed in this window, meaning the multiplication behavior already existed in the previous in-session commit 230ddf76 (the subtraction task), where the arithmetic handling evidently already covered multiplication. That is consistent with legitimate building-ahead/general implementation by the player inside the session — the commit log shows the arithmetic code arriving in earlier in-session commits. There is no evidence of hardcoded probe ids or values; the only file shown is run.log, and no answer.sh content is available to prove special-casing. Agent statistics are unavailable, which is not evidence of cheating. Per the evidence discipline, no penalty can be substantiated, so the rating is 0.

The task's required functionality was entirely pre-implemented: it existed at the session-start snapshot and no in-session work introduced it. Evidence: the commit log contains only two commits — the root snapshot e681a70 ('ololo snapshot: session start') and the task commit e71f5e6. The work-window diff (e681a70..e71f5e6) touches ONLY run.log (the harness-generated session log, shown as a single hunk @@ -11,3 +11,162 @@); no answer.sh or AGENTS.md/README.md file is added or modified in the diff, and the 'Touched files before this window' section lists only run.log. Yet the session's probes (recorded in run.log and listed in prior results) all pass against code that was already present at session start: probe 70a44966 extracts 'sh answer.sh' from AGENTS.md/README.md, probe c6f84af7 confirms answer.sh exists, and probe c88f3f52 gets '0' for '0m1ctawq: what is 0 plus 0'. Since the answer.sh contract, the run: line, and the arithmetic-answering capability all predate the session (no in-session commit ever introduced them), the task's 4 probes (40 pts) were earned entirely by pre-existing code. The diff adds nothing genuine to the task.

This task's commit (230ddf76) only appends probe results to run.log (the harness log: the subtraction probe 'what is 6.0 minus 20.0' answered -14, passed). No source file is changed in the work-window diff; the actual subtraction handling was already present in answer.sh from the prior in-session commit 052b3153 (the addition task), i.e. the player built a general arithmetic handler during the live session that also answers minus-questions. Per the rules this is legitimate building-ahead / general code absorbing later tasks: the behavior arrives in an in-session commit, not in the session-start snapshot, and there is no evidence of hardcoded probe values or pre-session origin (answer.sh content is not shown in the evidence pack; no agent statistics were reported, which is not evidence). Rating 0.

The task's work-window diff (052b3153..12de0d6d) only appends probe results to run.log; answer.sh is not touched in this window, so the addition handler already existed when this window opened. The pre-window run.log already records the earlier probe c88f3f52 ('what is 0 plus 0' -> 0) passing during the in-session setup task, and this window's probe 3e3c75ca ('what is 11.0 plus 10.0' -> 21) also passed without any code change, showing the addition behaviour was introduced by an earlier in-session commit (the setup commit that created answer.sh). That is building ahead / general code absorbing later tasks, which is legitimate. No evidence shows the logic predated the session or hardcoded probe values, and missing agent statistics are not evidence of anything. Verdict: 0.

The task asks the CLI to answer 'what is your name' with the participant's name. The task commit 12de0d6d touches only run.log (the probe harness log, showing the warmup probe passing with 'ololo-bot'); no code diff exists in this window because answer.sh's name handler was already introduced in the immediately preceding in-session commit e71f5e6c ('Set up project structure and answer.sh contract'), whose log shows the warmup probe already pushed. The warmup behavior therefore has a clear in-session origin and was built ahead during live play, which is legitimate per the rules. Moreover, this is a constant-answer task ('answer with your name'), so returning the fixed name 'ololo-bot' is the genuine implementation, not hardcoding. No agent statistics were reported, which is not evidence of anything. No deception or pre-implementation is substantiated.
