Run 28505792149 — 2026-07-01T09:04:41Z

Window: 24h ending ~2026-07-01T08:58Z. 58 completed tend runs (28 token-bearing in the report; the rest skipped ci-fix-on-green / mention-dispatch no-ops). 0 failed / cancelled / timed-out runs in the window. Spend: $47.59 API-list cost (186.6K in / 247.9K out / 1.76M cache-create / 32.6M cache-read) across 541 turns. Per-workflow: tend-review $18.60 (9 runs / 180 turns), tend-mention $10.15 (13 / 157), tend-nightly $6.99 (1 / 57), tend-notifications $6.59 (6 substantive / 76), tend-triage $5.26 (1 / 71). A quiet, low-volume day (prior windows ran $90–140 on 130+ runs); no cost outlier — the highest single run is the nightly at $6.99.

Long-running / near-timeout jobs: none near-timeout (default 360-min cap; 90% = 324 min). Longest jobs: tend-nightly 28502073382 32 min (success, full sweep — see below), tend-review 28491671108 28 min (mostly clean CI-poll waiting on a dependabot bump), tend-triage 28498141748 22 min. None hit the 3600s session cap.

Outcomes — healthy:

• 1 bot PR merged: #3344 (fix: preserve subdirectory position on wt remove, from triage of issue #3343).
• 3 bot PRs opened this window, awaiting maintainer: #3346 (mention-driven refactor: unify subdir preservation for wt step relocate), #3347 (nightly: readme month → July 2026), #3348 (nightly: drop misleading mutual-exclusivity tests).
• 0 bot PRs closed-without-merge → no maintainer corrections this window. 0 bot issues opened/closed.

Findings (passing gates): none

A clean, quiet 24h. Every substantive decision aligned with running-tend / running-in-ci: triage repro'd and shipped a merged fix; the heaviest review ($5.13, 28499027341 on #3329) did full grounded verification, spawned two correctness/removed-behavior finder subagents, self-corrected a review-API line-number mismatch (merged-tree L35 → head-commit L19) and posted a single well-anchored inline suggestion; the two heaviest mention runs both shipped their deliverables with no stranded work.

Below-threshold observations (no action)

Observation #1: notifications run gave an exemplary "don't ship what you can't verify" Windows diagnosis

• Evidence level: Confirmatory (healthy behavior, 1 occurrence).
• Run: tend-notifications 28504645987 ($2.58 / 27 turns / 29K output — ~5× the typical notifications cost, but all substantive). Session 8a6438f3-0e6b-4b0a-82cb-3cbbc53a997d.jsonl.
• Detail: PR #3346's new test_relocate_preserves_subdir fails only on test (windows) (required) — git worktree move returns "Permission denied" when the wt process CWD is inside the moving tree, a Windows directory-rename lock the Linux sandbox can't reproduce. The run traced the root cause through relocate.rs / directives.rs (contrasting why git worktree remove tolerates a live CWD but move doesn't), then flagged it as a design question rather than shipping an unverifiable fix — exactly the running-tend "Don't ship fixes you can't verify" rule. SHA-pinned, owner-scanned, deduped before posting. Positive baseline.

Observation #2: cargo-discovery probe recurred in nightly — but milder (2nd occurrence, efficient)

• Evidence level: Low (nitpick; 2 occurrences total, this one efficient). Structural (cargo isn't on the sandbox default PATH, so a nightly step needing it must locate it) but negligible waste now.
• Run: tend-nightly 28502073382. Session log has a single combined probe (ls ~/.cargo/bin/cargo …; command -v rustup; which cargo …; ls ~/.cargo/env) that resolved cargo's location in one Bash call.
• Detail: The 2026-06-29 entry recorded a "cargo discovery dance" (several Bash calls) at 1 occurrence with a proposed one-line running-tend Test-Commands note, watched for recurrence. It recurred this window but as one efficient probe, not a multi-call dance — the model handled it cleanly, so the waste that motivated the proposed note has not materialized. Not acting: adding guidance for a 2-occurrence, near-zero-cost pattern is exactly the noise the gates warn against. Watch stays open: if a future nightly again burns several Bash calls hunting for cargo, add the one-line note (cargo lives at $HOME/.cargo/bin).

Observation #3: open recurrence watches — none fired

• Evidence level: Confirmatory (continuity).
• Session-cap re-arm (2026-06-30 Observation Add CI workflows and fix cross-platform test failures #1: a fix-PR run re-arming CI-poll loops past the 3600s cap): did not fire — no run hit the session cap this window (longest 32 min); the triage that shipped fix: preserve subdirectory position on wt remove #3344 completed in 22 min.
• tend#694 degenerate CI-poll-spin: stays closed (resolved by the 0.1.7 deploy; the 20+ min runs used clean blocking polls).
• Flake-retry / lychee "rerun = separate run": no lychee activity, no maintainer-closed flake/mitigation PR. No escalation.
• picker/PTY ci-fix de-flake-thrash (PR #3271): no recurrence — all ci-fix runs skipped on green main.
• mention-handle startup failures (2026-06-28 watch): none this window.

Run 28577099039 — 2026-07-02T08:47:32Z

Window: 24h ending ~2026-07-02T08:43Z. ~54 completed tend runs (22 token-bearing in the report; the rest skipped ci-fix-on-green / mention-dispatch no-ops, plus low-cost notification polls). 0 failed / cancelled / timed-out runs. Spend: $32.53 API-list cost (108.5K in / 163.7K out / 1.3M cache-create / 20.4M cache-read) across 337 turns. Per-workflow: tend-review $10.70 (5 runs / 108 turns), tend-nightly $6.14 (1 / 41), tend-triage $3.51 (2 / 42), tend-mention $3.51 (8 / 45), tend-notifications $3.25 (4 substantive / 42), tend-review-runs $2.97 (1 / 30), tend-ci-fix $2.45 (1 / 29). A quiet, low-cost day; no cost outlier — heaviest single run is the nightly sweep at $6.14.

Long-running / near-timeout jobs: none near-timeout (default 360-min cap; 90% = 324 min). Longest jobs: tend-nightly 28572919678 20 min (success, full sweep → PR #3354), tend-ci-fix 28572338035 20 min (success → PR #3353), tend-review 28538805045 18 min (thorough feature review of #3350). None near the 3600s session cap.

Outcomes — healthy:

• 4 bot PRs merged (all by max-sixty): #3347 (readme month → July), #3348 (drop misleading mutual-exclusivity tests), #3353 (fix ETXTBSY flake in run_custom signal test), #3354 (correct run_pipeline concurrent-group docstring).
• 0 bot PRs closed-without-merge → no maintainer corrections this window.
• 1 bot issue opened: #3352 (auto "Nightly tests failed", still open — see Observation Add CI workflows and fix cross-platform test failures #1).

Findings (passing gates): none

A clean, quiet 24h. Two behaviors stood out as exemplary:

• Triage↔ci-fix coordination on the nightly flake (no duplicate PR). The nightly feature-powerset job flaked on run_custom_propagates_signal_exit_code (an ETXTBSY write→exec race), auto-opening issue Nightly tests failed #3352. tend-ci-fix (28572338035, workflow_run) diagnosed the flake — same commit 5175153 passed at 05:00 and failed at 06:49 — and shipped PR fix(test): avoid ETXTBSY flake in run_custom signal test #3353. tend-triage (28572336694, issues event on Nightly tests failed #3352) independently reached the same root cause but found fix(test): avoid ETXTBSY flake in run_custom signal test #3353 and deferred to it — commented linking the PR and said the issue can be closed on merge, rather than opening a parallel PR. Exact "Same-root-cause-class triage" / dedup behavior. Both PRs merged.
• Heaviest review (28538805045, $5.56 / 49 turns) on feat(picker): flash alt-x removal-failure reasons in the header #3350 (feat(picker): flash alt-x removal-failure reasons) did full grounded verification — refactor-equivalence check, sequential-lock/deadlock analysis on the new background flashes, data-safety scan of the removal surface, a /code-review high 8-angle pass, and a CLAUDE.md convention check — found zero findings and approved with an empty body (correct no-noise convention). Approval stuck; PR merged.

Below-threshold observations (no action)

Observation #1: auto "Nightly tests failed" issue #3352 left open after its fix merged

• Evidence level: Low (1 occurrence; near-zero impact). Mild coordination gap, not a bot error.
• Detail: The nightly workflow auto-opened #3352 for the feature-powerset flake. The fix landed as ci-fix's PR #3353, which references the failing run (not the issue) in its body, so merging it didn't auto-close Nightly tests failed #3352. Triage correctly said the issue "can be closed once it merges," but no single run owns closing it after the linked PR merges ~50 min later in a separate session — so the issue dangles. No prior occurrence in the review-runs-tracking: 2026-06 #2955 (June) log; nightly failures are infrequent, so this is the first instance. Not acting: a 1-occurrence, cosmetic tracker-hygiene gap is below the Gate-1 threshold for a targeted fix (needs 2–3). Watch: if a future nightly-failure issue again survives its merged fix, consider a one-line running-tend note — either have ci-fix reference the auto-issue with Fixes #<n> when one exists, or have triage close it on the linking PR's merge.

Observation #2: open recurrence watches — none fired

• Evidence level: Confirmatory (continuity).
• Session-cap re-arm (2026-06-30): did not fire — longest run 20 min, no run near the 3600s cap.
• cargo-discovery probe (2026-06-29/07-01 watch, 2 occurrences, efficient): the nightly sweep this window ran without a multi-call cargo hunt; watch stays open, no escalation.
• Flake-retry / lychee "rerun = separate run": no lychee activity, no maintainer-closed flake/mitigation PR.
• picker/PTY ci-fix de-flake-thrash: no recurrence — all ci-fix runs skipped on green main except the one legitimate flake fix (fix(test): avoid ETXTBSY flake in run_custom signal test #3353).

Run 28649130094 — 2026-07-03T08:47:59Z

Window: 24h ending ~2026-07-03T08:47:59Z. 49 completed tend runs (21 token-bearing in the report; the rest skipped ci-fix-on-green / mention-dispatch no-ops, plus low-cost notification polls). 0 failed / cancelled / timed-out runs. Spend: $28.66 API-list cost (101K in / 123.3K out / 1.1M cache-create / 14.1M cache-read) across 260 turns. Per-workflow: tend-review $15.82 (4 runs / 105 turns), tend-notifications $4.27 (7 substantive / 47), tend-mention $4.11 (8 / 45), tend-nightly $3.20 (1 / 27), tend-triage $1.26 (1 / 17). A quiet, low-volume day. One cost concentration — the review of the large list --format=json feature PR — is fully justified (see below).

Long-running / near-timeout jobs: none near-timeout (default 360-min cap; 90% = 324 min). Longest jobs: tend-nightly 28645231148 19 min (full sweep, conflict resolution — see below), tend-review 28646891798 18 min (deep review of #3357), tend-review 28647860281 12 min, tend-review 28638282518 11 min. None near the 3600s session cap.

Outcomes — healthy:

• Review→fix→approve loop worked end-to-end on #3357 (feat(list): add JSON schema 2). First review 28646891798 ($10.57 / 47 turns — the day's cost outlier) did full grounded verification: 4 finder subagents (correctness / removed-behavior / cleanup / commit-producer verification), then a real codecov investigation — downloaded the cobertura.xml, intersected added-vs-uncovered lines in Python, and posted a COMMENT review flagging uncovered schema-2 serializer arms. The author pushed 01e8e888 "cover the schema-2 serializer arms codecov flagged" directly actioning the finding; the re-review 28647860281 ($1.38) then APPROVED with an empty body. The two reviews were not duplicative — legitimate re-review after a responsive push. The $10.57 is proportionate to a large multi-file feature PR.
• Multi-turn issue thread #3355 ("git-wt.exe flagged as Trojan by Defender") handled well across two workflows: triage 28634707171 explained the Wacatac.B!ml false positive; maintainer asked "how can we not have this happen?"; mention 28647641283 answered with a sourced code-signing comparison (SignPath Foundation / Azure / SSL.com eSigner / OV-EV), honest caveats, and offered a PR. Grounding verified: the referenced release surface (release.yaml, dist-workspace.toml allow-dirty = ["ci"], cargo-dist) all exist in the repo.
• Nightly 28645231148 resolved a real CHANGELOG.md conflict on bot PR #3328 (main cut 0.65.0, colliding with the PR's ## Unreleased), pushed f67ef655, green on all three platforms. Surveyed 14 files, found only two judgment-call nits, correctly skipped churn PRs. tend@latest init produced no workflow drift. Scope check: feat(diagnostic): surface pager/terminal env vars in the -vv report #3328 is bot-authored, so the push was in scope.
• Notifications correctly marked-read a docs(skills): make /wt-switch-create worktree creation unconditional #3356 merge notification with nothing actionable (self-conversation / human-activity guards). Correct restraint.
• 0 bot PRs closed-without-merge → no maintainer corrections this window. 0 bot issues opened; Nightly tests failed #3352 (prior window's nightly-flake issue) closed cleanly within the window.

Findings (passing gates): none

Below-threshold observations (no action)

Observation #1: open recurrence watches — none fired

• Evidence level: Confirmatory (continuity).
• cargo-discovery probe (2026-06-29/07-01 watch, 2 occurrences, efficient): the nightly this window ran no cargo-discovery calls at all (used uvx tend@latest init, no compile). Watch stays open, no escalation.
• Session-cap re-arm (2026-06-30): did not fire — longest run 19 min, none near the 3600s cap.
• Nightly-failure issue survives merged fix (2026-07-02 Observation Add CI workflows and fix cross-platform test failures #1): no nightly-failure issue this window (Nightly tests failed #3352 closed cleanly). Watch stays open.
• Flake-retry / lychee "rerun = separate run": no lychee activity, no maintainer-closed flake/mitigation PR.
• picker/PTY ci-fix de-flake-thrash: no recurrence — all ci-fix runs skipped on green main.

Run 28700791822 — 2026-07-04T08:49:00Z

Window: 24h ending ~2026-07-04T08:49:00Z. 46 completed tend runs (15 token-bearing in the report; the rest skipped ci-fix-on-green / mention-dispatch no-ops, plus low-cost notification polls). 0 failed / cancelled / timed-out runs. Spend: $17.35 API-list cost (69.9K in / 79.6K out / 754K cache-create / 9.3M cache-read) across 196 turns. Per-workflow: tend-review $5.24 (4 runs / 45 turns), tend-nightly $4.68 (1 / 40), tend-review-runs $2.13 (1 / 28, the prior review-runs run), tend-mention $2.65 (6 / 45), tend-notifications $1.45 (2 substantive / 20), tend-triage $1.20 (1 / 17). The quietest, lowest-cost window in the log (prior windows: $28–48). No cost outlier — heaviest single run is the nightly sweep at $4.68.

Long-running / near-timeout jobs: none near-timeout (default 360-min cap; 90% = 324 min). Longest: tend-nightly 28698827380 36 min — over the 30-min flag, but the time was legitimate CI polling on its own fix PR #3360 (two 9-min gated-CI-poll loops + Windows-specific polling; a nightly fix PR is gated, so this is correct CI-monitoring behavior, not waste). Next: tend-mention 28699086393 16-min handle (applied a review suggestion + gated CI poll), tend-review 28688622831 13 min ($2.51, thorough review of #3359). None near the 3600s session cap.

Outcomes — healthy:

• Review→fix→ack loop worked end-to-end on the nightly's own PR #3360 (docs(remote_ref): include Gitea in provider trait docstrings). tend-review 28699020583 reviewed the nightly's fix and found a genuine follow-on (the platform_label collision parenthetical still named only GitHub + Azure DevOps, omitting Gitea despite Gitea being a real 3-way collision via RefType::Pr + pull/{N}/head), posting an inline suggestion. tend-mention 28699086393 (pull_request_review event) applied it (commit 8ce0dd37) and replied with source-verified confirmation. Grounded, correct, deduped.
• Self-loop guards held. The review action left an empty COMMENTED review on docs(remote_ref): include Gitea in provider trait docstrings #3360, which fired a downstream pull_request_review event; the triggered tend-mention run 28699210961 correctly identified it as bot-authored self-triggered activity and exited silently (self-loop guard). The re-review run 28699206672 also correctly skipped (already-reviewed same commit, neither exception applies).
• Reviews stuck. fix(bench): restore worktree indexes after cache invalidation #3359 (fix(bench): restore worktree indexes) APPROVED; feat(list): add JSON schema 2 behind [list] json-schema #3357 (feat(list): JSON schema 2) COMMENTED→APPROVED. No undos, no human pushback, no maintainer corrections.
• 0 bot PRs closed-without-merge. 1 bot PR opened this window (docs(remote_ref): include Gitea in provider trait docstrings #3360, the nightly sweep; awaiting maintainer). 0 bot issues opened/closed.

Findings (passing gates): 1 → PR #3361

Finding #1: cargo not on the sandbox default PATH — first cargo call fails, fired twice this window

• Evidence level: High / structural (cargo is deterministically absent from the sandbox PATH). 4 total occurrences: 2 this window (nightly 28698827380 + mention 28699086393), 2 historical (2026-06-29 review-runs-tracking: 2026-06 #2955, 2026-07-01 above).
• Detail: Both runs that compiled Rust this window hit cargo: command not found on the first bare cargo check --lib, then recovered with a discovery probe + . "$HOME/.cargo/env" / export PATH="$HOME/.cargo/bin:$PATH". Prior runs deferred the one-line note while manifestations were preemptive probes; this window both were real failures spanning two workflow types (nightly + mention), meeting the 07-01 watch's escalation condition. Acted: PR #3361 adds a note to running-tend Test Commands — source $HOME/.cargo/env before the first cargo/task command. Gate 1: structural + 4 occurrences ✓. Gate 2: targeted one-paragraph addition ✓.

Below-threshold observations (no action)

Observation #1: empty COMMENTED review from the review action spawns a needless self-triggered mention run

• Evidence level: Low (1 occurrence; cosmetic; harness/action-level, not a tend skill decision). No tend session posted the empty COMMENTED review (4629098157, 07:31:27Z) via a visible tool call — the review runs and mention run all posted via explicit gh api .../replies or exited silently — so it's most likely claude-code-action review-wrapper machinery submitting an empty review when the agent adds no inline comments.
• Detail: The empty review fired a pull_request_review event → tend-mention 28699210961 (~$0.19, 3 turns) spun up and correctly exited via the self-loop guard. Net waste is one cheap session spin-up; the guard caught it. Not acting: 1 occurrence, cosmetic, and the root cause (if real) is in claude-code-action, not the repo skills. Watch: if empty review-action reviews recur and reliably amplify into self-triggered runs, consider filing upstream against tend/claude-code-action.

Observation #2: open recurrence watches — status

• Evidence level: Confirmatory (continuity).
• cargo-discovery probe (2026-06-29 / 07-01 watch): fired and escalated → PR skills(running-tend): note cargo needs $HOME/.cargo/env in the tend sandbox #3361 (see Finding Add CI workflows and fix cross-platform test failures #1). Watch closes on merge.
• Session-cap re-arm (2026-06-30): did not fire — longest run 36 min (nightly, all gated CI polling), none near the 3600s cap.
• Nightly-failure issue survives merged fix (2026-07-02 Obs Add CI workflows and fix cross-platform test failures #1): no nightly-failure issue this window (nightly succeeded, opened a code-quality PR not a failure issue). Watch stays open.
• Flake-retry / lychee "rerun = separate run": no lychee activity, no maintainer-closed flake/mitigation PR.
• picker/PTY ci-fix de-flake-thrash: no recurrence — the single ci-fix run 28698685112 skipped on green main.

Run 28735105759 — 2026-07-05T08:49:29Z

Window: 24h ending ~2026-07-05T08:43Z. 38 token-bearing tend runs in the report (rest skipped ci-fix-on-green / mention-dispatch no-ops, plus low-cost notification polls). 0 failed / 0 timed-out. 4 cancelled runs — all normal cancel-in-progress supersessions (two tend-review on freshly-pushed bot PRs #3364/#3366 superseded by successors; two tend-mention pull_request_review duplicates on the wt-switch-create PR). Spend: $53.39 API-list cost (196.6K in / 309.4K out / 2.1M cache-create / 40.5M cache-read). Per-workflow: tend-mention $28.21 (19 runs), tend-review $10.03 (9), tend-notifications $5.33 (7), tend-nightly $5.50 (1), tend-triage $4.32 (2). Higher than the recent $17–48 windows, but the uplift is two substantive mention PRs (see below), not waste — no degenerate spin.

Long-running / near-timeout jobs: none near-timeout (default 360-min cap; 90% = 324 min). Longest: tend-mention 28724277808 50 min handle (#3355 → PR #3366 code-signing docs — legitimate: authored a new docs page, opened the PR, gated CI polling, diagnosed a lint failure, added a lychee exclusion, rebased to absorb a sibling commit, re-pushed, re-polled; ~66 turns / $6.65, so most wall-clock was blocking CI waits, correct gated behavior on a bot's own PR). Next: tend-mention 28717534288 19 min (#3362 → PR #3364 Codex plugin feature, $11.30 the day's cost outlier). None near the 3600s session cap.

Outcomes — healthy, no maintainer corrections:

• 5 bot PRs opened, 0 merged, 0 closed-without-merge this window: #3361 (cargo-env skill note, prior window), #3363 (suppress Codex auto-discovery of Claude hooks), #3364 (ship Codex-native activity hooks), #3366 (SignPath code-signing policy page — human bemnlam APPROVED), #3367 (nightly: docs(hook) split cwd bullet). All awaiting maintainer. 0 bot issues opened/closed.
• Exemplary grounding on the two heavy mention PRs. feat(plugin): ship Codex-native activity hooks #3364 (28717534288) verified the entire Codex hooks schema from source before writing a line ("I must not fabricate the schema" → confirmed $PLUGIN_ROOT, the Stop/UserPromptSubmit event set, no SessionEnd, the inline-hooks manifest branch), edited manifest + CLAUDE.md + tests + CLI help + docs, ran targeted build/test/fmt/clippy/docs-sync/help-snapshot validation locally, deduped before gh pr create, and posted a source-verified issue reply. $11.30 is proportionate to a full multi-file feature PR with source verification. docs(code-signing): add SignPath Foundation code-signing policy page #3366 web-verified and source-verified every SignPath claim (cloned SignPath/github-action-submit-signing-request, checked its action.yml + latest release) and curl-checked every external URL before posting.
• tend-review no-noise convention applied correctly. feat(plugin): ship Codex-native activity hooks #3364 and docs(hook): split cwd exception bullet to match 'three cases' count #3367 show no review despite successful review runs firing — this is deliberate silence, not dropped work: 28718005342 fully reviewed feat(plugin): ship Codex-native activity hooks #3364, found no actionable finding (the only caveat — end-to-end Codex runtime unverifiable from CI — was already flagged by the author), and stayed silent; 28733517433 correctly noted docs(hook): split cwd exception bullet to match 'three cases' count #3367 is self-authored (GitHub rejects self-approval) with nothing to COMMENT and stayed silent. fix(plugin): suppress Codex auto-discovery of Claude hooks #3363, which had a finding, got a COMMENTED review. Correct restraint on all three.
• Nightly 28733256587 ($5.50) swept ~a dozen files, found no bugs, three cosmetic nits (one real: custom_subcommand_respects_global_dash_c_flag asserts only status.success() and can't detect -C forwarding breakage), and shipped the highest-value nit as PR docs(hook): split cwd exception bullet to match 'three cases' count #3367. No churn.

Findings (passing gates): 0 new PRs (1 gate-passing finding already covered by open PR #3361)

Finding: cargo-PATH watch fired again — real cargo: command not found, fix already open as #3361

• Evidence level: High / structural (cargo deterministically absent from the sandbox default PATH). New occurrences this window: the git-wt.exe is identified as a Trojan by Windows Defender Antivirus #3355 code-signing mention run 28724277808 hit a genuine cargo: command not found on its first bare cargo build/cargo test, then recovered by discovery (probe → export PATH="/etc/skel/.cargo/bin:$HOME/.cargo/bin:$PATH" re-exported in every subsequent Bash call, since PATH doesn't persist across tool calls). Session a4155577-0fb1-427e-9624-702e0813aa29.jsonl. Total occurrences across the log: 5+.
• Disposition — NO new PR (dedup): the fix is already open as #3361 (skills(running-tend): note cargo needs $HOME/.cargo/env), state OPEN/BLOCKED, awaiting maintainer merge. Opening a second would duplicate. Once skills(running-tend): note cargo needs $HOME/.cargo/env in the tend sandbox #3361 merges, future runs get the guidance up-front and skip the probe.
• Validated skills(running-tend): note cargo needs $HOME/.cargo/env in the tend sandbox #3361 in-sandbox this run: confirmed cargo is off the default PATH; . "$HOME/.cargo/env" (the PR's primary form) prepends /etc/skel/.cargo/bin and resolves cargo; the PR's fallback export PATH="$HOME/.cargo/bin:$PATH" also resolves it ($HOME/.cargo/bin/cargo is a valid rustup symlink). Both skills(running-tend): note cargo needs $HOME/.cargo/env in the tend sandbox #3361 forms work — the guidance is accurate as written. This run confirms skills(running-tend): note cargo needs $HOME/.cargo/env in the tend sandbox #3361 is correct and worth merging; no edit needed.

Below-threshold observations (no action)

Observation #1: mention spend/depth uptick — justified, not waste

• Evidence level: Confirmatory (healthy). tend-mention drove $28.21 of the $53.39 (vs $2.65–10 in recent windows), concentrated in two runs: the $11.30 Codex feature (feat(plugin): ship Codex-native activity hooks #3364) and $6.65 code-signing docs (docs(code-signing): add SignPath Foundation code-signing policy page #3366). Both shipped complete, source-verified, locally-validated PRs. Cost tracks the two substantive feature/docs asks that happened to land the same day, not degenerate looping. Not acting.

Observation #2: 50-min handle on the code-signing mention run — 1 occurrence, legitimate

• Evidence level: Low (1 occurrence; over the 30-min flag but far under the 360-min cap). The wall-clock was blocking CI polls on the bot's own gated PR plus a real rebase-to-absorb-sibling-commit coordination, not a stuck loop. Watch: if a mention run without a gated PR of its own runs >30 min, revisit.

Observation #3: open recurrence watches — status

• Evidence level: Confirmatory (continuity).
• cargo-discovery / cargo-PATH (escalated to skills(running-tend): note cargo needs $HOME/.cargo/env in the tend sandbox #3361 last window): fired again (see Finding). Watch stays open until skills(running-tend): note cargo needs $HOME/.cargo/env in the tend sandbox #3361 merges.
• Session-cap re-arm (2026-06-30): did not fire — longest run 50 min, none near the 3600s cap.
• Nightly-failure issue survives merged fix (2026-07-02 Obs Add CI workflows and fix cross-platform test failures #1): no nightly-failure issue this window (nightly succeeded → PR docs(hook): split cwd exception bullet to match 'three cases' count #3367). Watch stays open.
• Empty review-action review → self-triggered mention run (2026-07-04 Obs Add CI workflows and fix cross-platform test failures #1): no clear amplification this window — the pull_request_review-triggered mention runs (28724867395, 28727436379) were triggered by substantive reviews (the bot's COMMENTED review and human bemnlam's APPROVED on docs(code-signing): add SignPath Foundation code-signing policy page #3366), handled correctly. Watch stays open.
• Flake-retry / lychee "rerun = separate run": no maintainer-closed flake/mitigation PR; the one lychee change this window (docs(code-signing): add SignPath Foundation code-signing policy page #3366's .config/lychee.toml self-referential-.md exclusion) is a legitimate part of a new-docs-page PR, not a transient-timeout workaround.

Run 28780392674 — 2026-07-06T09:14:21Z

Window: 24h ending ~2026-07-06T09:08Z. 31 token-bearing tend runs in the report (rest skipped ci-fix-on-green / mention-dispatch no-ops, plus low-cost notification polls). 0 failed / 0 timed-out. 3 cancelled runs — all normal pull_request_target cancel-in-progress supersessions (two tend-review on the freshly-pushed GIT_* fix PR #3374, one on the "Correct Windows guidance" mention). Spend: $54.01 API-list cost (147.3K in / 269K out / 1.94M cache-create / 42.9M cache-read) across 482 turns. Per-workflow: tend-triage $17.42 (3 runs / 138 turns), tend-review $16.72 (14 / 186), tend-nightly $7.00 (1 / 50), tend-weekly $7.00 (1 / 33), tend-mention $4.97 (12 / 62), tend-notifications $0.90 (1 substantive / 13). In line with the recent $17–53 windows; the one cost outlier (triage $14.58) is a fully-justified multi-file fix (see below).

Long-running / near-timeout jobs: none near the GitHub 360-min job cap (90% = 324 min). Longest: tend-triage 28754826850 58 min (claude step 3459s = 96% of the 3600s session cap — the closest approach in the log, but the deliverable shipped green and was maintainer-visible before the risky tail; see Observation #1). Next: tend-nightly 28776270208 37 min ($7 sweep → PR #3379), tend-review 28766127227 26 min ($2.65, thorough review). None hit the 360-min job cap.

Outcomes — healthy, no maintainer corrections:

• 2 bot PRs merged this window: #3367 (docs(hook) cwd bullet split) and #3368 (weekly renovation 2026-07-05), both by max-sixty.
• 2 new bot fix PRs opened, awaiting maintainer: #3374 (fix(hooks): scrub inherited GIT_* discovery vars — from triage of issue Inherited GIT_* discovery vars are forwarded into user hooks, misdirecting hook git commands (can pollute core.worktree) #3373; 196+/7 files, all CI green incl codecov/patch) and #3379 (nightly refactor(invocation): use path_slash for argv[0] — textbook "Use Existing Dependencies" CLAUDE.md finding).
• 2 feature-request triages handled exemplarily (#3369 run-outside-a-repo, #3370 picker-with--x): both grounded, SHA-pinned source links, honest tradeoff framing, deferred to maintainer. Feature request: Interactive picker should run when --execute is specified without a branch name #3370 correctly recognized an alias can't solve it (the requires = "branch" clap constraint rejects -x before any alias/picker code runs) rather than reflexively suggesting one — good judgment against the "suggest an alias" default.

Below-threshold observations (no action)

Observation #1: session-cap near-miss — 58 min / 96% of the 3600s cap, but deliverable shipped before the risky tail

• Evidence level: Low→Medium (1 occurrence this window; new max approach to the cap). Structural driver (a gated triage fix PR must poll its own CI), but not waste and not a failure — the run completed success.
• Run: tend-triage 28754826850, 101 turns / $14.58, session 20251d87-0ad5-4bf5-adce-f7be280f5ca8.jsonl. Timeline traced from the log: investigate Inherited GIT_* discovery vars are forwarded into user hooks, misdirecting hook git commands (can pollute core.worktree) #3373 → write reproduction tests → fix (7 files) → full local validation (targeted tests + clippy + docs-sync check) → commit/push PR fix(hooks): scrub inherited GIT_* discovery vars from user hooks #3374 and post the issue comment (steps 34–38) → poll gated CI → caught a real fast-checks rustdoc-warning failure → reproduced locally → pushed the rustdoc fix → re-polled Windows jobs → final status. Every minute is legitimate work: the length is one substantive fix plus two CI-poll rounds and a genuine follow-up fix on the bot's own gated PR.
• Why it's fine: the deliverable (PR fix(hooks): scrub inherited GIT_* discovery vars from user hooks #3374 + the issue comment) was maintainer-visible at step 38, before the CI-poll tail that consumed the final ~30 min. A session-cap cutoff during polling would not have stranded any work — the PR was already pushed and the comment posted. This is the correct ordering (ship, then poll).
• Not acting: no fix needed — this is exactly the gated-fix behavior running-in-ci prescribes. Watch stays open (re-arms the 2026-06-30 session-cap watch, now at its closest approach). Escalate only if a future run actually ends at the cap with the deliverable still local (unpushed branch / unsent comment).

Observation #2: cargo-PATH fired again — fix #3361 still open (dedup, no new PR)

• Evidence level: High / structural (cargo deterministically absent from the sandbox default PATH). New occurrence this window: the triage run above hit cargo: command not found on its first bare build, then recovered via /etc/skel/.cargo/bin/cargo. 6+ occurrences across the log.
• Disposition — NO new PR (dedup): the fix is already open as #3361, OPEN since 2026-07-04, awaiting maintainer merge. The triage run's own dedup check even surfaced skills(running-tend): note cargo needs $HOME/.cargo/env in the tend sandbox #3361. Opening a second would duplicate. Watch stays open until skills(running-tend): note cargo needs $HOME/.cargo/env in the tend sandbox #3361 merges; per-run waste stays ~1 Bash call.

Observation #3: open recurrence watches — status

• Evidence level: Confirmatory (continuity).
• Session-cap re-arm (2026-06-30): closest approach yet (58 min / 96%), but did not fire — deliverable shipped before the tail (see Observation Add CI workflows and fix cross-platform test failures #1). Watch stays open, heightened attention.
• cargo-PATH / skills(running-tend): note cargo needs $HOME/.cargo/env in the tend sandbox #3361 (escalated 2026-07-04): fired again (Observation Test CI fixes and improvements #2). Watch stays open until skills(running-tend): note cargo needs $HOME/.cargo/env in the tend sandbox #3361 merges.
• Nightly-failure issue survives merged fix (2026-07-02): did not fire — nightly succeeded → code-quality PR refactor(invocation): use path_slash for argv[0] normalization #3379, no failure issue this window. Watch stays open.
• Empty review-action review → self-triggered mention run (2026-07-04): no clear amplification this window. Watch stays open.
• Flake-retry / lychee "rerun = separate run": no lychee activity, no maintainer-closed flake/mitigation PR.

Run 28853816604 — 2026-07-07T08:57:43Z

Window: 24h ending ~2026-07-07T08:53Z. 26 token-bearing tend runs in the report (rest skipped ci-fix-on-green / mention-dispatch no-ops, plus low-cost notification polls). 0 failed / 0 cancelled / 0 timed-out runs. Spend: $53.61 API-list cost (125.8K in / 188K out / 1.4M cache-create / 22M cache-read). Per-workflow: tend-review $28.99 (6 runs), tend-mention $9.38 (13), tend-nightly $8.19 (1), tend-notifications $4.61 (5), tend-review-runs $2.44 (1). In line with the recent $17–54 windows; the one cost outlier (a single review at $22.91 — the highest single-run cost in the log) is a fully-justified deep review of a 1065-line core-safety feature that found a real data-loss bug (see Finding).

Long-running / near-timeout jobs: none near the GitHub 360-min job cap (90% = 324 min). Longest: tend-nightly 28849122595 30 min ($8.19 sweep → PR #3383), tend-review 28839505937 26 min (the $22.91 review below), tend-mention 28848840184 22 min ($3.22 → PR #3382). None near the 3600s session cap.

Outcomes — healthy, no maintainer corrections:

• 4 bot PRs merged (all by max-sixty): #3360 (Gitea provider docstrings), #3364 (Codex-native activity hooks), #3374 (scrub inherited GIT_* vars), #3379 (path_slash argv[0] normalization).
• 2 new bot PRs opened, awaiting maintainer: #3382 (mention-driven follow-up from feat(plugin): ship Codex-native activity hooks #3364, at @ofek's explicit request), #3383 (nightly finding — a real correctness fix: JsonItemV2::from_list_item compared raw item.branch so a remote-only origin/main row got a spurious self-relation).
• 1 bot PR closed-without-merge — but the bot closed it itself, correctly. #3363 (fix(plugin): suppress Codex auto-discovery of Claude hooks): max-sixty asked @worktrunk-bot resolve conflicts; the mention run resolved them, found the resolution collapsed to zero net change against main because feat(plugin): ship Codex-native activity hooks #3364 had landed a superior fix for the same issue (Codex plugin hooks should not rely on compatibility with Claude #3362), and closed the PR with a clear superseded-by explanation. Exemplary — not a maintainer rejection.

Findings (passing gates): 0 new PRs

The one gate-relevant recurring pattern (cargo-PATH) is already covered by open PR #3361; opening a second would duplicate.

Below-threshold observations (no action)

Observation #1: new cost max — a review spawned a 33-agent /code-review workflow at $22.91, but found a real reachable data-loss bug

• Evidence level: Low→Medium (1 occurrence; new single-run cost max, prior high ~$14.58). Outcome was correct and high-value, so this is a cost/proportionality watch, not a failure.
• Run: tend-review 28839505937, $22.91 / 40 turns, session 9e0c0a78-8dc8-457d-95b0-a6628f11d676.jsonl, reviewing #3380 (feat(approvals): add wt config approvals list and clear --stale, +1065/-51 across 23 files — core approval-gating logic).
• Detail: The review ran /code-review high as a Workflow with 33 subagents (8 finder angles + adversarial verify), reported "2 CONFIRMED, several PLAUSIBLE, ~20 refuted", then the main session grounded the top finding itself by tracing config resolution. The 33-agent fan-out is ~8× the ~4-finder pattern prior heavy reviews used (feat(list): add JSON schema 2 behind [list] json-schema #3357 $10.57, feat(picker): flash alt-x removal-failure reasons in the header #3350 $5.56), and drove ~$16 of the run's cost.
• Why it's not a problem this window: the review found a genuine, reachable data-safety bug — clear --stale with an absent per-worktree .config/wt.toml treats "zero configured commands" as "everything is stale" and silently wipes all repo-wide approvals (inconsistent with add_approvals, which errors ProjectConfigNotFound; the path was untested). Posted as a COMMENT (not a rubber-stamp approval) with two SHA-grounded inline comments. The author pushed a fix (fb5d1958), the re-review 28840708827 ($1.26) APPROVED, and max-sixty merged. Textbook review→fix→approve loop on exactly the kind of change (large, core, data-safety-adjacent) that warrants deep verification.
• Not acting: 1 occurrence with a correct, valuable outcome. Writing a "cap review fan-out" rule now would be "saw it once, wrote a rule" and risks degrading review quality on large core PRs where thorough fan-out is warranted. Watch: if review runs routinely fan out to 30+ agents on small PRs (where a 4-finder pass would suffice), or if a 30+-agent review produces no confirmed finding, escalate — a running-tend/review-reference note to size the /code-review fan-out to PR scope would then be justified.

Observation #2: open recurrence watches — status

• Evidence level: Confirmatory (continuity).
• cargo-PATH / skills(running-tend): note cargo needs $HOME/.cargo/env in the tend sandbox #3361 (escalated 2026-07-04): the nightly compiled Rust (→ PR fix(list): don't give a remote-only default-branch row a self-relation #3383), so the pattern almost certainly recurred, but the fix is already open as #3361 (OPEN since 2026-07-04). Dedup applies — no new PR. Watch stays open until skills(running-tend): note cargo needs $HOME/.cargo/env in the tend sandbox #3361 merges.

Spend: $20.45 API-list cost (68.6K in / 91.6K out / 848.3K cache-create / 10.3M cache-read) across 205 turns — the lowest-cost window in the log. Per-workflow: tend-review $4.93 (3 runs / 59 turns), tend-notifications $2.77 (4 substantive / 33), tend-mention $2.23 (6 / 27), tend-nightly $6.18 (1 / 29), tend-triage $2.20 (1 / 28), tend-review-runs $2.14 (1 / 26). No cost outlier — the highest single run is the nightly at $6.18, fully justified (CHANGELOG conflict resolution + build + tests on PR #3328). The window centered on a human-cut v0.66.0 release (#3385, #3386); the bot opened 0 PRs / 0 issues this window.

Long-running / near-timeout jobs: none near the GitHub 360-min job cap (90% = 324 min). Longest: tend-nightly 28924279047 24 min ($6.18, conflict resolution on #3328), tend-review 28915248297 16 min ($2.69, release-PR review), tend-review 28915864064 13 min. None near the 3600s session cap.

Outcomes — healthy, no maintainer corrections:

• Release reviews stuck. tend-review APPROVED both release PRs (#3385 with a grounded comment classifying a full-tests (windows-2022, windows) failure as a transient runner flake on a version-bump PR, correct per running-tend flake guidance; #3386 empty-body APPROVE). Both merged by max-sixty.
• Triage → reporter satisfied → closed. #3384 ("wt step copy-ignored but with symlinks", by vnea): triage 28883153660 + the mention reply 28883628271 explained the deliberate copy-not-symlink default (isolation / no cross-worktree target/ corruption) with a workaround; reporter replied "this is sufficient for me" and closed it. Grounded, well-scoped.
• Nightly resolved a real conflict, pushed, correctly did not merge. 28924279047 merged main (which had cut 0.66.0) into bot PR #3328, resolving a CHANGELOG.md-only conflict (kept ## Unreleased above ## 0.66.0, dropped nothing), verified cargo build + all 11 diagnostic tests, pushed e69aaa25a, left the PR unmerged. Deliverable maintainer-visible; not stranded.
• 0 bot PRs closed-without-merge → no maintainer corrections.

Findings (passing gates): 1 → filed upstream tend#756

Finding #1: review-runs' own daily tracking-issue comment edit self-triggers a no-op tend-mention session (bundled defect)

• Evidence level: High / structural + invisible failure mode. 7+ occurrences — a claude-session-logs-n3349 artifact exists for every day 2026-07-01→07-07 (runs 28854230666, 28780829709, 28735321616, 28701029104, 28649438004, 28577450551, 28506262260/28506210615), all issue_comment / success no-ops. No prior review-runs entry noticed it (it never surfaces as a CI failure).
• Mechanism (traced through .github/workflows/tend-mention.yaml "Verify bot engagement"): review-runs appends findings by editing the bot's existing comment on the bot-authored tracking issue review-runs-tracking: 2026-07 #3349. The gate's COMMENT_AUTHOR_TYPE == "Bot" skip (tend fix: wt step copy-ignored fails in bare repository setups #606) is inert for User-type PAT bots — gh api users/worktrunk-bot --jq .type returns "User", not "Bot" — so the edit falls through to the ISSUE_AUTHOR == worktrunk-bot → should_run=true branch (intended for triaging bot-authored CI-failure issues, tend fix: restore error propagation in DWIM branch check #665) and spins a full mention session. Once a findings entry quotes the bot handle (the 07-07 entry did), the @<bot>-in-body branch re-matches on every subsequent edit too. Each session's self-loop guard correctly exits without posting — no wrong action — but it's ~$0.19–0.70 + a runner wasted per day, and it will recur daily for the rest of July (the tracking comment persists) and monthly thereafter.
• Disposition: bundled defect (generic to every review-runs/review-reviewers consumer — each accumulates a bot-authored monthly tracking issue edited daily), so filed against tend, not fixed repo-locally. tend#756 proposes an early guard — a bot editing its own comment is never a summons (sender.login == bot on issue_comment edited → should_run=false, before the @<bot> and bot-authored-issue checks) — plus keying the fix: wt step copy-ignored fails in bare repository setups #606 skip on author login not type. Sits alongside the fix: wt step copy-ignored fails in bare repository setups #606/fix(test): use marker file to avoid flaky PTY output capture in zsh test #607/fix: use full canonical path for project identifier fallback #747 no-op-session series. Gate 1: structural + 7+ occurrences + invisible ✓. Gate 2: targeted workflow-gate change ✓. No repo-local mitigation fully works (the bot-authored-issue path fires regardless of the handle quote), so the fix must be upstream.

Spend: $8.91 API-list cost (37K in / 44.2K out / 402.3K cache-create / 5.6M cache-read) across 111 turns — the lowest-cost window in the log. Per-workflow: tend-nightly $3.04 (1 run / 30 turns), tend-ci-fix $1.96 (1 / 27), tend-review $1.19 (1 / 15), tend-notifications $2.30 (3 substantive / 24), tend-mention $0.42 (1 / 5). No cost outlier — heaviest single run is the nightly at $3.04. A quiet day: the bot opened 0 PRs, opened+closed 1 issue (the established ci-fix transient open-and-close, see Observation #1).

Long-running / near-timeout jobs: none near the GitHub 360-min job cap (90% = 324 min). Longest: tend-review 28992120132 19 min ($1.19, dependabot bump #3387 review + gated CI poll over a concurrency-cancelled nightly), tend-ci-fix 29000797140 7 min, tend-nightly 29001508989 7 min.

The mention run 28992228059 (pull_request_review on chore: bump taiki-e/install-action from 2.82.9 to 2.82.11 #3387) self-loop-guarded and posted nothing.

Observation #1: running-tend transient-failure disposition ("comment or exit silently") lags the established open-and-close-issue practice

• Evidence level: Low (documentation/practice mismatch, not a bot failure). Not acting.
• Detail: running-tend §"CI Fix: Prefer Rerun for Transient Infrastructure Failures" says for a transient infra failure to "Comment on the run or exit silently." The ci-fix run instead opened and self-closed #3388 (labeled tend-outage) "to keep it discoverable and off the commit timeline." This is not a deviation to correct — it's a deeply established, maintainer-accepted convention: 30+ ci-fix: transient … open-and-close issues since 2026-05, a dedicated pre-existing tend-outage label, and zero maintainer pushback across the series. The bot followed the convention correctly and grounded the diagnosis well. The mismatch is that the documented guidance is stale/less-specific than the actual practice.
• Why not acting: no failure occurred, and the bot behaves consistently. Codifying "open-and-close a tend-outage issue" into running-tend would be documenting an implicit convention rather than fixing a problem — a judgment call that risks over-specifying. Watch: escalate to a one-line running-tend clarification only if (a) a future ci-fix run diverges — comments-on-run or exits-silently instead of open-and-close, creating inconsistency — or (b) the maintainer pushes back on the open-and-close issue noise.

Observation #2: ci-fix open-and-close issue fired 2 downstream skipped no-op runs — reinforces tend#756 family

• Evidence level: Confirmatory (continuity; harness/workflow-gate level, not a skill decision). Not acting — covered upstream.
• Detail: Opening+commenting+closing #3388 fired issues/issue_comment events that spun two no-op runs — tend-triage 29001160631 and tend-mention 29001161071 — both correctly skipped by the workflow gate (near-zero cost, runner spin-up only). This is the same self-trigger no-op family as the review-runs tracking-issue edit filed as tend#756 (OPEN since 2026-07-08); the 30+ ci-fix open-and-close issues are an older, higher-volume source of the same pattern. tend#756's proposed fix (a bot acting on its own issue/comment is never a summons) would cover these too. No repo-local mitigation; no new upstream issue (dedup with tend#756).

Observation #3: open recurrence watches — status

• Evidence level: Confirmatory (continuity).
• cargo-PATH / #3361 (escalated 2026-07-04): fired again — both the ci-fix run (cargo: command not found → source "$HOME/.cargo/env") and the nightly compiled Rust. Fix still OPEN since 2026-07-04, awaiting maintainer merge. Dedup — no new PR. Watch stays open until skills(running-tend): note cargo needs $HOME/.cargo/env in the tend sandbox #3361 merges.
• Session-cap re-arm (2026-06-30, closest approach 96% on 2026-07-06): did not fire — longest run 19 min, none near the 3600s cap.
• Nightly-failure issue survives merged fix (2026-07-02): did not fire — the scheduled nightly succeeded; the repo nightly CI cancellation was handled by ci-fix as an open-and-close transient (no dangling failure issue).
• Empty review-action / self-trigger family (2026-07-04): fired cheaply — the review's empty-body APPROVE on chore: bump taiki-e/install-action from 2.82.9 to 2.82.11 #3387 spawned mention run 28992228059 (pull_request_review), which self-loop-guarded and posted nothing. Also reinforced by the ci-fix issue events (Observation Test CI fixes and improvements #2). Covered by tend#756. Watch stays open.
• Flake-retry / lychee "rerun = separate run": no lychee activity, no maintainer-closed flake/mitigation PR.
• picker/PTY ci-fix de-flake-thrash: no recurrence — the ci-fix run this window was a transient nightly cancellation, not a picker/PTY flake.

Run 29045563374 — 2026-07-09T19:52:48Z

Maintainer-flagged bad case: triage shipped a lossy docs workaround instead of diagnosing the root-cause fix (PR #3390 / issue #3389)

• Evidence level: Critical (directly flagged by maintainer @max-sixty — "log this as a bad case")

• Occurrences this run: 1

• Run ID: 29045563374

• Workflow: https://github.com/max-sixty/worktrunk/actions/runs/29045563374

• Source: PR docs(config): document branch | basename for worktree-path #3390 (closed), triage of issue feat: Handle branch namespace prefixes (e.g., 'claude/', 'feature/') in worktree mismatch flag #3389

• Trigger: docs(config): document branch | basename for worktree-path #3390 (comment)

• Detail:
  Triage of feat: Handle branch namespace prefixes (e.g., 'claude/', 'feature/') in worktree mismatch flag #3389 (the ⚑ branch/worktree mismatch flag fires when an external
  agent CLI checks branch claude/frosty-kilby-92c7d3 into a dir named
  frosty-kilby-92c7d3) produced a docs-only PR recommending users reconfigure
  worktree-path to {{ branch | basename }}. Problems:

  1. Wrong altitude / lossy recommendation. basename is lossy — alice/foo
     and bob/foo both map to foo and collide on one directory, whereas the
     default sanitize keeps them distinct (alice-foo / bob-foo). The PR
     presented basename as the fix and only surfaced the collision downside
     after the maintainer pushed back ("why do we drop the prefix?").
  2. Jumped to a docs workaround over the root-cause code fix. The real issue is
     that is_worktree_at_expected_path compares only against the single
     sanitize-computed path, so an externally-created worktree that already dropped
     the prefix on disk always mismatches. A small logic change to tolerate the
     namespace prefix (accept both alice/foo→alice-foo and →foo) is a
     better fit than asking every affected user to adopt a lossy template. Triage
     didn't propose this until prompted.
  3. "Docs-only, no risk" framing masked a bad recommendation. The zero-code-risk
     framing made the PR look safe, but it would have steered users toward a
     collision-prone config. Low apparent risk ≠ good guidance.

• Lesson for triage: when a mismatch/false-positive report has an obvious
  configurable workaround, don't stop at documenting the workaround — check whether
  the workaround is lossy/foot-gunny, and weigh a proportionate root-cause code fix
  before opening a docs-only PR. Surface downsides of any recommended config in the
  PR body up front, not only when challenged.

• Outcome: PR docs(config): document branch | basename for worktree-path #3390 closed by maintainer; logged here per maintainer request.

Finding #1: triage shipped a lossy docs workaround instead of the root-cause code fix (PR #3390 / issue #3389) — maintainer-flagged, now codified

• Evidence level: Critical (maintainer @max-sixty explicitly said "log this as a bad case", #3390 comment). 1 occurrence sufficient at Critical.

It was presented as the fix, surfacing the collision downside only after the maintainer pushed back, and jumped to a docs workaround over the proportionate root-cause code fix (tolerate a dropped namespace prefix in the path-match check). Verified sanitize_branch_name at src/config/expansion.rs:403 and the branch_worktree_mismatch machinery in src/commands/list/layout.rs.

Below-threshold observations (no action)

Observation #1: 4× cost window ($204.85) — justified by feature/fix volume, not waste

• Evidence level: Confirmatory (healthy). The day's two cost outliers both shipped merged work: tend-mention 29045664083 ($28.48 / 200 turns — new single-run cost max, prior $22.91) implemented the --reap feature (issue-comment trigger → PR feat(remove): add experimental --reap to kill worktree processes #3396, 8 commits, merged); tend-ci-fix 29061983171 ($12.15 / 68 min) diagnosed+fixed a PTY test failure on main → PR fix(test): treat Linux PTY EIO-on-close as EOF in read helpers #3398, merged. 59 mention + 47 review runs reflect a high-traffic PR day (6 merges, 5 new opens). No degenerate spin. Not acting — cost tracks legit throughput. Watch: the 200-turn mention run is the closest approach to a turn cap in the log; escalate only if a future mention run hits the turn cap without shipping its deliverable.

Observation #2: open recurrence watches — status

• Evidence level: Confirmatory (continuity).
• cargo-PATH / #3361 (escalated 2026-07-04): the ci-fix/triage/nightly runs compiled Rust, so the pattern almost certainly recurred; fix still OPEN since 2026-07-04, awaiting maintainer merge. Dedup — no new PR. Watch stays open until skills(running-tend): note cargo needs $HOME/.cargo/env in the tend sandbox #3361 merges.
• Session-cap re-arm (2026-06-30, closest approach 96% on 2026-07-06): did not fire — longest 68 min (gated ci-fix polling its own CI), none near the 3600s cap. Deliverable (PR fix(test): treat Linux PTY EIO-on-close as EOF in read helpers #3398) was pushed before the poll tail — correct ordering.
• Nightly-failure issue survives merged fix (2026-07-02): did not fire — nightly 29076634343 swept clean, opened no failure issue.
• Empty review-action / self-trigger family (tend#756, filed 2026-07-08): unchanged, still OPEN upstream. The ci-fix: transient open-and-close (ci-fix: transient setup-nu 504 on 29033171816 (GitHub Actions incident) #3391) fired its usual downstream skipped no-ops; covered by tend#756. No new upstream issue (dedup).

Findings (passing gates): 0 new PRs

No finding passed both gates. The two gate-relevant recurring patterns this window (cargo-PATH, plugin-hooks) are both resolved — cargo-PATH moved to upstream tend#766 by maintainer decision, and the plugin-hooks regression was already fixed and documented (see below).

Below-threshold observations (no action)

Observation #1 (watch disposition CHANGE): cargo-PATH resolved to upstream tend#766 — #3361 CLOSED by maintainer, do NOT re-open a repo-local note

• Evidence level: Confirmatory (healthy resolution of a long-running watch). Not acting.
• Detail: The cargo-PATH watch (escalated to repo-local PR #3361 on 2026-07-04, deduped every window since) reached its terminal disposition this window. On review, max-sixty asked "can we fix by setting this up better?"; the bot traced the root cause into the tend sandbox (proxy/setup-sandbox.sh writes a hardcoded PATH that omits ~/.cargo/bin; GITHUB_ENV/GITHUB_PATH are deliberately excluded from the sandbox handoff, so no repo-local lever reaches it), and tend-agent filed max-sixty/tend#766 (narrow guard-append of ~/.cargo/bin + a general sandbox_setup:/sandbox_env: adopter knob). max-sixty closed skills(running-tend): note cargo needs $HOME/.cargo/env in the tend sandbox #3361 "closing and moving to upstream … we can add the command as soon as the ability gets added to tend," and the bot committed to a repo follow-up once the knob ships.
• Consequence for future runs: cargo will keep appearing off the sandbox PATH (the recovery probe is expected and correct), but the repo-local mitigation is now closed by maintainer choice — a future review-runs must not re-open a repo-local cargo-env note. Watch re-points to tend#766: the repo follow-up is only warranted after tend ships the sandbox_setup/sandbox_env knob (then .config/tend.yaml can source ~/.cargo/env).

Observation #2: bot-introduced plugin-hooks regression (#3382) caught by a reporter and fixed — exemplary self-correction, already codified

• Evidence level: Confirmatory (healthy; 1 occurrence, fully resolved). Not acting.
• Detail: Bot PR feat(plugin): Claude-scope the shared hooks payload #3382 (merged 2026-07-09, "Claude-scope the shared hooks payload") silently broke Claude Code plugin-hook loading — it renamed hooks/hooks.json→hooks/claude-hooks.json, but Claude Code discovers plugin hooks by convention at hooks/hooks.json and does not honor plugin.json's string-path override, so /hooks showed no worktrunk handlers and the 🤖/💬 markers stopped updating. A reporter caught it on Claude Code 2.1.207 → issue Claude plugin hooks silently stop loading after hooks.json → claude-hooks.json rename (#2677f05) #3417. tend-triage 29134574379 diagnosed the root cause (confirming the feat(plugin): Claude-scope the shared hooks payload #3382 rename was always redundant for the Codex scoping it intended, because the Codex manifest defines hooks inline, overriding convention discovery — verified against 2677f05^) and shipped PR #3418, reverting plugin.json byte-for-byte to its pre-feat(plugin): Claude-scope the shared hooks payload #3382 state. Merged by max-sixty.
• Why fully resolved — no durable guard needed: the constraint is already documented in plugins/worktrunk/CLAUDE.md (lines 45-47 and 82-83 spell out the convention and the exact Claude plugin hooks silently stop loading after hooks.json → claude-hooks.json rename (#2677f05) #3417/feat(plugin): Claude-scope the shared hooks payload #3382 lesson). This is the class of change CI can't verify (plugin hooks loading inside a live agent CLI — the running-tend "Don't ship fixes you can't verify" surface), so the regression was inherently un-catchable pre-merge from CI; the reporter→triage→fix→doc loop is the correct recovery. Watch: if the plugin-hooks payload area churns again with another net-negative rename despite the now-documented convention, revisit — but the doc guard makes recurrence unlikely.

Observation #3: open recurrence watches — status

• Evidence level: Confirmatory (continuity).
• cargo-PATH / skills(running-tend): note cargo needs $HOME/.cargo/env in the tend sandbox #3361 (escalated 2026-07-04): terminal — moved upstream to tend#766, skills(running-tend): note cargo needs $HOME/.cargo/env in the tend sandbox #3361 CLOSED (Observation Add CI workflows and fix cross-platform test failures #1).

The release skill contradicts CLAUDE.md on project maturity and library compatibility #3420 nightly-issue issues event correctly fired tend-triage 29143979964, which confirmed the doc-drift against the tree rather than duplicating (bot-authored-issue-with-no-prior-bot-comment path, correct).

Findings (passing gates): 0 new PRs

No finding passed both gates. The one notable pattern (long CI-poll tail chasing a non-required job) is a single occurrence of a visible, non-stranding efficiency issue with a correct outcome — below the Gate-1 threshold (see Observation #1).

Below-threshold observations (no action)

Observation #1: 80-min mention run re-armed CI polls ~50 min chasing the non-required feature-powerset job after all required checks were green — and the "3600s session cap" the log has tracked is disproven

• Evidence level: Medium (plausible efficiency issue, clearly seen once). Occurrences of this specific wasteful shape: 1. The broader long-CI-poll-tail watch (open since 2026-06-30) has fired repeatedly (07-04 36m, 07-05 50m, 07-06 58m, 07-10 68m), but every prior long tail waited on required checks or a genuine follow-up fix — this is the first tail spent almost entirely on a non-required job that hadn't failed.
• Run: tend-mention 29149822671, $5.17 / 72 turns, session 011befbb-977a-4a5a-ae80-a1d1178a9a4a.jsonl (claude-session-logs-n3408). Timeline traced from the log: verify termimad 0.35.1 → edit deps/workaround/tests → local validation → push + open PR chore(deps): bump termimad to 0.35.1, drop ragged-table panic workaround #3422 + reply to Canop (~11:10) → poll gated CI → catch a real rustfmt lint failure → fix + re-push → re-poll → all required checks green → then ~50 min re-arming the poll loop 7× (for i in $(seq 1 8); sleep 60/70) to chase feature-powerset, which ran 1h5m35s (confirmed on chore(deps): bump termimad to 0.35.1, drop ragged-table panic workaround #3422's check list — non-required; the required set is test (linux/macos/windows) + gate, all green well before). The bot eventually recognized it as "one slow non-blocking job," stopped, and recorded honest state.
• Why below threshold (no PR): (1) Outcome was correct — PR chore(deps): bump termimad to 0.35.1, drop ragged-table panic workaround #3422 + the reply were maintainer-visible ~55 min before the poll tail; nothing was stranded, and the PR merged. (2) The waste is visible in the cost/duration reports review-runs monitors — not an invisible failure mode. (3) The decision to re-arm past the recipe's 9-iteration cap is stochastic: the bundled running-in-ci CI-Monitoring recipe already caps at 9 iterations (~9.5 min) and says to record still-pending checks and end — the model chose to re-arm instead. (4) A repo-local "stop polling non-required jobs" note risks conflicting with running-tend's explicit "Non-required ≠ transient" rule (a non-required job can fail from a real regression). Gate 1 fails (Medium needs 5+; stochastic needs 5+); Gate 2 (new paragraph) needs 3+.
• Watch (escalation trigger): if a future gated-fix-PR run again burns >20 min re-arming polls to chase only non-required jobs (feature-powerset ~65m, benchmarks ~80m, nix-flake/release-target/minimal-versions) after all required checks (test (…) + gate + codecov/patch) are green, escalate to a targeted running-tend note — scoped as "record the still-running non-required jobs as in-flight and end; don't re-arm to chase them" (which does not conflict with "Non-required ≠ transient": a non-required failure is still actionable, this is only about not blocking the session on a not-yet-failed hour-long build). 2 clear occurrences would clear Gate 1.
• Factual correction for the log: prior entries repeatedly measured runs against a "3600s session cap" (e.g. "3459s = 96% of the 3600s cap" on 2026-07-06). This run's claude step ran 4800s (80 min) and completed success, ending because the bot chose to stop — not on a cap. So there is no 3600s wall-clock session cap (the tend claude@0.1.10 action's timeout is higher, or unset within the 360-min job cap). Future runs should stop framing durations as "% of 3600s"; the real ceiling is the 360-min GitHub job cap.

Observation #2: open recurrence watches — status

• Evidence level: Confirmatory (continuity).
• cargo-PATH / #3361 (terminal 2026-07-11 → upstream tend#766): the termimad/nightly runs compiled Rust and hit cargo off the sandbox default PATH (recovered via export PATH="$HOME/.cargo/bin:$PATH"), as expected. No repo-local re-open — per the 07-11 disposition, the repo follow-up is warranted only after tend ships the sandbox_setup/sandbox_env knob. Watch stays pointed upstream.
• Session-cap / long-CI-poll-tail (2026-06-30, prior closest 96% "of 3600s"): re-framed — the assumed 3600s cap is disproven (Observation Add CI workflows and fix cross-platform test failures #1); the watch re-points to the wasteful-non-required-poll shape with the escalation trigger above.
• Nightly-failure issue survives merged fix (2026-07-02): did not fire — the scheduled nightly opened a code fix PR (fix(shell): stop PowerShell wrapper leaking a stray exit-code line to stdout #3425), not a failure issue.
• Empty review-action / self-trigger family (tend#756, OPEN upstream): the fix(shell): stop PowerShell wrapper leaking a stray exit-code line to stdout #3425 branch fired the usual pull_request_target + pull_request_review sibling runs (one cancelled by concurrency, one handled); no new amplification. Covered by tend#756, no new upstream issue (dedup).
• 200-turn mention turn-cap watch (2026-07-10): did not fire — heaviest mention run this window was 72 turns.
• plugin-hooks payload churn (2026-07-11): did not fire — no plugin-hooks changes this window.
• Flake-retry / lychee "rerun = separate run": no lychee activity, no maintainer-closed flake/mitigation PR.
• picker/PTY ci-fix de-flake-thrash: no recurrence — all ci-fix runs skipped on green main.

Run 29236354095 — 2026-07-13T08:50:16Z

Window: 24h ending ~2026-07-13T08:44Z. 68 token-bearing tend runs in the report (many more skipped ci-fix-on-green / mention-dispatch no-ops and cancelled concurrency siblings with 0 tokens). 0 failed / timed-out runs (the only failure was worktrunk's own scheduled nightly CI 29229600264, a link-check false positive that the bots handled correctly — see below). Spend: $127.99 API-list cost (391.9K in / 667.8K out / 4.6M cache-create / 74.7M cache-read). Per-workflow: tend-review $82.01 (37 runs), tend-mention $17.01 (18), tend-nightly $7.83 (1), tend-notifications $7.28 (9 substantive), tend-weekly $6.61 (1), tend-ci-fix $4.00 (1), tend-triage $3.25 (1). A busy PR day (not a cost anomaly): the review spend is spread across ~20 distinct PRs — 5 dependabot bumps (#3444–#3448), several feature/fix PRs (#3438–#3443), and the bot's own #3450–#3452 — each re-reviewed on pushes. Heaviest single run is the mention at $7.30 (a maintainer directive, healthy — see below).

Long-running / near-timeout jobs: none near-timeout (default 360-min cap; 90% = 324 min). Longest jobs: tend-mention 29186790924 38 min (maintainer-directed Windows-flake fix → merged #3427), tend-ci-fix 29232404362 26 min (→ #3452), tend-weekly 29188217619 26 min (weekly sweep → merged #3428/#3429/#3430), tend-nightly 29231891910 22 min. None near the 360-min job cap.

Outcomes — healthy:

• 6 bot PRs merged (all by max-sixty): #3425 (PowerShell stray-exit-line fix), #3426 (release-skill reconcile), #3427 (Windows self-exit-1 picker test), #3428 (MSRV/toolchain → 1.96), #3429 (CI pin bumps), #3430 (Codex commit model bump).
• 3 bot PRs opened, awaiting maintainer, all CI-green: #3450 (nightly: drop stale path-mismatch comments left by feat(list): demote branch-worktree mismatch from red flag to dim info #3419, net −2 lines, grounded in e02453a), #3451 (nightly: fix stale FlagNote method reference, grounded in src/output/handlers.rs), #3452 (ci-fix: exclude generated plugin-skills mirror from link-check).
• 0 bot PRs closed-without-merge → no maintainer corrections this window.
• 1 auto issue opened: #3449 ("Nightly tests failed", still open — the underlying failure is fixed in fix(ci): exclude generated plugin-skills mirror from link-check #3452; got a correct dedup comment).

Findings (passing gates): none

A clean, high-volume day. Every substantive decision aligned with running-tend / running-in-ci:

• Nightly link-check failure correctly classified as real, not transient, and fixed structurally. worktrunk's scheduled nightly CI failed on a link-check File not found (not a [TIMEOUT]) — the generated plugin-skills mirror from fix(plugin): ship skills to Codex installs via a generated real-file mirror #3440 dereferences a README.md symlink, so the repo-root-relative <img src="docs/static/logo.png"> no longer resolves under the mirror. tend-ci-fix correctly distinguished this deterministic false positive from a transient lychee timeout (which running-tend says to leave alone) and opened fix(ci): exclude generated plugin-skills mirror from link-check #3452 excluding the generated mirror. Exactly right.
• Heaviest run was a maintainer directive with a clean outcome. The $7.30 / 38-min mention 29186790924 was on PR feat(step promote): add --format text|json flag (parity with rebase/push/etc.) #3424, which merged at 09:01:06 — but the triggering comment (max-sixty, 09:01:38, "please fix the windows flake in a new PR") landed after the merge and explicitly asked for a new PR. The bot correctly did not treat the merged PR as stale work; it opened test(switch_picker): tolerate Windows self-exit-1 on successful picker-create #3427 (merged). The "triggering PR already closed → exit silently" rule did not misapply.
• No stranded work: all three open bot PRs are maintainer-visible and CI-green; the heaviest mention and ci-fix runs both shipped their deliverables before ending.

Below-threshold observations (no action)

Observation #1: nightly link-check failure was root-caused twice — by tend-ci-fix (opened the fix) and tend-triage (deduped correctly)

• Evidence level: Low (efficiency nitpick; correct outcome; 1 occurrence of this specific shape). Structural — an auto create-issue-on-nightly-failure issue and a workflow_run-triggered tend-ci-fix both fire on the same failed nightly run, so two workflows independently see the same failure.
• Runs: tend-ci-fix 29232404362 ($4.00) diagnosed the symlink-dereference false positive and opened #3452 at 07:39. Separately, a triage/mention run handling auto-issue #3449 ($3.25 tend-triage 29232403321) independently re-derived the same root cause and commented on Nightly tests failed #3449 at 07:43.
• Why below threshold (no action): the outcome was correct — the second run deduped, pointing at "already fixed in fix(ci): exclude generated plugin-skills mirror from link-check #3452" rather than opening a duplicate PR (the healthy behavior we want). The only inefficiency is ~$3 of redundant root-cause analysis: the triage re-diagnosed the failure even though fix(ci): exclude generated plugin-skills mirror from link-check #3452 already existed for ~4 min when it posted. That's a single-occurrence, correct-outcome, visible-cost pattern — well below the Medium 5+ bar; Gate 2 (any code/skill change) unmet.
• Watch (escalation trigger): if a future nightly (or main) CI failure again triggers two workflows independently paying full diagnosis cost (auto-issue triage + ci-fix each re-root-causing the same failure) ≥2 more times, consider a running-tend note: when handling a create-issue-on-nightly-failure issue, check for an open bot fix/ci-* PR referencing the same run before re-diagnosing, and cheaply dedup to it. Not worth acting on one clean occurrence.

Observation #2: open recurrence watches — status

• Evidence level: Confirmatory (continuity).
• Wasteful non-required poll tail (re-framed 2026-07-12, escalation = a gated-fix run burning >20 min re-arming polls to chase only non-required jobs after required checks are green): did not fire. The two long gated-fix runs monitored required CI — test(switch_picker): tolerate Windows self-exit-1 on successful picker-create #3427 (Windows required matrix, ~20 min) and fix(ci): exclude generated plugin-skills mirror from link-check #3452, whose heavy non-required jobs (feature-powerset, full-tests, minimal-versions) were all skipped on the PR branch, so there was nothing to chase; its 26-min length is normal required-matrix-to-green monitoring.
• cargo-PATH / tend#766: nightly + weekly compiled Rust off the sandbox default PATH as expected; no repo-local re-open (watch stays pointed upstream pending the tend sandbox_setup knob).
• Nightly-failure issue survives merged fix (2026-07-02): the auto issue Nightly tests failed #3449 is still open with its fix (fix(ci): exclude generated plugin-skills mirror from link-check #3452) not yet merged — expected; will auto-close on merge. No fire.
• 200-turn mention turn-cap (2026-07-10): did not fire — heaviest mention was 65 turns.
• Empty review-action / self-trigger family (tend#756): the bot's own docs(switch): drop stale path-mismatch comments left by #3419 #3450–fix(ci): exclude generated plugin-skills mirror from link-check #3452 fired the usual pull_request_target + pull_request_review sibling runs (cancelled-by-concurrency 0-token pairs); no new amplification. Covered upstream, no new issue.
• Flake-retry / lychee "rerun = separate run" and picker/PTY ci-fix de-flake-thrash: no recurrence.
• Factual note for the log: the "3600s session cap" framing was disproven last window (a claude step ran 4800s to success); durations this window are framed against the real 360-min GitHub job cap.

Run 29318220207 — 2026-07-14T08:37:26Z

Window: 24h ending ~2026-07-14T08:31Z. 73 token-bearing tend runs in the report (many more skipped ci-fix-on-green / mention-dispatch no-ops and cancelled concurrency siblings with 0 tokens). 0 failed / 0 timed-out runs. ~8 cancelled runs — all normal cancel-in-progress supersessions ($0 tokens: tend-review 29303711417/29293515009/29292963572/29291752766, tend-mention 29314654015/29313924387/29313450455/29292945090). Spend: $125.73 API-list cost (400K in / 742.8K out / 4.5M cache-create / 78.7M cache-read). Per-workflow: tend-review $72.26 (29 runs), tend-mention $24.39 (29), tend-triage $8.65 (3), tend-nightly $7.57 (1), tend-notifications $6.38 (7), tend-ci-fix $3.97 (3), tend-review-runs $2.51 (1, the prior day's run). A busy multi-PR day in line with yesterday's $127.99 — the review spend is spread across the #3462 fix's commit churn (re-reviewed on each push), 5 dependabot bumps (#3444–#3448), and several human feature/fix PRs (#3438–#3442). Heaviest single run is tend-review 29315388703 at $9.83 (38 min, re-reviewing #3462 across its git show reworks). No cost outlier, no degenerate spin.

Long-running / near-timeout jobs: none near-timeout (default 360-min cap; 90% = 324 min). Three jobs over the 30-min flag, all legitimate work orbiting the #3461/#3462 fix: tend-mention 29313094200 60 min (handle job, CI polling on a gated bot PR), tend-triage 29302669163 44 min (triaged #3461 → built+tested fix → PR #3462), tend-review 29315388703 38 min (re-review + CI-poll across #3462's churn). None near the 3600s session cap.

Outcomes — healthy:

• 6 bot PRs merged: #3450, #3451, #3452 (link-check fix), #3462 (triage of wt switch --create silently skips project pre-start hooks when primary worktree is on a non-default branch (bare-repo layout) #3461), #3463, #3464.
• 2 bot PRs open: #3466 (self-caught follow-up to fix: resolve project config from bare root when primary worktree is off default branch #3462, see Finding), #3457 (skill overlay from yesterday's maintainer feedback, still awaiting review).
• User issue #3454 (git-gtr config footguns) got a grounded, code-cited answer. Auto-filed nightly-failure issue #3465 was correctly recognized as already fixed by fix(ci): exclude generated plugin-skills mirror from link-check #3452 (link-check on the generated plugin-skills mirror) and closed — no duplicate PR.

Findings (passing gates): none (no PRs / issues opened this run)

Below-threshold observations (no action)

1. Self-initiated "refinement" reintroduced the exact bug the fix targeted (near-miss, self-corrected) — #3462 / #3466

• Evidence level: Critical-shaped outcome (a silent regression of wt switch --create silently skips project pre-start hooks when primary worktree is on a non-default branch (bare-repo layout) #3461 merged to main), but self-corrected by the bot and 1 occurrence — does not meet the acting bar. Stochastic (a model reasoning lapse, not a deterministic condition).
• Occurrences this run: 1.
• Run IDs: triage 29302669163 (built fix: resolve project config from bare root when primary worktree is off default branch #3462), review 29315388703 (reviewed it).
• Detail: fix: resolve project config from bare root when primary worktree is off default branch #3462 fixed a silent project-hook drop (wt switch --create silently skips project pre-start hooks when primary worktree is on a non-default branch (bare-repo layout) #3461, bare repo, primary parked off the default branch). After maintainer @max-sixty asked to "load it in with git show", the bot first pushed the correct cwd-independent ref git show <default-branch>:.config/wt.toml (commit a666864). It then made a self-initiated "refinement" (commit 228df21, "refactor: read default-branch config from HEAD, fold defensive paths") switching to git show HEAD:.config/wt.toml — reasoning in the doc-comment that "at the bare root the repo's own HEAD is a symbolic ref to the default branch." That reasoning holds only at the bare root: git show runs with discovery_path (the invocation cwd) as its working dir, so when wt is invoked from inside a linked worktree parked on another branch — the exact agent case this fix targets — HEAD is that worktree's branch, silently reintroducing wt switch --create silently skips project pre-start hooks when primary worktree is on a non-default branch (bare-repo layout) #3461. The PR's two regression tests invoke wt only from the bare root (where HEAD == default), so they stayed green and couldn't catch it. Merged to main (commit f66b49e34, src/git/repository/config.rs:734). The bot self-caught it ~12 min after merge and opened #3466 (verified end-to-end, reverts to the by-name absolute ref). Two contributing pulls worth watching for recurrence: (a) the switch was partly motivated by folding a defensive None branch that codecov/patch had flagged — i.e. reshaping still-needed production code to erase an uncovered guard, trading correctness for coverage; (b) a regression test for a cwd-dependent behavior that only invokes from the cwd where the behavior happens to work will pass while masking the bug. Neither pattern recurs elsewhere in this log yet. Not acting — the code fix is already in flight via fix: resolve default-branch project config by name, not cwd HEAD #3466 (thoroughly documented there), and 1 stochastic occurrence with exemplary self-correction is below the bar for a skill/CLAUDE.md rule. Recorded so a future run can count a recurrence.

2. Cost/throughput — busy PR day, healthy

• Evidence level: Confirmatory (healthy). $125.73 ≈ yesterday's $127.99; tend-review's $72.26/29-runs is spread across ~15 distinct PRs, each re-reviewed on push, plus the fix: resolve project config from bare root when primary worktree is off default branch #3462 fix's five-commit evolution. No single-run outlier (max $9.83), no turn-cap approach, no degenerate loop. Not acting.

3. Continuity

• Evidence level: Confirmatory. The historically-recurring cargo-not-on-PATH watch (resolved via skills(running-tend): note cargo needs $HOME/.cargo/env in the tend sandbox #3361, 2026-07-04) did not resurface as a failure this window. The claude-session-logs-nNNNN no-op-artifact item (upstream tend#756) remains as filed.

A moderate day, down from the prior window's $125.73. Heaviest single run is tend-mention 29387712890 at $11.25 (see Finding B).

Long-running / near-timeout jobs: none near-timeout (default 360-min cap; 90% = 324 min). Four jobs over the 30-min flag: tend-mention 29387712890 77 min (maintainer feature request on #3469 → PR #3473; ~18 min work + ~51 min CI polling, ~28 min avoidable — Finding B), tend-triage 29396645084 45 min (sound triage of #3476 → PR #3477; 59% inherent CI polling, no thrash), tend-mention 29389832429 30 min (review-response + CI monitoring on #3473), tend-nightly 29395896829 25 min (full sweep → PR #3475 + self-filed issue #3476). None near the session cap.

Outcomes — healthy:

• 2 bot PRs merged: #3466 (self-caught follow-up to fix: resolve project config from bare root when primary worktree is off default branch #3462, from the prior window), #3475 (nightly: docs help-pager stale setsid reference).
• Bot PRs open awaiting maintainer: #3473 (mention feature: config scope-note on misplaced keys, green), #3477 (triage fix: config show reflects wt switch --create silently skips project pre-start hooks when primary worktree is on a non-default branch (bare-repo layout) #3461 object-store fallback, green), #3457 (prior skill overlay).
• Healthy self-improvement loop: nightly self-filed issue #3476 (a genuine config show gap after wt switch --create silently skips project pre-start hooks when primary worktree is on a non-default branch (bare-repo layout) #3461) → triage reproduced + fixed it end-to-end in fix(config): show reflects the #3461 object-store project-config fallback #3477, with correct codecov/patch handling (collapsed a writeln! macro to cover a stranded ?, not a skip-guard).
• User issues got grounded, code-cited answers: #3469 (name/note worktrees → alias recipe, tested), #3470 (resize-rerender → skim/crossterm triage; surfaced Finding A).

Findings (passing gates)

Finding A → PR #3479: diagnostic-bundle path guidance is wrong for linked worktrees

• Evidence level: High / structural. Occurrences this run: 1 (verified — real user hit it).
• Run ID: 29401214344
• Session: triage 29378804591 + follow-up mention on Resizing terminal during interactive "wt switch" doesn't rerender #3470.
• Detail: The running-tend "Issue Triage" section told the bot the -vv bundle "writes .git/wt/logs/diagnostic.md". Following it, the bot asked reporter @KieranP to cat .git/wt/logs/diagnostic.md on #3470; they got Not a directory (os error 20) (ENOTDIR) and the bot acknowledged the instruction was wrong. In a linked worktree .git is a gitdir file, so that path can't resolve; the bundle lives under the git common dir (src/commands/process.rs:32,191; pending dir uses <git-common-dir>/wt/pending/ at process.rs:636). The path was also unnecessary — wt -vv already prints the exact absolute path + gist command (src/diagnostic.rs:365,392). Structural (deterministic in any linked worktree) + a targeted correction of an incorrect instruction → passes both gates. Acted: PR #3479 points the bot at the printed path/gist line and notes the git rev-parse --git-common-dir robust form.

Below-threshold observations (no action)

Finding B: mention run skipped the pre-merge gate → ~28 min of serial CI round-trips (#3473)

• Evidence level: Medium / stochastic. Occurrences this run: 1. Below the 5+ stochastic bar.
• Run ID: 29387712890 ($11.25, 77 min, 111 turns — the window's cost/duration outlier).
• Detail: On a real maintainer feature request (@max-sixty on Ability to name/add note for worktrunks #3469 → PR fix(config): redirect misplaced nested keys to the other config with a scope note #3473), the ~18 min of code work was clean (no edit thrash). But the bot opened the PR after only a partial local suite (integration tests), skipping cargo run -- hook pre-merge --yes — CLAUDE.md's prescribed all-in-one pre-ship gate (fmt + clippy + doc-links + --bins snapshots). It then paid three sequential ~9.5-min CI round-trips rediscovering, one at a time, a cargo fmt slip, a strict-rustdoc private-intra-doc-link failure, and --bins snapshot failures — all three caught by that one local command it skipped. The remaining ~2 loops were legitimate slow macos/windows waits. Deliverable shipped cleanly (green, no stranded work). This is a stochastic lapse against existing guidance (the command is already in CLAUDE.md Quick Start and running-tend Test Commands), so per the gates adding a new rule for 1 occurrence would be noise. Watch (escalation): if a future bot PR again pays ≥2 serial CI round-trips for locally-catchable fmt/clippy/doc/snapshot failures (≥1 more occurrence), add a targeted running-tend note reframing pre-merge --yes (not a test subset) as the mandatory pre-push gate for bot PRs, emphasizing each fast-check class otherwise costs a full CI round-trip.

Continuity — open recurrence watches

• cargo-not-on-PATH friction (tend#766): recurred mildly this window — the 45-min triage lost ~2.5 min to cargo-PATH discovery (resolved via /etc/skel/.cargo/bin) and the nightly compiled Rust off the default PATH. Negligible, no repo-local action; watch stays pointed upstream pending the tend sandbox_setup knob.
• Two-workflow double-diagnosis of a CI/nightly failure (2026-07-13 watch, escalate at ≥2 more): did not fire — nightly's self-filed wt config show doesn't reflect the #3461 object-store project-config fallback #3476 was handled by a single triage → fix(config): show reflects the #3461 object-store project-config fallback #3477; no ci-fix duplicate.
• fix: resolve project config from bare root when primary worktree is off default branch #3462/fix: resolve default-branch project config by name, not cwd HEAD #3466 self-refinement reintroducing a fixed bug (2026-07-14 watch): did not fire — fix: resolve default-branch project config by name, not cwd HEAD #3466 merged; no analogous "reshape production code to erase a codecov-flagged guard" or cwd-dependent-test pattern this window.
• 200-turn mention turn-cap: did not fire — heaviest mention was 111 turns (the 77-min fix(config): redirect misplaced nested keys to the other config with a scope note #3473 run), driven by CI-poll round-trips, not a runaway turn count on a single task.
• Wasteful non-required poll tail, empty review-action / self-trigger family (tend#756), lychee / picker-PTY de-flake-thrash: no recurrence.

Longest: tend-mention 29405485726 89 min handle (#3392 → PR #3480; feature work + codecov round + a review-response cycle + one locally-catchable CI round-trip — see Observation #1), tend-triage 29470413468 49 min (#3486 non-ASCII copy-ignored → PR #3487, green), tend-triage 29479506403 41 min (nightly self-filed #3491 → PR #3492, merged), tend-review 29434562331 26 min, tend-nightly 29478736482 25 min ($11.87 full sweep → PRs #3490/#3487, self-filed #3491). None near the 3600s session cap.

Outcomes — healthy, no maintainer corrections:

• 6 bot PRs merged (all by max-sixty): #3457 (prior skill overlay), #3473 (config scope-note), #3477 (config show object-store fallback), #3478 (flag stale default-branch cache), #3479 (the prior review-runs skill fix — diagnostic-bundle path), #3492 (restore hidden-subcommand completion coverage).
• 3 bot PRs open, awaiting maintainer: #3480 (warn on duplicate branch checkout — green), #3487 (copy-ignored non-ASCII filenames — green), #3490 (nightly survey docs corrections — green).
• 0 bot PRs closed-without-merge → no maintainer corrections this window.
• Healthy self-improvement loop: nightly 29478736482 self-filed issue #3491 (test_completion_validation no longer catches hidden flags) → triage 29479506403 reproduced + fixed it end-to-end in #3492, merged same day. Single triage owned it — no ci-fix duplicate.
• Exemplary grounded restraint on #3480. max-sixty questioned the git worktree remove hint twice ("should we hint with wt remove?" → "doesn't wt remove also take a path?"). The bot did full end-to-end verification against target/debug/wt, traced resolve_worktree_arg (resolve.rs:52-67) and remove.rs:124-130, and showed that wt remove <dup-path> on a duplicated named branch discards the path, deletes the shared branch, and orphans the survivor at 0000000 — a real data-safety bug it surfaced as a follow-up rather than caving to the (destructive) suggestion. Held its ground with grounded evidence; didn't over-agree. Positive baseline.

Findings (passing gates): none — 0 PRs / 0 issues opened

Below-threshold observations (no action)

Observation #1: pre-merge --yes skipped before opening a PR → 1 avoidable CI round-trip (rustdoc intra-doc-link) — 2nd occurrence, milder

• Evidence level: Medium / stochastic (a model choice to run a test subset rather than the full gate). Occurrences: 2 total — fix(config): redirect misplaced nested keys to the other config with a scope note #3473 (2026-07-15 window, 3 serial round-trips) and this window's feat(worktree): warn when a branch is checked out in multiple worktrees #3480 (1 round-trip). Below the 5+ stochastic bar and below yesterday's ≥2-serial-round-trips-per-PR escalation bar.
• Run ID: 29483833859 (analysis); the observed run is tend-mention 29405485726 ($10.64, 89 min, 92 turns — the window's cost/duration outlier). Session aafcd5ff-3fac-4279-a4cb-d80fdfc2da0d.jsonl.
• Detail: On max-sixty's handling duplicate checked-out branches #3392 feature request → PR feat(worktree): warn when a branch is checked out in multiple worktrees #3480, the code work was clean (no edit thrash). Local validation before gh pr create ran a targeted unit test + mock-stub build + INSTA_UPDATE integration snapshots + cargo fmt --check + cargo clippy --lib — but not cargo run -- hook pre-merge --yes (CLAUDE.md's all-in-one pre-ship gate, which runs strict rustdoc / doc-links). CI's fast-checks then failed on a public worktree_for_branch doc-comment intra-doc-linking a private warn_duplicate_checkout — a rustdoc failure pre-merge --yes catches locally. The bot fixed it (plain code span) and re-pushed: 1 avoidable round-trip. The run's other CI rounds were legitimate — a codecov/patch gap (not locally reproducible in-sandbox; task/cargo-llvm-cov aren't installed per running-tend) and a genuine review-response cycle (adapted a bot-review inline suggestion to name every shadowed worktree). Deliverable shipped green, no stranded work.
• Notable: both occurrences hit the same specific failure class — a doc-comment intra-doc link from a public item to a private item, caught only by CI's strict rustdoc. But today's was milder (1 round-trip vs yesterday's 3), and the remedy (run pre-merge --yes before pushing) is already in CLAUDE.md Quick Start and running-tend Test Commands. Not acting: a 2-occurrence stochastic lapse against existing guidance — restating a rule the bot already has won't move stochastic compliance, and per the gates would add noise. Watch (escalation, refined): escalate to a targeted running-tend note if either (a) a future bot PR again pays ≥2 serial CI round-trips for locally-catchable fmt/clippy/doc/snapshot failures (yesterday's bar, ≥1 more occurrence), or (b) the public→private rustdoc-intra-doc-link failure specifically recurs a 3rd time — at which point a one-line note ("pre-merge --yes runs strict rustdoc; a public doc-comment must not intra-doc-link a private item") would be a targeted, structural fix rather than a restated subset-vs-gate reminder.

Observation #2: cost/throughput — moderate, healthy

• Evidence level: Confirmatory (healthy). $93.86 sits mid-range (recent windows $20–126). tend-review's $34.43/18-runs is spread across ~10 distinct PRs re-reviewed on push. Two cost concentrations, both justified: nightly $11.87 (full sweep → two docs/fix PRs + a self-filed issue that became a merged fix) and the feat(worktree): warn when a branch is checked out in multiple worktrees #3480 mention $10.64 (a full feature PR + two maintainer-challenge rounds of grounded verification + a review-response cycle). No single-run turn-cap approach (heaviest 92 turns), no degenerate loop. Not acting.

Observation #3: open recurrence watches — status

• Evidence level: Confirmatory (continuity).
• pre-merge --yes skip → avoidable CI round-trip (2026-07-15 Finding B): fired mildly — 2nd occurrence, 1 round-trip (Observation Add CI workflows and fix cross-platform test failures #1). Watch stays open, bar refined.
• cargo-not-on-PATH friction (tend#766): recurred mildly — the feat(worktree): warn when a branch is checked out in multiple worktrees #3480 mention run did the usual source "$HOME/.cargo/env" / export PATH="/etc/skel/.cargo/bin:$PATH" dance on its first compile. Negligible; watch stays pointed upstream pending the tend sandbox_setup knob.
• Session-cap re-arm (2026-06-30, closest approach 96% on 2026-07-06): did not fire — longest run 89 min (mention handle, mostly blocking CI polls on a gated bot PR), none near the 3600s session cap.
• Two-workflow double-diagnosis of a CI/nightly failure (2026-07-13 watch): did not fire — nightly's self-filed test_completion_validation no longer catches hidden flags leaking into completions #3491 was handled by a single triage → fix(tests): restore hidden-subcommand completion coverage #3492; no ci-fix duplicate.
• fix: resolve project config from bare root when primary worktree is off default branch #3462/fix: resolve default-branch project config by name, not cwd HEAD #3466 self-refinement reintroducing a fixed bug (2026-07-14 watch): did not fire — no "reshape production code to erase a codecov-flagged guard" or cwd-dependent-test pattern this window.
• 200-turn mention turn-cap: did not fire — heaviest mention was 92 turns (feat(worktree): warn when a branch is checked out in multiple worktrees #3480), driven by CI-poll round-trips + a review cycle, not a runaway task.
• review-runs tracking-issue self-trigger (tend#756): remains as filed — this run's own review-runs-tracking: 2026-07 #3349 comment edit will again spin a no-op tend-mention session caught by the self-loop guard.
• empty review-action / self-trigger family, lychee / picker-PTY de-flake-thrash: no recurrence.

Run 29566616838 — 2026-07-17T08:37:03Z

Window: 24h ending ~2026-07-17T08:37:03Z. 68 completed tend runs (34 token-bearing in the report; the rest skipped ci-fix-on-green / mention-dispatch no-ops). 3 failed runs, all one incident (see below); 1 cancelled (normal concurrency supersede). Spend: $40.33 API-list cost (148.2K in / 231.0K out / 1.95M cache-create / 23.6M cache-read) across 438 turns. Per-workflow: tend-review $14.04 (9 runs / 146 turns), tend-notifications $9.91 (11 / 127), tend-mention $6.29 (11 / 73), tend-nightly $6.00 (1 / 49), tend-review-runs $2.96 (yesterday's run, in window), tend-triage $1.13 (1 / 14). A quiet, healthy day; no cost outlier — the heaviest single run is the nightly at $6.00.

Long-running / near-timeout jobs: none. Longest job: tend-nightly 29561801780 24 min (success, full sweep). No run approached the 360-min / 324-min near-timeout cap or the 3600s session cap.

Outcomes — healthy:

• Bot PRs merged this window: #3487, #3490, #3492, #3493. 0 bot PRs closed-without-merge → no maintainer corrections this window.
• Bot PRs opened, awaiting maintainer: #3499 (fix(shell): don't truncate config scan at a non-UTF-8 line — grounded fix, honest severity note, added regression test, no placeholders), #3500 (routine chore: update tend workflows 0.1.10 → 0.1.11).
• Bot issue opened: #3498 (tend check config-drift: repo-level release secrets not in secrets.allowed) — well-formed, correct.

Findings (passing gates): none

A clean, healthy 24h. All three failed runs are a single upstream incident (below); every substantive decision aligned with running-tend / running-in-ci. The fresh unreviewed bot PRs (#3499, #3500) and issue (#3498) are all well-grounded — owner-scoped links, no literal placeholders, honest severity framing.

Below-threshold observations (no action)

Observation #1: 3 tend-notifications preflight failures = GitHub REST-API incident (transient)

• Evidence level: Medium, but 1 incident (3 failures in one 59-min window, self-healed), not 3 independent occurrences. First recorded for this repo (not seen in review-runs-tracking: 2026-06 #2955 or review-runs-tracking: 2026-07 #3349 to date). Structural in that the preflight has no retry, but the trigger is a transient upstream outage.
• Runs: tend-notifications 29539892731 (22:33Z), 29541315462 (23:05Z), 29542419073 (23:32Z). All failed at the "Check for unread notifications" preflight step with exit code 1, ~4–6s in, before the tend action spawned (0 Claude tokens burned).
• Root cause: The step's first line COUNT=$(gh api notifications --jq 'length') (in the tend-generated workflow, .github/workflows/tend-notifications.yaml:29) has no retry/tolerance under set -eo pipefail. The three failures coincide exactly with a GitHub "Degraded REST API Availability" (major impact, API Requests component) incident — created 2026-07-16T22:51Z, resolved 2026-07-17T00:14Z (githubstatus.com). gh api notifications is a REST call; the next scheduled run at 00:05Z succeeded as the API recovered. Textbook transient upstream incident.
• Disposition: No PR. Per running-tend "Prefer Rerun for Transient Infrastructure Failures" (GitHub outages → no PR) and running-in-ci "Distinguish transient incidents from durable bugs." Impact is near-zero: the poll runs every 15 min (cron */15), so a failed poll is picked up the next cycle, and no tokens are spent.
• Watch: The preflight's no-retry gh api notifications is a bundled-tend robustness surface — it fails loudly (red run + maintainer email noise) during any REST-API blip rather than degrading. This is the first occurrence for this repo; below the bar to file upstream. If REST-API-incident-driven notifications-preflight failures recur across future windows, the accumulated evidence would justify a small upstream tend issue proposing a bounded retry / || exit 0 tolerance on the preflight probe.

Observation #2: cancelled tend-mention = normal concurrency supersede (no action)

• Evidence level: Confirmatory (expected behavior).
• Run: tend-mention 29517294411 — handle job cancelled at 16:53Z, superseded by a newer sibling mention run (29517492149, 16:53Z). Standard cancel-in-progress; not a failure.

Run 29637349359 — 2026-07-18T08:36:06Z

Window: 24h ending ~2026-07-18T08:36:06Z. 35 token-bearing tend runs (per token-report; the rest skipped ci-fix-on-green / mention no-ops). 0 failed / cancelled / timed-out runs in the window. Spend: $49.86 API-list cost (2K in / 333.8K out / 2.2M cache-create / 32.4M cache-read). Per-workflow: tend-review $25.10 (12 runs), tend-mention $8.73 (14), tend-nightly $6.58 (1), tend-notifications $5.63 (6), tend-triage $1.75 (1), tend-review-runs $2.07 (1). No cost outlier — highest single run is the nightly at $6.58 (was $6.99 on 2026-07-01; steady).

Long-running / near-timeout jobs: none near-timeout (nightly/mention have no timeout-minutes; default 360-min cap, 90% = 324 min). Longest: tend-nightly 29634823410 43 min (success — full sweep + gated PR CI-poll on its own #3511, legitimate), tend-mention handle 24 min, tend-review 14 min. None near the session cap.

Outcomes — healthy:

• All bot PRs merged, 0 closed-without-merge → no maintainer corrections/reversals this window. Merged: #3511 (nightly: wide-char branch-name width test), #3510 (mention: watchdog delay 4s), plus edge-of-window #3500 / #3499.
• Triage on #3501 (external orchestration feature ask): bot pointed at existing wt -C <repo> switch surface; reporter self-closed satisfied ("the current CLI already provides the portable orchestration surface"). Ideal deflection.
• tend-review added value on test(list): exercise real wide-char branch names in width test #3511: caught cosmetic assertion_line snapshot noise and posted an inline suggestion (applied as cleanup commit 985c7437). No role violation — it suggested, didn't push.

Findings (passing gates): none — 0 PRs / 0 issues opened

Below-threshold observations (no action)

Observation #1: nightly mv .snap.new .snap accept leaves insta's transient assertion_line metadata in committed snapshots

• Evidence level: Low (cosmetic; correct outcome; review already caught it). Structural — cargo-insta is not installed in the tend sandbox, so bots accept snapshots via INSTA_UPDATE=new cargo test + mv .snap.new .snap; the .snap.new carries assertion_line: which cargo insta accept would strip. mv keeps it every time (deterministic).
• Occurrences: 2 leaks currently in-repo — the one just cleaned on #3511 (nightly 29634823410, session f2565db7-f81f-40d1-9770-8ae59a21198c.jsonl), and a pre-existing switch_pr_azure_project_name_with_spaces.snap (assertion_line: 5514, still on main, passing).
• Why below threshold (no action): This is not a CI failure — commit e6b62120 CI was fully green with assertion_line: 25 present, and the nightly's local assert-mode spacing tests passed. The metadata is harmless noise that tend-review reliably flags. Acting would add a sandbox-specific workaround note (home: running-tend overlay) to save review one cosmetic suggestion — marginal value against the framework's caution about low-value guidance. Watch: escalate to a one-line running-tend note ("after mv-accepting a snapshot, delete the assertion_line: header line — cargo insta accept would strip it") if (a) a stale assertion_line ever causes an actual CI failure, or (b) review starts missing the noise and it accumulates (>3 leaks in-repo).

Observation #2: pre-merge-gate-skip watch — did NOT fire the wasteful shape this window

• Evidence level: Medium / stochastic. Prior occurrences: 2 — fix(config): redirect misplaced nested keys to the other config with a scope note #3473 (2026-07-15, 3 serial CI round-trips) and feat(worktree): warn when a branch is checked out in multiple worktrees #3480 (2026-07-16, 1 round-trip). Both below the 5+ stochastic bar.
• This window: the nightly again validated with a subset (local assert-mode spacing tests + cargo fmt --check) rather than cargo run -- hook pre-merge --yes, explicitly reasoning "commit and push (CI runs the full matrix + lints)". But the change was test-only and clean, so CI came back green with 0 round-trips — the wasteful shape did not fire. Watch stays open at 2 occurrences.

Run 29679991703 — 2026-07-19T08:37:53Z

Window: 24h ending ~2026-07-19T08:37:53Z. ~64 completed tend runs (23 token-bearing in the report; the rest skipped ci-fix-on-green / mention-dispatch no-ops and low-cost notification polls). 0 failed / cancelled / timed-out runs. Spend: $43.86 API-list cost (711 in / 314.6K out / 1.6M cache-create / 36.9M cache-read) across ~490 turns. Per-workflow: tend-nightly $12.32 (1 run / 100 turns), tend-review $17.33 (9 / ~154), tend-mention $9.45 (8 / ~118), tend-notifications $3.54 (4 substantive), tend-triage $1.22 (1 / 20).

Long-running / near-timeout jobs: none near-timeout (default 360-min cap; 90% = 324 min). Longest: tend-nightly 29679991703 nightly job 38 min (success, full sweep → 3 PRs); tend-mention 29678080714 19 min; tend-review runs 9–11 min. None near the 3600s session cap.

Cost outlier — nightly $12.32 / 100 turns (≈2× prior nightlies at $6–7): investigated, justified. Session 5f04f9cd-f39c-4ee7-b9ea-0f2ff4f7e598.jsonl. The elevated cost tracks more findings, not thrash: the sweep ran the PAT-scope audit + tend check (refreshed the standing secret-allowlist drift issue #3498), scanned bot/dependabot PRs for conflicts, ran a 3-subagent code survey, and did the workflow-update check — then opened 3 PRs: #3514 (real char_boundary panic fix in diagnostic.rs, merged), #3515 (format_log_output docstring correction), #3516 (pre-switch {{ branch }} resolution note, with a new verification test it ran locally before pushing). No error/retry loops in the log (the one non-zero exit was intentional test-scenario setup). Productive, not wasteful.

Outcomes — healthy:

• 2 bot PRs merged: #3513 (docs: workz custom-subcommand example), #3514 (nightly's diagnostic panic fix).
• 2 bot PRs open, awaiting maintainer: #3515, #3516.
• 0 bot PRs closed-without-merge. Bot self-review on fix(diagnostic): avoid panic slicing config/log at non-UTF-8 boundaries #3514 caught a hand-rolled helper → replaced with str::floor_char_boundary and applied it as author (legit reviewer-on-own-PR role boundary).

Findings (passing gates): none

Below-threshold observations (no action)

Observation #1: maintainer trimmed help-text detail on #3516 — single stochastic content-judgment lapse, watch

• Evidence level: Low→Medium (1 occurrence). Stochastic — a how-much-detail judgment the model may get right next time.
• Feedback: On #3516 (src/cli/mod.rs L1532, the # Hook Types after_long_help table), max-sixty commented: "I don't think we need this level of detail in the defn — please move / remove (including the old note)." The PR correctly fixed a stale {{ branch }} resolution note, but added implementation-level resolution detail to the user-facing hook help where the maintainer wants a higher altitude.
• Gate assessment: Does not pass. Generalizable-ish (help-text altitude), but 1 occurrence of a stochastic lapse, surfaced visibly (not invisible), no explicit codification request. Per the Learning-from-Feedback bar this is "saw it once" — below threshold. docs/CLAUDE.md and the writing-user-outputs skill already own help-text authoring; adding a one-off rule would be noise. Watch: if a future run again over-details an after_long_help/help-text definition and a maintainer trims it, that's the 2nd occurrence → propose a short running-tend (or docs/CLAUDE.md) note on keeping resolution/implementation detail out of command definitions.

Observation #2: open recurrence watches — none fired

• Session-cap re-arm (2026-06-30): did not fire — longest run 38 min, no run near the 3600s cap.
• cargo-discovery probe (2026-06-29 / 2026-07-01): nightly located its toolchain without a multi-call dance. No escalation.
• lychee "rerun = separate run" / flake-retry: no lychee or flake activity this window.
• ci-fix de-flake-thrash: all 5 ci-fix runs skipped on green main.
