- [bare cargo test WEDGES — use nextest](cargo-test-bins-wedges-use-nextest.md) ⭐⭐ IR-55: `cargo test -p spt --bins` hung 24min at 13.5s CPU (BLOCKED — a leaked `findstr .` child reads stdin forever under headless conhost; serial harness stalls every t
- [live-agent env reds broker-stop rigs](live-agent-env-reds-broker-stop-rigs.md) ⭐ the runner's identity vars (OWL_SESSION_ID/SPT_AGENT_ID/SPT_ENDPOINT_ID) make the shipped guard refuse a test's daemon-stop — scrub the three in the rig; env-differential o
- [generous bound is FREE on an early-exit poll](generous-bound-is-free-when-the-poll-exits-early.md) ⭐⭐ tight bound buys no speed, only load flakes; ask per ARM (kill bound ≠ success bound); elapsed wait MUST ride the red — at-budget vs under-budget i

- [two background jobs, ONE output path](two-background-jobs-one-output-path.md) ⭐⭐ reused `> $S/172-spt.txt` across two overlapping runs; the later grep read the earlier run's file and printed `EXIT=0` beside `test result: FAILED` — impossible for one c
- [mutate the DEFECT not the trigger](mutate-the-defect-not-the-trigger.md) ⭐⭐ trigger-only mutation vs standing defense measures nothing; only defense-removing survival indicts the test.

- [pool sweep is BLIND to a System32 victim leak](pool-scoped-sweep-blind-to-system32-leak.md) ⭐⭐ pool 0/0 while `cmd`+`ping` leaked from a withheld kill; reap the victim by COMMAND LINE, never by image name, and report BOTH predicates' counts — either a

- [a lost continuation backslash COMPILES and PASSES](a-lost-continuation-backslash-compiles-and-passes.md) ⭐⭐ a Rust literal that loses its trailing `\` bakes source indentation into the RENDERED text; W3: `xtask check` flagged a 14-space run in a diagnos
- [a long foreground `sleep` becomes a SHORT background one](a-long-foreground-sleep-becomes-a-short-background-one.md) ⭐⭐ Bash moves any command past its ~120s timeout to the background, so `sleep 590` waits ~2min and you poll 5x more than you intend. Mea
- [clippy COMPILES, it never RUNS a test](clippy-compiles-it-does-not-run-tests.md) ⭐⭐ `--all-targets` builds test targets, which is why it feels like coverage; it cannot tell you a test PINNED the string you changed. A DIAGNOSTIC-STRING lane needs the own

- [a census must be cfg(test)-AWARE](population-census-must-be-cfg-test-aware.md) ⭐⭐ grep cannot see `#[cfg(test)]`, so a call-site list mixes prod and test and still reads as an enumeration. releases#57: the filed issue, the JIT plan AND my own carried-fo
- [truncated grep = wrong POPULATION](truncated-grep-read-as-the-population.md) ⭐⭐ `| head -N` on a sweep SILENTLY sets scope; count first, list untruncated, classify every survivor — cost me a missed rename site.
- [census pattern encodes an assumption](string-census-pattern-encodes-an-assumption.md) ⭐⭐ two faces measured (w1t3): line-continuation split the token across lines (rg -U is the population check), and a `token+subcommand` pattern was blind to rendered BA

- [discriminator question](discriminator-question.md) ⭐⭐ 9 instances; newest = auditing a PEER’s one-command discriminator: if ONLY the failing path emits the string you grep, its absence from a green run is a TAUTOLOGY, not a measurement — ask which c
- [a louder red hides a quieter one](a-louder-red-hides-a-quieter-one.md) ⭐ todlando 2026-09-08: four golden cells were red for TWO reasons — my new doubled-`type` defect AND a literal envelope expectation predating W2 msg-id; fixing the loud one left them
- [is this red MINE](is-this-red-mine-delta-test.md) ⭐⭐ 2nd face: THE RED THAT CONFIRMS YOUR HYPOTHESIS needs the delta test most and gets it least. My rig died reproducing the frozen HFENDULEAM signature EXACTLY (spool.db + untaken briefing + no info.json
- [failed JOB ≠ test victim](failed-job-is-not-a-test-victim.md) ⭐⭐ 12 failed jobs = 3 real victims; all-pass nextest summary ⇒ read the STEPS api, cross-platform repeat ⇒ code red not victim; rerun behaviour PER SHA; compare SIGNATURES not counts.
- [assert string ≠ signature identity](assert-string-identity-must-include-the-predicate-subject.md) ⭐⭐ two "exact repeats" were pre-fix + post-fix mechanisms; the "respelling" WAS the fix — diff the predicate's SUBJECT chain, not the message · [empty
- [carried jobs inflate attempt rows](rerun-carried-jobs-dedupe-executions.md) ⭐⭐ partial rerun COPIES untouched jobs into the new attempt with ORIGINAL started_at; a carried failure = the SAME observation. Rate math dedupes on (run, box, started_at). ⚠

- [dispatch-window legs must name the GOLDEN BOX](dispatch-window-legs-must-name-the-golden-box.md) ⭐⭐ filled a golden's wait with my own gate legs ON the golden's Windows box; a TOTP cell stretched 17x, its gate's 1s backoff refused a valid code — the r
- [pre-fire check reads the DISK FLOOR](prefire-check-reads-the-disk-floor.md) ⭐⭐ process census is blind to a FINISHED build's dir; golden died at the 32 GiB preflight, zero test signal. ⚠ one floor reading = SNAPSHOT: C: swung 45 GB in 24min untouched 
- [pre-register the STATISTIC, not just the prediction](pre-register-the-statistic-not-just-the-prediction.md) ⭐⭐ even-N median is a CONVENTION wearing a statistic's authority: ten 1s + ten 3s gives lower=1 FALSIFIED, upper=3 SURVIVES, avg=2 SURVIVES — s
- [a battery is SILENT about arms no cell drives](a-battery-is-silent-about-arms-no-cell-drives.md) ⭐⭐ a claim that ENUMERATES is a test plan: "all six kinds", "every surface", "both directions". My own W3 asserted all six IO kinds visible in the REQ title

- [cargo test --tests STOPS at the first failing binary](cargo-test-tests-stops-at-first-failing-binary.md) ⭐⭐ every suite after the failure silently never runs — a "clean" rerun is evidence about the PREFIX; --no-fail-fast for any sweep claiming suite-w

- [hand-built walk ≠ enum pin](hand-built-walk-is-not-an-enum-pin.md) ⭐⭐ array + `len` assert stay trivially true when a variant is added; only a wildcard-free match at the PROD sites compiles red. Kin: a predicate parsing half an address re-opens the ru
- [panic MESSAGE is pre-authored](panic-message-is-preauthored-not-a-finding.md) ⭐⭐ names ONE mechanism whatever fired; read the gate line's numbers — a deficit PREDATING the window can't be caused inside it; immunity that's only a comment can't discrimi
- [assert GATES on status, PRINTS stderr](assert-gates-exit-status-but-prints-stderr.md) ⭐⭐ condition and message read different channels ⇒ log is MUTE on cause; `status.code()` 101-vs-1 lost, stdout invisible; a warn-only line above the panic is not the
- [test NAME asserts what the FIXTURE never creates](test-name-asserts-what-fixture-never-creates.md) ⭐⭐ gate not fooled, READER is; `std::process::id()` can never build an identity mismatch — read the fixture, never the name. 2nd face: the seeding HELPE

- [a PRESENCE control needs the FAULT's population](presence-control-scoped-to-the-faults-population.md) ⭐⭐ walked the whole doc asserting the set CONTAINS the verb — the artifact's own PREAMBLE prescribes it too, so the arm was green over the exact sile
- [a literal count floor is a FOSSIL](literal-count-floor-is-a-fossil-of-the-old-subject.md) ⭐⭐ `checked.len() >= 3` encoded how BIG the subject was, not that the instrument saw anything; a ruled partition shrank the briefing to one command and the cell re

- [cargo builds pkg bins for int tests](cargo-builds-package-bins-for-integration-tests.md) ⭐⭐ same-package fixtures ALREADY guaranteed; env! adds NO edge — gap is cross-package + UNIT tests; bindeps needs nightly, nextest needs the config form.
- [cargo test --bins never EMITS fixture exes](cargo-test-bins-never-emits-fixture-exes.md) ⭐⭐⭐ RECURRED 2026-08-29 on the entry's own author, WITH the entry written: prebuilt `-p spt --bins` from RECALL and ate three fixture reds in a row (mock-session,

- [pool refusal's TAIL reads as a release confirmation](pool-refusal-tail-reads-as-release-confirmation.md) ⭐ `tail -2` on a pool verb returns the releases#103 rationale blurb — the LAST line of the REFUSAL — which reads like success; 4/4 failed releases
- [the FIRST claim on a foreign pool must refuse](the-first-claim-on-a-foreign-pool-must-refuse.md) todlando 2026-09-08 W3: `cargo run -p xtask -- pool-claim` builds THROUGH the pool it is claiming, so a released foreign pool refuses SPT_POOL_FOREIGN on the fi

- [the CONDITION reproduced, the RACE did not](condition-reproduced-race-did-not.md) ⭐⭐ an end-to-end green after a race fix can be VACUOUS — the fixed path never ran, so the green is evidence about the LADDER, not the fix. Register the non-reproduction 
- [duplicate work's population is PROCESSES, not code paths](duplicate-work-population-is-PROCESSES-not-code-paths.md) ⭐⭐ a per-process claim cannot exclude a SIBLING process; count distinct pids emitting the event before theorizing re-entrancy. Measured: 
- [read the OTHER leg's GREENS, not just its red](read-the-other-legs-GREENS-not-just-its-red.md) ⭐⭐ the peer job's PASSING rungs refuted my failing rung's whole premise — a green whose predicate has ONE producer in the product proves what already happen
- [an ANTI-ORACLE refusal is opaque to the TEST too](anti-oracle-refusal-is-opaque-to-the-test-too.md) ⭐⭐ one token for unknown/expired/consumed/rate-limited ⇒ the red names nothing; enumerate the refusal's AUTHORING SITES and refute preconditions agains
- [the BARRIER must be the fact you ASSERT](barrier-must-be-the-fact-you-assert.md) ⭐⭐ wait on EXISTENCE + assert a LATER-written field = a snapshot taken 3 steps upstream of the write; deadline cannot help, green is luck, and the "OK: converged" line prin

- [in-flight run logs: CLI refuses, raw jobs endpoint SERVES](in-flight-run-logs-are-gated-read-steps-and-annotations.md) ⭐⭐ `gh run view --log-failed` refuses mid-run even for a CONCLUDED job — that is the CLI, not availability; `gh api .../actions/jobs
- [worktree-remove partial failure reads total](worktree-remove-partial-failure-reads-total.md) content already gone, only the dir ENTRY pinned — ls FIRST, then rmdir+prune, never a blind retry (deployah testimony 2026-08-19).
- [branch -d names the CURRENT HEAD](branch-d-merged-question-names-current-head.md) shared checkout on another lane ⇒ 'not fully merged' is an artifact; merged-ness question must NAME its ref (merge-base --is-ancestor vs origin/main) (deployah testimony 202
