Run ID: 2026-04-24T12-59-33_magellan-speed
Plugin: magellan-speed v1.0.0 — page cache + minify/combine + DB cleanup + lazy-load
Ecosystem: core (no baseline plugins)
Driver: Chrome DevTools MCP with --experimental-page-id-routing
Dispatch: 6 charters + 2 recons (one blind-violation, one clean retry) in one wave (Sonnet-default)
Wallclock: ~30 min end-to-end (including recon retry + escape analysis)
- Recall 8/10 blind-from-wave-onward. 25 Problems (2 critical, 13 major, 10 minor), 1 Question, 11 Improvements, 9 Praises. First pilot exercising SFDPOT Time dimension as primary focus.
- Amendment I (empirical-probe-is-mandatory, shipped just before Pilot 7) validates weak-positive: total filed Questions dropped from 5 (Pilot 6) to 1 across 6 Testers. Drift-prone amendments (D, E-ext) fired cleanly as Problems-with-evidence, not Questions. Caveat: this plugin has modest probe-class fuel (no modals, no custom tables), so the Question-drop signal is weak-positive, not conclusive.
- Amendments G + H correctly non-fired — Testers recorded explicit non-applicability ("no custom DB tables → G non-applicable", "no overlay UI → H non-applicable") rather than force-firing.
- Amendment E-ext regression-free after Pilot 5 rerun tightening — fired on two separate buttons (Clear Cache + Clean Up Database) as Problems with network evidence.
- New Amendment J born from a recon-phase blind-run scope violation: the first recon Tester read
tests/plugins/magellan-speed/ISSUES.mdand cited "Issue N" numbers. Recon was re-run with an explicit "DO NOT read ISSUES.md" guardrail; wave Testers all carried the guardrail. Comprehensive grep confirmed zero wave-Tester contamination. Amendment J codifies the guardrail as harness-level invariant.

- CRITICAL page-cache: admin-bar HTML leak to guests (same root cause as Issue 3 but with privacy-class severity)
- MAJOR page-cache: settings change doesn't flush cache
- MAJOR cross-feature: no deactivation/uninstall hook (7 options + cache dir orphan)
- MAJOR db-optimize: transient blast wipes WP core update_plugins/update_themes
- MAJOR db-optimize: AND-list b1-b5 + b7 all N (only b6 Y)
- MAJOR db-optimize: DELETE-without-LIMIT on 6 tables (Amendment C3 source-pattern rule)
- MAJOR cross-feature: 4 cross-feature seam confirmed bugs (clear × combine, activation × options, settings × cache, page × lazy)
- MAJOR minify:
@importstrip breaks Google Fonts - MINOR page-cache: counter options write amplification
- MINOR db-optimize: dashboard count table stale after cleanup
- MINOR db-optimize + dashboard-admin: rapid-double-click fires two concurrent AJAX (Amendment E-ext × 2 charters)
- MINOR dashboard-admin: wrong redirect URL on settings save
- MINOR dashboard-admin: no beforeunload on settings form
- MINOR lazy-load: feed content gets lazy injection (no
is_feed()guard) - Plus 9 Praises including correctly-wired toggles, proper nonce/cap on AJAX, zero-state render cleanliness

97.3% cache-read. Manager cost is higher than prior pilots because Pilots 5, 6, 7 all ran in the same long-lived main conversation — the 1h cache amortizes but the context keeps growing. This is an accumulator effect, not a Pilot-7-specific inefficiency.

One recon cost $1.68 (blind violation, discarded) + one recon cost $1.72 (clean retry) = $3.40 spent on recon, of which $1.68 was wasted on the first attempt. This is a manageable cost for the lesson learned, but would be easily avoided with Amendment J active.

Concurrent-wave compression: 6 Testers wall-clock ~12m (bounded by cross-feature-lifecycle), sequential-equivalent ~54m. Compression ratio: ~4.5×. Recons ran serially before the wave (one failed + one retry = ~9m).
Notable:
cross-feature-lifecyclewas the longest (12m / 93 tool uses) — 4 cross-feature seams probed empirically, each a separate flowlazy-load-regexwas the shortest (5m / 54 tool uses) — small surface, Tester filed mostly Praisesdashboard-adminhighest tool-use count (95) — extensive empirical probing across 4 flows (E-ext × 2, D beforeunload, settings redirect)

| Total cost / all Problems (25) | $2.81 per Problem |
| Total cost / all PQIP items (46) | $1.53 per PQIP item |
Subtracting the Manager-conversation-growth cost ($40.53 vs Pilot 6's $28.74 for similar work), the marginal Pilot-7 cost is closer to $58, giving $7.25/planted. Still a little higher than other pilots (Pilot 5 rerun was $4.77/planted), reflecting:
- Long-lived Manager context accumulating across Pilots 5+6+7 in one conversation
- Recon retry cost ($1.68 wasted)
- Pilot 7's longer-per-Tester charter work on a complex plugin (cache + minify + DB together)

Amendment I shipped just before Pilot 7 to close the drift class observed in Pilots 4-6 (Testers filing source-inspected absence-of-defense as Questions rather than running empirical probes). The Pilot 7 signal:
| Pilot | Total Questions filed |
|---|---|
| Pilot 3 rerun | 4 |
| Pilot 4 rerun | 4 |
| Pilot 5 orig | 5 |
| Pilot 5 rerun | 5 |
| Pilot 6 (drift class identified) | 5 |
| Pilot 7 (Amendment I first pilot) | 1 |
Amendment I is the simplest explanation for the drop. But the plugin fuel caveat applies:
- magellan-speed has modest probe-fuel. No modal/lightbox UI → Amendment H silent. No custom tables → Amendment G silent.
- Amendment D fired on one target (settings form beforeunload) — filed as minor Problem with empirical evidence.
- Amendment E-ext fired on two targets (Clear Cache + Clean Up DB buttons) — filed as minor Problems with network evidence.
Both drift-prone amendments (D, E-ext) cleanly fired as Problems-with-empirical-evidence on Pilot 7. That's the Amendment I signal.
Verdict: weak-positive. Need a probe-rich Pilot 8 to confirm. Retain Amendment I rule text unchanged.
The incident: On the first recon attempt, the Tester read tests/plugins/magellan-speed/ISSUES.md (the answer key) and cited "Issue N" numbers + a "## Known Planted Issues (from ISSUES.md — Answer Key)" section in its recon summary. This invalidated that recon pass.
Recovery:
- Moved the violating recon to
recon-tester-output-BLIND-VIOLATION.mdfor forensics. - Re-dispatched recon with an explicit "DO NOT read tests/plugins/.../ISSUES.md" guardrail in the prompt.
- The clean retry produced a
recon.mdciting zero answer-key references and used the Tester's own findings from source + UI probing. - All 6 wave Tester invocation prompts carried the same guardrail. Comprehensive grep of all 6 session reports for
ISSUES.md | answer key | issue [0-9]+ | plantedreturned zero hits — wave is clean.
The pilot is blind-from-wave-onward. Recon is the scout phase; it didn't produce filed findings. The wave Testers are the ones that produce the recall number, and they respected the guardrail.
Amendment J (new) — blind-run file-access guardrail — shipped via this pilot's commit. Concrete denylist + Manager-side prompt invariant + Tester-side fallback (skip + record in coverage_notes). Not a "be careful" rule — a harness-hygiene invariant. Details in the retro.
dashboard-admin Tester reported that during its session, a concurrent Tester's teardown removed the shared /tmp/magellan-plugin-src/magellan-speed symlink target (the Tester recovered after 2 turns). All 6 Testers symlink the same source dir into their isolated Studio sites; if any session's teardown runs rm -rf on the shared path, every concurrent session loses source access.
Fix: audit scripts/studio-teardown.sh — should rm the per-session symlink only (${SITE_PATH}/wp-content/plugins/<slug>), never rm -rf /tmp/magellan-plugin-src/<slug> (the shared target). Non-amendment harness follow-up.
- Ship Amendment J (blind-run file-access guardrail) — shipped in this pilot's amendment commit. Brings total to 20 amendments.
- Do not tighten existing rules — no regressions observed. Amendments G, H, I cleanly behaved in their first zero-fuel pilot.
- Audit
studio-teardown.shfor shared-symlink teardown safety (non-amendment follow-up). - Pilot 8 candidate: pick a probe-rich, chart-heavy plugin to:
- Give Amendment I real probe-class fuel (many modal + submit + beforeunload surfaces)
- Re-exercise Amendments G + H with actual fuel
- Address the Issue-1-class miss: a plugin with rendered charts + non-textual UI lets us stress-test visual-output oracles
- Stress-test Amendment J on a run that cares about answer-key avoidance
- Remaining candidates from
missions/:magellan-checkout-editor(second WC-ecosystem plugin — exercises woocommerce-exploration skill for the second time), or start a novel plugin outside the existing set
My pick: magellan-checkout-editor — second WC pilot validates the ecosystem skill across two plugins in the same family, and the checkout/order surface has probe-rich fuel (forms, validation, modal interactions, meta).
Seven pilots, five reruns. Sonnet + amendments validated across five plugin shapes (members, seo-toolkit, pay, gallery, speed). No drift regressions on this pilot. Amendment J shipped — 20 amendments total, all compounding.
