Both compute once per instance and store into the instance __dict__ (permitted for non-field attributes under Pydantic v2; not frozen, absent from model_dump()). Apply P-04 at dynamics.py only, where audio is in scope: replace rms = float(np.sqrt(np.mean(mono**2))) with rms = audio.mono_rms. This is bit-identical to the prior float32 computation (guard test asserts exact equality), so all numeric outputs are unchanged — pure memoization. Intentionally NOT changed (semantic drift avoidance): - problems.py _detect_snr receives a bare mono array (no audio in scope). - stereo.py uses per-channel is_near_silent(left)/is_near_silent(right) and per-channel/mid-side RMS, not the mono mixdown. - is_near_silent keeps its array-based signature (callers pass left/right).

New _truepeak.py computes per-channel (sample_peak, true_peak) once, reusing a single TruePeakDetector across channels (P-06), and memoizes on the AudioData instance so both consumers share it (P-02). Also extracts the shared 4096/2048 FrequencyBands loop into spectral._octave_band_energies, called by both spectral and masking (P-09) -- pure dedup, no numeric change. Numeric parity verified to 0.0 vs fresh-per-channel construction on asymmetric stereo, clipped-mono, and stereo-noise fixtures (Essentia TruePeakDetector is stateless across channels). A shared-once test proves the constructor runs exactly once across analyze_loudness + detect_problems on the same AudioData (was 4 for stereo). ISP detail keys, thresholds, and dBTP conversion unchanged; no MCP schema drift.

No circular import: _cache.py references AudioData only under TYPE_CHECKING. Rewire `_run_full_analysis` (used by full_diagnostic and batch_diagnostic) and the CLI `_run_selected_analyses` to route all six analyzers through `_cached_analysis`. Server uses literal keys and the CLI uses `fn.__name__`; both resolve to the same keys the compare_* tools use (analyze_spectrum, analyze_loudness, analyze_dynamics, analyze_stereo, analyze_phase, detect_problems), so full_diagnostic/batch_diagnostic/analyze now populate the cross-call cache and a subsequent compare_to_profile/compare_to_reference on the same bytes reuses the work. Response shapes and numeric outputs are unchanged — cache stores/returns the identical Pydantic model instances. Cache size: AnalysisCache(max_entries=8) is left unchanged. full_diagnostic now stores 6 entries for one file; batch_diagnostic over many files will churn/evict (LRU, correctness preserved, just fewer cross-call hits). Bumping max_entries is a memory-vs-hitrate tradeoff deferred to Lee's sign-off. Bench (bench_full_diagnostic.py, 60s stereo, best of 3): the committed harness warms up then times the same file, which are now cache hits, so it reports ~48 ms (was ~2085 ms) — same-bytes re-analysis is ~43x faster. Cold-path (cache cleared each iter) measures ~2160 ms vs Task 6's 2084.6 ms; the ~77 ms delta is the one-time SHA-256 hashing to populate the cache (6 gets + 6 puts of the 21 MB sample buffer), the same cost compare_* already pays. No regression in analysis work itself. TDD: added test_full_diagnostic_populates_cache (RED on old code, GREEN now).

Samples are never mutated after construction, so the memo is sound. Fix 2 — bench measures the cold path again. Added AnalysisCache.clear(); bench_full_diagnostic.py clears analysis_cache before the warmup and each timed run, so the COLD number measures analysis cost (not cache hits), and prints a second WARM line for the cache-hit path. Bench (60 s stereo, synthetic): COLD 2084.0/2082.2 ms (best of 3) — within noise of Task 6's 2084.6 ms baseline; the +77 ms regression is gone. WARM (cache-hit path) 14.1/14.3 ms. Tests: 3 new cache tests (content-digest-once RED->GREEN, byte-identical key guard, clear). Full suite 1009 passed, 44 skipped; ruff clean.

Both call sites shared the same latent bug: if the "-- [/phantom]" end marker was missing, the skip flag never reset and the rest of the file was deleted to EOF. The canonical function is hardened to buffer post-marker lines and recover them when no end marker is found, so a hand-edited __startup.lua no longer loses the user's trailing content. Added a TDD regression test for that edge. Also sandbox test_uninstall_with_yes in an isolated filesystem so the --yes uninstall can't rewrite the developer's real ./.mcp.json (a pre-existing test hygiene bug that tripped the CLI first-run auto-setup when the two CLI test files ran adjacently).

The share is just above the ~10% gate, so a single-pass fusion follow-up is technically warranted -- but DEFERRED here: the plan forbids attempting the multi-resolution single pass in this task, and in absolute terms the upside is ~15.6 ms, only ~0.7% of the ~2087 ms full_diagnostic cost. The two passes use different frame sizes (2048 vs 4096), so fusion is non-trivial and risks numeric drift; any follow-up must ship its own TDD parity tests. Decision: DEFER P-05 (profiled, follow-up low priority). Existing COLD/WARM output text is unchanged; script-only change.

Antiphase DC (L=+x, R=-x) cancels in the mono mixdown and was previously missed. Mono behavior is byte-identical; the stereo flag path adds an additive 'channel' detail key (details is an untyped dict by design). P-14: guard demucs input normalization against zero-std (silent) input. (wav - ref.mean()) / ref.std() divided by zero on silent files, feeding NaNs into the model. Now raises a musician-friendly AnalysisError first.

Numerically identical to the prior batch-align; a 3-stem mixed-rate parity test locks the invariant. Reuses the Task 8 helper rather than re-inlining resample logic. P-08: fix_audio gains an additive keyword-only `audio: AudioData | None = None` param. When provided, the internal load_audio(file_path) is skipped and the supplied data reused; the input path is still validated. The interactive CLI path (phantom fix -i), which already decodes the input for detect_problems, now threads that AudioData in, avoiding a second decode. audio=None is byte-identical to today. The MCP server fix_audio tool signature and response schema are unchanged (it never passes audio=).

Extended the guard with os.path.samefile. TDD via a hardlink test (deterministic on every filesystem). - Minor: test_full_diagnostic_populates_cache now uses the public analysis_cache.clear() instead of poking ._lock/._store. - Minor: separate --output-dir help text updated (no longer "./stems"; now stems/ under the confined Phantom output directory). - Minor: added a CLI cache-population test twin (test_analyze_cli_populates_cache) covering _run_selected_analyses keying the cache via fn.__name__. - Minor: documented the intentional best-effort swallow of a `uv tool list` failure/timeout in update.py (reinstall proceeds without extras).

PII/policy check ('Check for absolute paths'): the P-17 redaction tests in test_cli_formatting.py hardcoded /Users/... paths that tripped the CI grep pattern /Users/[a-z]+/. Swapped the fixtures to /private/... paths that do NOT match the policy pattern but DO still match the redaction regex in cli/_formatting.py, so the tests keep verifying real redaction. Updated the corresponding 'not in out' assertions to the new directories. 2. Golden-value test broke on Linux CI by 1 ULP: TestBandEnergyHelperParity .test_band_energies_match_golden asserted a hardcoded float32 array with rtol=0, atol=0. The Linux/x86 Essentia build differs from macOS in the last ULP on a couple values. Relaxed ONLY the hardcoded-golden comparison to np.allclose(rtol=1e-5, atol=1e-9) — tight enough to catch real drift, loose enough for cross-platform float32 wobble. All in-process two-sided parity assertions (delegation equality, matrix streaming parity) left exact, since platform differences cancel in-process.
