# CCD three-part reset: final result boundary

## Direct-dq facts

Two schema-v3, three-role, 450-control acquisitions completed with the corrected Legacy `q/U0` decoder and exact acquisition-relative timelines:

- Kármán `karman_re100`: field interval 2000; retain exactly the 120 snapshots with relative lattice step `>120000` (122000–360000). The weighted vector-RMS of `e_target = q_ctl - q_target` is `0.15965716015602738`. Algebraic closure `e_target = dq_ctl - dq_tar` has maximum absolute residual `9.5367431640625e-07`.
- Illusion `illusion_1.0L`: field interval 1250; retain exactly the 144 snapshots with relative lattice step `>90000` (91250–270000). The weighted vector-RMS target error is `0.08031177071338107`. Maximum closure residual is `1.7881393432617188e-07`.

Both results preserve full-resolution instantaneous role and difference fields, means, solver-mask intersection, exact x/D=35/40/45 profiles, mask-aware vorticity, and declared prefix/suffix convergence diagnostics. The 90/120 Kármán and 108/144 Illusion windows show decreasing mean-field deviations, but one trajectory cannot provide independent-realization uncertainty or by itself prove asymptotic convergence.

These are same-time direct differences. They are not phase-conditioned results. `dq_ctl` and `dq_tar` share `-q_blk`; similarity between them is descriptive and is not causal mechanism evidence. The momentum-flux quantity is explicitly an incomplete proxy, not a complete momentum balance.

Authoritative immutable results:

- `evidence/direct-dq-karman-burn120000/`
- `evidence/direct-dq-illusion-authorized-burn90000/`

A validated reload depends on the immutable live acquisition roots recorded by absolute path in each result; the result directories are not standalone portable evidence.

## Original CCD capability

`original_ccd/` implements the original full-field Lyu operator `A = P U†/(N sqrt(LQ))`, weighted modes, exact lag/block handling, coefficients, lag functions, and rank-selected reconstruction/residual. It does not use preliminary POD, row standardization, or whitening. The published-scale synthetic derivation and production-reference tests pass.

The frozen real-case observable decision was executed for Kármán only. The authoritative Q=1, tau=0 result is `evidence/real-ccd-karman-q1-tau0-burn120000-v1/` (manifest SHA-256 `97d5cb300d642295bd3dffedd85d940fde06c8cc1c236fade390db78c3e3810e`). Its singular values are `0.14676751183519246`, `0.05920814023903697`, and `0.0063884442355860915`; squared cross-correlation strengths are `0.02154070253029336`, `0.003505603870565469`, and `0.00004081221975119316`. The three action means (front/upper/lower, native units) are `-0.004750394590640402`, `-0.0417400509895136`, and `0.03969304291531443`. The result has numerical rank 3, no degenerate singular blocks, modes shape `(1299184, 3)`, coefficients shape `(3, 120)`, and weighted relative residuals `0.7823805118116768`, `0.4698397615223296`, `0.45542496362972573` after complete blocks 1, 2, 3. Fresh-process live-provenance reload and essential identity recomputation passed. The singular values are cross-correlation strengths, not field energy, explained variance, canonical coefficients, causal effects, mechanism evidence, uncertainty, or a CCD-versus-POD comparison. Illusion CCD was not run and requires a separate user authorization decision.


## Karman figure subset

The deterministic CPU artifact-derived package is `evidence/real-ccd-karman-figures-v1/`. It uses only the public verified real-CCD loader, retains the 1280 x 512 grid without downsampling, and publishes PNG/PDF figures plus quantitative Markdown/JSON interpretation. Selected reconstruction snapshots are acquisition-relative lattice steps 122000, 242000, and 360000; no full MxN reconstruction is persisted. The governing two-case figures review remains partial/in progress because Illusion was not run and awaits user authorization. The unique next entry remains that authorization decision.

## Kármán dynamic-increment final publication

The accepted-plan final stage is complete at `data/karman-dynamic/karman-dynamic-v1-production/publication-v2/`. Six artifact-only PNG/PDF figure pairs and concise `RESULTS.json`/`RESULTS.md` report the four-role mean performance decomposition, DRL-versus-constant 10-bin phase statistics and centered phase difference, temporal negative-lag CCD spectrum/modes/left lag functions/common-support sensitivity, and an explicit phase-domain **DOWNGRADE**. Zero appears only in mean statistics; no zero phase figure or claim exists because its phase gate failed.

Mean target errors are zero `0.2177701`, constant mean `0.1680192`, and DRL `0.1599946`. Thus zero-to-constant reduces error by `0.0497509`; constant-to-DRL contributes a further `0.00802465`, about `13.9%` of the total zero-to-DRL mean-error reduction. Constant/DRL cycle-mean 10-bin phase target errors are `0.2126461`/`0.1821272`. Temporal leading strengths are `2.77997e-3`, `1.91480e-5`, and `1.32484e-7`; common-support leading-three principal cosines remain at least `0.999998746`, while native support is sample-support-sensitive. Phase-domain CCD remains DOWNGRADE because first-harmonic rank is 2 instead of primary rank 3.

Strict code/science/claim review passed after one allowed remediation: `publication-v1` omitted the target bar despite the four-role requirement; immutable `publication-v2` fixes it. Dense fields were not deleted role-by-role: DRL is required for independent temporal recomputation, constant_mean and target for independent source-level mean/statistics recomputation, and zero has no compact field replacement after its failed phase gate. Focused Kármán tests: 26 passed; full active CCD suite: 178 passed; changed-file lints and scoped diff whitespace checks passed; old real-CCD/direct-dq loaders remained isolated from the publication process.
