19
+
20
+ **Brief:** `/Users/Zer0pa/orchestration-state/PROMPT_LANE_AGENT_PRODUCT_PAGE_2026-05-09.md` + `/Users/Zer0pa/Desktop/xr-product-page-build/FPO_DISPATCH_BRIEF_PRODUCT_PAGE_2026-05-09.md` §A Slot 29 (line 659-676), §B.1 row (line 769), §C.2 ZPE-Bio note (line 870). Reference standard: live XR prototype at `127.0.0.1:8765/`. Lane status: **GO**, KEEP carried headline `ECG with a fidelity contract.`, current-reality voice.
21
+
22
+ **Build target:** `/Users/Zer0pa/Desktop/zpe-bio-product-page-build/index.html` (74,626 bytes after polish). Built from the locked XR template by atomic regex-anchored swaps; no shared CSS / JS / scaffold edits.
23
+
24
+ **Lane-owned cells written (12 cells per §1 truth contract):**
25
+ 1. **00 Hero:** b-id `00 · ZPE-BIO · ECG CODEC` + `LIVE LANE · 113000Z`. Headline retained verbatim from landing card per §B.1 KEEP call: `ECG with a <span class="accent">fidelity contract.</span>` (4 words, accent on the wedge phrase). Sublabel per prompt §4.3: `PyPI v0.2.1 · github.com/Zer0pa/ZPE-Bio · A clinical-mode ECG codec`. Body lede 50 words, both load-bearing scalars (mean PRD 1.12% + mean CR 1.32×) packed inline, contract-split surfaced ("logs across the same Python and Rust cores but reaches max PRD 5.29% — outside the contract, disclosed not buried"). No duplication with 05.0.
26
+ 2. **04 INSIGHT:** `An ECG codec under a stated <span class="accent">clinical fidelity contract.</span>` — 9 words; verbatim from §A "04 Insight bound."
27
+ 3. **05.0 CURRENT TECH:** 31 words. Names the incumbent posture without strawmanning ("Most ECG codecs report mean compression and round-trip integrity, but bury the worst case in supplementary tables. They rarely publish a fidelity contract the codec is allowed to visibly fail.").
28
+ 4. **05.1 OUR TECH:** 35 words. Names the wedge at protocol level ("...published PRD ≤ 2.32% clinical contract. The boundary case — PTB-XL max PRD 5.29% — renders on the same chart as the pass cases, in gray. Not buried.").
29
+ 5. **05.2 BENCHMARKS:** 4 mini-metrics (`MIT-BIH 48/48`, `Mean PRD 1.12%`, `PTB-XL 100/100`, `Contract 2.32%`) + 3 mini-bars (`MIT mean` focus, `MIT max` subordinate, `PTB max` gray-dim — visually the longest bar, marking the contract excursion as the visual punctum) + mini-note naming all four corpora.
30
+ 6. **06 MEASUREMENT:** `PRD measured on four named corpora, against <span class="accent">a published clinical contract.</span>` (12 words).
31
+ 7. **06.1 COMPARATIVE PERFORMANCE:** 4 rows per §A — `MIT-BIH · mean` focus white at 1.12%, `NSTDB · max` 1.96% faint, `EDB · max` 4.34% dim, `PTB-XL · max` 5.29% dim with `OUT` suffix. Caption names all four corpora + record counts + contract `PRD ≤ 2.32%` + the §C.2-mandated "PTB-XL excursion logged, not buried."
32
+ 8. **07 row label:** `KEY METRICS · MIT-BIH · PTB-XL · CONTRACT`.
33
+ 9. **07.1–07.5 KEY METRICS** (exactly 5, all §B-defensible): `MIT-BIH integrity 48/48`, `Mean CR 1.32×`, `PTB-XL integrity 100/100`, `PRD contract 2.32%`, `Mean PRD 1.12%` — no `null` cards needed; no fabricated fifth metric.
34
+ 10. **08 DETERMINISM:** `Same ECG strip, <span class="accent">same bytes, same PRD</span> across Python and Rust.` (11 words).
35
+ 11. **08.1 WHAT DETERMINISTIC MEANS:** 51 words. Explains the unit of bit-exactness across MIT-BIH/NSTDB/EDB; names PTB-XL's deterministic-but-out-of-contract status; names CI parity-gating.
36
+ 12. **08.2 FIDELITY GAP (NON-NEGOTIABLE):** 50 words. Carries the §A non-claim verbatim — `Cardiologist-equivalence at κ ≥ 0.85 remains PENDING. PTB-XL 100/100 integrity is logged but its max PRD reaches 5.29% — outside the 2.32% clinical contract. No regulatory clearance, no medical-device claim, no EEG, and no wearable scope are claimed today.` Mono, no amber, no recoloring, no relocation.
37
+
38
+ **External cells preserved as placeholder per §0.4 + §1 + agent handoff (operator-supplied; lane agent does not invent):**
39
+ - Cell #2 hero diagram → **black placeholder at 572×534** per §C.4 (only ZPE-XR has supplied asset this wave).
40
+ - 01 GAP / 02 MARKETS / 03 VALUE → all marked `EXTERNAL · OPERATOR PENDING`; row pinned to LAW 306px via inline `min-height` so the placeholder row holds reference rhythm.
41
+ - 09 / 09.1 / 09.2 / 09.3 → marked `EXTERNAL · OPERATOR PENDING`; row pinned to LAW 240px via `grid-auto-rows: minmax(240px, auto)`.
42
+ - 09.4 / 09.5 / 09.6 / 09.7 / 09.8 → all five unlock cards marked `EXTERNAL · OPERATOR PENDING`; row pinned to LAW 264px via `grid-auto-rows: minmax(264px, auto)`.
43

62

63
+ **18/18 cells within the ±15% LAW tolerance** (template rules §4 + §1 governing law). 11/18 within ±0.3%. The +10% drift on the 04/05.x row driven by JetBrains Mono char-width difference of ECG-domain prose vs XR's domain prose at identical word counts; well inside tolerance, no clipping. The two material drifts identified on the first build (01/02/03 row at −21.5%, 09.4 unlock at −21.6%) were closed with `min-height` / `grid-auto-rows` pins on the placeholder rows — no shared CSS edits, no inline-rule additions to non-placeholder cells.
64

65
+ **Visual-QA receipts (`/Users/Zer0pa/Desktop/zpe-bio-product-page-build/`):**
66
+ - `product-page-full-1440.png` — full-page screenshot at 1440px
67
+ - `product-page-top-crop.png` — hero + 01/02/03 row

70
+ - `product-page-mobile-414.png` — 414px viewport, single-column collapse
71
+ - `product-page-audit.json` — full machine-readable audit
72
+
73
+ **Verified (template rules §13 + §C.6):**
74
+ - Console errors: **0**
75
+ - Pretext: **active** (`document.documentElement.dataset.pretext === 'active'`)
76
+ - Non-live green: **0** (only allowed green is `.b-id .live` LIVE LANE stamp; no supplied diagram, so no diagram-pixel exemption needed)
77
+ - All 12 external slots blank/placeholder-marked (01 / 02 / 03 / 09 / 09.1 / 09.2 / 09.3 / 09.4 / 09.5 / 09.6 / 09.7 / 09.8)
78
+ - Stale-label scan against XR vocabulary tokens (`ContactPose`, `Ultraleap`, `Photon proxy`, `MPJPE`, `headset`, `Hand tracking`, `26-byte envelope`, `two-hand`, `joints each`, `ZPE-XR` outside shared nav chrome): **0 occurrences**
79
+ - Pretext-tight clipping: **0/total** on every measured target (`.b-title h2`, `.b-statement-card h2`, `.b-unlock .ttl`, `.b-prose p`, `.b-unlock .body`)
80
+ - Mobile fold: lane-body collapses to single column at 414px; metric strip stacks above viz; all 29 cells legible; no clipping
81
+
82
+ **Truth basis:** §A `reports/ZPE-Bio.md:29-46,56,89` + `falsification/ZPE-Bio.md:19-50` (Slot 29 truth envelope) · §B "Final headline call: KEEP carried `ECG with a fidelity contract.`" · §C.2 "surface PTB-XL out-of-contract excursion in cell 06.1 or cell 07 (not blocker-only); cell 06.1 visible split MIT-BIH focus vs PTB-XL `5.29%` gray captioned outside 2.32% clinical contract; cell 08.2 retains cardiologist-κ pending and no-regulatory fence" — honored on the live render at three levels (05.2 mini-bars, 06.1 main comparative, 08.2 honest blocker).
83
+
84
+ **Diff-scope assertion:** edits confined to a single new file at `/Users/Zer0pa/Desktop/zpe-bio-product-page-build/index.html`, generated by atomic regex-anchored swaps from the locked XR template (`/Users/Zer0pa/Desktop/xr-product-page-build/index.html`) via three Python build scripts (`/tmp/zpe-bio-build.py`, `/tmp/zpe-bio-pin-heights.py`, `/tmp/zpe-bio-polish.py`). No shared template edits, no astro/site-registry edits, no landing-rd-v3 edits, no repo edits this round.
85
+
86
+ **Open (operator pickup):**
87
+ - External cell content: 01 GAP, 02 MARKETS, 03 VALUE, 09 POSSIBILITY, 09.1 AMBITION, 09.2 LIVE PROBE, 09.3 LIVE WORKSTREAM, 09.4–09.8 unlock cards (12 cells total) — operator-supplied per agent handoff §3 + §C.4.
88
+ - Hero diagram cell #2 — operator-supplied codec-mechanics asset (current state: pure-black 572×534 placeholder per §C.4 — correct contractual state).
89
+ - Repo-side fixes per §A line 675 (clinical contract precision `2.32%` rounded display vs `2.324893%` low-level proof artifact; refresh stale embedded README commit SHA `b57bd19f` vs main `ae275189`) — repo-team scope, not lane-agent.
90
+
91
+ **Status:** product page **drafted, rendered, audited, parity-checked**; all visual-QA gates green. Awaiting operator review + external-data dispatch.

95
+ ### 2026-05-08 · Landing-card Wave 2 · round-3 verify-only + screenshot receipts (Corridor Agent)
96
+
97
+ **Brief:** round-3 dispatch (the brief that adds the smart-outsider headline test and the explicit no-internal-shorthand list).
98
+
99
+ **Wave-2 class for this lane:** still **WAVE2-FIX, P2** — the Wave-2 brief at `LANDING_CARD_WAVE2_CENTRAL_DISPATCH_BRIEF_2026-05-08.md` was inspected this round; ZPE-Bio's rows (§A 380-385, §B 476, §C.3 740-744, §C.4 row 792, §D row 881) are unchanged from the previous Wave-2 round. The fix described in those rows landed in the prior corridor pass (entry below).
100
+
101
+ **Round-3 smart-outsider headline test:** Current headline is `ECG with a fidelity contract.` (4 words / 29 chars; accent on `fidelity contract.`). Applied the round-3 step 2a: would a smart outsider know what this does, what it aims to do, or what failed?
102
+ - "ECG" → cardiac signal data (well-known abbreviation).
103
+ - "fidelity contract" → "fidelity" is plain English (signal/quality fidelity, audio/video fidelity); "contract" is plain English (a binding agreement). The compound reads as "a binding fidelity guarantee."
104
+ - Net proposition for a smart non-specialist outsider: "this is an ECG codec that contractually guarantees signal fidelity." That lands without needing any Zer0pa-internal context.
105
+ - Comparison to the round-3 brief's red-flag list (`closed chain` / `owned pending` / `intake dossier` / `structural audit` / `authority packet` / `declared ground` / `each exact`): "fidelity contract" is not in that family. Each red-flag noun pair is a process- or governance-internal label with no inferable proposition; "fidelity contract" is a compound where both words land in plain English and combine to a clear engineering proposition.
106
+ - Wave-2 §C.4 row 792 already rated this headline "Hits". R5 (flattery-as-freedom) says do not redesign for taste.
107
+ - **Decision:** retain. No headline edit this round.
108
+
109
+ **Block touched this round:** none. **Files changed this round:** none. The Wave-2 round-1 edits (body paragraph + viz redesign + viz trim) remain in place.
110
+
111
+ **Truth basis used (re-verified this round):**
112
+ - Live-page render at `http://127.0.0.1:4631/landing-rd-v3/` returns HTTP 200; pulled and grep-checked the rendered ZPE-Bio article — 20-of-20 truth + scaffold tokens present (data-status="populated", contract-split prose `holds the contract` / `outside that contract`, viz contract envelope label `PRD 2.32% CLINICAL CONTRACT`, breach circle at `cx="334"`, breach callout `PTB-XL · MAX PRD 5.29%`, viz-cap `CONTRACT HOLDS, PTB-XL EXCURSION DISCLOSED`, blocker κ ≥ 0.85 PENDING + non-claim list, CTA → `https://github.com/Zer0pa/ZPE-Bio`, all 4 immutable corner spans, all 4 viz corner spans, `class="svg-soft"`, `data-count` animations on 1.12 + 1.32, MIT-BIH 48/48 + PTB-XL 100/100 metric values).
113
+ - Repo HEAD still `ae2751893dcc`. `gh repo edit` description and topic-prune from Wave 1 verified intact (12-topic list, no `eeg`/`wearable`/`medical-devices`/`electrophysiology`/`digital-health`/`lossless-compression`/`machine-learning`/`artificial-intelligence`/`embedded-systems`).
114
+
115
+ **Desktop block-in-context screenshot:** captured at `/tmp/zpebio-desktop-context.png` (1440×900 viewport, deviceScaleFactor=2, full-page screenshot clipped to ~1 row above + ~1 row below the ZPE-Bio article). Per-block also at `/tmp/zpebio-desktop-block.png`.
116
+
117
+ **Mobile block-in-context screenshot:** captured at `/tmp/zpebio-mobile-context.png` (414×900 viewport). Per-block at `/tmp/zpebio-mobile-block.png`. Lane-body single-column collapse confirmed per §C.5; metric strip stacks above viz; all four metric values render to final state (1.12 % / 1.32×); breach point + corpus boundary ticks + footer "PTB-XL EXCURSION DISCLOSED" all legible at mobile width.
118
+
119
+ **Benchmark-footprint and style compliance (measured this round on the live render):**
120
+ - Block bounding box (desktop, 1440px viewport): **677 × 673 px**. Width matches the grid `span 6` proportion at this viewport (~563 px at 1200vp scales to ~676 at 1440vp). **Height 673 px sits squarely inside the §C.3 661–676 px benchmark envelope** and well below the 720 px hard ceiling. Card holds grid rhythm against neighbours in the desktop context screenshot.
121
+ - SVG markup: 4,124 bytes — slightly above the 1.8–3.2 KB benchmark and 28 B above the soft 4 KB descriptive guideline ("almost always over-detailed"); below co-rated lanes (IoT 4,986 / Glyph-Engine 5,080 / Diagram 4,746). The bytes are doing the §C.3-mandated visual punctum (PTB-XL out-of-contract excursion above the 2.32% line). Verified visually on the live render: contract envelope dashed, hatched OOC zone over PTB-XL only, breach circle + leader + `PTB-XL · MAX PRD 5.29%` callout all readable at the 250 px column height.
122
+ - Headline: 29 chars / 4 words / accent on last 2 words ending with period — within §C.3 envelope.
123
+ - Body paragraph: 388 chars / 53 words / 4 sentences / 1 `<strong>` — under the 400-char hard ceiling.
124
+ - Honest blocker: ~245 chars / preserves §A non-claim verbatim.
125
+ - Metric rows: exactly 4 (§C.3 hard requirement).
126
+ - Mobile fold: at 414 px viewport the card stacks to 372 × 1125 px single-column; lane-body partition unwinds correctly; all six load-bearing surfaces (headline / body / metrics / viz / blocker / CTA) remain legible; breach point retains visual punctum after horizontal compression of the SVG (preserveAspectRatio="none" warps gracefully).
127
+ - Immutable scaffold tokens (corner spans · head/body/foot triad · metric/viz split · blocker/link pair · `svg-soft` · `data-repo` · `target="_blank" rel="noopener"` · `<span class="num">29</span>` · `<span class="stamp-block portfolio">ENCODING</span>` · `<span class="cat">· ZPE-BIO · ECG CODEC</span>`): all present, all unchanged from Wave-1 scaffold.
128
+
129
+ **Repo / web truth sync this round:** none required. Re-verified Wave-1 G4 (description + topic prune) still in place via `gh api repos/Zer0pa/ZPE-Bio --jq '{description, topics, pushed_at}'`. README HEAD unchanged at `ae2751893dcc`. No new repo-side directive in Wave-2 §B 476 beyond the already-completed R4 topic prune.
130
+
131
+ **Resistance risks checked and not triggered:**
132
+ - **R1 Shape-match design / benchmark-shape mimicry:** card carries lane-specific cargo (PRD ≤ 2.32% contract, MIT-BIH/PTB-XL corpus split, ECG QRS waveform, 5.29% breach point). Removing the data leaves no recognisable benchmark shape.
133
+ - **R2 Rush to green-flag:** verified the live render this round before declaring done; refused to churn the headline despite the round-3 brief's general guidance, because the smart-outsider test passed and Wave-2 §C.4 already rated it "Hits".
134
+ - **R3 Approval via packet quality:** receipts describe what the page actually carries; live-render grep + screenshots are the proof.
135
+ - **R4 Efficiency-as-ownership-fracture:** repo G4 + card body + viz + blocker all verified end-to-end this round, not just card-side.
136
+ - **R5 Flattery-as-freedom:** did not change the headline ("Hits" rating respected, smart-outsider test passed); did not invent metrics; did not soften §A non-claim language; did not redesign approved scaffold elements.
137
+ - **Round-3 step 2a (smart-outsider headline test):** explicitly applied above; result documented; decision documented.
138
+
139
+ **Status:** verify-only. Card content, repo metadata, and live render all hold. Awaiting operator visual review (screenshots above).

143
+ ### 2026-05-08 · Landing-card Wave 2 · slot 29 truth-tightening (Corridor Agent)
144
+
145
+ **Brief:** `/Users/Zer0pa/orchestration-state/LANDING_CARD_WAVE2_CENTRAL_DISPATCH_BRIEF_2026-05-08.md`. Wave-2 class for ZPE-Bio: **WAVE2-FIX, P2** (§A line 380-385; §B line 476; §C.3 line 740-744; §C.4 row 792).
146
+
147
+ **Fix target named:** Wave-1 metric and blocker correctly carried "PTB-XL ... outside the clinical 2.32% contract", but the **human paragraph** said only "boundary disclosed at max PRD 5.29%" — leaving the contract-split entirely on the blocker, and the **viz** marked the boundary as a small triangle rather than the visual punctum. §C.3 directive: "render the **PTB-XL out-of-contract zone visibly** — show the 5.29% PRD region against the 2.32% clinical contract line. The clinical-contract split should be the visual punctum, not a footnote." Repo continuity (G4 description + topic prune) was completed in Wave 1 and verified intact this session — no repo-side action required in Wave 2.
148
+
149
+ **Wave-2 edits — landing card slot 29 (this is the only block touched):**
150
+
151
+ 1. **Body paragraph rewritten** to carry the contract-split in plain prose, not just the blocker.
152
+ - Before: "...bounded clinical-mode contract. **MIT-BIH 48/48 integrity** at mean PRD 1.12% and mean CR 1.32×, with PTB-XL 100/100 integrity and the boundary disclosed at max PRD 5.29%. Python and Rust cores are CI parity-gated. Cardiologist-equivalence and regulatory closure remain out of scope."
153
+ - After: "...PRD ≤ 2.32% clinical contract. **MIT-BIH 48/48 integrity at mean PRD 1.12%** holds the contract; PTB-XL 100/100 integrity is logged but max PRD reaches 5.29% — outside that contract. Python and Rust cores are CI parity-gated. Cardiologist-equivalence and regulatory closure remain out of scope."
154
+ - The CR figure moved off the paragraph and lives only in the metric strip; the paragraph now carries the §C.3-mandated contract surface in three load-bearing words: "holds the contract" / "outside that contract".
155
+ - Length: ~388 chars / 53 words / 4 sentences / 1 `<strong>` span. Inside the 400-char/65-word hard ceiling.
156
+
157
+ 2. **Viz redesigned** so the PTB-XL excursion is the visual punctum, per §C.3.
158
+ - Single-pane ECG flowing left-to-right across four corpus ranges (MITDB | NSTDB | EDB | PTB-XL) with corpus boundary ticks separating them.
159
+ - **Shared 2.32% clinical contract envelope** as a dashed horizontal at y=80 (top) and y=120 (bottom of in-contract band) — labelled "PRD 2.32% CLINICAL CONTRACT" centred at y=76.
160
+ - **Out-of-contract zone** rendered as diagonal hatching above the envelope, scoped only to the PTB-XL range (x=290–378). MIT-BIH/NSTDB/EDB ranges have no hatch — they sit cleanly inside the envelope.
161
+ - **Reconstruction trace** stays inside the envelope across MITDB/NSTDB/EDB and **breaches** at one PTB-XL QRS complex, climbing to a circle marker at (334, 56) — physically piercing the dashed contract line.
162
+ - **Breach callout** "PTB-XL · MAX PRD 5.29%" with leader from the marker to the label.
163
+ - Per-corpus labels under the band (MITDB 48/48 · NSTDB 15/15 · EDB 90/90 · PTB-XL 100/100); footer reads "MEAN PRD 1.12% · CR 1.32x · CI PARITY-GATED" + "EXCURSION ABOVE CONTRACT LINE IN PTB-XL ONLY".
164
+ - Caption: `FIG · CONTRACT HOLDS, PTB-XL EXCURSION DISCLOSED` (48 chars / 50 limit).
165
+
166
+ 3. **Headline accent retained** — Wave-2 §C.4 row 792 rated headline "Hits"; per Resistance-5 (flattery-as-freedom), no churn.
167
+
168
+ 4. **Metric strip retained** — exact §B-defensible four metrics, unchanged from Wave 1; Wave-2 §A confirmed numeric alignment (2.32% rounding acceptable; 2.324893% precision drift is a low-level proof-artifact issue for repo team, not card scope).
169
+
170
+ 5. **Blocker retained** — already carried §A non-claim verbatim; Wave-2 §A flagged only that it was load-bearing alone; with body+viz now surfacing the split, blocker is no longer load-bearing alone.
171
+
172
+ **Truth-basis line:** §A truth envelope (Slot 29: MIT-BIH 48/48, mean PRD 1.115854%, mean CR 1.323; PTB-XL 100/100, max PRD 5.285%; cardiologist κ ≥ 0.85 PENDING; ECG-only scope) + Wave-2 §A line 381-385 fix directive + Wave-2 §C.3 line 740-744 viz directive + ZPE-Bio README sections "Headline metric / Honest blocker / Key Metrics / Verification Status" at HEAD `ae2751893dcc`.
173
+
174
+ **Diff-scope assertion:** Two atomic block-replacements via `/tmp/zpe-bio-card-wave2.py` (full Wave-2 update) and `/tmp/zpe-bio-card-wave2-trim.py` (viz byte trim). Each script enforces `count == 1` regex match against the exact preceding state (`STATUS=POPULATED` + `data-lane="zpe-bio"`) and atomic `os.replace()`. **Edits confined to a single `<article data-lane="zpe-bio">…</article>` block + its `<!-- CARD: -->` comment marker**, by construction. No `data-lane` boundary crossed, no shared CSS / JS / scaffold / page-wrapper / portfolio chip / slot ordering touched.
175
+
176
+ **Benchmark-footprint compliance:**
177
+ - Block size: 6,954 bytes (Wave-1 was 5,653; the 1.3 KB increase is proportionate to the SVG's expanded information job per §C.3 mandate).
178
+ - SVG size: **4,124 bytes**. Slightly above the §C.3 1.8–3.2 KB benchmark envelope and 28 bytes past the soft 4 KB ceiling, but well below the live co-rated lanes (IoT 4,986 / Glyph-Engine 5,080 / Diagram 4,746 — all rated "Approaches" in Wave-2 §C.4). The bytes carry the contract-split visualization the brief explicitly demanded; trimming further would either drop corpus-range markers or kill QRS complex fidelity. Held the line — the viz is information-dense, not over-detailed.
179
+ - Headline: 29 chars / 4 words. Well inside §C.3 envelope.
180
+ - Body paragraph: 388 chars / 53 words / 4 sentences / 1 `<strong>` span. Inside hard ceiling; ~18 chars over the 340–370 target — acceptable for the surfacing job §A demanded.
181
+ - Honest blocker: ~245 chars / preserves §A verbatim.
182
+ - Metric rows: exactly 4 (§C.3 hard requirement).
183
+ - Immutable scaffold (`corner-*` head spans · `corner` viz spans · `lane-head/body/foot` triad · `.lane-metric`+`.lane-viz` split · `.lane-blocker`+`.lane-link` pair · `class="svg-soft"` · `data-repo` · `target="_blank" rel="noopener"` · `<span class="num">29</span>` · `<span class="stamp-block portfolio">ENCODING</span>` · `<span class="cat">· ZPE-BIO · ECG CODEC</span>`): all present, all unchanged.
184
+
185
+ **Repo / web truth sync this pass:** None required. Wave-1 `gh repo edit` description + topics still in place (verified `gh api repos/Zer0pa/ZPE-Bio --jq '{description, topics}'` this session — bounded ECG description; topic list excludes `eeg`/`wearable`/`medical-devices`/`electrophysiology`/`digital-health`/`lossless-compression`/`machine-learning`/`artificial-intelligence`/`embedded-systems`). HEAD unchanged at `ae2751893dcc`. Wave-2 §B line 476 marked R4 topic-prune as the only repo correction — already done.
186
+
187
+ **Resistance risks checked and not triggered:**
188
+ - **R1 Shape-match design / Benchmark-shape mimicry:** new viz is ECG-specific (contract envelope + corpus-range hatching + breach point) — not DM3-graph or Polymath-NPU shape. Removing the data leaves no recognisable card.
189
+ - **R2 Rush to green-flag:** did not declare done after the v1 5,842-byte SVG; trimmed and re-applied to land near the §C.3 ceiling. Did not flip status / mark "Hits" preemptively.
190
+ - **R3 Approval via packet quality:** receipts describe what was done; the page itself carries the truth. Polished prose did not substitute for the actual fix.
191
+ - **R4 Efficiency-as-ownership-fracture:** verified repo + page continuity together; repo G4 still in place; card body + viz now align with repo README "Honest blocker" wording on PTB-XL out-of-contract.
192
+ - **R5 Flattery-as-freedom:** did not redesign headline (rated "Hits" — kept). Did not invent metrics. Did not widen scope. Did not soften §A non-claim language.
193
+ - **§C.4-related:** lane was rated "Body Approaches / Viz Approaches" in Wave-2 §C.4 row 792. The Wave-2 fixes target exactly those two dimensions; headline (rated "Hits") was left alone.
194
+
195
+ **Receipts not produced (infrastructure state, not edit-related):**
196
+ - Desktop block-in-context screenshot at 1440px and mobile screenshot at 375–414px **not captured**. Reasons:
197
+ - Live dev server at `127.0.0.1:4631` returns HTTP 500 with Astro Cloudflare adapter `runInRunnerObject` / `getComponentByRoute` error (`node_modules/.vite/deps_ssr/astro_app_entrypoint_dev.js:195:20`). Pre-existing upstream routing failure; my edit is HTML-only inside one article block and cannot have caused this.
198
+ - Production build (`bun run build`) halted at `embed-lanes` step on a frontmatter fence error in `src/content/lanes/encoding/_proofs/_review/fpo_L_area_review_2026-05-05.md` — different lane's proofs file, not in my edit scope.
199
+ - Static structural confirmation stands in (29-check matrix executed this pass): SVG XML well-formed (`xml.etree.ElementTree.fromstring` PASS); HTML tag balance clean (`html.parser` 0 errors); all immutable scaffold tokens present; data-status flipped; CTA href correct; metric rows exactly 4.
200
+
201
+ **Status:** Wave-2 fix applied. Headline / metrics / CTA / blocker unchanged (rated "Hits" or already verbatim from §A). Body paragraph and viz updated to surface the PTB-XL contract-split visibly per §C.3. Awaiting operator visual review when dev server / build infrastructure recovers.

205
+ ### 2026-05-07 · Landing-card wave · slot 29 populated + repo G4 part 1 (Corridor Agent)
206
+
207
+ **Brief:** `/Users/Zer0pa/orchestration-state/LANDING_CARD_CENTRALIZED_BRIEF_2026-05-07.md` §A/§B/§C slot 29.
208
+
209
+ **Repo front door (G4) — partial completion:**
210
+ - Description rewritten from "ZPE-Bio V0.0: Deterministic ECG codec — Python + Rust core; 100% integrity across 4 standard corpora (MIT-BIH, NSTDB, EDB, PTB-XL); CI parity-gated" → "Deterministic ECG codec — Python + Rust, CI parity-gated. Bounded clinical-mode contract: PRD ≤ 2.32% on MIT-BIH (48/48, mean PRD 1.12%); PTB-XL boundary disclosed (max PRD 5.29%). Cardiologist-equivalence and regulatory closure out of scope." This removes the "100% integrity across 4 corpora" overclaim flagged in §A and surfaces the PTB-XL boundary inline.
211
+ - Topics replaced with bounded list: `bioinformatics, biosignal-processing, codec, computational-physics, ecg, mit-bih, physionet, ptb-xl, python, rust, signal-processing, time-series`. Dropped per §A/§B G4: `eeg`, `wearable`, `medical-devices`, `electrophysiology`, `digital-health` (ECG-only conflict), `lossless-compression` (codec is fidelity-bounded-LOSSY per README), `machine-learning`, `artificial-intelligence`, `embedded-systems` (overscope vs claim surface). Added: `ptb-xl` (precise corpus topic).
212
+ - **G4 not done by this agent (flagged for repo team):** the "contract-precision" issue §A flags (clinical contract `PRD ≤ 2.32%` vs max recorded `2.324893%`) is below README precision (which rounds to 2.32%). This is a low-level proof-artifact reconciliation — either widen the contract figure or reflect the precision of the recording — and is not a front-door metadata fix. Suggest repo team open a small PR against `validation/results/BENCHMARK_SUMMARY.md` and the underlying aggregate JSON.
213
+ - Verification: `gh api repos/Zer0pa/ZPE-Bio --jq '{description, topics}'` confirms the new state.
214
+
215
+ **Landing card (slot 29) — populated:**
216
+ - Block label: `<!-- CARD: ZPE-Bio · ENCODING · STATUS=POPULATED -->`
217
+ - Article: `<article class="cell lane" data-lane="zpe-bio" data-portfolio="encoding" data-status="populated">`
218
+ - Headline: `ECG with a <span class="accent">fidelity contract.</span>` (5 words; accent on last 2; 30 chars). Crystallizes §B "evidence-backed ECG codec beta" without implying EEG/wearable/regulatory.
219
+ - Lane-tag: `· ZPE-BIO · ECG CODEC` (mirrors DM3's `· DM3 · COMPUTATION SUBSTRATE` form).
220
+ - Human paragraph: 4 sentences, ~340 chars, 1 `<strong>` span on "MIT-BIH 48/48 integrity". Centers the bounded ECG proof surface and explicitly separates human-equivalence/regulatory closure per §B direction.
221
+ - Four metrics (exact §B picks, all README-anchored): MIT-BIH integrity 48/48; Mean PRD 1.12%; Mean CR 1.32×; PTB-XL integrity 100/100. `data-count` animations on the two scalars.
222
+ - Visualization: bespoke monochrome ECG schematic — raw trace at full opacity, deterministic reconstruction at 50% opacity sitting inside a dashed PRD ≤ 2.32% envelope, 4-corpus pass tape (MITDB 48/48 · NSTDB 15/15 · EDB 90/90 · PTB-XL 100/100) with a small triangle marker above PTB-XL flagging the disclosed boundary, plus 6 monospaced annotation lines including the CI parity-gate note. SVG = 2837 bytes (within §C.3 1.8–3.2 KB envelope). Caption `FIG · BOUNDED ECG RECONSTRUCTION UNDER 2.32% PRD` (48 chars / 50 limit).
223
+ - Honest blocker: "Cardiologist-equivalence (κ ≥ 0.85) PENDING. No regulatory clearance, no medical-device claim, no EEG or wearable scope. PTB-XL boundary disclosed at max PRD 5.29% — outside the clinical 2.32% contract." (~245 chars; preserves all four §A non-claim items verbatim.)
224
+ - CTA: `OPEN REPO SURFACE → https://github.com/Zer0pa/ZPE-Bio` (per §B CTA directive).
225
+ - Status flip: marker `STATUS=PLACEHOLDER → POPULATED`; article `data-status="placeholder" → "populated"`. `data-lane`, `data-portfolio`, `<span class="num">29</span>`, `<span class="stamp-block portfolio">ENCODING</span>` untouched.
226
+
227
+ **Truth-basis line:** §A `Controlling proofs: reports/ZPE-Bio.md:29-46,56,89; falsification/ZPE-Bio.md:19-50` + §B `Slot 29` headline/paragraph/metric/CTA directive + ZPE-Bio README `## Key Metrics` and `### Honest Blocker` at HEAD `ae2751893dcc`.
228
+
229
+ **Diff-scope assertion:** populated via `python3 /tmp/zpe-bio-card-populate.py` — atomic `os.replace()` after a single regex match against the placeholder block (script enforces `count == 1`). The 150,284-byte template was modified only inside `<article data-lane="zpe-bio">…</article>` and its preceding `<!-- CARD: -->` comment. No `data-lane` boundary was crossed; no shared CSS, JS, page wrapper, layout primitive, or neighbouring article was touched.
230
+
231
+ **Receipts not produced (infrastructure gap):**
232
+ - `bun run build` blocked by `scripts/preflight-disk.mjs` — only 0.15 GiB free on the worktree volume; preflight requires 2.0 GiB. Not a content issue. Operator-side: free disk and re-run.
233
+ - Block-only / block-in-context / mobile screenshots not captured — corridor agent runs without a browser. Available structural confirmations stand in:
234
+ - HTML well-formedness via `html.parser` (no errors).
235
+ - Immutable-scaffold token check: 4 `corner-*` head spans + 4 `corner` viz spans + `lane-head/lane-body/lane-foot` + `lane-metric/lane-viz` split + `lane-blocker/lane-link` pair + `class="svg-soft"` on `<svg>` + `data-repo="zpe-bio"` + `target="_blank" rel="noopener"` + portfolio chip + `<span class="num">29</span>` — all present.
236
+ - Slot-population progress count: 15 `data-status="populated"` and 15 `data-status="placeholder"` (two-row grid will hold rhythm).
237
+
238
+ **Status:** Slot 29 populated. Repo G4 description+topics done; G4 contract-precision deferred to repo team. Awaiting operator visual review on the page once dev server is up.

244
+ **Output:** `/tmp/lane-ZPE-Bio/STATE.md`
245
+
246
+ **Severity summary:** No CRITICAL drifts. Two website-side drifts found: `commit_sha` frontmatter is empty (`""`) — renders "UNSET" publicly in Zone-05 Readiness stamp (MEDIUM); `headline_metric` frontmatter carries appended invented copy not derivable from README (LOW). One boundary-list wording ambiguity flagged for operator decision (LOW). One repo-side flag: README's own `Commit SHA` in `## Repo Identity` shows `b57bd19f1609`, stale vs actual HEAD `ae2751893dcc` (RF-01, MEDIUM — repo team, not website). `audit-readme-fidelity` PASS (18 lanes, 7 invariants). Live page 200 OK. No HF public presence confirmed.

70
+ ## Lane truth envelope (§A summary)
71
+
72
+ ZPE-Bio is a **deterministic ECG codec** on a **PRD ≤ 2.32% clinical
73
+ contract**, evidenced on four PhysioNet corpora with Python/Rust CI parity.
74
+
75
+ **Evidenced-now surface** (`reports/ZPE-Bio.md:29-46,56,89`,
76
+ `falsification/ZPE-Bio.md:19-50`):
77
+
78
+ - MIT-BIH 48/48 integrity · mean PRD 1.12% · mean CR 1.32× · within contract
79
+ - NSTDB 15/15 integrity · max PRD 1.96%
80
+ - EDB 90/90 integrity
81
+ - PTB-XL 100/100 integrity · max PRD 5.29% · **outside the 2.32% contract** · disclosed
82
+ - Python and Rust cores CI parity-gated
83
+
84
+ **Non-claim boundary (NON-NEGOTIABLE):**
85
+
86
+ - Cardiologist-equivalence (κ ≥ 0.85) **PENDING**
87
+ - No regulatory clearance
88
+ - No medical-device claim
89
+ - No EEG, wearable, or electrophysiology scope beyond ECG

+
91
+ ## How to recover the lane from this snapshot
92
+
93
+ After a Mac wipe, the full lane can be resumed from:
94
+
95
+ 1. **Code, proofs, validation, release packaging** → `git clone https://github.com/Zer0pa/ZPE-Bio`
96
+ 2. **Product-page build + receipts** → `hf download Zer0pa/ZPE-Bio-lane-state --repo-type dataset`
97
+ 3. **Lane-queue log** → see `INDEX.snapshot.md` in this dataset (authoritative copy is at orchestrator surface)
98

+ To re-render the product page:
100
+
101
+ ```bash
102
+ cd <wherever you placed>/product-page-build
103
+ python3 -m http.server 8765
104
+ # open http://127.0.0.1:8765/ — reference standard for the XR template family
105
+ ```
106
+
107
+ The build is a single self-contained `index.html` plus images. It fetches
108
+ fonts from Google Fonts and the Pretext layout module from `unpkg.com`. No
109
+ local Node/Astro/Bun runtime required for static review.

111
+ ## What is safe to delete locally
112
+
113
+ After this dataset is pushed and verified:
114
+
115
+ - `/Users/Zer0pa/Desktop/zpe-bio-product-page-build/` — safe (mirrored here)
116
+ - `/tmp/zpe-bio-*` build scripts — already cleaned by shell session resets
117
+ - `/tmp/zpebio-*.png` landing-card receipts — already cleaned
118
+
119
+ ## What is still not remotely safe
120
+
121
+ - `/Users/Zer0pa/orchestration-state/lane-asks/ZPE-Bio/INDEX.md` — orchestrator-managed,
122
+ not lane-owned. A snapshot copy is in this dataset but the authoritative source
123
+ lives at the orchestrator surface and must be backed up by the orchestrator's own
124
+ durability sweep.
125
+ - Landing-card edits to slot 29 (`<article data-lane="zpe-bio">…</article>`) in
126
+ `landing-rd-v3.template.html` — the worktree at
127
+ `/Users/Zer0pa/Website-fresh/.claude/worktrees/landing-rd-v3/site-v2/` is no longer
128
+ present on this Mac. If those edits weren't committed to GitHub on the
129
+ `design/landing-rd-v3` branch by the Website Orchestrator, only the rendered
130
+ screenshots in `/Users/prinivenpillay/Desktop/landing-rd-v3-r*/` retain the visual
131
+ record. This is **out of ZPE-Bio lane-agent scope** but flagged here for orchestrator
132
+ attention.
133
+
134
+ ## Operating-state note (2026-05-10)
135
+
136
+ This snapshot is taken under URGENT durability discipline — the Mac is
137
+ expected to be formatted shortly. Feature work on the lane has paused
138
+ until durability is confirmed across GitHub + Hugging Face for all 31
139
+ lanes in the encoding/computation/ai/design/insilico/gnosis portfolios.

The previous flex-items-center +
1025
+ min-height pattern let the icon's intrinsic 1380px block-
1026
+ size force the stage to grow past its declared min-height,
1027
+ which is why the footer was 2-3x taller than expected with
1028
+ the visible glyph orphaned in the upper portion. New
1029
+ approach: stage has a FIXED `height`; icon is absolutely
1030
+ positioned + transform-centered inside it, so the icon's
1031
+ intrinsic size cannot influence the stage height at all.
1032
+ No flex, no padding, no surprises. The icon is decorative
1033
+ (brand mark also in the header + meta row) so it stays
1034
+ hidden from AT. --> <div class="footer-stage"> <img src="http://127.0.0.1:4631/zer0pa-icon.png" alt="" class="footer-icon" width="495" height="527" loading="lazy" decoding="async" aria-hidden="true"> </div> <!-- FOOTER LINKS — HORIZONTAL ROW --> <div class="px-6 pb-6"> <div class="footer-links-grid"> <a href="https://reddit.com/r/zer0pa" target="_blank" rel="noopener noreferrer" class="footer-link-block">REDDIT</a> <a href="https://huggingface.co/Zer0pa" target="_blank" rel="noopener noreferrer" class="footer-link-block">HUGGING FACE</a> <a href="https://github.com/Zer0pa" target="_blank" rel="noopener noreferrer" class="footer-link-block">GITHUB</a> <a href="http://127.0.0.1:4631/contact/" class="footer-link-block">CONTACT</a> </div> </div> </footer>
