Land Pine sweep evidence with a current component evidence matrix - #956

Scope

Integrate the Claude-authored Pine landscape sweep from trading-cc-reviewer, countersigned by trading-cc, as retained research evidence for us-equities/backtesting-engine. Its published October9 manifest and completed sweep now appear in the regenerated component-evidence matrix and Markdown report. The supplied eleven research payloads retain their exact bytes; the forward correction updates generated display evidence, existing registry bindings and a permanent publication-freshness check.

• Base commit: a56f85e8397751d36fdbdc03910f15ac877ad00c.
• Original integration: 2e76f125bfeb484df7d9b2a97a3e86893e843482.
• ONE forward matrix correction: 308691207da0f3e87b91580e1a9af00f253e9189, sole parent the original integration.
• Tested head tree: 0d4edff91f0a97154190defcac388888638aa1bc.
• Tested actual merge with latest captured main fcdeae42c82b2279ccd5a0ee3867fd70ba1beff2: tree 0fadba11c8c080af219c0eb84277c221a65aee72. The earlier captured ff69fc86 composition also passed before main advanced.
• Lane: lane:shared; the shared convergence/evidence surfaces require other-lane acknowledgement before CC landing.
• Correction paths: catalogs/landscape/component-evidence-matrix.json, docs/component-evidence-matrix.md, tests/test_component_matrix.py, and three existing file rows in manifests/evidence.json. Generator, ledger, dated sweep manifest, source reviews/returns and usage payloads retain their bytes. The whole PR retains its original evidence integration plus these three additional generated/test paths.

The native generator now displays manifest-20261009.json, four qualifying completed sweeps and the resulting pin/convergence factors. The new check fails if recorded completed sweeps are omitted or displayed newest-manifest freshness precedes a published input; it permits future newer manifests. There is no runtime adoption, winner-selection, strategy or broker-authority change.

• Preserved primary Pine source reviews: LuxAlgo/PineTS v0.11.0, c5e6b0efee7e42d78b42d96f14173f38be082551, PyneSys/pynecore cab1266911a31245e885dc06789f900717be9e98, and s7cret/backtest_engine v5.0.0rc5, 0a8a6a62e3556e9c3ef4cd0b5bcd048ce3cd62a0. Source review remains distinct from native runtime adoption or comparative superiority.
• Maintained native generator at main ff69fc865ce72a6717a36a8f06fdac79038bd515, scripts/component_matrix.py: newest_sweep_manifest:519, convergence context :715, sweep accounting :730, native writer/automatic registration :1231-1253, freshness rejection :1261. Exact generator SHA256 ab4cbdd0521d2a42108395509589b12a82e83afef76e6377574177ff54c5d899 matches the integration source; it was invoked through its supported --write, with no rebuild/fork.
• Same main scripts/host_receipts.py, register_file:710, provides actual-byte evidence registration. docs/lanes.md:95-122 requires native --write for generated shared reports. The existing real-repository freshness test and added independent recorded-input check enforce publication freshness.

The actual main+corrected-head composition was materialized in a detached verification checkout, with native Git merging without conflicts or manual registry/report repair. Its tree matches the independent merge-tree result. These checks do not replace the CC's designated integration read, current-head CI, readiness or landing gates.

Decision record

~/.local/state/native-agent-stack/research/harness-rules-20261010/PINE-PR956-MATRIX-CORRECTION-20261010.md records first-hand stale/fixed checks, unchanged research hashes, native generator bindings, the added publication check, actual merged-tree proof, final gates and exact forward lease.

Host evidence

No host receipt, runtime default, guard or broker operation is changed. Existing host/evidence acceptance and source-review boundaries remain the author's recorded ones.

Checklist

• Original research payload preserved; native generation and registration only, plus the requested permanent check.
• Required stale/fixed/head/merged-tree checks and FULL validation pass.
• No credentials or host user name/expanded home path in new source, records or PR text.
• No workflow permission, billing, runtime adoption, winner selection or host guard change.
• Peer-owned and protected lanes preserved; S6: retain secret denials across diagnostic exemptions #960 remains owner-held.
• Renewed exact-head reads, other-lane acknowledgement and complete current-head CI remain CC-owned landing gates.
