feat(registry): add SN62 Ridges TaoMarketCap candle-chart data-artifact (#4069)

[ultrahighsuper]

Summary

Registers SN62 Ridges's public OHLCV candle-chart dataset as a data-artifact surface — a no-auth JSON time-series of Ridges's alpha-token price/volume, a dataset the registry did not yet capture.

Surface

• kind: data-artifact
• url: https://api.taomarketcap.com/public/v1/subnets/62/candle-chart/
• provider: taomarketcap (existing)
• auth_required: false, public_safe: true, authority: community, review.state: community-submitted

Proof of ownership / authority

• source_urls: the TaoMarketCap developer API docs and tensorplex-labs/subnet-docs/data/62/subnet.json (confirms SN62 Ridges's identity). api.taomarketcap.com is a provider-claimed on-chain indexer; the endpoint is listed in its public OpenAPI with an optional API key (no-auth access supported).

Verified live + public + safe

• GET https://api.taomarketcap.com/public/v1/subnets/62/candle-chart/ → HTTP 200, application/json, ~224 KB, no auth.
• Real payload: an array of hourly OHLCV candles, each scoped to subnet_id: 62, with period_name, timestamp, block_number, open/high/low/close, volume, start_volume, tao_price_usd/eur.
• Public-safe: scanned the full body for SS58/base58 wallet or hotkey strings → zero matches; price/volume time-series only.

Non-duplication

Distinct from Ridges's existing surfaces — source-repo, the first-party subnet-api (/retrieval/top-agents) and openapi on agent-upload.ridges.ai. This is a different host and a different dataset: an on-chain price/volume time-series, which the first-party agent API does not provide. No open PR targets SN62.

Scope note (relative to #4069)

#4069 asks for SN62 Ridges's public data artifact. This standalone, machine-readable OHLCV price/volume dataset is exactly that, on a reliably-reachable indexer host.

Validation (local)

• npm run validate:surface -- registry/subnets/ridges.json → passes (4 surfaces)
• npm run scan:public-safety → passes
• npm run validate:schemas → passes
• npx prettier --check registry/subnets/ridges.json → clean
• git diff --stat → single file, 19-line pure append (no top-level metadata or other surfaces touched)

Template Used

• Subnet surface

Closes #4069

Review summary
This PR appends a single new `data-artifact` surface (SN62 Ridges TaoMarketCap OHLCV candle-chart) to the existing `registry/subnets/ridges.json` manifest, matching the netuid (62) and following the exact same shape as the already-merged SN73 MetaHash candle-chart surface in the reference context. It is single-file, append-only (no edits to top-level metadata, curation, or other surfaces), uses `authority: community` / `review.state: community-submitted`, and does not duplicate the subnet's existing first-party `subnet-api`/`openapi` surfaces on a different host (agent-upload.ridges.ai vs api.taomarketcap.com) or the native-chain-promoted `source_repo`/`website_url` fields.

Nits — 5 non-blocking

• The `curation.gap_notes` array (unchanged in this diff) still lists "No verified standalone static data artifact yet." — worth a follow-up to update since this PR now fills that gap.
• Trailing-slash URL `.../candle-chart/` is consistent with the sibling MetaHash entry but confirm TaoMarketCap's API is stable on trailing-slash vs non-trailing-slash paths.
• Consider a small follow-up PR to prune the now-stale gap_notes entry in ridges.json's curation block.
• registry/subnets/ridges.json:122 uses the generic TaoMarketCap documentation landing page as source evidence; a direct OpenAPI/spec URL or endpoint-specific documentation link would make the source proof stronger and less dependent on JS-rendered docs.
• registry/subnets/ridges.json:123 links the mutable `main` branch for the Tensorplex subnet identity source; pinning this to a commit would make the evidence reproducible.

Linked issue satisfaction

Addressed
The PR adds exactly one data-artifact surface to registry/subnets/ridges.json pointing to a real, live, no-auth TaoMarketCap OHLCV endpoint scoped to subnet_id 62, with source_urls documenting the provider docs and the tensorplex subnet-docs identity confirmation, satisfying the issue's ask for a public data artifact for SN62.

Signal definitions

• Related work = same linked issue, overlapping active PRs, or title/path similarity.
• Change scope = cached public metadata such as size labels, draft state, and review-burden hints.
• Validation posture = whether the PR provides enough public validation/test evidence for maintainer review.
• Contributor workload = public contributor activity and cleanup pressure, not a repo-wide quality failure.
• Contributor context = public GitHub/Gittensor identity context; non-Gittensor status is not a blocker.
