docs(miner): AMS auth/identity research — hosted login-layer options

[lourincedaging0-commits]

Closes #5217.

What

A research-spike comparison document (packages/loopover-miner/docs/ams-auth-identity-research.md) surveying auth/identity approaches for a hosted, multi-tenant AMS — evaluated against the GitHub App / installation-token patterns gittensory already operates, per the issue.

Grounding (existing precedent, cited not changed)

• src/orb/broker.ts (Orb: fleet calibration collector + analytics (retire per-instance App; feed from review_audit) #1255) — the das-github-mirror token-broker: enrollment-secret → short-lived GitHub installation tokens, installation_id bound server-side at issue time (never from the request).
• src/orb/oauth.ts — maintainer-OAuth self-enrollment proving installation-account admin server-side.
• src/orb/broker-client.ts, src/github/app.ts (token cache), src/auth/security (opaque-token/hash primitives).
• packages/loopover-miner — the current GITHUB_TOKEN-env, no-login baseline.

Comparison (2-3 approaches, with the required broker-interaction notes)

Option	Broker interaction
1. GitHub OAuth + existing self-enrollment (recommended)	reuse unchanged — GitHub is already AMS's authority
2. Managed IdP (Auth0/Clerk/WorkOS) alongside	reuse (fed by an identity↔installation linking step); earns its keep only for non-GitHub/SSO tenants
3. Custom JWT/OIDC	reuse (run alongside); most to build + secure — not recommended

In every option the broker's server-side installation_id binding is reused, not replaced (the token path is orthogonal to tenant login).

Scope

Docs-only, per the issue boundaries — no auth flow/token-exchange/provider integration implemented or decided; no change to broker.ts; recommendation is a non-binding input to the maintainer-owned auth design issue.

Review summary
This is a docs-only research-spike PR, but the diff actually adds two separate documents — `ams-auth-identity-research.md` (auth/identity options, tied to #5217 as the description states) and `ams-storage-abstraction-research.md` (storage-backend options, explicitly scoped to a different issue, #5216, per its own header). The description and title only describe and link the auth/identity research and #5217; the storage-abstraction doc is undisclosed scope-creep bundled into the same PR. Both documents are well-grounded, cite existing ORB precedent (`broker.ts`, `oauth.ts`, `d1-adapter.ts`, `pg-adapter.ts`) accurately per the provided reference code, and are explicit that they're non-binding research with no code/schema/auth changes.

Blockers

• The diff bundles a second research document (`ams-storage-abstraction-research.md`, scoped to Research spike: storage-abstraction candidates to replace AMS's node:sqlite local-store #5216) that is not mentioned anywhere in the PR title or description, which only claims to close Research spike: auth/identity provider comparison for hosted AMS #5217 — per repo convention every PR must close/link an eligible issue for everything it contains, and this one is silent on the Research spike: storage-abstraction candidates to replace AMS's node:sqlite local-store #5216 half.

Nits — 5 non-blocking

• Both docs cite specific line numbers (e.g. `broker.ts:8`, `:30`, `pg-adapter.ts:56`) for precedent code — worth double-checking these stay accurate as those files evolve, since a stale line-anchor in a research doc that later informs an implementation issue could mislead.
• The auth doc's Option 2 (managed IdP) and storage doc's Option A (Postgres) both note nontrivial new operational/linking-table cost — consider a short 'open questions for the design issue' bullet list at the end of each doc to make the maintainer hand-off actionable rather than purely descriptive.
• Either split the storage-abstraction doc into its own PR that explicitly links Research spike: storage-abstraction candidates to replace AMS's node:sqlite local-store #5216, or update this PR's description to state both issues it's addressing and why they're combined.
• If combining research spikes for related issues is intentional going forward, consider a convention (e.g. `docs(miner): AMS research spikes — auth/identity (Research spike: auth/identity provider comparison for hosted AMS #5217) + storage (Research spike: storage-abstraction candidates to replace AMS's node:sqlite local-store #5216)`) so the title/description always matches the full diff.
• Diff looks like trivial or whitespace-only churn — Reduce whitespace-only or formatting-only churn and keep the diff focused on substantive changes.

Why this is blocked

• The diff bundles a second research document (`ams-storage-abstraction-research.md`, scoped to Research spike: storage-abstraction candidates to replace AMS's node:sqlite local-store #5216) that is not mentioned anywhere in the PR title or description, which only claims to close Research spike: auth/identity provider comparison for hosted AMS #5217 — per repo convention every PR must close/link an eligible issue for everything it contains, and this one is silent on the Research spike: storage-abstraction candidates to replace AMS's node:sqlite local-store #5216 half.

Improvement	⚠️ ℹ️ Insufficient signal	risk: low · value: insufficient-signal — Nothing measurable for the structural-improvement analyzers on this PR (e.g. no code files changed). LLM value judgment: moderate — Both documents are substantive, well-grounded research spikes that correctly trace existing ORB precedent and give the maintainer-owned design issues a concrete, non-binding starting point, though the undisclosed bundling of two issues' worth of research under one PR undercuts the otherwise clean scope.

• 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.
