docs(observability): record bounded telemetry evidence audit

[kaveh8866]

1. Contribution Path & Summary

• Fast contribution path — bounded documentation/evidence-audit annex

• Core change path — not applicable; zero runtime or contract changes

• Type: docs

• Domain: Docs (with evidence/security findings referred for separate Core review)

• Branch: docs/observability-evidence-audit

• Issue / Spec: Closes no implementation issue yet. Progresses audit(observability): verify current-main telemetry and evidence boundaries #188; links fix(evidence): include nested evidence fields in normalization digest preimage #192, design(evidence): canonical agent-run telemetry correlation contract #189, test(evidence): prove operational and behavioral outcomes remain distinct #191, feat(observability): gate an opt-in OpenTelemetry export adapter #190, roadmap: establish the current canonical SemantIQ product roadmap #177, future: maintain a gated post-alpha capability horizon #178 and project: coordinate Roadmap, Future, and Product Release workstreams #180.

• Why fast: A new evidence annex records source-based findings and next-step gates; no implementation, schema or approved scientific claim is altered.

2. Tests & Verification

• pnpm test — not run: connector-only static documentation change
• pnpm test:python — not run
• pnpm typecheck — not run
• pnpm lint / boundaries — not run
• Exact-head GitHub CI — pending; do not infer pass from an earlier main commit
• Read-only source/issue preflight on main 979cf511e2fc57811fb3cef3766be1653a2e45f5
• Isolated JavaScript demonstration of nested JSON replacer behavior; not a SemantIQ test run

3. Compatibility & Cross-Language Parity

Not applicable: documentation addition only; existing schema 1.0.0, TS/Python SDKs, trace hashing, benchmark scores and fixtures remain untouched.

4. Security & Privacy Impact

• No secrets/credentials or personal data in new document.
• Existing potential payload-redaction and digest-preimage risks are described as scoped findings, not repaired in this PR.
• Follow-up engineering in fix(evidence): include nested evidence fields in normalization digest preimage #192 requires proper security/Core review.
• No data transmission, runtime installation, network egress, or provenance changes.

5. Scientific Methodology & Behavioral Evidence Impact

• Preserves Observed ≠ Inferred, absence ≠ counterevidence, and explicit unknown/insufficient evidence.
• Does not promote scientific evidence, benchmark maturity, or external-implementation claims.
• Classifications are a bounded static audit, not a live integration conformance report.
• Full audit completion remains open in audit(observability): verify current-main telemetry and evidence boundaries #188.

6. Documentation & Guides

• Added Docs/ecosystem/OBSERVABILITY_EVIDENCE_AUDIT_2026-10-10.md
• Keeps existing Integration Graph explicitly historical; no retroactive modifications.
• Defines roadmap handoff and separate gated follow-up issues.

7. Migration Impact & Breaking Changes

• Breaking Change: No
• Migration: Not applicable

8. Review Readiness

• One new documentation file; focused branch from protected main
• Required CI and CODEOWNER approval not yet obtained
• No auto-merge, no branch-protection bypass, no changes to protected main
• No external repository code copied

Requested review: Validate the evidence table, F1/F2/F3 boundaries, the claim/missingness vocabulary, and whether #192 should be prioritized before downstream optional exporter work. This PR must remain Draft until evidence quality is accepted.
