docs: make BandScope public surface rehearsal-first and license-aware

[seonghobae]

Summary

Turn BandScope's public repository surface into a rehearsal-first, product-facing entry point without changing runtime behavior or competing with current feature, MIR, supply-chain, Figma, or workspace writers.

• keep one exact Ask DeepWiki badge and the public docs/index.md landing source;
• organize value around song → section → role, visible confidence, editable analysis, local-first operation, and rehearsal outputs;
• distinguish shipped capabilities from coming-soon playback goals;
• retain truthful setup, verification, architecture, security, dependency, SBOM, governance, GitHub-bootstrap, and cross-platform documentation;
• preserve the MIT grant for ContextualWisdomLab-owned source while distinguishing third-party/native/model licenses;
• fail closed on the tracked SoundFile/libsndfile commercial-policy defect owned by licensing: replace bundled libsndfile LGPL runtime path #1129.

Direct repairs

The prior Ready head was two commits behind protected develop. Commit d6d10a7 integrates develop@314ddeae7b775a4957594b599358c8255617eb2e through a two-parent, non-force history while preserving every branch delta.

The private-reporting finding was repaired with RED 717966b and GREEN 980106c. The explicit public contact request may contain only a GitHub handle and a request for private contact; vulnerability details, affected versions, reproduction steps, logs, links, and attachments remain prohibited until a maintainer confirms a private channel.

Current-head review then found that the public landing pages described disabled playback controls as shipped:

• RED b5336d2 requires truthful coming-soon language and one canonical security-advisory destination.
• GREEN c6442ee separates current local intake/analysis/range/overlap/override/export behavior from coming-soon stem preview, Loop section, and Solo / mute others controls.
• The review suggestion to move reporting back to seonghobae/bandscope was rejected after checking the current repository owner. The stale personal-fork URL was instead removed from .github/ISSUE_TEMPLATE/config.yml, and the verifier now rejects its return.
• f094306 adopts canonical formatter prerequisite repair(ci): format consolidated supply-chain policy test #1176 as an ordinary second parent. It does not copy or rewrite that one-file delta.

No runtime, public API, schema, dependency, packaging, or deployment behavior changed.

Verification

Fresh verification on the exact source tree 51865be6cddac751dfe39a7474e977a6bcadf54e:

• documentation, GitHub-bootstrap, Security Notes, security-pattern, supply-chain, and diff checks: pass;
• Ruff check and Ruff format check: pass;
• focused supply-chain policy suite: 155 passed;
• full analysis-engine suite: 680 passed, 24 native-parity skipped, 100% statement/branch coverage;
• the two emitted warnings are existing bounded Librosa short/empty-signal warnings, not deprecations or failures.

The remote exact-head tree is the same verified tree. Hosted exact-head checks are reacquired after every head movement; predecessor results do not transfer.

Coordination and merge gate

This remains the existing public-surface writer. #1129 owns removal/replacement of the libsndfile-backed runtime path. #1176 remains the canonical owner of the formatter repair now integrated by ancestry. The repository-wide product/technical gap baseline remains with its existing canonical gap lane rather than being copied into this PR.

Current authority:

• protected base: develop@314ddeae7b775a4957594b599358c8255617eb2e;
• exact head: f094306167a38176237da3c82f5a8d605549760b;
• protected-base relation: 20 commits ahead / 0 behind;
• changed files: 7;
• mergeable: true.

Keep Draft until the unchanged exact head has every applicable repository and central CI/build/security/SAST/SBOM/coverage gate terminal-success, zero valid unresolved findings, and a qualifying independent non-author last-push approval. Do not self-approve, bypass protection, synthesize status, force-push, or destructively rebase.

Security Notes

• Attack surface: public security-reporting destinations and documentation claims.
• Trust boundary: security reports must remain private; the public fallback is deliberately metadata-only.
• Safe failure: stale personal-fork routing and unimplemented playback claims are rejected by repository verification.
• No credentials, sensitive report contents, runtime permissions, network execution, or dependency changes are introduced.

Publication boundary

docs/index.md is only publication source. GitHub Pages is complete only after protected integration, organization-owned enablement, and successful live HTTPS/content verification.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 98010

Resolve the security-reporting destination before merge so confidential reports reach the intended repository, and mark stem preview as planned rather than currently available.

Devin Review found 1 new potential issue.

Zero-trust release lane note (touhidzaman007)

Unresolved Devin thread on SECURITY.md remains valid: private fallback still says "established private channel" with no address/form/channel.

Authoritative sources checked:

• PR head SECURITY.md
• origin/develop SECURITY.md (contains seonghobae@example.com placeholder — not usable)
• Org ContextualWisdomLab/.github/SECURITY.md ("email the lab maintainers directly" — no address)

Status: SECURITY_CONTACT_BLOCKED — will not invent a contact. Need owner-provided canonical private reporting destination, then re-run exact-head proof / merge gate.

In `@README.md`:
- Line 87: Separate implemented capabilities from planned functionality in the
README: keep local audio intake, offline analysis, section/role outputs,
range/overlap warnings, manual overrides, and CSV/JSON exports in the current
implementation description, while marking stem preview as a goal or coming-soon
feature in the README overview and docs index. Ensure the current-features
section does not claim support for Workspace.tsx actions such as Play stem, Loop
section, or Solo / mute others.

In `@SECURITY.md`:
- Around line 12-14: Update SECURITY.md and scripts/checks/verify_docs.py at
lines 12-14 and 49-50 to use the seonghobae/bandscope repository for both
advisory and security-contact URLs, and update the verifier’s expected-value
checks to detect mismatches against those canonical URLs.
