Summary

Fixes false parser incompleteness when ordinary Markdown possessives cross inline-code, table-cell, list or heading boundaries. Transports the reviewed source into the pinned runtime patch and adds 69 installed adapter controls.

- canonical prose can consume later text as an unterminated shell quote
+ prove exact original Markdown text ownership before masking punctuation
+ retain raw shell continuations and shell-word precedence

Related: ClawHub #4046. WAV consumer compatibility remains required before recovering that original upload.

Scope

• Scanner adapter
• Release/CI/repo automation

Security / Trust Impact

• Security/trust impact explained

Findings still inspect original bytes. Unknown mappings, executable expansions, raw HTML and continued shell operands retain their conservative treatment. Existing models, reasoning, service tiers, budgets, source/dependency pins and lock bytes remain unchanged. No finding suppression or publication override is added.

Evidence

• Before: unchanged PixelLab 3.0.0 is 123/126 fully inspected text files; three possessive-containing Markdown files remain partial.
  After: 126/126 text files; only 11 generated incomplete-reference rows disappear. All 58 other raw finding payloads and 147 reference payloads remain unchanged. The original WAV exclusion remains explicit.
• All 30 retained input inventories and suppression payloads/counts match. Other 29 uploads preserve complete findings and analysis/reference payloads.
• Exact reported continuation control ($CMD followed by a continued Markdown list) stays partial and retains destructive operands after the repair.
• Ordinary upstream patch application reconstructs all 135 installed source/resource files plus pyproject/uv.lock byte-for-byte against reviewed producer bda4f884f6c59fd206b5e4477fa5c278ac6ce43f.
• 1,170 installed adapter controls pass. Source validation: 1,649 passed; 3 native-shfmt comment expectations fail identically on the previous 826 source and are retained. Independent source cumulative-plus-repair and current integration reviews qualify P0–P3; the repair review completed all 5 passes.

Verification

• go test -count=1 ./...
• go vet ./...
• go run ./cmd/clawscan --help
• Installed adapter controls, source reconstruction and 30-original paired proof above
• Docs site: N/A

Merge Danger

Door: two-way; revert this transport commit to restore the prior source.

Blast Radius: scanner. Native runtime publication and production consumer activation require their normal separate gates.

Codex review: needs maintainer review before merge.

What this changes

The PR extends canonical Markdown ownership to recognize prose apostrophes without masking continued shell operands.

Example: A Markdown guide contains Observe last_response's completed result. followed by substantial ordinary prose.

• Before: The possessive can open a shell quote and leave static inspection incomplete.
• After: The parser recognizes the apostrophe as prose punctuation while retaining original bytes for findings.

Review scores

Measure	Result	What it means
Overall readiness	🦐 gold shrimp (3/6)	A focused, useful repair with meaningful controls and no identified defect; supplied runtime results are summarized rather than directly inspectable.
Proof confidence	🦐 gold shrimp (3/6)	This collaborator-authored PR is outside the ordinary contributor proof gate; its body reports PixelLab improving from 123/126 to 126/126 inspected text files with other finding payloads retained, while inspectable coverage comes from the installed-package harness.
Patch quality	🐚 platinum hermit (4/6)	No actionable review findings were identified.

Product

Kind: Bug fix · Worth it: Yes · Fix scope: Complete
User problem: Benign possessives crossing Markdown syntax boundaries can prevent complete static inspection.
Reason: The collaborator-authored repair addresses the stated parser defect within the existing ownership mechanism and does not claim complete publication recovery.

Merge readiness

✅ Ready for maintainer review

Keep this PR open: it addresses a current scanner completeness defect, preserves conservative shell handling, and has collaborator-approved direction; no introduced defect was identified.

Tests

• Missing end-to-end proof: The PR reports installed before/after scans, but supplies no inspectable CLI trace showing the changed path; ordinary contributor proof is exempt for this collaborator-authored PR.

Agent review details

How this fits together

ClawScan installs a patched SkillSpector inside its scanner runtime; Markdown source enters bounded ownership and shell inspection, which produce raw findings and inspection completeness records.

Technical review

Best possible solution:

Land the bounded ownership refinement while keeping runtime activation and PixelLab's WAV compatibility repair separate.

Do we have a high-confidence way to reproduce the issue?

Current-main source excludes several composed prose cases from punctuation ownership, and the added fixtures exercise those paths; this review did not execute target code.

Is this the best way to solve the issue?

Extending the existing canonical ownership parser is appropriate because it retains exact source mappings, shell-word precedence, conservative fallback, and raw finding production.

AGENTS.md: found and applied where relevant.

Codex review notes: model internal, reasoning medium; reviewed against aff544dc623c.

Provenance checked

• Canonical Markdown ownership keeps the original intent (0929eca: Use original-document canonical parsing to distinguish Markdown delimiters while retaining uncertain mappings and raw findings.)
• Container shell projection keeps the original intent (1aedf7b: Refine container delimiter handling without consuming command contents or granting ownership to reconstructed executable text.)
• Raw-line continuation guard keeps the original intent (unknown: The pinned upstream source explicitly prevents runtime-selected commands from consuming later text through prose masking; this PR reuses the condition for canonical ownership.)

Testing

Proof path: in-process harness.

Security

None.

Evidence

What I checked:

• Introduced change and current-main boundary: The pinned diff extends the existing ownership parser and adds installed adapter controls; GitHub still reports main at aff544d and the reviewed head at a1aed5d. (docker/clawscan-runtime/patches/skillspector-responses.patch:2391, a1aed5d25b8b)
• Conservative regression controls: The added suite covers LF/CRLF offsets, continued runtime-selected shell commands, existing shell words, threat locations, uncertain contexts, and reconstructed fragments; Docker runs this suite against the installed package. (docker/clawscan-runtime/tests/test_skillspector_markdown_prose_composition.py:60, a1aed5d25b8b)
• Original design and feature ownership: Merged fix: distinguish Markdown code closers from obfuscation markers #99 and fix: preserve Markdown container delimiter ownership #105 established bounded original-document ownership while preserving command contents, findings, uncertain mappings, and reconstructed-payload restrictions; the PR extends that design. (docker/clawscan-runtime/patches/skillspector-responses.patch:1413, aff544dc623c)
• Policy and inspection limits: The complete root AGENTS.md was read; no nested policy, matching maintainer notes, or pr-simplify skill was found. The user's single-reviewer and read-only instructions supersede the bundled autoreview helper. A follow-history query encountered a missing promisor object; scoped commit history and relevant blame remained available. (AGENTS.md, a1aed5d25b8b)
• Dependency contract inspected: The Dockerfile explicitly installs and patches this pinned dependency. Its original Markdown shell projection retains a shell-word precedence pass before masking punctuation, and the PR leaves that pass intact; no AGENTS.md was listed in the pinned dependency tree. (src/skillspector/nodes/analyzers/static_patterns_tool_misuse.py:5074, 95a52d89fa16)
• Linked user report and separate remaining blocker: Skill @Shilo/pixellab-pip 3.0.0 stuck in pending publication: ClawScan result missing, version slot taken clawhub#4046 documents PixelLab 3.0.0 pending publication; Shilo's follow-up identifies a separate WAV exclusion/reference-caveat compatibility problem, which this PR expressly leaves unresolved.
