* feat: ETHOS.md — gstack builder philosophy
Standalone document capturing the four principles: The Golden Age,
Boil the Lake, Search Before Building, and Build for Yourself.
Introduces the three-layer knowledge framework (tried-and-true,
new-and-popular, first-principles) and the Eureka Moment concept —
when first-principles reasoning reveals conventional wisdom is wrong.

* feat: Search Before Building preamble section + CLAUDE.md
Add generateSearchBeforeBuildingSection(ctx) to gen-skill-docs.ts.
Every workflow skill now gets a compact router section covering:
- Three layers of knowledge (tried-and-true, new-and-popular, first-principles)
- Eureka moment format and jq-based JSONL logging
- WebSearch fallback clause
- ETHOS.md reference via ctx.paths.skillRoot resolver
Also adds compact "Search before building" section to CLAUDE.md.

* feat: skill-specific Search Before Building integrations
8 template changes:
- /office-hours: Phase 2.75 Landscape Awareness (WebSearch + three-layer synthesis)
- /plan-eng-review: Step 0 search check with layer provenance annotations
- /investigate: external pattern search + search escalation on hypothesis failure
- /plan-ceo-review: Landscape Check before scope challenge
- /review: search-before-recommending for fix patterns
- /qa-only: WebSearch in allowed-tools
- /design-consultation: three-layer synthesis backport in Phase 2 Step 3
- /retro: eureka moment tracking from ~/.gstack/analytics/eureka.jsonl
All search steps include WebSearch fallback clause.

* fix: address Codex review — sanitize search, privacy gate, ETHOS.md sidecar
Three fixes from adversarial Codex review:
- /investigate: sanitize error messages before searching (strip hostnames,
IPs, file paths, SQL, customer data). Skip search if unsanitizable.
- /office-hours: add privacy gate before landscape search. Use generalized
category terms, never the user's specific product name or stealth idea.
- setup: link ETHOS.md into .agents/skills/gstack/ sidecar so workspace-
local Codex sessions can find the builder philosophy.

* fix: sanitize Phase 2 external pattern search in /investigate
The Phase 2 external search also sent raw error messages to WebSearch.
Apply same sanitization rule as Phase 3 search escalation.

* docs: sync documentation with shipped changes
- ARCHITECTURE.md: preamble now handles 5 things (add Search Before Building)
- CLAUDE.md: add ETHOS.md to project structure tree
- README.md: add ETHOS.md to docs table

* fix: check for bun before running setup (#147)
Users without bun installed got a cryptic "command not found" error.
Now prints a clear message with install instructions.

* fix: block SSRF via URL validation in browse commands (#17)
Adds validateNavigationUrl() that blocks non-HTTP(S) schemes (file://,
javascript:, data:) and cloud metadata endpoints (169.254.169.254,
metadata.google.internal). Applied to goto, diff, and newTab commands.
Localhost and private IPs remain allowed for local dev QA.
Closes#17

* fix: replace eval $(gstack-slug) with source <(...) (#133)
Eliminates unnecessary use of eval across all skill templates and
generated files. source <(...) has identical behavior without the
shell injection surface. Also hardens gstack-diff-scope usage.
Closes#133

* fix: rename /debug to /investigate to avoid Claude Code conflict (#190)
Claude Code has a built-in /debug command that shadows the gstack skill.
Renaming to /investigate which better reflects the systematic root-cause
investigation methodology.
Closes#190

* test: add unit tests for path validation helpers
validateOutputPath() and validateReadPath() are security-critical
functions with zero test coverage. Adds 14 tests covering safe paths,
traversal attacks, and prefix collision edge cases.

* chore: bump version and changelog (v0.8.3)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* docs: update /debug → /investigate references in docs
CLAUDE.md, README.md, and docs/skills.md still referenced the old
/debug skill name after the rename.

* fix: harden URL validation against hostname bypasses (Codex P1)
Codex review found that metadata IPs could be reached via hex
(0xA9FEA9FE), decimal (2852039166), octal, trailing dot, and IPv6
bracket forms. Now normalizes hostnames before checking the blocklist
and probes numeric IP representations via URL constructor.
Also moves URL validation before page allocation in newTab() to
prevent zombie tabs on rejection (Codex P3).
5 new test cases for bypass variants.
