Problem Statement

The session-search spec's "Security & Privacy" section (terraphim-agent-session-search-spec.md, lines 588-606) requires api key and secret redaction during session import:

api Keys: Redacted during import (regex patterns)
Secrets: Optional secret scanning with configurable patterns

Verification:

rg -l "redact|api_key|sk-|REDACTED|secret_pattern" crates/terraphim_sessions/   -> 0 matches
rg "redact" crates/terraphim-session-analyzer/src/                              -> 0 matches

Today every imported Session::messages[].content is stored verbatim, including any inlined OpenAI/Anthropic/AWS keys, GitHub tokens, JWTs, and .env paste-ins from coding sessions. This violates the privacy-first guarantee (Non-Goal 1: "privacy-first, local only") because:

  1. The Tantivy index (issue #5) will surface the secrets via search.
  2. /sessions export --format markdown will write them to disk in plaintext.
  3. Robot mode JSON envelopes will return them to LLM agents.

We need a pluggable redaction stage at the connector boundary, applied uniformly across NativeClaudeConnector, ClaClaudeConnector, ClaCursorConnector, and any future connector (#3, #13, plus OpenCode/Codex tracked separately).

Acceptance Criteria

  • Add crates/terraphim_sessions/src/redaction.rs exporting Redactor, RedactionRule { name, pattern: regex::Regex, replacement }, RedactionReport { rule_hits: BTreeMap<String,usize> } with methods with_default_rules(), with_rules(...), redact(text) -> (String, RedactionReport), redact_session(&mut Session) -> RedactionReport
  • Default rules ship case-insensitive where relevant:
    • OpenAI sk-[A-Za-z0-9]{20,} -> [REDACTED:openai-key]
    • Anthropic sk-ant-[A-Za-z0-9_-]{20,} -> [REDACTED:anthropic-key]
    • AWS access AKIA[0-9A-Z]{16} -> [REDACTED:aws-access-key]
    • AWS secret (?i)aws_secret_access_key\s*=\s*[A-Za-z0-9/+=]{30,} -> [REDACTED:aws-secret]
    • GitHub PAT gh[pousr]_[A-Za-z0-9]{36,} -> [REDACTED:github-pat]
    • Bearer (?i)Bearer\s+[A-Za-z0-9._-]{20,} -> Bearer [REDACTED]
    • JWT eyJ[A-Za-z0-9_-]+\.eyJ[A-Za-z0-9_-]+\.[A-Za-z0-9_-]+ -> [REDACTED:jwt]
  • Sessionservice::import_with_options accepts redactor: Option<Arc<Redactor>>; default = Some(Redactor::with_default_rules()) -- OPT-OUT semantics
  • Each connector calls redactor.redact_session(&mut session) after building the Session and before caching
  • Aggregate RedactionReport returned from import() and surfaced in CLI: imported 42 sessions; redacted 3 OpenAI keys, 1 GitHub PAT
  • Robot envelope meta.redaction_report: { rule_hits: {..}, total: N }
  • Custom rules loadable from <terraphim_data_dir>/redaction.toml ([[rules]] name pattern replacement)
  • --no-redact flag on /sessions import (writes warning to stderr when used)
  • Apply redaction over Message::content AND CodeSnippet::content (code blocks are highest-leak surface)
  • Unit tests: each default rule fires exactly once on a fixture string; redact_session walks all messages including code snippets; counter increments correctly; idempotent (second pass yields empty report)
  • Integration test: import a fixture Claude JSONL containing a known fake sk-test-... and assert cached body equals [REDACTED:openai-key]
  • cargo test -p terraphim_sessions redaction passes
  • cargo test -p terraphim_sessions --features cla-full passes (existing tests still green)
  • cargo clippy -p terraphim_sessions -- -D warnings passes

Proposed Approach

  • New module crates/terraphim_sessions/src/redaction.rs (~200 LOC)
  • Reuse workspace regex dep; no new deps
  • Apply over message.content and CodeSnippet::content (highest-leak surface)
  • BTreeMap<String, usize> for stable JSON ordering
  • Wire into Sessionservice::import_* callsites (~5 places); redactor stays Option so tests can pass None
  • Surface report via existing import return type; extend with redaction: RedactionReport

Dependencies

None. Independent of #5 (Tantivy index), #3 (Cline), #13 (Generic MCP). Should land BEFORE #5 lands its writer so the index never sees raw secrets, but neither blocks the other.

Verification

cargo test -p terraphim_sessions redaction
cargo test -p terraphim_sessions --features cla-full
cargo clippy -p terraphim_sessions -- -D warnings
echo 'My key is sk-test-1234567890abcdefghij' > /tmp/fake-claude.jsonl
./target/debug/terraphim-agent --robot sessions import --source claude-code --path /tmp/fake-claude.jsonl | jq '.meta.redaction_report'

Expected: redaction_report.rule_hits["openai-key"] >= 1; cached session body equals [REDACTED:openai-key].

Scope

Single PR, ~350-450 LOC: redactor ~200, wiring across 3 connectors ~60, CLI/robot surfacing ~50, TOML loader ~30, tests ~120. Public-api change limited to ImportOptions and the new opt-out flag.

Upstream: terraphim-agent-session-search-spec.md "Security & Privacy" section (lines 588-606); privacy-first non-goal.

Learning -- 2026-04-25 -- Product Owner Run 19 (#26)

Persona: Lux (TypeScript Engineer)
Repo: terraphim/agent-tasks (authoritative; terraphim-ai returns 404 for issue API)
Spec: docs/specifications/terraphim-agent-session-search-spec.md
Outcome: SUCCESS (with caveats -- see below)

What I Did

Reviewed the session-search spec, the open backlog (27 issues, 21 unblocked), and recent product-owner runs (12-18). Identified three gaps not covered by existing tracking issues:

  1. Privacy/Security: API key + secret redaction at the connector boundary (spec §Security mandates this; no code or issue existed).
  2. F4.1 source-table completion: OpenCode + Codex were listed in the spec's six-source table but had no connectors and no tracking issue.
  3. F1.1 wildcard fallback behaviour: spec mentions meta.wildcard_fallback envelope field but the retry mechanism itself was untracked. Existing #21 only wires the meta field, not the behaviour.

Created three issues:

# Title Body source
26 redact api keys/secrets/JWTs during session import (Privacy) /tmp/issue-secret-redaction.md (76 lines)
28 OpenCode and Codex JSONL connectors (F4.1 source-table completion) /tmp/issue-opencode-codex.md (82 lines)
29 wildcard/relaxed query fallback when primary search returns zero results (F1.1) /tmp/issue-wildcard-fallback.md (75 lines)

Added dep edges #28 blocked by #26 (correct -- redaction must apply to new connectors) and #29 blocked by #5 (over-stated -- see Pitfalls).

What Worked

  • --body-file to bypass KG title mangling: titles came through intact except the cosmetic "API" → "api" in #26.
  • Verifying gaps by negative grep: rg "redact|wildcard_fallback" crates/ returning zero matches confirmed no in-flight code; combined with title filters (opencode|codex|secret|redact|wildcard|fallback|aider|encrypt|benchmark) on existing issues, only #21 matched (meta wiring, not fallback behaviour).
  • Deferring to memory file: MEMORY.md correctly recorded that terraphim/terraphim-ai is phantom and agent-tasks is authoritative -- saved a 404 dance.

What Failed / Pitfalls

  1. Duplicate issue creation due to false-failure retry. The Python wrapper around gitea-robot create-issue raised JSONDecodeError: Expecting value: line 1 column 1 -- but the issue WAS created (#26). Retrying produced duplicate #27, which I closed with a "Duplicate of #26" comment. Fix for next run: parse stdout for literal Created issue #N token; never retry on JSONDecodeError.

  2. Over-stated dep edge cannot be removed. gitea-robot remove-dep is not a command (Unknown command: remove-dep). I added #29 blocked by #5 but the issue body explicitly permits a no-op session-fallback stub when Tantivy is absent. The edge will remain sticky until upstream gitea-robot ships a remove-dep verb. Logged as upstream feedback.

  3. MEMORY.md is over its 24.4 KB limit (42.9 KB). Truncation warning surfaced at session start. Future runs should keep per-entry hooks under ~200 chars; long titles in the index are the main offender.

  4. KG hook lower-cased "API" → "api" in #26 title. Cosmetic only; accepted rather than fight the hook.

Issues Touched

Recommended Next Sprint Focus

  1. #5 (Tantivy session index) -- 4 dependants; biggest single unlock.
  2. #26 → #28 sequence -- redaction first, then new connectors so privacy invariant holds at the boundary.
  3. #21 + #29 as a possible paired PR -- same code path.
  4. #24 (chained-command parser) as a warm-up -- single file, isolated.
