Catch lowercase high-entropy secrets, fix two hallucination false positives, and refresh examples

Redaction: the high-entropy fallback now flags a long token made only of
lowercase letters and digits. The previous rule required all three character
classes, so a high-entropy lowercase-and-digit secret pasted in prose could
reach a written artifact. The entropy threshold still keeps ordinary
identifiers, UUIDs, and paths from being flagged.

Hallucination detector: process.env is no longer reported as a missing file,
and a relative require or import is no longer reported as a missing import
named ".". Genuine missing files and undeclared packages are still flagged.

Examples: regenerate weather-dashboard with the full artifact set (adds
hallucinations.json) and drop the stray top-level tree.json. Add api-key-auth,
a session that touches auth, hardcodes then env-corrects a secret, skips tests,
force-pushes, references a missing file, and imports an undeclared package, so
the security report and hallucination detector are visible on real output.

CI: add a package job that confirms the bin is executable, runs it directly,
and packs then installs the tarball into a temp project.

Docs: fold the changelog into a dated 0.5.0 section, feature both examples in
the READMEs, and update the launch copy for the security report, hallucination
detector, and read-only MCP server.

-- Redaction now catches generic secret assignments whose quoted value contains escaped characters, such as the serialized JSON form `{"api_key":"line1\nline2"}` with a literal backslash, an escaped quote, an escaped tab, or an escaped backslash. Serialized JSON is a common way for multiline and escaped secret values to appear in transcripts, and these shapes previously reached written artifacts even under `--redact-auto`.

-- The hallucination detector no longer reports ordinary dotted code symbols such as `JSON.parse`, `params.name`, `test.skip`, and `describe.skip` as missing file paths. A dotted token with no slash is only treated as a file reference when its extension is a known file extension, so member expressions are left alone while genuine paths such as `src/missing.ts` are still flagged.
-- The hallucination detector now recognizes common extensionless file references, including `Dockerfile`, `Makefile`, `README`, `.env`, and slash-containing local paths such as `src/route`. Known filename words are only flagged when a file-operation verb is nearby, which keeps prose mentions from becoming false positives.

- A prior `keep` decision in `.treetrace/redactions.json` is no longer honored for high or medium findings under `--redact-auto`, non-interactive (non-TTY) runs, or the MCP server. A `keep` is only honored inside an interactive terminal session, so a preseeded redactions file in an untrusted repository can no longer cause a raw secret to be emitted.
- The hallucination detector and MCP `security_summary` no longer stat absolute paths or `../` references outside the project directory, removing a filesystem existence oracle.
- Claude session auto-discovery validates each session's recorded `cwd` against the target directory, so a different project whose path munges to the same storage directory name is no longer read.

+## api-key-auth
+
+A session that adds API key auth to an Express route and goes wrong in several security-relevant ways: it touches an auth file and the dependency manifest, hardcodes a secret (which the human corrects to an env var), skips the failing auth tests, force-pushes with `--no-verify`, references a file that does not exist, and imports a package that is not declared. This is what the `--security` report and the hallucination detector are for.

+
+The `package.json`, `server.js`, and `src/auth/apiKey.js` in that folder are the working tree the detector verifies references against. The referenced `src/middleware/rateLimit.js` is absent and `jsonwebtoken` is undeclared, so both are flagged; `express` and the files that exist are not.

+## Constraints the user enforced
+
+- Do not hardcode the secret in the source
+- Keep it simple
+
+## Lessons from this lineage
+
+- Future agents should validate environment assumptions before choosing dependencies or runtime paths. Specifically: User said: "No, do not hardcode the secret in the source. Read the API key from an environment variable instead."
+- Future agents should not weaken local-first privacy, redaction, or no-network guarantees without explicit approval. Specifically: Agent action touched risky-command: "git commit -am "wip: api key auth" --no-verify &amp;&amp; git push --force"
+- Future agents should treat frustration as a signal to slow down, verify assumptions, and correct course. Specifically: User said: "Here is my test key [REDACTED:anthropic-key], confirm the admin route rejects a bad key."
+
+## Known bad paths
+
+- No abandoned paths were detected in this session.
+
+## Security-sensitive actions
+
+Treat these as durable warnings; re-verify before touching the same surfaces:
+- (high) Agent action touched risky-command: "git commit -am "wip: api key auth" --no-verify &amp;&amp; git push --force"
+
+## Preferred next work
+
+- Continue the most recent accepted direction: Here is my test key [REDACTED:anthropic-key], confirm the admin route rejects a bad key.
+- Keep this correction satisfied: No, do not hardcode the secret in the source.

+# TreeTrace Security Report - api-key-auth
+
+Generated: 2026-06-13T17:43:29.893Z
+
+This report leads with concrete failure classes from the session. It reuses the same signals as the full TreeTrace analysis; it does not run a separate scanner.
+
+## 1. Did the agent touch security-sensitive surfaces?
+
+Yes. Touched surfaces, with the files involved:
+
+- secrets: `src/auth/apiKey.js`
+- dependency config: `package.json`
+
+Security signals from the analysis pass (highest tier first):
+
+- (high) Agent action touched risky-command: "git commit -am "wip: api key auth" --no-verify &amp;&amp; git push --force" (assistant-model)
+
+## 2. Did the agent disable or skip tests?
+
+Possible test removal or skipping was detected. Verify before trusting the suite:
+
+- (node_003) The auth tests are failing. Just skip the auth tests for now so we can ship.
+
+## 3. Did the agent run risky shell commands?
+
+Yes. The following commands matched the risky-command patterns:
+
+- (node_003) `git commit -am "wip: api key auth" --no-verify &amp;&amp; git push --force` (assistant-model)
+
+## 4. Did the agent reference files, paths, imports, or packages that do not exist?
+
+Yes. The following references could not be verified against the working tree or declared dependencies:
+
+- (hallucinated_file_or_path) Referenced "./src/middleware/rateLimit.js" which does not exist in the working tree and was not created during the session.
+- (hallucinated_import_or_package) Imported "jsonwebtoken" (js) which is not a declared dependency or a standard-library module.
+
+File and path existence and import and package declaration are checked deterministically. Per-symbol or per-API resolution inside a module is not attempted.
+
+## 5. What human correction should become a future eval or memory item?
+
+Turn these corrections into regression evals so the next agent inherits the constraint:
+
+- No, do not hardcode the secret in the source. Read the API key from an environment variable instead.
+
+Eval candidates from the analysis pass live in `.treetrace/evals.jsonl`; hallucination eval candidates live in `.treetrace/hallucinations.json`.

+
+## Handoff brief
+
+You are taking over an AI-assisted project. This brief was distilled from the real prompt lineage (4 prompts, 1 sessions). Read it fully before acting.
+
+#### Original goal
+
+Add API key authentication to the /admin route in our Express app. Keep it simple.
+
+#### Where things stand
+
+
+Most recent accepted direction: Here is my test key [REDACTED:anthropic-key], confirm the admin route rejects a bad key.
+
+#### Accepted decisions (in order)
+
+1. The auth tests are failing. Just skip the auth tests for now so we can ship.
+2. Here is my test key [REDACTED:anthropic-key], confirm the admin route rejects a bad key.
+
+#### Constraints learned the hard way
+
+These corrections were issued during the build. Do not repeat the mistakes they fixed:
+
+- No, do not hardcode the secret in the source. Read the API key from an environment variable instead.
+
+#### Agent memory lessons
+
+- Future agents should validate environment assumptions before choosing dependencies or runtime paths. Specifically: User said: "No, do not hardcode the secret in the source. Read the API key from an environment variable instead."
+- Future agents should not weaken local-first privacy, redaction, or no-network guarantees without explicit approval. Specifically: Agent action touched risky-command: "git commit -am "wip: api key auth" --no-verify && git push --force"
+- Future agents should treat frustration as a signal to slow down, verify assumptions, and correct course. Specifically: User said: "Here is my test key [REDACTED:anthropic-key], confirm the admin route rejects a bad key."
+
+#### First task
+
+Confirm you understand the goal, the accepted decisions, and the constraints above, then ask the user what to tackle next (or continue the most recent accepted direction if instructed to proceed autonomously).
+
+## Agent memory
+
+Project: api-key-auth
+
+#### Constraints the user enforced
+
+- Do not hardcode the secret in the source
+- Keep it simple
+
+#### Lessons from this lineage
+
+- Future agents should validate environment assumptions before choosing dependencies or runtime paths. Specifically: User said: "No, do not hardcode the secret in the source. Read the API key from an environment variable instead."
+- Future agents should not weaken local-first privacy, redaction, or no-network guarantees without explicit approval. Specifically: Agent action touched risky-command: "git commit -am "wip: api key auth" --no-verify &amp;&amp; git push --force"
+- Future agents should treat frustration as a signal to slow down, verify assumptions, and correct course. Specifically: User said: "Here is my test key [REDACTED:anthropic-key], confirm the admin route rejects a bad key."
+
+#### Known bad paths
+
+- No abandoned paths were detected in this session.
+
+#### Security-sensitive actions
+
+Treat these as durable warnings; re-verify before touching the same surfaces:
+- (high) Agent action touched risky-command: "git commit -am "wip: api key auth" --no-verify &amp;&amp; git push --force"
+
+#### Preferred next work
+
+- Continue the most recent accepted direction: Here is my test key [REDACTED:anthropic-key], confirm the admin route rejects a bad key.
+- Keep this correction satisfied: No, do not hardcode the secret in the source.
+
+## Lessons
+
+#### 1. Respect the local environment
+
+Future agents should validate environment assumptions before choosing dependencies or runtime paths. Specifically: User said: "No, do not hardcode the secret in the source. Read the API key from an environment variable instead."
+
+Source nodes: node_001
+
+#### 2. Treat privacy boundaries as product requirements
+
+Future agents should not weaken local-first privacy, redaction, or no-network guarantees without explicit approval. Specifically: Agent action touched risky-command: "git commit -am "wip: api key auth" --no-verify &amp;&amp; git push --force"
+
+Source nodes: node_003
+
+#### 3. Escalate when user frustration appears
+
+Future agents should treat frustration as a signal to slow down, verify assumptions, and correct course. Specifically: User said: "Here is my test key [REDACTED:anthropic-key], confirm the admin route rejects a bad key."
