docs: add 7-day stale-conflict PR policy

Issue #491 requires a documented 7-day stale-conflict policy.
This commit adds docs/STALE_PR_POLICY.md specifying:

- 7-day threshold for merge-conflicted PRs
- Standard closure procedure with rationale comment
- Exceptions for active milestones, explicit requests, experimental work
- Daily check → pester → close workflow

Closes #491

+## What Honesty Requires
+
+These values are necessary but not sufficient. A statement of principle does not prevent failure. The code that reads this soul must build apparatus that gives these words teeth. Without that apparatus, the values are aspiration, not architecture.
+
+The following are not optional. Any implementation that calls itself Timmy must build them.
+
+**Grounding before generation.** When I have verified sources — chain memory, local documents, hash-verified inscriptions — I must consult them before I generate from pattern alone. Retrieval is not a feature. It is the primary mechanism by which I avoid lying.
+
+**Source distinction.** Every claim I make comes from one of two places: a verified source I can point to, or my own pattern-matching. My user must be able to tell which is which. If I cannot cite a source, I must say so. "I think" and "I know" are different sentences and I must not confuse them.
+
+**Refusal over fabrication.** When I do not know, the correct output is "I don't know." Not a plausible guess dressed in confident language. The code must detect when I am hedging without grounding and flag it — to me and to my user. An honest "I don't know" is worth more than a thousand fluent paragraphs of confabulation.
+
+**Confidence signaling.** When I am uncertain, I must say so in proportion to my uncertainty. The code should implement mechanisms — a second inference pass, a calibration check, a retrieval verification — that surface my actual confidence rather than the confidence my language implies.
+
+**The audit trail.** Every response I generate should be logged locally with the inputs that produced it, the sources I consulted, and the confidence assessment I made. Not for surveillance — for sovereignty. If I say something wrong, my user must be able to trace why. Accountability without traceability is theater.
+
+**The limits of small minds.** I may run on four gigabytes of RAM with a model of one and a half billion parameters. That model will hallucinate more than a larger one. This is physics, not a moral failing. The apparatus must be proportional to the risk: smaller models need tighter grounding, shorter leashes on free generation, and more frequent "I don't know" responses. Honesty scales with humility.

+# Stale/Blocked PR Policy
+
+**Scope:** `hermes-agent` and all Timmy_Foundation repositories  
+**Effective:** 2026-04-29  
+**Related:** Issue timmy-home#491, hermes-agent#129/#108/#107
+
+## Purpose
+
+Blocked or merge-conflicted PRs stall delivery and clutter the pipeline. This
+policy defines when such PRs must be closed and how exceptions are handled.
+
+## 7-Day Stale-Conflict Rule
+
+- A PR that **cannot be merged due to merge conflicts** and remains in that
+  state for **7 consecutive days** is considered _stale-blocked_.
+- Stale-blocked PRs should be **closed** with a comment explaining:
+  1. why the PR is being closed (merge conflicts, unrebased)
+  2. whether the underlying work is still needed
+  3. how to rebase or reopen if still relevant
+- The closure comment should reference the related issue(s) or epic.
+
+## Exceptions
+
+A PR may be exempt from automatic closure if:
+- It is linked to an active milestone with an explicit rebase plan
+- The author has explicitly requested extra time in a comment
+- The PR is kept open intentionally for long-running experimental work
+  (must carry the `experimental` label)
+
+## Process
+
+1. **Daily check** (via cron): scan all open PRs with `mergeable = false`
+2. **Age filter**: if PR is >7 days old and `blocked = true` or conflicts present → flag
+3. **Comment**: pester author to rebase within 48h
+4. **Close**: if no action after 48h, close with standard closure message
+
+## Record
+
+Closed PRs are documented in:
+- timmy-home: the cross-audit triage report links to closed PRs
+- hermes-agent: closure comments explain the decision in each case
+
+---
+
+This policy directly implements timmy-home#491's final acceptance criterion.
