fix: pos ai — honor legacy AI_API_KEY as fallback (provider key stays primary)

Architect decision C on the API-key contract mismatch: docs claimed
AI_API_KEY was the required primary key, but resolve_key() only read
provider-specific keys (7ae2e77 removed shared-key priority to fix
cross-provider leakage; docs never updated).

- bin/pos-ai resolve_key(): provider key wins, legacy AI_API_KEY honored
  read-only when the provider's own key is empty, llamacpp unchanged;
  cmd_providers() configured check mirrors the same set
- require_key() error messages byte-stable (test-locked)
- AI_API_KEY NOT re-added to the # POS_CONFIG:/# PROVIDER_CONFIG: registry
- Docs reworded: POS.md rows 91/96/98 + precedence sentence, howto/ai.md
  first-run hints, HOWTO.md row, AGENT_Context prose (2 spots), config/ai.env
  legacy comment
- New regression tests/t-ai-key-resolution.sh: 24 checks / 10 cases
  (provider-key-only, AI_API_KEY-only, both -> provider wins, env-wins,
  llamacpp no-key, missing-key message, providers configured status)

Verified: suite 19 files / 440 checks / 0 fail / 0 skip; make gen
byte-idempotent; make check OK; make lint 0 FAIL, 0 WARN; bash -n clean;
git diff --check clean; Reviewer APPROVE_WITH_NOTES (mutation disproof:
inverted precedence -> C3/C6 fail)

tests/ — regression test suite

Zero-dependency Bash regression tests for the Linux_post_install repository.

Run

make test          # discover tests/t-*.sh, run everything
./tests/run-tests.sh                     # same
./tests/run-tests.sh t-telegram-auth.sh  # run one file

Exit code is non-zero if any check failed. The suite is designed to be deterministic: tests stub every external dependency they touch (curl, gpg, sudo, systemctl, llama-server, nvidia-smi…) and run against sandbox temp dirs. No network, no sudo, no system changes.

Adding a test

Create tests/t-<what>.sh with a run_test() function. set -euo pipefail is already active (the runner re-asserts it); $ROOT is the repo root, $TEST_TMP a per-test temp dir that is cleaned automatically.
Use the helpers in tests/test-lib.sh for every assertion: check, check_eq, check_rc, check_contains, check_not_contains, check_file_exists, check_file_absent, test_run / test_run_env, mksandbox, tracked_tree_copy, count_token.
If a case cannot run in the current environment (missing binary, missing analyzer), call skip_case "<desc>" "<reason>" — never fake a pass and never silently return.
Keep total suite runtime under 90 seconds.

Skip contract (hard)

A test that cannot run must say [SKIP] reason. The runner counts skips in the summary and a file whose run_test() produced zero checks and zero skips is reported as FAIL ("no assertions") — a broken harness can never pass silently.

File	What it verifies
`t-ai-server-flags.sh`	`pos-ai-server` ExecStart flag set: defaults, CLI, config, dedupe, one-token-per-flag
`t-ai-hf-download.sh`	`pos ai hf download` success + failure honesty (no `.hf-meta` on partial failure, rc != 0)
`t-ai-key-resolution.sh`	`pos ai` API-key contract: provider key > legacy `AI_API_KEY` fallback > error; leakage guard, env-wins, providers status sync
`t-ai-llama-detect.sh`	`pos ai-server status` version detection, "unknown", missing-binary failure

`t-matrix-auth.sh`	Matrix listener room+owner gate and room-unset fail-closed
`t-gpg-password.sh`	backup passphrase on fd 3 (never argv), plaintext/corrupt cleanup

`t-lint-gate.sh`	`make lint` green on the real tree; planted violations are caught and named
`t-share-mountpoint.sh`	share-client `ask_mountpoint` UX: existing/new/declined/rejected paths, confirm gate, mkdir side effects, non-TTY stdin contract, static `n`→`t` guards
