# Session Log - 2026-08-10

Agent: Claude Code
Model: Claude Sonnet 5 (claude-sonnet-5)
P4 identity used: bot_Claude_Anthropic (except where noted)

## Summary

First working session on the SDP Classic-to-Streams migration project. Covered onboarding, a review pass on the Task 1-1.3 background docs, a round of doc corrections and small P4 housekeeping, and completed Task 1.1 (new 7-instance EC2 test fleet launched, verified, and a security cleanup after Lee Marzke's departure from Perforce).

## Timeline

1. **Onboarding / agent strategy** - Reviewed `CLAUDE.md`, `P4Info.md`, `ProjectKickoff.md` as instructed. User asked for advice on model/agent selection given the project's scope. Recommendation: stay on Sonnet 5 for the main session; use targeted `Explore`/`general-purpose` subagents later for research-heavy side-lookups (e.g. AMI selection, P4 DVCS mechanics) rather than the heavier multi-agent `Workflow` orchestration, which isn't warranted yet.

2. **Review of Task 1-1.3 background material** - Read `ProjectKickoff.md`, `P4Info.md`, `SDPTestSuite-SDPInstaller.md`, `SDPTestSuite-BattleSchool.md`, `SDPTestSuite-DockerPodman.md`. Flagged 7 confusing/unclear items:
   - Three different spellings of the new test-suite depot/stream name in `ProjectKickoff.md` (`test_sdp_install` / `test-sdp_install` / `test-install_sdp`)
   - A literal duplicate path (`//test-install_sdp/dev or //test-install_sdp/dev`)
   - `//p4/sdp/dev_rebrand` typo (should be `//p4-sdp/dev_rebrand`)
   - Non-existent AWS instance family names (`t3g`, `t4`, `r5`)
   - Zero-cost AMI requirement possibly conflicting with SLES 15 marketplace licensing
   - Unstated region/local-directory assumptions for the new EC2 fleet's ssh scripts
   - Minor typos (`Ubunu`, inconsistent `u20x86-64` hyphen vs. underscore convention)

3. **User provided corrections** for all of the above. Implemented:
   - `p4 edit` + fixed `ProjectKickoff.md`: canonicalized depot name to `//test-install_sdp`, fixed the duplicate path (second one is `main`), fixed `//p4-sdp` typo, rewrote the EC2 instance-type guidance (`t` family, latest generation available, `small` size not `micro`, `g` suffix for aarch64, usability over absolute lowest cost), added a SLES 15 zero-cost exception note, and added a note that the local ssh-script/pem directory maps to `//BattleSchool/main/aws/pem/us-east-2` on PPN and will need new scripts added/submitted there later.
   - `p4 edit` + fixed `P4Info.md`: added a "How the P4CONFIG Hierarchy Works" section (`~/pub` and `~/ppn` set P4USER/P4PORT; subdirectories set P4CLIENT; both personal and bot credential files exist at every level), fixed an "idae" -> "idea" typo. Confirmed `bot_Claude_Anthropic` casing was already correct throughout (user had suspected a lowercase variant existed in the doc; it didn't -- the lowercase variant turned out to be in the shell's `P4CONFIG` env var itself, which is outside these tracked files and was left alone).

4. **BattleSchool (PPN) housekeeping** - Renamed `ssh-install_sdp-test-u20x86-64.sh` -> `ssh-install_sdp-test-u20x86_64.sh` via `p4 move -r` in the `//BattleSchool/main/aws/pem/us-east-2` workspace, for underscore-naming consistency with the other platform-tagged scripts. Hit a P4 protections snag first (`bot_Claude_Anthropic` got "protected namespace - access denied" on that path); user fixed the protections table mid-session and the rename went through cleanly on retry.

5. **Submits**:
   - Change `33155` (Public Depot, `//test-install_sdp/dev`) - the `ProjectKickoff.md` / `P4Info.md` doc corrections.
   - Change `2761835` (PPN, `//BattleSchool/main`) - the `u20` ssh script rename.

6. **P4Info.md tidbit: `ai_dev_support/` isolate path** - Documented that `//test-install_sdp/main`'s stream Paths field has `isolate ai_dev_support/...` (inherited by `dev`), so this folder's contents (session logs, support files) are exempt from Merge Down / Copy Up. Recorded the general rule that submits touching `ai_dev_support/` should be mutually exclusive with submits touching any other folder. Submitted separately as change `33156`, leaving this session log itself opened for add per the user's instruction.

7. **Task 1.1: Launched the new EC2 test fleet.** Used the AWS CLI (identity `helix-bsw-bot`) to research the current 8-machine fleet (via public IP lookups matching the existing ssh wrapper scripts) and built a reuse plan for 7 platforms (dropping EOL Ubuntu 20):
   - Confirmed all 7 current AMIs are still `available` in us-east-2 and reused them as-is.
   - Confirmed the SLES 15 AMI (`ami-0a752653199c4fce6`) has no `BillingProducts`/`ProductCodes` attached, supporting the zero-cost exception.
   - Checked available `t*.small` offerings in us-east-2 (`t2`, `t3`, `t3a`, `t4g` -- no t5/t6 yet); used `t3.small` for x86_64 (unchanged) and upgraded the aarch64 box from `t4g.micro` to `t4g.small` per the "small not micro" guidance.
   - Reused each predecessor instance's exact security group and subnet 1:1 by platform, so the existing SSH allowlist carried over without creating new SGs.
   - Validated the full launch plan with `--dry-run` (no cost) before presenting it to the user for go-ahead.
   - Launched all 7 instances, waited for `running` state, and verified SSH connectivity to every one.
   - Created and end-to-end tested 7 new `ssh-test-install_sdp-<PlatformTag>.sh` wrapper scripts in `/Users/ttyler/ppn/BattleSchool/aws/pem/us-east-2`, matching the format of the existing scripts (`text+x` filetype).
   - Submitted as change `2761836` (PPN, `//BattleSchool/main`).

8. **Security cleanup: Lee Marzke's departure from Perforce.** After reviewing the new-fleet plan, the user caught that one reused security group (Rocky 9, shared by both the old and new r9x86_64 instances) still had an SSH rule for Lee Marzke's IP (`71.163.38.18/32`). Swept every security group in the VPC (`vpc-2df14445`) for that CIDR and found four total:
   - `sg-0abda4305e43a47bf` (Rocky 9, in-scope -- shared by old instance `install_sdp-test3-r9x86_64` and new instance `test-install_sdp-r9x86_64`): Lee's SSH rule removed, Tom's kept.
   - `sg-05c6a86f287351a6f` ("P4Consultants", unattached/out-of-scope): Lee's SSH rule removed on user's request.
   - `sg-0e7d54145a336fadf` (orphaned Swarm-related SG, unattached/out-of-scope): Lee's SSH/80/443 rules removed on user's request; Tom's rule and the self-referencing P4D/1666/1999 rules untouched.
   - Confirmed no other security group in the VPC references that CIDR.

## Open Items / Not Yet Started

- Task 1.2 / 1.3: Update and install the SDP Installer Test Suite (source-swapping capability, remote specs) -- not yet started, needs more detailed design.
- Shell-level `P4CONFIG` env var casing mismatch (`.p4config.bot_claude_anthropic` vs actual `.p4config.bot_Claude_Anthropic` files) noted but not fixed -- lives outside version control.
- The two out-of-scope, unattached security groups (`P4Consultants`, orphaned Swarm SG) still exist otherwise untouched -- worth revisiting if/when those resources are reused.
