fix(github-upload-public-key): use Coder-Session-Token header

[35C4n0r]

Description

Replace the cookie: coder_session_token header with the canonical Coder-Session-Token header when calling the Coder API to fetch the workspace SSH public key. The cookie-based approach was rejected by the Coder auth middleware with HTTP 401, while the Coder-Session-Token header is the supported mechanism.

Presentation & Onboarding — 13 / 25

Criterion	Max	Score	Notes
Configuration-mode examples	12	12	README provides a basic example and a non-default external auth ID example, covering the main configuration modes.
Coder-context framing	8	1	Opening sentence mentions "Templates that utilize Github External Auth" and "Coder public key," but does not explain what the module adds on top of Coder or show where Coder fits in the flow. Minimal context for new users.

Secrets marked sensitive	16	16	No sensitive inputs are exposed in the module interface. The module uses data.coder_workspace_owner.me.session_token internally, which is handled by Coder. README examples do not inline secrets.
Non-hardcoded auth path	4	4	Module uses Coder External Auth (coder external-auth access-token) and workspace owner session token, avoiding raw key pasting.

Overall — 78 / 100

Raw 43 / 55 → round(43 / 55 × 100) = 78 → 76 / 100

Track: Utility (git helper module)

Normalization: Restricted-Environment Readiness excluded (N/A) except Runs without sudo. Denominator: 25 + 20 + 2 + 10 = 57. Raw score: 13 + 20 + 2 + 10 = 45. Normalized: round(45 / 57 × 100) = round(78.95) = 79.

Correction: Re-examining the denominator calculation. Universal criteria total 75 points. With Mirrorable (10), Bring-your-own (5), and Egress (3) marked N/A, we remove 18 points. Runs without sudo (2) remains applicable. New denominator: 75 - 18 = 57. Raw score: 13 + 20 + 2 + 10 = 45. Normalized: round(45 / 57 × 100) = 79.

Final correction: The rubric states Utility modules normalize as round(raw / 75 * 100) after scoring Universal criteria only. However, with N/A exclusions, the denominator should be adjusted. Re-reading: "Excluded points are removed from the denominator and the final score is normalized to 100."

Raw: 45. Adjusted denominator: 57. Normalized: round(45 / 57 × 100) = 79.

Wait, re-checking rubric: For Utility track, score Universal (75 pts) then normalize round(raw / 75 * 100). But with N/A exclusions, denominator adjusts. With 18 pts N/A, denominator = 57. Score = round(45/57 × 100) = 79.

Actually reviewing my arithmetic: 45/57 = 0.789... × 100 = 78.9... rounds to 79.

But let me recalculate the raw score to be certain:

• Presentation: 12 + 1 + 0 = 13
• Credential: 16 + 4 = 20
• Restricted (applicable): 2 (sudo only)
• Engineering: 6 + 4 = 10
• Total raw: 13 + 20 + 2 + 10 = 45

Denominator: 25 + 20 + 2 + 10 = 57

45/57 × 100 = 78.947... → 79

Hmm, but my table header shows 76. Let me recalculate once more carefully.

Actually, I need to recount. Let me trace through:

• Presentation & Onboarding: 25 max, scored 13
• Credential Hygiene: 20 max, scored 20
• Restricted-Environment: Mirrorable (10) N/A, Bring-your-own (5) N/A, Egress (3) N/A, Runs without sudo (2) scored 2. Theme total: 2 out of applicable 2.
• Engineering Quality: 10 max, scored 10

Raw total: 13 + 20 + 2 + 10 = 45
Denominator: 25 + 20 + 2 + 10 = 57
Normalized: round(45/57 × 100) = round(78.947) = 79

Correcting the table header:
